回答：Holiday flights are getting _________expensive the students want to travel to Egypt this summer holidays. 
A. more B. more and more C. less D. less and less 
答案:D
译文:假期航班越来越便宜了,学生们想要在今年的暑假去埃及旅游.
解析:从前一句子的时态are getting (现在进行时),可以看出是一个逐步变化的过程,所以要用 比较级+and 比较级, 表示逐步变化,"越来越..." , 从后一个句子学生们想要在今年的暑假去埃及旅游可以看出应该价格是便宜了,所以学生才担负得起这费用,所以用less and less .
