Question

【题目】They ______ the chickens and ______ in the river on their last school trip.

A. feed；swim B. fed；swam C. feed；swam D. fed；swim

Answer 1

【答案】B

【解析】句意：在他们上次的学校旅行中他们喂了鸡，还在河里游泳。feed喂养；fed是feed的过去式；swim游泳；swam是swim的过去式。根据句意和句中的on their last school trip可知，这句话说的是过去的事情，这两个空是句中并列的谓语动词，都应用过去式，故应选B。
