问题描述：
On Sundays he sometimes ______his clothes and sometimes ______ some shopping.A.Wash; do.B.is washing ; is doing.C.Washes; do.D.Washes ; does.为什么sunday后面有s?and前面和后面的动词需要保持一致吗?还是不管前面的动词是什么形态的,后面的动词要保持原型?
答
D
sometimes 有时,常一般现在时连用,主语是三单,故WASH 要加ES,DO 要用DOES ,因为AND 连接的两个动词要一至,另外,SUNDAYS 指所有的星期天
加油!不明白再问!
