B   Desert Greening — A Hope for the Future Desert greening is one of the most ambitious environmental projects in the world. The goal is to turn dry, barren deserts into productive green land. This is not just a dream. Scientists and experts have been working on this for many years. One of the biggest challenges is water. Deserts are dry because they receive very little rainfall. However, there are several ways to get water in deserts. Rainwater collecting can capture and store water for future use. Water saving techniques, like drip irrigation, can help use water more efficiently. Some experts are even exploring the use of seawater, as there are salt-loving plants that can survive in salty conditions. Planting trees is also very important. Trees help to hold the soil in place, prevent erosion, and create shade. They also provide habitats for animals and help to improve the local climate. Over time, areas that were once deserts can become thriving ecosystems. Desert greening is not easy, but it is worth the effort. It can help slow down climate change, reduce sandstorms, and create new opportunities for local communities. ( )6. What is the main goal of desert greening? A. To build new cities in deserts. B.

C   My Summer Experience at a Greening Project Last summer, I volunteered at a desert greening project in Inner Mongolia. I had heard about desertification in school, but I never really understood it until I saw it with my own eyes. The dry land stretched as far as I could see. It was both shocking and inspiring. Our team worked together to plant trees and build irrigation systems. Every morning, we carried young trees and tools into the sandy fields. It was hard work, but we were all motivated by the goal of making the land green again. I also learned a lot about the local plants and how they survive in such harsh conditions. One of the local experts taught us about the "Green Wall" project, which aims to stop the desert from spreading. At the end of the two weeks, I looked back at the area where we had worked. The small trees we planted were already starting to make a difference. It was a small step, but I felt proud to be part of such an important project. This experience changed my view on environmental protection. I realized that even small actions can help. I am now more committed to living a green life and encouraging others to do the same. ( )11.

D   A Letter About Environmental Protection Dear Emma, How are you doing? I hope everything is going well. I'm writing to tell you about a book I just finished reading. It's called "The Green Revolution" and it's about how small actions can make a big difference in protecting the environment. The book inspired me a lot. It gave many examples of how ordinary people have helped to protect the planet. One story was about a community that started a recycling program and reduced their waste by 50%. Another was about a school that planted a garden and grew their own vegetables. After reading the book, I decided to make some changes in my own life. I started a compost bin in my backyard, I use reusable bags when I shop, and I try to turn off lights when I leave a room. It may not seem like much, but I believe that every little bit helps.
