Though it is 30 years we last met I still remember the scene we got separated on a rainy

问题补充：

Though it is 30 years we last met, I still remember the scene we got separated on a rainy day.

A. since; where

B. before; which

C. since; when

D. before; where

答案：

(答案→)A. since; where

B. before; which

C. since; when

D. before; where

解析：考查固定句式和定语从句，第一空填since，是句型：It is+一段时间+since…”自从…以来有多久了”, 第二空填where，这是一个定语从句，先行词是the scene，定语从句中缺少地点状语，用where引导定语从句。句意：虽然我们有30年没见面了，我还记得我们在雨天分手的场景。选A。
