单选题 Fewer and fewer of today's workers expect to spend their working lives in the same field, not to {{U}}mention{{/U}} the same company.
  • A. all else
  • B. much worse
  • C. less likely
  • D. let alone
【正确答案】 D
【答案解析】[解析] let alone意思是更不必说，The baby can't even walk, let alone run.婴儿连走都不会，更别说跑了。all else“所有其他的”；much worse“糟糕得多”；less likely“较少可能”，此三项选择都与本题不符。
