高考英语精讲精练课件; 名词性从句;为什么叫名词性从句？ _______________________; 主语从句; It 作主语的常用句型有:; 用形式主语 it 的主语从句常见结构;用 it 句型翻译:;表语从句;注意下列表语从句中where, how, why 的译法;宾语从句中的连接词that在以下三种情况下不能省略： （1）当that 从句与另一名词性从句并列作宾语时，第二个that不能省； （2）当that作介词宾语时，that不可省掉。 （3）用it做形式宾语的宾语从句 Everyone knew what happened and that she was worried. The reason lies in that she works harder than the others do.;whether与if的辨用;1).whether和if都可以引导宾语从句 a..当whether后紧跟or not时,不用if. eg: I don’t know whether or not I will stay. b.介词后面的宾语从句不能用if. eg: I worry about whether I hurt her feeling.;Practice time;I doubt if / whether he will pass the exam. I don’t doubt that we will win the match. Do you doubt that he did it on his own? ; 宾语从句经常做介词的宾语;;correction;同位语从句;;4.Time travel is possible./ There is no scientific proof for the idea.;一、同位语从句与定语 从句的相似之处;2、两种从句都可以用that引导 e.g. ;二、同位语从句与定语 从句的不同之处;2、引导从句的关联词that的功能不同：that引导同位语从句时是一个纯连词，不充当任何成分；而引导定语从句的that是关系代词，既指代先行词又须在从句中充当成分。;考点之一:考查名词性从句中that与what的区别 　　考例: _______ we cant get seems better than _______ we have. 　　A. What; what B. What; that 　　C. That; that D. That; what 　　分析: (注:划线的选项为最佳答案,下同.)在名词性从句中that与what的区别是:that在名词性从句中不作句子成分,只起连接作用;而what在名词性从句中不仅起连接作用,而且作句子成分.句子的意思是:我们不能得到的似乎比我们已经拥有的要好.此题考查了两个名词性从句:主语从句和宾语从句,what在这两个名词性从句中都作宾语. ;考点之二:考查名词性从句中的it作形式主语或形式宾语 　　考例1: _______ is a fact that English is being accepted as an international language. 　　A. There B. This C. That D. It 　　分析:在这种名词性从句中为了保持句子的平衡,往往用先行词it作形式主语或形式宾语,而把真正的主语或宾语放到后面,尤其是that引导的主语从句往往用先行词it作形式主语.此句也可以改写为:That English is being accepted as an international language is a fact. 　　考例2: I hate _______ when people talk with their mouths full. 　　A. it B. that C. this D. them 　　分析:此题考查的是用先行词it作形式宾语,而把真正的宾语从句放到后面.其他几个词均不能作形式宾语. ;考点之三:考查名词性从句的语序 　　考例:The photographs will show you _______ . 　　A. what does our village look like 　　B. what our village looks like 　　C. how does our village look like 　　D. how our village looks like ;考点之四:考查名词性从句中的whether, if以及th
