5、iately.10. With these words, the speaker（前往） towards the exit of the hall.二.Learning tip分词做状语（单元语法讲解）分词是动词的三种非限定形式之一，分为两种：现在分词和过去分词。现在分词的形式是“动词原形+ing” ；规则的过去分词在动词原形后加“ed”。分词也具有动词的特征，有时态和语态的变化，并可带状语宾语等。分词的否定式在分词前加not （例如：notwhishing, not having received）.分词做状语时表示的动作是主语的一部分，与谓语表示的 动作（或状态）是同时或几乎同时发生的，有

6、时先于谓语的动作发生。分词做状语一般于其他成分用逗号分开。分词可以做时间，原因，方式，条件，结果，目的，让步等状语。由于该语法对高中生做题过程中易出错，特此提出一些做题思路，以备同学们参考：分词（do）形式含义现在分词doing主动，进行being done被动，进行having done主动，完成having been done被动，完成过去分词done1.被动2.完成3被动，完成1.题型结构：, S+V+O.（多把表时间，原因，条件，目的状语等放句前） S+V+O,.（表结果，伴随的状语等放句后）逗号前后没有连词连接（and, but, when, as, where, however,等

7、）,就构成了非谓语做状语的基本前提，现在分词的主动式主要是与句中主语逻辑上的一种主谓关系（），现在分词的被动式主要是与句中主语逻辑上的一种动宾关系；现在分词的进行式是指分词所表 示的动作（或状态）与句中动作同时或几乎同时发生，现在分词的完成式是指分词所表 示的动作（或 状态）一定先于句中谓语动作发生。Eg.1. Seeing from the hilltop, he was delighted to see a wonderful view.主动关系-I-同时关系此句中，逗号前后无连词连接故不能同时出现两个简单句，see逻辑主语是 he,他们之间是一种主谓关系（主动），see动作与be del

8、ighted to see几乎是同时性（同时），因此seeing（主动，进行）符合要求，相当与一个时间状语从句：when he saw fromthe hilltop, he was delightedto see a wonderful view 。1. Seen from the hilltop, the valley looked like a wonderland.（ 从山顶上看去，峡谷宛若 仙境。）在本句中，see与the valley构成了逻辑上的动宾关系即可理解为“峡谷”是被看的，而峡谷的美（宛若仙境）是本身存在的事实，因此用过去分词强调 see与主语the valley的被动关

9、系即可。3. Seen from the pagoda, the south foot of the Purple Mountain is a sea of trees.从这个塔上远眺，紫金山南麓是树的海洋。4. Having written an important letter, I listened to the music for a while.此句中 write与I是逻辑上的主谓关系 （主动），write动作先于句中listen to the music 的动作，故用having written（主动，完成）作状语。5. Having been written in haste,

10、the essay was not worth reading.此句中the essay与 write 是被动关系，whte动作先于 be worth reading之前 是同时强调被动完成，所以选用Having been written（被动，完成）,该分词表原因。为了使同学们更好地理解，特分类如下：1）作时间状语时相当与 when引导的时间状语从句。这类状语通常放在句子的前半部分，也可至于句子后面，若两个动作同时发生，可在分词前用when或while表示强调。Eg. Hearing the news, they immediately set off for Shanghai. （When

11、 they heard the news ,they）When leaving the airport, they waved again and again to us.Having finished his homework, he watched TV for a while.2）作原因状语相当于 as, since, because引导的从句，这类状语多放在句子的前半部 分。Eg: Being a layman in matters of culture, I would like to study them. .（As I am a layman in matters of cult

12、ure, I would like to study them.）The doctor, not wanting to make the patient nervous, did not explain the seriousness of his illness.3）作条件状语相当于if, unless等引导的从句 这类状语一般放在句子的前半部分。Eg: Turning to the right, you will find a path leading to his cottage.（If you turn to the right, you）United we stand, divide

13、d we fall.团结就是胜利，分裂必然失败。4）作让步状语相当于though ,even if等引导的从句。表示让步的状语要放句前，一 般不可放在句尾，但前有连词时例外。Admitting what she has said, I still think that she hasn't tried her best.（A though I admit what she has said, I still think ）尽管承认她所说的话，但我仍然认为她没有尽最大的努力。Granting his honesty, we still can 't employ him.就算他是

14、诚实的，我们也不能雇佣 他。4）作方式或伴随状语不能用状语从句替换，但可以改成并列句，通常放句后。He walked down the hill, singing softly to himself.（He walked down the hill and sang softly to himself.）Kneeling and shutting her eyes, she prayed to the goddess.She stood by the window watching the sunsets.The boy run home , crying5）作结果状语相当于 s。that引导

15、的从句。这类状语通常放在句子的后半部分，并 有逗号同前面的句子成分隔开，长可以译为“于是，所以，或因此”等。这种 分词的逻辑主语即可以是句子的主语，也可以是前边的整个句子，如果逻辑主 语是前边的整个句子，其作用相当于一个非限制性定语从句。Eg: The old scientist died all of a sudden, leaving the project unfinished.He turned off the lamp,（thereby） seeing nothing.The output of steel increased by 15% last year, reaching 3

16、0,000 tons.以上是我们对分词做状语简单了解，但在具体作题中会碰到很多问题，如何准确判断，总结如下：1）有一类题，和分词做状语结构相似，但他是一种独立成分做状语，无需考虑逻 辑主语的主被动关系，动作的完成或同时，所以称之为独立成分，请牢记以下 内容：According to （根据）Judging from/by （由判断）Considering（鉴于）Provided/providing that （如果）Compared to/with（与相比较）Supposing that（假设，如果）Generally speaking 一般说来Frankly speaking 坦白地说Pro

17、perly speaking 正确的说来To tell you the truth 说实话Taking into consideration 考虑至USeeing 考虑到Saving 除了，除非Assuming假使Admitting 虽说，即使Given 如果Eg：Given another chance ,l II do it better.Given time, he 'll make a first class writer.（2003,北京，28）Judging from his accent, he is from the north.Considering your age

18、, you'd better live with your son.Generally speaking, the more expensive the camera, the better its quality.be satisfied with be surprised at be accepted bybe lost in thoughtbe surrounded by2）另一类题是由 be +p.p.+ prep+n/pron/v-ing ,要么是被动语态，要么是表一种 状态，此结构，一般情况去be后，可把分词直接用做状语。be excited about be please
