                            PREPOSICIONES DE TIEMPO
 Las preposiciones utilizadas con relación al tiempo pueden resultar algo complicadas
   para aprender. Probablemente obtengas mejores resultados si te aprendes unos
                             cuantos ejemplos. Veamos...
                                    AT? IN? ON? BY?
AT se usa con las horas (at 10:00 am), momentos del día (at night) y con nombres de
                         festividades (at Christmas, at Easter).
  IN se refiere a partes o divisiones del día (in the evening), meses (in November),
 estaciones del año (in winter) y años (in 2004). IN se usa también para señalar un
              período en el cual algo tendrá lugar (in nine months' time).
 ON se usa para los días de la semana (on Monday), para partes o divisiones del día
(mencionando el día de la semana) (on Monday mornings) y para las fechas (on 15th
                                 May, on November 5th).
     BY indica el último momento/hora/fecha en que una acción será finalizada.
Normalmente es similar en significado a before. BY se usa generalmente con tiempos
                 futuros (I will have finished my project by Saturday).
                                    BETWEEN? AMONG?
           La regla básica, BETWEEN para 2 y AMONG para más de 2 generalmente es
efectiva. Sin embargo, si las dos cosas están mezcladas (variedades de flores, galletas,
   etc) se prefiere utilizar AMONG (She walked among the roses and dahlias). Por el
     cntrario, si hay pocas cosas y a éstas se las considera aisladamente, se utiliza
                  BETWEEN (She walked between the three mountains).
                                    TO? TOWARDS?
TO implica la idea de destino mientras que TOWARDS sólo implica dirección o sentido.
 Por ejemplo: He walked to the village, implica que él llegó allí. He walked towards the
 village, sólo implica que él caminó en esa direción, pero desconocemos si ha llegado.
                               FROM? OUT OF?
OUT OF es más específico que FROM y expresa "desde el interior". El opuesto de OUT
                      OF es INTO (He came into the house).
                                   OFF? OUT OF?
OFF expresa la idea de "bajar desde". Por este motivo, we get off a train, plane, ship,
bus or bicycle, pero we get out of a car or taxi. De modo similar, we get in/into a car
           or taxi, pero we get on/onto a train, plane, ship, bus or bicycle.
                                    IN? WITH?
 Usamos IN cuando nos referimos a lo que alguien está vistiendo (a man in black, a
woman in red). Por el contrario, usamos WITH para objetos que llevamos o portamos
(a man with an umbrella, a lady with a purse) y también para características físicas o
                          fisonómicas (a girl with red hair).
                    IN/AT THE BEGINNING? IN/AT THE END?
 Recuerda que decimos AT THE BEGINNING OF SOMETHING, pero simplemente IN
   THE BEGINNING: At the beginning of the book there is a long sentence; In the
beginning there was the title in red capitals. De modo similar, generalmente se dice AT
 THE END OF, pero sólo IN THE END: In the end Fanny marries her cousin who has
   been her secret passion since childhood; At the end of the film Fanny marries her
                                     cousin Edmund.
                                  IN TIME vs ON TIME
       ON TIME expresa punctualidad, no tarde o demora. IN TIME expresa lo
     suficientemente temprano para hacer algo o antes de que un acontecimiento
   desagradable ocurra. Por lo tanto, decimos: The hero arrived in time to save the
               children; It is important to arrive on time to an interview.
