小学英语语法:介词

  1、介词是一种虚词。不能单独作句子成分,它只有跟它后面的宾语一起构成介词短语,才能在句子中起作用。
  
  有:in, on, under, with, behind, about, near, before, after, for, to, up, down, from, in front of, out of, fromto, at the back of
  
  2、表示时间的介词有:at,on,in。
  
  (1)at表示在某一个具体的时间点上,或用在固定词组中。如:at ten oclock, at 9:30 a.m., at night, at the weekend
  
  (2)on表示在某日或某日的时间段。如:on Friday, on the first of October, on Monday morning
  
  (3)in表示在某一段时间(月份、季节)里。如:in the afternoon, in September, in summer, in 2005
  
  3、in一词还有其他的固定搭配,如:in blue(穿着蓝色的衣服),in English(用英语表达),take part in(参加)。
