be made of和be made from有什么区别

be made of和be made from都表示“由...构成”。区别在于：
be made of“由…构成”，能看出原材料。
be made from“由…构成、制成成品”，被制成的东西看不出原材料。
例句：
The taps appeared to be made of solid gold.
水龙头似乎是用纯金制成的。
I wonder if wine can be made from cherries.
我很好奇樱桃是否可以做酒。

be made of “由……制成”，看得出原材料。
be made from“由……制成”，看不出原材料。
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.

意思都是：由什么组成的。
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)本回答被提问者采纳

be made of与be made from都是由。。制成的意思
be made of制成后还能看出原材料是什么
be made from则是看不出原料是什么
