英语语法 名词性从句的考查及复习.ppt
高三英语总复习语法系列训练,从高考试题谈名词性从句的 考查及复习,语法：名词性从句 名词性从句相当于名词，可分别做主句的主语、表语、宾语和同位语。因此，名词性从句可分为: 主语从句：What you said sounds reasonable. 表语从句：This is what I was asked to do. 宾语从句：Nobody knows who broke the glass. 同位语从句：The idea that well go out for a picnic is great.,引导名词性从句的连词： 1. 从属连词：that (无词义，在句中不充当任何成分) if / whether (有词义“是否”，但不充当任何成分) 2. 连接代词：who, whom, whose, what, which, whatever（有词义，在句中充当主语、表语、宾语或定语） 3连接副词： when, where, why, how, how many, how long, how far, however, whenever, wherever （有词义，在句中充当状语）,名词性从句应注意事项： 1名词性从句的语序为陈述句 除What is / was the matter（ the trouble、wrong ）with you ? 外 2从属连词that不充当任何成分。That he will go to the USA is known to his friends. 3What, whatever总是要充当主语、宾语、表语和定语 What country are you from ?,4 If 和whether 的区别： If 引导条件状语从句和宾语从句及 it 做形式主语的主语从句 如：It has not been decided if/whether we will have another three days off. Whether 引导宾语从句、主语从句、表语从句和同位语从句。,当 if 和whether 引导宾语从句的区别，即用 whether不用if 的情况： (1) 作介词宾语 It depends on whether it is fine. (2) whether +to do Im not sure whether to leave this afternoon. (3) whether or not He can not decide whether or not take the exam.,4. doubt 用于肯定句中，宾语从句可以用if 或whether 引导。 I doubt if (whether)you will come for a visit tomorrow. doubt 用于否定句或疑问句中，宾语从句用 that 引导。 He doesnt doubt that his mother will give him a ride home .,5.whatever, however, whichever, whoever, whomever, 既可以引导名词性从句，又可以引导状语从句；而 no matter what, no matter how, no matter which , no matter who, no matter whom只可以引导状语从句 Whatever (No matter what) difficulty we meet, well never give it up (状语从句) You are free to get whatever you want to . (宾语从句),6. as if (though) 既可以引导表语从句, 又可以引导状语从句 He is walking as if he were drunk (状语从句) It looks as if it is going to rain. (表语从句),7. 由于主语从句、宾语从句较长，为此多将主语从句、宾语从句放在句末，用it 做形式主语或形式宾语。 It has been decided when we will have a field trip. ( 主语从句 ) We found it necessary to have a good knowledge of history. ( 宾语从句 ),名词性从句专练,1.
