Question

【题目】—Those people know how paper can be________ wood.

—They're pretty smart!

A. made in B. made from C. made of

Answer 1

【答案】B

【解析】

句意：—那些人知道纸张是如何由木材制作的。—他们真聪明！A项完整短语为be made in..意为“在某地制造”；B项完整短语为be made from意为“由…制造”通常成品中看不到原料；C项完整短语为be made of，意为“由…制造”，通常在成品中能看到原料。从纸张表面是看不出由木材制造的，故选B项。
