Change their change one's mind 和 make up one's mind 那个mind能加S那个不能加?短文纠错 有个change his mind 是对的,但阅读里有change their minds 到底变不变? change their minds还是change their mind? 是 the change in their numbers 还是 the changes in their numbers 这句话意思 是 改变自己,为什么不是To change myself 而是To change their呢,请教哈 know和know about哪个了解的程度更深?改变他们的主意是change their mind还是change their minds? make up their minds是加s还是不加s.我觉得这里mind是决心的意思.应为不可数.大家认为呢.还有change their mind是可数还是不可数.我认识是可数.取意见之意.可是我的想法和答案上不一样.到底该怎么 I want to try to change their..
