问题补充：

The pen I I is on my desk, right under my nose.

A. think...lost

B. thought...had lost

C. think...had lost

D. thought...have lost

答案：

A. think...lost

(答案→)B. thought...had lost

C. think...had lost

D. thought...have lost

解析：考查时态：语境为：我原以为丢了的确在鼻子底下。可知是过去以为，所以第一空填thought，而丢失这个动作是发生在thought前，用过去完成时：had lost，选B。
