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, that girl could pass herself off in three months as a duchess at an ambassador’s garden party. P30

Explanation: 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.

Absorbed in deep thought, he didn’t hear the sound. Grown in rich soil, these seeds can grow fast.

The trainer appeared, followed by six little dogs.

He walked up and down the room, lost in thought. When heated, ice can be changed into water. T: Now please look at these examples. Can you rewrite these sentences?Do it! Then check the answers and show the answers to the students. Because he was absorbed in deep thought, he didn’t hear the sound.

Explanation

现在分词与过去分词作状语的区别

1. 逻辑关系: 现在分词作状语与过去分词作状语的最主要区别在于：两者与所修饰的主句的主语的逻辑关系的区别。

1)

现在分词作状语时，现在分词所表示的动作与句子主语之间构成逻辑上的主动关系。

He went out, shutting the door behind him. 他出去后将门随手关上。

Not knowing what to do, he went to his parents for help.

由于不知如何办是好，他去找父母帮忙。

2）

过去分词作状语时，过去分词所表示的动作与句子主语之间构成逻辑上的被动关系。

Given more encouragement, the boy could have behaved better.

如果多给这个孩子一些鼓励，他本来会表现得更好。

Faced with difficulties, we must try to overcome them.

在遇到困难时，我们必须设法克服。

2. 时间概念

过去分词所表示的动作发生在谓语动作之前，或表示“一种状态”，与谓语动作同时发生或存在。现在分词的一般式(doing)表示的动作与谓语动作同时发生或在说话时正在进行；现在分词的完成式(having done)表示发生在谓语动作之前的一个“主动”动作；

Written in a hurry, this article was not so good.

因为写得匆忙，这篇文章不是很好。

Reading carefully, he found something he hadn’t known before.

他仔细读书时，发现了一些从前不知道的东西。

Having finished his homework, he went home.

完成了作业，他就回家了。

现在分词的完成式的被动式(having been done)常和表示次数的短语及时间段(for+一段时间)连用，表示发生在谓语动作之前的一个“被动动作”，这种情况下不能用过去分词替换，其它情况下通常被过去分词所替换，使句式更简洁。

Having been discussed several times, the decision was finally made.

进行了几次讨论后，终于做出了决定。
