Question

【題目】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：她經(jīng)常在星期天洗衣服。但上星期天她沒洗衣服。often是一般現(xiàn)在時(shí)的標(biāo)志詞，主語是三單，動詞wash三單為washes，last Sunday是一般過去時(shí)的標(biāo)志詞，需要借助于助動詞did，否定句結(jié)構(gòu)為：主語+didn’t+動詞原形，根據(jù)題意，故選B。
