46、试题解析】 主旨大意题。文章开篇第 1句话就是整篇文章的主题句，接下来的各段内容都是围绕此主题 展开的， C与之意思相符。故选 C。本题最具干扰性的是 D，事实上，该选项中的 troublesome意为 “烦人的 ”，而不是 “陷入麻烦的 ”，因此不能用该词形容文中的乘客，故排除 D。 【知识模块】 阅读 【知识模块】 阅读 11 【正确答案】 C 【试题解析】 事实细节题。只要知道第 1段第 2句中的关键词 accelerate意为speed up“加速，加快 ”，就可以排除其他选项。 【知识模块】 阅读 12 【正确答案】 B 【试题解析】 事实细节题。本题考查对比处。作者在第 1段第 5
