it在句子中的用法总结
it在句子中的用法总结一、IT在句子中的基本用法IT是英语中一个常见的代词，表示“它”。
在句子中，IT有以下几种基本用法。
1. 作为主语：当句子的主语是不具体或未知的时候，可以使用IT作为占位符。
例如：“It is raining.”（下雨了）这个句子中，主语是下雨这个动作，并没有具体的人或物承担该动作。
2. 作为形式主语：有些动词需要跟形式主语it连用，而真正的主语放在后面的从句中。
例如：“It is important to learn a second language.”（学习第二门语言很重要）这个句子中，“to learn a second language”是真正的主语，而it充当形式主语引导句子。
3. 作为强调结构：在强调特定信息时，可以使用“It is…”结构。
例如：“It was John who broke the window.”（是约翰打碎了窗户）这个句子中，通过加强重要信息“John”来引起对他行为的关注。
二、IT在不同情况下的具体应用1. 时间和天气描述：IT经常用于描述时间和天气条件。
例如：“What time is it?”（现在几点了？）和“It's hot today.”（今天很热）。
在这种情况下，IT没有特定的指代，只是用于描述一个普遍的信息。
2. 物体或事物说明：IT也用于指代不具体的事物或对象。
例如：“I can't findmy book. Have you seen it?”（我找不到我的书了，你看见它了吗？）在这个句子中，it用来代替已知的书。
3. 引入后面的从句：在想要引入一个补充信息或解释时，一般使用It +that/whether/if来引导从句。
例如：“It is not clear whether he will come or not.”（他是否会来还不清楚）。
在这个句子中，“whether he will come or not”是由it引导的从句。
