[名校联盟]新疆新源县第八中学高考英语《it的用法》复习课件+资料（3份）

it的用法 【高考走向】It的用法在高考中也是重现率较高的语言点。其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。 14.The doctor thought______would be good for you to have a holiday.（2010全国卷II） A.this B.that C.one D.it 答案：D 解析：考查It的用法。It的两个重要用法是作形式主语和形式宾语。本题考查形式宾语，it在这里代指后面的真正宾语to have a holiday。 （2010陕西卷短文改错） My sister saw a lovely cup when we are shopping the other day. She liked it at once. Then she bent down and picked up to look at a price on it. ... 解析：pick up中间应加上it，指代上文提到的a lovely cup. it的基本用法 一、代词it （1）用作人称代词，代替前文提到过的事物。 That vase is valuable. It’s more than 200 years old. 那个花瓶很珍贵，它有200多年的历史。 I love swimming. It keeps me fit. 我喜欢游泳，它能使我保持健康。 （2）用以代替提示代词this, that。 —What’s this? —It’s a knife. —Whose watch is that? —It’s mine. （3）起指示代词的作用，指一个人或事物。 —Who is knocking at the door? —It’s me. （4）表示天气、气候、温度、时间、地点、距离、环境等意义的句子中。 It is half past three now. 现在是三点半钟。 It is six miles to the nearest hospital from here. 这里离最近的医院也有六英里。 It was very cold; it snowed and grew dark. 天气很冷；天下着雪，渐渐地变黑了。 It was very noisy (quiet) at the very moment. （5） it也常用来表示一般的笼统的情况。如： It’s awful—I’ve got so much work I don’t know where to start. 糟透了——我有这么多工作要做我不知从何开始。 How is it going with you? Take it easy. it与one的区别：这两个词都可以代表前面说过的名词，但it用于同名同物的场合；one则用于同名异物的场合。 — Do you still have the bicycle? — No, I have sold it. — Is this knife yours? —No. It is Xiao Zhang’s. Mine is the one on the desk. it与that的区别：两词都可代替某一特定名词，但that指同一类，并非同一个。 The climate of South China is mild（温和的）; I like it very much. （it指the climate of South China） The climate of South China is much better than that of Japan. （that指the climate） 二、引导词it it充当形式主语或形式宾语，本身无意义，只起一种先行引导的作用。后面的真正主语或真正宾语通常是不定式结构、-ing分词结构或名词性从句。 （1）用作形式主语 It is difficult to translate this article. 翻译这篇文章很难。 It is getting harder every day for a lazy man to get a living. 懒汉谋生是日益困难了。 What time would it be most conven
