Look at these sentences.
The Greeks have tried to capture our city for ten years.
I have not laughed like this since my childhood.
since+点时间
for+段时间
如何区分段时间和点时间呢？
区别点时间和段时间：
5:30
five years

2015

since和for的用法：
since:自……以来
since+过去的点时间
He has stayed here since 5 o’clock yesterday.
since+段时间+ago
He has stayed here since 5 hours ago.
since+从句(动词用过去时)
She has taught English since he came here.
for:长达
for+段时间
He has kept the book for 2 weeks.
用for或since填空。
1.We haven’t seen each other _____ a
long time.
2.His father has been in the Party _____
ten years ago.
3.Mr Green has worked here _____ he
came to China.
4.The film has been on _____ 20 minutes.

Look at these two sentences. Do you think they are right or wrong
I have bought this book for 3 years.
I have bought this book since 3 years ago.
瞬间动词不能与段时间连用表示动作的连续性，应改用持续性动词。
I have had this book for 3 years.
I have had this book since 3 years ago.
持续性动词表示能持续一段时间的动作或表示状态的词，如work，stay，live，learn等。
●
瞬间动词表示短暂的动作，从开始到结束，几乎同时或在极短的时间里就完成，如come，go，leave，start，begin，become，receive，die等。
●
He has come back for three weeks.
He has come back since three weeks ago.
He has been back for three weeks.
He has been back since three weeks ago.
他已经回来三周了。
1. 少数瞬间动词可以转换为其相应的持续性动词，如：
borrow → have/has kept，
buy → have/has had
瞬间动词转换为表持续的动词或者表状态的短语后即可在现在完成时中与表示一段时间的状语连用。
arrive in/at → have/has been in/at,
join → have/has been in或
have/has been a member of,
die → have/has been dead,
leave → have/has been away,
begin/start → have/has been on,
end/finish → have /has been over
2. 有些瞬间动词可以用相应的介词短语、 形容词、副词或名词与be的现在完成时连用，表示状态的延续，如：
Look at these two sentences. Do you think they are right or wrong
I haven’t heard from him for a year.
I haven’t heard from him since March.
在否定句中，瞬间动词可以与for 或since+时间状语连用，说明某个动作不发生的状态已持续了一段时间。
现在完成时 相同点 不同点
for 1. 肯定句中与延续性动词连用
2.否定句中动词既可以用延续性动词，也可以用瞬间性动词 for + 段时间
since
点时间
since + 段时间+ago
从句(过去时)
1. How long have you played football
你踢足球踢了多长时间了？
2. How long have you been like this
