英语动词的变化,
问题描述：
英语动词的变化,
in many ways my disability has helped me grow stronger psychologically and become more independent.这里become 为什么用原形,而不用过去式呢?
答
become-became-become
这是过去分词
has+过去分词,完成时
and连接两个并列主语
helped是过去分词
所以become用过去分词
（become和helped都是谓语,才并列）如：ilikedplayingsoccerandplayingthepiano.like加to do或doing前面的用doing后面的也是doing平行指and链接同样的句子成分望采纳可追问平行是完全相同可以说是，谓语对谓语状语对状语。。。。。。。
