Step2 Cnclusin
概念：复合句中用作主语的名词性从句叫作主语从句。
形式：
连词that
连词whether
连接代词wh、what、which
连接副词when、where、hw、why等
Step3 Study
连词that在引导名词性从句时本身没有意义，在从句中不担任任何句子成分，但引导主语从句时不能省略。
e.g. 1）That yu didn't knw the rules wn't be an excuse fr yur failure.
2）That the earth is rund is a fact.
3）As I searched the name Linda n the Internet，it became evident that there're tw with the same name wh lk cmpletely different.
2. 考点总结
1）that引导主语从句位于句首时，本身无意义，但是不可省略。
2）that从句作主语时，常用it作形式主语，常见句型有：
①It＋be＋形容词(bvius，natural，surprising，etc.)＋that从句
②It＋be＋名词词组(n wnder，an hnr，a pity，etc.)＋that从句
③It＋ be＋过去分词(said，reprted，thught，etc.)＋that从句
e.g. It is annunced in tday's newspaper that Xi Jinping will pay a visit t Russia next week
2）whether(注意不能用if)在主语从句中表示的意思为：是否。
e.g. 1）Whether she will win the prize is still unknwn.
2）Whether he will cme is nt decided.
3）It remains t be seen whether the newly frmed cmmittee's plicy can be put int practice.
3）连接代词what（什么）, wh（谁）, which（哪一个）,—ever（无论）在从句作主、宾、表语等。
e.g. 1）Whever is the last t leave shuld turn ff the lights.
2）What sme scientists have fund is that their lng-term use can smetimes harm bth the land and peple's health.
3）Whever wants t stay in a htel has t pay their wn way.
考点总结
1．what引导名词性从句时，意为“什么”或“……的”，在从句中用来作主语、宾语、表语或定语。
2．wh－ever引导名词性从句时，其作用等同于其前面的连接词，意为“任何……”或“无论……”，含有强调的语气。
e.g. 1）What wrries us mst is wh let ut the secret.
2）Whever breaks the law shuld be punished.
4）连接副词when、hw、where、why，在主语从句中，表示的意思分别为：何时、怎样、何地、为什么。
e.g. 1）Hw this culd be dne was a gd questin.
2）Why she didn't shw up remains a puzzle.
3）Where Li Bai，a great Chinese pet，was brn is knwn t the public，but sme wn't accept it.
5. It作形式主语
为保持句子平衡，常把主语从句后置，而用形式主语it代替，it作形式
主语时常用于以下句型：
①It＋be＋形容词(bvius，natural，surprising，etc.)＋that从句
②It＋be＋名词词组(n wnder，an hnr，a pity，etc.)＋that从句
③It＋ be＋过去分词(said，reprted，thught，etc.)＋that从句
在“It + 系动词 + 形容词 + 主语从句”句型中,如果形容词为necessary，imprtant,strange,
natural等时,从句谓语动词常用“(shuld)+动词原形”。
在“It + 系动词 + 过去分词 + 主语从句”句型中,如果过去分词为suggest,advise,request
,require等时,从句谓语动词使用“(shuld)+动词原形”。
6.主语从句注意事项
1．从句要用陈述语序
Hw the accident happened was still a puzzle.
2．注意主谓一致
(1)从句作主语时，主句的谓语一般用单数形式。
Whether he will g hme r nt after graduatin has puzzled him much.
(2)如果由and连接两个或两个以上的主语从句作主语时，谓语动词用复数；
由两个或多个连接词引导一个主语从句时，谓语动词用单数。
When and where they will hld the meeting is nt clear.
When they will start and where they will g have nt been decided yet.
7.主语从句连接词使用的判断方法：
Step1（从第二个动词前）划出主语从句
Step2 找出从句的谓语动词（观察其前后是否少主宾等成分）
Step3 连词考虑顺序：
连接代词——连接副词——whether——that
e.g. this culd be dne was a gd questin.
Hw this culd be dne was a gd questin.
