（二）本章語法
1. 分詞的結構
我們所說的分詞包括現在分詞和過去分詞
現在分詞結構主要有：doing，being done，having done，having been done
過去分詞只有done
2. 分詞的用法
（1）分詞做表語，
如：The basketball match was very exciting.
He was surprised to hear the news.
（2）分詞做定語
如：The sleeping boy is my nephew.
The boy sleeping on the chair is my nephew.
This shop only sells used books.
The city destroyed in the World War Two is now very beautiful.
（3）分詞做賓補
如：I saw him cooking just now.
He found his room cleaned.
（4）分詞做狀語，做狀語的分詞一般在句首，表示時間，方式，條件和原因，起到時間，方式，條件和原因狀語從句的作用；放在句末一般表示伴隨著謂語動詞的一種情況或結果。
如：Entering the room, I found myself alone.
Being watched, he said nothing.
Crowded with people, the room can not hold any more.
Having finished his homework, he went out.
Having been asked to leave, he prepared his luggage.
Using this pen, you can write more fluently.
Considered from this point of view, this question is important.
Being busy, he didn’t go to the party.
Greatly inspired by the teacher’s words, they’ve made up their mind to study hard.
The girl went to school wearing a red skirt.
The professor walked to the lab, followed by some students.
While waiting there, he thought of a good idea.

On hearing the news, we were all surprised.
（5）分詞的時態和語態
只有現在分詞才有時態和語態形式的變化，而且只有它做狀語和定語時才有，表語和賓補時的現在分詞一般只用普通式doing。
現在分詞一般表示與謂語動詞同時發生或先于謂語動詞發生的動作。
如：He came into the room, singing happily.
Hearing the news, she burst into laugh.
現在分詞的完成式表示發生在謂語動詞之前的動作，
如：Having eaten too much, he nearly couldn’t stand up.
Not having seen the result of the game, he asked the man next to him.
現在分詞的被動語態一般表示一個被動的動作正在進行，
如：The man being operated on is his brother.
Being heated, water gives out steam.
現在分詞的被動語態完成式一般表示一個被動的動作先于謂語動詞已完成，
如：Having been surrounded, the enemy had to lay down their weapons.
Having been told not to go, they stayed there.
過去分詞只有一種形式，同時表示被動與完成，與現在分詞被動完成式相似，但后者更強調完成。
如：Given a good chance, he will succeed.
Having been given enough money, he set off.
