问题
选择题
Though it's a challenging job, 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
答案：D
题目分析：考查倍数：倍数+the+名词，one-third就是倍数，the time是名词，it took me是定语从句，修饰time，句意;虽然这是有挑战的工作，但他用了我花的三分之一的钱。选D。
点评：本题考查倍数的表达：除了用倍数+as +adj+as，还有：倍数+比较级+than，倍数+the+名词+of，倍数+从句，这题的倍数是one-third，做题时按照句子的结构来选择。
