How long have you had that bike ? Ive had it for three years. 2. I learned how to ride a bike on it. 3. Amy wants to keep her old things because they bring back sweet memories.【教学难点】现在完成时与for和since连用的用法。（延续性动词）【学情分析】本课时是在学生已学第七、第八单元的基础上，进一步学习现在完成时的延续性用法。学习延续性动词与for（后跟一段时间连用） ,since（后跟时间点，或一段时间+ago/或一般过去时的从句连用），学生已有一定的学习基础。本节课要让学生达到熟练掌握单词与词组，熟练掌握how long提问一段时间的用法，区分短暂延续性与非延续性动词，延续性与非延续性动词之转换规律。相信学生学习难度不会特大。Step1 ExercisesStep 21. 让两名学生表演1a中对话2. 1b部分先让朗读并翻译，听第一遍，让学生勾出所听事实，听第二遍，让一名学生说出答案。听第三遍，让学生朗读并模仿该对话。3. 让两名学生示范表演1c中对话，让学生两两对话Step3 质疑：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。 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buyhave; borrowkeep/have; put onwear; catch(get) a coldhave a cold; come/go/becomebe 转换成“be + n.”形式join the Partybe a Party member join the armybe a soldiergo to schoolbe a student转换成“be + adj./adv.”形式diebe dead; finishbe over; beginbe on; leavebe away; fall asleepbe asleep; wake upbe awake; get upbe up; closebe closed; openbe opend) 转换成“be + 介词短”语形式go to schoolbe in school; join the armybe in the armyStep4Exercise1)判断正误如有错误并改正:1.

He has died for 10 years. ( )_2)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 havent seen him for a long time. / since he _(离开)2. I havent heard from him for half a year.3. I havent borrowed books for two months.一选择题( ) 1. -_ you ever _ to an aquarium? -Yes, we had a good time there.A. Have, gone B. Had, been C.
