高一英语语法（名词性从句）
一、概述
在句子中起名词作用的从句称为名词性从句。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。
二、名词性从句的引导词
1、连接代词：who, whom, whose, what, which, whoever, whatever等
2、连接副词：when, where, why, how3、从属连词: that, whether, if, as if, because(as if, because 只引导表语从句)连接代词和连接副词在句中不再是疑问词，因而从句中用陈述语序。
三、主语从句
1、主语从句用连接代词、连接副词和从属连词that,whether引导。
That you don’t like him has nothing to do with me.____________________________________________(约翰是否会做这个实验)remains a question.Who will be sent abroad to further his studies is not announced._____________________________(使我大为惊讶的)was that such a little girl can play the violin so well._________________________________(她是否会告诉我真相)is not known yet.______________________________________________(她如何设法在这么短的时间内完成这篇作文)is still a mystery.2、当主语过长时，常常用it作形式主语，而把真正的主语从句放在主句后面。常用句型有： 1)It +be +形容词（true, poible, certain, likely, surprising, strange, important…）+ that从句
It’s certain that she will do well in the exam.It’s likely that he will tell me everything about that night.It’s strange that he should speak to his mother in such a way.2)It +be +名词词组（no wonder, an honor, a pity, high time等）+that 从句
It’s a pity that he can’t come.It’s high time that you turned in your homework.3)It +be +过去分词（said, reported, expected, supposed等）+that 从句
It’s said that he is quite self-confident.It’s reported that a letter from the university has reached him.4)It +seem/ happen/look as if等+that从句 t It seems that Alice is not coming.It happened that I was a witne to the accident.5)It +doesn’t matter(make no difference)+wh-It doesn’t matter whether you know my name or not.It makes no difference to me where we shall have the meeting.四、表语从句
表语从句用连接代词、连接副词和从属连词that, whether, as if, because引导 The impreion he makes on me is________________________(他是个可靠的人。)The question is ______________________(我们是否能信任他)That’s ____________________________(正是我们所担心的)
