1、新课标人教版英语必修1_2必背知识点三、现在完成时考点例析 现在完成时是较难掌握、中考考查较多的时态。涉及的考点有: 一、考查其构成 助动词have (has) +动词过去分词构成现在完成时。如: 1. Kates never seen Chinese films，_ ? A. hasnt she B. has she C. isnt she D. is she 析:陈述句部分含否定词never,简略问句部分要用肯定式，又因Kates是Kate has的缩写，故选B。 2. His uncle has already posted the photos to him. (改为否定句) His
2、uncle _ posted the photos to him _. 析:already常用在肯定句中，yet常用在否定句、疑问句中，故填hasnt, yet。 3. -Ann has gone to Shanghai. -So _her parents. A. has B. had C. did D. have 析:so+助/系/情态动词+主语结构中的动词形式应与前句结构中动词形式保持一致，又后句的主语为her parents是复数,故选D。 二、考查其用法与标志词 (一)当句中有never, ever, just, already, yet, before等时，常用现在完成时。如: 1.
3、 -Mum, may I go out and play basketball? -_you_ your homework yet? A. Do; finish B. Are; finishing C. Did; finish D. Have; finished 2. -_ you _anywhere before? -Yes, but I cant remember where I_ A. Did; surf; surfed B. Have; surfed; surfed C. Did; surf; have surfed D. Have; surfed; have surfed 析:据ye
4、t和before可知,应用现在完成时，故1题选D，2题选D。 (二)当句中有for +段时间或since +点时间等时，主句常用现在完成时，谓语动词必须是延续性动词，若是非延续性动词，要改为延续性动词或表状态的词(短语)。如: 1. His brother has been to Stone Forest twice_he came to Yunnan. A. after B. before C. since D. for 析:主句用的是现在完成时，而从句用的是一般过去时，故选C。 2. Tom_the CD player for two weeks. A. has lent B. has b
5、orrowed C. has bought D. has had 析:A、B、C均为非延续性动词，在肯定句中不与表段时间的短语连用，故选D。 3. I_a letter from him since he left. A. didnt receive B. havent got C. didnt have D. havent heard 析:据since可知，应排除A、C，hear from sb.=receive/get/have a letter from sb.意为收到某人的来信，故选B。 三、考查have/has been (to, in)/have/has gone (to)的区别。
6、如: 1. -Have you ever_Lintong to see the Terra Cotta Warriors? -Yes, I have. A. went to B. gone to C. been in D. been to 析:据句中的have，排除A，B项意为去某地了，C项意为一直呆在某地，D项意为去过某地，符合题意，故选D。 2. My parents _ Shangdong for ten years. A. have been in B. have been to C. have gone to D. have been 析:本题句中有for+段时间结构，据此可排除C，
7、B项意为去过某地，不合题意，D项缺介词，故选A。 四、考查现在完成时与其他时态的联系和区别。如: 1. Suns aunt has gone there for ten years.(改成正确的句子) 析:非延续性动词与段时间连用时，除了把非延续性动词改成延续性动词外，还可把动词改为一般过去时或借助句型Its +段时间+since+从句进行句子转换。故答案为:Suns aunt has been there for ten years. /Suns aunt went there ten years ago. /Its ten years since Suns aunt went there.
8、 2. Susan has been in this city for more than ten years.(改为同义句) _more than ten years _Susan _to this city. 析:据上题分析，且since引导的从句要用一般过去时，故填It is, since, came。 3. I wont go to the concert because I _my ticket. A. lost B. dont lose C. have lost D. is coming 析:因我丢了票的动作发生在过去，而且对现在造成了我不能参加音乐会的结果，符合现在完成时所表示的
9、含意，故选C。 英语的行为动词有持续性动词和瞬间性动词之分，使用中应注意两者的区别。 一、持续性动词: 表示一个动作可以持续一段时间或更长时间。 常见的study, play, do, read, learn, drive, write, clean , sleep, speak, talk, wait, fly, stay, sit, stand, lie, keep等。 二、瞬间性动词: 表示一个动作发生在一瞬间，非常短暂。亦称终止性动词。 常见的-begin, start, finish, go, come, leave, find, get up, arrive, reach, get
10、 to, enter, hear, stop, open, close, become, buy, borrow, lend, happen, join, lose, renew, die, take away, put up, set out, put on, get on/off等 瞬间性动词在完成时中如要与表示持续一段时间的状语连用，通常有两种方法: (1)用意思相当的持续性动词来替换 He has been in the army/a soldier for three years. (他参军已有3年了。)不用has joined She has been up for quite s
11、ome time. (她起床已有好久了。)不用has got up Has your brother been away from home for a long time? (离家已有好久了吗,)不用has left 常用瞬间动词相应持续性动词关系: 1、gobe away 2、comebe here 3、come backbe back 4、leavebe away(be not here) 5、buyhave 6、borrowkeep 7、diebe dead 8、beginbe on 9、finishbe over 10、openbe open 11、closebe closed 12
12、、losebe lost 13、get to knowknow 14、turn onbe on 15、get upbe up 16、sit downsit/beseated 17、joinbe in()或be amember 18、becomebe (2)用it issince结构来替换瞬间动词 例如:电影已经开映5分钟了。(两种方法) (1)The film has been on for five minutes. (2)Its five minutes since the film began. 他离开上海已有3天了。(两种方法) (1)He has been away from Sha
13、nghai for three days. (2)It is three days since he left Shanghai. 这本书我还给图书馆已有两周了。(一种方法) Its two weeks since I returned the book to the library. 他找到他妹妹已有多久了,(一种方法) How long is it since be found his sister? 4、瞬间动词的否定形式可以与表示一段时间的状语连用 例如:I havent seen you for a long time.(好久没见到你了。) Unit 1 Great scientis

42、。同时对方式状语从句也应引起重视。 一、时间状语从句 表示时间的状语从句可由when， as， while， whenever， after， before， till (until)， since， once， as soon as (或the moment )， by the time， no sooner than， hardly (scarcely) when， every time等引导。 e.g. When I came into the office， the teachers were having a meeting. He started as soon as he rec
43、eived the news. Once you see him， you will never forget him. No sooner had I gone to bed than I went to sleep. 二、原因状语从句 原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because， since， as ， now that(既然)等，for 表示因果关系时(它引导的不是从句)为并列连词，语气不如because强。 e.g. He is disappointed because he didnt get the position. As it is rainin
44、g， I will not go out. Now that you mention it， I do remember. 三、地点状语从句 引导地点状语从句的连词是where 和wherever等。 e.g. Sit wherever you like. Make a mark where you have a question. 四、目的状语从句 引导目的状语从句最常用的词(组)是so， so that(从句谓语常有情态动词)， in order that， in case(以防，以免)等。 e.g. Speak clearly， so that they may understand y
45、ou. She has bought the book in order that she could follow the TV lessons. He left early in case he should miss the train. 五、结果状语从句 结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that(从句谓语一般没有情态动词)， so that， such that等引导。 e.g. She was ill， so that she didnt attend the meeting. He was so excited that he could no
46、t say a word. She is such a good teacher that everyone admires her. 六、条件状语从句 条件状语从句分真实性(有可能实现的事情)与非真实性(条件与事实相反或者在说话者看来不大可能实现的事情)条件句。引导条件状语从句的词(组)主要有if， unless， so (as) long as， on condition that， so (as) far as， if only ( = if )。注意:条件从句中的if 不能用whether替换。 e.g. If he is not in the office， he must be out for lunch. You may borrow the book so long as you keep it clean. So far as I know(据我所知)， he will be away for three months. You can go swimming on condition that ( = if ) you dont go too far away from the river bank.
