专题:

be made of与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、The desk is made of wood.(译文:桌子由木材做成。)

解析:桌子做成后还是可以看见木材,所以用be made of。

2、These cakes are made from sugar, butter and water.(译文:蛋糕由糖、黄油和水做成。)

解析:蛋糕做成后看不见糖粉,黄油或者水,所以用be made from。

1、“be made of”表示制成成品后,仍可看出原材料是什么,保留原材料的质和形状,制作过程仅发生物理变化。

2、“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。
