2) I learned how ___________(ride) a bike on it.
3) I ______________(买) it since I ______ (be)a child.
二、合作探究，质疑解惑
1.【语法详解】表示过去发生的动作或状态持续到现在，还可能继续下去。谓语动词为，句中常带有表示一段时间的时间状语，如：since结构，for+一段时间，recently, lately, these days; in the last / past three years by the end of …,（到……为止）so far (到目前为止)， by now=up to now, today等。
She’s been there for over two years 她在那两年多了。
They’ve lived here since 1989/ since they came to this city.
I have learned about 2000 English words so far.
注意：常用How long …..? 提问现在完成时的时间。
1）延续性动词：动作可持续一段时间，可和for, since等表示一段时间的时间状语连用。
2）非延续性动词：动作不能持久，一瞬间就结束，不能延续，或表示一次性动作，也叫短暂性动词、瞬间动词、终止性动词。不能和表示一段时间的时间状语连用。常见这类动词有 come, go, leave, begin, start, arrive, reach, see, die, join, get up, borrow, lend, buy, finish, end, become, hear from等。
*判断正误如有错误并改正:
- He has come back. ( )___________________________________
- He has come back for 3 days. ( )___________________________________
- I have borrowed the book. ( )___________________________________
- I have borrowed the book since last week. ( )____________________________
- I have got up for an hour. ( )____________________________
- He has died for 10 years. ( )____________________________
3)非延续性动词的否定式已成为一种可延续性状态，可以和for,(后跟时间段) since（后跟时间点或一般过去式的从句）等表示一段时间的时间状语连用。
- I haven’t seen him for a long time. / since he ________(离开)
- I haven’t heard from him for half a year.
- I haven’t borrowed books for two months.
4) 非延续性V. 可以转换为延续性V.，有以下几种情况：
用相应的延续性动词
buy—have; borrow—keep/have; put on—wear; catch(get) a cold—have a cold; come/go/become—be
转换成“be + n.”形式
join the Party—be a Party member join the army—be a soldier
go to school—be a student
转换成“be + adj./adv.”形式
die—be dead; finish—be over; begin—be on; leave—be away; fall asleep—be asleep; wake up—be awake; get up—be up; close—be closed; open—be open
d) 转换成“be + 介词短”语形式
go to school—be in school; join the army—be in the army
5)Practice：
他回来已三天了。____________________________________
他离家已有两个月了。_____________________________________
他父亲已死了三年了。__________________________________________
