单选题 Once lost ______.
  • [A] it is hard to get such a chance again
  • [B] to get such a chance will be difficult
  • [C] one can never get such a chance again
  • [D] such a chance might never come again


【正确答案】 D
【答案解析】[考点] 过去分同作状语
[解析] Once lost在这里是过去分词作状语，表“被丢失”，lost的主语应与后句的主语相一致，都是such a chance，将前句补充完整就是once such a chance is lost。
