初学英语的人应该注意理解句号、逗号和问号。中级到高级的学生还应该学习如何使用冒号和分号，以及偶尔的感叹号。
今天介绍使用句点、逗号、冒号、分号、问号和感叹号的基本规则。每种标点符号后面都附有解释和例句，以供参考。
一：Period（句号）
用句号结束一个完整的句子。 句子是一组包含主语和谓语的单词。 在英式英语中，一个时期称为“full stop”。
Examples:
He went to Detroit last week.
They are going to visit.
二：Comma（逗号）
英语中逗号有许多不同的用法。逗号用于:将项目列表分开。这是逗号最常见的用法之一。请注意，在连接词“and”之前包含了一个逗号，它出现在列表的最后一个元素之前。
Examples:
I like reading, listening to music, taking long walks, and visiting with my friends.
They would like books, magazines, DVDs, video cassettes, and other learning materials for their library.
单独的短语（从句）。尤其是在开始从句或长介词短语之后。
Examples:
In order to qualify for your certificate, you will need to take the TOEFL exam.
Although he wanted to come, he wasn't able to attend the course.
分隔两个独立的子句，这些子句通过诸如“ but”之类的连词连接。
Examples:
They wanted to purchase a new car, but their financial situation would not allow it.
I'd really enjoy seeing a film this evening, and I'd like to go out for a drink.
使用直接引语(与间接引语相反，如:He said He wanted to come…)
Examples:
The boy said, "My father is often away during the week on business trips."
His doctor replied, "If you don't stop smoking, you run the risk of a heart attack."
单独的同位句(名词或名词短语)或非定义关系从句。
Examples:
Bill Gates, the richest man in the world, comes from Seattle.
My only sister, who is a fantastic tennis player, is in great shape.
三：Question Mark（问号）
问号用在问题的末尾。
Examples:
Where do you live?
How long have they been studying?
四：Exclamation Point（感叹号）
句末使用感叹号表示非常惊讶。 指出重点时也用于强调。 注意不要太频繁使用感叹号。
Examples:
That ride was fantastic!
I can't believe he is going to marry her!
五：Semicolon（分号）
分号有两种用法:分隔两个独立的分句。其中一个或两个从句都很短，表达的意思通常很相似。
Examples:
He loves studying; he can't get enough of school.
What an incredible situation; it must make you nervous.
分隔以逗号分隔的单词组。
Examples:
I took a holiday and played golf, which I love; read a lot, which I needed to do; and slept late, which I hadn't done for quite a while.
They plan to study German, for their travels; chemistry, for their work; and literature, for their own enjoyment.
六：Colon（冒号）
冒号有两个用途：提供额外的细节和解释。
Examples:
He had many reasons for joining the club: to get in shape, to make new friends, to lose some weight, and to get out of the house.
She gave notice for the following reasons: bad pay, horrible hours, poor relations with colleagues, and her boss.
引入直接引号（在这种情况下也可以使用逗号）。
Examples:
He announced to his friends: "I'm getting married!"
She cried out: "I never want to see you again!"
