一般过去时 一般过去时的构成一般过去时是用动词的过去式来表示。? His words fetched a laugh from all present.? ? I did not sleep well last night.? Did you direct the tourist to the hotel?? be的一般过去时: be的过去时有四巧: 一是时间状语巧, 表示过去的短语要记牢; 二是形式巧,单数was,复数were; 三巧是否定句结构,not紧跟was/were; 四是疑问句式巧,was/were向前跑(提前)。 【一巧】时间状语(即标志词)巧。一般过去时表示过去发生的动作或存在的状态,恰巧 与表示过去的一些时间状语连用。 【二巧】形式巧。它与一般现在时一样,形式多样: 当主语是第一人称单数或第三人称单数时,谓语动词用was; 主语是第二人称或其他人称复数时,谓语动词用were。 例如: I was in the classroom yesterday morning. He was at school last Tuesday. They were over there a moment ago. 【三巧】否定句结构巧。 与动词be的一般现在时一样,它在动词后面加not即可变成否定句,并且was, were与not可以缩写成wasnt, werent。 即: 主语 + wasnt/ werent + 表语 + 其他 例如:I was not (=wasnt) here yesterday. My parents were not (=werent) at home last Sunday. 【四巧】 疑问句式巧。把was, were提到句首,句末用问号即可变为一般疑问句。 即: Was(Were) + 主语 +表语 + 其他? 例如: Were you at home the day before yesterday﹖ Was she late this morning﹖ 肯定回答用“Yes, 主语+was/were.”;否定回答用“No,主语+wasnt/werent.”。 例如:Were Wei Hua and Han Mei here just now﹖ Yes, they were. (No, they werent.) 一般过去时的用法? 一般过去时的基本用法? 表示过去某个特定时间发生的动作或存在的状态? 例如: He suddenly fell ill yesterday.?? The engine stopped because the fuel was used up.? 注意:在一般过去时的句子中,通常都要有表示过去的时间状语。?

He would sit for hours doing nothing.? c. 表示过去连续发生的一系列动作? 例如:She entered the room, picked up a magazine and looked through it carefully.? The students got up early in the morningand then read English aloud in the open air.? d. 在时间、条件状语从句中表示过去将要发生的动作? 例如:We would not leave until the teacher came back.?
