6（）
A.heading
B.preceding
C.choosing
D.traveling
参考答案：A
解析：
本题与上一题同出现在一个句子中…but unfortunately the trend in today’s youth is ______the opposite way，前半句说“如果世界充满了乐观，那它将更加美好”，后半句的转折词but含义是年轻人的所为与前面说的相反，其中trend“趋势”一词给我们以很大启发，说明空白处填入的词需要含有“朝……，向……”的意思。综观[A]、[C]、[D]，乍一看似乎都可以，但能与trend一词意思呼应，并能确切符合题句意思的只有heading，因此是正确选项。[B]preceding意为“在……前面”，明显不符合句意要求。
