答案A

解析 本题测试特殊疑问句的用法。“How soon...?”问的是大概时间:要用多久?例如:How soon will you come back from your vacation? In about one month.(你多久度假回来?大概一个月后。)“How long...?”问的是具体时间;要用多长时间?例如:How long will it take you to get to school from home? About 40 minutes.(从家到学校大概要花你多长时间?大概 40分钟。)“How often...?”问的是频率:多久一次?例如:How often do you go swimming? Twice a week.(你多久游一次泳?一周两次。)“How fast...?”问的是速度:多快?例如:How fast do you often drive your car? At a speed of 60 miles per hour. (你通常开车有多快?一小时60迈。)本句的意思是:“你多久能完成作业?半个小时后。”因此,A为正确答案。
