Question

---_________ will she stay here?

---For _________．

1. A.
   How soon, one hour and a half
2. B.
   How long, one and a half hours
3. C.
   How soon, one and half hours
4. D.
   How long, one hour and half

Answer 1

B
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。
