Ⅰ.单项填空
1.-Can those________at the back of the classroom hear me?
-No problem.
A.seat B.sit C.seated D.sat
答案 C
解析 "________at the back of the classroom"为分词短语作定语。sit为不及物动词,可用sitting...作定语;seat为及物动词,常与反身代词连用或用be seated形式。这里seat 与those构成逻辑上的动宾关系,故用其过去分词作定语。
2.We finished the run in less than half the time ________.
A.allowing B.to allow
C.allowed D.allows
答案 C
解析 句意为:我们用了不到被允许的时间的一半就跑完了。time后缺少定语,"时间"与"允许"之间是被动关系,因此用过去分词形式。
3.Please remain ________;the winner of the prize will be announced soon.
A.seating B.seated
C.to seat D.to be seated
答案 B
解析 句意为:请在座位上坐着;很快就会宣布获奖者。seat是及物动词,remain/be seated保持坐着的状态,坐着。
4.The trees ________ in the storm have been moved off the road.
A.being blown down B.blown down
C.blowing down D.to blow down
答案 B
