   Human health has always been dependent on our relationship with our environment. Humans, like other animals, are constantly transformed by natural forces in the environment that act on them, and they in turn continuously transform their environment. Humans are part of a dynamic system in which they continuously interchange matter and energy with the world about them. It must never be ignored that in the final analysis, concern for the public's health is the paramount reason for environmental action. On the other hand, public health workers themselves must be careful to avoid instituting or perpetuating actions or programs that are too narrow, environmentally ill-advised，or outdated.
   Our environment in reality is a multifaceted system that encompasses the physical and biotic realms and the cultural setting fashioned by our unusual cerebral capabilities. The interrelations between the total person and the total environment are dynamic. Each makes aggressions on the other. Each in turn responds to these aggressions. To support our biologic, cultural, and uniquely technologic needs, we boldly and continuously alter the naturally occurring environment and create ever new environments. Often this is done with inconsistency and without thought of the total or ultimate consequences.

   With the rapid growth of the Chinese economy, investment is becoming an increasingly important economic channel to promote economic growth. But for ordinary people to decide their investment in a stock market, several elements must be considered.
   The most important factor is profit. People always want a maximum investment benefit. The primary principle of stock market is buying at bottom and selling at a high point. Actually, a high point does not always mean a climax of a year. And if people abide by this principle and keep a higher velocity of money transfer, they can gain more margins. But some people prefer a long-term investment. They buy stock at a low point, and then just hold it and wait for a long period. In fact, these people are capital investors rather than money operators, because they only favor the companies in which they have invested. But they should know, benefit and risk may increase simultaneously with the fluctuations in a stock market. Therefore, it is better to sell stock at an expected point and put money in their pockets with which to wait and choose a new low point.
   Secondly, people should invest money into different stock markets based on their income, which decides not only the selections of investment, but also the amount of investment. Generally speaking, the money that ordinary people have for investment is limited, because most of it is from their salary earned on the job. It will certainly restrict these investors to allocate their money in well-diversified companies. No matter how much money can be afforded, however, diversity is a golden principle for investors to transfer the risks.
   The living consumption, the psychology in investment, the investment environment such as national economy, political and military policies, are all included in the elements of stock investment.
   To be good at stock investment, one has to learn all relevant knowledge.

   After joining WTO, international communication and cooperation are becoming increasingly close. It is obvious to all that China has made great achievements in almost every aspect. However, one issue appeared in many fields, especially in foreign trades, that is language obstacle. At the very beginning, it is language barriers that block the development of foreign trades and even sometimes cause great losses. Therefore, there are more and more schools that attach importance to education of foreign languages, especially in English teaching.
   We must admit a fact that there is a large population in China and people's education degree is various. People who can understand or speak English are quite small. It is no doubt that English language teaching is far from enough and we should pay much attention to it. Here is an example. Most of college students who are not majored in English, until their graduation from college, it is tough for them to make a very simple sentence, let alone speaking fluent English. When they come across a foreigner, they can only say "hello". One main reason that leaded to this result is the problem of our educational system. When teachers give an English class, they're accustomed to apply more Chinese rather than English. As for students, they seldom have English environment to practice it and the chances of speaking English is too rare. So it is still a long way to polish up this situation that cause the English level of students is very low. Along with many graduates who studied abroad now returned to became college English teachers, such situation is gradually improving. Under their efforts, great progresses can be seen in English language teaching. Yet if we'd like to cultivate sufficient students who can utilize English fluently, there are still many difficulties needing us to overcome.
   From statements above, we can draw a conclusion that English language teaching in Chinese education is not overemphasized. Contrary to that, we should strengthen it more than ever.

   Here comes an issue that whether China is ready for e-education, which is conduct in the environment of the internet. Some people or researchers believe that since the reform and opening-up of China in 1978, the economical environment and the quality of human resources has improved a lot, and when enter into the 21st century, which also been known as the information era, the quality of our educator and the economic capability of our country have been getting more and more better, so it is just the time to develop the e-education.
   For one thing, we can not defy that the development of our economy has become better than the beginning of the reform and opening-up period of China. But the development of our economy is very unbalance, which means that there exist great regional disparities in economic prosperity and its durable capabilities. There is no problem of bearing this sum of expenses in the east of China where the economic situation is good. But the situation in the interior of China is just contrary, serious questions such as lack of fund and low quality of the human would lead to the failure of this educational pattern.
   For another thing, the internet environment and the internet regulation system is defective. Along with the flourish of the information technology, computer games, violence contents and network crimes all companied with it. E-education, which may basically established on internet, would face a problem of leading to no progress to the being educated if there is no effective regulation on the network behavior or healthy tied mechanism.
   In conclusion, China is not ready for e-education at present. This pattern of education could be realized until the establishment of healthy internet tied mechanism and the development of Midwest Economy.
