文档简介
1、 We have had four texts this semester.6. have been to和 have gone t o的区别-She has gone to the hospital. -她- 去医院了。 He has already obtained a scholarship.I havent seen much of him recently (lately).We have seen that film before. I have used this pen only three times. It is still good.George has met that
2、 gentleman several times.3. 现在完成时还往往可以同包括现在时间在内的时间状语连用如 up to these few days/weeks/months/years, just, up to,present(now), so far 等:Peter has written six papers so far.Up to the present everything has been successful.三 当现在完成时与表示短时间的时间状语连用时,谓语动词必须使用延续性动词。 如果谓语动词是非延续性动词则转化为对应的延续性动词。 若不是和短时间连用,则不用转化。英语
3、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。1. 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。2. 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 to,ente
4、r, 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3. 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 joinedShe has been up for quite some time. (她起床已有好
5、久了。)不用 has got upHas 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 1、close be closed1 4、turn on be on六 现在完成时的反义疑问句的结构 七 现在完成时考点例析一致,又后句的主语为 her parents 是复数 ,故选D 。B. Have; surfed; surfed 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
6、_the CD player for two weeks.A. has lent B. has borrowed 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
7、B。三、考查 have/has been (to, in)/have/has gone (to)的区别 。如:1. -Have you ever_Lintong to see the Terra Cotta Warriors? -Yes, I have.A. went toB. 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 bee
8、n 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,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。故参考答案为: Suns aunt has been there for ten years. /Suns
9、 aunt went there tenyears ago. /Its ten years since Suns aunt went there.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.
10、 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含意,故选C。现在完成时的练习(一)一、1、Both his parents look sad.
