【分析】
本题为语篇型语法填空，需结合语境、语法规则及固定搭配完成。解题思路：1. 分析每个空的句子成分，判断所需词性/形式；2. 结合所给单词或上下文逻辑，确定正确形式：如序数词、形容词转换、名词复数、主谓一致、比较级、连词、介词、不定式、人称代词宾格等。
【解析】
1. 句意：正确饮食是第一步。此处表“第一”，用one的序数词形式first。
2. 句意：太多糖让这类食物不健康。由语境可知需表否定含义，用health的形容词unhealthy。
3. 句意：会伤害他们的牙齿。tooth的复数形式为teeth，对应“他们的牙齿”（复数概念）。
4. 句意：做游泳、跑步这类运动是好选择。动名词短语作主语，谓语动词用单数is。
5. 句意：甚至一周一次能让你更强壮。much修饰形容词比较级，故用strong的比较级stronger。
6. 句意：Tom经常熬夜玩游戏，所以他起晚不吃早餐。前后为因果关系，用连词so。
7. 句意：他上课感到累。固定搭配in class表“在课堂上”，填介词in。
