Question

【题目】She often _____ her clothes on Sundays. But last Sunday she _____ her clothes. ( )

A.washed; didn’t washB.washes; didn’t washC.washes; didn’t washed

Answer 1

【答案】B

【解析】

句意：她经常在星期天洗衣服。但上星期天她没洗衣服。often是一般现在时的标志词，主语是三单，动词wash三单为washes，last Sunday是一般过去时的标志词，需要借助于助动词did，否定句结构为：主语+didn’t+动词原形，根据题意，故选B。
