从句之名词从句
让我们想一想名词在句子中能做哪些成分呢？
The boy is ud to getting up early. He left his wallet at home this morning.
She is my best friend. He, the headmaster, is responsible for the daily routine of the school.
从以上句子中，名词的成分，我们可以总结出，名词从句分为_____________ 、___________
_______________、_______________.
名词从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。
主语从句: eg. What you said is quite uful for us to improve our English ability.
What surprid me most was that the little girl could play the violin so well.
How he was successful is still a puzzle.
从以上三个句子分析，主语从句的语序是_________________.
连词的选用：
（1）that和what的选用
What he wants is a book. What excited him was that he got the first prize.
That light travels in straight lines is known to all. 众所周知，光线沿直线运行。
That Sichuan is famous for pandas is well-known to Chine people.
that和what都可引导主语从句。what初中英语教学反思除起连接作用外，还在名词性从句中充当某些成分，可作从句的主语、宾语或表语。而that在名词性从句中不充当任何成分，无词义，只起连接词作用。
（2）if和whether（是否）的选用
引导主语从句，不能用if，只能用whether。如：
Whether we will hold a party in the open air tomorrow depends on the weather.
Whether he will be on a business trip is not decided.
练一练：
① ________ you don't like him is none of my business.
大脑镰下疝 A. What B. Who C. That D. Whether
② After Yang Liwei succeeded in circling the earth, ________ our astronauts desire to do is to walk in space. A. where B. what C. that D. how
（3）其它连接代词和副词的选用
When we shall hold our sports meet is not decided. Who broke the glass yesterday is not clear.
Which car you will choo to buy makes no difference.
Where we shall hold the party depends on the number of people to come.
Why he went to Qing Chengshan for a holiday was that it was cool there in summer.
How he will spend his spare time depends on his feelings.
How they will solve the rious problem has not been decided
Where we can look up his address is still a problem.
Why he did that wasn't quite clear. How much water is flowing can be easily measured.
根据主语从句的具体意义，正确的选择who, which, when, where, why, how等连接词，这些连接词既有疑问含义，又起连接作用，同时在从句中充当各种成分。
（4）whatever / whoever/ whoever/whichever 等的使用
whatever, whoever在主语从句中不含疑问意义。它引导主语从句，并在从句中作主语、宾语、表语等。whatever = anything that; whoever = anyone who。要注意和whatever, whoever引导的让步状语从句的区别。如：
Whoever breaks the law should be punished.＝ Anyone who breaks the law should be punished.
感恩社会Whatever you do will make a difference to your future.= Anything that you do will make a difference to your future.
Whoever is elected as monitor is all right.= Anyone who is elected as monitor is all right.

Whoever leaves the room last ought to turn off the lights.
it构成的主语从句
（1）That the college will take in more new students this year is true.
It is well-known that the earth moves around the sun.
改为that 引导的主语从句：
由连词that引导的主语从句，在大多数情况下会放到句子的后面，而用代词it作形式主语。
（2）常见用it作形式主语的复合句结构
