Present Perfect Tense
现在完成时
表示从过去已经开始持续到现在的动作或状态,可以和表示“从过去某一时刻延续到现在的一段时间状语”连用,如“for+时间段”、“since+过去时间点”、“since+过去时的从句”、“since+一段时间+ago”。且for与since引导的时间状语可以相互转换。
e.g. My uncle has worked at this factory for
ten years.
= My uncle has worked at this factory
since ten year ago.
I’ve lived here since 1990.
自从1990年以来我就住在这里。
I haven’t seen him for three years.
我三年没有看见他了。
She’s been at this school since five
years ago.
自从五年前她就在这个学校。
含有for,since的现在完成时的用法歌诀: 过去的动作或状态,
一直持续到现在,
for、since 把时间带。
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.
他学英语5年了。
(2)since后须接“时间点”
e.g. He has studied English since 1999.
他从1999年开始学英语。
for 和 since 在现在完成时中的应用
(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.
他到这儿已经有五个星期了。
(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.
自从他来到中国就在这儿教书。
(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.
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。
e.g. This is the first time that Jenny and
Danny have been to China.
这是珍妮和丹妮第一次来中国。
This is the third time that I have seen
Karen.
这是我第三次见到凯伦。
(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 had this computer since four years ago.
I haven’t bought anything for two months.
I haven’t heard from him for 3 weeks.
(7)二者引出的时间状语往往用 how
long提问。
e.g.
— How long have you had this book
— For a week./Since a week ago.
— 这本书你买多久了
— 买一周了。
1.转换为相应的延续性动词,用于现在完成时。
borrow — keep buy — have
put on — wear
catch a cold — have a cold
get to know — know
get to sleep — sleep
非延续性动词和延续性动词之间的转换
2. 转化为“be + 形容词/副词/介词/名词”
begin / start — be on
go out — be out
close — be closed
open — be open
get to/arrive/reach — be (in)
die — be dead
leave — be away
finish — be over
fall asleep — be asleep
join — be in/be a member of
become — be
make friends — be friends
come/go/ — be + 相应的介词短语
