问题补充：
Wewalk in the moonlight, talking aboutwe were interested in.
A. used to; all what
B. were used to; all that
C. used to; what
D. were used to; what
答案：
A. used to; all what
B. were used to; all that
(答案→)C. used to; what
D. were used to; what
解析：考查固定短语和从句辨析。Used to do sth过去常常做某事，be used to doing sth习惯于做某事，all that引导的是一个all作先行词，that作关系词的定语从句，all that也相当于what，all不与what连用，排除A；句意：我们沟渠常常在月光里散步，谈论着我们感兴趣的东西。根据walk可排除B、D；故选C。
