分号 Semicolon
分号最常用于两分句之间，其分隔度较逗号为，大但较句号为小，通常用作表示句子中两分句意思相连。
（1）以分号化替句号来分隔两相关独立分句（Independent Clauses）.
Independent clause; independent clause.
例子：
The student parking lot is half empty at 3:30p.m.; this must be a commuter campus.
Spring is here; the birds are warbling with joy.
注意：
如果使用 coordinating conjunction (for, and, nor, but, or, yet or so)，则用逗号 comma，而不是分号，详情请看逗号部分的讲解。
（2）当其中一独立分句（Independent Clause）中包含逗号时，以分号来分隔两分句.
Independent clause; coordinating conjunction independent clause,containing commas.
Independent clause, one thatcontains commas; coordinating conjunction independent clause, one that contains commas.
例子：
For anything worth having one must pay the price; and the price is always work, patience, love, self-sacrifice.
（3） 当要使用连接副词（Conjunctive Adverbs, e.g. therefore, however）或其它连接语（Transitional Expressions, e.g. in addition, on the other hand）来联结分句时，以分号作分隔.
Independent clause; conjunctive adverb or other transition expression independent clause.
例子：
His mother claimed to be interested in swimming; however,she didn’t know the difference between orthodox breaststroke（蛙式）and butterfly stroke（蝴蝶式）.
If you give children too much freedom, they willnever learn to control themselves; on the other hand, if you give them too little,they will never become self-reliant.
（4） 利用分号来分开较长或含有逗号的串联字、短语或分句.
Independent clause that includes a series of items, each or all of which contain commas, another item in the series, another item in the series.
例子：
We need the following representatives: a person who speaks Mandarin, Japanese, or Korean; a lawyer with a background in civil rights; and a professor of art, literature, or some other area within the humanities.
（5） 避免错用分号
I）主从复合句之间，不使用分号
例子：
错误句子：Although the new computers had arrived at the college; the computer lab was still being built.
正确句子：Although the new computers had arrived at the college, the computer lab was still being built.
II）介绍资料或名单时，不使用分号，而是用冒号（：）
例子：
错误句子：The students’ demands included the following; an expanded menu in the cafeteria, better janitorial services, and more up-to-date textbooks.
正确句子：The students’ demands included the following: an expanded menu in the cafeteria, better janitorial services, and more up-to-date textbooks.
