1. 名词性从句的本质

重点：用三种句子充当四种成分

⑴ 宾语从句

例句：

② I do not know whether he will cry.

③ I do not know why he cries.

⑵ 主语从句

例句：

①That the earth is round has been known for years.

③ My question is when people will live on the moon.

⑷ 同位语从句

① 同位语定义：

当两个指同一人或物的名词放在一起，后者在解释前者时，后者就是前者的同位语。

ⅰ My best friend, Henry, lives in Australia.

ⅱ His fish, Tom and Jerry, need to be fed once every day.

ⅲ My childhood home, a yellow house, is just down the road.

思维导图：用三种句子充当四种成分

2.名词性从句中连词的特点

⑴ 四种名词性从句中连词的特点

当从句是陈述句时that （无实际含义）

当从句是一般疑问句时whether if （有实际含义）

当从句是特殊疑问句时when,where,why how,who,what,which,whose等（有实际含义）

⑵ 小结

① 除了that之外，都有实际含义。

② 这类连词较为规律：

从句是陈述句时，用that 引导

是一般疑问句时，用whether

是特殊疑问句时，用特殊疑问词引导

3.如何迅速判断出各种名词性从句

根据连词的位置，我们给大家整理出了一个大概的思考方向

⑴ 当连词放在介词和动词之后，常引导宾语从句

⑵ 连词放在句首（除when以外），常引导主语从句

⑶ 连词放在be动词之后，常引导表语从句

⑷ 连词只有放在“包含信息的名词” 如

（argument,belief,conclusion,fact,idea,newsopinion,problem,question,theory,view...）之后，才可能引导同位语从句

举例：

①This means that they may grow up without consideration for others.

②University graduates usually face the dilemma of whether theyshould get a job or continue their education.

③What you are doing seems very good.

④When lazy students whine, the teacher will throw chalks at their heads.

⑤When she will come is hard to say.

⑥Home is where I want to be.

⑦

ⅰ Young people are filled with the belief that anything is possible.

ⅱ We have reached the conclusion that the schools need more support.

ⅲ The air that our kids breathe is polluted.
