语法讲解
一般过去时 (The simple past tense)
一、定义:
1. 一般过去时表示过去发生的动作或存在的状态。常用的时间状语有:yesterday(昨天),the day before yesterday(前天),last night(昨天晚上),last year(去年),two days ago(两天前),just now(刚才),a moment ago(刚才),in the past(在过去)等以及由连词when等引导的时间状语从句。如:
1) We saw a wonderful film last week. 上周我们看了一个精彩的电影。
2) I wasn’t at home yesterday. 昨天我没在家。
2. 表示过去经常或反复发生的动作,可与often连用。如:
1) When I was a boy, I often went to play in that park. 当我是个孩子时,常去那个公园玩。
二、结构:主语 + 动词过去式
三、动词过去式的构成:
1. 直接加ed。如:worked,showed,reported,shouted,opened,played,waited,crossed。
2. 以e结尾的直接加d。如:lived,noticed,moved,changed,dived,used,stared。
3. 辅音 + y结尾的,把y改成i再加ed。如:hurry – hurried,carry – carried。
(元音 + y结尾的,直接加ed。如:played,enjoyed)
4. 重读闭音节,只有一个辅音字母结尾的,双写该辅音字母,再加ed。如:stopped,shopped,planned,travelled,preferred。(travel,prefer不双写也可以)
5. 不规则变化:需要逐一熟记。如:have—had,hear—heard,take—took。
(参考教材91页及123页)
四、-ed的读音:
1. 如果动词是以清辅音结尾,则后面的ed读成/t/。如:
jumped,stopped,liked,missed。
2. 如果动词是以浊辅音或元音结尾,则后面的ed读成/d/。如:
moved,used,showed,disappeared
3. 如果动词是以t或d结尾,则后面的动词读成/id/。如:
started,reported,collected,needed,ended,attended。
五、一般过去时的基本句型变化:
如果有be动词was和were,否定句在was和were后面加not,缩写为wasn’t和weren’t。一般疑问句将was,were提到句首;如果没有be动词,否定句则用did not,缩写为didn’t,一般疑问句则在句首加Did。did后面的实义动词要用原形。如:
1. I was late for school yesterday.
否定句: I wasn’t late for school yesterday.
一般疑问句: Were you late for school yesterday?
肯定回答: Yes, I was.
否定回答: No, I wasn’t.
划线提问: When were you late for school?
2. He had lunch just now.
否定句: He didn’t have lunch just now.
一般疑问句: Did he have lunch just now?
肯定回答: Yes, he did.
否定回答: No, he didn’t.
划线提问: What did he do just now?
