一般说来，分号的作用介于逗号和句号之间，即用分号隔开的两部分之间的关系，比用句号隔开的紧密，但不及用逗号分开的紧密。当两个主句没有任何连接词连接而出现在同一个句子中时，分号可起到替代连接词的作用。它常用于分隔没有连接词的句子，但一般不用在从句之间。简单地说，分号一般表示的是分句与分句之间的并列，主要用法有以下四点。

1.分隔没有连接词连接的独立分句。

In the past，boy babies were often dressed in blue；girls，in pink.

Our power to apprehend truth is limited；to seek it，limitless.

You don’t write because you want to say something；you write because you’ve got something to say.

2.分隔已有逗号的并列成分，以避免歧义。

Follow this procedure：first，get your application forms；next，fill them out；last，pay the charge.

While the man worked to strengthen the dam，the rain continued to fall；and the river，which was already above the usual level，rose higher and higher.

3.下列各词和短语若用于连接复合句时，常与分号连用：then，thus，hence，indeed，consequently，also，moreover，besides，furthermore，meanwhile，in other words，however，on the other hand，otherwise，instead，at the same time，in fact等。

Tom is well-liked；in fact，he is the most popular person in the class.

The weather was cold for that time of the year；nevertheless，we set out to hike to the top of that mountain.

According to one national survey，high school boys expected a starting salary of $2，000 for their first full-time job；on the other hand，high school girls expected a starting salary of only $1，500.

4.在群发电子邮件时，常用分号隔离不同的邮箱。

c. 答案为B。逗号后接的是一个which引导的非限制性定语从句。

d. 答案为A。分号暗示前后为并列关系，所以选复数代词them，用来指代前面“收集的邮票”（collections of stamps）。
