What a pity!considering his ability and experience ,he ( ) better

问题描述:

What a pity!considering his ability and experience ,he ( ) better
A need have done B must have done
C can have done D might have done
不应该译为“他们本可以发挥更好”嘛~为什么用D~

翻译的对啊,但是没有can have 这个用法,应该是could have done唔……那might have done 的话在这里面怎么翻译呢?might=may,可以翻译成本来可以,但是语气更柔和。
