標點符號雖然小，惹出事情真不少。因為用錯了標點符號或是點錯地方而造成的歧異和糾紛也不少。這次我們就來看看標點符號都該怎么用吧。

1. 句號 Period [.]
用以表示一個句子的結束：
Hockey is a popular sport in Canada.
The federal government is based in Ottawa.

用在縮寫中：
B.C. is the province on the West Coast.
Dr. Bethune was a Canadian who worked in China.
The company is located at 888 Bay St. in Toronto.
It is 4:00 p.m. in Halifax right now.

2. 問號 Question Mark [?]
在句子的結尾使用問號表示是直接疑問句：How many provinces are there in Canada?

注意：在間接疑問句結尾不要加問號：
The teacher asked the class a question.
Don't ask me why.

3. 嘆號 Exclamation Mark [!]
在句子的結尾使用嘆號表示驚訝、興奮等情緒：
We won the Stanley Cup!
The forest is on fire!

4. 逗號 Comma [,]
句子中的停頓：Therefore, we should write a letter to the prime minister.

在疑問句中引出說話人："I can come today," she said, "but not tomorrow."

排列三個或以上的名詞：Ontario, Quebec, and B.C. are the three biggest provinces.

引出定語從句：Emily Carr, who was born in 1871, was a great painter.

5. 單引號 Apostrophe [']
表示所有:This is David's computer.
These are the player's things. (things that belong to the player)

Note: 對于復數形式的名詞，只加'
These are the players' things. (things that belong to the players)

縮寫I don't know how to fix it.
