高中英语高考名词性从句高频考点易混点整理(含练习和答案)
高考英语名词性从句高频考点易混点高频考点一：考查that与what的区别在引导名词性从句时，从属连词that一般要注意三个"不"：1.不省略。
当从属连词that引导的主语从句位于句首时，that不省略；that引导同位语从句时，一般不省略。
2.不作成分。
that 在名词性从句中不作任何句子成分。
3.无实义。
that 在名词性从句中没有实义。
在引导名词性从句时， what一般要注意一个"不",一个"有词义",一个"作成分"：1.不省略。
what 引导名词性从句时，不省略。
2.有词义。
what 引导名词性从句时，有词义。
一般表示"……的东西/事情等"，这一用法与that 的用法不一样。
3.作成分。
what 在引导名词性从句时，在从句中充当成分。
这一用法与that 的用法不一样。
例如：Nobody believed his reason for being absent from the class that he had to meet his uncle at the airport.该句中，that引导同位语从句，在句中不作任何成分，不能省略且无词义。
What the teacher said had a good effect on the children.what引导主语从句，在句中有词义。
高频考点二：it放在句首，真正的主语是that从句常用句型如下：① It+系动词+n.+ that从句;② It+系动词+adj.+ that从句;③ It+be+动词的过去分词形式（如said, reported, suggested等）+that从句；④ It+特殊动词（appear, seem, happen, matter, turn out, work out等）+that从句。
高频考点三：考查whether与if的区别whether与if在作"是否"讲时,是可以互换的。
定语从句与易混淆句型
Let’s have a try at once
• She expressed the hope that they would come to visit China again.
同位语从句：they would come to visit China 对hope 进行具体的解释说明。
• The hope that she expressed is that they would come to visit China again.
4. (1) Is this school __D___ you ever visited? (2) Is this the school __A___ you ever studied? (3) Is this the school in __B___ you ever studied? A. where B. which C. that D. the one
定语从句与并列句的主要区别： 并列句有像and，but，so等并列连词 或两个句子用分号连接， 这时就不能再用引导定语从句的关系词了。
Practice:
① Mr. Smith made a lot of money，
most of ____ was spent helping the poor．
②It is the factory w__h_e_re_ Mr. Wang works．
强调句的结构为: “It is／was＋被强调部分＋that＋从句” 强调句检测的标准： 先把It is／was, that去掉，再把被强调部分还原， 在不增加或减少任何单词的情况下， 如句子仍然成立则为强调句，否则为定语从句。

定语从句和名词性从句易混点和练习(答案)
定语从句和名词性从句易混点讲解和练习定语从句（Attributive Clauses）定语从句是在复合句中修饰名词或代词的句子，由关系词（关系代词或关系副词）引出。
e.g. She is the girl who talked to me yesterday.名词性从句名词性从句相当于一个名词的功能，根据其在主句的功能作用又可分为主语从句、宾语从句、表语从句和同位语从句。
分类如下：主语从句：What he told me is a secret.宾语从句：I have forgotten what he told me.表语从句：That is what he told me.同位语从句：The news that we won the match was true.引导词总结如下表：用法区别：第一，定语从句有先行词，且先行词可以放入后面的从句中使从句完整；名词性从句中的主语从句、表语从句和宾语从句没有先行词第二，名词性从句和定语从句的最本质的不同点在于，前者在句子中做名词，而后者相当于形容词，修饰或限制名词或代词。
名词性从句由that引导时，通常不充当从句的句子成分，故that可省去。
但定语从句由that引导时，如在从句中充当主语时，则that不能省去。
I know (that) he is to blame.We all know the story that was told by our teacher.第三，使用中最大的区别：定语从句由于在句子中只作定语，故去掉它，整个句子还完整，就像普通的句子去掉一个定语不影响原句的完整性一样。
但名词性从句由于它们充当的是句子的骨干成分（主语，宾语或表语），故去掉它们，原句就不通了。
The boy who has a surprised look is sitting there.Who will come here is unclear.注：用于同位语从句的名词通常有hope, fact, truth, belief, news, idea等抽象名词。
