Doing puzzles may help keep your mind sharp, but diet can make a big difference too. According to many studies, some foods and drinks may help to improve your memory. Why not try them? Scientists have found that sufficient (足够的) amounts of vitamin B2 can improve your memory. It’s found in common things like milk and dark green vegetables. You can add a banana to your breakfast. It will be easier for you to focus on what the teachers say. Studies have shown that eating fish once a week produces a 10 percent slower decline (衰退) in memory. Try a cup of tea. Not only does it keep your brain working right, it also helps to relax and fight against mental tiredness. We know that eggs are full of vitamin B12, which helps to fight against brain shrinkage (收缩) that is bad for the memory. To improve your intake of zinc (锌), you can eat more whole grains（谷物）. Whole grains help your brain work well. If you’re really serious about improving your memory, don’t forget to make time for a good breakfast. A study found breakfast helped people score better on memory tests. And when kids eat a morning meal, their exam scores improve. “You are what you eat.” A well-balanced diet is of course great for your body. What’s more, junk food like hamburgers, chips and candies is bad for your health and memory. You should try to keep away from it. 21．How many healthy foods and drinks are mentioned in the article? A．Six. B．Seven. C．Eight. D．Ten. 22．What can we learn from the last paragraph? A．A cup of tea can help you relax. B．Breakfast is also very important. C．Milk can help improve your memory. D．A balanced diet includes chips and candies. 23．What’s the purpose of this article? A．To tell students how to exercise their brains. B．To solve students’ problems of bad grades. C．To introduce students to some healthy diets. D．To encourage students to have morning meals. 24．The article may come from ________. A．morning news reports B．Chinese storybooks C．science fiction D．food magazines B篇 Do you know that your brain is like a muscle? The more you exercise it, the stronger it becomes. Here are some ways to improve your memory. First, get enough sleep. When you sleep, your brain organizes and stores what you have learned during the day. If you don’t sleep well, you may forget what you studied. Second, eat healthy food. Fish, nuts, and fruits are good for your brain. They help your brain work better. Third, exercise regularly. When you exercise, more blood flows to your brain. This helps you think more clearly and remember things better. Fourth, try to learn something new. Learning a new language or a musical instrument can help create new connections in your brain. This makes your memory stronger. Finally, stay relaxed. When you are stressed, your brain cannot work well. Take deep breaths or listen to music to relax. 25．What is the main idea of the passage? A．How to get better grades in school. B．How to improve your memory. C．Why sleep is important for health. D．How to exercise your body. 26．According to the passage, what happens to your brain during sleep? A．It stops working. B．It organizes and stores what you have learned. C．It forgets everything. D．It becomes more active than during the day. 27．Which of the following is NOT mentioned as a way to improve memory?

B．To give advice on improving memory. C．To introduce a new book on the brain. D．To explain how the brain works. IV. 任务型阅读（共10分） Have you ever wondered why a good night’s sleep helps you do better on a test? Scientists have discovered that while you are sleeping, your brain is still very active. It replays (重放) the day’s experiences without any interference (干扰) from new information. This replay process improves the connections among different parts of the brain, making memories clearer. In other words, during sleep, your brain is not resting—it is working hard to organize and store what you have learned. At the same time, it also prepares itself to receive new information the next day. This double task makes sleep necessary for learning. Without enough sleep, your brain cannot perform these important tasks. That is why you may feel upset and forgetful after a poor night’s rest. This finding changes our understanding of how memory works. To improve your memory, you don’t just need to review your notes. You also need to give your brain enough quiet time to process everything. So next time you stay up late studying, remember: A few more hours of sleep might be more helpful than a few more pages of reading. Try getting eight hours of sleep every night for a week, and you will notice a clear difference in your ability to remember things. Sleep is not wasted time—it is brain training time. Your brain thanks you for it. So, turn off your phone and go to bed early tonight. 30．What happens to your brain while you are sleeping? 31．Why is sleep necessary for learning? 32．How can you improve your memory according to the passage? 33．According to the writer, which is more helpful when you stay up late, a few more pages of reading or a few more hours of sleep? 34．How many hours of sleep does the writer suggest getting every night?
