1）.引导主语从句的连接词有：

连词that,whether；连接代词who,whoever,what,whatever和which；连接副词when,where,how和why。

注意：

1.that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。

2.表示“是否”时,只能用“whether”引导主语从句

3.疑问词（when,where,why,what…）+陈述语序

2）.为了防止一些句子头重脚轻，通常用it做形式主语

2.Itissurprising_______theweatherissowarmforApril.

A.thatB.whenC.whetherD.where

3.Thattheearthisroundistrue.=

4.Whetherhewillcomehasn’tbeendecided.=

5.Wheretheherowentisnotmentionedattheendofthestory.=

用it做形式主语的常用句型

Itisafact（ashame,apity,goodnews…）

Itistrue（certain,clear…）

Itissaid（reported,believed…）

Itseems/happenedthat…

Itworriedsbalotthat…

注意：

Itisimportant/natural/necessary/impossible/strange/unusual/suggested/advised/ordered/requested/insisted/required…that中，从句谓语动词用“（should）+do”的形式,

Itisnecessarythatwe________________（learn）Englishgrammarwell.

Itissuggestedthatwe________________（notgo）outtoplay.

3）.Who,whom,which,what可以和ever构成合成词，引导从句，起加强语气的作用。

但引导主语从句不能用nomatterwho/what…
