Unit 9 Have you ever been to an amusement park Section B 3a-4导学案【学习目标】1.学习一些新词汇。 2.学会写有关个人学习英语的经历。【重点、难点】1. 语法：现在完成时。延续性动词和瞬间动词2.阅读、写作。【导学指导】温故知新用一分钟写出本单元你所学的新单词自主互助学习 小组学习Section B Activity 3a并完成文章后的问题。知识剖析：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。例如：1) I have studied English since last year. 我从去年开始学习英语。2) She has lived in Beijing for five years. 她住在北京已经五年了。3) We have already been here since we were born. 我们自出生就住在这儿。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.* I have received his letter for a month.可以说：He has been in Beijing for two years. He has had that book for three weeks. He has been in the army for one and a half years. His grandma has been dead for nine months.I havent received his letter for almost a month.或者： It is two years since he came to Beijing. 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 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。 重点句型 1. All I ever wanted to do was traveling. I ever wanted to do 是定语从句 我曾经想做的一切是旅行。 2. That the best way to do this was to become a flight attendant. That the best way to do this 是主语从句 做这个的最好方法是成为一个机组乘务员。 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, its all I have ever wanted to be. I have ever wanted to be 是一个定语从句 事实上，那就是我曾经所想的全部。【课堂练习】 ( ) 1. -_ you ever _ to an aquarium? -Yes, we had a good time there.A. Have, gone B. Had, been C.
