Grammar 一般过去时

一、一般过去时:过去某个时间发生的动作或存在的状态。用动词的过去式来表示,用be(was,were)动词的过去式表示过去的状态。

二、通常使用一般过去时的时间状语

如:yesterday,the day before yesterday,two days ago…,the other day,this morning,

last night (week 、Sunday 、month、winter、year、),ago (一段时间+ago),

just now, at the moment ,at the age of ,one day ,once upon a time 、long long ago

三、行为动词的一般过去式

行为动词是指表示具体动作的动词,如play, watch, eat等,它们的过去式表示这个动作发生在过去的某一时间。 We played basketball yesterday.

1、行为动词的过去式的构成:可概括为“直、去、双、改”四字诀。

①一般情况下在动词原形后直接加ed. 如watched, played.

②以不发音的字母e结尾的动词,去掉e再加ed. 如hoped, lived.

③重读闭音节结尾且末尾只有一个辅音字母,须双写最后一个辅音字母,再加ed. 如stopped, dragged, dropped, planned, chatted, kidded, begged, regretted, controlled, admitted, occurred, preferred, referred, permitted, equipped等.

2.行为动词在一般过去时态的句子中的用法

(1)肯定句:谓语动词要用过去式时,行为动词的过去式没有人称和数的变化;

肯定句为:主语+动词过去式+宾语

如:I went home at nine o'clock yesterday. They watched TV last night.

②改为否定句时,要把谓语动词改为“didn’t+动词原形”;

否定句:主语+didn't +动词原形+宾语

如:I didn't go home yesterday. They didn’t watch TV last night.

③改为一般疑问句时,在句首加助动词did,句中的动词要改为动词原形。

一般疑问句:Did +主语+动词原形+宾语

如:Did you go home yesterday Did they watch TV yesterday 肯定回答:Yes,I did. Yes, they did.

否定回答:No,I didn't. No, they didn’t.

④特殊疑问句:特殊疑问词+一般疑问句

When did they go home When did they watch TV

四、be动词的一般过去时

1.be动词过去式的构成

①be动词的过去式表示过去的状态,如是什么,在哪里,怎么样等。

I was twelve last year.

②当主语是第一人称单数或第三人称单数时,谓语动词用was

③主语是第二人称或其他人称复数时,谓语动词用were.

2.be动词在一般过去时态的句子中的用法。

①在肯定句中:主语+was (were) +表语(在人称和数上与主语保持一致;)

如:I was late yesterday. They were in Beijing

last week.

②否定句:主语+was (were) +not+表语

如:We weren't late yesterday. They weren’t/ were not in Beijing last week.

③疑问句:Was (Were) +主语+表语

如:Were you ill yesterday Were they in Beijing last week

肯定回答:Yes,I was. Yes, they were.

否定句:No,I wasn't. No, they we ren’t.

④特殊疑问句:特殊疑问词+was (were) +主语+表语

shall―should(将要)用于第一人称单数will―would(将要)用于所有人称

can—could(能,会)may―might(可以)must―must (必须)have to―had to(不得不)

助动词和情态动词的过去时态要使用他们的过去式,后面的动词还使用原形。

如:I had to do my homework yesterday. (昨天我不得不做作业。)
