17.2 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…… |
