It 用作形式賓語(yǔ) 當(dāng)不定式(短語(yǔ))锄码、動(dòng)名詞(短語(yǔ))或從句在某個(gè)句子中作賓語(yǔ)時(shí)夺英,為保持句子結(jié)構(gòu)平衡,避免句式結(jié)構(gòu)的混亂滋捶,常用it作形式賓語(yǔ)痛悯,而將真正的賓語(yǔ)放在句尾。此時(shí)it仍只起先行引導(dǎo)作用重窟,本身無(wú)詞義载萌。
其基本結(jié)構(gòu)為“動(dòng)詞+it+賓語(yǔ)補(bǔ)足語(yǔ)+不定式(動(dòng)名詞或從句)”。
① 當(dāng)不定式(短語(yǔ))巡扇、動(dòng)名詞(短語(yǔ))或從句在復(fù)合賓語(yǔ)結(jié)構(gòu)中作某些動(dòng)詞的賓語(yǔ)時(shí)(如think, make, find, consider, feel, suppose等)扭仁;
基本句式結(jié)構(gòu)—— 一、動(dòng)詞+ it + that-從句霎迫。
如: (1)sb find/ believe/ think/ feel/ consider/ make + it +n+to do/that從句
I take it (that) he will come on time. 我認(rèn)為他會(huì)準(zhǔn)時(shí)來(lái)的。
He makes it a rule never to borrow money.(他立志決不向別人借錢(qián)帘靡。)
I think it no need talking about it with them.(我認(rèn)為沒(méi)必要跟他們談知给。)
(2)sb find/think/make + it + adj. + to do sth/that 從句(賓語(yǔ)從句)
如: I don’t feel it difficult to understand the Special English.(我覺(jué)得理解英語(yǔ)特別節(jié)目并不難。)
I find it interesting to learn English.
二描姚、動(dòng)詞 + prep + it + that-從句涩赢。
如: I can’t answer for it that he will come. 我不能保證他會(huì)來(lái)。
You may rely on it that he’ll come to meet you. 你放心轩勘,他會(huì)來(lái)接你的筒扒。
You may depend on it that we shall always help you.(盡管放心,我們會(huì)隨時(shí)幫你的绊寻。)
說(shuō)明:能用于此結(jié)構(gòu)的動(dòng)詞不多花墩,常見(jiàn)的有see to, look to, insist on, stick to, depend on, answer for 等。 注意: that引導(dǎo)的賓語(yǔ)從句不能直接作介詞的賓語(yǔ)
?三澄步、動(dòng)詞 + it + 介詞短語(yǔ)+ that-從句冰蘑。
如: We owe it to you that there wasn’t a serious accident.(多虧了你才沒(méi)有發(fā)生嚴(yán)重事故。)
I took it for granted that he would help us. 我認(rèn)為他會(huì)幫助我們的村缸。
注意:由及物動(dòng)詞與介詞組成的固定搭配中祠肥,賓語(yǔ)從句若作該動(dòng)詞的賓語(yǔ)時(shí),須借用it梯皿。常見(jiàn)的有take it for granted, bring it to sb’s attention, owe it to sb 等仇箱。
四、動(dòng)詞 + it + when /if/that-從句东羹。
如: (1)sb+hate / dislike / love / like+it+when-從句
I hate it when my mother asks me to eat eggs.(我討厭母親要我吃雞蛋剂桥。)
?I dislike it when you whistle. 我不愛(ài)聽(tīng)你吹口哨。
(2)sb+appreciate/prefer+it+if-從句
I really appreciate it if you could help me with my math. I’d prefer it if I didn’t have to do so much work. 要是我不必做那么多工作属提,好就太好了渊额。
說(shuō)明:能用于此結(jié)構(gòu)的動(dòng)詞不多,常見(jiàn)某些表示“喜、怒旬迹、哀火惊、樂(lè)”的動(dòng)詞,如 enjoy, hate, love, like, dislike, appreciate, prefer 等奔垦。往往不能直接接賓語(yǔ)從句
