be made of和 be made from 的区别

be made of和 be made from 的区别

看出原材料要用be made of ,看不出原材料要用be made from,举个例子吧：
The shirt is made of silk.
This kind of wine is made from wheat.

用of 看得出原材料，from还不出原材料。

都是由什么组成 be made of 是可以看出原材料的,例:The sweater was made of woollen. 毛衣是羊毛作的(可以看出的) be made from是不可以看出原材料的,例/:The paper is made from wood 纸是树木作的(看不出来的)

be made of“由…构成”，能看出原材料,如： the desk is made of wood. the knife is made of metal.

be made from“由…构成、制成成品”，被制成的东西看不出原材料， 如：the paper is made from the wood

be made from是不可以看出原材料的,例/:The paper is made from wood 纸是树木作的(看不出来的) be made of be made from 由所组成；由造成

be made of和be made from都表示“由……制成”，主语为制成品。 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。如： The kite is made of paper．风筝是用纸做的。 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。如： The paper is made from wood．纸是木头做的。 Butter is made from milk．黄油是从牛奶中提炼出来的。
