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(shí)態(tài)，句意：當(dāng)我進(jìn)入階梯教室的時(shí)候，講座已經(jīng)開(kāi)始了，觀眾正專心的聽(tīng)。第一空填過(guò)去完成時(shí)，表示講座是在我進(jìn)入前就開(kāi)始了，第二空填過(guò)去進(jìn)行時(shí)，表示我進(jìn)去的時(shí)候觀眾正認(rèn)真的聽(tīng)。選D。
考點(diǎn)：考查時(shí)態(tài)
點(diǎn)評(píng)：考查時(shí)態(tài)題，如果有時(shí)間狀語(yǔ)，就充分利用時(shí)間狀語(yǔ)，如果沒(méi)有，要結(jié)合上下文找出來(lái)。這句話的When I entered the step-classroom就是明顯的暗示
