We may/might as well take the opportunity to do...= It would be better if we took the opportunity

问题描述:

We may/might as well take the opportunity to do...= It would be better if we took the opportunity
后面的took为什么要用过去时态?可以用现在时吗?

这是因为该句子是带虚拟语气的句子
If I knew his telephone number,I would tell you.
如果我知道他的电话号码,我就会告诉你.(事实:不知道)
虚拟语气详见
