cannot和cannot请问cant和cannot再用法上的

请问can’t 和cannot再用法上的区别以及意思··· 谢谢·

can't=cannot。
其实我觉得你的问题应该是cannot 和can not 的区别。事实上，这两个是不一样的。

Cannot是“不可以”，而can not是“可以不”。
举个例子：

I cannot believe this! （我无法相信！等于I can't believe this!）
I can not believe this! （我可以不相信！也就是说，I can believe this, or I can not believe this。
我并不一定要相信，我可以选择不相信。）

CAN NOT vs。 CANNOT的英文解释是这样的：
What we should use when we mean "are unable to" or "are not permitted to" is one word: cannot。
This is the word that we contract when we write "can't。" It is a common error to separate "can" and "not。" The American Heritage Dictionary is quite clear on this point: cannot is the negative form of the word can。


Here's one example I use:
If I say "I cannot smoke," I mean that I am unable to or not permitted to smoke。
If I say, "I can not smoke," not modifies smoke。 My meaning is: "I am able to not smoke," i。e。, I have the ability to avoid smoking, to prevent myself from smoking, or to stop smoking。


Another example:
If I am unable to go or am not permitted to go, I should write, "I cannot go。
" If I have a choice between going and not going, I may write, "I can go, or I can not go – it is my choice。"

To all my fellow nitpickers out there: I am fully aware that the two-word construction "can not" is often used where the opposite of "can" is intended。
Despite the ubiquity of this usage, it is still an error。
