问题 After some time the second stage of the space shuttle, having used up its fuel, just like the booster, separates and______.
选项 A、runs away
B、charges for
C、falls off
D、merges into
答案C
解析 本题意为“过了一些时候，航天飞机的第二级由于用光了燃料，就像助推器，脱开然后落下。”fall off的意思是“下降，跌落”；ran away的意思是“潜逃，私奔，失去控制”；charge for的意思是“收费，要价”；merges into的意思是“合并成”。根据题意，只有C项为正确答案。
