因此，我们可以根据这些时间状语来判断是否使用现在完成时态
“for+时间段”
“since+过去的时间点”
“since+从句(一般过去时态)”
“since+时间段+ago”。
=“since+同一时间段+ago”
且for与since引导的时间状语可以相互转换。
提问需用疑问词____________
How long
Use for or since to form adverbials of time:
________ 5 years ________ last Monday
________ you came here ________ a long time
________ 2018 ________ his 7th birthday
________ 2 days ________ 2 days ago
for

since
for

3.The film has been on ______ 20 minutes.
2.His father has been in the factory ______ 10 years ago.
5.His grandparents have been dead ______ 2004

观察以下几个句子，现在完成时中的动词有什么
共同特点？
1. How long has he borrowed the book ×
How long has he kept the book ∨
2. Tony has bought the computer for one year. ×
Tony has had the computer for one year. ∨
3. How long has Mary left ×

在现在完成时中，与“for + 时间段”
“since + 过去的时间点或从句”或
“since ＋时间段＋ago”连用的动词
必须为延续性动词。
在现在完成时中，与“for + 时间段”
“since + 过去的时间点或从句”或
“since ＋时间段＋ago”连用的动词
必须为延续性动词。
动词按其动作发生的方式，发生过程的长短可分为延续性动词与非延续性动词。
延续性动词与非延续性动词
1)延续性动词:表示能够延续的动作,也可以表示经验与经历。
Eg: learn, work, stand, lie, walk, sleep, keep, wait, watch, sing, read, stay, live …
延续性动可以与for和 since引导的时间状语连用:
(他在这儿住了六年了,一直住在这儿,live是延续性动词，并且很有可能继续居住)
I have known her since then.
(自从那时起我就认识她了,一直都
认识,know是延续性动词)
Eg: He has lived here for 6 years
非延线性动词不能与for和since引导的时间状语连用。
He has died for two years. (X)
He has been dead for two years. (√)
I have bought the bike for 2 months. (X)
I have had/owned the bike for 2 months. (√)
2)非延续性动词:动作发生后立即结束。
Eg: open, close, begin, finish, come, go, move, borrow, lend, buy, die …
