所谓垂悬结构(The Dangling Construction)就是一个句子成分，如分词短语，不定式动词短语等，找不到被修饰的主语或被修饰的对象不合逻辑。垂悬结构是种错误的句法，应该避免。
下面是三种常见的垂悬结构及其改正方法：
⒈垂悬分词或分词短语，如：
①Climbing up the hill, several boars were
这句子里的现在分词短语(present participial phrase)修饰主语“several boars”是错的;改正方法有二：
(a)确定是逻辑主语，使句子变成“Climbing up the hill, the explorers saw several ”
(b)把现在分词短语扩大为副词分句(也称状语从句)：“When the explorers climbed up the hill, they saw several boars/ several boars were ”
⒉垂悬副词短语，如：
After putting a shrimp on the hook, the fish began to
这句的副词短语(adverb phrase)和主语“the fish”有什么逻辑关系呢?真正的逻辑主语应该是“the fisherman”或“the angler”才对。改正方法：
(a) After putting a shrimp on the hook, the fisherman found that the fish began to
(b) After the fisherman had put a shrimp on the hook, the fish began to
⒊垂悬不定式动词短语，如：
To write well, a lot of practice is
To be a loyal employee, a sense of belonging is a
这两个句子的不定式动词短语(infinitive phrases)并不能修饰“practice”和“a sense of belonging”，真正的主语必须是“ 人”，如：
(a) To write well, one needs a lot of practice/a person has to practise a
(b) To be a loyal employee, he or she must have a sense of
上述三类垂悬结构中，第一类发生的频率，必须注意。但是在下列三种情况下，分词短语是对的，它们并非垂悬结构：
第一，独立结构(The Absolute Construction，见3月7日《中英合谈》)中的分词短语有自己的主语，所以不是垂悬结构。例如：
Such being the case, we can go home ……it is not wrong to call it a
第二，当分词含有介词或连词性质时，它不需要逻辑主语，所以没有垂悬问题存在。例如：
Owing to a lack of funds, the project has to be
Provided that there is sufficient time, everyone can do the job
第三，当分词短语是用来表示说话者的态度或意见时，也不需要逻辑主语，因此也不存在着垂悬问题。例如：
Judging from his facial look, the news must have been
Taken as a whole, there is nothing wrong with the logic behind that
动词不定式
一. 定义：
由to+动词原形构成。不定式是一种非限定性动词。而非限定动词是指那些在句中不能单独充当谓语的动词，可分为不定式，动名词，现在分词和过去分词。“动词不定式”由动词+不定式构成。动词不定式在句中可以作句子除谓语之外的任何句子成分。动词不定式的被动形式除了一般形式外还有其完成式和进行式。
二. 动词不定式的构成：to+动词原形
(1)作主语
动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种： (1)把不定式置于句首。
如：To get there by bike will take us half an
(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。
如：
It+be+名词+to do It's our duty to take good care of the
It takes sb+some time+to do How long did it take you to finish the work?
It+be+形容词+for sb+to do It is difficult for us to finish writing the composition in a quarter of an
It+be+形容词+of sb+to do It is stupid of you to write down everything (that) the teacher
It seems(appears)+形容词+to do It seemed impossible to save
在句型中，常用表示客观情况的形容词，如：difficult，easy，hard，important，impossible，necessary 等;
在句型中，常用careless，clever，good，foolish，honest，kind，lazy，nice，right，silly，stupid，wise等 表示赞扬或批评的词。
在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is+形容词+to do句式 ，如：It's kind of you to help me with my are kind to helpme with my
(3)举例
(1) It's easy (for me) to do 我做这事太容易了
easy,difficult,hard,important,possible,impossible,comfortable,necessary,better;
the first,the next,the last,the best,too much,too little,not enough
1、It's so nice to hear your
听到你的声音真高兴。
2、It's necessary for you to lock the car when you do not use
当你不用车的时候，锁车是有必要的。
(2) It's very kind of him to help 他帮助我们，他真好。
Kind,nice,stupid,rude,clever,foolish,thoughtful,thoughtless,brave,considerate(考虑周到的),silly,selfish(自私的)
例句:
1、It was silly of us to believe 我们真愚蠢，竟然相信了他。
2、It seemed selfish of him not to give them 他不给他们任何东西，这显得太自私了。
注意：
(1) 其他系动词如，look，appear等也可用于此句型
(2) 不定式作为句子成分时，动词用单数形式。
(3) 当不定式作主语的句子中又有一个不定式作表语时，不能用It is… to…的句型
(对)To see is to 眼见为实。
(错)It is to believe to
三. 动词不定式作宾语
后面能接不定式作宾语的动词有：agree, ask, choose, decide, forget, hope, learn, want, wish, would like等。
1、We hope to get there before 我们希望天黑以前到那儿。
2、The man decided to do it 那个男人决定自己做那件事。
动词不定式作宾语的注意事项(2点)
有些动词既可跟不定式作宾语，也可跟动名词作宾语，但含义不同：
remember to do 记住要做某事
remember doing 记得曾经做过某事
forget to do忘记要做某事
forget doing 忘记曾经做过某事
stop to do 停下来去做某事
stop doing 停止做某事
go on to do 继续做另一件事
go on doing 继续做原来在做的事
不定式作宾语时，如带有宾语补足语，则要把不定式放到后面，用it作形式宾语，构成“主语+动词+it+宾补(形容词、名词)+不定式”结构。
如：He found it very difficult to get to 他发现很难入睡。
in : 在旅馆的登记入住。 Check out: 在旅馆结账离开。

②在…旁边。例：by the window/the door

连词及其用法
连词是一种虚词，它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。
常见的连词
and(和，与;而且;于是，然后;因此)
but(但是;通常用不是而是;可是,然而;表示惊讶，不同意等--喔，哇;用来加强语句重复部分的语气--一定;用来引入新话题--那就;常用于否定句--而不，若不;用于含doubt,question等字的否定句中相当于that--对于)
or(或者，还是;用于否定句或问句--也不;否则，要不然;也就是说，换言之)
nor(用在neither之后--也不;用在no,not,never之后--也不;用在句首，句子需倒装--也不)
so(因此，所以;因而，从而)
yet(可是，却，然而)
for(因为，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)
并列连词：
①and 与or;②both …and两者都;③not only…but well as=not also不但…而且;④neither…nor意思为"既不……也不……"谓语动词采用就近原则，与nor后的词保持一致。
转折或对比连词
①but表示转折，while表示对比。②not…but…意思为"不是……而是……"。
宾语从句
宾语从句，是名词性从句的一种。在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。
宾语从句的引导词有三种：
(1)以that引导的宾语从句：
that引导的宾语从句一般都是由陈述句充当，引导词that没有实际意义，不在从句中作任何成分，that可以省略，而且从句成分齐全，句意完整。
Do you think (that) it will rain? 你认为天会下雨吗?
He said (that) he could come on 他说他会准时来的。
(2)以whether或if引导的宾语从句：
从属连词if,whether引导的名词从句是由一般疑问句或选择疑问句转化而来的，变成从句后，语序由原来的倒装语序变成陈述语序。whether和if意为“是否”。
Let us know whether / if you can finish the work before
请让我们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
我不在乎你是否喜欢这个故事。
(3)特殊疑问词what/ when/ where/ who等引导的宾语从句：
此类宾语从句原来是特殊疑问句，变成宾语从句后要用陈述语序，由wh-开头的疑问词引导。包括who, whom, whose, what, which等连接代词和where, when, how, why等连接副词，这些引导词有各自的意思，在从句中要作相应的成分，不能省略。例如：
Could you tell me which gate we have to go to?
请问我们得走哪个门?
He didn’t tell me how long he would stay
他没有告诉我他要在这里呆多长时间。
疑问词是疑问代词“who, whom, what, which, whose”和疑问副词“when, where, how, why ”。此外，连接词“whether”也适用。
“疑问词+不定式动词”结构有何功用呢?其主要功用有下列五种：
⑴当主语，如：
When to hold the meeting has not yet been
Where to live is a
How to cope with the rising cost of living becomes a daily discussion
⑵当宾语，如：
We must know what to say at a
He could not tell whom to
Do you know how to play bridge?
⑶当补足语，如：
The problem is where to find the financial
The question is who to
⑷当名词同位语，如：
Tom had no idea which book to read
Do you have a rough impression how to do it?
⑸当宾语补足语，如：
Jim is not sure whose to
Mary and John are not certain whether to get married or
适用于“疑问词+不定式动词”的动词包括：“know, see, decide, tell, ask, consider, discover, explain, forget, guess, hear, imagine, inquire, learn, remember, think, wonder, understand”等。
有点值得特别注意的是：当这结构当宾语时，它的作用等于名词分句，例如：
I could not decide which dictonary to / I could not decide which dictionary I should
Jack did not know where to find such a good Jack did not know where he could find such a good
有些动词，如“ask, show, tell, advise, inform, teach”等，可以先有个宾语，然后才接着加上适当的“疑问词+不定式动词” 结构。例如：
The chief technician showed the apprentice how to repair the
Have you told him where to get the application form?
【微语】在白开水一样淡的日子里，多放两勺糖。
