核心问题
“My watch has been losing time for the past week.” “It probably needs ____.” A. cleaning B. to clean C. cleaned D. to be cleaned (TOEFL, 70.10) 答案为 A。但我认为 D (to be cleaned) 似乎也是正确的。
词典解答
这道题作为语法结构试题是不恰当的。因为这里有两个同样正确的答案。此题很明显地与下列托福试题相矛盾： The coffee is very cold, it needs ____. A. hot B. to be heating C. to be heated D. to be hotted(TOEFL)(答案为C) 见 need/require to be done, 请与其中的试题作对比。
