问题补充：
---What should we do next?
--- The first thing is a hotel .
A. to find; to stay
B. to find; to stay in
C. find; staying
D. find; to stay
答案：
A. to find; to stay
(答案→)B. to find; to stay in
C. find; staying
D. find; to stay
解析：句意：下一步我们应该做什么？首先是找一个旅店住下。to find不定式表示结果，to stay in不定式做定语，修饰hotel,不定式作定语常后置，当动词是不及物动词时要带上相对应的介词，故选B
