Ⅱ. 沙漠变绿洲 塔克拉玛干沙漠，中国最大的沙漠，在中国人民的不懈努力下，环境越来越好。让我们一起见证沙漠变绿洲的奇迹吧！（每空一词）
The Taklimakan Desert，one of the largest deserts in the world，used to be a huge area full of sand. In the past，it was a vast sea of sand but almost no life lived there. The sand dunes(沙丘) were high，and the weather was extremely hot and dry. It seemed like a place where nothing could grow.
But things have changed greatly. Chinese scientists and workers decided to fight against the desert. They have been working hard to turn this desert green. They came up with many good ideas. First，they planted special plants. These plants have strong roots that can hold the sand and their leaves can stop the sand from moving.
To help the plants grow，people also built a smart water-giving system which is called "drip irrigation". It works like a tiny water drop falling onto the roots of plants slowly. This way，the plants get enough water without wasting it. The water-saving method is very important because water is so precious(宝贵的) in the desert.
Year after year，their hard work paid off. Now，large parts of the Taklimakan Desert are covered with green plants. There are rows of trees and areas of grass and even some small lakes have appeared. The green plants not only make the desert look beautiful but also stop the sandstorms. Some animals that left the desert before are coming back because they can find food and water here again.
The change is not only good for the environment but also for the people living around the desert. Local people can grow some fruits and vegetables in the green areas. Some have even started new businesses. For example，they offer camel rides in the green areas to tourists and show tourists around the "green desert". They also sell local handicrafts to the visitors. These bring more money to their families and make their lives better.
The story of the Taklimakan Desert shows that with hard work and good ideas，we can make a big difference to the environment.
