Question

Books are made________paper while paper is mainly made________wood.

A. of ; of B. from ; from

C. of ; from D. from ; of

 

Answer 1

C

【解析】

试题分析：句意：书是用纸制成的，然而纸主要是用木头制成的。两个单词都是由……构成的意思． 第一个be made of是指不经过加工，能直接看出原材料，例如桌子是由木头做成的，The desk is made of wood.

第二个be made from是指经过加工，不能直接看出原料．例如书本是由木头做的．The book is made from wood.结合句意，故选C

考点：考查make短语。
