3. 作形式主语英语中不定式、动名词、主语从句在作主语时，主语往往显得很长，使整个句子看上去有点头重脚轻，这时就需要借助“It”作形式上的主语，而把整个句子的主语移到句子后边去，使句子看上去平稳一些。

It is difficult to study and work at the same time.一边工作一边学习很难。

It is very clear that the elephant's l eg is round a nd tall like a tree.大象的腿跟树干一样圆而高，这点显而易见。

it考点讲义：it用作形式主语和形式宾语的用法归纳总结- 高考英语语法二轮复习专题.docx

高中英语语法高考二轮复习it考点讲义【精讲版】it用作形式主语和形式宾语的用法归纳总结一、用作形式主语当不定式、动名词、从句等用作主语时，避免头重脚轻，通常在句首使用形式主语厄而把真正的主语放在句子末尾。

如：It is stupid to do such a thing.做这种事真蠢。

It's no good sitting up too late.熬夜没有好处。

It is necessary that he should be sent there at once.有必要马上派他到那里去。

注：类似以下句子中的il也可视为形式主语：It happened that the harvest was bad in 1988.碰巧1988 年的收成很不好。

It seems that she is afraid to tell them about it.似乎她怕将此事告诉他们。

二、用作形式宾语当不定式、动名词、从句等用作宾语且其后跟有宾语补足语时，就应在宾语补足语前使用形式宾语，而将真正的宾语移至句末。

如：I've made it a rule never to hurry,我已养成凡事从容不迫的习惯。

Do you think it possible to root out crime?你认为可以根除犯罪吗？He found il difficult to breathe at high altitudes.他觉得在高空呼吸困难。

注：通常意义的形式宾语主要见于真正宾语为不定式、动名词、从句等且其后跟有宾语补足语时的情形，即用于“动词+it+宾语补足语+真正的宾语”这样的结构，但以下两类形式宾语却比较特殊，其后没有宾语补足语:1.由于介词后通常不能直接跟that从句作宾语，有个别特殊结构就在介词后先接it作形式宾语，再跟that从句。

如：You may depend on it that it is true.你可以相信这是真的。

it的用法讲解---绝对经典系列嘿，伙计们！今天我们要来聊聊一个超级神奇的单词——it。

这个词在我们的日常生活中无处不在，它既可以作为主语、宾语，也可以作为形容词、副词。

而且，它还可以指代很多东西，比如动物、物品、技术等等。

那么，it到底是怎么来的呢？它又有哪些用法呢？别着急，我们一一来看。

我们来说说it的基本用法。

it作为一个单词，最基本的意思就是“它”。

比如说，我们看到一只猫，就可以说：“It is a cat.”(这是一只猫)。

it也可以作为主语或宾语使用。

比如说，我们可以说：“It is raining outside.”(外面正在下雨)或者“I saw it at the store.”(我在商店里看到了它)。

这里，it就是一个主语，表示下雨这个动作。

而当我们把it作为宾语时，它就表示被下雨这个动作所影响的对象。

比如说，我们可以说：“The book got wet because of it.”(因为下雨，书湿了)。

这里的it就是宾语，表示书这本书。

接下来，我们来看看it的其他用法。

首先是作为形容词使用。

这时候，it通常用来修饰名词，表示这个名词的特征或者属性。

比如说，我们可以说：“This is a nice it.”(这是一个不错的it)。

这里的nice就是形容词，修饰it这个名词。

而当我们用it来修饰动词时，它就表示这个动作的结果或者状态。

比如说，我们可以说：“He fixed it quickly.”(他很快就修好了它)。

这里的quickly就是副词，修饰fixed这个动词。

除了这些基本用法之外，it还有很多其他的特殊用法。

比如说，我们可以用it来指代上文提到的某个事物或者概念。

这样一来，我们就可以避免重复使用同一个词，让文章更加简洁明了。

it和the的用法

it和the的用法一、"it"的用法1. 作代词：指代不具体的事物或概念在英语中， "it"通常用作一个不具体的事物或概念的代词。

它可以指代单个名词，也可以引出整个句子所讨论的主题。

例如：- I bought a new phone yesterday. It is very expensive.（我昨天买了一部新手机。

它非常贵。

）在这个例句中，"it"指代的是前面提到的"new phone"，用来引出接下来对手机价格的描述。

- It is raining outside, so remember to bring an umbrella.（外面正在下雨，所以记得带把伞。

）这里，“it”指代“rain”，并引导着后文关于雨下起来原因或结果的详细解释。

2. 作形式主语和形式宾语在英语中，当我们想要强调某种状态或行为时，常常使用“it”作为形式主语。

例如：- It's important to take care of our health.(保持健康很重要。

)这里，“It's important”是一个固定搭配，表示强调某种观点或态度，并没有真正的主语。

然而，在口头表达与书面表达中都十分常见。

3. 引导无人称句在英语中，“it”经常用作无人称句型中的主语，特别是当简单的真实陈述时。

例如：- It's cold today.（今天很冷。

）这里，“it”没有具体指代的对象，仅表示当前气温的状态。

4. 引导时间、天气和季节等描述形容时间、天气或季节等无生命的现象时，通常使用“it”。

例如：- What time is it?（现在几点了？）在这个例句中，“it”用于询问时间。

- It is sunny this afternoon.（今天下午阳光明媚。

）这里，“it”用于表达此刻的天气状况。

二、“the”的用法1. 特指某一个人或事物“the”是英语中最常见的冠词，也用来特指单数或复数名词。
