As we know, paper is made wood , that is to say wood is made paper.
A. of, from
B. in, into
C. from, into
D. from, by

A. of, fromB. in, into(答案→)C. from, intoD. from, by解析：1、be made of 表示制成成品后，仍可看出原材料是什么，保留原材料的质和形状，制作过程仅发生物理变化。 2.be made from 表示制成的东西完全失去了原材料的外形或特征，或原材料在制作过程中发生化学变化，在成品中已无法辨认。 3、be made into表示制成什么，后面接制成后的物品。4、be made by表示由谁制成，后面接人。根据题意，纸是由木材制成，那就是说木头要制成纸，所以选C。

这个解释是对的
