2、介绍1the Simple Present (一般现在时)一般现在时表示当前的状态以及经常习惯发生的动作。例如:1) The earth turns round the sun.(宇宙不变的真理)2) I get up at six every morning.(经常习惯发生的动作)3) We are Junior Three students.(表示当前的状态)2 . the Simple Past(一般过去时)一般过去时能够表示过去发生的动作或情况,在句子中往往有明确的表示过去的时间状语。例如:1) None of the football games had been more exci
3、ting than the one he watched yesterday.(句子中有yesterday这个明确表示过去的时间状语)2) last night I gave a lecture in the meeting hall.(last night表示过去的时间,所以我们也用一般过去时)一般过去时有时还能够表示过去习惯的动作。例如:1) When he was in the country, he liked to take a walk after supper.(句中liked表示他过去在农村市常常发生的动作)2) I used to go to work by bus.(use
4、d to 表示“过去常常”)3the Simple Future(一般将来时)一般将来时即表示将来某个时间要发生的动作或存有的状态,也表示将来经常发生的动作。例如:1) We are going to enter senior high school in the near future.(in the near future是一个表示将来的时间状语,所以用一般将来时,表示将来某个时间要发生的动作)2) There will be more and more foreigners in China.(本句表示将来经常发生的动作,意为:在中国会有越来越多的外国人)4the Present Con
5、tinuous Tense(现在实行时)现在实行时表示当前正在实行的动作,句子中往往有now,at present,these days等做时间状语。例如:1) We are learning eight tenses now.(我们用一般现在实行时,表示当前正在实行的动作)2) Listen! They are singing in the classroom.(句子中listen表示“听”,说明句中的动作正在实行之中,所以我们用现在实行市)5the Past Continuous Tense(过去实行时)过去实行时表示过去一个时间点或时间段中正在发生的动作。例如:1) We were ha
6、ving supper at six yesterday evening.(过去某一个时间点at six yesterday evening正在发生的动作)2) They were playing video games from 2 p.m. to 4 p.m. yesterday afternoon.(过去某一个时间段from 2 p.m. to 4 p.m. yesterday afternoon正在发生的动作)3) We were having an English lesson when Tom came in.(当过去某一个动作were having正在实行时,另一个动作came发
7、生了)6the Present Perfect Tense(现在完成时)现在完成时表示过去发生的动作对现在造成的影响与结果,或表示过去开始并持续到现在的动作或状态。例如:1)We have learned about eight tenses so far.(so far表示“至今为止”,常用于现在完成时)2)We have studied English for six years.(这里的for+时间段表示从过去开始并持续到现在的动作,用现在完成时)3)I have never met him since last month.(这里的since+时间点表示过去发生的动作对现在造成的影响与
8、结果,所以用现在完成时)7the Past Perfect Tense(过去完成时)过去完成时表示在过去某一个时间或动作前已经发生或者完成的动作,而且它常常用在宾语从句中。例如:1) By the end of last month, they had learned 2000 English words.(by the end of last month表示“到上一个周末为止,所以用过去完成时)2) After the boy had finished the homework, he watched TV.(finish这个动作发生在过去某一动作watched 之前,所以用过去完成时)8t
9、he Past Future Tense(过去将来时)过去将来时表示对于过去某一个时间而言将要发生的动作或存在的状态,它常用在宾语从句中。例如:1)He said we would win the game the next week.(这句句子里用过去将来时是因为said和the next week的关系)练习:.Fill in the blanks with the verbs in their proper forms:1.

20、sh class.2. 当动作的承受者是我们说话的中心时,或描绘一个过程或一个实验时,我们常用被动语态。例如:The design of the hotel was made by a young man.The milk will be put into the coffee in a few minutes.二、被动语态的结构被动语态形式 be +过去分词一般现在时 am/is/are +过去分词一般过去时 was/were +过去分词一般将来时 will be +过去分词现在完成时 has/have+been +过去分词现在进行时 am/is/are+being +过去分词过去进行时 w
21、as/were+being +过去分词过去完成时 had+been +过去分词过去将来时 would+be +过去分词情态动词 情态动词+be +过去分词三、如何将主动语态变为被动语态例句:We run that new restaurant.The new restaurant is run by us. 1 2 31. 变宾语为主语。2将谓语部分的主动形式改为被动形式。要注意:第一,时态一样;第二,谓语的单数和复数必须和主语一致。3By+原来的主语,但如果原来的主语是人称代词,则要用其宾格,因为by是介词,后须用宾格。4注意,有些动词后接的动词不定式作宾语补足语不接to,如:make, s
22、ee, watch等,当变成被动语态时,应该加上to.例如:I heard him sing two American songs.改为:He was heard to sing two American songs.练习:.Choose the best answer:( ) 1.

35、定语、状语和宾语补足语。动词不定式的形式是to +动词原形,但to有时要省去。动词不定式在具体运用时,用不用to,取决于谓语动词的用法:一.带to的不定式结构1.我们学过的能直接跟带to的不定式结构的动词主要有:want, ask, tell, hope, learn, try, decide, forget, remember, like ,love, stop, go, come等。2.动词不定式的否定形式是在不定式前直接加not,即not to do sth.。例如:Jim told me not to wake up Kate.吉姆告诉我别叫醒凯特。二不带to的不定式结构以下几种情况使
36、用不带to的动词不定式:1.在固定词组had better之后。注意:had better的否定形式是had better not do sth.。例如:You had better go home now.你最好现在回家。Its cold outside. Youd better not go out.外面很冷,你最好不要出去。2.在let,make,see, feel, watch,hear等感官或使役动词后,要跟不带to的动词不定式作宾语补足语。例如:I made them give me the money back.我迫使他们把钱还给我。I didnt see you come in
37、.我没看见你进来。3.在引导疑问句的why not之后。Why not+不带to的不定式是Why dont you do的省略,可以用来提出建议或劝告。例如:Why not go with us。为什么不和我们一起去呢。Why not take a holiday。=Why dont you take a holiday。为什么不休个假呢。三动词不定式作主语不定式结构作主语时,采用it作形式主语,而把不定式结构后置的形式。例如:It took us twenty minutes to get there.It is our duty to clean the room every day.四动
38、词不定式作定语不定式作定语,要放在它所修饰的名词或代词的后面。例如:I have nothing to say on this question.对这个问题我无可奉告。五动词不定式作宾语有的及物动词要求跟复合宾语(即宾语+宾语补足语)。如果其中的宾语是不定式短语,则必须将形式宾语it放在宾语的位置上,而将不定式短语(真正的宾语)放在宾语补足语之前。例如:I find it useful to learn English well.我发现学好英语很有用。We thought it wrong not to tell her.我们认为不告诉她是错误的。六动词不定式作宾语补足语动词不定式作宾语补足语
39、是动词不定式用法的一个重点,学习时要注意以下三种情况:1.作动词ask, like, tell等的宾语补足语时,动词不定式符号to不可以省略。例如:He asked me to talk about English study.他请我谈谈英语学习。2.作使役动词let, have, make以及感官动词feel, hear, see, watch等的宾语补足语时,动词不定式符号to要省略。例如:The teacher made him say the word like this.老师让他像这样说这个单词。3.作动词help的宾语补足语时,动词不定式符号to可以带,也可以不带。例如:Could
40、 you help me (to) carry the heavy box。你能帮我搬这个重箱子吗。七动词不定式作状语动词不定式及其短语具有副词的特性,可在句中用作状语。1.放在句首也可以放在句尾表示目的等。例如: He stopped to have a rest.他停下来休息。2.跟在作表语的形容词或过去分词的后面。例如:Im sorry to hear that.听到这事我感到很难过。3.用在too. to.结构中。例如:He is too young to understand all that.他太年轻了,不能理解这件事。八. 动词不定式作表语 例如:His job is to or
