过去式的构成（一般过去时全面讲解）
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。
例如：I saw him in the street yesterday. 昨天我在街上看见他了。
一般过去时的结构
1、肯定形式:主语+动词过去式+其他
例句：She often came to help us in those days.
2、否定形式：①was/were+not；②在行为动词前加didn't，同时还原行为动词
例句：I didn't know you like coffee.
3、一般疑问句：①Did+主语+谓语动词原型+其他？②WasWere+主语+表语?
例如：-Did you go to Beijing last week?
-Yes, we did. (No, we didn't.)
4、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？
例如：-What did you do last night?
-I did my homework.
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（辅元辅结构），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。
