语法填空名词性从句

高考语法填空名词性从句专题训练解题技巧：1名词性从句中连接词的选用应该遵循“语义是否完整，所填部分充当什么成分”的原则。语义完整选用连词：that, whether, if；连接代词who, what, which , whom, whose, whatever, whoever, whomever, whichever在名词性从句中作主语、宾语；whose作定语，后面接名词。连接副词：when, where, how, why, however, whenever, wherever在名词性从句中作状语。2. that与whether引导名词性从句的区别。that与whether都是连词，引导名词性从句时，在句中只起连接作用，都不担任句子成分，使用时有下列区别：（1）that本身无意义，仅起连接作用，有时可以省略；whether本身有意义，意为“是否”，表明从句意义的不确定性，在句中均不可省略。（2）如果宾语从句表示两种可能性选择其一时，只能用whether(or not)，不可用that。（3）whether引导的从句能几乎作所有介词的宾语；that引导的从句只能作except, but, besides的介词宾语。3. whether和if的区别。（1）whether可以引导介词宾语从句，而if不能。（2）whether可以应到所有的名词性从句，而if只能引导宾语从句；在引起主语从句时，特别是主语从句在句首时，不能用if，除非是有形式主语it的主语从句。（3）whether后可以直接跟or not，if则不能。（4）whether可以和不定式连用，而if不能。（5）whether or可以引导让步状语从句，or不可省略；if可以引导条件状语从句。做得更好。4. 连接代词与连接副词的区别。（1）wh-ever引起的名词性从句不含疑问意义，相当于不定代词后加一个定语从句：whatever = anything that，whoever=anyone who, wherever=any place where, whenever=any time when表示泛指；而what，which，who，when，where，how等词都有时含有疑问意义，表示特指。（2）介词后的who/whom，whoever/whomever的选择问题，则要看连接词在从句中是作主语还是作宾语而定，如在从句中作主语则只能选用who/whoever。（3）正确使用who/ whoever，what/whatever，how/however，where/wherever，when/whenever，which/whichever，who，what，where，when，how，which一要分析句子结构，看其在从句中作何成分，二是理清其在句中的含义。一、观察分析从句结构，选用适当的连词完成下列句子。1.
