选择题
---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
答案
答案: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。
