【公开课教案】高三英语语法专题复习之状语从句

高三英语语法专题复习之状语从句教材内容分析本课是进行高三英语语法的复习,我在教学中将语法知识的传授和语言基本技能的学习结合到一起,注重复习语法与语言的运用。

采用任务型教学法和小组合作探究学习法,从而扩大课堂的语言输入量及学生的语言输出量。

教学目标1、知识与技能引导学生准确把握非状语从句的使用。

根据该语法规律解决实际问题。

在运用语言的过程中培养学生的观察力、分析力、想象力和自学能力,帮助学生加强记忆力,提高思维能力和运用英语的综合能力,激发创造能力。

2、过程与方法以学生为主体,尝试创新思维,联系社会采用讨论、协作、探究、竞争的教学模式,引导学生灵活运用所学语法知识3、情感、态度的价值观。

用状语从句的句子结构表达思想感情和正确的世界观、人生观。

形成健全的情感态度,为未来发展和终身学习奠定好的基础。

教学重难点1)教学重点:了解和掌握状语从句的使用。

2)教学难点:能够运用此语法规则完成各种练习训练,并在实际语言活动中灵活运用。

一.状语从句的定义:在复合句中由从句表示的状语称作状语从句,它可以用来修饰谓语(包括非谓语动词)、定语或状语,或是整个句子。

状语从句通常由一个连词引起,也可以由一个起连词作用的词组引起,有时甚至不需要连词直接和主句连接起来。

状语从句一般分为九大类时间状语从句地点状语从句原因状语从句目的状语从句结果状语从句条件状语从句方式状语从句比较状语从句让步状语从句二.状语从句的分类:1.时间状语从句:在时间状语从句中,要注意时态一致,一般情况下主句是将来时的时候,从句要用一般现在时。

可以引导时间状语从句的连词很多,根据意义和主从句之间的时间关系,又可分类如下:(1)表示同时性,即主从句的谓语动作同时发生或几乎同时发生。

其连词有:when (当……的时候), while(当……的时候), as(当……的时候), once(一旦……)as soon as(一……就……), the time(当……的时刻), the moment(当……的时刻), by the time(到……时候为止), next time(下次), the first time(第一次……的时候), the last time(上次……的时候),immediately(一……就……), instantly(一……就……),directly(一……就……)以下关联词引起的句子中,前面常用过去完成时,后面用一般过去时hardly /scarcely…when…(刚……就……), no sooner…than…(刚……就……)Strike while the iron is hot.趁热打铁。

④until引导的从句可以放在主句之前或主句之后,但till从句一般不放在句首。

如:Until he told me, I knew nothing about it.他告诉我了我才知道。

当not until位于句首时,主句中的主语、谓语要使用倒装语序:Not until she came back did I leave. = I didn’t leave u ntil she came back.在强调句型中一般用until,不用till。

如:It was not until she took off her dark glasses that I realized she was a famous film star.地点状语从句是由where(在……的地方), wherever(无论哪里)引导的:Wuhan lies where the Yangtze and the Han River meet.武汉位于长江和汉水汇合处。

Where there is a will, there is a way.有志者,事竟成。

You’d better make a mark where you have any questions.(这里where引导的从句不是定语从句) 哪儿有问题,你最好在哪儿做个记号。

He would keep in touch with us wherever he was.他无论在什么地方,总是与我们保持联系。

表示原因的状语从句可以由as(由于),because(因为), since(既然),now (that) (既然), for (由于)considering that(顾及到), seeing that(由于)等连词引导:I do it because I like it.因为我喜欢我才干。

(because不能与so连用)He co uldn’t hav e seen me, because I was not there.他不可能见过我,因为当时我不在那儿。
