其结构也是：
have / has +动词的过去分词.
常用的时间状语有:
already, just, 一般置于have/has 之后，用于肯定句中；在否定句中则要用yet 表示“还，未”。Grammarfor 和 since 在现在完成时中的应用for与since都能与现在完成时连用，但区别较大：
（1）for后须接“时间段”
He has studied English for five years.
他学英语5年了。
（2）since后须接“时间点”
He has studied English since 1999.
他从1999年开始学英语。（3）二者可以转换
for + 一段时间 = since + 一段时间 + ago
He has been here for five weeks.
= He has been here since five weeks ago.
他到这儿已经有五个星期了。如：
He has taught here since he came to China.
自从他来到中国就在这儿教书。
We have been friends since we met in school.
我们从在学校见面起就成为了好朋友。(4) since能引导时间状语从句(主句用现在完成时，从句用一般过去时)，而for则不能。（5）现在完成时常用句型：
①It is (has been) +时间段+ since +时间状语或从句
It is four days since last Friday.
从上周五到现在已经四天了。
It has been two years since Jim came to Beijing.
吉姆来北京已经两年了。②This is the first (second…) time that + 从句
句型中的that从句通常使用现在完成时。
如：
This is the first time that Jenny and Danny have been to China.
这是珍妮和丹妮第一次来屮国。
This is the third time that I have seen Karen.
这是我第三次见到Karen。（6）均须与延续性动词连用，也可以与非延
续性动词的否定式连用。
