【重点语法】现在完成时态

（一）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）

（二）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 cold

（三）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。

【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。

过去分词的规则变化

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 &34;y&34; 变为 &34;i&34; ，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--dropped

6

过去分词的不规则变化

【典型考例1】

----Is everyone here, Jonathan?

----No. Sir. Millie is absent. She for two days.

A.has fallen ill B. has been ill C. fell ill D. was ill

【析】正确答案B。句意是：乔纳森，人到齐了吗？老师，没有。米莉缺席了。她生病已经两天了。Fall ill与be ill都表示“生病”，但fall ill为非延续性动词，在现在完成时中不可与段时间连用，须转换为be ill才可以，所以，正确答案为B。

【典型考例2】

---Jenny, your new tape player looks great.

----Oh, it’s not new. I _____ it for three years.

A.buy B.have had C.bought D.have bought

【析】正确答案：B。句意是：詹妮，你的新随身听看上很不错啊！哦，它不是新的。我已经买了3年了。非延续性动词buy在现在完成时中，不可与段时间状语连用，因此，须转换为延续性同义动词have或own。所以，正确答案为B 。
