【点睛】1.Since自从---以来(可做介词和连词),和现在完成时态连用。

It is three years since he joined (终止性动词)the army.他参军有三年了;It is five years since he lived(持续性动词)here.他离开这有五年了。

现在完成时与现在完成进行时态讲解及练习(含答案)

时态现在完成时一.基本结构:助动词have/has+过去分词(done) 。
表示过去发生的动作对现在造成的影响,或过去发生的动作还未结束,一直持续到现在或将来,重点在于对现在的影响。
二.句型:否定句:主语+have/has+not+过去分词+其他.一般疑问句:Have/Has+主语+过去分词+其他.简略答语: Yes, 主语+ have/has.(肯定)No, 主语+ haven't/hasn't.(否定)三.用法1.“已完成”用法 :表示一个过去发生并结束的动作对现在造成的影响或结果。
这一类情况可以细致分为下述两种情况。
1)表示开始于过去的动作刚刚结束。
常和just,now,already,yet,not…yet等不确定的时间状语连用。
Li Ming has just turned off the light. 李明刚刚把灯关上。
(说明现在灯关上了)I've finished my homework now. 现在我已经做完作业了。
(说明可以交作业或做别的了)2)表示过去动作的结果,现在仍残留着。
一般不用时间状语。
I have lost my pen. 我把笔丢了。
(说明过去某时丢的,现在我还没找到这支笔)She has become a teacher. 她已经当了老师。
(说明她现在仍是老师)2.“未完成”用法。
表示动作或状态从过去某时开始,持续到现在的动作(用行为动词表示)或状态(be动词表示),常与for(+段时间)、since(+时间点或过去时的句子)连用。
①for+时段(for a long time,for a month)②since+过去一个时间点(译为:自从……以来,如since 1991 、since yesterday)③since+时段+ago (since 2 days ago)④since+从句(过去时)●⑤It is+时段+since+从句(过去时)⑥其它常见:today,this week(month),lately,recently,these days,in the past few days,during the last two weeks,,so far,up to now,till(until)now等。
现在完成时讲解与练习题(含答案)

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:1)since和for的区别since后接时间点,如1993,last term, yesterday, the time I got there。
for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。
现在完成时讲解和练习(有答案)

现在完成时讲解和练习1. 现在完成时的构成: have\has+过去分词(过去分词的构成有规则变化和不规则变化)2. 现在完成时的四个基本句型肯定句He has finished the work.一般疑问句Has he finished the work 回答Yes ,he has. No, he hasn’t.否定句He has not finished the work.特殊疑问句What has he done3.现在完成时的用法:A.表示过去发生或已经完成的动作对现在造成的影响或结果,强调对现在造成的影想或结果)。
例如:Thecarhasarrived.车子来了。
(结果:车子已在门口)Someonehasbrokenthewindow.有人把窗户打破了。
(结果:窗户仍破着)B.表示过去已经开始,持续到现在的动作或状态,可以和表示从过去某一时刻延续到现在(包括“现在”在内)的一段时间的状语连用,如for+时间段、since+过去的时间点、疑问词howlong等。
例如:Myunclehasworkedatthisfactoryforfiveyears.我叔叔在这个工厂工作已经五年了。
Mr.BlackhaslivedinChinasince2002.自从2002年Mr.Black一直住在中国。
Howlonghaveyoubeenhere你来这里多久了4. 在下列情形下用现在完成时(1)九词语①already已经肯定句中或句尾.: I have already found my pen.= I have found my pen already.②yet已经否定句和疑问句句尾.:I have not finished the work yet.Have you bought a computer yet ③ever曾经句中.:Have you ever seen pandas④never从不句中.:I have never been to Beijing.⑤just刚刚句中.:I have just done my work.⑥before以前句尾.:I have never been there before.⑦so far到目前为止.:So far he has learnt 200 words.⑧how long多久.:How long have you lived here⑨how many times多少次.:How many times has he been to Beijing(3)三词组<has>gone to去了某地表示“已经去了某地,在去那里的途中或到达那里还没有回来”.:He has gone to Beijing (去了北京)<has>been to去过某地表示“曾去过某地,已经从那里回来了”.:He has been to Beijing. (去过北京)<has>beenin表示“在某地呆多长时间”,常与表示一段时间的状语连用,如:since,for,howlong .: Mr.BrownhasbeeninBeijingforthreedays.布朗先生来北京已经有三天了4.如果句子里面没有时间状语,汉语意思能够加“已经”,往往用现在完成时态。

现在完成时讲解及练习(答案)

初中英语主要时态系列(六)——现在完成时讲解及练习1现在完成时的基本结构肯定句:主语+have/has+动词的过去分词+其他否定句:主语+have/has+not+动词的过去分词+其他一般疑问句:Have/Has+主语+动词的过去分词+其他特殊疑问句:特殊疑问词+一般疑问句(have/has+主语+过去分词+其他)2现在完成时的用法1. 现在完成时用来表示过去已经完成的动作对现在造成影响或后果。
也就是说,动作或状态发生在过去但它的影响现在还存在,强调的是现在。
I have already posted the photo.我已经邮寄出了照片。
与此种用法连用的时间状语时一些模糊的过去时间状语,如already(肯定句句中), yet(否定句/疑问句句尾), just, before, recently,still, lately,never 等。
2. 现在完成时也可用来表示动作或状态发生在过去某一时刻,持续到现在并且有可能会继续持续下去。
He has lived here since 1978.自从1978年以来,他一直住在这儿。
(动作起始于1978年,一直住到现在,可能还要继续住下去。
)此种用法常与for(+时间段),since(+时间点或过去时的句子)连用。
谓语动词必须是延续性动词。
有些瞬间动词可变为延续动词:go out----be out finish----be over open----be open die----be dead buy---have fall ill---be ill come back----be back catch a cold----have a cold3现在完成时常见考法对于现在完成时的考查,多以单选、句型转换或词语运用的形式考查学生在具体语境中灵活运用时态的能力。
在考试中,会让大家判断是否该用现在完成时,或者是考查“瞬间动词”不能与表示一段时间的状语连用”这一知识点。

【答案】C
【解析】
