问题 In recent years, railroads have been combining with each other, merging into super-systems, causing ______ concerns about monopoly.
选项 A、enhanced
B、curbed
C、disrupted
D、heightened
答案D
解析 近形近义题。铁路部门之间纷纷合并形成超级体系，因此人们对垄断的关注应该是不断升高，因此答案选[D]heightened意为“(使)提高，(使)加强”。易错选的是[A]enhanced“提高，增加”，指在价值、美、声望上增强，常用作褒义；[B]curbed“抑制，控制”；[C]disrupted“干扰，打断”。
