have sth to be done和have sth to do的区别

Question

have sth to be done和have sth to do有什么区别.

有人说是主动和被动的关系.

可是例句:l have some exams to be taken next week.

为什么要用被动.意思不应该是有一些考试去参加吗...

不是有一些考试去被参加...

为什么不是...

l have some exams to take next week.

还有一句例句.

Do you have some clothes to be washed?
为什么不是..
DO you have some clothes to wash?

请哪位高人给我准确详细的解释 ..

最好还附有例句哦 !!

have sth. to do表达某人要做某事,做事的人是主语 例如I have my work to do.
