We've all heard this many times. But is it really true? Different people have different ideas. Team Breakfast (The "Yes" Side) Many doctors and health experts say breakfast is necessary. After sleeping for 8-10 hours, our body needs energy to start the day. Studies show that people who eat breakfast: • Have better attention in class or at work • Are less likely to feel tired before lunch • Usually have healthier eating habits overall A 10-year study of 5,000 people found that those who skipped breakfast had a 27% higher risk of heart disease. Team No Breakfast (The "It Depends" Side) Some scientists now say breakfast isn't for everyone. Dr. Michael Mosley, a health expert, explains: "If you're not hungry in the morning, forcing yourself to eat might not be good." Some research shows that skipping breakfast can help some people control their weight. However, most experts agree on one thing: WHAT you eat matters more than WHEN you eat. A breakfast of sugary cereal (含糖麦片) is worse than no breakfast at all. The School's View In Sunshine Middle School, the cafeteria now offers free breakfast to all students. Ms. Zhang, the school nurse, says: "We noticed many students coming to school hungry. They couldn't focus in morning classes. Now, over 300 students eat breakfast at school every day. Their grades are improving!" So, what should you do? Listen to your body. If you feel hungry in the morning, eat something healthy - eggs, fruit, or whole-grain bread. If you're not hungry, don't worry. Just make sure you eat well at other meals. 1. What does "Team Breakfast" believe? A. Skipping breakfast helps with weight control. B. Breakfast is important for energy and attention. C. People should only eat when they feel hungry. D. Sugary cereal is a good breakfast choice. 2. According to Dr. Mosley, what is his opinion? A. Everyone must eat breakfast. B. Breakfast is the most important meal. C. If you're not hungry, you don't have to eat. D. Skipping breakfast causes heart disease. 3. What change happened at Sunshine Middle School? A. They stopped serving breakfast. B. They started offering free breakfast. C. They asked students to eat at home. D. They found that breakfast doesn't help. 4. What do MOST experts agree on? A. Everyone should eat breakfast. B. Skipping breakfast is always bad. C. The quality of food matters most. D. Breakfast must include eggs. 5. Which of the following is a FACT, not an opinion? A. Breakfast is the most important meal. B. Sugary cereal is worse than no breakfast. C. Over 300 students eat breakfast at Sunshine Middle School. D. If you're not hungry, you shouldn't eat breakfast. 七、完形填空。（阅读下面短文，掌握其大意，然后从各题所给的四个选项中，选出一个最佳答案。） Mr. Wang is 75 years old, but he looks young and energetic.

A survey shows that 70% of students sleep less than 8 hours every night. The main reasons are too much homework, staying up late to use screens and early school start time. Lack of sleep (睡眠不足) is bad for teenagers. It makes them feel tired in class, affects their memory (记忆力) and concentration (注意力), and even leads to health problems like headaches and eye strain (眼疲劳). To help students get enough sleep, schools and families are working together. Schools have reduced homework to make sure students can finish it on time. Some schools have also put off the morning start time by 30 minutes. At home, parents ask their children to go to bed before 10:30 pm and don’t use screens before bedtime. Experts also suggest that students should develop a regular (规律的) sleep habit and do some light exercise before going to bed. 1. 信息填空（每空一词）： ① Most junior high students sleep less than ______ hours every night. ② The main reasons for lack of sleep are too much homework, staying up late to use screens and ______ school start time. 2. 选择最佳答案： Which of the following is NOT a way to help students get enough sleep?

B 解析： 本题考查观点提取。“Team Breakfast”部分列举了吃早餐的好处，包括提供能量、提高注意力等。因此他们相信早餐对能量和注意力很重要。A是“Team No Breakfast”的观点；C是最后建议部分；D与文中“sugary cereal is worse”矛盾。 考点： 区分不同观点 2. C 解析： 本题考查人物观点。第三段Dr. Mosley的话：“If you're not hungry in the morning, forcing yourself to eat might not be good.” 表明他的观点是如果不饿，不必强迫自己吃。A、B是Team Breakfast的观点；D是研究发现的关联，不是他的观点。 考点： 定位专家观点 3.

A 解析： 考查动词辨析。他也“记得 (remembers)”或“意识到”健康的生活不仅靠个人努力。根据上下文，A 最恰当。 5. C 解析： 考查形容词辨析。政府修建的是“健身 (fit)”公园。fit 此处作形容词，意为“健康的，适合锻炼的”。 6. A 解析： 考查动词辨析。社区中心“组织 (organizes)”一个健康俱乐部。 7. D 解析： 考查短语辨析。用智能手机“咨询 (ask for)”在线医生。ask for 请求，寻求。 8. A 解析： 考查动词辨析。政府和年轻人“支持 (support)”我们。 9. A 解析： 考查形容词辨析。得到支持让他们感到“安全 (safe)”和被爱。 10.

C 解析 1. 细节填空题：①定位第一段“A survey shows that 70% of students sleep less than 8 hours every night.”，直接提取数字8；②定位第一段“The main reasons are too much homework, staying up late to use screens and early school start time.”，直接提取形容词early。注意题干要求“每空一词”，确保数字和单词拼写正确。 2. 细节理解题（反向选择）：题干询问“下列哪项不是帮助学生获得充足睡眠的方法”，定位第三段：A选项“Reducing homework”（减少作业）、B选项“Putting off the morning start time”（推迟早上到校时间）、D选项“Developing a regular sleep habit”（养成规律睡眠习惯）均是原文提到的方法；C选项“Using screens before bedtime”（睡前使用屏幕），原文提到“don’t use screens before bedtime”（睡前不使用屏幕），该选项是错误做法，故选C。 $
