don't konw what to do about it don't konw how to do about it

don't konw what to do about it don't konw how to do about it I really don't konw how to do about it I don't konw what to do.=I don't konw how to do it .为什么what不 don`t konw what to do.. i don’t konw ().B.what to do C.how to do it 我觉得两个都选,这道题好奇怪.. 为什么不能在konw后面直接加not 比如i don't konw how to do it. But they don't konw what to do I don't konw what to “if you don't want others to know about it ,don't do it. i want to make friends with him ,but i don't konw what to do It\'s my fault! I\'m sorry!But I don\'t konw what could do!是 god,i don t konw how to do 是那首英文歌曲里的
