Dangling participle
1. “attachment rule” and “dangling participle”
2. problems about the acceptability of “dangling participles”
attachment rule” and “dangling participle”
When an –ing or –ed participle construction is used as a relative or adverbial clause， its logical subject is usually identifiable with the subject or other element of the main clause. It is through this relationship that the participle construction is “attached” to the main clause. This is known as the “attachment rule”.
attachment rule” and “dangling participle”
e.g. Sitting at the back as we were， we couldn’t hear a word.
He was hurt by a stone dropped from the roof.
Violation of the “attachment rule” will result in a “dangling participle”
e.g. Opening the cupboard， a skeleton fell out.
Being dark， we had to go back.
problems about the acceptability of “dangling participles”
Linguists are divided in opinion about the acceptability of “dangling participles”. Prescriptive grammarians condemn all “dangling” consructions， while descriptive linguists take a more liberal point of view. “Dangling” constructions should not be regarded as objectionable indescriminately.
problems about the acceptability of “dangling participles”
These constructions are frequently found in formal scientific writing， in which it is general practice to avoid using personal subjects. In formal style， so long as they do not cause ambiguity or confusion in meaning， “dangling participles” should also be viewed as normal and acceptable.
problems about the acceptability of “dangling participles”
Only “dangling” constructions are objectionable or unacceptable that cause ambiguity or suggest aburd interpretations. Form pedagogical point of view， however， beginners in English should not be encouraged to use “dangling” constructions unless in scientific writing.
problems about the acceptability of “dangling participles”
Now assess the following:
When installing a boiler， the floor space which is available is very important.
Using the electricity energy， it is necessary to change its form.
Having been deserted by his guide， there seemed little hope that the explorer would find his way through the jungle.
problems about the acceptability of “dangling participles”
Now assess the following:
When driving carelessly， it is easy to have an accident.
Standing on the church tower， the whole village could be seen.
Having eaten our lunch， the car pushed its way through the tortuous canyon.
Conclusion on participle
分词作定语相当于定语从句，如Most of the people invited to the party were famous scientists. = Most of the people who wereinvited to the party were famous scientists.
典型例题
1） The first textbook ___ for teaching English as a foreign language came out in the 16th century.
A. have written B. to be written C. being written D. written
答案D. 书与写作是被动关系，应用过去分词做定语表被动，相当于定语从句 which was written
Conclusion on participle
2）What's the language ____ in Germany?
A. speaking B. spoken C. be spoken D. to speak
答案B. 主语language与谓语动词之间有被动的含义。spoken，在句中作定语，修饰主语language， spoken 与 language有被动关系。该句可以理解为：What's the language （which is） spoken in German?
Conclusion on participle
分词作状语，可以表示时间，原因，理由，条件，让步，连续等，相当于一个状语从句。例如：
Not receiving any letter from him， I gave him a call. 由于没有收到他的信，我给他打了个电话。
As I didn't receive any letter from him， I gave him a call.
Given more attention，the trees could have grown better. 多给些照顾，那些树会长得更好。
If more attention was given， the trees could have grown better.
Conclusion on participle
典型例题
1）_____ some officials， Napoleon inspected his army.
A. Followed B. Followed by C. Being followed D. Having been followed
答案B. Napoleon 与follow 之间有被动的含义。being followed除表达被动之外，还有动作正在进行之意。 followed by（被…跟随）。本题可改为： With some officials following， Napoleon inspected his army.
Conclusion on participle
典型例题
2）There was a terrible noise ___ the sudden burst of light.
A. followed B. following C. to be followed D. being followed
答案B. 由于声音在闪电后，因此为声跟随着光，声音为跟随的发出者，为主动。用现在分词。
Conclusion on participle
典型例题
3）_______， liquids can be changed into gases.
A. Heating B. To be heated C. Heated D. Heat
答案C. 本题要选分词作为状语。现在分词表主动，正在进行的；过去分词表被动的，已经完成的。对于液体来说是加热的受动者，是被动的，因而选C。它相当于一个状语从句 When it is heated，…
Conclusion on participle
注意：选择现在分词还是过去分词，关键看主句的主语。如分词的动作是主句的主语发出，分词就选用现在分词，反之就用过去分词。例如：
Used for a long time， the book looks old. 由于用了很长时间，这本书看上去很旧。
Using the book， I find it useful. 在使用的过程中，我发现这本书很有用。
Conclusion on participle
连词+分词（短语）
有时为使分词短语与主句关系更清楚，可在分词前加连词。 连词有： when，while，if though，after， before， as. 但分词的主语和主句的主语必须为同一个。例如：
While waiting there， he saw two pretty girls come out of the building.
等在那儿时，他看见两个靓妹走出大楼。（waiting 和saw 的主语相同）
Conclusion on participle
分词作插入语
分词作插入语的结构是固定的，意思上的主语并不是句子的主语。例如：
generally speaking 一般说来
talking of （speaking of） 说道
strictly speaking 严格的说
judging from 从…判断
all things considered 从整体来看
taking all things into consideration 全面看来
Conclusion on participle
例如：Judging from his face， he must be ill. 从他的脸色看，他一定是病了。
Generally speaking， dogs can run faster than pigs. 总的来说，狗比猪跑得快。 （speaking 不是dogs 的动作）
Conclusion on participle
独立主格
独立主格结构的构成：名词（代词）+现在分词、过去分词；
名词（代词）+形容词；
名词（代词）+副词；
名词（代词）+不定式；
名词（代词） +介词短语构成。
Conclusion on participle
独立主格
独立主格结构的特点：1）独立主格结构的逻辑主语与句子的主语不同，它独立存在。
2）名词或代词与后面的分词，形容词，副词，不定式，介词等是主谓关系。
3）独立主格结构一般有逗号与主句分开。
Conclusion on participle
独立主格
The test finished， we began our holiday. = When the test was finished， we began our holiday. 考试结束了，我们开始放假。
The president assassinated， the whole country was in deep sorrow. = After the president was assassinated， the whole country was in deep sorrow. 总统被谋杀了，举国上下沉浸在悲哀之中。
Weather permitting， we are going to visit you tomorrow. 天气允许，我们明天去看你。
This done， we went home. 工作完成后，我们才回家。
Conclusion on participle
独立主格
The meeting gone over， everyone tired to go home earlier. 会议结束后，每个人都想早点回家。
He came into the room， his ears red with cold. 他回到了房子里，耳朵冻得红通通的。
He came out of the library， a large book under his arm. 他夹着本厚书，走出了图书馆
Conclusion on participle
with的复合结构作独立主格
表示伴随情况时，既可用分词的独立结构，也可用with的复合结构：with +名词（代词）+现在分词/过去分词/形容词/副词/不定式/介词短语。例如：
He stood there， his hand raised. = He stood there， with his hand raise.他举手着站在那儿。
Conclusion on participle
with的复合结构作独立主格
典型例题
The murderer was brought in， with his hands ___ behind his back。
A. being tied B. having tied C. to be tied D. tied
答案D. with +名词（代词）+分词+介词短语结构。当分词表示伴随状况时，其主语常常用with来引导。由于本句中名词"手"与分词"绑"是被动关系，因此用过去分词，选D.
注意:
Conclusion on participle
1） 独立主格结构使用介词的问题： 当介词是in时，其前后的两个名词均不加任何成分（如物主代词或冠词），也不用复数。但 with 的复合结构不受此限制。例如：A robber burst into the room， knife in hand.（hand前不能加his）劫匪冲进房间，手里拿着刀。
Conclusion on participle
2） 当表示人体部位的词做逻辑主语时，及物动词用现在分词，不及物动词用过去分词。例如：
He lay there， his teeth set， his hand clenched， his eyes looking straight up.
他躺在那儿，牙紧咬，双手握拳，两眼直勾勾看着上面。
Conclusion on participle
典型例题：
Weather___， we'll go out for a walk.
A permitted B permitting C permits D for permitting
答案B. 本题中没有连词，它不是复合句，也不是并列句。 句中使用了逗号，且we 小写，可知其不是两个简单句。能够这样使用的只有独立主格或with的复合结构。据此判断，本句中使用的是独立结构，其结构为：名词+分词。 由于permit在这里翻译为'天气允许'，表主动，应用现在分词，故选B。
如果不会判断独立结构作状语的形式，不妨将句子改为条件句，例如本句改为If weather permits， we'll go out for a walk. 然后将if 去掉，再将谓语动词改为非谓语动词即可。
分词与从句的转换
1．分词作修饰语转化为关系从句
由于分词作修饰语与被修饰语存在逻辑关系（主谓或者动宾），即被修饰语为关系分句的主语。找关系从句的主语。
确定语态：现在分词用主动，过去分词用被动。
确定时体：现在分词表示正在进行的动作，用进行体；
表示经常、习惯性动作，用一般体
确定与主句动词一致的时。
分词与从句的转换
4）确定关系词：
There are a number of students waiting to get examined.
---There are a number of students who are waiting to be examined.
What do you think of the performance given by the girls of Grade III?
---What do you think of the performance that was given by the girls of Grade III.
分词与从句的转换
2．关系从句转化为分词
1）确定用现在分词还是过去分词：关系分句为主动句，用现在分词
关系分句为被动句，用过去分词
2）确定分词的时体：根据从句动词与主句动词的时间关系。
从句动词发生在主句动词在之前，用完成体；从句动词与主句动词同时或几乎同时发生，用一般体。
Any driver who does not have a licence should be sent to jail.
Any article that is left in the bus will be taken at once to the lost property office.
分词与从句的转换
3．分词转化为状语从句
确定连词：根据分词的语法作用确定
确定主语：根据分词逻辑主语
确定语态：现在分词―――主动；过去分词――被动
确定时态：根据意义和主句动词与分词发生的时间关系
确定主谓一致性
分词与从句的转换
4．状语从句转化为分词
确定用现在分词还是用过去分词：
确定时体：从句动作在主句动作之前发生，用完成体；
从句动作与主句动作同时发生，用完成体
3) 如果逻辑主语与句子主语不一致时，用独立主格结构.
分词与从句的转换
4．状语从句转化为分词
确定用现在分词还是用过去分词：
确定时体：从句动作在主句动作之前发生，用完成体；
从句动作与主句动作同时发生，用完成体
3) 如果逻辑主语与句子主语不一致时，用独立主格结构.
