5．It will take you _______ to do your homework．（ ）| A． | a half hour | B． | half an hour | C． | hour a half | D． | half hour |
分析 做作业将花费你半个小时的时间．．
解答 答案：B．考查量词．句意"做作业将花费你半个小时的时间．"hour a half、half hour本身不对，所以C、D不正确，a half hour语法没错，但习惯上几乎没有人这么用，半小时固定表达为half an hour．故选B．
点评 注意量词搭配使用，以及半小时的固定表达方式，依照内容进行合理的判断．
