be made of和be made from都可以表示“某物由什么制作而成”,但be made of指的是制作东西的原材料并未完全改变,仍可辨认,be made from指原材料已经完全改变,无法辨认。
例如:The box is made of wood.这箱子是木头做的;Wine is made from grapes.葡萄酒是由葡萄酿制的。
有这种区别的原因在于,of和from的区别。of有“属于...的,关于...的”意思,木头做成的箱子,从性质上来说,还是木头,或者至少还能看出来跟木头有关;from有“从...来”的意思,葡萄酒是用葡萄做的,但已经看不出来和葡萄有关,只能从酒的成分表里得知由葡萄制成。
