3、?含义：含义：在句子中起名词作用的各种从句统称为名词性从句。根据它们在句中的语法作用，又可分为主语从句、宾语从句、表语从句和同位语从句。复合句中用作主语的从句叫主语从句。引导词：引导词：连接词：that,whether,if连接代词：what,which,who,whom,whose,whatever,whichever,whoever,whomever连接副词：when,where,why,how1.that在主语从句中不充当句子成分，也没有含义，只起连接作用，但通常不能省略。That you will have an answer is certain.你能得到答复，这是肯定的。2.tha

4、t引导的从句作主语时，为避免头重脚轻，使句子平衡，常用it作形式主语，而将that引导的主语从句后置，that不能省略。常用it作形式主语代替that从句的句型有以下几种：（1）It+be+形容词（obvious,true,natural,likely,possible,certain,etc.）+that从句。It is obvious that youve made a big mistake.显然，你犯了一个大错。注意：在“It is necessary/important/strange/natural+that从句”中，从句常用虚拟语气，即从句谓语用should+动词原形的形式，sh

7、no passengers were injured in the accident.据报道，这起事故中没有乘客受伤。注意：当过去分词是 suggested,advised,ordered,requested,required等表示建议、要求、命令等的词语时，从句要用虚拟语气，即“从句的谓语用should+动词原形”的形式，should 可以省略。It is suggested that the meeting(should)be put off.有人建议会议延期举行。（4）其他It doesnt matter that.是无关紧要的。It struck/hit sb.that.某人突然想到I

8、t appears/seems/happens that.似乎/碰巧It struck me that nobody was in favour of the change.我突然想到没有人赞成这种改变。It happened that I wasnt there that day.碰巧那天我不在那里。whether/if在从句中不充当句子成分，仅起连接作用，意为whether/if 引导的主语从句“是否”。whether引导的主语从句可置于句首，也可置于句末；而if引导的主语从句不能置于句首，只能置于句末。Whether the meeting will be held on time is

9、 still a question because of the hurricane.由于飓风的影响，这次会议是否会如期举行还是个问题。It is still under discussion whether/if the old bus station should be replaced with a modern hotel.是否该把这个旧的公共汽车站换成一家现代化的旅馆仍在讨论中。连接代词 who,what,which,whoever,whatever,whichever等引导主语从句时，既起连接作用，同时在从句中又充当主语、宾语或表语等成分。Who broke the glass y

12、并列从句作主语。When they will set off for London and where they will stay have not been decided yet.他们将于何时出发去伦敦以及要住在哪里还没定下来。（3）what从句作主语时，根据意义一致原则决定主句谓语的数。若表示复数意义，则主句谓语用复数What he says and does do not agree.他言行不一致。若表示单数意义，则主句谓语用单数What he says and does does not concern me.他的言行与我无关。1._ hit me that I had to at
