解析
【分析】
这是一篇细节类英语阅读理解题，解题思路非常清晰：首先先通读题干划出每道题的核心关键词，再带着关键词回到短文中定位对应的原文内容，所有题目的答案都能在原文中找到明确依据，不需要额外拓展脑补，逐一比对选项和原文内容就能选出正确答案。做题时按照题目顺序逐题找对应段落，就能避免漏看关键信息。
【解析】
1. 定位原文第一段前两句"Anna feels bad these days. She has a toothache."，直接说明Anna不舒服的原因是牙疼，A选项是她需要改正的行为、B选项是牙医给她的建议，都不是不舒服的原因，因此选C。
2. 定位原文第二段"The sugar(糖) stays on the teeth and makes them dirty. Then it causes tooth decay(蛀牙). That really hurts."，可以看出吃糖后最先发生的是糖附着在牙齿上，之后才会形成蛀牙、产生痛感，因此最先发生的事件是B选项。
3. 定位原文第三段牙医的建议"She should brush her teeth every morning and night, especially(尤其) before bedtime."，明确说明Anna需要早晚都刷牙，因此选B。
4. 定位原文第三段"Also, she should eat more vegetables to help her teeth get strong."，直接说明多吃蔬菜可以让牙齿变得坚固，因此选B。
5. 结合原文内容，Anna现在已经因为蛀牙牙疼，如果不改变坏习惯，蛀牙会越来越严重，牙齿会疼得更厉害，B选项牙齿变白、C选项牙齿变坚固都不符合逻辑，因此选A。
