主语从句
My brother makes me happy
弟弟使我高兴
我弟弟上学了使我高兴
That my brother went to school makes me happy.
含义:充当主语的从句叫做主语从句
What he did in the earthquake moved everybody.
Why we choose to study here is clear to all of us.
Whether she will come or not is still a question.
How we can get there in time will be our focus.
一、引导主语从句常用的连接词:
(1)从属连词:that、if、whether
① that 在从句中不充当句子成分,也没有实际意义,只起连接作用,但不可省略。
That smoking is harmful to health is known to everyone.
吸烟有害健康,这是大家都知道的。
② whether 在从句中不充当句子成分,只起连接作用,意为“是否”。
whether 引导的主语从句既可放在句首,也可放在句末。而 if 引导的主语从句不能放在句首,只能放在句末。
Whether life exists on other planets is not clear yet. 其他星球上是否存在生命还不清楚。
It is still doubtful whether/if she will play the role. 她是否要演这个角色还很难说。
(2)连接代词:who,whom,whose,what,which,whoever,whatever,whichever 等
连接代词在从句中作主语、宾语、表语或定语,起连接作用并且有实际意义。
(3)连接副词:when, where, why, how
在从句中作状语分别表示时间、地点、原因和方式,起连接作用并且有实际意义。

二、 用 it 作形式主语的主语从句
当主语从句太长时,为了平衡句子结构,常用it作形式主语,而把主语从句后置。用it作形式主语的常见句型有:
(1)It+is+ 形容词 +that 从句.
·It is true/ clear/ well-known/ obvious/(im)possible/ right +that...
It is clear that the girl told a lie. 很清楚那个女孩说谎了。
It is possible that Mira might turn up tonight. 米拉今晚可能会来。
(2)It+is+ 名词(词组)+that 从句.
·It is a pity/ a shame/ a wonder/ a question/ no wonder +that...
It is a pity that your parents didn’t permit you to go with us.
你父母不允许你和我们一起去,真遗憾。
It’s a wonder that no one got hurt.
竟然没有人受伤,真是奇迹。
(3)It+is+ 过去分词 +that 从句.
·It is said/ reported/ believed/ expected/ thought/ hoped/ suggested+that+从句
It is reported that a violent earthquake happened in Japan.
据报道,日本发生了强烈地震。
【误区警示】
当过去分词是suggested,ordered,required,advised,requested,insisted等表示建议、要求、命令等的词时,主语从句应使用虚拟语气,即谓语动词用“(should +)动词原形”。
It is suggested that the work(should)be done with great care.
有人建议,这项工作得特别谨慎地去做。
(4)It + 不及物动词(短语)+ that 从句.
常用于该句型的不及物动词(短语)有seem(看上去),turn out(结果是),happen(碰巧),appear(显得)等。
It turned out that we were wrong. 结果是我们错了。
It happened that he was out that day. 碰巧他那天不在家。
(5)其他句型
It doesn’t matter whether he likes it or not. 他喜不喜欢它都没有关系。
It makes no difference whether you support my plan or not. 你支不支持我的计划都不重要。
完成句子
(1) _______________________(很明显)they badly need help.
(2)_________________________(是否……没有关系)you come to the party or not tonight.
(3)____________________(很可惜)you can’t attend my birthday party.
(4)____________________(建议) the old man should go to the countryside to have a rest.
(5)____________________(在我看来)you disagree on the plan.
(6)____________________(碰巧)the harvest was bad that year.
(7)____________________(结果是)she was a friend of my sister.
It’s clear/obvious that 
It doesn’t matter whether
It’s a pity that 
It’s suggested that
It seems to me that
It happened that
It turned out that

(2)It+is+ 名词(词组)+that 从句.
(3)It+is+ 过去分词 +that 从句.

It makes no difference whether... 是否...没有区别
It is a well-known fact that/what the faces some people show to the world might be completely different to their real personalities. For instance,most comedians have permanent smiles on their faces and always sound cheerful because that’s the nature of their work. From this,it’s impossible to know what/where their true feelings are. Although they might be laughing on the outside ,they might be crying on the inside. That/How others are feeling is not something that we should make assumptions about,because it’s not always obvious who is truly happy. What/That is certain is that comedians often use comedy to help them understand themselves and the world. In fact,comedy is a very serious job indeed!
