关于在英语写作中可加分的现在完成时句型使用方法分享
关于现在完成时我相信应该有很多孩子都是弄不清楚的,小编也是,在写作文的时候总是用不对这个语法,今天就让小编为大家整理一份超级详细的现在完成时使用方法吧,一起来学习一下吧。
现在完成时的基本结构一
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)
现在完成时的用法二
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 cold
现在完成时常见考法三
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。
【典型例题】
His father_____the party since 1978
A.joind
B.has joined
C.was in
D.has been in
答案:D
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,A、B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。
比较一般过去时和现在完成时的异同四
1. 共同点:动作都是在过去完成。
I saw the film yesterday evening.
I have seen the film before.
(看电影这件事都是在过去完成的。)
2. 区别:
①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。
②一般过去时通常与具体明确的过去时间状语连用。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 等模糊的过去时间状语和 these days ,this week ,since..., for... 等表示一段时间的状语连用。
【典型例题】
—______ you your homework yet ?
—Yes . I _____ it a moment ago .
A.Did ; do ; finished
B.Have ; done ; finished
C.Have ; done ; have finished
答案:B
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 是一个明确的过去时间状语,应该用一般过去时。

动词过去分词的规则变化与动词过去式的规则变化相同。
① 一般情况下,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
