Step I Revision

Check the students’ homework and ask the student to act out the play. T: Yesterday I asked you to prepare for the play-acting. Have you prepared? Now I want to ask three students to have a try. After they have finish, make some comments on their performance. Step II Word Study Ask the Ss to finish Exx.1 and 2 in learning about language. Then check the answers with the class. T: There are some “in”

expressions. You should pay attention: there is not “the” in these expressions. Do you know the meaning of them? Show the followings:

in return

回报

in trouble

处于麻烦中

in disguise

伪装

in amazement

惊愕

in pain

痛苦地

in delight

高兴地

in shock

震惊地

Step III Grammar First ask the students to find out the examples of the past participle as the adverbial in the play. Sample sentences: 1.

An expert in phonetics, convinced that the quality of a person’s English decides his/her position in society. P28 2.

But, sir, (proudly) once educated to speak properly, the girl could pass herself off in three months as a duchess at an ambassador’s garden party. P30

Explanations: T: The past participle as the adverbial is a very important grammar, and it can indicate time, condition, reason, and way. We can add when/while/if or other conjunctions before the past participle in order to make the meaning more clearly. For example: Show the following: If bitten by a snake, you should send for help and don’t walk. The room, although supposed to be kept locked, was often left open. T: Now please look at the following examples. Can you rewrite these sentences? Show the following 1.

Given more time, we could do it better(When / If…)

2.

Heated to a high temperature, water will change to vapor. (When / If…)

3.

Disturbed by the noise, we had not finishes the meeting early. (As…)

二．重难点辨析

不表被动的特殊情况

1.有些过去分词因来源于系表结构，作状语时不表被动而表主语的状态。

lost (迷路);

seated (坐);

hidden (躲);

lost / absorbed in (沉溺于);

born (出身于);

dressed in (穿着);

2.

由某些动词后面加-ed转化来的形容词也具有此用法。

如：frightened, satisfied, tired, disappointed等。

Lost / Absorbed in deep thought, he didn't hear the sound.

Surprised at what had happened, Tom didn’t know what to do.

三．使用过去分词作状语时容易错的两种情况

1. 忽视了分词作状语时其逻辑主语必须是句中主语(或主动或被动)。如: If heated, _______.

A.people can turn water into gas

B. one can change ice into water C. ice turns into water

D. people get water from ice 若分词主语与句中主语不一致,则可以用其他方法来修正: ①

给分词添加自己的主语,构成独立主格结构或改变语态。

②改为相应的状语从句来表达。

③用with复合结构等。

如:完成作业后,孩子们出去踢足球了。

Finished their homework, the children went out to play football.

→Their homework finished, the children went out to play football.

(独立主格结构)

→Having finished their homework, the children went out to play football.

(现在分词完成形式)

→With their homework finished, the children went out to play football.

(with的复合结构)

→After finishing their homework, the children went out to play football.

(介词+动名词)

有些含有分词的固定插入语, 其逻辑主语不要求与主语一致。如:

judging from(从…….来判断);

generally(frankly/exactly/…./ )speaking

一般地(坦率地/确切地)说; considering(考虑到)……;

talking of(说到)….;

supposing that(假使)….;

seeing that(鉴于)…..等。

如:

Considering his health, he was made to stay at home。

2. 不能正确区分doing(现在分词)和

done(过去分词)的用法

(1)______ the progamme, they have to stay there for another two weeks.

A. Not completing

B. Not completed

C. Not having completed

D. Having not completed

(2)_______ many times, he still came to school late. A. Having told

B. Having been told

C. Told

D. Being told (3) ____ in thought , he almost ran into the car in front of him.

A. Losing B. Having lost C. Lost D. Being lost 四．分词作状语答题记忆口诀：

分词作状语，主语是问题。

逗号前后两动作，共用一主语。

主语找出后，再来判关系。

主动-ing,被动用-ed。

Having been done 表先后，

千万要牢记。

五巩固练习：

一．单句改错。

1. There have been several new events adding to the program for the 2008 Beijing Olympic Games.

2. Five people won the “China’s Green Figure” award, a title is given to ordinary

people for their contributions to environmental protection. 3. “Things have lost never come again!” I couldn’t help talking to myself.

4. The first textbooks that written for teaching English as a foreign language came out in the 16th century. 5. The players selecting from the whole country are expected to bring us honor in this summer game.

6. The murderer was brought in, with his hands was tied behind his back.

7. Lucy has a great sense of humor and always keeps her colleagues amusing with her stories.

8. Followed some officials, Napoleon inspected his army.

二．用括号内所给动词的恰当形式填空。

1. _______________（compare）with his room, my room is small. 2. _______________ (see) from the mountain, Qingdao looks beautiful at night. 3. ________________ (praise) by the teacher, Lihua made up his mind to study English well. 4. The thief was brought in, with hands _______________ (tie) back. 5. Unless ________________ (invite), I won’t go to the party.
