不定代词it的用法

不定代词it的用法

不定代词it的用法一、不定代词it的基本用法在英语中，不定代词it充当性别不明、指代某个特定事物或概念等的角色。

它是一个非常常用且灵活的代词，能够承担多种种类和功能。

在下面的段落中，我将会详细介绍it作为不定代词的几种常见用法。

1. 作为形式主语或形式宾语在很多情况下，人们使用it作为形式主语或形式宾语来引导句子。

这是因为句子的真正主语或宾语可能是一个复杂的短语或从句，而使用it可以把这个复杂结构移到句子后面而不影响主谓结构。

例如：- It is important to have a healthy diet.（拥有健康饮食习惯很重要。

）- I find it difficult to understand this concept.（我发现理解这个概念很困难。

）2. 作为反身代词当需要表示某人自己的行动时，人们通常会使用反身代词来强调动作涉及到了自己。

在没有特指具体人物时，可以使用it作为反身代词。

例如：- I really enjoyed the concert last night. It was a great experience!（我昨晚非常享受这场音乐会。

它是一次很棒的体验！）3. 引导形式主语从句或形式宾语从句在某些情况下，it作为形式主语从句或形式宾语从句的引导词，用来替代真正的主语或宾语，以使整个句子结构清晰明了。

例如：- It is believed that exercise can improve mental health.（人们认为运动可以改善心理健康。

）- I find it hard to believe that she won the lottery.（我发现难以相信她中了彩票。

）二、不定代词it的特殊用法除了上述基本用法外，不定代词it还有一些特殊的使用方式。

在接下来的几个段落中，我将逐一介绍这些特殊用法。

1. 强调句型当想要强调一个特定的信息时，可以使用强调句型来突出该信息，并且通常把被强调的部分放在it后面。

高考重点：It的用法以及含有it的句型

高考重点：It的用法以及含有it的句型

高考重点：It的用法以及含有it的句型英语中it 一词结构看似简单，但其词义广泛，使用范围很广，常令一些初学者感到头痛。

It用法及其句型和固定搭配，是英语语法的重点、难点，又是近几年考试的热点,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。

因此在复习中应给予足够的重视。

下面笔者就it的用法简单归纳如下。

一、代替上文中提到过的人或事物。

指代人时，一般用于小孩或身份不十分明朗的人。

1) －Who is the baby? －It‘s my teacher’s son．2) －Who is that gentleman? －It's my friend Tom．He(不可用It) wants to see you．不定代词one 指代前文提到的同类事物之一，而it 特指上文中提到的同一事物。

试对比：This pair of shoes is small. May I have another one？（泛指的另一双）这又鞋子太小了，再拿一双给我看看好吗My pen is missing.Ican’td find it.我的钢笔丢了找不到了(it指my pen)二. it 作为无人称动词的主语，表示天气，时间，距离，环境情况等等。

这时的it 不指某个具体的东西。

没有明确的含义。

译成汉语可不必译出来。

如1).It‘s half an hour’s walk from here to our school．从这儿到我们学校是步行一个小时的路程2) It‘s nice and warm here．这里非常暖和3) But it's two o'clock now, and it's time for us to go to school．两点了该是上学的时间了4) It’s quite close in the room . Let’s open the window for a while。
