问题 Current demographic trends, such as the fall in the birth rate, should favor ______ economic growth in the long run.

选项 A、slow
B、quickened
C、speeded
D、accelerated

答案D

解析 四词均表速度的加快或减慢,但从整句意思来看应是加快速度,所以A不对,B. quicken加快,加速,不仅指动作在更短时间内完成,还表示动作完成得更富有生气:主要指加快步伐,因此它的宾语一般是pace或steps,C. speed急行,疾驶,促进,作“加快”讲时常用“speedup”;D.accelerate加速,促进,强调一件事情的运动、增长及速度加快或是某事发生的比预料的要早。所以D为答案。
