Mrs.Green wants one and ____ of apples and ____ of oranges. A.a half kilo；a half kilo B.half a kilo；a half kilos C.a half kilos；half a kilo D.half a kilo；half a kilo (顺便说一下有什么区别)
选C one and a half表示一个半，大于一 所以其后加名词复数，如 one and a half kilos 楼上说的对one and a half+n=one+n+a half half a kilo,意为半斤 一半小于一，所以kilo用单数 类似的有 one and a half hours=one hour and a half,意为一个半小时 haf a hour，意为半个小时
