As any younger brother will tell you, having a big brother involves a lot of walking in someone else’s shadow, especially when you have a brother who is a typical example of “cool”. For years I wanted to do everything my elder brother Tyson did, but no matter how hard I tried, I was always the neglected (被忽略的) one. My legs just weren’t made to run like his. I could never play football or basketball well.
I probably would have continued trying to keep up with him for the rest of my high school career, but when my family moved, everything changed. Tyson left for college, so I had to start at a new school all by myself. This new start gave me an opportunity to redefine myself and discover an entirely new version of “cool”.
I don’t know what made me decide to try some new activities at the new school, but one day I chanced to show up for an after-school meeting of the Science Olympiad team. I had always been fascinated with chemistry, biology, and math, but since those interests hadn’t fit Tyson’s definition of “cool”, I had never pursued them. On this day, for some reason, I did.
As we organized teams, prepared resources and practiced answering questions, I felt more connected than I ever had to any sports team. I didn’t feel as though I needed to keep up with anybody else; I was finally with peers who understood me. It was so good to feel accepted for what I’m good at. For the first time in my life, I actually felt cool. Now I know who I am! I’m Tyson’s little brother, but that’s only part of my identity. I’m a cool guy in my own way, too. I’m relieved to know that “cool” has a much broader definition than what I used to think.

【分析】磷燃烧能够消耗空气中的氧气，氧气消耗后，容器中的气压减小，在外界大气压作用下，容器内体积减小，减少的体积即为容器中空气中的氧气体积，进一步可以计算出空气中氧气的含量。
【解答】解：①铜粉的用量多少会影响实验结果，即铜不足时导致实验结果偏小，该选项说法正确；
②实验结束后冷却到室温才能读数，该选项说法正确；
③气球的作用是调节气压并使氧气完全反应，该选项说法正确；
④在正常操作情况下，反应消耗氧气的体积应该约占反应前装置（注射器、玻璃管、气球）内气体体积的，该选项说法不正确。故选：D。
18．选C
19．答案：C 解析：①：Mg 粉燃烧发光，氧烛使用时可能有照明功能，①正确。②：NaClO3分解（类似KClO3分解，属于分解反应 ），Mg 粉燃烧（化合反应 ），②正确。③：催化剂在反应前后质量不变，并非原物质质量均减少，③错误。④：Mg 粉过少，无法提供足够热量使\(\ce{NaClO_{3}}\)分解，反应难持续；过多则消耗氧气，减少产氧量，④正确。
