Human brain is the most complex and intelligent mechanism in the world. It is the major factor that distinguishes man from animals. With our brain we get to know the world and make a good use of the world to our benefit.
Our brain is a product of constant use through millions of years. Other things can be used up, but used properly, our brain can never be exhausted. In fact, the more we use it, the more capable and efficient it will become. Excessive use of the brain, however, will causea lot of problems. So it is useful to know how to use our brain wisely.
First, handwork or physical labor is good exercise as well as rest for our brain. Doing handwork and brain work alternatively can help develop both our brain and hands. Secondly, we should avoid doing brainwork for long hours on end. The brain, though 3% of the body weight, when at work, consumes 20% of the oxygen carried by 16% of the blood in circulation. A long period of brainwork may cause, through lack of bodily activity, slow blood circulation and inadequate oxygen supply to the brain, resulting in inefficiency and possible damage to the brain.

My View on Fake Commodities
Fake commodities can be found, now and then, in the market, which has aroused a lot of public attention. It is reported that these commodities range from foodstuff, clothes to radios, and TV sets and even medicines.
Fake commodities are harmful in many ways. To begin with, they bring about great loss in both properties and lives. For instance, if someone buys some fake medicines, it may not cure him of his illness, on the contrary, it may probably make his illness worse or even put an end to his life. Besides, fake commodities may impair the profit of the manufactures who produce the real products by making the consumers suspicious of these products, thus causing social problems.
There are many ways to get rid of fake commodities. First, laws should be enforced to punish those who produce these products. Second, people should be advised how to tell the genuine commodities from the fake ones. Moreover, people should not buy things just because they are cheap and attractively advertised. Furthermore, they should be encouraged to report to the relevant authorities in case they have bought a fake commodity. In a word, if the whole society work together to solve this problem, I think fake commodities will have nowhere to exist

A Letter to the University President about the Canteen Service on Campus
January 12th, 2002
Dear Mr. President,
I'm a student in our university. I am writing this letter to inform you of the canteen service on our campus.
Generally speaking, we are not content with the canteen service in our university. The reasons are as follows:
First, although quality of the dishes is not bad, yet, most of the dishes remain unchanged all the year round. More and more students are complaining about eating the same food every day. So I think variety of the food is the most urgent problem that should be solved.
Second, the environment is not the same as we desire. Many students always talk so loudly that we can't enjoy our meals. So I suggest that there be some slogans on the wall to remind them to be quiet, and some soft background music to help us relax.
By the way the canteen workers are very patient in providing us with the service. So I think they should be given more incentive to offer us better service in the future.
The above mentioned are not just what I think, but the idea of many of my classmates'. We will be very glad if you can take our suggestions into consideration.
Best wishes,
Yours Sincerely
Li Ming
