A. fewer, more
B. little, many
C. more, less
D. less, more
答案：
A. fewer, more
B. little, many
C. more, less
(答案→)D. less, more
解析：fewer更少的，修饰可数名词复数；little很少，几乎没有，修饰不可数名词； many许多的，修饰可数名词复数；more更多的，修饰可数名词复数或者不可数名词；less，little的比较级，更少的，修饰不可数名词。句意：你认为在将来人们会有更少的工作吗？——我这么认为。并且我认为会有更多的机会旅行。结合语境可知本题中表示的是将来和现在的对比，故用形容词的比较级，选D。
