   1、一般过去时的概念:


  一般过去时表示过去某个时间发生的动作或存在的状态。
  常和表示过去的时间状语连用。如:last year, yesterday等;
  也可表示过去经常反复发生的动作,常和often, always等频率副词连用。
  例如:
  ①I saw 1 him in the street yesterday. 昨天我在街上看见他了。
  ②Li Mei always went to school on foot last year. 去年李梅总是步行上学。
  2、一般过去时的构成
  我们主要来学习谓语动词为实义动词的一般过去时的构成。
  动词过去式的构成:
  (1)规则动词过去式的构成有四条规则:
  ①一般在动词原形末尾直接加上-ed。如:look-looked。
  ②以不发音的字母e结尾的动词,去e再加-ed。如:live-lived。
  ③末尾只有一个辅音字母的重读闭音节,先双写这个辅音字母,再加-ed。如:stop-stopped。
  ④末尾是辅音字母+y结尾的动词,先变y为i,然后再加-ed。如:study-studied。
  (2)不规则动词的过去式需特殊记忆。
  如:am(is)-was, are-were, go-went, come-came, take-took, have (has)-had等。
  3、一般过去时的几种句型:
  肯定句结构为:主语+动词的过去式+其它。如:He went to the toy store 2 yesterday. 他昨天去玩具店了。
  否定句结构为:主语+did 3 not (didn't)+动词原形+其它。如:He didn't go to the toy store yesterday. 他昨天没去玩具店。
  一般过去时的一般疑问句的构成:Did+主语+动词原形+其它?如:
  1) -Did you go to Beijing last week?
  -Yes, we did. (No, we didn't.)
  2) -Did you meet the businessman 4 before?
  -No, I didn't. (Yes, I did.)
  一般过去时的特殊疑问句的构成:疑问词+did+主语+动词原形+其它?如:
  1) -What did you do last night?
  -I did my homework.
  2) -Where did you go last week?
  -I went to Shanghai with my parents.
