Revising useful structures

1. The three

Non-Finite Verbs and their difference between them.

doing (现在分词) : 表主动，表进行

非谓语动词：

done (过去分词)：

表被动，表完成

to do (不定时)：表目的，表将来

2. Look at thesentences and use right forms to fill in the blanks. ①

______ (surround) by whaling boats, the whale has no place to go. ②

With a lot of homeworh ____ (do), I can not go out with you. ③

______ (see)from space, we can not see the Great Wall. Step two The usage of present participle (-ing). 现在分词主动语态的一般式表示与谓语动词所表示的动作同时发生，完成式表示的动作在谓语动词所表示的动作之前发生，常作状语。

现在分词一般时的主动形式: doing 被动形式: being done 现在分词完成时的主动形式: having done 被动形式: having been done 1.

doing 做主语

1). 单个doing 做主语时，谓语动词常用单数形式。

Eg:

Seeing is believing. 2). doing做主语时，常用it做形式主语，把真正的主语放后面。

Eg:

It is no use talking with such a person like him. 2. doing 做宾语

某些动词或动词短语后面只能接doing做宾语。常见的动词及短语有admit, avoid, consider, delay, deny, endure, enjoy, escape, excuse, fancy, finish, forbid, imagine, mind, miss, dislike, permit, postpone, practise, require, risk, stop, suggest, can't help, feel like, give up, keep on, objiect to, put off…

Eg: 1). Hearing the news, he couldn’t help crying.

2). He doesn’t like the person and always avoids meeting him.

3. doing 做定语

doing作定语，当分词单独做定语时，放在所修饰的名词前；如果是分词短语做定语放在名词后。

Eg: 1). In the following years he worked even harder.

2). The man speaking to the teacher is our monitor's father.

4. doing 做表语

doing做表语时，常放在系动词的后面。

eg: 1). The film being shown in the cinema is exciting.

2). The present situation is inspiring.

5. doing 做宾语补足语

在英语中，某些词后面接doing作宾语补足语. 常用的有see, watch, hear, feel, find, get, keep, notice, observe, listen to, look at, leave, catch…

eg: 1). Can you hear her singing the song in the next room?

2). He often keeps his children reading in the room for one hour.

6. doing 做状语

doing做状语时，常常与句子的主语构成逻辑上的主动关系。

Eg: 1). Working in the factory, he was an advanced worker.

2). ______ (see)from space, we can not see the Great Wall.
