核心问题
某大学选拔教师出国留学英语考试题。The idea for the new machine came to Mr. Lane ____ to work last week. A. as he drives B. while has driving C. when he has driven D. while driving 我认为这道考题本身有毛病。不知您的看法如何？
词典解答
这道考题虽然选自美国出版的 Six Practice TOEFL Tests (Arco Publishing Company, Inc. New York, p. 83), 但是, 我们认为, 在这里选任何一项都是错误的。标准答案规定选 D, 然而选 D, 分词 driving 的逻辑主语与句子的语法主语 the idea 不一致, 犯了语法错误。托福考试中多次反复出现的一道改错题可以证明我们的说法是正确的:
A few years ago, travelling through Italy, the idea of history of Florentine architecture
occurred to him. (TOEFL) (应改为: when he was travelling)
(参见下条)
