Directions：
Restrictions on the use of plastic bags have not been so successful in some regions. White pollution is still going on. Write a letter to the editor（s） of your local newspaper to
give your opinions briefly and
make two or three suggestions
You should write about 100 words. Do not sign your own name at the end of the letter. Use Li Ming instead. You do not need to write the address.

Dear Editor：
I am writing this letter to draw your attention to the deteriorating situation of white pollution in some regions despite the implementation of restrictions on the use of plastic bags.
In order to put an effective stop to the wide spread of white pollution， I would like to make the following suggestions . Firstly， the price of plastic bags should be further raised； Secondly ， special government departments should be established to supervise the making and using of plastic bags to ensure they are used when really needed.
I hope my suggestions would be of help and thank you for your attention.
