wash 为什么不加es
答
1、2都填wash
答
都用wash,一空情态动词can后应加动词原形，二空是是固定搭配help sb do sth
答
help sb do sth 帮助某人做某事
答
不对！都是wash
help sb do 必须用原形！
答
help是个使役动词,它的宾补可以是省略to的do,或to do,但不能是does；而washes是谓语动词的形式,故错误.
答
原形就好，为什么要加es？
答
1.Can you help your father _wash___his car? 2.I can help your father _wash___his car.
1填wash,2填washes吗？
都填wash啊 help sb to do sth且to可以省略，所以这里是wash原型形式。
