II.
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。
III.
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
yesterday.
他昨天去玩具店了。
否定句结构为:主语
+did 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 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.
一般过去时口诀
一般过去时并不难,表示过去动作、状态记心间。
动词要用过去式,时间状语句末站。
否定句很简单,
didn't
站在动词原形前,其它部分不要变。
一般疑问句也好变,
did
放在句子前,主语、动词原形、其它部分依次站。
特殊疑问句也简单,疑问词加一般疑问句记心间。
最后一条请注意,动词过去式要牢记。
