小學(xué)英語(yǔ)語(yǔ)法知識(shí)點(diǎn):名詞性that-從句

  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(méi)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(shuō)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(méi)有見(jiàn)過(guò)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(méi)有見(jiàn)過(guò)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……
