1、Module 8 Unit 1 A land of diversity 语法课单元语法：复习名词性从句主语从句、表语从句和宾语从句学习目标：掌握名词性从句中主语从句、表语从句和宾语从句在句子中作为主语、表语和宾语的用法。重点语法解说：名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句可分为主语从句、表语从句、宾语从句和同位从句。（1） 引导名词性从句的连接词1、 连接代词：who,whose,whom,what,which,whoever,whatever有词义，在从句中担任成分，如主语、表语、宾语、或定语等。2、连接副词：when,where,why,how。有词
2、义，在从句中担任成分，作状语。3、连接词：that,whether,if,asif。that无词义，在从句中不担任成分，有时可省略；if(whether),asif虽有词义，但在从句中不担任成分。 注意：连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether和if（是否），asif（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if和asif都用不上时，才用that作连接词（that本身无任何含义）。（2） 主语从句1、 主语从句在复合句作主语。Whowillgoisnotimp
3、ortant. What you have to do is to choose a company to invest in.When we will start is not clear.2、有时避免头重脚轻，可用it作形式主语，主语从句放在句末。 Itdoesntmattersomuchwhetheryouwillcomeornot.Its a pity that he didnt finish college.3. that引导主语从句时，不能省略。 Thathesuddenlyfellilllastweekmadeussurprised.（3） 表语从句表语从句在复合句中作表语，位于
4、系动词之后。Thequestionwaswhocouldgothere. That is why I was unwilling to go yesterday.She looks as if she was ill.（4） 宾语从句1、宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。Ihope(that)everythingisallright.I want to know when class begins.2、 介词之后的宾语从句，不可用which或if连接，要分别用what或whether。Iminterestedinwhetheryouvefinishedthewor
5、k. She was never satisfied with what she had got. 3、 whether与if都可以引导宾语从句，常可互换。但下面情况不能互换。 宾语从句是否定句时，只用if，不用whether。Iwonderifitdoesntrain. 用if会引起误解，就要用whether。 Pleaseletmeknowwhetheryouwanttogo.（此句如果把whether改成if，容易当成条件句理解） 宾语从句中的whether与ornot直接连用，就不能换成if；不直接连用，可换。I dontknowwhetherornotthereportistrue.
