    小升初英语语法时态重点

    摘要:小升初英语语法时态重点
    现在完成时是由助动词 have(has)+动词的过去分词done构成。助动词have说明该谓语是属于现在时范围。它与主语的人称、数要保持一致。过去分词done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与结果。常与just、already、yet 等副词连用。如:
    ---Have you had dinner yet?你(已经)吃晚饭了吗?
    ---Yes,I have. I''ve just had it. 我刚刚吃过。(强调现在我不饿了)
    (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。常与for与since等表示一段时间的状语连用。
    如:He has livedin ShangHai since 2001.
    他自从2001年就住在上海了。(可能还要继续住下去)
    (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ever,never,twice,three times等时间状语。
    如: I have been to Shanghai three times.我去过上海三次。
    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。
    例如:She has already seen the film.
    She hasn’t seen the film yet.
    Has she seen the film yet?
    Yes,she has./ No,she hasn''t.
    4.现在完成时的时间状语
    现在完成时属于现在时范围,故不能与过去的时间状语连用。但是,在强调动作产生的后果与影响时,可以与一些表示不确定的时间状语连用。有  already,yet,since,for,ever,never,just,before,up to now等。
    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。
    I have never been to the Great Wall.我从未去过长城。
    We have studied English for three years. 我们(开始)学英语已三年了。
    5.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.他们去过上海两次。
    He has gone to Beijing . 他去上海了。
    (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,因此可以与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。  练一练:
    一、用since与for填空。
    1. Jill has been in Ireland Monday.
    2. Jill has been in Ireland three days.
    3. Mike has been ill a long time. He has been in hospital October.
    4. Margaret is in her office. She has been there 7 o''clock.
    5. India has been an independent country 1974.
    二、用所给动词的适当形式填空。---词形大“变态”。
    1. He (live) in Beijing since he was born.
    2. My friend, Chang Li, (buy) a new car last week.
    3. We (not hear) from them for a long time.
    4. I (not read) the book before.
    5. Mother  (make) me a new coat yesterday.
    6. I (see) him go into the hotel just now.
