状语从句教案.doc

状语从句（2h）教学目标：掌握9大状语从句及其中重要的引导词与句型。由于高考中状语从句经常和从句的时态语态，动词短语的搭配，以及状语从句的省略，虚拟语气与倒装一起考查。因此必须掌握好：1 时间状语从句中各种引导词引导的主句与从句的时态的判断2 地点状语从句中表示抽象含义时从句必须在主句之前3 原因状语从句中because，as，now that的位置问题4 目的状语从句中的so that与在结果状语从句中的区分5 结果状语从句中的so/suchthat的特殊结构及其倒装6 条件状语从句中的if，unless的用法7 方式状语从句中的虚拟语气的用法8 让步状语从句中的as, though做引导词时的倒装用法教学重点：1 掌握常用的状语从句中的引导词 2 判断状语从句中的时态 3 状语从句中的倒装情况：no soonerthan, hardly/scarcelywhen, notuntil用于句首时的倒装；结果状语从句中so/such置于句首时的倒装情况；as/though引导的让步状语从句的倒装情况 4 as if/though引导的方式状语从句中的虚拟语气教学进程：导入：状语从句在句子中作状语，修饰谓语。时间状语从句回顾有哪些词可以引导时间状语从句when, while, as表示“当时”; immediately, instantly, as soon as, directly, the moment, no sooner than, hardly when, scarcely when, once表示“一就”； till, until, not until表示“直到才”；before 表示“还没来得及就”，“不到就”；since表示“自从”；every time, each time, next time, the first time, any time, all the time表示“每当”，“每次”，“下次”等等状语从句中的时态的判断方法：过去，现在，将来延续性与非延续性/时间点与时间段主从句中的谓语动词的先后关系判断开始时间与截止时间 when, while, as都可以表示主从句动作同时进行(口头造句举例)如：when the music fades away, people tide away.She sat there alone while others were all dancing.He dances joyfully as the music goes.当主句动词为短暂性，从句动词用延续性动词的进行时态表示一段时间内的动作时，三个词可互换。如上面的第二个句子。When可引导持续动作亦可引导短暂动作。如When I was young, I used to play Barbie dolls.While引导的必须为延续性动词，侧重和主句中的动词相对比。如While he was making the breakfast, his wife was sleeping.As可以指主从句的动作交替进行。如She feels someones following her, so she walked fast as lotoked back.“一就”The moment she heard the music she liked most, she stood up to dance.Hardly had the Cinderella got home when the clock knocked 12 oclock.As soon as I get there, Ill let you know.(强调当no sooner than和hardly when, scarcely when提到句首时要用到倒装)till, until, notuntil肯定句：主谓语必须为延续性动词You can dance to your joy until you feel tired.否定句：主从句必须为非延续性动词You cant marry him until I say yes.（强调till不能放句首，until可以）6. beforeI hadnt finished my sentence before he turned his back to me。It will be 2 years before I get back.7. sinceI havent spoken to him since 1 year ago.It is 3 years since I smoked.It has been 3 years since I smoked.8Every time歌词：every time I leave to head out on the road, I wanna take you with me, save me from the cold.练习：1 We usually call someone a green hand _(当他没有经验)his job.(experienced)2 I was speaking to Ann on the phone_（突然我们短线了)(cut)地点状语从句表示抽象含义时，从句需在主句前。如Where there are girls, there is gossip.where引导的定语从句与状语从句Youd better make a mark where you have any questions.（状从）Youd better make a mark at the place where you have any questions.
