my watch doesn't work.i must have my brother[------]it 为什么写repair

问题描述:

my watch doesn't work.i must have my brother[------]it 为什么写repair

您好!
my watch doesn't work.i must have my brother[------]it 为什么写repair
这里是考察一个固定短语
have sb do sth,表示让某人做某事,所以后面是动词原形哦
另外补充:后面的句子也等于
I must have it repaired by my brother这里是have sth done表示让某物被做,这里是让我们手表被我的哥哥修
祝你学习进步O(∩_∩)O哈!my watch doesn't work.i must have my brother[------]it 为什么写repair这里不可以写repaired 对吗?这里是have sb do sth是吗?have sth done是用于其他句子吗?你好!这里不可以是repaired,因为have 后面的是my brother是个人,而如果像我说的have 后面是my watch,那么就是被修了,所以用被动repaired
