高二选修七模块二名词性从句

2.注意点
1).引导词that无实际意义,但不能省略. 2).只能用whether,而不能用if 引导. .注意:在表语从句中,当reason做主语时, 引导词只能 用that,不能用because,如:他迟到的原因是因为他没有 赶上早班车。 The reason why he was late was that he didn’t catch the early bus. 4. because It/ This/That is because… 那是因为…… He was late. That was because he was ill.
动词宾语、介词宾语、形容词宾语
注意1. 【有些动词不能直接跟 从句】
dislike, love, depend on,
help, take, like, hate, see to(负责,注意,照 料), appreciate+ it +从句….
Never take __B______for granted that I will help you. Better depend on yourself. A. that B. it C. which D. his
2).连接词that在从句中无实际意义,但不能省略. 例: 误: He will not come is true.
正: (That he will not come) is true.
3).whether可以引导主语从句,但if不能. 【it-主语从句】 有时为避免句子头重脚轻，常用it 代替主语从句作形 式主语放于句首，而把主语从句置于句末。主句的谓 语动词一般用单数形式。常用句型如下：
1.他是怎么成功的仍然是个谜。 How was he successful is still a puzzle. ( F ) How he was successful is still a puzzle. ( T )
It depends on whether he is coming or not . 这要看他是否会来。
c. 后接动词不定式时。 Can you tell me whether to go or to stay? 你能
否告诉我是去还是留？
（三）表语从句
【定义】 在句中充当表语的从句叫作表语从 句．
It is ＋名词＋从句 it is ＋形容词＋从句 it is＋过去分词＋从句 it ＋不及物动词＋从句 it ＋动词短语（make （no） difference）＋从句
It is well known /reported / thought/said… that… It is clear/ necessary/ certain/ true…that…
It is a pity/a shame/an honour/no wonde that…
It seems/happens/appear that… It that… It doesn’t matter/makes no difference
whether…
四、将主语从句变为简单句
一、句型“It happens /seems that 主语+谓语动词+…”用“主 语+happen/seem + 不定式” 例如：
B
2、 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
陈述语序
判断下列句子是否正确，（T or F）
2) 连接代词：what, who, which, whose, whatever, whoever, whomever, whichever
3) 连接副词：where, when, why, how,
（一）主语从句 【定义】
在句中充当主语的从句叫做主语 从句．
二.主语从句
注意点
1).主语从句一律用陈述句语序,即主语在前,谓 语在后. 例: 误: When will he come is not known. 正: (When he will come) is not known.
That they will come ______certain. What he wants _____ some water. What he wants _____these books.
【结论】 主语从句通常被看作一个整体,主句的谓语动词用 单数形式. What 引导主语从句时,主句谓语动词的单复数由 表语的单复数决定.

• When and where we’ll hold the meeting has not been
decided yet. （when & where 指开会的时间和地点，属 同一件事）
注: 1. 同谓语从句多用that/whether 引导 2. 在have no idea 之后常用wh-引导同位语从 句.
