hot potato.
hot的意思是热或烫.Potato就是土豆.热的土豆固然好吃,但是它会烫你的手,你会想法马上甩掉的.Hot potato作为俗语,它的意思就是一个争论很激烈的问题,没有一个人愿意为它承担责任.例如：
例句-3:The question of whether to raise taxes to cut the budget deficit is a real hot potato for a lot of politicians.
这个人说：“是否用增加税收的方法来减少预算赤字的问题对于许多政客来说是一个棘手的问题.”
下面这个例子是一位律师在给另一位律师提供建议：
例句-4:If I were you,I'd drop that client like a hot potato; he's always suing somebody for something,but he usually loses and he doesn't pay his lawyer's bills.
这个律师说：“要是我是你的话,我就把你那个顾客马上甩掉.他老是为了什么事去告别人,可是他总是输给别人,他还往往不付律师费.”
