5、be discussed. 这条规定仍需讨论。She has a strong accent of an American. 她带有浓重的美国口音。3以here，there等开头的句子，说明正在发生的动作，谓语动词不用进行时，而用一般现在时。Look out！There comes a fierce dog. 小心,来了条凶狗。Listen！There goes the first bell. 听，预备铃响了。4表示动作意义的动词，必须是习惯性的，经常性的动作或是一般性的行为才能使用一般现在时，而这种动词在现在进行时中则往往表示现在或现阶段正在进行的动作。Light travels much

It looks really nice.我正在看毕加索的画，它看起来太棒了。The police dog is smelling the trace of the thief. 警犬正在嗅小偷的踪迹。6在时间，条件状语从句中，将来的动作须用一般现在时来表示。If you

They watch TV in the evening. 10.What are you doing ?.一般过去时的用法：1过去某个特定时间发生，并且一下子就完成了的动作（即：非持续性动作），也可以表示过去习惯性的动作。一般过去时不强调动作对现在的影响，只说明过去。 I had a word with Julia this morning. 今天早晨，我跟朱丽亚说了几句话。 He smoked

19、many cigarettes a day until he gave up. 他没有戒烟的那阵子，烟抽得可凶了。 一般过去时常与表示过去的时间状语或从句连用，过去时间状语如：yesterday, two days ago（两天前）the other day（前几天），last week / year, in 1993, just now（刚才）、in the old days（过去的日子里） at that time, once, during the war, before, a few days ago, when引导的时间状语从句等。 句子中谓语动词是用一般过去时还是用现在完成时，取决

20、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 not(wasnt) / were

21、 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：Did+主语+动词原形+其它？肯

22、定回答：Yes，主语+did. 否定回答：No，主语+didnt. 如：Did they watch TV last night ? 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。重读闭音节单词需双写最后一个辅音字母再加-e

23、d。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 umbrella.彼得太太老

24、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，要特别注意！ I didnt know

25、 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. Does Li ming study

26、 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.eat-_ 15.drink-
