The use of “it” It的用法

It was very helpful. 我和经理谈了一次话，对我非常有帮助。 It happened during the Long March. 事情发生在长征的时候。（指下文所说的事情） Air is everywhere, it gives life to every living thing. 空气到处存在，它给一切生物以生命。 It’s the students’ shouting. 那是学生们在叫喊。（指上文所说的事情） ⑵起指示代词的作用，指一个人或事物。 ——Who is knocking at the door? 谁再敲门？ ——It’s me. 是我。

It is cold today, isn’t it? 今天很冷，是不是？ I hope it will be fine tomorrow. 我希望明天是个好天气。 It is raining hard. 雨下得很大。 Ⅱ、引词it（引词anticipatory） ⑴作形式主语（formal subject） 当主语是动词不定式、动名词、主语从句时，往往把主语放在谓语动词 之后，而把 it 放在句首。这个it称为引词，作形式主语，放在谓语动词后的 主语是真实主语。 ①真实主语是动词不定式，如： It is your duty to pay taxes. 纳税是你们的责任。 It is possible to learn typewriting very quickly? 能够很快地学会打字吗？ It is necessary for us to have some exercise every day. 我们每天需要一些运动。
4
②真实主语是动名词，如： It’s a waste of time making such an experiment. 做这样一种实验是浪费时间。 It is no use talking. 光说没有用。 Is it any good trying? 试有用吗？ ③真实主语是主语从句，如： It doesn’t matter whether we start now or later. 我们现在开始，还是以后开始没有关系。 It is clear that he means well. 很明显，他的用意是好的。 It is said that he has become a Party member. 听说他已经入党了。 It is a pity that you didn’t go to see the film. 你没去看这个电影，真是可惜。 ⑵作形式宾语（formal object） 当复合宾语中的宾语是动词不定式、动名词和宾语从句时，往往把宾语 放在宾语补足语的后面；而用引词it 作形式宾语，放在宾语补足语之前；放在宾语 补hard to control inflation. 他们发现控制通货膨胀是困难的。 She feels it very difficult to answer the question. 这个问题很难回答。 He feels it his duty to help others. 他感到帮助别人是他的责任。 I think it no use telling them. 我认为告诉他们没有用。 We have made it clear that agriculture is the foundation of the national economy. 农业是国民经济的基础，这我们已经说清楚了。 ⑶引词it用在强调结构中： 当我们要强调句子的某一部分（通常总是主语、宾语或状语）时，常用 下面结构：It is (was)+被强调的部分+who (that)… 被强调的部分指人时，用who，其它情况用that。例如原来的句子为： Professor Zhang taught us English every Friday morning. 张教授每星期五上午教我们英语。 It was Professor Zhang who taught us English every Friday morning. （强调主语）
