Choose the best answer(根据短文内容，选择最恰当的答案) Water is one of the most important natural resources on Earth. Every living thing needs water to survive. However, many people around the world are facing serious water shortages. In some countries, people have to walk for hours just to find a small amount of clean water. One major reason for water shortages is the rapid growth of the world's population. As more people are born, more water is needed for drinking, farming, and industry. Pollution also plays a big role. Factories sometimes dump waste into rivers and lakes, making the water unsafe to drink. Climate change is another cause. In some areas, it brings longer dry seasons and less rainfall. There are many ways we can help save water. First, we should turn off the tap while brushing our teeth. A running tap wastes about six litres of water every minute! Second, fixing leaking pipes can save a lot of water at home. Third, governments can help by building systems that recycle water for farming and other uses. Water conservation is everyone's responsibility. If we all work together, we can make sure that future generations have enough clean water to live healthy lives. ( )1.

Choose the best answer and complete the passage(选择最恰当的选项完成短文) In recent years, more and more people have started to realise the importance of protecting the environment. Many people think that it is essential to reduce waste and save resources. However, there are still some people who 1 the problem and believe that it is not their responsibility to help. These people often ignore the fact that every small action we take can make a difference. For example, instead of throwing away plastic bottles, we can recycle them to 2 the amount of waste in landfills. Moreover, the government has taken many steps to encourage people to protect the environment. In some countries, there are laws that make it mandatory(法定的) for people to sort their rubbish. 3 , many people still do not follow these rules, and it seems that the laws alone cannot solve the problem. It is important for everyone to understand that the government's efforts are not enough without the support of the public. One of the most effective ways to protect the environment is to reduce energy consumption. People should turn off lights when they leave a room, take 4 showers, and avoid using unnecessary plastic bags. These small changes may seem insignificant, but if everyone makes an effort, the impact can be 5 . 6 , educating the younger generation about environmental protection is equally important. Schools should teach children about the importance of caring for the planet and encourage them to take action. By raising 7 from an early age, we can ensure that future generations will take better care of the environment. It is clear that protecting the environment requires the effort of every person. We must work together to create a cleaner, greener world for the future. ( )1. A. ignore B. accept C. solve D. understand ( )2. A. decrease B. increase C. delay D. recycle ( )3. A. Therefore B.

Read the passage and complete the tasks(根据短文内容完成任务) Every Friday afternoon,13-year-old Lily volunteered at the town's old library. The building was ancient, with tall wooden shelves and the scent of aged paper lingering in the air. Most visitors came during the day, but Lily preferred the quiet hours before closing. One evening, as she was organizing books in the history section, she heard a faint whisper. She turned around, but no one was there. Assuming it was her imagination, she continued working. However, the whispers grew louder, forming words: “Seek the hidden truth.” Curious and a bit frightened, Lily followed the sound to a shelf filled with old, dusty books. One book, bound in dark leather without a title, seemed to emit a soft glow. She opened it and found handwritten notes between the printed lines, detailing a secret room beneath the library. Determined to uncover the mystery, Lily searched the library's floor and discovered a loose tile(瓷砖). Beneath it was a small key. Using clues from the book, she found a hidden door behind a bookshelf. The key fit perfectly. Inside, she found a room filled with ancient manuscripts and artifacts.
