1、it 用作形式賓語的四個(gè)特殊句式當(dāng)不定式、動名詞、從句等復(fù)雜成分用作賓語且其后跟有賓語補(bǔ)足語時(shí)，通常會 在賓語補(bǔ)足語前使用形式賓語 it ，而將真正的賓語移至句末， 此時(shí) it 仍只起先行引導(dǎo)作用， 本身無詞義。其基本結(jié)構(gòu)為 動詞+it+賓語補(bǔ)足語+ 不定式（動名詞或從句）”。女口： I find it difficult to do the job well. 我發(fā)現(xiàn)做好這件事不容易。I think it best that you should stay here. 我認(rèn)為你最好住這兒。We think it no use complaining. 我們認(rèn)為抱怨是沒有用的。I don &#

2、39; t feel it difficult to understand the Special English（. 我覺得理解英語特別節(jié)目并不難。）He makes it a rule never to borrow money. （他立志決不向別人借錢。 ）I think it no need talking about it with them. （我認(rèn)為沒必要跟他們談。 ）We think it our duty to clean our classroom every day.He felt it important to learn English well.They found

3、 it difficult that they would finish their work in two days.能這樣用的動詞有： think, make, find, consider, feel, suppose 等。為了記憶方便我們可稱該句 型為 "6123 結(jié)構(gòu) " 。6 指主句中常用的動詞： think, believe, make, find, consider, feel ；1 指的是形式賓語 it；2 指的是賓補(bǔ)的兩種形式：形容詞或名詞；3 指的是真正賓語的三種形式：不定式短語，動名詞短語或that 引導(dǎo)的賓語從句。但是，以下幾種用 it 作形式賓語

4、的句型比較特殊，同學(xué)們需引起注意（同時(shí)它們也是高考 的常考考點(diǎn)） ：1. 動詞 + it + that- 從句。如：I take it （that） he will come on time. 我認(rèn)為他會準(zhǔn)時(shí)來的。You can put it that it was arranged before. 你可以說這是以前安排的。Rumor has it that the defence minister will soon resign. 據(jù)傳聞，國防部長不久就要辭職。 說明：能用于此結(jié)構(gòu)的動詞不多，常見的有 have, take, put 等。2. 動詞 + it + when （if）- 從句

5、。某些表示 “喜、怒、哀、樂 ”的動詞，如 like, enjoy, love, hate dislike, appreciate, prefer 等，往往不能直接接賓語從句，如：I like it that you came. 你來了，我很高興。I dislike it when you whistle. 我不愛聽你吹口哨。We really appreciate it when she offered to help. 她來幫忙了，我們十分感激。I ' d prefer it if I didn' t have to do sdm是我不必做那么多工作，好就太好了。3. 動詞

6、 + prep + it + that- 從句。 that 引導(dǎo)的賓語從句不能直接作介詞的賓語。如：See to it that you' re not late注意千.萬不要再遲到。Look to it that this doesn' t happ注意不aH再發(fā)生這種事。I can ' t answer for it that he will come我不能保證他會來。You may rely on it that he' ll come to m你放心屮.他會來接你 的。You may depend on it that we shall always h

7、elp you. （盡管放心，我們會隨時(shí)幫你的。 ） Would you see to it that she gets home early （你負(fù)責(zé)保證她早到家，好嗎） He insisted on it that he was innocent. （他堅(jiān)持說自己是無辜的。 ）說明：能用于此結(jié)構(gòu)的動詞不多，常見的有see to, look to, insist on, stick to, depend on,answer for 等。4. 動詞+ it +介詞短語+ that-從句。由及物動詞與介詞組成的固定搭配中，賓語從句若作該動詞的賓語時(shí)，須借用it。如：I owe it to you

8、 that I am still alive. 多虧有你我才仍然活著。I took it for gra nted that he would help us.我認(rèn)為他會幫助我們的。I leave it to your own judgeme nt whether you should do it.（我讓你自己判斷這事是否該做。）We owe it to you that there wasn' aacideoLi （多虧了你才沒有發(fā)生嚴(yán)重事故。 ）說明：能用于此結(jié)構(gòu)的動詞不多，常見的有take it for gran ted, bring it to sb' s atte n
