W：How did your interview go？
M：I couldn't feel better about it！The questions were very fair，and I seemed to find an answer for all of them．
Q：What is the man's attitude about the interview？
It has never been easier to insult people inadvertently．Ayoung lady offers her seatin a crowded bus to an elderly，frail gentleman，and he gives her a dirty look because she has insulted his manhood．
其实，只要他们知道比较级用于否定结构可表“最……不过”这一语法现象，就会懂得“I couldn't feel better about it”意为“我对那次面试的感觉再好不过了”；“Ithas never been easier to insult people inadvertently”意为“人们非常容易无意之中冒犯别人。”
1．该结构多为“can't ／couldn't ＋比较级”的形式。例如：
1）I can't agree with you more．我再同意你不过了。（或：我完全同意你的意见。）
2）The weather couldn't be worse．天气再糟糕不过了。
3）He couldn't have done better．他做得再好不过了。
1）This could give her no greater pleasure．这使她再高兴不过了。
2）She's never better．她现在最好不过了。（或：她比以往任何时候都好。）
3）There's nothing cheaper．这东西再便宜不过了。
1）He couldn't care more．他非常介意。（或：他最关心不过了。）
He couldn't care less．他毫不介意。（或：他最漠不关心了。）
2）He had never felt more like talking to anyone．他从未如此想和人谈话。
He had never felt less like talking to anyone．他从未如此不想和人谈话。
4．当no表示“not at all”之意时，可以作为副词放在比较级词语前面。这时，“no＋比较级”的意思并非“最……不过”。例如：
1）Are you really fifty？You look no older than thirty-five．你真的五十岁了？看起来不超过三十五岁。
2）Some people can eat what they like and get no fatter．有些人想吃什么就吃什么，一点也不发胖
