名词性从句包括主语从句、宾语从句、表语从句和同位语从句.名词性从句一向是NMET中的重要考点.通过对近几年高考试题的分析,我们可以看出NMET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
考例: _______ we can't 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
分析:在名词性从句中,除了关联词要提到句首之外,一律要用陈述句语序。当关联词含疑问意义时,有的学生就会受习惯影响错误地使用疑问句语序。克服这种错误的关键是要找准从句中的主语和谓语。本题句子的意思是:这些照片会告诉你我们村子是什么样。本题中根据引导词what要作介词like的宾语,而副词how不能作介词like的宾语,所以首先排除C、D,而A项是疑问句语序,故只能选B。
考点之四:考查名词性从句中的whether, if以及that的区别
考例1: _______ 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2: 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.
考例3: It worried her a bit _______ her hair was turning gray.
A. while B. that C. if D. for
分析:本题句子的意思是:头发变白使她有点儿不安。It作形式主语,that引导的是主语从句。whether, if以及that引导的名词性从句的区别是:whether与if(当"是否"讲时)引导的名词性从句含有疑问意义;而that引导的名词性从句不含有疑问意义。
