题目

英语翻译
A "favor" is doing something for another person that the doer has no obligation to do,for example,going to the store for a friend or mailing some letters so that a sick friend wouldn't have to go out in the rain.Since a favor involves doing sonething extra,it requires an expression of thanks.It is appropriate to thank the person again after the favor has been done.For a "bigger" favor,that is,one involving more time or effort ,the beneficiary may also give a gift to the doer of the favor.For small things,such as holding open a door ,a person simply says"Thanks".
Always thank someone who offers to help you,whether you accept their help or refuse it politely .When refusing an offer of help ,you may want to say something like:
NO,thank you .
NO,but thank you for offering.
Thank you,but I'll manage OK by myself.

答案

“做好事”,就是去为另一个人做不是自己义务范围内的事情,例如去帮朋友去士多店购物,或者帮一个病倒在床的朋友去寄出一些信,那样他就不用冒着雨出去了.一件好事往往包含了做其它额外的东西,需要表达一下谢意.当这件好事做完了之后,应该再一次的感谢对方.对于一件更大的好事,就是说,这件事需要更多的时间或者付出,受益人也可以给做好事的人一些小礼物.具体地说,就比如你帮对方稳着打开的门,那他就会说一句简单的“谢谢你”.
要经常对那些帮助你的人表达谢意,不管你接受了,或者婉转地拒绝了他们的帮助.当你拒绝他人的好意时,你可以说些这样的话：
不,
不用了,感谢你的好意.
但我自己可以搞定的了.
很久很久没有翻译过英语了,所以显得……比较生硬……
另外不是很确定Since a favor involves doing sonething extra,it requires an expression of thanks.怎么翻译,因为我对有Since在的语句并不熟悉.我承认我这句翻译得很烂……
而且应该是Something而不是Sonething.
