it的用法讲解---绝对经典系列
it的用法讲解---绝对经典系列在英语学习中，“it”这个词虽然简单常见，但其用法却丰富多样，稍不注意就可能会产生混淆。
今天，咱们就来系统地梳理一下“it”的各种用法，让您对它有一个清晰透彻的理解。
首先，“it”最基本的用法是作人称代词，用来指代前文提到过的事物或情况。
比如说，“I bought a book yesterday It is very interesting”（我昨天买了一本书，它非常有趣。
）这里的“it”就指代前面提到的“book”。
“it”还可以用来指代时间、天气、距离、温度等抽象概念。
例如，“It's five o'clock”（现在五点钟了。
）这里的“it”指的是时间。
再比如，“It's raining”（正在下雨。
）这里的“it”指的是天气。
“It's about five kilometers from here to the zoo”（从这里到动物园大约五公里。
）此句中的“it”则表示距离。
“it”作形式主语或形式宾语也是常见的用法。
当句子的主语或宾语过长，为了避免头重脚轻，我们就会用“it”来充当形式上的主语或宾语，而把真正的主语或宾语后置。
比如，“It's difficult to learn a foreign language”（学习一门外语很难。
）这里真正的主语是“to learn a foreign language”，“it”只是形式主语。
再看这个句子，“I find it hard to understand this passage”（我发现理解这篇文章很难。
）这里“it”是形式宾语，真正的宾语是“to understand this passage”。
在强调句中，“it”也有着重要的地位。
强调句的结构是“It is/was ＋被强调部分＋ that/who ＋其他部分”。
比如，“It was Tom who brokethe window”（是汤姆打破了窗户。
