compared to与compared with的区别

compare with 的意思是：与…比较,compare to 的意思是：比喻为
compare...with...把……和……比较(常表示同类相比,比较)
compare...to...把……比作……(常表示异类相比,比喻)
1.Let'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.
2.The heart is often compared to a pump.心脏常被比作水泵.
二者相同的地方在于：compare的过去分词短语形式用作状语时,不管同类还是异类,compared with和compared to都可以用.例：
Compared with/to western countries,China uses materials very carefully.和西方相比,中国使用物资很节省.
