1、新概念 2 知识点总结第一部分、时态总结一、一般过去时;一、定义。1. 表示过去的动作或状态,常和明确的过去时间状语连用,如:yesterday, last week, three days ago, in 1998,just now 等,或与由 when引导的从句连用。2. 也可以表示过去某一段时间内经常或反复出现的动作。句子中常带有every day, often, usually, always, sometimes等时间状语。例:When I worked in the company, I got up early every morning. 在那家公司上班时,我每天早晨都起得很早
2、。In the past few years she usually went touring during her summer holidays. 在过去的几年里,每逢暑假她总是出去旅游。二、一般过去时态句子结构1 Be 动词的一般过去时态在没有实义动词的句子中使用be动词, am is 的过去式为 was; are的过去式为were. 如:I was late yesterday. We werent late yesterday. She wasnt a teacher three years ago. Were you ill yesterday? Were they once yo
3、ur classmates? -Yes, I was. -No, I wasnt. Who were your best friends in your primary school? 2. 实义动词的一般过去时态肯定句要使用动词的过去式,否定句和疑问句要使用助动词do和 does 的过去式 did. 如:I went home at nine oclock yesterday. I didnt go home yesterday. He didnt tell me about you. Did you go home yesterday?-Yes, I did. -No, I didnt.
4、When did you finish your homework last night/the day before yesterday? 3. 助动词和情态动词过去式如下:shallshould (将要)用于第一人称单数willwould(将要)用于所有人称can could (能,会)maymight(可以)mustmust (必须)have tohad 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。) 精选学习资料 - - - - - - - - -

6、ped 5) 不以 ed 结尾的过去式,称为不规则动词,如:write(写)-wrote go-went do-did have-had see-saw take-took make-made come-came buy-bought 技巧:巧记一般过去时:【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
7、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
8、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 waswere ” ;否定回答用“ No,主语 wasntwerent ” 。例如: Were Wei Hua and Han Mei here just now 刚才魏华和韩梅在
9、这儿吗?Yes, they were (No, they werent) 是的,她们在。(不,她们不在。)练习一、用 be动词的适当形式填空1I _ an English teacher now. 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 2 页,共 43 页2She _ happy yesterday. 3They _ glad to see each other last month. 4Helen and Nancy _ good friends. 5The little dog _ two years old this year. 6
