He has been there for__ A.two and a haif hours B.two and a half months c.two and haif a month
语法上看.A和B都对,但就习惯来说,B可能更合逻辑.
另：A中的haif拼错了,应该是half,如果这也算错的话,那就是B啦~ 再问： month加了S和没加S有什么区别？half是我打错了。。。。呵呵
再答： month加S当然是表示复数了，这儿的 num+a half 后接month/hour等都必须用复数 你可以说，a/one month，但你必须说 two and a half months，因为2个半是复数的啊~
