【导学指导】
温故知新（A）
用一分钟写出本单元你所学的新单词
自主互助学习（A.B）
小组学习Section B Activity 3a并完成文章后的问题。
知识剖析：(B.C )现在完成时动词可以表示1.开始于过去持续到现在的动作或状态。
2.也许还会继续进行下去的动作或状态。
有延续性的动词可以和表示一段时间的时间状语
连用。He has worked in the bank for 5 years.
work是延续性动词，可以和for 5 years连用。
而瞬间动词不可以和表示一段时间的时间状语连用。如果要表示其延续，可以用be动词。例如，不可以说He has come for 2 hours. come是瞬间动词。可以说He has been here for 2 hours.他在这里呆了两个小时。
( )2. Who ___________ this lonely place?
A. see B. discovered C. invented D. found
完成句子。
e to this school and _______________________________ (改变你的生活)
注意：come, go , leave, arrive, buy, lose, receive, join, die, bury和marry等动词所表示的动作是一时的，不能延续的，故不能与for…，since…等开头的表示一段时间的状语连用。不过，这些词用于否定句则可以与表示持续的时间状语连用，即动作的不发生是可以持续的。
例如：不能说：*He has come to Beijing for two years.
*He has bought that book for three weeks.
*He has joined the Army for one and a half years.
*His grandma has died for nine months.
3. It was because I could speak English that I got the job.这是个强调句型
正是因为我能讲英语，我得到了这个工作。
It is / was＋被强调的部分＋that / who＋其他部分
4. In fact, it’s all I have ever wanted to be. I have ever wanted to be是一个定语从句
It is three weeks since he bought that book.
It is one and a half years since he joined the Army.
It is nine months since his grandma died.
延续性动词和瞬间动词(C)
* I have received his letter for a month.
可以说：
He has been inBeijingfor two years.
He has had that book for three weeks.
He has been in the army for one and a half
