Question

—       will she stay here?
— 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

Answer 1

B

how短語用法。how long多長（時間），對一段時間提問，how soon多久，對將來的時間提問。由答語for…判斷指一段時間，故A、C錯。一個半小時用one and a half hours
或one hour and a half，故選擇B。
