hence和therefore的区别

therefore的用法

therefore可引出一个独立句，但不能连接两个句子，因此当therefore前没有and等连词时，前面须用分号。连接副词therefore用于句首时后面无需逗号，若位于句中前面可加也可不加逗号。therefore也可用于推理，作“故…由此得出”解。

therefore的用法例句：

The truth is that junk bonds were misnamed,and therefore misunderstood。事实上人们对垃圾债券的称谓有误，所以产生了误解。They had seen him trawling and therefore knew that there were fish。他们曾见过他用拖网捕鱼，因此知道那里有鱼。

hence词组

from hence从这里；hence with拿开；带走。hence例句：For centuries,medicine was impotent and hence unproblematic。几个世纪以来，医学无能为力，因此没有问题。The true consequences will only be known several years hence。真正的后果只有在几年之后才能知道。
