Subject clauses
1 Look at the sentences and answer the questions. Sentences (a) and (c) are from the reading passage.

b “ That my pictures aren't hurting anyone is what I say, so who cares ”
c It's true that inner beauty is very important...
d That inner beauty is very important is true...
1 What is the role of the words in red in each sentence

b “ That my pictures aren't hurting anyone is what I say, so who cares ”
c It's true that inner beauty is very important...
d That inner beauty is very important is true...
2 In sentence (a), what does “what” refer to

4 Why does the author choose to use sentences (a) and (c) instead of sentences (b) and (d)
The author chooses to use sentences (a) and (c) to place the focus on the end of the sentences, rather than the beginning.
a … what I say is that my pictures aren't hurting anyone, so who cares
b “ That my pictures aren't hurting anyone is what I say, so who cares ”
c It's true that inner beauty is very important...
d That inner beauty is very important is true...
Now look for more sentences with subject clauses in the reading passage, and summarise their uses in your own words.
I mean, isn't it better that I'm large and happy, instead of skinny and unhealthy
What I really admire is the way she has acknowledged that good health not only makes us more beautiful, but happier, too!
主语从句
一、主语从句概述
主语从句即在主从复合句中用作主语的从句。主语从句通常由连词that, whether/if,连接代词(what, which, who等)或连接副词(when, where, why, how等)引导。
What caused the accident is a complete mystery.
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 still unknown.
哪个队会赢得这场比赛还不知道。
二、从属连词that, whether/if引导的主语从句
连接词that本身没有意义,不作句子成分, that不能略;whether/if尽管不充当句子成分,但是含有“是否”的意思,可以加上“or not”,其语意不变。若主语从句位于句首或和or not 连用时,则必须用连接词whether,而不用 if。
That they will go is certain.
他们去是肯定的。
Whether she’s coming or not doesn’t matter too much.
她来不来没有多大关系。
三、it作形式主语引导主语从句
如果主语从句太长,为避免句子结构头重脚轻,我们可用it作形式主语。that引导的主语从句可用it代替,that 不可省略。that引导主语从句时,常用it作形式主语,常见句型有:
(1) It +be+形容词(necessary/ right/likely/ unlikely/ wrong/ important/certain等)+that从句.
It is wonderful that all of you have passed the difficult exam!
你们都通过了这次很难的考试真令人高兴!
(2) It+ be+名词(短语)(a pity/a shame/a surprise/no wonder等)+that从句.
It is a pity that you have missed the wonderful lecture.
你错过了这么精彩的演讲真遗憾。
(3) It+ be+过去分词(said /told/ reported/ decided/ suggested等)+that从句.
It is suggested that the lab building (should) be built next year.
有人建议实验楼明年修建。
(4) It+特殊动词(seems/appears/happens/matters)+that从句.
It appears that they have made the same mistake.
好像他们犯了同样的错误。
【温馨提示1】
在以下主语从句中,常使用虚拟语气,即“should+动词原形”形式,其中的should可以省略。
①It is necessary/strange/important/natural...+that...
②It is a pity that...
③It is suggested /requested /required/ proposed/ desired ...+that...
【温馨提示2】
whether引导的主语从句既可放在句首也可放在句末,但if引导的主语从句只能放在句末,且前面需用it作形式主语。
Whether it is true remains a question.
这是否是真的依然是个问题。
It is unknown if he will attend the meeting.
他是否会参加会议还不清楚。
四、由连接代词引导的主语从句
(1)关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导主语从句时,它们分别在从句中担任主语、宾语或定语(whose),不能省略。
Whoever leaves the room last ought to turn off the lights.
走得最晚的应当关灯。
What you have done might do harm to other people.
你的行为可能伤害别人。
(2) what引导主语从句表示“……的东西/事情”时,等同于the thing(s)which/that。what, who, whom, which,可以和ever构成合成词引导从句,ever 起强调作用。这些关系词在句子中充当成分,所以不能省略。此类主语从句不能用形式主语it引导。
What I need (=The thing which/that I need) is a mobile phone.
我所需要的是一部移动电话。
Whoever leaves the office should tell me.
无论是谁离开办公室都应该告诉我。
五、连接副词引导的主语从句
连接副词when, where, why, how, however, whenever, wherever等引导主语从句时,它们在从句中担任状语,不能省略。
How a telephone works is a question which not everyone can answer.
电话是怎样工作的,这个问题并不是每个人都能回答。
六、主语从句不可位于句首的四种情况
(1) 含主语从句的复合句是疑问句、感叹句时,主语从句不可提前,用引导词it作形式主语。
Is it really true that he has gone abroad
他真的出国了吗
(2) It is said/reported...结构中的主语从句不可提前。
It’s said that the play is very interesting.
据说这部戏剧很有趣。
(3) It happens/occurs...结构中的主语从句不可提前。
It occurs to her that she has forgotten to lock the door.
她突然想起忘了锁门。
(4) It doesn’t matter how/whether or not...结构中的主语从句不可提前。
It doesn’t matter how he will come.
他怎么来不重要。
it作形式主语和it引导强调句的比较
it作形式主语代替主语从句, 主要是为了平衡句子结构, 主语从句的连接词有变化。
it引导的强调句则是对句子某一部分进行强调, 无论强调的是什么成分, 都可用连词that。被强调部分指人时也可who/whom。
e.g. It is a pity that you didn’t go to see the film.
It doesn’t interest me whether you succeed or not.
It is in the morning that the murder took place.
It is John that broke the window.

Read the passage and choose the correct words.
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.
that
what
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!

Write an introduction to Ma Xu based on the profile. Use three or four subject clauses in your introduction.
Ma Xu became a military doctor in 1947. She applied to become a paratrooper in 1961, but her first application failed because there were no female paratroopers at that time. Ma was only 1.53 metres tall and weighed just 37.5 kg. But she learnt to parachute by training hard in secret. After Ma proved that she could jump as well as anyone else, her application was successful.
Ma is China’s first female paratrooper. She completed over 140 parachute jumps over a period of 20 years – the most of any female paratrooper. She also set a national record as the oldest enlisted woman to do a parachute jump, at the age of 51.
In 2018, Ma donated her entire life savings to her home town in Mulan County. This donation was to support local education and public welfare.
Ma Xu is a famous paratrooper. What impress me most are her courage, skill and determination…
