主語(yǔ)從句
whoever“無(wú)論誰(shuí)”,可以引導(dǎo)主語(yǔ)從句
它即是breaks the law的主格 又是be punished的主語(yǔ)
主語(yǔ)從句有以下幾種類(lèi)型
1.常規(guī)主語(yǔ)從句,即句子在復(fù)合句中充當(dāng)一個(gè)主語(yǔ),比如
（1）That he finished writing the composition in such a short time surprised us all.
（2）Whether we will go for an outing tomorrow remains unknown.
（3）Who will be our monitor has't been decided yet.
2.為了防止句子頭重腳輕,通常把形式主語(yǔ)it放在主語(yǔ)位置,真正主語(yǔ)擱置于句末,比如
（1）It is certain that he will win the match.
（2）It is true that he has made a very important discovery in chemistry.
（3）It is very likely that they will hold a meeting.
這個(gè)句子屬于第一類(lèi)型
關(guān)于主從還有以下幾點(diǎn)總結(jié):
引導(dǎo)主語(yǔ)從句連詞有that,whether,who,what,whatever等
連詞位于句首不能省略
主語(yǔ)從句大多數(shù)情況下視為單三,但也有例外
以that 引出的主語(yǔ)從句,常以形式主語(yǔ)it引導(dǎo).
It is +形容詞/名詞/某些動(dòng)詞ed + that 從句.
在有些that從句中要用虛擬語(yǔ)氣
