　　11. Choosing an Occupation

　　Every one faces the problem of choosing an occupation after graduation from college or university, which plays a vital role in his life. An appropriate occupation makes a man work with zest and vigor, as well as contribute to his country. To make a wise choice, two important things should be taken into consideration. One is the interest, the other, the demands of people and society. Only if the two aspects are connected, can a man show his talent and ability to the best advantage. If the two conflict, the former should be under the latter, for the peoples interests are more important than the individuals. In regard to my choice in the future, I am fond of learning foreign languages; what is more, with the implementation of the Open-Door Policy, exchange between home and abroad in economy and culture has been growing significantly, thus Im determined to be a qualified interpreter.

　　12. The Brain and the Computer

　　Some recent developments in the computer industry make scientists predict that the gap between human beings and machines will be closed about the year 20000. To understand the significance of this prediction let us compare the human brain with existing computers. The brain consumes electrical energy at the rate of 25 watts and occupies a volume of one tenth of a cubic foot. The brain houses between 10 billion and 100 billion items of information. Every brain cell is directly connected to many other cells. As a result, the cells in which information is stored can communicate with thousands of other cells. However, the computer consumes 1000,000 watts of electrical power and occupies hundreds of cubic feet of space. Its million items of immediately accessible information. In contrast, the computer memory is like a cell of pigeonholes, with no thinking capacity and no connections elsewhere. In a word, the electronic brains are hopelessly inadequate in comparison with the human brains.

　　13. Health and Life

　　As the saying goes, you dont know what happiness is until you lose it you dont know what health is until you are ill. Health is of vital importance to life sounds like a cliche to everyone, but it is absolutely true. The negligence of the delicate balance of your body and soul, the harmful habits such as smoking, excessive drinking and burning mid-night oil will catch up with you someday. How many big plans are interrupted by bad health! Even a normal life is unimaginable without the guarantee of health. How to keep fit is an eternal topic of diversity and controversy. Regardless of all the different suggestions poured from all kinds of sources, one should do at least two things for him/herself. First, hold an active and optimistic attitude toward life and maintain a mental well-being. Second, live a regular life and keep a balanced diet. Anyway, a healthy life is within reach when you begin to adjust your mind and body.

　　14. Energy Resources

　　China is rich in various energy resources. Coal and petroleum, for instance, are two major ones. They are essential in developing the countrys industry, science and technology. China has done a great deal in the past few decades to raise its output of coal and petroleum. Three energy resources are being used up rapidly, With the building of four modernization, new industrial and science projects are springing up like bamboo shoots after rain. They are all big consumers of energy resources. Besides there has been considerable waste in the utilization of these resources. To avoid an energy crisis in the future, the government must take certain measures. First, it should let people know the importance of saving energy. Second, efforts should be made to develop new energy resources, such as solar energy, geothermal energy and so on. We have reason to be optimistic in this respect.
