Question

When I entered the step-classroom (階梯教室), the lecture __________ and the audience __________ attentively.

1. A.
   began, listened
2. B.
   was begun, was listening
3. C.
   had begun, listened
4. D.
   had begun, were listening

Answer 1

D
試題分析：考查時態(tài)，句意：當我進入階梯教室的時候，講座已經(jīng)開始了，觀眾正專心的聽。第一空填過去完成時，表示講座是在我進入前就開始了，第二空填過去進行時，表示我進去的時候觀眾正認真的聽。選D。
考點：考查時態(tài)
點評：考查時態(tài)題，如果有時間狀語，就充分利用時間狀語，如果沒有，要結(jié)合上下文找出來。這句話的When I entered the step-classroom就是明顯的暗示
