EAT的三种在英语中的习惯用语
Eat one’s cake and have it(或have one’s cake and eat it)同时做两件不相容的事而双收其利
这个比喻多用在否定句，意指“两者不能兼得”，或用在讽刺性的句子中而意指“想双收其利”，强调在两件不相容的时间中不可能双收其利。
【例】the clerk was disagreeable because everyone was on holiday during August except himself; but as he had had a holiday in June we told him he couldn’t eat his cake and have it.这个职员很不满意，因为在八月份，除了他，大家都休假；但他在六月里已休了假；我们告诉他，他不可能双收其利。

Eat (或tear) one’s heart out苦恼，憔悴；忧伤过度，忧心如焚
最早使用这个比喻的是荷马.李丽在一五七九年说过：“别忧伤过度。”（not to eat our heartes .）这里的out是后来加上去的，在英国桂冠诗人埃德蒙.斯宾塞的《仙女昆妮》中，在托马斯.德雷克斯的一六一六年收集的谚语中，在伯顿的《忧郁症分析》中以及在培根的杂文中引用这条成语时都不用out.这个表达形式可于cry one’s eyes out相比。
【例】he was eating his heart out because he could not go with the expedition, but his health was not good enough to stand the hardships.他因不能参加探险队而苦恼，可是他的身体不太好，不适于探险。
