一道英语选择题,请说明原因
He did it ______it took me.
A.one-third a time B.one-third time
C.the one-third time D.one-third the time

答案

one—third the time
原因：
He did it one-third the time it took me 的英语结构是：He did it for one-third the time it took me .英语中省略for 到处可见,the time it took me中it took me 是定语从句,意思是：它（那件事）所花费9我的时间),把“the time "放到正确位置是“ it took me the time "(这件事占据我那一段时间）先行词the time 在定语从句中作直接宾语.因此 He did it one-third the time it took me 这句话的直译意思是：他当时做那件事用了三分之一的（the time )那段特定的时间,那件事花费我(正是)那段特定的时间..one—third the time 是三分之一的那段时间,指的不是那段时间的全部.如果写成 “the one -third time”指的 是“特定的三分之一的时间”表示“整体上上讲就是三分之一的时间”,这时我们对三分之一的时间概念一定模糊不清,故英译中表示 “三分之一的.（特定的整体）时间”或“.的时间的三分之一”,很明显用“one-third the time ”就很合乎语法和逻辑理解了.例如 we played basketball that day for six hours ,(我们那天打篮球用了6小时）,那么,one-third the time we played basketball that day for is two hours ,(三分之一的我们打篮球的时间）或我们打篮球的三分之一的时间是2小时.）,从这里看看“for"是不是很别扭,把它一省略,就更能明白了,.
因为"the "表示特指,the time it took me 是定语从句修饰先行词"the time " ,（见上面分析）,定语从句的先行词前加"the"是理所当然的事.a 表示泛指.
