You cannot be too careful when you drive a car .

cannot ....too ....什么意思
cannot ....enough....什么意思
其中的too能换成enough吗?
谢谢大虾门!

You cannot be too careful when you drive a car .

你开车的时候再小心也不为过
cannot ....too ...再...也不为过,越...越好
You cannot be enough careful when you drive a car 你开车的时候不需要这么小心.
cannot ....enough这中用法不常见,不太符合人的思维习惯

cannot ....too 意为 无论如何...也不过分,这句话的意思是“当你开车时,无论你如何小心也不过分。”相当于:You should be as careful as possible when you drive a car.
cannot...too有几个变体结构,我们可以用impossible,difficult
等字去代替cannot;以enough,difficulty,sufficiently,exaggerate,to over-等字去替代too.
下面的一些句子就是"cannot...too"结构的变体:
I couldn't get home fast enough.
我恨不得马上回到家里.
You cannot take sufficient care.
你要特别小心.
The importance of this session cannot be exaggerated.
这次大会极为重要.
No man can have too many friends.
朋友愈多愈好.
