2、 the past few years she usuallywent touringduringher summerholidays.在过去的几年里,每逢暑假她总是出去旅行;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 your class
3、mates? -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确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.When didyoufin
4、ishyourhomework lastnight/thedaybefore yesterday.3. 助动词和情态动词过去式如下:shall should (将要)用于第一人称单数willwould (将要)用于全部人称can could (能,会) may might (可以) must must (必需) haveto 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,后面的动词仍使用原形;如: I had to do my homework yesterday. 昨天我不得不做作业; 50三、一般过去时态动词变化形式一般过去时态由动词的过去式表示;大多数动词的过去式
5、是在动词原形后加上 ed 构成;这类动词称为规章动词;1) 一般情形下在词尾直接加ed;如: play playedworkworked2) 以 e 结尾的动词只加 d.如: like- likedloveloved3) 以辅音字母 +Y 结尾的动词,变 Y 为 I ,再加 ed.如: study studied carry carried4) 以重读闭音节结尾的动词,假如末尾只有一个辅音字母,要双写最终这个辅音字母,再加 ed.如: stop stopped5) 不以 ed 结尾的过去式,称为不规章动词 , 如:write (写) -wrotego-went do-did have-had
6、see-saw take-took make-made e-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;主语是其次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 th
7、ere 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:WasWere 主语 表语 其他?这恰巧与动词
8、 be 的一般现在时的疑问句式相像;例如: Were you at home the day before yesterday 前天你在家吗?Was she late this morning今日早上她迟到了吗?更巧的是疑问句的答语也相像,确定回答用“Yes,主语 waswere”;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;)练习一、用 be 动词的适当形式填空1Ian Engl

14、since+ 从句(过去时)E.g. Mary has been ill for three days.
