巧记动词过去式

巧记动词过去式（一）be用was或用were, have, has变had.一般动词加-ed, 若是特殊得硬记。事情发生在过去，经常、反复或连续。时间可长也可短，动词时态用“过去”。（二）动词一般过去时，表示过去发生事。谓语动词过去式，过去时间作标志。否定句很简单，主语之后didnt添，疑问句也不难，did放在主语前。如果谓语之前有did,谓语动词需还原动词若是was, were，否定就把not添。巧学动词be的一般过去式掌握动词be的一般过去时口诀。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；否定句结构是三巧，not紧跟was / were；四是疑问句式巧，was / were向前跑（提前）。解释：【一巧】时间状语巧。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。例如：yesterday, last night / week /month /year, last Saturday, the day before yesterday, in 1998, five years ago等。【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.昨天早上我在教室里。He was at school last Tuesday。上周二他在学校。They were over there a moment ago.刚才他们在那边。【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.昨天我不在这儿。My parents were not（= werent）at home last Sunday.上周日我父母不在家。【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？这恰巧与动词be的一般现在时的疑问句式相似。例如：Were you at home the day before yesterday?前天你在家吗？Was she late this morning?今天早上她迟到了吗？更巧的是疑问句的答语也相似，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? 刚才魏华和韩梅在这儿吗？Yes, they were.（No, they werent.）是的，她们在。（不，她们不在。）从下列各题后所给的四个选项中选择最佳答案填空。（ ）1.My father _ ill yesterday.A. isnt B. arent C. wasnt D. werent（ ）2._ your parents at home last week?A.
