题目内容
16．-I called you this morning，but you were not in．-Oh，I ______ in the library．（ ）
| A． | am reading | B． | was reading | C． | have read | D． | had read |
分析 我今天上午打电话给你，但你不在家．哦，我当时在图书馆看书呢．
解答 答案：B 本题考查的是过去进行时态的用法．A现在进行时态；B过去进行时态；C现在完成时态；D过去完成时态．题干中上一句表示动作的时间发生在过去时间点（几天早上），不能与完成时态连用．故选B．
点评 过去进行时态表示过去某个时间正在发生的动作．解题时，要注意有时参照时间不是直接给出的，而是暗含在语境中．如本题，参照时间是：你上午给我打电话时．
