23、一名“ 的习惯用法。6D 序数词和名词共同构成的专有名词还可以是 thc Second World War 的形式。7C 只有 C 项为正确的表达方式，或者也可以写成“one or two days“再如：one hour and a half 或 one and a half hours8B “in half“表示“ 分成一样大小的两半 “。也可以说“cutin two“9B 再如 twice the height(depth，width，weight，etc)of10D eitheror连接主语用就近原则。be to hand out the prizes 意为“要颁发奖品“ 。11答案为
