中国自古以来文书没有标点符号，五四运动前后才借鉴西方逐步引入标点符号。所以，逗号等标点符号在中文的作用不是很重要。这也导致了我们不重视英文标点符号的使用的部分原因。

但是，英语书写中，逗号的作用至关重要。尤其正式的书面表达对语法的要求尤其严谨，任何一些细微的错误，在某些场合中会被放大几十倍。2006年Major Canadian Company由于商业合同中一个逗号使用错误，造成了上百万美元的损失。

逗号的用法总结如下。

注：英文没有顿号（、），中文用顿号处，英文用逗号。

逗号在句中表示一般性停顿。举例：When he came, I was busy cleaning my room.

你说完came后停顿了下，那么，此句写出来时，came后要加逗日本网站网址号。除了表示停顿，语法上，根据句子结构，即使在没有停顿的地方，也要用逗号。如下：

1. 并列句中，连词（and, but, or, for, so, nor, yet）前用逗号

He asked the question in a loud voice, but no one answered.

We were tied, and we decided to have a rest.

Come early, or you will miss tsmc玻璃钢he show.

It must have rain last night, fo低俗生活r the ground is wet.

He is an eccentric, yet you can’t help liking him.

但，如果2个或3个并列从句很简短，意思又紧密相连，它们之间也可不用连词，只用逗号。比如：A memoirvisa信用卡 is history，it is based on evidence.——E.你懂的网址M.Forster。这种用法是特殊情况，比较少见，通常情况下，逗号不能连接前后完成的句子，必须要有连词。举例如下

The teacher came in, we were talking.错误

When the teacher came in, we were talking. 正确

“the teacher came in”和“we wer同工不同酬e talking”都是主谓宾完整的句子，必须加连词，比如when

2. 状语从句或短语（包括介词短语和分词短语）放在句首（主语前），或位于句子中间时，后面应用逗号。

In the ancient palace, they saw the throne where emperors used to sit.

Born and brought up in the Sourth, she is not used to eating wheat.

The audience, interested in the topic, asked the speaker many questions.

如果主语前的从句或短语很短，其后可省略逗号，举例如下：

On Friday I have an exam. Friday后省略了逗号

On hearing the 小蜜蜂游戏big noise I knew something terrible happened.

In one corner of the room they found the injured cat.

如果状语从句位于主句后，一般省去逗号。举例如下：

The teacher dismissed the class when the bell rang.

You will be unable to finish the work in time if you don’t start at once.

3. 非限定性定语从句或短语，必须用逗号隔开。
