逗号(comma)是英文书写中常用的标点符号，可以切分意群，表示停顿等等，下面就让我们来学习一下逗号的五种具体用法吧。
1、Using commas in lists 用在并列词语中
要用逗号隔开一系列并列的事物，让我们看看下面的例句：
Saturday morning started with a hearty breakfast of scrambled eggs, bacon, sausage, and French toast.
2、 Using commas in direct speech 用在直接引语中
直接引用别人的原句称为直接引语。直接引语需要在前引号前用逗号来引导。让我们看看下面两个例句：
Steve replied,"No problem."
3.、Using commas to separate clauses 用来划分主从句
用逗号划分主从句可以使句子结构更加清晰明白，让我们看看下面例句：
Having had lunch, we went back to work.
4.、Using commas to mark off parts of a sentence 用逗号插入成分
英文写作中常出现用两个逗号插入成分的情况，用于解释说明前文内容，或者表达作者态度等等。看下面例句：
Cynthia’s daughter, Sarah, is a midwife.
5、Using a comma with 'however' 用在“however”后
However有两种意思：
（1）当用作副词，表示“然而，可是”后面需要使用逗号，如：
This was not an easy decision. It is, however, a decision that we feel is dictated by our duty.
（2）当其用作连词，表示“不管怎样”则不能使用逗号，如：
However we adopt healthcare reform, it isn't going to save major amounts of money.本回答被网友采纳
