现在完成时练习
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=haven’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 days. 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。 His father has been dead for two years.他父亲去世二年了。 The film has been on for ten minutes.电影已开始十分钟了。 We have studied English for three years. 我们（开始）学英语已三年了。 5.现在完成时和一般过去时的区别 现在完成时和一般过去时都表示在过去完成的动作。但现在完成时强调的是这一动作与现在的关系。如对现在产生的结果或影响等，而一般过去时只表示动作在过去某一时刻发生，不表示和现在的关系。试比较： I have lost my new book. 我把新书丢了。（现在还未找到） I lost my new book yesterday. 我昨天把新书丢了。（昨天丢的，现在找到与否没说明） 6.几点注意事项 （1）have been(to)与have gone( to)的区别：have been(to)表示“去过某地（现在已经回来了）”，可用于各人称；have gone(to)表示“去某地了（说话时某人不在当地）”，常用于第三人称，前者可与once ,never,several times等连用，后者则不能。如：They have been to Beijing twice.他们去过北京两次。 He has gone to Beijing . 他去北京了。 （2）如单纯表示一段时间，或强调一段时间，虽有since一词，也不必用完成时。如：It is two years since his father died. =His father has been dead for two years.他父亲去世已有三年了。 （3）终止性动词现在完成时的否定式，已变成一种可以延续的状态，因此可以和表示一段时间的状语连用。 如：I haven't left here since 1997.自从1997年以来，我一直没有离开过这儿。
