I walked slowly through the market,where people（）all kinds of fruits and vegetables.I studied the prices carefully and bought what I needed.
A.sell B.were selling C.had sold D.have sold
此题正确答案是选B,此题强调的是 “我正在走着,看到了人们正在卖这些东西” 但是我不明白这句话用的为什么是过去进行时,而不是正在进行时?
那为什么不可以用”过去完成时“或”一般过去时“？

时态要前后呼应,主句用的过去式,所以不能用现在进行时态.
强调当时人们在卖各种蔬菜和水果
再问：那为什么不可以用”过去完成时“或”一般过去时“？
再答：你慢慢走过市场的时候，那时候人们正在卖各种蔬菜和水果。
你可以体会一下当时的语境。
如果用过去完成，说明动作先发生了，既然都卖完了，下一句就不能买到
一般过去时态，只是说明动作发生在过去，动作结束了。
楼主，你体会一下吧。
选择题一定要看上下文的语境，才可以更好的判定时态。
希望对你有帮助。
