They provide homes for thousands of species of animals and plants. They also help control the climate by absorbing carbon dioxide and producing oxygen. However, many forests around the world are being cut down for wood, farmland and urban development. This not only destroys the homes of animals but also breaks the ecological balance. For example, when forests are cut down, the soil becomes loose and easily washed away by rain. This leads to floods and landslides. Also, without trees, the air becomes less fresh and the temperature rises. To protect the balance of nature, many countries have taken actions. Some have set up national parks and nature reserves where cutting trees is not allowed. Others have started reforestation projects, planting millions of trees every year. These efforts help to restore the balance and protect the environment for future generations. 26.What do forests provide for animals and plants? A. Food. B. Homes. C. Water. D. Sunlight. 27.What happens when forests are cut down? A. The soil becomes rich. B. The air becomes fresher. C. The temperature rises. D. There are fewer floods. 28.What does the word "reforestation" mean in the passage? A. Cutting down trees. B. Protecting trees. C. Planting new trees. D. Using wood from trees. 29.Why do countries set up national parks? A. To develop urban areas. B. To farm the land. C. To protect the ecological balance. D. To produce more wood. 30.What is the main idea of the passage? A. The importance of forests to nature's balance. B. The reasons why forests are cut down. C. The ways to use wood from forests. D. The effect of climate change on forests. (二)阅读短文,判断正(T)误(F) How to Keep a Balance Between Work and Life Nowadays, many people find it hard to balance work and life. Here are some tips to help you. First, set clear boundaries. Don't check work emails or take calls after work hours. This helps you separate work from your personal life. Second, make time for hobbies. Doing something you love, like reading or painting, can help you relax and reduce stress. Third, exercise regularly. Physical activity not only keeps you healthy but also improves your mood. It's also important to spend time with family and friends. They can give you support and make you feel happy. Finally, learn to say "no". If you have too much work, don't take on more tasks. This will prevent you from being overworked. Remember, a balanced life is not about doing everything perfectly. It's about making time for the things that are important to you. 31.Many people don't have trouble balancing work and life now. 32.Checking work emails after work hours is not a good idea. 33.Hobbies can help people relax and reduce stress. 34.Exercise has no effect on people's mood. 35.It's good to take on as many tasks as possible even if you're busy. (三) A balanced diet is essential for good health. It means eating a variety of foods from different food groups to get all the nutrients your body needs. Food groups include fruits, vegetables, grains, protein foods and dairy products. Each group provides different nutrients. For example, fruits and vegetables are rich in vitamins and fiber. Grains give you energy. Protein foods like meat, fish and beans help build your muscles. Dairy products provide calcium for strong bones. Eating too much of one food group and not enough of others can cause health problems. For example, eating too much junk food can lead to weight gain and heart disease. Not eating enough vegetables can make you lack vitamins. To have a balanced diet, you should eat meals regularly and avoid skipping breakfast. You should also try to eat more fresh foods and less processed foods. Remember, small changes can make a big difference to your health. 36.What is a balanced diet? A. Eating only one type of food. B.

I stopped playing the piano, which I loved, and didn't hang out with my friends much. But soon, I felt unhappy. I didn't enjoy studying anymore and my grades even started to drop. My mother noticed this and talked to me. She said, "You need to balance study and your hobbies. Doing things you love will help you relax and study better." I took her advice. I started playing the piano for an hour every day. I also met my friends for a walk every weekend. Slowly, I felt happier and my grades improved. I realized that balance is important.
