It" 做形式宾语用法总结

当不定式（短语）、动名词（短语）或从句在某个句子中作

宾语时，为保持句子结构平衡，避免句式结构的混乱，常用it作形式宾语，而将真正的宾语放在句尾，构成“动词＋it＋宾语补

足语＋不定式（动名词或从句）”结构，也可称作“6123结构”。此时it仍只起先行引导作用，本身无词义。它可以代替三种形式：不定式、动名词和宾语从句。it作形式宾语时，需具备两个条件：① 真正的宾语是不定式、动名词或从句; ② 有宾

语补足语，具备了这两个条件，形式宾语it一定要用。⒈ i t代替不定式短语think/ find/ feel/ consider/ make/ regard…+ it +形容词/名词 + 不定式短语如：①I find it pleasant to work with him、

(it 作形式宾语，代替不定式短语to work with him)②They felt it difficult to finish the work in such a short time、

（ it 作形式宾语，代替不定式短语to finish the work in such a short time）③She thinks it her duty to help us、（ it 作形式宾语，代替不定式短语to help us）④I think it my honor to be invited to speak here、

letters in Chinese、（ it 作形式宾语，代替不定式短语to write letters in Chinese）⑥All these noises made it impossible for me to go on with the work、（ it 作形式宾语，代替不定式短语to go on with the work）⒉ it代替动名

词短语( 这只限于少数句型，在多数情况下用不定式时更多一些)如：①The professor considers it no good reading without understanding、②Do you conside r it any good trying again?

③He found it useless( no use)

arguing with him、④He thought it absolutely senseless attempting the impossible、⑤I don’t think it worthwhile going to such a place、

⒊ it代替宾语从句：

如：①We all thought it a pity that the conference should have been cancelled、②I took it for granted that they were not coming、③I’ll see to it that everything is ready in time、“it”的特殊用法常出现在以下几种结构中。

A、动词＋it＋when / if 从句。常见于appreciate, enjoy, like, dislike, love, hate, prefer等少数动词之后。We would

much appreciate it if you could do us that favour、Id prefer it if I didnt have to finish the work、

B、动词+ it + that从句。常见于like, take, have, put 等少数动词之后（it相当于that从句的同位语）。I take it that they will succeed sooner or later、The newspapers have it that some Japanese firms have gone bankrupt、Rumor has it that Mary is getting married、 I take it that you have been out、Let me come and stay、 You can put it that it was arranged before、

C、动词 + it + 介词短语 + that从句。常见于bring it to ones attention; owe it to sb; take it for granted 等结构中。I owe it to you that I finished my work in time、Dont take it for granted that they will support you、

95、They havent made it known where the meeting is to take place、易混用其他句型

⒈ There is something/nothing wrong/ the matter with sb、/ sth、如：There is nothing wrong /the matter with him、He’s just pretending、他没什么事，他只是在装呢。

⒉ There is no doubt about…对…毫不怀疑There is no doubt that…对…毫不怀疑如：①There is no doubt about his suitability for the job、毫无疑问，他适合这个工作。②There is no doubt about the fact、关于这个事实毫无怀疑。

把握“it”用作形式宾语的特殊结构（附答案） 在英语中，当动词不定式、动名词或从句在句中充当宾语且其后又带有宾语补足语时，习惯上要在宾语补足语前使用一个没有具体意义的形式宾语it，而将真正的宾语移到补足语的后面，构成“动词＋it＋宾语补足语＋不定式（动名词或从句）”结构。如： She felt it her duty (to take good care of them). 括号内为真正宾语 她感到好好照顾他们是她的责任。 I think it no good going there now. 我认为现在去那里没有好处。 The headmaster has made it clear (that the school meeting will not be put off). 校长说得很清楚校会不会推迟。 但我们常会碰到it用作形式宾语时之后没有形容词或名词作宾语补足语的情况，这一点在近几年高考试题中经常涉及，需引起同学们的注意。 I hate_____ when people talk with their mouths full. (NMET 1998) A. it B. that C. these D. them (答案为: A) 我讨厌人们一边吃饭一边说话。 I like _____ in the autumn when the weather is clear and bright. (全国卷2004) A. this B. that C. it D. one (答案为: C) 我喜欢秋天晴朗的天气。 以上这两道高考题中，it用作形式宾语，它的真正的宾语则是由when引导的从句。“it”的这种特殊用法常出现在以下几种结构中。 A. 动词＋it＋when / if 从句。常见于appreciate, enjoy, like, dislike, love, hate, prefer等少数动词之后。We would much appreciate it if you could do us that favour. 要是你们能帮我们这个忙，我们将非常感激。 I'd prefer it if I didn't have to finish the work. 要是我不必完成那项工作，那就太好了。 B. 动词+ it + that从句。常见于like, take, have, put等少数动词之后。 I take it that they will succeed sooner or later. 我认为他们迟早会成功的。 The newspapers have it that some Japanese firms have gone bankrupt. 报上说一些日本商号破产了。 C. 动词+ it + 介词短语+ that从句。常见于bring it to one's attention; owe it to sb; take it for granted 等结构中。 I owe it to you that I finished my work in time. 多亏有你我才及时完成了工作。 Don't take it for granted that they will support you. 不要想当然地认为他们会支持你。 D. 动词+ 介词(短语) + it + that从句。常见于answer for, depend on, rely on, insist on, look to, see to, stick to 等结构中。 I'll see to it that everything is ready in time. 我将负责按时做好一切准备。 You may depend on it that Tom will help you with your English. 你放心，汤姆会帮助你学英语的。 E. 动词+ it +过去分词+从句。常见于几个可以带过去分词作宾语补足语的动词之后。 I heard it said that that factory was founded in 1995. 我听说那家工厂是1995年创建的。 They haven't made it known where the meeting is to take place. 他们没有宣布会议在哪里召开。

(完整版)It作形式宾语用法总结

" It" 做形式宾语用法总结 当不定式（短语）、动名词（短语）或从句在某个句子中作宾语时，为保持句子结构平衡，避免句式结构的混乱，常用it作形式宾语，而将真正的宾语放在句尾，构成“动词＋it＋宾语补足语＋不定式（动名词或从句）”结构，也可称作“6123结构”。此时it仍只起先行引导作用，本身无词义。它可以代替三种形式：不定式、动名词和宾语从句。 it作形式宾语时，需具备两个条件：①真正的宾语是不定式、动名词或从句; ②有宾语补足语，具备了这两个条件，形式宾语it一定要用。 ⒈ it代替不定式短语think/ find/ feel/ consider/ make/ regard…+ it +形容词/名词+ 不定式短语如： ①I find it pleasant to work with him. (it 作形式宾语，代替不定式短语to work with him) ②They felt it difficult to finish the work in such a short time. （it 作形式宾语，代替不定式短语to finish the work in such a short time） ③She thinks it her duty to help us. （it 作形式宾语，代替不定式短语to help us） ④I think it my honor to be invited to speak here. （it 作形式宾语，代替不定式短语to be invited to speak here） ⑤Tom didn’t find it difficult to write letters i n Chinese. （it 作形式宾语，代替不定式短语to write letters in Chinese） ⑥All these noises made it impossible for me to go on with the work. （it 作形式宾语，代替不定式短语to go on with the work） ⒉ it代替动名词短语( 这只限于少数句型，在多数情况下用不定式时更多一些) 如： ①The professor considers it no good reading without understanding. ②Do you consider it any good trying again? ③He found it useless( no use) arguing with him. ④He thought it absolutely senseless attempting the impossible. ⑤I don’t think it worthwhile going to such a place. ⒊ it代替宾语从句： 如： ①We all thought it a pity that the conference should have been cancelled. ②I took it for granted that they were not coming. ③I’ll see to it that everything is ready in time. “it”的特殊用法常出现在以下几种结构中。 A. 动词＋it＋when / if 从句。常见于appreciate, enjoy, like, dislike, love, hate, prefer等少数动词之后。 We would much appreciate it if you could do us that favour. I'd prefer it if I didn't have to finish the work. B. 动词+ it + that从句。常见于like, take, have, put等少数动词之后（it相当于that从句的同位语）。 I take it that they will succeed sooner or later. The newspapers have it that some Japanese firms have gone bankrupt. Rumor has it that Mary is getting married. I take it that you have been out. Let me come and stay. You can put it that it was arranged before.
