About 60% of our body is made up of water. Drinking enough water every day is important for staying healthy. First, water helps our body work properly. It carries nutrients to our cells, removes waste, and protects our joints (关节). When you don’t drink enough water, you may feel tired and get headaches. Second, water can help control weight. Sometimes people think they are hungry when they are actually thirsty. Drinking a glass of water before meals can make you feel fuller, so you may eat less. Third, water is good for your skin. It helps keep your skin soft and clear. If you want healthy-looking skin, drink plenty of water instead of sugary drinks. How much water should you drink? There is no one-size-fits-all answer. A common suggestion is eight 8-ounce glasses a day (about 2 liters). But if you exercise a lot or it’s a hot day, you may need more. A good rule is to drink when you feel thirsty and make sure your urine (尿液) is light yellow. Don’t wait until you feel very thirsty. Thirst is a sign that your body already needs water. Carry a water bottle with you so you can drink throughout the day. ( ) 1. What percentage of our body is made up of water?  A. About 50%.  B. About 60%.  C. About 70%.  D. About 80%. ( ) 2. According to the passage, what may happen if you don’t drink enough water?  A. You may feel hungry all the time.  B. You may feel tired and get headaches.  C. You may gain weight quickly.  D. You may have clearer skin. ( ) 3. How can water help control weight?  A. It makes you eat more.  B. It turns into fat in your body.  C. It makes you feel fuller before meals.  D. It increases your appetite. ( ) 4. What does the underlined word “suggestion” in Paragraph 5 probably mean?  A. Order.  B. Question.  C. Idea.  D. Problem. ( ) 5. What is the best title for this passage?  A. How to Choose Drinks  B. The Importance of a Balanced Diet  C. Why Drinking Water Is Good for You  D. How to Exercise Properly B阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 Screen Time and Teen Health Do you spend hours every day looking at a phone, tablet, or computer? You are not alone. Studies show that many teenagers spend more than 7 hours a day on screens. But too much screen time can be bad for your health in several ways. First, too much screen time is bad for your eyes. Staring at a screen for a long time can cause dry eyes, headaches, and blurred vision (视力模糊). Eye doctors suggest the “20-20-20 rule”: every 20 minutes, look at something 20 feet away for 20 seconds. Second, screen time can affect your sleep. The blue light from screens makes your brain think it’s still daytime. This makes it harder to fall asleep. Experts suggest stopping screen use at least one hour before bedtime. Third, too much screen time often means less physical activity. When you’re sitting and looking at a screen, you’re not running, jumping, or playing outside. Lack of exercise can lead to weight gain and other health problems. Fourth, too much screen time may affect your mood. Some studies find that teenagers who spend a lot of time on social media are more likely to feel anxious or sad. Does this mean you should stop using screens completely? Of course not. Screens are useful for school, communication, and entertainment. The key is to find a balance. Set limits for yourself, take breaks, and make sure you spend time on other activities like sports, reading, or talking with family face to face. ( ) 6. How many health problems caused by too much screen time are mentioned in the passage?  A. Three.  B. Four.  C. Five.  D. Six. ( ) 7. What is the “20-20-20 rule” suggested for?  A. To improve memory.  B. To protect eyes.  C. To help sleep better.  D. To control weight. ( ) 8. Why does screen time make it harder to fall asleep?  A. Because screens make noise.  B. Because screens are too bright.  C. Because blue light from screens tricks the brain.  D. Because people play games before sleep. ( ) 9. What does the underlined word “balance” in the last paragraph mean?  A. 平衡  B. 机会  C. 优势  D. 设备 ( ) 10. What is the writer’s attitude towards using screens?  A. Screens should be completely banned for teenagers. B. Screens are useless and harmful.  C. Screens are useful but need to be used wisely. D. Only social media is bad; other screens are fine. 三、阅读还原·七选五（共5小题；每小题2分，满分10分） 阅读下面短文，从短文后所给的七个选项中选出五个可以填入空白处的最佳选项，使短文意思通顺、前后连贯。选项中有两项为多余选项。 Turn Walking into a Habit Walking is simple and great for your body and mind.

Here are some important tips for developing healthy eating habits. First, eat a balanced breakfast every day. Breakfast gives you energy for the morning. Studies show that teenagers who eat breakfast do better in school than those who don’t. Second, eat more fruits and vegetables. They are full of vitamins and minerals that help your body grow strong. Try to eat at least five servings of fruits and vegetables each day. Third, drink plenty of water. Your body needs water to work properly. Avoid sugary drinks like soda and sweetened juice. They add extra calories but provide little nutrition. Fourth, don’t skip meals. Some teenagers skip meals because they think it will help them lose weight. However, skipping meals can make you feel tired and even lead to overeating later. Fifth, limit junk food. Foods like chips, candy, and fast food are high in fat, sugar, and salt. Eating too much junk food can lead to weight problems and other health issues. Finally, eat with your family when possible. Studies suggest that teenagers who eat family meals tend to have healthier diets and are less likely to develop eating disorders.
