Recently, the incident of Sanlu milk powder has become the focus of people’s attention. According to the investigation of related departments, the powder was found to contain a chemical called C3N6H6 which can cause great damage to infants’ health. So far, four children have died and approximately 54,000 have developed illness after drinking the milk.
From this incident, we can see that there are still more things to be done. Firstly, the government needs everything possible to ensure the quality of products, particularly the safety of food as this concerns everyone's life. Secondly, as for the producers, it is very important for them to be morally honest. They should never try to pursue profit or economic growth at the expense of health and life of people. Thirdly, we consumers must attach importance to the things we eat and develop an awareness of how to protect our legal rights if cheated. Only in this way will we be able to build a more secure and harmonious society.
Do We Need Space Exploration？
Man has been fascinated by outer space for thousands of years. It has been almost over forty years since man's first landing on the moon. Now， some people believe that space exploration is a sheer waste of time and money. They point out the fact that it cost billions of dollars to carry on the space research， but a little information was brought back.
However，every coin has two sides. There are still a majority of other people who believe that space exploration has more advantages. And I agree with those people. Many new products， such as weather and communication satellites， are also products of space programs， and they have benefited people all over the world. And what's more， scientific knowledge about outer space has been acquired by mankind.
We believed that it wiil bring more benefits in the future， which we can not even imagine now. Space exploration is a challenge to human beings. That's why several nations try hard to carry out space exploration continuously.
Chinese astronaut to spacewalk on Sep. 27
An astronaut will spacewalk outside the capsule on the afternoon of September 27, Gu Yidong, the commander-in-chief and chief designer of the spacecraft application system of China's manned space program, explained to the media on September 23.
Earlier on September 23, several news portal websites reported that a Shenzhou VII astronaut would spacewalk at 16:30 – the day after launch. They said if Shenzhou VII was launched at 21:10 on September 25, the astronaut would leave the capsule at 16:30 on September 26.
However, Gu corrected the reports, explaining that the spacewalk would begin on the day after orbit is achieved. If the launch was on September 25, the spacecraft would enter orbit on 26, and the astronaut would spacewalk on the afternoon of 27.
Experts said the spacecraft would climb to an altitude of 300 km and then into outer space. Though the astronaut would be protected by the special seat and garment, he would need a certain period of time to adjust to the environment. He might experience nausea, vomiting or other discomfort if he left the capsule too early.
Six astronauts – the three confirmed Shenzhou VII team members Zhai Zhigang, Liu Boming, and Jing Haipeng, plus their back-ups – moved to the Jiuquan Satellite Launch Center in northwestern China's Gansu Province on September 21.
One of the three astronauts onboard Shenzhou VII will step out of the capsule and conduct a historic space walk that will be telecast live.

How to Solve the Housing Problem in Big Cities
Housing problem has become one of the biggest concerns for people in big cities. With the rapid development of industry and great increase in employment, more people are swarming into cities. Accommodations have become ever difficult, causing inconvenience to people＇s work and life.
Many proposals have been put forward to solve this problem. Some suggest that more high buildings be constructed. Some insist that the underground be developed. Others propose that satellite cities be built. Still others argue that cities should be expanded to move people to the suburbs.
Personally, I am in favor of building satellite cities in the suburbs. For one thing, these cities are not far away from big cities. It is still very convenient for people to go downtown as they wish. For another, the fresh air and adequate space there will be a great attraction for people who are living in crowded cities. If many people move to the satellite cities, the housing problem in big cities will cease to exist. I am against the idea of developing the underground. Because compared with building satellite cities, it is more costly. With each house to light even at daytime, we need a lot of electricity. Besides, it witt deprive people of the fresh air and bright sunshine which they can get so easily when they are above the ground.
The Importance of Physical Exercises
It is reported that the health of young people in China, college students in particular, is not as good as is supposed to be. There are many reasons for this fact, but the main reason is that many people ignore the importance of physical exercises.
Why, then, are physical exercises so important to our health? First, physical exercises can improve blood circulation, speeding up the supply of nutrients and oxygen to every part of the body and the removal of waste from the blood through sweating and exhalation. Secondly, physical exercises can promote a healthy metabolism. It helps with the digestion and absorption of food, thus giving everyone a good appetite. Thirdly, physical exercise can help consume excessive fat in the body, preventing people from putting on too much weight, thus keeping them in good shape. Finally, after physical exercises we usually need a good rest and a sound sleep at night, refreshing us for the next day＇s work.
In conclusion, physical exercises not on[y keep us fit and strong, but also help us to be successful in our lives. It is, therefore, strongly suggested that young people spare some time to take an active part in various kinds of physical exercises.
My Idea on Teacher student Relationship
Teacher student relationship plays an important role in school life. A good relationship will make learning interesting and teaching enjoyable. A bad relationship, however, can make learning dull and teaching unpleasant.
To have a good teacher student relationship, it is important that the teacher and the student understand each other and respect each other. The teacher must know that he should be neither too tough, nor too permissive. If he is too tough, the student may be frightened and discouraged. If he is too permissive, the student may become lazy and careless. So his attitude should be between the two extremes. He should be strict yet friendly. As for a student, he should know that what the teacher does is for the benefit of his students. He should always show his proper respect to the teacher. Moreover, he should always be eager to learn and willing to work hard. If he is modest, he will learn more than just knowledge from his teacher.
In one word, a good teacher student relationship can be mutually beneficial. The student may find the learning process both fruitful and enjoyable while the teacher may find his teaching satisfactory and pleasant.
With the development of economics as well as the improving life standard, more and more people possess private cars.
As each coin has two sides, there are also disadvantages in such a trend. First of all, the air and noise pollution is undoubtedly going from bad to worse. The poisonous gas the private cars send out is not only of great harm to the environment around us, but to our human bodies as well, especially to the respiratory systems. Private cars, of their owners most are new drivers, meanwhile, are consequently easy to result in traffic jams or even accidents. You can imagine how worrying the situation can be when you are in a hurry!
Such being the case, some immediate measures must be taken to prevent it in my opinion. For instance, we should pay more attention to the environmental protection to refresh the air, if possible, to reduce the noise level. It is expected that more advanced technology can make it a reality to replace the poisonous gas with one which both saves energy and causes no harm, thus making our daily life more satisfying!
