she helped her mother cook dinner yesterday.
问题描述:
she helped her mother cook dinner yesterday.
劳烦您讲解下这句的句子成分.
2:为什么cook不用过去式,
第一个讲解明白的,马上就给分.
有没有这样的句子,谓语用过去式,宾补动词还用过去式?
答
she是主语 helped是谓语 her mother是宾语 cook dinner 是宾语补足语 yesterday是时间状语
因为help sb do sth 所以这里cook用动词原形
没有 只有过去分词形式
一般情况下,过去式表示主动的动作,而过去分词表示被动含义劳烦您,举个例子,谢谢比如he has his bicycle repaired.
