题目内容：

I think this box is made of( )

优质解答

这道题的正确答案是：
I think this box is made of (paper或wood).
翻译为：我认为这个箱子是用纸（或木头）做成的.
be made of 能看到原材料
be make from 看到不到原材料
这里用的是is made of,也就是说组成这个箱子的材料是能看到原材料的
所以填写paper或wood.
Everything there is made of bamboo.
那里所有的东西都是竹子做的.
The bed is made of wood.
床是木头做成的.
如果用is made from,就代表看不到原材料
给你一些例句：
The clothes are made from cotton.
这些衣服是棉花做成的.
The paper is made from wood.
纸是木头做成的.
