How long have you had
that bike over there

一、现在完成时通常和表示一段时间的时间状语连用，这样的时间状语有“for + 时间段”、“since + 过去的时间点或从句”或“since＋时间段＋ago”。
注意：现在完成时中含有for、since引导的时间状语中，动词要使用延续性动词。
现在完成时用法三
（1）for +“时间段”
e.g. I have been a teacher for 10 years.
我当老师已经10年了。
（2）since+“过去的时间点”
e.g. I have been a teacher since 2012.
他从1999年开始学英语。
（3）since + 一段时间 + ago = for + 一段时间
e.g. He has been here since five weeks ago.
=He has been here for five weeks.
e.g. 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）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.
（6）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.
二、延续性动词 & 非延续性动词
动作开始
动作结束
开始
结束
延续性动词:可持续一段时间的词
短暂性动词:开始之后很快结束，不可持续
have swim sleep read keep
begin open lend leave buy
finish close borrow come sell
非延续性动词转换为延续性动词
将非延续性动词转化为“be+形容词或副词”
begin (start) (开始)
go there (去哪里)
come back (回来)
come here (来这里)
be on
be there
be back
be here
有的非延续性动词可以转化为意思相同的延续性动词：
borrow → keep(借) become → be (成为)
receive → have (收到) go to sleep → sleep (睡觉)
(穿) put on
(认识) get to know
(买) buy
(感冒) catch a cold
wear / be on
know
have (own)
have a cold
V.→V.
buy
borrow
catch
V.→be+adj.
open
close
die
marry
V.→be+adv
leave
come
go
finish
begin
V.→be+名词短语
join
have
keep
have
be open
be closed
be dead
be married
be away (from)
be here
be there
be over
be on
be a member of
be in
非延续性动词转换为延续性动词

1 begin be on 6 return be back
2 leave be away from 7 join be in
