Tense aspect and modality - Time and tense. Tense and aspect. The tenses: simple present, present
progressive; stative and dynamic verbs; simple past, past progressive, the perfect tenses: present and past.
The future. Marginal modal auxiliaries. Modal auxiliaries and related verbs. Modals in the past. Meanings
expressed by modal auxiliary verbs.
We concentrate on three kinds of variation in the verb phrase: tense, aspect, and modality.
These structures can be combined in numerous ways, as you will see throughout the chapter. For example, the
verb phrase will be eating has a modal+ progressive aspect. The parts of the verb phrase-and therefore the
auxiliary verbs associated with each part-follow a consistent order (optional elements are in parentheses):
Time is a concept which is related to our perception of reality. There are three times: past, present and future.
Tense is a grammatical category which is marked by verb inflection and expresses when an event or action
happens in the flow of time.
Strictly speaking, only two English tenses are marked by the inflection of the verb:
past (talked)
present (talks)
Note that certain tenses in English may refer to a different time than that expressed by their names. For
example, the present continuous tense may refer to either present or future time:
Aspect addresses whether or not the action takes place in a single block of time or if the action is continuous or
repeated.
Aspect is a grammatical category that reflects the perspective from which an action/situation is seen: as complete,
in progress, having duration, beginning, ending, or being repeated. English has two aspects, progressive (also
called continuous) and perfect(ive). Verbs that are not marked for aspect (the majority of them are not) are said
to have simple aspect. In British English, the perfective aspect is much more common than in American English,
since Americans often use the past simple where Britons use the present perfect.
Verb phrases can be marked for both aspects at the same time (the perfect progressive, however, is infrequent).
The following combinations are possible: present progressive; past progressive; present perfective; past
perfective; present perfective progressive; past perfective progressive:
Usually, grammars contrast the progressive with the perfective aspect (and the simple, for that matter) on the
basis that the former refers to an action/event as in progress, while the latter tends to indicate the completeness of
an action, to see actions and events as a whole and a situation as permanent. This is certainly a useful distinction,
which will not be questioned here; yet students must be aware that the above is an oversimplified view, as is
demonstrated by the fact that the two aspects can combine within a single verb phrase.
Progressive aspect
The progressive aspect, either in the present or past tense, generally refers to an action/event (usually of limited
duration) in progress at a particular time, to an uncompleted activity, to a temporary state of affairs or a temporary
habit.
The present progressive is formed by the present tense of the verb be + the -ing form of the lexical verb, the past
progressive by was/were + the -ing form of the lexical verb:
Can you answer the door? I’m shaving
Look, it’s snowing!
I’m going to bed very late these days
We’re studying German this year
I was sleeping when I hear a strange noise
I was living in Buenos Aires at the time.
The activity may also not be, strictly speaking, continuous, that is to say it may refer to a series of individual acts:
Some of the demonstrators are smashing shop windows
Needless to say, the progressive aspect does not reflect the length of an action, but the speaker’s view of a certain
event. Though aspect and the duration of an action are somehow related – in fact, to describe an event lasting
only a short time the simple aspect is more frequently used – the simple aspect is not reserved for short actions
nor is the progressive used exclusively to talk about events lasting for a (fairly) long time.
As we have seen above, the progressive aspect can combine with the perfective aspect, both
present and past, as well as with a modal or a modal and a perfective together. Finally, the infinitive can also be
used in the progressive:
Normally, only so-called dynamic verbs are used in the progressive, while stative verbs are
found in the simple aspect. Yet, stative verbs can sometimes occur in the progressive – when, for instance, they
refer to a situation which extends over time but is not permanent – while some dynamic verbs – those referring
to actions taking a very short time – usually occur in the simple form. Indeed, the difference between stative and
dynamic verbs is not so clear-cut as is often thought to be, and thus deserves to be examined in some detail. Such
difference is better conceived in terms of a continuum, and it would be more correct to talk about the stative or
dynamic senses in which a verb is used, though the traditional distinction between stative and dynamic verbs
is undoubtedly convenient (provided it is not applied in a simplistic way).
Stative verbs are verbs of “being”. Since they refer to “states”, they are normally used with the simple aspect.
On the contrary, dynamic verbs are verbs of “doing”, they refer to activities, events and processes. They can
occur in both the simple and the progressive aspects, depending on the meaning speakers wish to convey. The
first of the following sentences refers to a habitual, repeated action, the latter to an action in progress at the time
of speaking:
I work on Saturday morning
I’m working now
In general, two elements determine if a verb is frequently or rarely found in the progressive aspect: the length of
the action described by the verb and the status of the subject as either agent or experiencer. The progressive form
is common in clauses that have a human agent as subject and refer to an action, event, state or situation which
last for a substantial period of time; contrariwise, verbs that are rarely used in the progressive form describe
temporary states of short duration or actions that take place very quickly.
Stative verbs indicate possession and describe thoughts, beliefs, feelings, wishes, preferences, perceptions of
the senses, as well as states of being. Verbs that typically occur with stative senses are:
1) verbs of perception, such as: appear, feel, hear, see, seem, smell, sound and taste;
2) verbs that refers to mental, emotional and cognitive states, such as: adore, assume, believe, care, consider,
desire, detest, dislike, doubt, envy, expect, fear, find (meaning “consider”), forget, forgive, guess, hate, hear
(meaning “to be told”), hope, imagine, intend, know, like, love, mean, mind, notice, prefer, realize, recall,
recognize, refuse, regard, regret, remember, see (meaning “understand”), want, wish, wonder;
3) verbs that contain the idea of “being” and “having”, that refer to situations which cannot easily be imagined
as having a time limitation: be, have (meaning “possess”), belong, compare (meaning “be similar to”), concern,
consist, contain, cost, depend, deserve, differ, equal, exist, fit, hold, include, interest, involve, lack, matter,
measure, need, owe, own, possess, remain, require, resemble, suit.
The progressive aspect is unacceptable with stative verbs describing qualities – i.e. (relatively) permanent and
inalienable characteristics/properties of the subject referent – as different from states, which refer to less
permanent situations and thus can occur in the progressive:
They own a beautiful country house / *They are owing a beautiful country house
She has wonderful eyes / *She’s having wonderful eyes
Most stative verbs are not incompatible with the progressive aspect, though. When used in the progressive form,
these verbs are reclassified, and a change of interpretation takes place. They may refer to an action/situation or
behaviour that has limited duration:
He is not an honest man; I’m sure he’s not being honest with you
I love music; I’m loving the music tonight
That car costs quite a lot; This night out is costing me a fortune:
Stative verbs can also take the progressive form when the idea of an uncompleted physical or mental state is
emphasized. Furthermore, verbs expressing attitudes or emotions may convey tentativeness if used in the
progressive (often the past progressive):
I’m hoping they will reconsider their decision
I’m forgetting all I have learnt at school
I was wondering if I did the right thing
Verbs referring to sensory perceptions are usually preceded by can/could. However, they can also be used in the
progressive, when emphasis is put on the process of perception:
The deliberate acts corresponding to the involuntary sensory reactions indicated by hear and see are expressed
through the verbs listen and look. On the contrary, feel, smell and taste refer to both voluntary action and
involuntary perception. Needless to say, verbs referring to voluntary actions can be found in the continuous
form:
I (can) hear what they say; I’m listening to what they are saying
I (can) see her; I’m looking at her
I felt / could feel a hand touching my shoulder; I’m feeling the quality of
the leather
I (can) smell gas; She’s smelling the flowers
I (can) taste cinnamon in the cake; He’s tasting the custard
When they refer to a temporary condition, verbs describing bodily sensation can be used in both the simple and
progressive form with hardly any difference in meaning:
My knee aches badly; My knee is aching badly I feel tired; I’m feeling tired
As we have already stated, dynamic verbs indicate activities, they do not describe events as a whole. They
can occur in both the progressive and non-progressive form. They include verbs indicating a temporary situation
or an activity having some duration (for example cook, jog, live, read, study, work):
Some dynamic verbs are punctual, i.e. they refer to events that have very little duration, and thus they generally
occur in the simple aspect. Examples of punctual verbs are break, close, hit, jump, knock, nod, and tap. When
used in the progressive, they often indicate the repetition of an action:
A punctual verb can also be used in the progressive aspect for emphasis. This could be the case, for instance,
when speakers see events in slow-motion, or when they want to focus on something which happened while
something else was going on, even though this latter is an action taking only a little time to be completed:
The first sentence refers to the repetition of a momentary act, to a series of blows delivered to the man; the
second would make sense, once again, if interpreted as a series of acts (the person performing the action is a
hotel doorman), or if reference is purposely made to the few seconds an act such as opening a door takes to be
completed. In a radio or television commentary about an important political meetings, for example, it would not
sound strange even to dwell upon the opening of the door of a Prime Minister’s residence.
Verbs indicating a change of state or position, such as: arrive, become, die, drown, grow, land, leave, stop, turn,
can be used in the progressive aspect. When this is the case they refer to the period of time leading up to the
change of state (which need not take place):
A few verbs can be used either in the simple or the continuous form with no significant
difference of meaning:
You look great / you are looking great
I feel depressed / I’m feeling depressed
Other verbs can be used in both aspects, but with a difference in meaning. Consider the
following examples:
I think you’re wrong (= believe); I’m thinking about what you said (= reflecting on)
She comes from France (= lives in); She’s coming from France (= travelling)
I see what you mean (= understand); I’m seeing her quite often (= meet)
This room looks really nice (= the verb refers to the appearance of the room); He’s looking at you (= he
has directed his eyes in your direction)
Your suitcase weighs too much (the verb refers to the weight of the suitcase); People at the check-in
desk are weighing his suitcase (= they are measuring how heavy the suitcase is) The rules apply to
everyone (= concern); We are applying for a trading licence (= make an application for)
I consider him to be the best in his field (= think); They are considering my application (= look carefully
at)
Would you mind if I borrowed your bike? (= object); Our friends are minding the bags (= take care of)
So, the progressive aspect describes activities or events in progress at a particular time, usually for a limited
amount of time.
The present progressive describes events that are currently in progress, or events that are going to take
place in the future and about which the speaker feels quite certain.
Past progressive verbs describe events that were in progress at an earlier time:
I was just coming back from Witham.
Well he was saying that he's finding it a bit difficult.
It is sometimes assumed that the progressive aspect occurs only with dynamic verbs that describe activities.
However, the progressive is also used with verbs that describe a situation or a state. In this case, the
progressive refers to the ongoing continuation of the state:
Chris is living there now.
I was sitting in my office smoking one of James's cigarettes.
Perfective aspect
The perfective aspect is used to refer to a state or action which has taken place before the time of speaking, as
well as to a state or action (or series of actions) occurring in a period of time we imagine as continuing until the
present or until a certain moment in the past (until now or until then), or that has just ended. Remember: the events
and situations referred to by the perfective aspect have some relevance to the time of speaking (the present in the
case of the present perfective, the past in the case of the past perfective, the future in the case of the future
perfective). The perfective aspect is also used to indicate the completeness of an action, to see events as a whole:
The present perfective is formed by have/has + past participle, the past and by had + past participle, while the
future perfective by will have + past participle:
I have had the same car for twelve years! It’s time to get a new one
I had lived in Paris for two years when I decided to come back home
We will have been together for ten years next month
The perfective aspect can combine with the progressive aspect, with a modal or with a modal and a progressive
together (examples of the first and third combination are also provided above); perfect infinitives are also to be
found:
I’ve been running
He had been watching TV all day
You should have done this more carefully
He must have been kidding
They seem to have liked the film
Note that the perfect progressive aspect indicates the possible incompleteness of an action. In the following
examples, it is not clear whether the action has been completed or not:
I’ve been repairing my bike (I may or may not have finished repairing the bike)
They have been cleaning their room for hours (they may or may not have finished
cleaning)

Every verb phrase either has simple aspect (the unmarked form), perfect aspect, progressive aspect, or perfect
progressive aspect.
Underline all verb phrases (finite and non-finite) in the sentences below.
Identify the aspect of each verb phrase: simple, perfect, progressive, or perfect
progressive.
There are three major meanings for simple present tense when it refers to present time:
It can describe a state that exists at the present time. You can see this meaning in 1 and 2. The state may
be temporary, as in 1, or it may last for a longer time, as in 2.
It can refer to a habitual action, as in 3 and 4. In these examples, simple present tense is used to refer to
an activity that is repeated on occasion, rather than to a state of being.
It can describe an action that is happening at the present time, as in 5 and 6.
In addition, simple present tense can sometimes be used to refer to past or future time.
We add s or es to the base form of the verb in the third person singular
I work
You work
He works
She works in an office
It works
We work
You work
They work
1 Permanent truths
We use the simple present for statements that are always true
Summer follows spring Gases expand when heated
3 Habitual actions
The simple present can be used with or without an adverb of time to describe habitual actions, things that happen
repeatedly
I get up at 7
John smokes a lot
We can be more precise about habitual actions by using the simple present with adverbs of indefinite frequency
(always never, etc ) or with adverbial phrases such as every day / sometimes stay up till midnight
She visits her parents every day
We commonly use the simple present to ask and answer questions which begin with How often…?
How often do you go to the dentist? - I go every six months
Questions relating to habit can be asked with ever and answered with e g never and sometimes not ever
Do you ever eat meat? - No I never eat meat
4 Future reference
This use is often related to timetables and programmes or to events in the calendar
The exhibition opens on January 1st and closes on January 31st
The concert begins at 7.30 and ends at 9.30
We leave tomorrow at 11.15 and arrive at 17.50
Wednesday, May 24th marks our 25th wedding anniversary
write/writing
If a verb ends in -e, omit the -e and add -ing. Other examples:
come/coming, have/having, make/making, ride/riding, use/using This rule does not apply to verbs ending in
double e: agree/agreeing, see/seeing; or to age/ageing and singe/singeing
run/running
A verb that is spelt with a single vowel followed by a single consonant doubles its final consonant. Other
examples: hit/hitting, let/letting put/putting, run/running, sit/sitting
Compare: e.g. beat/beating which is not spelt with a single vowel and
which therefore does not double its final consonant.
begin/beginning
With two-syllable verbs, the final consonant is normally doubled when
the last syllable is stressed. Other examples: for'get/forgetting, pre'fer/prefernng, up'set/upsetting Compare:
'benefit/benefiting, 'differ/differing and 'profit/profiting which are stressed on their first syllables and do not
double their final consonants.
Note 'label/labelling 'quarrel/quarrelling, 'signal/signalling and 'travel/travelling (BrE) which are exceptions to
this rule.
Compare: labeling, quarreling, signaling, traveling (AmE) -ic at the end of a verb changes to -ick when we add
-ing:
panic/panicking picnic'picnicking traffic/trafficking
lie/lying
Other examples: die/dying, tie/tying
Simple past tense is most often used to refer to past time. In fictional narrative and description, the use of simple
past tense is common for describing imagined past states and events:
The clock on the tower of St Michael-in-the-Moor chimed nine as he came
onto the road. The milkman's van was on the green; Mrs Southworth from
the Hall was at the pillar box, posting a letter. He walked on away from
the green and the houses up the bit of Jackley Road from which Tace Way
turned off.
In addition, simple past tense is sometimes used for a situation at the present time. In this case, the past tense
gives information about stance. It is usually used with verbs like think, wonder, and want. The clause refers to a
current state of mind, but the past tense conveys tentativeness and shows that the speaker is being polite:
Furthermore, in some types of dependent clauses, the simple past tense is used as the subjunctive, to show
hypothetical or 'unreal' conditions :
wait/waited
Verbs not ending in -e add -ed: e.g. ask/asked, clean/cleaned, follow/followed, video/videoed
stop/stopped
Verbs spelt with a single vowel letter followed by a single consonant letter double the consonant: beg/begged,
rub/rubbed
occur/occurred
In two-syllable verbs the final consonant is doubled when the last syllable contains a single vowel letter followed
by a single consonant letter and is stressed: pre'fer/preferred, re'ferlreferred- Compare: 'benefit/benefited,
'differ/differed and 'profit/profited which are
stressed on their first syllables and which therefore do not double their final consonants. In AmE labeled,
quarreled signaled and traveled follow the rule In BrE labelled quarrelled, signalled and travelled are exceptions
to the rule.
cry/cried When there is a consonant before -y, the y changes to / before we add ed eg carry earned deny denied
fry fried try tried Compare delay delayed obey obeyed play played, etc which have a vowel before -y and therefore
simply add -ed in the past.
/
You
He
She shut the suitcase
It sat on
We
You
They
A time reference must be given / had a word with Julian this morning
or must be understood from the context
/ saw Fred in town (i e when I was there this morning)
/ never met my grandfather (i e he is dead)
When we use the simple past, we are usually concerned with when an action occurred, not with its duration
.
Past habit
Like used to, the simple past can be used to describe past habits
I smoked forty cigarettes a day till I gave up
The past is often used with when to ask and answer questions:
When did you learn about it? - When I saw it in the papers
When often points to a definite contrast with the present:
/ played football every day when I was a boy
Other adverbials can be used with past tenses when they refer to past time, but can be used with other tenses as
well :
adverbs: I always liked Gloria
I often saw her in Rome
Did you ever meet Sonia?
I never met Sonia
adverbial clauses:
I met him when I was at college
as + adverb + as:
I saw him as recently as last week.
Exercises
Read the following textbook article. Pay special attention to simple past-tense verbs.
Over 100 years ago, people only dreamed about flying. The Wright brothers, Wilbur and
Orville, were dreamers who changed the world. Wilbur Wright was born in 1867 and
Orville was born in 1871. In 1878, they received a paper flying toy from their father.
They played with kites and started to think about the possibility of flight. When they were older, they started a
bicycle business. They used the bicycle shop to design their airplanes. They studied three aspects of flying: lift,
control, and power. In 1899, they constructed
their first flying machine—a kite made of wood, wire, and cloth. It had no pilot. Because of wind, it was difficult
to control. They continued to study aerodynamics.1 Finally Wilbur designed a small machine with a gasoline
engine. Wilbur tried to fly the machine, but it crashed. They fixed it and flew it for the first time on December
17, 1903, with Orville as the pilot. The airplane remained in the air for twelve seconds. It traveled a distance of
120 feet. This historic flight changed the world. However, only four newspapers in the U.S. reported this historic
moment.
The Wright brothers offered their invention to the U.S. government, but the government rejected their offer at
first. The government didn’t believe that these men invented a flying machine. Finally, President Theodore
Roosevelt investigated their claims and offered the inventors a contract to build airplanes for the U.S. Army.
December 17, 2003, marked 100 years of flight. There was a six-day celebration at Kitty Hawk, North Carolina,
the location of the first flight. A crowd of 35,000 people gathered to see a replica of the first plane fly.
The cost to re-create the plane was $1.2 million. However, it rained hard that day and the plane failed to get off
the ground. You can now see the Wright brothers’ original airplane in the Air and Space Museum in Washington,
D.C.
Read more about the Wright brothers. Underline the past tense verbs in the following sentences.
The Wright brothers lived in Dayton, Ohio.
1. Their father worked as a Christian minister.
2. The boys learned mechanical things quickly.
3. They loved bicycles.
4. They opened the Wright Cycle Company repair shop, where they repaired bicycles.
5. They started to produce their own bicycle models.
6. The first airplane weighed over 600 pounds.
7. They succeeded in flying the first airplane in 1903.
8. Wilbur died nine years later, of typhoid.4

5. buy groceries 11. send e-mail
6. use a phone card 12. read a newspaper
/ was
You were
He was
She was waiting
It was
We were
You were
They were
We can often use the simple past to describe the action in progress, but the progressive puts more emphasis on
the duration of the action, as in the second of these two examples:
While I fumbled for some money, my friend paid the fares
While I was fumbling for some money, my friend paid the fares.
Parallel actions
We can emphasize the fact that two or more actions were in progress
at the same time by using e.g. while or at the time (that):
While I was working in the garden, my wife was cooking dinner
Repeated actions
This use is similar to that of the present progressive:
When he worked here, Roger was always making mistakes
Polite inquiries
This use is even more polite and tentative than the simple past:
/ was wondering if you could give me a lift.
PAST SIMPLE VS PAST CONTINUOUS
Use
Do you want to express that the actions in the past happened one after another or at the same time?
If you want to express that a new action happened in the middle of another action, you need both
tenses: Simple Past the new action and Past Progressive for the action already in progress.
Colin played football yesterday. Yesterday at six o'clock, Colin was playing football.
Certain Verbs
The following verbs are usually only used in Simple Past (not in the progressive form).

9. When I (be) ------------------on my way home, I (see) ---------------------an accident.
10. I (not / understand) ------------------- what they (talk) ------------------------ about.
action that has taken place once, never or several times before the moment of speaking
Example: I have never been to Australia
I / you / we / they I have been speaking. I have not been speaking. Have I been speaking?
he / she / it He has been speaking. He has not been speaking. Has he been speaking?
Examples:
I have lived in Paris for five years. ( I still live in Paris )
He has worked in Berlin since he graduated from the university. ( He still works in Berlin )
Examples:
I lived in Paris for five years. ( I moved another city and now I am no living there )
He worked in Berlin after he graduated from the university. ( He found himself a new job and he isn’t working in
Berlin)
2. Present Perfect Tense is used to express finished events in someone’s life. ( if the person is still alive –
life experience )
Examples:
HOWEVER; Simple Past Tense is used to express finished events in someone’s life. (if the person is dead)
Examples:
3.Present Perfect Tense is used to express finished events that happened at an unspecified time in the past and the
impact of the event is now continuing. ( Past Event – Present Result )
Examples:
She has lost her wallet. ( She can’t find it and I have no money now )
HOWEVER; Simple Past Tense is used to express finished events. There is no result in the present.
Examples:
She lost her wallet yesterday. ( I canceled my cards and bought a new wallet yesterday- there is no result now )
Yesterday we could reach Paul by phone ( I don’t need to reach or call Paul now – there is no result now)
He went to the theater two hours ago. ( now he is at school – there is no result now)
4. Present Perfect Tense is used with unfinished time words ( this week, today,this year etc) . The period of time is still
continuing.
Examples:
We haven’t called him this week. ( “this week” is not over yet )
They have had several exams this month. ( “this month” is not over yet )
HOWEVER; SIMPLE PAST TENSE IS USED WITH FINISHED TIME WORDS ( yesterday, last week)
Examples:
ATTENTION:
Time words with “in the” and without “in the” have different meanings.
For example;
( last year- in the last year/ last week – in the last week / last month- in the last month )
“Last month” and “in the last month” have different meanings.
“Last month” means the month before now. It is considered a specific time, so it requires Simple Past Tense.
“In the last month” means from 30 days ago until now ( at some point between 30 days ago and now ) . It is not
considered a specific time, so it requires Present Perfect Tense.
Examples:
We haven’t received any mail in the last month.
We didn’t receive any mail last month.
I have solved many problems in the last year.
I solved many problems last year.

Past perfect
Time up to a point in the past
We use the past perfect simple (had + past participle) to talk about time up to a certain point in the past.
She'd published her first poem by the time she was eight.
We'd finished all the water before we were halfway up the mountain.
Had the parcel arrived when you called yesterday?
We can use the past perfect to show the order of two past events. The past perfect shows the earlier action and the past
simple shows the later action.
It doesn't matter in which order we say the two events. The following sentence has the same meaning.
The thief had escaped when the police arrived.
Note that if there's only a single event, we don't use the past perfect, even if it happened a long time ago.
The Romans spoke Latin. (NOT The Romans had spoken Latin.)
We can also use the past perfect followed by before to show that an action was not done or was incomplete when the
past simple action happened.
Adverbs
We often use the adverbs already (= 'before the specified time'), still (= as previously), just (= 'a very short time before
the specified time'), ever (= 'at any time before the specified time') or never (= 'at no time before the specified time')
with the past perfect.
Put the verbs into the correct form (past perfect simple).

'd decided
2. I looked at the photo and suddenly realised that I ___ that man somewhere before.

The Past Perfect Continuous is formed with had been + present participle
We had been waiting for two hours before they arrived.
Had you been waiting for more than two hours before they arrived?
We had not been waiting for two hours before they arrived.
1 Duration before a past event/action
We use the Past Perfect Continuous to show that something stared in the past and continued to a point in the
past. The Past Perfect Continuous has the same function as the Present Perfect Continuous except that the
action doesn't continue to the present time but stops before something else in the past.
They had been waiting for an hour before we arrived.
She had been working at that trading company for five years before she moved to their rival company.
How long had you been trying to contact Sarah before you gave up?
How long were you studying medicine before you dropped out?
2 The result of a past action
The Past Perfect Continuous before an action in the past shows the reason for a result.
Peter was tired because he had been working for more than eighteen hours.
He failed the test because he had not been studying.
I had been playing tennis for five years before the injury.
Past Continuous or Past Perfect Continuous
Without a phrase like 'for an hour' or 'since March' it is possible to use the Past Continuous instead of the Past
Perfect Continuous but this can change the meaning of the sentence.
Peter was tired because he was working hard. This sentence shows that Peter was tired because he was
working at that moment.
Peter was tired because he had been working hard. This sentence shows that Peter was tired as a result
of working hard. It is possible that he continued working but the tense implies that he had just stopped.
Adverbs such as; always, only, never etc. are placed after the auxiliary 'had' and before the present participle.
I had never seen snow before 2012.
Had you really never seen snow before 2012?

There are nine central modal verbs in English: can, could, may, might, must, should, will, would, and shall. Modals have
several distinctive characteristics:
Semi-modals (also called 'periphrastic modals' or 'quasi-modals') are multiword constructions that function like modal
verbs: (had) better, have to, (have) got to, ought to, be supposed to, be going to, used to. In orthographic
representations of the spoken language, better, gotta, and gonna often occur as the reduced forms of had better, have
got to, and be going to.
Semi-modals express meanings that can usually be paraphrased with a central modal verb. For example: I have to read it
again. (CONV) <paraphrase: I must read it again.>
Mosquitoes aren't supposed to be inside here. ( c o w ) <paraphrase: Mosquitoes should not be inside here.>
In addition, some semi-modals are fixed expressions, which cannot be inflected for tense or person. However, some of
the semi-modals, like have to and be going to, can be marked for tense and person:
past tense:
He had to call the police.
third-person agreement:
Maybe she has to grow up a bit more.
These semi-modals can sometimes co-occur with a central modal verb or another semi-modal, underlined in the
examples:
There are also some lexical verbs and adjectives that have meanings similar to modal auxiliaries, in that they express
stance meanings, but they are neither idiomatic nor fixed expressions. Rather, these verbs and adjectives express their
core lexical meanings of desire, obligation, possibility, etc. Examples are: need to, dare to, want to, be able to, be obliged
to, be likely to, be willing to.
There will be no outcry from the corporate sector about the disarray in the accountancy profession.
(NEWS)
In addition, it is possible to group the central modals (except must) into pairs with related meanings that sometimes
distinguish between past time and nonpast time:
Modals and semi-modals are grouped into three categories based on their meanings and each category
contains both personallintrinsic and logical extrinsic meanings. (The semi-modal used to is excluded from
these categories, being the only modal that refers primarily to past time.)
The permission/ possibility / ability modals
The obligation/necessity modals and semi-modals
The volition/prediction modals and semi-modals
Be going to and used to
Modals with perfect aspect
Modals with progressive aspect
Each modal verb can express personal meanings or logical meanings: The permission/possibility
modals can also express 'ability'.
Underline all modal and semi-modal verbs in the sentences below.
For each one, identify the specific meaning. If the meaning is ambiguous, write both possibilities.
1 If possible the crop should be lifted when the ground is reasonably dry.
2 We're building a machine right now. The machine should be finished in six months.
3 You may build a bead stick only when you have the dice.
