"If you'd been minutes earlier,you would have seen the doctor."

It means that you were minutes late,and that you failed to see the doctor.
这意味着你迟到了几分钟,且没见到那位大夫（或许是博士）It means that you were to be late.可以换成It means that you were late.吗？求解释.........我都翻译了， 刷新再看。不是可不可以换， 而是必须换成It means that you were late为什么是you were to be late呢？答案这么说的不是“you were to be late”， 我不是说了吗？应该是It means that you were late。原句是表示与过去事实相反的虚拟语气， 意为：如果你早来几分钟， 你就可以看到那位大夫了。言下之意就是， 你来晚了，所以没看到。明白？
