英语语法教学 现在完成时复习
简析:现在完成时的时间状语常有如下 四类:
⑴ 现在完成时常与already(已经),just (刚 刚,正好),ever(曾经),never (从来,也不;从不),before(以前), yet(仍然)等连用。
⑵现在完成时常与recently(近来), so far(到目前为止),in the past/“last + 一段时间”等时间状语连 用。因为上述短语表示的是从现在起往 前推算的一段时间,句中的动作是从过 去某一时间或时刻开始持续到现在的。
1. have/has been to表示“过去曾去过 某地”,但现在已经回来了。
2. have/has gone to表示“已去了某 地”,现在还没有回来。
3. have/has been in 表示“已在某地 (呆了多久)”,如果是小地方用at代替in。

现在完成时的用法讲解
现在完成时的用法复习整理一、谓语部分结构:助动词have (has) +过去分词过去分词的构成分规则的和不规则的,规则的与过去式的构成方法一样,不规则的只有单独记了,无人能帮你。
1.肯定句:主语+have( has) +过去分词+其它。
2. 否定句:主语+have( has)+ not+过去分词+其它。
have not=haven’t has not=hasn’t.3.一般疑问句结构:Have( Has )+主语+过去分词+其它?4.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.二、常搭配的时间状语:already, yet, just, ever, never,in thepast +时间段,so far这几个词的位置除了yet常在句尾外,其余的通常都在句中,即have/has的后面,行为动词的前面。
但already也可在肯定句尾,表示强调,在疑问句末尾表示惊讶等。
eg. Has he finished his homework already? 对他完成了作业感到惊讶。
另,before 也可以与现在完成时连用。
eg. I’ve ever been there before. It was ten years ago.三、常用用法1、表示过去发生或者已经完成的动作对现在造成的影响或者结果。
Eg.The doctor has left .(他现在不在这儿,找不到他了。
)The students have cleaned the classroom.(现在教室是干净的)I have just read the book.( 现在我知道这本书的内容了)比较:I read the book last month.(只是说明read这个动作是在上个月发生的而已,没有谈及对现在有什么影响)总结:现在完成时与一般过去时的区别:现在完成时强调的是过去发生的动作对现在造成的影响或者结果,强调的是现在的情况或者状态,与过去没有关系,不能和表示过去的时间状语连用。
现在完成时专项复习和训练
现在完成时时态讲解一、注意弄清时态的实际意义现在完成时表示的是在过去某个时间开始并持续到现在的动作/状态,或者过去的动作或状态对现在造成的影响或结果。
They have left. --他们已经离开了,也就是说现在他们人不在这里I have had my lunch. --我已经吃过午饭了,也就是说我现在不饿也可表示持续到现在的动作或状态,或有可能有可能停止,或有可能继续延续下去。
He has learned English since 2001. -从2001年开始学的,现在还在继续学着呢二、基本句型结构现在完成时的构成形式:have /has (助动词)+done(过去分词)I/You/They/We have talked . He/She has talked.现在完成时的否定结构就是在助动词have或has后加上否定词not;I/You/They/We haven’t(have not) talked . He/She hasn’t(has not) talked.其一般疑问句就是将助动词have或has提到句首,Have I/You/They/We talked . Has he/she talked.肯定的简略回答是:Yes,主语+have/has.,否定的简略回答是:No,主语+have/has not.。
如:I have seen the film. →Have you seen the film?Yes,I have./No,I haven’t.三、注意掌握两种基本用法1.“过去的经历”:动作发生在过去的某一时刻且已经结束,但未说明动作发生的具体时间或情景,强调该经历(即动作发生后)对现在所造成的影响或产生的结果。
如:I have heard of the man. 我听说过这个人。
2. “完成情况”:表示过去已经开始并持续到现在的动作或状态,或有可能继续延续下去。
句子中一般有说明其完成情况的短语或从句。

区分短暂性动词与持续性动词.
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,或点动词),如begin,start,die,buy,leave, come等,表示动作的发生与结束于一瞬间完成,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+时间段, since+时间点/从句连用,也不能用在how long引导的 特殊疑问句
现在完成时(复习专用)
现在完成时现在完成时的用法: 现在完成时表示过去某时发生的行为对主语目前产生的影响。
现在完成时常被称为“与现在有联系的过去”,因此它不能与明确的过去时间状语连用。
现在完成时和一般过去时的比较①两者都可表示过去发生过的动作:但前者表示的是过去的动作对现在的影响,而后者则只是表示过去有这一动作的事实。

)He has locked the door. 他把门锁上了。
(现在门是锁着的。
)Who turned on the light? 谁开的灯?(着眼开灯的动作,不管现在灯是开是关。
)Who has turned on the light? 谁把灯打开了?(着眼开灯的结果,即现在灯还亮着。
)②两者都可表示过去开始并延续了一段时间的动作:现在完成时表示该动作仍在继续,而一般过去时则说明该动作现已终止。
