英语句子结构的连贯性
英语句子结构的连贯性是指一个句子应表达一个完整的意思,每个分句必须言之有序,不能出现歧义.英语句子的连贯性从结构上看大体可以分为：句内、句间、上下文段落间.句子连贯性实现的重要方式是连接词.句内：连接词( and,because,for等介词,v+ ed\ v+ing的分语修饰词等)；句间：连接词,通常用来表达转折（but,however,conversely等）、递进(more fundamentally,what-s more important)、比较等；段落间：文章结构性（总分,顺序等,也常有连接词）.
要保持句子结构的连贯性,必须做到以下五个一致：
l 时态一致
英语中的时态可表示不同的时间与方式.在写较长或较复杂的句子时,要保持时态的一致性.如：
(1)
1 was a high school student then, from a low-1ncome family. So I he to work to support my family. 这里的he应改为had,因为“he to work”是在“1 was a highschool student”时发生的.
(2)
There are many advantages for students to workwhile studying at school. One of them was that they can earnmoney.这里的was应改为1S.因为这个句子的主体时态是现在时.
2 人称和数一致
不仅句子中谓语动词必须和主语的人称和数要保持一致,而且代词也应与所指的名词保持一致.如：
(1)
Compared with China´s education, foreign education he many problems.这里的he应改为has,主语是单数,故谓语动词也应该用单数.
(2)
Thank you so much for your party at ChristmasEve. All of them enjoyed it very much. We liked the dishesyou had cooked and we were happy to learn the English songsyour taught us.这里的them改为us,通过上下文可以看出,这个代词应指“我们”.
(3)
What is more, you he to be friends with yourpupils and take good care of him.这里的him应改为them．这个代词指pupils.
3 语态一致
英语中语态是用来说明谓语和主语之间关系的一种形式.它分为主动语态和被动语态两种.在并列句、复合句中应尽量保持语态一致,否则会使句子晦涩难懂.如：
(1)
We couldn´t solve the problem by ourselves andhelp was given to us by the teacher.应改为…and the teacherhelped us.
(2)
No work was done before they prepared the computer.应改为…before the computer was prepared.
4 语气一致
语气表示说话人对某一行为或事情的看法.它分为：直陈语气、祈使语气和虚拟语气三种.句子中的语气应保持一致,不能将这三种不同的语气混用在一个句子中.如：
(1)
1 would ask Tom to lend me the money i{I knowhlm.这里的know应改为knew.主句用了虚拟语气,从句也应该用虚拟语气.
(2)
Be attention, please, and then you will look at themap on the wall.将直陈语气改为祈使语气：Please be attention．look at the map on the wall.这样两个句子才具有了连贯性.
5 结构一致
由and , or , but , either. , .or , neither. , ．nor , notonly.一．but also,as well as等并列连词或词组连接的平行结构在词性、时态、非谓语动词等形式上一定要前后一致.如：
(1)
Modern people know more about health, he better food, and to live in cleaner surroundings. 应去掉to, and连接的是三个并列谓语.
(2)
My brother is good not only at painting but alsoplays basketball well. not only---but also连接的两个成分不一致,应改为：¨.not only at painting but also basketball.
只有保持句子结构的连贯性,才能使整篇文章衔接自然流畅,严密紧凑,因此它是写出高质量英语短文的基础,教师应加强这方面的训练.
