选择题
----- Where did you ______ our chemistry teacher?
----- It was in the supermarket ______ I saw him.
A．come to, where
B．come across, that
C．come across, where
D．come to, that
答案
答案：B
第一空考查短语辨析，come to 达到，come across 偶然遇见，第二空考查强调句型，强调的是地点状语in the supermarket，that 为强调句型的标志。句意：你在哪偶然遇见了我们的化学老师？就是在超市我遇见了他。所以选B。
