老师讲：be made of 是一眼就能看出原材料的，是物理变化；
be made from是看不出原材料的，是化学变化。
《新概念英语》上说：be made of是用一种材料制成的
be made from是用多种材料制成的
哪一个是对的？？

老师讲的对
但是词的区别含义在牛津字典里都找的到各种资料可能都会有区别根据作者自己的观点语法也是一样考试要考的是老师的卷子当然听老师的

老师讲讲的是对的!

be made of 是物理变化；
be made from是化学变化。

be made of 是一眼就能看出原材料的，是物理变化；
be made from是看不出原材料的，是化学变化。

be made of 眼睛可看出原材料的
be made from 眼睛不可看出原材料的
The desk was made of wood.
The paper were made from wood.

2个都对，站的角度不同。
一种材料，也会发生化学变化的。多种材料不一定会发生变化。

应试的话，还是按照你老师的教法来做题目比较好。
