thereby和therefore的区别？

请不要复制词典的内容！最好给出一些例子来，谢谢！

thereby:
By that means; because of that.
因此：那样；因此
In connection with that:
由此，从而：与那个相关联：
“And thereby hangs a tale”(Shakespeare)
“因此，这事儿有由来”(莎士比亚)
He became a citizen, thereby gaining the right to vote.
他成了公民，因此有投票权。
there;
因此；所以
I was ill, and therefore could not come.
我病了，所以没能来。
He has broken his leg and therefore he can't walk.
他摔坏了腿，因此不能走路了。
We do not have enough money. Therefore we cannot afford to buy the new car.
我们的钱不够,因此买不成这辆新车。
（用于推论）因而，因此
He was the only candidate; therefore, he was elected.
他是唯一的候选人，因此，他当选

thereby: 因此：那样 He became a citizen, thereby gaining the right to vote therefore; 因此；所以 一般引导句子 It is raining,therefore,we can't play football outside

therefore= for that,前面所描述情况前提等是后面描述情况的原因 thereby = by that前面所描述情况等，是后面描述情况的前提条件，方式等。 多斟酌一下 for 和by的区别有助于了解这两个词有什么差别吧。。 go back to your hometown，and you can thereby bring me some souvenirs 这里回乡下应该是拿回纪念品的前提，方式；如果硬改成therefore讲成原因显然不合情理 另外：therefore可以单独开来，thereby不能单独用 如：i love you. therefore, i forgive you.

therefore; 因此；所以 一般引导句子 It is raining,therefore,we can't play football outside thereby: 因此：那样；因此 很少使用，在英文诗里到可以见到，比较迂腐正规！
