【经典考例】—May I have a look at your plan for the robot competition, Smith?
—Sorry, Mrs. Brown. I've ______ it at home.
A.missed
B.forgotten
C.left
D.lost

C
解析：考查动词辨析。“leave sth. +地点”表示“把某物落在某地”，是固定搭配。A项“missed”意为“错过”；B项“forgotten”表示“忘记”，其后一般不接地点状语；D项“lost”意为“丢失”。根据句意“我把它落在家里了”，应用“left”，故选C。

【经典考例】—I'm sorry I ______ my exercise book at home this morning.
—It doesn't matter. Don't forget ______ it here this afternoon.

A.left；to take
B.forgot；bringing
C.left；to bring
D.forgot；to bring

C
【解析】考查动词辨析和非谓语动词。句意为：“对不起,今天早上我把我的练习本落在家里了。”“没关系。今天下午不要忘了带来。”forget sth. 忘记某事(物),没有忘记带的意思,只是遗忘,不记得某件事的意思；leave sth. at some place 把某物落在某地(忘在某地),指忘记带；take 带去；bring 带来；“forget + to do”忘记去做某事(未做)；“forget + doing”忘记了已做的某事(已做),故选C。
