Time to Stay Healthy
Being overweight(超重的) isn’t good for our health. Our country has made a plan to help everyone stay healthy.
Are you overweight? Your Body Mass Index(BMI)(体质指数) helps you know!
BMI=$\frac{\mathrm{weight(kg)}}{\mathrm{height}^2(\mathrm{m}^2)}$ =
注:凡BMI大于或等于相应性别、年龄组“超重”界值点者为超重。

| 10 | 19.2 | 19.5 |
| 11 | 19.9 | 20.5 |
| 12 | 20.7 | 21.5 |
To help us eat healthily and happily, our country gives some suggestions.

• Eat healthy snacks like nuts and yogurt. Don’t eat any snacks after 9 p.m.

解析
【分析】
先通读全文，明确文章围绕健康饮食与BMI体质指数展开的内容。解题时，第1题需定位12岁女孩的BMI超重界值，对比Alice的BMI判断；第2题先计算Ken的BMI，再与10岁男孩的超重界值比较；第3题直接提取每周食物种类的要求；第4题逐一核对选项与原文细节；第5、6题结合健康建议给出合理回答。
【解析】
1. 由BMI对照表可知，12岁女孩的超重界值为21.5，Alice的BMI是23，23≥21.5，属于超重，故选A。
2. 先计算Ken的BMI：身高140cm=1.4m，BMI=体重(kg)/身高²(m²)=35/(1.4²)=35/1.96≈17.86；10岁男孩的超重界值为19.2，17.86＜19.2，所以他不超重，故选B。
3. 原文提到“Try to eat 12 or more different food every day and 25 or more every week.”，即每周应吃25种以上，故选B。
4. 选项A：原文说“it is good to have 20 minutes for breakfast and 30 minutes for lunch and dinner”，午餐需30分钟，A错误；选项B：原文“Don’t eat any snacks after 9 p.m.”，说明9点后吃零食不健康，B正确；选项C：原文“You can eat ice cream or cookies, but only once or twice a week.”，并非不能吃，C错误，故选B。
5. 结合健康饮食建议，可回答健康食物，如I’m going to eat vegetables, fish and rice.（合理即可）
6. 根据健康建议，可回答No, I don’t.（符合要求）
【答案】
1.A 2.B 3.B 4.B
5. I’m going to eat carrots, tomatoes and fish.
6. No, I don’t.
