所謂垂懸結構(The Dangling Construction)就是一個句子成分，如分詞短語，不定式動詞短語等，找不到被修飾的主語或被修飾的對象不合邏輯。垂懸結構是種錯誤的句法，應該避免。
下面是三種常見的垂懸結構及其改正方法：
⒈垂懸分詞或分詞短語，如：
①Climbing up the hill, several boars were seen.
這句子里的現在分詞短語(present participial phrase)修飾主語“several boars”是錯的;改正方法有二：
(a)確定是邏輯主語，使句子變成“Climbing up the hill, the explorers saw several boars.”
(b)把現在分詞短語擴大為副詞分句(也稱狀語從句)：“When the explorers climbed up the hill, they saw several boars/ several boars were seen.”
⒉垂懸副詞短語，如：
After putting a shrimp on the hook, the fish began to bite.
這句的副詞短語(adverb phrase)和主語“the fish”有什么邏輯關系呢?真正的邏輯主語應該是“the fisherman”或“the angler”才對。改正方法：
(a) After putting a shrimp on the hook, the fisherman found that the fish began to bite.
(b) After the fisherman had put a shrimp on the hook, the fish began to bite.
⒊垂懸不定式動詞短語，如：
To write well, a lot of practice is needed.
To be a loyal employee, a sense of belonging is a must.
這兩個句子的不定式動詞短語(infinitive phrases)并不能修飾“practice”和“a sense of belonging”，真正的主語必須是“ 人”，如：
(a) To write well, one needs a lot of practice/a person has to practise a lot.
(b) To be a loyal employee, he or she must have a sense of belonging.
上述三類垂懸結構中，第一類發(fā)生的頻率，必須注意。但是在下列三種情況下，分詞短語是對的，它們并非垂懸結構：
第一，獨立結構(The Absolute Construction，見3月7日《中英合談》)中的分詞短語有自己的主語，所以不是垂懸結構。例如：
Such being the case, we can go home now./……it is not wrong to call it a day.
第二，當分詞含有介詞或連詞性質時，它不需要邏輯主語，所以沒有垂懸問題存在。例如：
Owing to a lack of funds, the project has to be discontinued.
Provided that there is sufficient time, everyone can do the job better.
第三，當分詞短語是用來表示說話者的態(tài)度或意見時，也不需要邏輯主語，因此也不存在著垂懸問題。例如：
Judging from his facial look, the news must have been terrible.
Taken as a whole, there is nothing wrong with the logic behind that idea.

連詞及其用法
1.連詞是一種虛詞，它不能獨立擔任句子成分而只起連接詞與詞，短語與短語以及句與句的作用。
2.常見的連詞
and(和，與;而且;于是，然后;因此)
but(但是;通常用not...but...不是...而是...;可是,然而;表示驚訝，不同意等--喔，哇;用來加強語句重復部分的語氣--一定;用來引入新話題--那就;常用于否定句--而不，若不;用于含doubt,question等字的否定句中相當于that--對于)
or(或者，還是;用于否定句或問句--也不;否則，要不然;也就是說，換言之)
nor(用在neither之后--也不;用在no,not,never之后--也不;用在句首，句子需倒裝--也不)
so(因此，所以;因而，從而)
yet(可是，卻，然而)
for(因為，由于)
both…and(既...又...;不但...而且)
not only…but also(不但，而且)
either…or(不是...就是;要么...要么)
neither…nor(既不...也不...)
3.并列連詞：
①and 與or;②both …and兩者都;③not only…but ...as well as=not only...but also不但…而且;④neither…nor意思為"既不……也不……"謂語動詞采用就近原則，與nor后的詞保持一致。
4.轉折或對比連詞
①but表示轉折，while表示對比。②not…but…意思為"不是……而是……"。
賓語從句
1.賓語從句，是名詞性從句的一種。在主從復合句中充當賓語，位于及物動詞、介詞或復合謂語之后的從句稱為賓語從句。賓語從句分為三類：動詞的賓語從句，介詞的賓語從句和形容詞的賓語從句。
2.賓語從句的引導詞有三種：
(1)以that引導的賓語從句：
that引導的賓語從句一般都是由陳述句充當，引導詞that沒有實際意義，不在從句中作任何成分，that可以省略，而且從句成分齊全，句意完整。
Do you think (that) it will rain? 你認為天會下雨嗎?
He said (that) he could come on time. 他說他會準時來的。
(2)以whether或if引導的賓語從句：
從屬連詞if,whether引導的名詞從句是由一般疑問句或選擇疑問句轉化而來的，變成從句后，語序由原來的倒裝語序變成陳述語序。whether和if意為“是否”。
Let us know whether / if you can finish the work before Friday.
請讓我們知道你是否能在星期五以前把工作做完。
I don’t care whether you like the story or not.
我不在乎你是否喜歡這個故事。
(3)特殊疑問詞what/ when/ where/ who等引導的賓語從句：
此類賓語從句原來是特殊疑問句，變成賓語從句后要用陳述語序，由wh-開頭的疑問詞引導。包括who, whom, whose, what, which等連接代詞和where, when, how, why等連接副詞，這些引導詞有各自的意思，在從句中要作相應的成分，不能省略。例如：
Could you tell me which gate we have to go to?
請問我們得走哪個門?
He didn’t tell me how long he would stay here.
他沒有告訴我他要在這里呆多長時間。
九年級上學期英語課文知識點歸納
疑問詞是疑問代詞“who, whom, what, which, whose”和疑問副詞“when, where, how, why ”。此外，連接詞“whether”也適用。
“疑問詞+不定式動詞”結構有何功用呢?其主要功用有下列五種：
⑴當主語，如：
When to hold the meeting has not yet been decided.
Where to live is a problem.
How to cope with the rising cost of living becomes a daily discussion topic.
⑵當賓語，如：
We must know what to say at a meeting.
He could not tell whom to trust.
Do you know how to play bridge?
⑶當補足語，如：
The problem is where to find the financial aid.
The question is who to elect.
⑷當名詞同位語，如：
Tom had no idea which book to read first.
Do you have a rough impression how to do it?
⑸當賓語補足語，如：
Jim is not sure whose to choose.
Mary and John are not certain whether to get married or not.
適用于“疑問詞+不定式動詞”的動詞包括：“know, see, decide, tell, ask, consider, discover, explain, forget, guess, hear, imagine, inquire, learn, remember, think, wonder, understand”等。
有點值得特別注意的是：當這結構當賓語時，它的作用等于名詞分句，例如：
I could not decide which dictonary to buy. / I could not decide which dictionary I should buy.
Jack did not know where to find such a good teacher./ Jack did not know where he could find such a good teacher.
有些動詞，如“ask, show, tell, advise, inform, teach”等，可以先有個賓語，然后才接著加上適當的“疑問詞+不定式動詞” 結構。例如：
The chief technician showed the apprentice how to repair the machine.
Have you told him where to get the application form?
