Question

【题目】一___________ do your parents take exercise, William?—Less than three times a week.
A.How long
B.How much
C.How soon
D.How often

Answer 1

【答案】D
【解析】句意：— William，你的父母多久做一次锻炼？ How often 译为为多久一次，how long 是多久了，是对时间段提问，how much 可以对不可数名词数量进行提问，译为多少，how soon 多久才，对一般将来时进行提问。结合句意可知how often 符合语境，故选D。
