1、句子结构常见错误 盛年不重来，一日难再晨。及时宜自勉，岁月不待人。句子结构常见错误Sentence Structure Problems英语句子是受严格的语法规则制约的，在写作中如果违背这些规则，那么写出的句子就会使人无法理解，或引起歧义。要想避免发生这些情况，在写作时就必须处理好句子结构方面的几个问题。我们对常犯的写作错误进行了归纳。残缺句、接排句、误置修饰语和悬垂修饰语是句子结构中最常见的错误。我将对这些问题逐一进行分析，以帮助大家弄清写作中出现这些问题的原因，并掌握纠正错误的方法残缺句(Sentence Fragments)所谓残缺句，顾名思义，就是指不能独立成句的一个不完整的句子片断。

2、尽管残缺句在形式上像句子一样是以大写字母开头，并在结尾处带有标点，然而在逻辑上并不能单独表达一个完整的意思,仅是一组词而已。请看下列句子：Fragment Wondering what his son was going to doRevised Sentence MrSmith had been wondering what his son was going to doFragment Some errors in writing are seriousFor example， fragments and runon sentencesRevised Sentences Some erro

3、rs in writing are serious，for example， fragments and runon sentencesOR Some errors in writing are serious，among which are fragments and run-on sentences虽然句子的残缺以各种形式出现，但最常见的形式是被分隔开的从句和以各种形式拆开的短语，如句号错误(period fault)。Fragments Having driven across the desertWe enjoyed the cool weather He enjoys flowers

4、 and shrubsWhich help screen his yard from the streetRevised Sentences Having driven across the desert， we enjoyed the cool weather He enjoys flowers and shrubs，which help screen his yard from the street0R He enjoys flowers and shrubsThey help screen his yard from the street在写作中要经常检查句子的残缺问题，特别要注意那些以

5、从属连词或短语等开头的句子，这些词都是“危险词”。要确定以这些词开始的每个从句，都应附属于一个独立的句子。 避免残缺句的最好办法是注意区别句子和句子的一部分。我们知道句子的最基本特点是在语法和逻辑上是一个完整的意义表达单位。它至少具有一个主语和谓语。动词的非限定形式不能在句中作为谓语单独使用，除非是在如Where to go tonight?简短的问句中。因此在写句子时要特别注意。改写残缺句主要有以下两种方法： 1将句中用的句号变成逗号，或把分隔开的短语或从句同它所属 的句子合并成一个能表达完整意思的句子。例如：FragmentsSince there is a lack of interes

6、tThere is a great lack of information You should make a determined effort to avoid sentence fragmentsBecause they are considered serious mistakes in writing I look forward to holidaysFor example, Thanksgiving andChristmasRevised Sentences Since there is a lack of interest，there is a great lack of in

7、formation.You should make a determined effort to avoid sentence fragments because they are considered serious mistakes in writing I look forward to holidays，for example，Thanksgiving and Christmas2）把残缺句扩展到主句中，或通过添加或减少某些成分。把残缺 改写为独立、完整的句子。例如：Fragments I am interested only in the properties of citrus f

13、个或更多的句子混合交织在一起，而没有正确的标点符号标明它们之间关系的句子。这样的句子，意思含混不清，使读者不能理解各部分之间的关系。接排句有两种形式:一是融合句(fused sentence)，即在句子之间没有标点符号和句间连接词；另一种更为常见的形式是逗号连接(comma splice)，即没有并列连词，只用逗号代替分号和句号，把两个完整的意思连接起来.请看例句:Fused Sentences 1. The girls scored higher in math the boys scored higher in verbal skills2. Gestures are a means of

14、 communication for everyone they are essential for the hearing-impairedComma Splices 1. Education is an elusive word, it often means different things to different people2.

15、的基本方法可根据句子之间的不同关系分为以下5种1.用句号分隔。当长句或两个句子之间的关系不是很密切或毫无 关系时，可使用这种方法。例如：Revised Sentences The girls scored higher in mathThe boys scored higher in verbal skillsGestures are a means of communication for everyoneThey are essential for the hearing-impaired Education is an elusive wordIt often means differe

16、nt things to different people Hikers would especially enjoy a vacation at Yellowstone NationalParkThe park consists of two million acres of backcountry2 用分号隔开。用分号连接两个独立的分句时，它们之间的关系 在意义和语法结构上比起使用句号时，关系较紧密。Revised Sentences The girls scored higher in math；the boys scored higher inverbal skills Gesture

17、s are a means of communication for everyone；theyare essential for the hearingimpaired Education is an elusive word；it often means different thingsto different people Hikers would especially enjoy a vacation at Yellowstone National Park；the park consists of two million acres of backcountry3使用并列连词连接。当

18、接排的句子之间关系紧密，容易辨别且 合乎逻辑时，可以借助并列连词来连接，通常在这些连词前要 加上逗号。Revised Sentences The girls scored higher in math，andbut the boys scoredhigher in verbal skills Gestures are a means of communication for everyone， butthey are essential for the hearingimpaired Education is an elusive word，for it often means differe

19、ntthings to different people Yellowstone National Park consists of two million acres ofbackcountry，and hikers would especially enjoy a vacationthere4使用连接副词连接。根据作者的意图和句子的需要。接排的句 子可以使用连接副词来连接。这时，句子之间要用分号。在连接副词的后面还要加逗号，但是一般在单音节的连词后不加逗 号。如so，yet。thus等.Revised Sentences The girls scored higher in math；ho

21、f backcountry; therefore, hikers would especially enjoy a vacation there5.使用从属连词、关系副词或关系代词连接. 当可以判断出一个句子从逻辑上或意义上从属于另一个句子时, 可以将此接排句 改写成复合句。Revised SentencesThe girls scored higher in math，while the boys scored higherin verbal skillsAlthough gestures are a means of communication for everyone，they are
