adv.因此；所以
He was the only candidate; therefore, he was elected. 他是唯一的候选人，因此，他当选了。
We do not have enough money. Therefore we can not afford to buy the new car. 我们的钱不够,因此买不成这辆新车。
He was very tired, and therefore he didn't give the market report. 他非常疲倦，所以没能作市场报告。
therefore的意思是“因此,为此,所以”,是副词,引导结果、结局或结论,不能误作连词用。
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。
