在近幾年的高考試題中，對it的考查成了一個(gè)不可忽略的考點(diǎn)，它主要涵蓋了以下幾個(gè)方面：

一、指代上文提到的事或物,作主語或賓語。

1. ——Have you heard the latest news? (2007全國卷Ⅰ)

——No, what ____?

A. is it B. is there C. are they D. are those

答案為A。指代上文中的news。news為不可數(shù)名詞，不能被they，those等代詞所指代。

2. The doctor advised Vera strongly that she should take a holiday, but ____ didnt help. (2005全國卷Ⅲ)

A. it B. she C. which D. he

答案為A。but是并列連詞,所以逗號前后的兩個(gè)句子是并列的,后一個(gè)分句的主語是it,指代前面的分句The doctor advised Vera strongly that she should take a holiday.

二、it指代環(huán)境、情況、天氣、季節(jié)、時(shí)間、距離、價(jià)格等。
