英语写作中分号的运用
解释一：
分号有时又称为小句号。它表示一个停顿，其停顿时间在逗号与冒号的停顿时间之间。文章如采用许多分号，其风格则变得严肃、正式。为了正确使用分号，有必要先学会辨认主句。当两个主句没有任何连接词（and, but, or, nor, for）连接而出现在同一个句子里，这时最好采用分号使之分离。分号的主要作用很简单，它常用于分离没有连接词连接的句子。
解释二：
英语的句号表示一条句子的终结，但有时当两个句子的关系紧密，我们不希望因为用了句号而打断了思路时，就会考虑用分号。英语分号停顿的时间比逗号长，比句号短。
这里我只考虑当第二个分句以某些过渡词如 however, nevertheless, of course，for example, on the contrary, consequently, as a result 等开头时，用分号。
其它情况，如果自己不熟悉，就不要用分号了。
