英语名词性从句学习要点汇总（三）

名词性从句是在句子中起名词作用的句子。 名词性从句的功能相当于名词词组， 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

引导名词性从句的what

1、引导名词性从句的what在从句中作主语、宾语、表语或定语。what有时具有疑问代词的性质，意为“什么”“什么样的”；有时具有关系代词的性质，意为“所……的”，相当于“先行词＋关系代词that”，即相当于“the＋名词＋that”或all that。

2、相当于疑问代词Do you know what his sickness is? 你知道他患什么病吗?Look about and tell me what you see. 向四周望望，告诉我你看到了什么。

3、相当于“先行词+关系代词”What he had hoped at last came true. 他希望的事最后实现了。He was deeply touched by what she said. 她的话深深触动了他。We can learn what we did not know. 我们可以学会我们不知道的东西。

–ever引导的名词性从句

1、这些词包括whate箪滹埘麽ver, whoever, whichever等，它们可用于引导主语从句和宾语从句。其中whatever大致相当于anyt茑霁酌绡hing that或what，但语气比what更强；whoever大致相当于anyone who；whichever大致相当于any that或any…that。如：I will just say whatever comes into my mind. 我想到什么就说什么。Whoever breaks the rules will be punished. 谁违反这些规则都将受到处罚。I’ll give the ticket to whoever wants it. 请想要这票，我就把它给谁。Whichever team gains the most points wins. 哪个队得分最多，哪个队就赢。Whichever of us gets home first starts cooking. 我们当中无论哪个先到家，哪个就先开始做饭。

“疑问词＋do you think＋从句”类句型

1、当think, believe, suppose等的疑问式后接疑问词(连接代词和连接副词)引导的宾语从句时，习惯上将疑问词置于句首。如：What do you think she would feel? 你想她会有什么感觉?How long do you think you’ll be gone? 你想你会离开多久?What do you think the result will be? 你认为会产生什么样的结果?When do you think it can be operated on? 你想什么时候可以给它动手术?注：有时what do you think…后接的不是一个从句，而是句子的谓语，此时do you think可视为一个插入成分。如：Which idea do you think is best? 你认为哪个主意最好？Who do you think will win on Saturday? 你认为星期六谁会赢?
