Grammar Focus
含义: 表示动作从过去某一时间开始一直延续到现在。这一动作可能刚刚开始, 也可能在继续, 其动作是否继续下去, 由上下文而定。这个时态多用于延续性动词。
时间状语:
1. for +一段时间 e.g. for 8 years
2. since +过去的时间点 e.g. since 1999
3. since + 一段时间+ ago e.g. since 23 years ago
现在完成时
for 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”
e.g. He has studied English for five years.
(2) since后须接“时间点”
e.g. He has studied English since 1999.
(3) 二者可以转换
for +一段时间 = since + 一段时间 + ago
e.g. He has been here for five weeks.
= He has been here since five weeks ago.
(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。
e.g. He has taught here since he came to China.
We have been friends since we met in school.
(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
e.g. It is four days since last Friday.
It has been two years since Jim came to Beijing.
② This is the first (second…) time that + 从句（句型中的that从句通常使用现在完成时）
e.g. This is the first time that Jenny and Danny have been to China.
This is the third time that I have seen 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。
e.g. I have bought this computer since four years ago. (×)
I have had this computer since four years ago. (√)
I haven’t bought anything for two months.(√ )
I haven't heard from him for 3 weeks. (√)
