Dear David,
I’m glad that you’ve noticed our efforts directed towards environmental protection. Thanks you for your concern.
As too much use of plastic bags have caused serious white pollution, our government encourages us to use environment-friendly shopping bags. These bags are made of a variety materials that can be easily treated when they become rubbish. Besides, it can be reused. More and more people in China have realized the advantages of such bags but started using them.
I believe that the widely use of these shopping bags can greatly improve our environment. This is one of the many more steps we are taking to make our country an even clean place.
Yours,
Li Hua

Do you read reviews after you see a movie? I use to do that, but I usually regretted. I read so much about a movie on advance that I often ended up not go to see it at all. The writers point out everything that is wrong with the film, but seldom mentions anything good about one. They also tell many things and even the ending of the movie. Lately I have changed way I choose movies to watch. I read reviews afterwards if necessary. What is very importance to me is that I don’t watch the talk shows in that people discuss movies. And I don’t ask other people how they like of it. Now, I enjoy myself even more.

Recently, our school has held the meaningful discussion on whether it is reasonable for middle school students to have classes on weekends. Some of our classmates believe we should have classes on weekends because we can make fully use of free time to review the lessons we had learnt. Some others are against the opinion, saying we had better to have a good rest on weekends so that we can work effective during the weekdays. The rest agree with neither of the opinion. They have the view which keeping the balance between work and play are important for us. They suggest one day of the weekend should used to learn our lessons and during the other day we do something interested or have a rest.

I like riding my bike. Though it is not very new, but it is my best friend. I find very convenient to go anywhere with a bike. Riding gives me not only exercises but also pleasure. I use my bike almost in summer when the weather is warm and dry. It can be very pleasant in winter when it is cold and rain is pour down. It can also be very dangerous. Therefore, I am very carefully on my bike. In fact, accidents are not the only problem. Once I went to bookstore on my mother’s bike to buy some books and come out to find the bike missed. Now I have two strong locks.
