一、主语从句的概念与类型
主语从句在复合句中作主句的主语,引导主语从句的词有从属连词that, whether以及连接代词who, what,which, whoever, whatever, whichever和连接副词when, where, why, how等.
例如:
That she was chosen made us very happy.
她当选了使我们很高兴.
What caused the accident is a completemystery.
是什么导致了这次事故还完全是一个谜.
Whether she will come or not is still a question.
她是否来还是一个问题.
Which team will win the match is stillunknown.
哪个队会赢得这场比赛还不知道.
Whoever comes to the party will receive apresent.
参加聚会的每一个人都将收到一份礼物.
When they will start has not been decidedyet.
他们何时出发还没决定.
注意:上述例句中的主语从句都是放在句首,但有时为了使句子结构平衡,避免\"头重脚轻\",常用it作形式主语,而把从句放在后面.
例如:
It is a pity that she has made such amistake.
她犯了这样一个错误,真是遗憾.
It depends on the climate whether they aregoing shopping today.
他们是否今天去购物还得看天气情况.
这样就构成了下面一些常用句型:
1)It is + adj. / n. +从句
It is a pity/shame that...遗憾的是……
It is possible that...很可能……
It is unlikely that...不可能……
2)It +不及物动词+从句
It seems/appears that...似乎……
It happened that...碰巧……
3)It + be +过去分词+从句
It is said that...据说……
It is known to all that...众所周知……
It is reported that...据报道……
It is believed that...据信……;人们相信……
It is suggested that...有人建议……
It must be pointed out that...必须指出……
It has been proved that...已证明…….
例如:
It is believed that at least a score ofbuildings were damaged or destroyed.
据信,至少有二十座楼房遭到破坏或彻底毁掉.
It is suggested that the meeting should beput off.
有人建议会议延期召开.
It\'s reported that three people were killedin the accident and five were hurt badly.
据报道,事故中三人丧生,五人重伤.

二、学习主语从句应该注意的几个问题
1)引导词that与what
what既有引导主语从句的作用,同时又在从句中作句子成分(主语、宾语、表语等).这时what相当于all that/everything that...,常译成\"所……的(东西、事情、话等.)\";而that只起连接作用,本身无实际意义,在从句中也不担当任何句子成分.但that引导的主语从句放在句首时,不能省略that.
例如:
What is done can\'t be undone.
(谚语)已成定局,无可挽回.
What we can\'t get seems better than what wehave.
我们得不到的东西似乎比已得到的要好. That we should work out a plan to deal with the present serioussituation is important.
我们应该制定一项计划来应付目前严峻的形势,这一点非常重要.
That a new teacher will come to teach usgeography is true.
一位新老师将来教我们地理,这是真的.
