高考考试角逐异常激烈，千军万马争过独木桥，秋季到了，而你正以凌厉的节奏迈进这段特别的岁月中。这是一段青涩而又平淡的日子，每一个人都隐身于高考考试，而平淡之中的张力却只有真的的勇士才可以破译。为了帮你一臂之力，智学网高中频道为你精心筹备了《高三英语要点必修3、分词作状语》帮你金榜题名！
难题形成缘由:
1. 对在句中作时间、条件、缘由还是别的状语不是非常了解。
2.分不清何时用目前分词、何时用过去分词。
解决方法：
1.理解分词作状语时可以转换成相应的状语从句。
2.分清何时用目前分词、何时用过去分词。
使用方法解说：
1. 分词或分词短语作状语时，可以表示时间、缘由、让步、条件，方法或随着情况。一般可转换成相应的状语从句;表示方法或随着情况时可以转换成并列句或非限制性定语从句。比如：
Put into use in April 2000 , the hotline was meant for residents reporting water and heating supply breakdowns. 分词短语作时间状语
Blamed for the breakdown of the school computer network , Alice was in low spirits. 分词短语作缘由状语
Given time , he’ll make a fist-class tennis player. 分词短语作条件状语
We often provide our children with toys, footballs or basketballs, thinking that all children like these things. 分词短语作随着状语
2. 有时为了强调，分词前可带when, while, if, though, as if, unless等连词一块作状语，以便使句子的意思更了解、更连贯。比如：
When comparing different cultures, we often pay attention only to the differences without noticing the many similarities.
Though tired, he still continued reading.
3. 目前分词和过去分词作状语时的使用方法比较。
无论是目前分词还是过去分词单独作状语，其逻辑主语需要与主句的主语一致。分词作状语一般可转换成一个相应的状语从句或并列句，假如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;假如状语分句或并列句中的谓语动词为主动结构，就用目前分词。比如：
When compared with the size of the whole earth , the biggest ocean does not seem big at all.
分词部分等于When the 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。
When comparing it with the size of the whole earth, we find that the biggest ocean does not seem big at all.
When we compare it with the size of the whole earth... 主语与分词是主动关系, 所以用目前分词。
Faced with a bill for$10,000, John has taken an extra job.
Whenever he was asked why he was late for class, he would answer carelessly, always saying the same thing .
注意：
1. 目前分词有两种时态：一般式doing和完成式having done。一般式一般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：
While walking in the street, we met some friends of ours.
Having waited in the queue for half an hour, Tom suddenly realized that he had left his wallet at home.
2. 分词的否定式的构成: not +分词。 Not having received a reply, he decided to write again.
