— For .

A. How soon, one hour and a half

B. How long, one and a half hours

C. How soon, one and half hours

D. How long, one hour and half

答案：

A. How soon, one hour and a half

(答案→)B. How long, one and a half hours

C. How soon, one and half hours

D. How long, one hour and half

解析：how短语用法。how long多长（时间），对一段时间提问，how soon多久，对将来的时间提问。由答语for…判断指一段时间，故A、C错。一个半小时用one and a half hours

或one hour and a half，故选择B。
