【解析】试题分析：本文结合美国科学家Carole Palmer的研究，认为人吃糖的方式影响牙齿的健康，应该改变自己的一些生活习惯。
【1】句意：你吃得快还是慢慢享受？有什么区别吗？不定冠词a后接单数名词；eat it quickly 和enjoy it slowly相反，根据句意语境和首字母提示，可知填difference。
【2】句意：如果一个人吃太多糖，他或她的牙齿会非常糟糕。his or her，形容词性物主代词，后接名词；tooth牙齿，常用其复数形式teeth。根据句意语境和首字母提示，可知填teeth。
【3】句意：有些人可能吃糖很快，其他人可能慢慢品尝。some…others一些……，另一些……，表示不确定，此时others和some同义。根据句意语境和首字母提示，可知填others。
【4】句意：事实上，一些科学家发现，你吃糖的方式影响牙齿的健康。本句是宾语从句但结构复杂，从句主语由how you eat sugar这个句子充当，从句缺谓语动词，根据主句时态（found是过去式）和首字母提示，可知填affected。
【5】句意：她说糖在牙齿上消耗的时间越多，对你的健康就越有害。spend time on sth. 花时间在某物上；sugar糖，不可数名词，是单数第三人称，动词需用三单形式。根据句意语境和首字母提示，可知填spends。
【6】句意：例如，如果你在几分钟内喝了一瓶苏打水，而不是慢慢地喝上几个小时，那么你的牙齿就不会那么危险了。instead of（是…）而不是…，固定短语，后接动名词形式；根据句意语境和首字母提示，可知填instead。
【7】句意：所以，如果你想拥有健康的牙齿，你应该改变你的一些习惯。teeth牙齿，名词需用形容词修饰。根据下文Because sugar is bad for your health, anyway, you should just eat less of it.，结合句意语境和首字母提示，可知填healthy。
