Question

Paper produced every year is ________ the world’s production of vehicles.

A．the three times weight of	B．heavier three times than
C．as three times heavy as	D．three times the weight of

Answer 1

D

解析试题分析：句意，每年生产的纸张数量是世界车辆生产重量的3倍。这里使用的是倍数的表达：“A is倍数+the weight of B”(A是B的几倍重)，这是固定用法，故选D。
考点：考查倍数的表达。
