一、(2025·盐城阜宁县期末改编)
亮亮常听到大人念叨“减肥”，那么，体重是越轻越好吗？在什么情况下我们才需要“减肥”呢？阅读所给材料，判断正(T)误(F)。
主题：人与自我——生活与学习
话题：健康体重
体裁：说明文
难度：★★★
新素养 健康生活 Today，many children are overweight(超重的). In China，one in ten children has this problem. How can we judge(判断)if(是否)we are overweight？BMI(体质指数)can help us know if we are healthy. We can know our BMI clearly according to the table below.
Beibei is a student in Grade 5. His height is 1.5 metres. His weight is 60 kilograms. So，his BMI is about 26.7 according to the formula. He has to lose weight now.
A healthy body is very important to everyone. There are many ways to help us keep fit. In the morning，we can get up early，go outdoors and do morning exercises.

)5. To keep fit，we should not only do more exercise，but also be in a good mood(心情).答案：1. F
2. T 解析·根据“There are many ways to help us keep fit. In the morning, we can get up early ... Running and swimming can also help us be healthy.”可知，为了保持健康，我们可以早起、跑步和游泳。故填 T。
3. F 解析·根据“Today, many children are overweight. In China, one in ten children has this problem.”可知，在中国每十个孩子中就有一个超重，而不是三个。故填 F。
4. F 解析·根据表格中的计算公式可知，Amy 的 BMI 约为 15.6，对照表格的第三行可知，Amy 太瘦了。故填 F。
5. T

【分析】
这是一道结合说明文阅读与数据计算的判断正误题，解题思路如下：
1. 先通读文章和表格，明确BMI计算公式和不同BMI对应的健康状况，以及文中提到的健康生活方式等关键信息；
2. 针对每一道小题，回到原文或表格中寻找对应依据：
第1题：找到Beibei的BMI数值，对照表格判断其健康状况，对比题目表述；
第2题：定位文中关于保持健康的方法的语句，判断题目表述是否符合；
第3题：找到文中关于中国超重儿童比例的内容，对比题目数字；
第4题：运用BMI计算公式算出Amy的BMI，对照表格判断其健康状况，再对比题目表述；
第5题：结合文中提到的锻炼和保持心情愉快的内容，判断题目表述是否正确。
【解析】
1. 第1题：根据文中“his BMI is about 26.7 according to the formula. He has to lose weight now.”，对照表格可知，24≤BMI＜28属于“overweight（超重）”，并非“too thin（太瘦）”，所以该表述错误，填F。
2. 第2题：根据文中“There are many ways to help us keep fit. In the morning，we can get up early，go outdoors and do morning exercises. Running and swimming can also help us be healthy.”可知，早起、跑步和游泳都是保持健康的有效方法，表述与原文一致，填T。
3. 第3题：根据文中“In China，one in ten children has this problem.”可知，中国每十个孩子中有一个超重，而题目中“Three in ten（每十个中有三个）”的表述与原文不符，填F。
4. 第4题：根据BMI计算公式：$\mathrm{BMI}=\mathrm{weight}÷(\mathrm{height}×\mathrm{height})$，代入Amy的身高1.5米、体重35千克，可得$\mathrm{BMI}=35÷(1.5×1.5)\approx15.6$，对照表格，$\mathrm{BMI}＜18.5$属于“too thin（太瘦）”，并非“good（健康）”，所以该表述错误，填F。
5. 第5题：根据文中“There are many ways to help us keep fit... Running and swimming can also help us be healthy. We should try to make ourselves happy too.”可知，保持健康不仅需要进行锻炼，还要保持良好的心情，表述与原文一致，填T。
【答案】
1. F
2. T
3. F
4. F
