高考竞争异常激烈，千军万马争过独木桥，秋天到了，而你正以凌厉的步伐迈进这段特别的岁月中。这是一段青涩而又平淡的日子，每个人都隐身于高考，而平淡之中的张力却只有真正的勇士才可以破译。为了助你一臂之力，小编为你精心准备了高三英语知识点分词作状语，助你金榜题名！

难点形成原因:

1.对在句中作时间、条件、原因还是别的状语不是很清楚。

2.分不清何时用现在分词、何时用过去分词。

解决办法：

1.理解分词作状语时可以转换成相应的状语从句。

2.分清何时用现在分词、何时用过去分词。

用法讲解：

1.分词或分词短语作状语时，可以表示时间、原因、让步、条件，方式或伴随状况。通常可转换成相应的状语从句;表示方式或伴随状况时可以转换成并列句或非限制性定语从句。例如：

Putinto use in April 2000 (=When it was put into use in April 2000), the hotlinewas meant for residents reporting water and heating supply breakdowns.分词短语作时间状语

Blamedfor the breakdown of the school computer network (=Because she was blamed forthe breakdown of the school computer network), Alice was in low spirits.分词短语作原因状语

Giventime (=If he is given time), he’ll make a fist-class tennis player.分词短语作条件状语

Weoften provide our children with toys, footballs or basketballs, thinking thatall children like these things. (= and think that all children like thesethings.) 分词短语作伴随状语

2.有时为了强调，分词前可带when, while, if, though, as if,unless等连词一起作状语，以便使句子的意思更清楚、更连贯。例如：

Whencomparing different cultures, we often pay attention only to the differenceswithout noticing the many similarities.

Thoughtired, he still continued reading.

3.现在分词和过去分词作状语时的用法比较。

不管是现在分词还是过去分词单独作状语，其逻辑主语必须与主句的主语一致。分词作状语通常可转换成一个相应的状语从句或并列句，如果状语分句或并列句中的谓语动词为被动结构，就用过去分词;如果状语分句或并列句中的谓语动词为主动结构，就用现在分词。例如：

Whencompared with the size of the whole earth , the biggest ocean does not seem bigat all.

分词部分相当于Whenthe biggest ocean is compared with the size of the whole earth,主语与分词是被动关系，所以用过去分词。

Whencomparing it with the size of the whole earth, we find that the biggest oceandoes not seem big at all.

Whenwe compare it with the size of the whole earth... 主语与分词是主动关系, 所以用现在分词。

Facedwith a bill for$10,000(=Because he is faced with a bill for$10,000), John hastaken an extra job.

Wheneverhe was asked why he was late for class, he would answer carelessly, alwayssaying the same thing (= and he would say the same thing).

注意：

1.现在分词有两种时态：一般式doing和完成式havingdone。一般式通常表示与主句的谓语动词所表示的动作同时发生或无先后;完成式则强调分词所表示的动作先于谓语动词所表示的动作。如：

Whilewalking in the street, we met some friends of ours.(同时发生)

Havingwaited in the queue for half an hour, Tom suddenly realized that he had left hiswallet at home. (“等待”先于谓语动词“意识到”)

2.分词的否定式的构成: not +分词。 Not having received a reply, he decided to write again.
