Question

The bed ____wood ____three separate parts.

A. is made from; is made up of   B. made by; is made with

C.made of; is made of    D. is made up of; is made by

Answer 1

C

解析:

區別be made of 與be made up of。前者意為“用……制成的”；后者是“由……組合而成”。從句子結構分析，名詞bed后的是定語，應用過去分詞短語，句子的主謂是被動關系，意為“由三個部分組成”，故用is made up of。
