be made of 和 be made from的区别我知道be made of和be made from都是制成的意思~但是好像还有什么区别.是看制作的材料来区分、谁能给解释一下,然后在写几个例句

be made of和be made from后面都加原料
但是be made from接的是不能看出原材料的
e.g: The paper is made of wood.
而be made of接的是看得出原材料的
e.g：The cup is made of glass.

be made of 可以看出原材料。(物理变化)e.g:The table is made of wood.
be made from则看不出原材料。(化学变化）e.g:Paper is made from wood

be made of 可以看出原材料。
This desk is made of wood .
This bottle is made of glass .
be made from则看不出原材料。
This kind of wine is made from grapes .
Paper is made from wood .

看出材料的用of,this chair is made of wood.
看不出的用from, paper is made from wood

be made of 可以看出原材料
be made from不能看出原材料
eg：The desk is made of wood.(肉眼可以看出桌子是用木材制的)
The oil is made from peanuts.（肉眼看不出花生油的原材料）
