As a result, the environment will become greener and our lives will be better. Let's work together! 11. Read and learn the great examples. Dear classmates, Our hometown suffers from serious sandstorms. The land is so sandy that the soil is easy to blow away. It is hard to grow corn or vegetables. To solve this, the government should plant more bushes and trees. More green plants can stop the wind. Also, we can build more bridges across rivers and make the roads wider, just like those in our capital Beijing. With these actions, we will get more farm products and a better environment. The result will be a green and beautiful hometown. Let's do it now!
