It is good ____ to thank the person who has done you a favour.
A. attitudes B. attitude C. manners D. manner 选C Why?

It is good/bad manners to do sth.
做什么事是有/无礼貌的。

感谢曾经支持你的人是有礼貌的。

从句意‘别人帮你做事后对别人表示感谢是一种礼貌’排除A与B， 而礼貌这个词用在句中要用复数（固定用法），故C对

c it is good manners to do sth 干。。。是有礼貌的行为
good manners 有礼貌
bad manners 没礼貌

c it is good manners to do something 固定用法
