be made of和be made from的区别

Be made of和be made from都表示“由...制成”。主语为制成物，be made of表示制成成品后。Be made from表示在成品中已经无法辨认。例如：only the rough guess and estimate can be made of it。对此只能做出一个粗略的测算。 

1、be made of和be made from都表示“由……制成”，主语为制成品。

3、be made from 表示制成的东西完全失去了原材料的外形或特征，或原材料在制作过程中发生化学变化，在成品中已无法辨认。

4、be made with 指“制作中用了什么东西”，be made with 还可用于抽象意义。多指用声明工具。

5.be made up of 由……制出的,组成”。与 be made of, be made from 意思类似：Our class is made up of six groups. 我们班由六个小组组成。
