Question

---Who left the window _______?
--- Sorry. I forgot _______it when I left yesterday.

A．opened; to close

B．open; to close

C．open; closing

D．opening; closing

Answer 1

B

考查情景交际。“谁没有关窗户？”“对不起，昨天我离开时忘记关了。”open可以作形容词，意为“开着的”，表示状态。forget to do sth.“忘记要做某事”；forget doing sth.“忘记做过某事”。本题意思是“没关”，故用forget to do。故选B。
