一、概念在句中充当主语的从句称为主语从句。英语中带有主语从句的句型可分为两大类：一是直接将主语从句放在主语的位置上；二是用it作形式主语，将真正的主语从句后移，放在其他成分之后。从句作主语时，谓语动词一般用单数形式(what从句作主语时，如果含有复数概念时，谓语动词可用复数形式)。That mathematics is the base of other science is known to all of us.It is known to all of us that mathematics is the base of other science.众所周知数学是其他科学的基础。
语法精析
二、类型1.that，whether引导的主语从句：连词只起连接作用，在从句中不充当句子成分，可用it作形式主语代替。That he won the game made a tremendous stir in our country.他赢得比赛一事在我国引起了巨大轰动。Whether it will do us harm or good remains to be seen.此事对我们有害还是有利还有待于看一看。It depends on how hard he works whether one can succeed.一个人能否成功取决于他工作努力的程度。
[温馨提示]if有时也可引导主语从句，但只能用it作形式主语，if从句后置。It is doubtful if they will come.他们是否会来值得怀疑。
2.连接代词what(ever)，which(ever)，who(ever)，whom(ever)，whose引导的主语从句：这类连词除起连接作用外，还在从句中充当一定的句子成分，可作主语、宾语、表语或定语。What she did after that is not clear to us.那之后她做了什么我们不清楚。Whatever is worth doing at all is worth doing well.凡是值得做的事都值得好好地做。
Which of all those ways is the best is uncertain.所有那些方法中哪一个最好还不能肯定。Whom we must serve is a question of vital importance.我们应当为谁服务是一个极为重要的问题。Whose carelessness spoilt the work must be made clear.必须查清是谁的粗心破坏了工作。It is still open to question who is to head the group.谁领导这个小组还未决定。
3.连接副词when，where，how，why引导的主语从句：这类连词在从句中常作状语，也可用it作形式主语代替。When and where the meeting will take place has not been decided yet.开会的时间和地点还未决定。Why he did it will remain a puzzle forever.他做此事的原因将永远是个谜。It is not clear how accurate the results are.这些结果的精确程度还不清楚。
三、it作形式主语的主语从句1.It is/was＋形容词＋主语从句It is quite clear that the crime has been done deliberately.十分明显这是故意犯罪。It was clear enough what she meant.她的意思已经够清楚了。It is uncertain why he denied the charge.不确定他为什么否认了指控。
2.It is/was ＋名词＋主语从句 It is a good thing that we do morning exercises every day.我们每天做早操是件有益的事。It is a complete mystery what caused the accident.是什么引起了这场事故完全是个谜。It’s not my business how she chooses to live.她选择什么样的生活不关我的事。3.It is/was＋过去分词＋主语从句 It is required that the machine should be maintained at regular intervals.机器需要定期维修。
It is not yet known whether they will send a delegation to the conference，but we hope they will.还不了解他们是否会派代表团来参加会议，但是我们希望他们派团来。Has it been decided where we are to hold the meeting?决定了我们开会的地点了吗？4.It＋不及物动词＋主语从句It happened that I wasn’t there that day.碰巧那天我不在那里。It doesn’t matter what she looks like.她的外表怎么样并不重要。
5.It is/was＋介词短语＋主语从句It is of great importance whether we can improve our scientific research or not.我们能否提高我们的科学研究是极为重要的。[温馨提示]在It is important/necessary/natural/essential/impossible...＋that从句和It is demanded/suggested/required/requested/proposed...＋that从句中，从句的谓语动词用虚拟语气，即(should) do形式。It is necessary that a scientific worker (should) know foreign languages.科学工作者必须精通外语。It is desired that remote control (should) be introduced in this system.有人想要把遥控装置引进该系统。
四、主语从句中应注意的问题1.从句要用陈述语序What we will do next should be decided.应该决定一下我们下一步该做什么。2.主谓一致(1)从句作主语时，主句的谓语一般用单数形式。Where he will get a job after graduation has puzzled him much.毕业后到哪儿找份工作使他很困惑。
[温馨提示]what引导主语从句时，有时主句的谓语动词应与主句中作表语的名词保持一致。What the school needs most are books.这所学校最需要的是书。
(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 they will start and where they will go have not been decided yet.他们将在什么时候动身以及要去哪里还没定下来。When and where the movie will be shown is not clear.这部影片何时何地上映还不清楚。
