分号
分号有以下用法:
1.把没有连词连接而意思上都有联系的句子连接起来(可以用句号,但这时意思会被断开;也可用逗号,可能力量较弱不能把两句拉在一起;也可用冒号,但现在这样用时比过去少了):
It won't last long;it's too weak.
He is a clever fellow;even his enemy admits it.
I love you;I worship you;I want you.
He is content;he lives happily.
2.把内部包含有逗号的两个句子连在一起(这时不宜用逗号):
Dick is a generous,large-hearted person;but John,Mary and some of his friends are selfish people.
(Cf.Dick is a generous man,but John is a selfish fellow.)
Alan ran his business carefully,methodically,and efficiently;and he was a great philanthropist,too.
He has three wives:one,who married him 20 years ago;a second,who was a rich widow;the third,who has al- ready married five times.
3.用在后面跟有逗号的连接副词之前:
He studies hard;moreover,he has to work for his living.
He has squandered all his wealth;therefore(或as a result),he has to beg his bread.
4.用在两个并列从句或两个短语之间(这时也可用逗号,但对比性较弱):
We know that country life is more quiet than city life;that it is more healthful;that it is happier.
To work eight hours;to sleep eight hours;to do other things eight hours—that is the best way for man.
That depends upon who do it;how they do it;and when.
5.用在such as,that is这类词前:
We learn several subjects;such as(or e.g.)chemistry,and physics.(These are some of the subjects we learn.)
We learn several subjects;that is(or i.e.viz,to wit, namely),chemistry,physics,maths and biology.
(These are all the subjects we learn.)
—在这种句子中也可用逗号或冒号代替分号:
We learn several subjects,namely chemistry,physics, and mathematics.
We learn several subjects:namely,chemistry,physics, and mathematics.
We learn several subjects,namely,chemistry,physics, and mathematics.
—但在下面这种句子中逗号、冒号或分号都不需要:
We learn such subjects as chemistry and physics.
