考点一:考查基本概念 例 Both his parents look sad .Maybe they______what's happened to him . A.knew 简析:现在完成时主要强调过去发生的动作对现在造成 的影响,或过去发生的动作还未结束,一直持续到现在或将 来,重点在于对现在的影响。这种考查难度较大,往往无时 间状语,需要从上下文分析、推理才行。故上两侧根据上下 文分析、推理,正确答案是B。 考点二:考查时间状语 例1. He has A.already 例2. A.just 例3.The famous writer _____ one new book in the past A.is writing B.was writing C.wroteD.has written 例4.—Our country —Yes . I hope it will be even ______ . A.has changed;well C.has changed; better 例5.Zhao Lan ______already two years . A.was;studying 例6.We ______ Xiao Li since she was a little girl. A.know B.had known C.have knownD. knew 例7.Harry Potter is a very nice film.I______it twice . A.will seeB.have seenC.sawD.see 简析:现在完成时的时间状语常有如下四类: ⑴现在完成时常与already(已经)just(刚刚,正好) ever(曾经),never(从来,也不;从不)before(以前) yet(仍然)等连用。故例1应选B;例2应选C。 ⑵现在完成时常与recently(近来),so 前为止),in 语连用。因为上述短语表示的是从现在起往前推算的一段时 间,句中的动作是从过去某一时间或时刻开始持续到现在的。 故例3应选D,例4应选C。 ⑶现在完成时时常与“for +时间段或since +过去时间 点”连用(含从句,从句过去时)。故例5应选C,例6应选C。 ⑷现在完成时还与once(一次),twice(两次), three 复次数的词语连用。故例7应选B。 考点三:考查与一般过去时的区别 例1.—These farmers have been to the United States . A.will they go C.do they go 例2.—______ you ___ your —Yes . I _____ A.Did;do;finished C.Have;done;have finished 简析:现在完成时与一般过去时容易混淆,就是因为它们 所表示的动作都发生在过去,但二者又有区别:一般过去 时表示过去某个时间发生的事、存在的状态或经常发生的 动作,说话的侧重点在于陈述一件过去的事情,与现在没 有关系;现在完成时表示与现在有关系的发生在过去的动 作,它不与表示过去的时间状语(如yesterday,last week, a moment 考点四:考查非延续性动词的用法 例1. His A.joined B.has joined C. was in D.has been in 例2.—Do you know him well ? — A.were B.have been C.have becomeD. have made 例3.—How long have you —About two months . A.been B.gone 例4.Hurry up!The play __________ for A.has begun C.has been on 例5.His uncle died two years ago.(改变句子,句意不变) His uncle has 例6.Her mother has been a Party member for three years .(同义句) Her mother_______the 例7.It _____ten years since he left the army . A.is B.has C.will 简析:现在完成时中,非延续性动词不能与for和since引导的 表示一段时间的状语连用,通常是用相应的延续性动词来代替。 常用的非延续性动词及替代形式如下: close—→be get up—→be up, marry—→be married(to), fall asleep/ go to sleep —→be asleep ( sleep ) , get to know—→ know come/arrive—→be here/in , come/get back—→be back , go/leave-be away , buy—→have , die—→be dead , catch a cold—→ have a cold等, 故例1、2、3、4的正确答案依次为:D、B、A、C。例5应填 been 示,故例6应填joined;ago。再次,还可用“It is + 一 段时间+since从句”来表示,故例7应选A。 考点五:考查词组have/has 例1.Miss Green isn't in the office.she______to the A.has goneB.went 例2.My parents ______Shandong for A.have been in C.have 简析:“have/has (还未回来)",指主语所指的人不在这儿.“have/has 状语连用.“have/has been to +地点”表示“曾经去过某地 (但现在已不在那儿)。”故例1、2的正确答案皆为A。 现在完成时专项练习 一、用所给动词的适当形式填空。 1.I___already____(see)the film.I___(see)it last week. 2.__ he ____(finish) his work today ?
