问题
选择题
When they had cleaned their bowls in this way, they would sit __________ at the pot with eager eyes, as if they wanted to eat it.
A．stared
B．staring
C．to stare
D．stares
答案
B
题目分析：句意：当他们把5这样清理干净时，他们会坐下来用急切的眼神盯着罐子，好像要吃了它似得。A为过去分词形式，表被动完成，不符合语境。C为动词不定式，表目的，排除。-ing形式作状语表伴随，stare和主语是逻辑上的主谓关系，故选B。
考点: 考查非谓语的用法。
