She sat near the window and asked questions about everything she saw. Suddenly, a middle-aged lady (中年妇女) got on the train and sat next to Sally. “Hello, little girl.” She said. Sally did not answer, but looked at her curiously(好奇的). The lady was wearing a blue coat and a large, funny hat. After the train started, the lady opened her handbag(手提包) and took out her powder compact(粉盒). She then began to make up her face. “Why are you doing that ” Sally asked. “To make me beautiful,” the lady answered. She put away her compact and smiled. “But you are still ugly (a).” Sally said. Sally was amused(感到有趣的), but I was very embarrassed(尴尬的)!

【答案】B
【分析】A、根据铁钉生锈的条件进行分析；
B、根据环境中有食盐水或酸存在，氧气含量减少的较多进行分析；
C、根据随着反应的进行，氧气浓度减小，温度升高进行分析；
D、根据铁生锈消耗氧气，气体减少，压强减小，铁生锈放热，温度升高，压强增大进行分析。
【解答】解：A、对比图1的①③和②③可知，铁钉只与干燥的空气或只与水接触，氧气含量几乎不变，而铁钉与空气和水同时接触，氧气含量减少，则说明铁钉生锈需要水和空气共同作用，故A正确；
B、通过图1的③④⑤可知，环境中有食盐水或酸存在，氧气含量减少的较多，说明环境中有食盐水或酸存在，会加快铁生锈的速率，故B错误；
