【问】 “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，70.3)

答案为A。但我认为D(to be cleaned)似乎也是正确的。

【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，75.5)(答案为C)

见need/require to be done，请与其中的试题作对比。
