I choose to write about ___________ (water pollution/air pollution…)
because __________________________________________________. Protecting Our Hometown My hometown used to be a beautiful place. Thick forests and green grass could be seen everywhere. However, nowadays, Sandstorms often strike my hometown, from which people suffer a lot. In the last few years, people in my hometown have cut down too many trees in order to build houses. What’s worse, the farmers dig up grass to plant more crops. As a result, land gradually becomes desert. What they have done makes the sandstorms more and more serious. In order to prevent the process of desertification, I suggest that people should plant more trees instead of cutting them down. Meanwhile, the government should call on people to take good care of the forests. If so, our living conditions will soon be improved.OutlineRead the passage. Find the main idea for each paragraph.
