conyersely和onthecontrary的区别？
首先，应该是conversely，副词，相反地；通常比较相对客观
英文解释 1.You say conversely to indicate that the situation you are about to describe is the opposite or reverse of the one you have just described.
2.used for introducing a sentence, or part of a sentence, which says something that is the opposite of the other part。
例如：
In real life, nobody was all bad, nor, conversely, all good.
在现实生活中，没有彻头彻尾的坏人，相反地，也没有完完全全的好人。
Some wrong answers were marked right and, conversely, some rightanswers had been rejected.
on the contrary是词组，表示正相反；相反，反之，通常有点主观与个人色彩,认为后面才是对的。
英文解释 1.you use on the contrary when you have just said or implied that something is not true and are going to say that the opposite is true.
2.used for emphasizing that something is true, even though it is theopposite of something that has been said
例如：
It doesn’t seem ugly to me; on the contrary, I think it’s beautiful.
在很多客观情况下，两者都可以
