[转载]compare to 与compare with 的区别

These are sometimes interchangeable, but when you are stressing similarities between the items compared, the most common word is “to”: “She compared his home-made wine to toxic waste.” If you are examining both similarities and differences, use “with”: “The teacher compared Steve’s exam with Robert’s to see whether they had cheated.”

compare with与…比较，compare to比喻为

compare...with...把……和……比较(常表示同类相比，比较)

①Let's compare this article with that one. 让我们把这篇文章和那篇文章作一下比较。

②The heart is often compared to a pump. 心脏常被比作水泵。

To compare to is to point out or imply resemblances between objects regarded as essentially of a different order;


to compare with is mainly to point out differences between objects regarded as essentially of the same order.

Thus, life has been compared to a pilgrimage, to a drama, to a battle; Congress may be compared with the British Parliament. Paris has been compared to ancient Athens; it may be comparedwith modern London.

Compare to 是“把……比作”的意思。例如：

We compare him to a little tiger. 我们把他比作小老虎。
The last days before liberation are often compared to the darkness before the dawn. 将要解放的那些日子常常被比作黎明前的黑暗。

Compare ... with 是“把……和……比较”的意思。例如：

We must compare the present with the past. 我们要把现在和过去比较一下。
We compared the translation with the original. 我们把译文和原文比较了下。

从上面比较可以看出，compare with 侧重一个仔细的比较过程。有时，两者都可以互相代替。例如：

He compared London to (with) Paris. 他把伦敦比作巴黎。
London is large, compared to (with) Paris. 同巴黎比较而言，伦敦大些。

在表示“比不上”、“不能比”的意思时，用 compare with 和 compare to 都可以。例如：

My spoken English can't be compared with yours. 我的口语比不上你的。
The pen is not compared to that one. 这笔比不上那支。
