八年级英语下册-现在完成时态的讲解与练习-人教新目标版

现在完成时讲解与练习 1.构成现在完成时是由助动词 have(has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和 主语的人称、数要保持一致。过去分词是主要的谓语动词,说明句子的意义。 2.用法 (1)表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。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.结构 1).陈述句结构:主语+have( has)(not)+过去分词+其它。have not=h aven’t has not=hasn’t. 2).一般疑问句结构:Have( Has )+主语+过去分词+其它 3).特殊疑问句:特殊疑问词+have(has) +主语+ 过去分词+其它 eg. He has already finished his homework. He hasn’t finished his homework yet. Has he finished his homework yet --Yes, he has./ No, he hasn’t./ No, not yet. (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。 4.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。多用于否定或疑问句中,表示“曾经”或“从未“等。如 -Have you ever been to the Great Wall你曾经去过长城吗 -I have never been to the Great Wall.我从未去过长城。 c.用表示到说话为止的过去时间状语,如just, before, up to now, the past few years等。例如: I have seen her before, but I can not remember where.我以前见过她,但记不起在哪里见过。 He has been there three times the last few years.近几年他去过那里三次了。 d.用包括“现在”在内的时间状语,如:now, today, this morning (month ,year, term)等。例如 -Have you met him today-No,I haven't.今天你见过他吗我没有。 How many times have you been there this year 今年你去过那里多少次 (2)现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始, 一直持续到现在。如:I haven't seen him for two years. 但是,像come, arrive, buy等终止性动词不能与 表示“一段时间”的状语连用。要用,必须改为“be(在)”等延续性动词来表述。现归纳总结一下由非延续性动 词到延续性动词的转换: arrive→be here begin(start)→be on die →be dead come back→be back leave →be away fall ill(sick,asleep)→be ill(sick,asleep) get up→be up go out → be out finish →be over put on →wear 或be on open →be open join →be in或 be a member of… close →be closed go to school→be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study→study come to work →work等 如:He has been a soldier for three years.他参军三年了。

现在完成时态讲解

语法探知:现在完成时态 一、掌握结构:助动词have/has + 动词的过去分词 二、掌握用法: 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 (次数)等连用,也可以和包括现在在内的时间状语,如these days, today, recently, this year, so far(=by now)等连用. e.g. I have already posted the letter. (信已经不在我这儿了) 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(during) the last(past) ten years等,谓语只可用延续性动词。 我们知道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,或短暂性动词),如begin, start, die, buy, leave, come等,表示动作在一瞬间之内就能完成,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+段时间,since+点时间/从句连用,也不能用在how long引导的特殊疑问句中。(但在否定句中短暂性动词可以与for和since短语连用。) 如:They’ve left London for five days. (×) They’ve been away from London for five days. (√) 三、掌握短暂性动词如何转换成延续性动词 常见短暂性动词与延续性动词的对应关系如下: come/go/arrive/get/reach/move—be in/at open—be open die—be dead close—be closed become—be borrow—keep begin/start—be on put on—wear leave—-be away (from) buy—have fall asleep(ill)—be asleep(ill) end/finish—-be over catch a cold—have a cold join the army—be in the army/ be a soldier join the Party—be in the Party/ be a Party member get to do —do (get to know—know) get married —be married get up —be up begin to do —do (begin to study—study)
