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。谓语动词为延续性动词，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:

1. He has come back. (   )___________________________________
2. He has come back for 3 days. (   )___________________________________
3. I have borrowed the book. (   )___________________________________
4. I have borrowed the book since last week.  (   )____________________________
5. I have got up for an hour. (   )____________________________
6. 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。

1. I haven’t seen him for a long time. / since he ________(离开)
2. I haven’t heard from him for half a year.
3. 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。__________________________________________

他已睡了一小时了。__________________________________________

这场电影已经开始一小时了。___________________________________________
