(单选题)
You’d better do exercise at least twice a week ______ you can keep healthy.
A.so that
B.only if
C.as through
D.in case
参考答案:A
参考解析:
考查so that引导的结果状语从句。句意:你最好一周至少做两次运动,这样才能保持健康。so that意为“以至于,以便”,引导结果状语从句;only if意为“只有”,引导条件状语从句;as through意为“即使”,引导让步状语从句;in case意为“万一”,引导条件状语从句。结合句意,此处是指通过锻炼才能保持健康,为结果状语从句。故选A。
