名词性从句经典例句
所谓名词性从句包括主语从句和宾语从句，现各给你举一个例子。What he said made me very angry.(what he said是主语，made是谓语，me是宾语，angry是宾补）He said that he was from America.（第一个he是主语，said 是谓语，that引导的句子时宾语）
名词性从句语法总结思维导图
名词性从句，就是一个句子（从句）在另一个句子（主句）中做主语、宾语、表语、同位语、介词宾语等，相当于名词的用法。名词性从句根据在句子中所做的成分又可分别称为主语从句、宾语从句、表语从句和同位语从句。
名词性从句的引导词
连接代词：what,which,who,whom,whose
连接副词：when,where,why,how
连接连词：that（宾语从句或表语从句中“that”有时可以省略）；whether,if（均表示“是否”表明从句内容的不确定性）；as if,as though（均表示“好像”，“似乎”）
名词性从句的时态问题
1.当主句的谓语动词是过去式时，宾语从句若不是一个客观事实或真理，其谓语动词也必须用某种过去时态。如：
She said that she didn't want to know.她说她不想知道。
I asked her whether she would agree.我问她是否会同意。
2.when, if 这两个词既可引导名词性从句，也可引导状语从句。当它们引导名词性从句且表示将来意义时，要直接使用将来时态;但当它们引导状语从句且表示将来意义时，则必须用一般现在时表示将来意义。如：
I don't know when he will come, but when he comes,I'll call you.我不知道他什么时候，但当他来的时候，我会打电话给你。
句中第一个when引导的是宾语从句，故用将来时态表示将来意义；第二个when引导的是时间状语从句，故用一般现在时表示将来意义。
whether与if 引导名词性从句的区别
whether与if 均为"是否"的意思。但在下列情况下，只可用whether：
1、whether引导主语从句并在句首。
例：Whether he can come to the party on time depends on the traffic.
2、引导表语从句。
例：The question is whether we can get in touch with her.
3、whether从句作介词宾语。
例：I am thinking about whether I should quit my present job.
4、if与whether都可以与or not连用，但后面紧跟or not时只能用whether。
例：We didn't know whether or not she was ready.(此时只能用whether)
名词性从句各种分别举两个例子英语
一个句子起到名词作用,就是名词从句.名词从句有主语从句,表语从句,宾语从句,同位语从句.同样的,一个句子起到定语作用,就是定语从句,修饰一个名词.
几个名词从句的例子：
What he said is right.（主语从句）
I didn't know where he would hold the party.(宾语从句)
The reason for his being late was that he got up late.( 表语从句)
The fact that he is a policeman surprises us.(同位语从句)
几个定语从句的例子：
Thy boy who is standing there is my brother.
I don't like the way in which he talks to his parents.
The reason why he was late was that he got up late.
