高中英语必修三语法知识

使用被动语态应注意的几个问题：

1. 不及物动词无被动语态。

What will happen in 100 years.

The dinosaurs disappeared about 65 million years ago.

2. 有些动词用主动形式表示被动意义。

This pen writes well.

This new book sells well.

3. 感官动词或使役动词使用省略to的动词不定式，主动语态中不带to ，但变为被动语态时，须加上to 。 例：make somebody do something→somebody+ be +made to do something

see somebody do something→somebody +be +seen to do something

A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by. The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.

4. 如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。

He gave me a book.→A book was given to me by him.

He showed me a ticket.→A ticket was shown to me by him.

My father bought me a new bike. →A new bike was bought for me by my father.

高中英语单词讲解教案4

it的概念：

it可用作人称代词、指示代词、先行词及引导词等。

it 的用法：

1、it可指天气、温度、时间、距离等 。

如：It is cold today, isn't it?

2、用作人称代词，代替前文提到过的事物。

如：The dog is not acold-blooded animals. It doesn't need to hibernate.

3、为避免重复，it可用来代替前面说过的短语或句子。

如：I tried to persuade my father to give up smoking, but found it impossible. (it=to persuade my father to give up smoking)

4、代替指示代词this，that。

如：—What's this?

—It's an album.

—Whose new bike is that?

—It's Mary's.

注：it与one，that的区别：

it=the(this, that)+名词，特指并且代替前面所提到的某特定事物。

如：He's bought a new car, so he drives it everywhere to show ito ff.

one=a+名词，one指前面提到的同类事物中的不同的另一个。

如：He needs a computer, but he can't afford one.

that=the+名词，that指代的名词与前面的名词属于同一类，但不属同一个。

如：The population of China is larger than that of Japan. that指代population，但其后有一个of短语作定语，以区别于the population of China。

注：it与that的异同：

it指同一事物，that指同类但并不是同一事物。

如：I like the climate of Kunming more than that of Beijing.

The climate of Kunming is mild, and I like it.

5、It/This/That+be+the first(second, third...) time+that-clause 这个句型表示截止到说话时为止的某人的一种经历，关键是注意time前有序数词，主句是一般现在时is时，从句要用现在完成时;如果主句用一般过去时was时，则从句须相应地用过去完成时。

如：This is the first time(that) these Europeans have visited the Great Wall.

It was the fifth time(that) I had paid a friendly visit to America.

6、在一些相对固定的词组中，没有特殊含义，经常不翻译。

如：He's never really made it as an actor. 作为演员，他从未获得过真正的成功。

It is my turn. 轮到我了。

强调句中的it：

可以用来改变句子结构，使句子的某一成分得到强调：

1)强调句的基本句型it's/was+被强调成分+that/who+其他成分

原句：I told Jim the news in our office yesterday.

强调主语：It was I that/who told Jim the news in our office yesterday.

强调宾语：It was Jim that I told the news in our office yesterday.

或：It was the news that I told Jim in our office yesterday.

强调地点状语：It was in our office that I told Jim the news yesterday.

强调时间状语：It was yesterday that I told Jim the news in our office.

2)强调句的一般疑问句型Is/Was+it+所强调部分+that/who...?

如：Was it you that told Jim the news in your office yesterday?

3)强调句的特殊疑问句型疑问词+is/was+it+that/who...?

如：Who was it that told Jim the news in your office yesterday?

【注】强调句与主语从句虽然在形式上很相似，即都含有it is(was)...that。但，区别在于：强调句去掉it is(was)…that之后，句子结构仍然完整，而主语从句却不能这样。

如：(It is)our hope(that) the two sides will work towards peace.

解析：去掉It is…that之后，句子是不成立的。由此得出该句不是强调句，而是一个简单的主语从句，it是形式主语，从句是真正的主语。
