状语从句和分词作状语的转换
状语从句与分词作状语的转换时间、原因等状语从句可以转换成分词作状语,但这种转换是有条件的,也有一定的规律可循。
一、基本规则,也是最重要的规则是:从句的主语与主句的主语必须一致,变从句而主句不变。
如:They did not go to the Summer Palace because they had a lot of work to do.由于从句的主语与主句的主语都是they,可以把从句中because和they去掉,把had变成having,即成现在分词短语作原因状语:Having a lot of work to do,they did not go to the Summer Palace.二、从句如果表示主动、完成,进行的动作,则转换成现在分词;如果表示被动,则转换成过去分词。
1.When he heard a cry for help,he rushed out.从句中,he was与heard是主动关系,表示“他听见”。
则可变成现在分词作时间状语。
Hearing a cry for help,he rushed out.2.The boy Cater went up to his teacher and said“sorry”because he was great-ly touched by his words.从句中,he was touched是被动关系,是“孩子被深深地触动了”,则变成过去分词作原因状语。
Greatly touched by his teacher's words,the boy laterwent up to him and said“sorry”.三、如果从句的主语与主句的主语不一致,该怎么办?请看下例:1.As the heroes' deeds moved them deeply,they decided to study even harder.句中,主句的主语是they,而从句主语是the heroes'deeds,主语不一致,这时可以把从句变换一下句型,变成被动语态。

如:After class was over (=Class being over / Class over), the students soon left the classroom.下课后,学生很快离开了教室。
2. 不能省略being (having been)的情形在下列两种情况下,独立主格结构中的being(或having been)不能省略:(1)独立主格结构的逻辑主语是代词时。
如:It being Sunday, we went to church.因为是星期天,我们去了做礼拜。
(2)在There being+名词的结构中。
如:There being no bus, we had to go home on foot.因为没有公共汽车,所以我们不得不步行回家。
3. 通常不用物主代词或冠词在“名词(或代词)+介词短语”构成的独立主格结构中,一般不用形容词性物主代词和冠词。
如:Miss Smith entered the classroom, book in hand.史密斯先生走进了课室,手里拿着一本书。
比较with的复合结构:Miss Smith entered the classroom, with a book in his hand.4. 独立主格结构没有所有格形式The chief-editor arriving, we began the meeting. 主编来了,我们开始开会。
比较动名词复合结构:The chief-editor’s arriving made us very surprised.5. 独立主格的时态问题独立主格结构作时间或原因状语时,可用完成时,表示该动作发生在谓语之前。
