现在完成时1.构成现在完成时是由助动词have(has)+动词的过去分词构成。
助动词have(has)表明事情发生于现在。
它和主语的人称、数要保持一致。
过去分词在句子中做谓语,说明句子的含义。
2.用法(1)动作发生在过去某个不确定的时间,但对现在有某种影响和结果。
常被just、already、yet 等副词修饰。
如:-Have you had lunch yet? -Yes,I have. I've just had it.你(已经)吃午饭了吗?我刚刚吃过。
(现在我不饿了)(2)表示从过去某一时刻开始一直持续到现在的动作或状态。
这个动作可能刚停止,可能仍然在进行。
常带有for和since等表示一段时间的状语。
如:He has taught here since 1981他自1981年就在这儿教书。
(可能还要继续教)I have't seen her for four years.我有四年没见到她了。
(3)表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”,常带有twice,ever,never,three times等时间状语。
如:I have been to Beijing twice.我去过北京二次。
3.现在完成时的时间状语(1)现在完成时属于现在时范围,故不能和过去的时间状语连用。
如:yesterday,last Sunday,in1990,three years ago等。
但是,在强调动作产生的后果和影响时,可以和一些表示不确定的时间状语连用。
a. 用副词already和yet。
already一般用于肯定句中,yet一般用于否定句和疑问句中。
如:We have already finished our homework.我们已完成作业了。
They haven't finished their homework yet.他们还没有完成作业。
b.用ever 和never。

外研版英语八年级英语句型及语法(英语现在完成时)及答案解析百度文库一、初中英语现在完成时1.He ___________ for ten years.A. has been marriedB. marriedC. got marriedD. has married【答案】A【解析】【分析】在现在完成时态里,当出现for+段时间时,短暂性动词必须换成延续性动词。
get married需换成be married。
故选A。
【点评】该题考查的是对现完时态中的短暂性动词与延续性动词动词的掌握,这一块内容是中考的重难点,考试频率占时态考查题的一半以上。
学生必须牢记这两种词的转换及转换条件。
2.—Do you still play basketball?—Oh, no. I ____ it for the past two years.A. haven't playedB. didn't playC. won't playD. hadn't played【答案】A【解析】【分析】句意:——你还打篮球吗?——哦,不了。
我已经有两年没有打过了。
根据句中的for the last two years可知应与完成时态连用,又有时间是the last two years可知是从现在往前两年,因此应使用现在完成时态,故选A。
【点评】考查动词时态中的for+段时间与完成时态连用,根据时间确定是现在完成还是过去完成。
3.His cat has ________ for five weeks.A. diedB. been deadC. dyingD. dies【答案】 B【解析】【分析】句意:他的猫已经死了5个星期了。
die是短暂性动词,不能表示状态的延续。
由时间状语 for five weeks可知应用延续性动词,故答案选B。
【点评】考查现在完成时。
4.Great changes in my hometown in the last few years.A. took placeB. will take placeC. have taken placeD. have been taken place 【答案】C【解析】【分析】句意:过去几年我的家乡发生了巨大的变化。
英语现在完成时用法总结附答案一、初中英语现在完成时1.—— ______you _____ out the problem, Sam?——Not yet, but I'm going to.A. Did, workB. Are, workingC. Have, workedD. Will , work【答案】 C【解析】【分析】句意:萨姆,你计算出这道数学题了吗?——还没有,但是快了。
结合语境可知上文描述的是现在已经完成的动作,故用现在完成时态。
选C。
【点评】英语中的时态主要是借助于时间状语与上下文语境来进行判断。
解答此类题型,首先要注意句子中的时间状语,如果没有则要通过分析上下文,结合语境来判断句子的时态。
英语疑问句中一般具有时态上的对应关系,注意结合这一特点进行区分。
2.Mike used to be a top student, but he behind since he lost himself in computer games.A. fellB. has fallenC. wasD. has been【答案】 D【解析】【分析】句意为“Mike过去是尖子生,但自从迷上电子游戏以来成绩落后了”。
由since可知but后的主句用现在完成时,瞬间动词fall不能和since引导的时间状语从句连用,故用延续性动词be。
故选D。
【点评】本题考查现在完成时中非延续性动词和延续性动词的转换。
3.So far Tom with Mary _______ 50 left -behind children to do their homework after school.A. helpB. helpedC. has helpedD. have helped【答案】 C【解析】【分析】此题要掌握现在完成时的时间状语及主语+with 短语是单数的概念,即可得出答案。
选C。
4.—Do you miss your parents far away?—Yes, very much. They the hometown for over two years.A. leftB. have leftC. were away fromD. have been away from【答案】 D【解析】【分析】根据句意“他们已经离家两年多了”可知用现在完成时,时间状语for over two years 表示时间段,动词要具有延续性,left是 leave的过去分词,是短暂性动词,不能和时间段连用,故选D。
现在完成时一、结构:现在完成时由“助动词have (has) + 过去分词”构成。
其否定式是在助动词have/has后加not;一般疑问句是将助动词have/has移至句首。
若肯定句中有already,在变成否定句、疑问句时应将其改成yet。
eg. I have already posted the letter. (信已经不在我这儿了)Her friend has already posted the photos to him. (改为否定句和疑问句)He r friend _______ the photos to him _______. (hasn’t posted, yet)_______ her friend _______ the photos to him _______?(has, posted, yet)二、用法:1、表示过去发生的某一动作对现在造成的影响或结果,常与一些时间状语,如:already, yet, ever, never,just, before, once, twice等连用,也可以和包括现在在内的时间状语,如these days, today, this year, so far等连用.1)--- Who will go to the airport to meet Jenny?--- I will. I _______ her several times. I can find her easily.A. metB. have metC. had metD. will meet (B)2)It’s 7:30. I can’t believe you _______ cooking dinner yet, Sally.A. haven’t startedB. didn’t startC. don’t startD. hasn’t started(A)2、表示过去发生的动作或存在的状态,一直持续到现在,也许还将继续下去,可以和表示从过去某一时刻延续到现在的一段时间的状语连用,即for +时间段,since+时间点/从句, in the last ten years等,谓语只可用延续性动词.eg. Mr.Liu has lived here for five years.解析:(一)英语动词根据词义可分为两种,一种是延续性的,一种是终止性的,终止性动词(也可称为非延续性动词,瞬间动词,或点动词),如begin, start, die, buy, leave, come等,表示动作的发生与结束于一瞬间完成,不能再延续,所以它的现在完成时不能和表示延续的时间状语连用,即不能与表示一段时间的状语,for+时间段, since+时间点/从句连用,也不能用在how long引导的特殊疑问句中.eg. I've left Shanghai for three days.(×)I've been away from Shanghai for three days.( √ ).I left Shanghai three days ago. ( √ )It is /has been three days since I left Shanghai.( √ )(二)初中英语课本中常见终止性动词有:leave, go, come, arrive, begin, buy, borrow, die, join, become 等.终止性动词要表示持续时, 可用以下方法:⑴将时间状语改为时间段+ ago,句中谓语动词用一般过去时.eg. 我弟弟参军两年了. My brother joined the army two years ago.⑵若保留for+时间段,since+时间点/从句, 或用在how long 句型中,则需将终止性动词改为相应的状态动词或延续性动词. 常见终止性动词与延续性动词(或状态动词)的对应关系如下:open-----be open die------be dead close----be closed become---beborrow---keep begin/start-----be on put on----wear leave---be away (from) buy-----have fall asleep----be asleep end/finish-----be overcatch a cold-----have a cold come/go/arrive/get/reach/move------be in/atjoin the army----be in the army be a soldierjoin the Party----be in the Party be a Party member→My brother has been in the army for two years.→ My brother has been a soldier for two years.(三)Has been to和been in/at been to去过某地,表示某人的一种经历,可以和once ,twice, already, ever, never等连用.eg. She has been to Shanghai twice. (表示目前人在这里)has gone to 去某地了,说话时某人已离开此地,在去某地的途中或已在某地,eg. She has gone to Shanghai。
初中英语语法大全|现在完成时的结构和用法(练习附答案)(一)基本结构现在完成时的句子结构一般为:主语+have/has+过去分词+其他成分如:We have already had lunch.He has been away for a week.(二)主要用法1、表示过去发生并且已经完成的动作对现在造成的影响或结果。
此时,常和谓语动词一起使用的副词有already、just、never、ever、yet 等。
如:They have already come back from the museum.She has already finished her homework.2、表示过去发生的动作持续到现在,并且有可能会继续持续下去。
此时,常和谓语动词一起使用的标志性词语主要有for和since,而且此时的谓语动词往往是持续性动词(如stay、keep、wait等)。
如:I have lived here for ten years.He has kept the clavichord since thirty years ago.3、表示从过去某一时间到说话时这段时间中反复发生的动作。
此时,常和谓语动词一起使用的主要是表频度的副词often、always、seldom、never等,以及表次数的单词或短语(如once、twice、three times)。
如:You have never listened to me like this before.She has ever been to France.They have visited the Summer Palace many times.(三)动词的过去分词1、规则变化其变化规则与动词的一般过去时基本相同,主要是在词尾加-ed或-d。
具体的有:1)直接加-ed。
如:worked、played。
2)以不发音的e结尾的动词后加-d。
如:lived、danced。
3)以辅音字母加y结尾的动词后改y为i,再加-ed。
如:studied、cried。
4)以重读闭音节结尾的动词后,双写最后一个辅音字母再加-ed。
如:stopped、patted。
2、不规则变化如果结合动词的过去式,动词的过去分词的不规则变化中,又有一些相对的规则现象。
如:1)AAA型。
如:put put put;read read read。
其中,read的过去式和过去分词虽然拼写时一样的,但其发音与原形不同,ea不再读作[iː],而是[e]。
2)AAB型。
如:beat beat beaten3)ABB型。
如:keep kept kept;sit sat sat4)ABC型。
如:lie lay lain;drink drank drunk5)ABA型。
如:run ran run;come came come(四)标志性词语1、副词already、just、never、ever、yet等。
如:She hasn't arrived in Scotland yet.They have just left for Shanghai.2、for和since。
for+一段时间,since+具体时间。
如:He has learned Italian for five months.He has learned Italian since five months ago.3、so far和up to/till now。
表示“迄今为止”。
如:So far, no one has heard any news about her.She has read fifty books up to now.4、recently、lately等表示“最近;最新”的副词和形容词。
如:I've met her on several occasions recently.He hasn't had enough sleep lately.5、in the past/last+一段时间,表示“在过去的...时间里”。
如:In the past few years, new buildings have sprung up all over Beijing. He had aged rapidly in the last few months.6、次数。
如:I've tried many times, but there's no way.He has been there at least twice.(五)have been to/have gone to/have been in1、have been to表示“去过已回”。
句子主语就在现场。
如:They have been to Rome many times.She has been to Shanghai more than once.2、have gone to表示“去了未回”。
句子主语不在现场。
如:Jerry has gone to Hangzhou.Mary has gone to Finland.3、have been in表示“一直待在某地”。
如:We have been in Beijing for five weeks.They have been in China since 2012.(六)短暂性动词和延续性动词所谓短暂性动词主要是指一旦发生马上就结束的动作,也叫瞬间动词,如die、marry、leave等。
而延续性动词主要是指可以一直持续进行的动作,也叫持续性动词,如learn、live、talk等。
两类动词都可以用于现在完成时,但是短暂性动词不能与表示一段时间的时间状语连用。
此时,需要把短暂性动词改为相应的表状态的动词或短语。
如:错误:He has died for ten years.正确:He has been dead for ten years.错误:She has married him since five years ago.正确:She has been married to him since five years ago.(七)句型转换因为“have/has done”中的have/has是助动词,所以在进行句型转换中要注意不需要再另外借助助动词do/did/does,而是直接借用have/has。
如:肯定句:He has lived here for the last few years.否定句:He hasn't lived here for the last few years.一般疑问句:Has he lived here for the last few years?特殊疑问句:How long has he lived here? (划线部分为for the last few years)现在完成时专项练习一.用所给词的正确形式填空。
