问题描述：
a friend of my father's is repaireing it 如何改为被动语态?
为什么是it is being repaired by a friend of my father's.
其中being repaired 为什么不是is repaired 或者 是be repaired
答
首先,改成被动语态是：It is repaired by a friend of my father's其次,改成现在进行时,需要把动词变成ing形式,前面加上be动词,那么句中的动词实际就是is,把它变成ing形式就成了being,前面再加上be动词就成了is bein...为什么改为被动语态之后动词实际就是is 而不是repaired？语法这么规定的
