请思考

起定语作用，用来修饰名词或代词的从句。

1.名词:
表示人或事物的名称的词叫名词。
2.名词在句子作什么成分
名词在句中主要作主语、宾语、表语和同位语。
因此，名词性从句可分为主语从句、表语从句 、宾语从句和同位语从句。

作动词的宾语
作介词的宾语
作形容词的宾语
某些表示心理状态的形容词在句中作表语时，后面可跟宾语从句。
It 作形式宾语
it 不仅可以作形式主语，还可以作形式宾语，而把作真正宾语的that从句放在句尾，特别是用在带复合宾语的句子中。
I think it quite clear that he preferred coffee to tea.
I think it best that you should seek for a solution to the problem.
在口语或非正式文体中，引导宾语从句的连词that 常可省略。但形式宾语it后面的that 不能省略。
表语从句
表语从句位于连系动词后,有时用as if引导。
其基本结构为:主语 + 系动词 + that从句。
1. be, look, remain, 等系动词后均可跟表语从句：
My suggestion is that we should go shopping.
2. as if 也可引导表语从句。
It looks as if it’s going to rain.

请判断出下列的句子属于哪种从句
连接副词（4个）：when、 why、where、 how
引导词
从属连词（3个）：that 、if、 whether
连接代词 （9个）：who、 whom 、 what、 which、 whose、 whoever whomever、 whatever、 whichever、
名词性从句引导词的用法（1）：
从句中的每一个引导词都有3个功能，分别如下:
从属连词
“that”---无词义，表示事实、不作成份、起连接作用
“if”--- “是否”、不作成份、起连接作用
“whether”---“是否”、不作成份、起连接作用
If 只能引导两种名词性从句：宾语从句、不放于句首的主语从句。Whether四种从句均可以引导。
If与whether的区别：
1、Whether she will come back on time depends on weather .
2、I asked him whether he could do me a favor .
请思考：
1、It depends on weather / if she will come back on time .
2、I asked him if he could do me a favor .
1、If 只能引导两种名词性从句：宾语从句、不放于句首的主语从句。Whether四种从句均可以引导。
2、whether可以引导从句作介词的宾语，不用if 。
3、whether or not 连在一起可以，但if不可以。而“whether-----or not = if -----or not”
They have two weeks to decide whether or not to buy.
I don't know whether/ if he was right or not.
4.直接加动词不定式只能用whether （to do）
I don't know whether to go to hospital.
If与whether的区别：
1.______ we will hold a party in the open air
tomorrow depends on the weather.
3. I don’t know ___________ he is well or not.
4. I don’t know ________ or not he is well.
Whether
whether/if
whether
请用if / whether填空：

“whom”---“谁”、作宾语、起连接作用
“what”---“事情”、作主表宾、起连接作用
“whose”---“谁的”、作定语、起连接作用
“which”---“哪----”、作定语、起连接作用

3.从句描述客观事实，自然真理时，要用一般现在时。
