10. Opening-door Policy is the Only Way to Make China Strong

Modern Chinese history leads us to the conclusion that socialism, not capitalism is best for China. But how a socialist China should look at capitalism and more importantly, make use of the better side of capitalism for its own advantage is of vital(至关） importance to the country.

As far as our country's economic construction is concerned, taking advantage of the part of capitalism that is useful to us means we need to develop foreign trade, introduce advanced technology and better management, and make use of foreign funds. It also means we can absorb some of the economic theories, and make use of those economic policies, methods and measures that comply with(遵循） the law of mass production and a commodity economy.

By opening our windows wider to the outside world, people can learn more about other peoples and learn to make sensible judgments. absorbing the better part of the cultures of other people to enrich ourselves is the best way to safeguard our socialist culture. So taking advantage of capitalism and stepping up economic reforms is the only way to make China strong. Closing the county to international exchanges will only keep it weak.

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(热情） 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.

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.
