文档介绍：行文格式
Manuscript Form

(,)(Comma)
逗号表示句子内部的一般性停顿。例如:
●When she came,1 was busy washing my coat.
当你说完came后稍停了一下,那也就是把这个句子写出来时该打一个逗号的地方。但有时由于句子结构的需要也用逗号,即使在没有停顿的地方也一样。
yet,but,or,for,so,nor,and等的前面用逗号。例如:
●She asked the question in a loud voice,but no one answered
●She was tired,and she decided to have a rest
●Hurry up,or you’ll miss the plane.
●She couldn’t go to the park to meet him,nor could she send anyone instead of her.
●It must have rained last night,for the ground is wet.
●He is a clever boy,yet you can’t help liking him.
如果两个或两个以上的并列从句在句式上都很简短,意思上又紧密相连,那么它们之间可以不用连词而只用逗号。例如:
●A memoir is history,it is based on evidence.
- E. M. Forster
上面这种逗号的用法属于特殊情况,在文学作品中有时可以见到。
,或放在句子中间时,后面应该用逗号。例如:
●When the bell rang, the children rushed out of the classroom.
●In the ancient palace, they saw the throne where emperors used to sit.
●To see the importance of this road, one has to look at a map.
●Born and brought up in the South, she is not used to eating wheat.
●The audience,interested in the topic, asked the speaker many questions.。
如主语前的状语成分很短,其后可不加逗号,当然也要考虑避免造成误解。例如:
●On hearing the big noise I knew something terrible had happened.
●In one corner of the hall they found the injured dog.。
如果主要从句在前,状语成分在后,逗号一般要被
●You’ll be unable to finish the work in time if you don’t start at once.
●I was trying to reach her by phone when she walked into my office.
●He found the document in one of the drawers of his desk.
。例如:
●She buys beer, milk, vegetables, and many other things from this supermarket.
在不会造成误解的情况下,连词前面的逗号可省略。
。例如:
●Zhang Hua, who is the best student of the class,will go to a famous college.
●He had to leave his hometown, where he had 1ived ever since he was born.
●Mr. Li, the new chairman of the department, will speak at the meeting.
●An old lady, nodding and smiling, invited us in.
如果是限定性定语从句和短语则不需要用逗
