INTRODUCTION TO TENSES, ASPECTS, VOICES
TENSE is the relationship between the form of verb and time of
the action or state the past, present, or future time.
For example, "I study" is in the present tense, "I studied" is in the
past tense, and "I will study" is in the future tense.
We often use auxiliary verb BE and HAVE with other verbs
when we form different tenses.
ASPECT is the form of a verb which shows how the meaning of
a verb is in relation to time, typically expressing whether an
action is complete, repeated continuous.
For example, he dances is different from he is dancing in aspect.

VOICE refers to characteristics of verbs that differentiates
between the subject as performer of the action of the verb
(active voice) and the subject as receiver of the action of the
verb (passive voice).
The passive voice is formed with the auxiliary (to be + a past
participle) of either a regular or an irregular verb.
However, the participle can only be formed from a transitive
verb (verbs need objects.)

Verb forms
English verbs have five basic forms: the base form, the - S
form, the - ing form, the past form, and the past participle
form.
There are two types of past forms as regular and irregular
verbs.
The past form of regular verbs ends in - d, - ed, or - ied.
Regular verbs are predictable:
For regular verbs, normally add -ed.
Base form Past simple
work worked
walk walked
kill killed
Verbs that end in e just add d.
Base form Past simple
close closed
receive received
hate hated
One syllable verbs that end in one vowel and one
consonant double the final consonant and then add ed.

Asking questions
In English, information questions depend on using specific
words these are what we call WH question words.
We have nine WH question words: what, when, where,
which, who, why, whom, whose, and how.

These ask for information about time, place, reason, or
manner like: when, where, why, and how.
Adverbs describe a verb or an adjective.
Example: where did you read that? In this sentence, where is
asking from what source did the information come.
Other questions are formed with pronouns. These
ask about people or things.
They are five: what, which, who, whom, and whose.
