Question

—Lily, can you tell me______?

—I always exercise twice a week.

A.how often do you exercise B.how often you exercise

C.how often did you exercise D.how often you exercised

Answer

B

【解析】

句意：——莉莉，你能告诉我你多久锻炼一次吗？ ——我总是一周锻炼两次。

考查宾语从句语序和时态。how often do you exercise疑问语序+一般现在时；how often you exercise陈述语序+一般现在时；how often did you exercise疑问语序+一般过去时；how often you exercised陈述语序+一般过去时。根据can you tell me…可知后面接宾语从句，宾语从句用陈述语序，排除A和C；根据I always exercise可知，时态是一般现在时，排除D。故选B。
