观察并试着总结状语从句怎样转换成分词作状语。（从句

分词）

1) Seen from the hill top, the valley looks like a wonderland. = When/If the valley is seen from the hill top, it looks like a wonderland.

句中的V-ed短语可以转换成时间或条件状语从句。由此可以断定此V-ed短语在句中作时间/条件状语。

小结：当从句主语和主句主语一致，且从句谓语和主句主语是主动关系时，可以省略状语从句的_____、_____,当谓语中含有be或助动词do时，也应一起省略），再把谓语中的实义动词变成_______，其他不变。

2.请把下列分词作状语转换成状语从句。

Eg: Once published, his work became famous for the absence of rhyme at the end of each line.

=Once his work was published, his work became famous for the absence of rhyme at the end of each line.

①.As soon as translated into English, the book became very popular in the Western World.

______________________________________________________ ②.Connected to the rest of the house by a long passage, the room seems very quiet.

________________________________________________________ ④.The children ran out of the room,laughing merrily.

(______ 状语)

提示：现在分词作伴随状语相当于一个由______连接的并列谓语或并列句。

Part4:主语的一致性

(6mins) 1.从句的主语和主句的主语必须一致。

II. Correct the following sentences. 1. Giving more time, I would do it better.

2. Deeply moving by his words, the old man agreed to his request.

3. Seen his mother coming, the child was very happy.

4. The murderer was brought in, with his hands tying behind his back.

5. He came back with a basket filling with eggs.

提示：

(1).从句的主语和主句的主语必须一致。即v-ed分词作状语时，它的逻辑主语就是整个句子的主语，并表示被动的关系。否则，

(2).分词必须有自己的主语。这种带主语的分词叫做分词的独立结构。在句中作状语，表示时间、条件、原因、结果、让步、伴随或方式。

2.完成句子

①._____________,we`ll do another two exercises.

如果时间允许，我们将做另两个练习。

②.______________,we decided to go swimming.

天气好，我们决定去游泳。
