(3m)Write a short passage about what we can do to protect our earth, according to the suggestions above.EXERCISE A sandstorm refers to a high amount of wind occurring in sandy areas, usually in deserts, where the wind speed is able to lift the top layer (层) of sand from the ground, and push it in every direction. The sand involved in the sandstorm can reach heights of about 3.05m15.24m. It is very dangerous to experience a sandstorm. Sand can get into the nose, eyes, mouth and lungs. If you happen to be caught in sandstorm, you must protect yourself by wearing masks, scarves(围巾) and so on. If youre driving when such a storm approaches, its advised that you pull off the road, since its difficult to continue driving. This is also important since vehicles can fail in during sandstorms and you could end up stuck on the road. Most sandstorms occour in spring, and during the daytime. Many of the areas around the Persian Gulf and the Sahara Desert are associated with the most serious storms. Since its a natural phenomenon(现象), it cant be entirely controlled. In areas that are natural desert regions, you cant always prevent a sandstorm. Theres much evidence that the planet Mars(火星) has dust storms, and clearly, no human intervention(介入)is responsible for such. Though it can move whole sand dunes and destroy crops, a sandstorm is not without benefit(益处).1.
