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。

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。

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。
