【答案解析】Dear editors: I am writing the letter in purpose of drawing your attention to the fact that some people still use plastic bags in spite of restrictions on the use of them, and I will try to make some conducive recommendations concerning the white pollution. To begin with, our government should continue to exercise strict control over the production and abuse of plastic bags, punishing those who fail to obey relevant laws and regulations. What’s more, people should be educated from childhood to cultivate the awareness that we have only one planet and our natural resources are exhaustible. Last but not least, there should be some substitutes for plastic bags, such as bags made of paper or cloth which can be reused and degraded. I hope you will find these proposals useful, and I would be ready to discuss this matter with you to further details. Your prompt attention to my recommendations will be highly appreciated. Yours sincerely, Li Ming
