人教新目标初中英语语法-现在完成时讲解以及练习题(含答案)
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。

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。
现在完成时与现在完成进行时态讲解及练习(含答案)

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。

（说明她现在仍是老师）2.“未完成”用法。

用来持续的动作或状态或表过去重复的动作，如live，study，be，wait等，常和since（自从）或for（经历）引导的词语连用。
如：I have lived here for more than thirty years.我已在此住了30多年。
III.现在完成时的标志1.现在完成时的含义之一是过去完成的动作对现在仍有影响, 现在完成时通常和，ever, never, twice（once…）, so far（到目前为止）, since，for，in the past/last few years（在过去几年）, already（肯定句）, yet（否定，疑问句）, just(刚刚), before（以前）, recently （近来）等词连用说明：already与yet都有“已经”的意思，但already常用于肯定句，并用于句中。
yet 常用于否定句和疑问句，并用于句末。
例如：I have already finished my homework.I haven’t finished my homework yet. Have you finished your homework yet?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)I can’t find my watch now. I think I have already lost it.2.过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手。

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。
