After a long walk, most of us are so tired and ____ that we fall _____ quickly on the grass.

A. sleepy; asleep

B. sleepy; sleepy

C. asleep; sleepy

D. asleep; asleep

【答案】

A

【解析】

句意：走了很长路后，我们大多数人如此疲倦和困乏以致于我们很快在草地上睡着了。sleepy“困乏的，想睡的”，作表语，也可作前置定语；asleep“睡着的”，强调状态，作表语，或后置定语，fall asleep入睡。第一空表示困乏的，故用形容词sleepy，故选A。
