八年级英语语法现在完成时练习题及答案
一、时态讲解：现在完成时（1）构成：现在完成时由助动词have + 过去分词构成，助动词have 有人称和数的变化。
第三人称单数用has，其余用have.现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。
以study 为例，其否定式、疑问式和简单回答形式如下：（2）用法：1）现在完成时通常表示在说话之前已经完成的动作或存在的状态。
说话人强调的是该动作或状态对现在的结果或影响。
My daughter has just gone out.我女儿刚出去。
I’m sure we’ve met before. 我肯定我们以前见过面。
She has arrived. 她到了。
2）表示持续到现在的动作或状态，往往和包括现在在内的表示一段时间的状语连用，如recently, already, just, lately, for…, since…,yet等。
如：I haven’t heard from her these days. 这些日子我没有收到她的信。
We haven’t seen you recently. 最近我们没有见到你。
They have been away for two years. 他们离开已经两年了。
She has been with us since Monday.★注意：a)since和for的区别since后接时间点，如1993，last term, yesterday, the time I got therefor后接一段时间，表示“长达多久”，如ten years, a while, two days等。
Exercise: 用since和for填空1. Jim has been in Ireland ______ Monday.2. Jill has been in Ireland ______ three days.3. His aunt has lived in Australia ______15 days.4. Mary is in her office. She has been there ______ 7 o'clock.5. India has been an independent country ______1974.6. The bus is late. They've been waiting ______ 20 minutes.7. Nobody lives in those houses. They have been empty ______ many years.8. Mike has been ill ______a long time. He has been in hospital ______ October.2）表示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等，在完成时当中不能和表示一段时间的状语连用，因为它们表示的动作不可能持续。
人教版英语八年级下册Unit8语法全解：现在完成时
语法全解：现在完成时一、现在完成时的构成〔一〕肯定式主语＋助动词have/has＋过去分词＋其它.说明：这里的have/has是助动词，没有什么具体意义。
当主语是第三人称单数时助动词用has，其余人称一律用have。
has, have的缩略式分别为’s或’ve。
规那么动词过去分词的构成与过去式的构成方式一样，不规那么动词可参看不规那么动词表。
实例：1) I’ve just copied all the new words.我刚抄写了所有的生词。
(表示不要再抄了)2) She has lost her books.她丧失了她的书。
〔表示到目前为止还没有找到〕(如果用过去时：She lost her books.那么强调书是过去丢的这一动作，而不知现在有没有找到。
)3) We’ve just cleaned the classroom. 我们刚好清扫了教室。
〔说明现在教室是干净的〕〔二〕否认式主语＋助动词have/has＋not＋过去分词＋其它.说明：现在完成时构成否认句时，只需在助动词have/has后面加not就行。
have not, has not的缩略式分别为haven’t, hasn’t。
另外，肯定句中有some, already时，改为否认时要分别改成any, yet。
例：1)I haven’t finished my homework yet.我还没有完成我的作业。
2)She hasn’t travelled on a train. 她没有坐火车旅行过。
3)We have never spoken to a foreigner．我们从来没有和外国人说过话。
注：有时not可以用never代替，表示“从来没有〞的意思。
又如：4) I have never seen him before.以前我从来没有见过他。
〔三〕一般疑问式助动词Have/Has ＋主语＋过去分词＋其它？说明：把陈述句中的have或has放到句首，句末打问号，同时把句中的some, already改为any, yet就构成了一般疑问句。

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。
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 ondie →be dead come back→be backleave →be away fall ill(sick,asleep)→be ill(sick,asleep)get up→be up go out →be outfinish →be over put on →wear 或be onopen →be open join →be in或be a member of…close →be closed go to school→be a studentborrow →keep buy →havecatch(a cold)→have(a cold) get to know →knowbegin 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。
4.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）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。
