①现在分词短语在句中作状语，可以表示伴随、结果，相当于一个并列句，因此可以和and连接的并列句转换，也可和with复合结构转换。

He went out，leaving the lights on.(结果) ＝He went out，with the lights on. ＝He went out and left the lights on. 他出去了，灯开着。

He lay in bed，reading a novel.(伴随) ＝He lay in bed and read a novel. 他躺在床上读小说。

②现在分词短语在句中作状语还可以表示时间、原因、条件、让步等。其结构相当于一个状语从句。

Finishing the work，he left his office.(时间) ＝After he finished the work，he left his office. 工作完成之后他离开了办公室。

Not knowing the answer，he kept silent.(原因)

＝Because he didn't know the answer，he kept silent. 因为不知道答案，他保持沉默。

Working hard at your lessons，you'll succeed.(条件) ＝If you work hard at your lessons，you'll succeed. 如果你努力学习，就一定能成功。 Working hard as he did，he was still unable to earn enough money to buy a car.(让步)

＝Though he worked hard as he did，he was still unable to earn enough money to buy a car.

他虽然努力地工作，但仍然挣不到足够的钱来买辆车。 ③过去分词短语也可以在句中作状语。

Given enough time，we could have done it better. 如果时间再足够一些，我们还能够做得更好。

The teacher went out，followed by his students. 老师出发了，后面跟着他的学生们。 ●误区警示

(1)分词作状语时，必须遵循下列基本原则： ①分词的逻辑主语必须与句子的主语保持一致。

②分词作状语必须和句中主语含有逻辑上的主谓或动宾关系。 (2)过去分词和现在分词的完成式不能作主语。 即境活用 单项填空

①No matter when she is asked why she is often late for school，she will answer carelessly，always________the same thing.

A．to say B．says

C．saying D．having said

②________things down，he began to think over the next subject. A．Settling B．Having settled C．Settled D．To settle

答案：①C 此处现在分词作状语，因为she与say为逻辑上的主谓关系，所以用现在分词。而having done表示动作发生在谓语动词之前。

②B 句意为：把事情安顿好之后，他开始考虑下一个课题。settle的逻辑主语与主句主语一致且发生在主句谓语动词之前，故用settle的现在分词的完成形式，表示动作发生在主句谓语动词之前，故选B。

5．The thought that they could cross the whole continent was exciting. 要横贯整个大陆的想法很是令人兴奋。 ●用法拓展

该句中that they could cross the whole continent是引导词that引导的同位语从句，作the thought的同位语，表示对thought的进一步说明或解释，其中引导词that不可以省略。同位语从句所说明的先行词通常是抽象名词，如fact，news，hope，belief，idea，question等。从句最常用的引导词是that，还有其他词也可以充当，如：从属连词whether，关系代词what，who等，关系副词how，when，why等。如：

I didn't find the answer to the question whether he would join us or not. 我没有找到他是否加入到我们中间这个问题的答案。

I don't have any idea what you will do with this problem. 我不知道你将如何处理这个问题。

It is still a problem how we persuade him to give up. 我们如何说服他放弃一直是一个问题。

同位语从句和定语从句看上去很相似，而这两类从句各自的特点是：(1)定语从句对先行词起修饰、限制作用；同位语从句具体说明它前面的名词的内容。(2)that在定语从句中担任句子成分，是关系代词。当that在从句中充当宾语时可以省略；that在同位语从句中不担任句子成分，是从属连词，通常不省略。如：

The news that you told me was not true. 你告诉我的消息不真实。(定语从句)

The news that our team won the gold medal excited us. 我们队赢得了金牌这个消息使我们很兴奋。(同位语从句) 即境活用 单项填空

6．It is so wet there that the trees are extremely tall, some measuring over 90 metres.

那儿的湿度很大，所以树都长得特别高，有一些高达90米。 ●用法拓展

some measuring over 90 metres该结构称作独立主格结构。独立主格结构是由名词或代词加上分词或分词短语组成的一种独立结构，用于修饰整个句子，而不是词或词组。独立主格结构中的名词或代词与其后的分词构成主谓关系。这种结构与其主句不发生句法上的联系，并且位置灵活，可置于主句前、主句后或主句中，用逗号隔开。如：

He lay at full length on his stomach, his head resting up on his left forearm. 他脊背朝天，四肢伸展，头枕着左前臂，直挺挺的趴着。 There being a heavy rain, he went back home hurriedly. 要下大雨了，他急忙回家。 即境活用 翻译句子
