20、般过去时还是用现在完成时，取决于动作是否对现在有影响。如果句中带有确定的时间，只能用一般过去时，不用现在完成时。Have you had your lunch? 你吃过午饭了吗？（意思是说你现在不饿吗？） Yes, I have. 是的，我已经吃过了。（意思是说已经吃饱了，不想再吃了。） When did you have it? 你是什么时候吃的？（关心的是吃的动作发生在何时。） I had it about ten minutes ago. 我是大约十分钟以前吃的。 2.一般过去时谓语动词的构成：（1）be(was, were)作谓语. 否定句是在was/were后面加not，was no

21、t(wasnt) / were not (werent)。一般疑问句是把was / were提前并放到句首，首字母要大写。肯定句: She was at home yesterday.否定句: She wasnt at home yesterday.一般疑问句: Was she at home yesterday?（2）实义动词的过去式作谓语（不区分人称和数）肯定式：主语+动词过去式+其它。如：They had a good time yesterday.否定式：主语+did not(didnt)+动词原形+其它。如：They didnt watch TV last night.一般疑问句：D

Yes, they did. / No, they didnt.特殊疑问句：特殊疑问词+did+主语+动词原形+其它？如：What time did you finish your homework?3. 动词一般过去式的构成a.规则动词过去式的变化可速记为直、去、双、改四字诀。一般情况下在动词原形后直接加-ed。如：wanted，played。以不发音的字母e结尾的动词，去掉e再加-ed。如：hoped，lived。重读闭音节单词

23、需双写最后一个辅音字母再加-ed。如：stopped。以辅音字母+y结尾的动词变y为i，再加-ed。如：studied，worried。b.不规则动词变化，要逐一熟记。be动词过去式有两种形式，主语是第一、三人称单数形式使用was，其他人称用were。注意：1.在谈到已死去的人的情况时，多用过去时。2.表示过去一段时间内经常或反复的动作，常与always，never等连用。 Mrs. Peter always carried an umbrella.彼得太太过去老是带着一把伞。（只是说明她过去的动作，不表明她现在是否常带着伞。） 比较: Mrs. Peter always carries an

24、 umbrella.彼得太太老是带着伞。 （说明这是她的习惯，表明她现在仍然还习惯总带着一把伞） I never drank wine.我以前从不喝酒。（不涉及到现在,不说明现在是否喝酒） 3.如果强调已经终止的习惯时要用used to do He used to drink. 他过去喝酒。（意味着他现在不喝酒了。喝酒这个动作终止了） I used to take a walk in the morning.我过去在早晨散步（意味着现在不在早晨散步了） 4.有些句子，虽然没有表示过去确定时间的状语，但实际上是指过去发生的动作或存在的状态的话，也要用过去时，这一点，我们中国学生往往出错，要特别注

25、意！ I didnt know you were in Paris. 我不知道你在巴黎。（因为在说话时，我已经知道你在巴黎了。这句话指的是说话之前，所以只能用过去时表示。实际上，这句话暗指But now I know you are here.） I thought you were ill. 我以为你病了呢。（这句话应是在说话之前，我以为你病了。但是现在我知道你没病）辨别正误：Li Ming studied English this morning. （把此句变为一般疑问句）1.Did Li Ming studied English this morning？（,动词应该用原形）2. Doe

26、s Li ming study English this morning？（,时态应该用原句子的时态）3.Was Li Ming studied English this morning？（,应该用实义动词，而不是be动词）4.Did Li Ming study Enghish this morning？ （） 写出下列动词的过去式:1.go-_ 2.do-_ 3.have/has-_ 4.am/is-_ 5.are-_ 6.am not/isnt-_ 7.arent-_ 8.dont/doesnt-_ 9.study-_ 10.play-_ 11.see-_ 12.get-_ e-_ 14.
