1)由從屬連詞that引導(dǎo)的從句叫做名詞性that-從句。 That只起連接主句和從句的作用，在從句中不擔(dān)任任何成分，本身也沒有詞義。名詞性that-從句在句中能充當(dāng)主 語(yǔ)、賓語(yǔ)、表語(yǔ)、同位語(yǔ)和形容詞賓語(yǔ)，例如：
主語(yǔ)：That he is still alive is sheer luck. 他還活著全靠運(yùn)氣。
賓語(yǔ)：John said that he was leaving for London on Wednesday. 約翰說他星期三要到倫敦去。
表語(yǔ)：The fact is that he has not been seen recently. 事實(shí)是近來(lái)誰(shuí)也沒有見過他。
同位語(yǔ)：The fact that he has not been seen recently disturbs everyone in his office.
近來(lái)誰(shuí)也沒有見過他，這一事實(shí)令辦公室所有的人不安。
形容詞賓語(yǔ)：I am glad that you are satisfied with your job.
你對(duì)工作滿意我感到很高興。
2)That-從句作主語(yǔ)通常用it作先行詞，而將that-從句置于句末，例如：
It is quite clear that the whole project is doomed to failure. 很清楚，整個(gè)計(jì)劃注定要失敗。
It’s a pity that you should have to leave. 你非走不可真是件憾事。
用it作形式主語(yǔ)的that-從句有以下四種不同的搭配關(guān)系：
a. It + be +形容詞+ that-從句.
It is necessary that… 有必要…….
It is important that… 重要的是…….
It is obvious that… 很明顯…….
b. It + be + -ed 分詞+ that-從句.
It is believed that… 人們相信…….
It is known to all that… 從所周知…….
It has been decided that… 已決定…….
c. It + be +名詞+ that-從句.
It is common knowledge that… ……是常識(shí).
It is a surprise that… 令人驚奇的是…….
It is a fact that… 事實(shí)是…….
d. It +不及物動(dòng)詞+ that-分句.
It appears that…似乎…….
It happens that…碰巧…….
It occurred to me that… 我突然想起…….
17.3 名詞性wh-從句.
1)由wh-詞引導(dǎo)的名詞從句叫做名詞性wh-從句。Wh-詞包括who, whom,. whose, whoever, what, whatever, which, whichever等連接代詞和where, when, how, why等連接副詞。Wh-從句的語(yǔ)法功能除了和that-從句一樣外，還可充當(dāng)介詞賓語(yǔ)、賓語(yǔ)補(bǔ)語(yǔ)和間接賓語(yǔ)等，例如：
主語(yǔ)： How the book will sell depends on its author. 書銷售如何取決于作者本人。

間接賓語(yǔ)：The club will give whoever wins a prize.
