问题补充：
I got to the reading-room, I found that he there.
A. At every time; read
B. Each time; was reading
C. At each time; would read
D. Every time; reads
答案：
A. At every time; read
(答案→)B. Each time; was reading
C. At each time; would read
D. Every time; reads
解析： 考查连词和时态。两个简单句之间要用连词连接，所以排除A,C;主句I found时态是一般过去时，所以从句that he there用过去时态的某种形式，选B。
