This desk is made___wood, and this kind of paper is made___wood, too.
A.from,of B.of,from C.of,of D.from,from
答案:选择B,be made of 和 be made from 都表示“由....制作而成”的意思。但是be made of可以看出原材料,属于物理变化,be made from不可以看出原材料,属于化学变化。此题中,desk 由木头制作而成,木头,我们可以通过肉眼观察。而paper由木块制作而成,paper,是纸张的意思,所以我们不能看出纸张的原材料。希望对你的学习有所帮助。加油,你是最棒的!
