習(xí)慣用語 【2】

to cost an arm and a leg
    Definition: to cost a fortune；be very expensive
    這個慣用語的意思其實很容易從字面上理解出來。cost在這里就是花費的意思。也就是我們通常說的It costs $100中的用法。如果買一個東西要花上一支胳膊加一條腿，那就可想而知有多貴了。所以我們今天講的慣用語意思就是非常貴，要花大價錢。這個慣用語結(jié)構(gòu)比較簡單，最簡單的例子：This car costs an arm and a leg.是不是很好用呢？
    Example
    Sarah : Excuse me. Could you tell me how much this watch costs?
    Clerk : Certainly Miss. This watch is 600 dollars.
    Sarah : Six hundred dollars?! That's a bit much. Do you have any watches that don't cost an arm and a leg?
    啊哈，看來我們的Sarah買表的想法就是不要把腿呀、胳膊什么的也給搭進去了。
