        As we can see，the sandstorm is getting worse and worse，by which，our life and health have been affected greatly in many ways，like suffering from breathing illnesses.The earth is our home and we have the duty to take care of it，not only for ourselves but also for our future generations.
     Fortunately，more and more people have become aware of this problem.Many effective measures have been taken to deal with it by the government.I think we should follow the following advice.First，go to activity on tree-planting as often as possible.Besides，raise our awareness of environment protection.
