高考名词性从句考点主要有以下六个方面:
考点之一:考查名词性从句中that与what的区别
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. doris
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3: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that的区别
考例4: _______ we'll go camping tomorrow depends on the weather.
A. If B. Whether C. That D. Where
分析:句子的意思是:我们明天是否去野营要视天气而定. whether与if当"是否"讲时的区别是:在引导宾语从句时两者可以互换,但在引导主语从句、表语从句和同位语从句以及介词后面的宾语从句或后面紧跟or not时通常只能用whether,而不能用if.
考例5: What the doctors really doubt is _______ my mother will recover from the serious disease soon.
A. when B. how C. whether D. why
分析:本题句子的意思是:医生真正怀疑的是我母亲是否能很快从重病中恢复过来.whether引导的是表语从句.
It worried her a bit _______ her hair was turning gray.
A. while B. that C. if D. for
考点之五:考查名词性从句中的疑问词+ever引导的名词性从句及其与no matter+疑问词引导的从句的区别
考例 6 :It is generally considered unwise to give a child _______ he or she wants.
A. however B. whatever C. whichever D. whenever
分析:本题句子的意思是:一般认为孩子要什么就给什么是不明智的.whatever引导的是宾语从句,A. however 和D. whenever是不能作宾语的;而C. whichever表示"无论哪一个、无论哪些",表示在一定范围内的人或事物,此处并不涉及"一定范围内的人或事物",所以也不能选.
考例7: Sarah hopes to become a friend of ______ shares her interests.
A. anyone B. whomever C. whoever D. no matter who
分析:本题句子的意思是:萨拉希望跟自己有共同爱好的人交朋友.疑问词+ever引导的名词性从句与no matter+疑问词引导的从句的区别是:前者既可以引导名词性从句也可以引导让步状语从句;后者只能引导让步状语从句.首先排除D.而选A. anyone则应在其后加who.从句中需要的是主语,所以whomever也不行.
考点之六:考查名词性从句的虚拟语气问题
考例8 :It is necessary that a college student ______ at least a foreign language.
A. masters B. should master C. mastered D. will master
分析:句子的意思是:大学生至少应该掌握一门外语。It作形式主语,that引导的主语从句中谓语动词用虚拟语气。
(1) 在主语从句中用来表示惊奇、不相信、惋惜、理应如此等,谓语动词用虚拟语气"(should)
+do",常用的句型有:
I. It is necessary (important, natural, strange, etc.)
II. It is a pity(a shame, no wonder, etc.)
III. It is suggested (requested, proposed, desired, etc.) 如: It is strange that she (should) think so.
(2) 表示建议、请求、命令、要求、坚持等及物动词后面的宾语从句中要用虚拟语气,常用的这类动词有suggest, propose, insist, desire, demand, request, order, command等。如:
I insist that she (should) do her work alone.
(3) 主语是suggestion, proposal, request, decision等表示"建议、请求、要求、决定等"意思的词时,表语从句中谓语动词要用虚拟语气"(should) +do"。如:
His suggestion is that we (should) hold another meeting to discuss the question.
(4) 表示"建议、请求、命令、要求、决定等"意思的名词后面的同位语从句中谓语动词要用虚拟语气"(should)+do"。如:
They received orders that the work(should)be done at once.
