现在完成时语法解释大全
现在完成时语法解释大全一、现在完成时的定义现在完成时是表示动作或状态发生在过去，但与现在有关联的一种时态。
这个时态强调对现在产生的影响或结果，常用于描述已经发生的事情，特别是与现在情况有关联的事情。
二、现在完成时的基本结构现在完成时的基本结构是“have/has + 过去分词”，其中“have/has”是助动词，表示现在完成时的时态。
“过去分词”是动词的过去形式。
三、现在完成时的常用时间状语现在完成时常用的时间状语包括：already（已经）、yet（尚未）、before（以前）、recently （最近）、lately（近来）、since（自从）、in the past few years（在过去的几年里）等。
四、现在完成时的否定形式现在完成时的否定形式是在助动词“have/has”前面加上“not”，即“have/has not + 过去分词”。

）五、现在完成时的疑问形式现在完成时的疑问形式是在助动词“ha ve/has”前面加上疑问词“have/has”，后面跟动词的过去分词，即“Have/Has + 主语+ 过去分词?”。

例如：“I finished my homework an hour ago.”（我一小时前完成了作业。
）（用一般过去时）和“I have finished my homework now.”（我已经完成了作业。
）用现在完成时则强调现在不需要做作业了，对现在的情况产生了影响。

如：1）I have finished my homework. 我做完家庭作业了。
（过去某时开始做，到现在已完成）2）He has already come 他已经来了。
（过去某时开始离开某地到这来，现在已在这。
）2. 表示动作发生在过去并延续到现在,有可能继续延续下去。
如：1）I have studied English for six years. 我已经学了六年英语了。
（六年前开始学英语，一直学到现在, 也可能继续学也可能就此不学了。
）2）I have lived in Shenyang since 1990. 我从1990年就在沈阳住。
（从1990年开始住在沈阳一直住到现在，也可能继续住也可能就此为止。
）二、现在完成时的结构1）肯定式：主语 + have / has + 过去分词2）否定式: 主语 + have / has + not + 过去分词3）一般疑问式 Have / Has + 主语 + 过去分词4）特殊疑问式特殊疑问词+have/has+主语+过去分词三、现在完成时的时间状语现在完成时常用的时间状语包括“already, yet,ever, etc”。
例如：We have learned about 3000 English words by the end of this term.到上学期末我们已经学了3000个英语单词。
注意：1) 当表示一段时间，现在完成时可以用for 或since引导的状语。
例如：I’ve known Li Li for 4 years. 我认识丽丽已经4年了。
I have worked here since 8 years ago. 自从8年前我就在这工作。
2) 当在肯定陈述句中含有already或just 时，在转换成否定句时，要把句中的already 或just 去掉，在句末加上yet.。
例如：I have already seen the film. ------ I haven’t seen the film yet.He has just come. ------He hasn’t come yet.注意：for和since的用法。
①for+时段为…时间②since+过去一个时间点（译为：自从……以来）③since+时段+ago④since+从句（过去时）⑤It is+时段+since+从句（过去时）四、过去分词变化规则如下：1 、规则动词：规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。
四点变化规则：（1)一般动词，在词尾直接加“ ed ”。
work---worked---worked ,visit---visited---visited(2)以“ e ”结尾的动词，只在词尾加“ d ”。
live---lived---lived ,(3)以“辅音字母+ y ”结尾的动词，将 "y" 变为 "i" ，再加“ ed ”。
study---studied---studied ,cry---cried---cried(4)重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“ ed ”。
stop---stopped---stopped , drop---dropped--dropped2 、不规则动词变化需参看不规则动词表逐一熟记。
例如; cut- cut- cut,hit-- hit-- hit.五、使用时注意事项1.“have/ has got ” 形式上是一种完成时，但和have/ has 为同一意思“有”。
例如：Have you got pen-friends? Yes, I have.你有笔友吗？是的，我有。
Has he got a lot of work to do? No, he hasn’t.他有许多工作要做吗？不，他没有。
2. have/has gone to 、have/has been to 和have/has been in的区别。
have/ has gone to 去了，在去某地的路上或在某地，人还未回来have/ has been to 曾经去过，人已经回来了have/ has been in 已经在，常与一段时间连用He has been to Shenyang before. 他以前曾去过沈阳。
He has been in Shenyang for ten years. 他在沈阳10年了。
Has he gone to Shenyang? 他去沈阳了吗？3. have/ has been to常和once, twice, never, ever连用；have/ has gone to则不可。
例如:─ Has Tom ever been to Paris? 汤姆去过巴黎吗？─Yes, he’s been there many times. 是的，他去过好几次了。
─ Where have they gone? 他们去哪里了？─They’ve gone to Shenyang. 他们去沈阳了。
4．非延续性动词(或称作终止性动词)不能用“现在完成时 + 表示一段时间的状语”的句型中。
这类动词有：come, go, start, leave, die, buy, finish, join, borrow, stop等。
但它们能够用表示持续状态的相应的延续性动词替换句中的终止性动词。
arrive, come → be here, be in buy → havebegin, start → be on die → be deadget up → be up leave, move → be away；go out → be out borrow→keepfinish/end →be over open →be openclose →be closed join— be a member of六、现在完成时往往同表示不确定的过去时间状语连用，如already（肯定）, yet（否定，疑问）,just, before, recently,still, lately,never等.例如: He has already finished the work..典型例题1：His father_____the party since 1978A.joindB.has joinedC.was inD.has been in解析：本题考查学生对现在完成时的熟练掌握。
since 1978表达“自从1978年一直到现在”，表示这件事情从过去一直持续到现在，应该用现在完成时，而且动词必须是延续性动词，AB均为瞬间动词，不能与时间段连用，故排除；C为一般过去时，也不行。
答案；D.要牢记：一般过去时通常与表示过去的时间状语连用。
如：yesterday, last week , two years ago ,just now ,in 2002 等；而现在完成时则常与just ,already ,ever ,never 等副词和these days ,this week ,since ......, for ...... 等表示一段时间的状语连用。
现在完成时强调过去发生的动作对现在的影响和结果，而一般过去时与现在没有联系，只是说明某个动作发生的时间是在过去。
典型例题2：—______ you ___ your homework yet ?—Yes . I _____ it a moment ago .A.Did ; do ; finishedB.Have ; done ; finishedC.Have ; done ; have finished解析：本题考查一般过去时和现在完成时的用法区别。
问句中的yet表明应该用现在完成时，而回答中的a moment ago 是一个表示过去的时间状语，应该用一般过去时。
