用苹果比橘子？

呵呵,当然不是这个意思了.这是个俗语. 先看看英英解释:

to examine the similarities of things that are completely different. Comparing the average wages of workers and managers is like trying to compare apples and oranges.
Usage notes: usually used to explain that two things cannot be compared

汉语里面有个俗语和它很像,就是风马牛不相及. 这么一说应该懂了吧,苹果比橘子根本是两码事,不能放一块比较,简直就是关公战秦琼.

所以compare apples and oranges意思就是把毫不相干的人或物硬凑在一起作比较。

• trying [´traiiŋ] a.难堪的；费劲的 (四级词汇)
