英语句子中如何正确使用逗号
在英语写作练习中,标点符号是最容易忽视的问题.有的学生整篇文章一逗到底;有的则相反,全文都用句号.这样,无论文章的内容多好,结构多紧凑,逻辑性多强,但由于标点符号错误过多,文章变得不知所云.逗号是最常见的标点符号之一,也是使用中出现错误最多的.典型错误如下:
 He promised to come to the meeting,however,he didn’t appear.
 I didn’t know,where I should go.
 We realized,that the girl was a foreigner.
N,如何正确使用逗号呢?
1. 都好用来隔开句中的并列成分,在最后两个成分的连接词之前,一般不用逗号;但如果最后两个成分太长,最好用逗号隔开,以免引起歧义.例如:
The children sang,danced,jumped and chased each other.
I spent yesterday playing basketball,drinking beer,and telling stories.
2.逗号用来连接并列成分,用在连接词and,but,for,so,nor,yet 等之前.例如:
He wanted to go on,but other people disagreed.
The young man tried,yet he failed to convince her.
但应注意:在汉语中,单独的逗号可以连接分句;在英语中,一般来说逗号必须与连接词一起才能连接并列分句,否则是错误的.
2. 句中的名词性从句(如that,what,where,when,if等引导)作动词的宾语是,该从句之前不用逗号.例如:
Tell me what you are going to do.
Tom wondered if the dinner was ready.
4.状语从句、介词短语或分词短语在句中作状语,放在主语之前或插在句中,其后应该用逗号,若置于逐句之后,则不用逗号.例如:
Some listeners,bored by the lengthy talk,closed their eyes and dosed off.
To my delight,he passed the entrance examination of our institute.
Come and look me up if you are ever in Beijing.
5.句中如有限制性从句或词组(即需要用从句给修饰词以明确的含义)时,不用逗号;如果是非限制性从句或词组,则需要用逗号把它与句子的其他部分隔开.例如:
This is the lab where students listen to tapes and see films.
Mr.Li,the new CEO of the company,will soon announce his plan for reforms.
6.当修饰全局的状语置于动词个部分之间,或主语与动词之间,或动词与主语之间时,用逗号把它和句子的其他成分隔开.例如:
My father had,surprisingly,kept his temper all day.
They were,believe it or not,in love with each other.
7.逗号把同位语、插入语、独立成分与句中的其他成分隔开.例如:
This is Zhang Hong,monitor of Class 1.
The machines you have supplied us with,I’m glad to tell you,work very well.
Many interesting places in Beijing,such as the Summer Palace and Temple of Heaven,attract thousands of visitors daily.
“Tell me,” he said,“what did you think of the discussion?”
8.英语中的日期、地址及四位数以上的数字表达中,逗号也是很重要的,如果表达日期的顺序是:month—day—year,在年之前必须用逗号.
Hongkong was returned to China on July 1,1997.
如果日期的顺序是:day—month—year,则没有必要用逗号.例如:
The girl was born on 15 May 1991.
在表达四位数以上的数字时,为了便于读数,一般从右向左,每三位数之间用逗号隔开.例如:
67,865,243 1,876,468,200
地址表达的例子如下:
My address is “52 Yinzi Lane,Xidan,Beijing.”
9. 如果句中出现therefore,however,nonetheless,hence,otherwise,besides,moreover等连接副词时,它们不能用作连词来连接两个并列分句.许多学生常常把这些词误用为连词,之前用逗号,这是不对的,应该用分号.例如:
Our monitor didn’t hear the report; therefore,he didn’t know what new decisions were made.
以上对逗号的种种用法作了简单的分析.标点的正确使用会使文章表达清晰,通顺易懂.因此,逗号这个看似简单却常常被人忽视的小问题,应该受到人们的重视.
