Question

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

Answer 1

B

解析試題分析：句意：當他們把5這樣清理干凈時，他們會坐下來用急切的眼神盯著罐子，好像要吃了它似得。A為過去分詞形式，表被動完成，不符合語境。C為動詞不定式，表目的，排除。-ing形式作狀語表伴隨，stare和主語是邏輯上的主謂關(guān)系，故選B。 
考點: 考查非謂語的用法。
