I couldn't understand why you did it like that way?这里面 I 是主语,情态动词_英语解答

I couldn't understand why you did it like that way?
这里面 I 是主语,情态动词的否定加上动词understand ,那 why you did it like that way 算什么成分?
还有一个问题就是 find 和believe是系动词还是别的什么动词？

i 主语 understand 谓语 why you did it like that way 宾语从句 find believe 是实义动词
