1、【题目】The Brain and the Computer

答案：

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 n pigeonholes, with no thinking capacity and no connections elsewhere.In a word, the electronic brains are hopelessly inadequate in comparison with the human brains.

1、【题目】Todayconsumersarefacinganincreasingamountofadvertisingfromcompetingcompanies.Towhatextentdoyouthinkconsumersareinfluencedbyadvertisements?Whatmeasurescanbetakentoprotectthem?

答案：

The extent to which people are influenced by advertisements can be measured in terms of the high sales of popular consumer goods, many of them being unnecessary or completely useless. Mainly through the media, advertisements on products and services are able to penetrate the public mind with half truth and half lying. In many cases, consumers are becoming so greedy that they are not only buying things they really do not need but also spending the money they do not have.

Although advertising gives people a chance as consumers, actually most advertisements tend to cause them to desire for something worthless. Under such circumstances, it is easy to change people's need into greed. So much so, they are constantly encouraged to want things--want this and want that. This human behavior is haunted by the media from all fronts: on radio, on television, and online, not to mention printed circulations such as newspapers and magazines. Obviously, a great number of "impulsive" buyers are persuaded under the illusion that new products or services could make a difference in their lives. Despite all the benefits of the free market economy, the effects of unreliable advertising are particularly negative in that the power of advertising does not reflect the real needs of the society in which products and services are sold.

Worse still, many consumers are convinced to waste money they do not have. Surrounded by advertisements, people are too unwise to perform a balanced act between income and expenditure. Increasingly, what seems to be good for economy begins to backfire because advertising is misleading consumers deeply into commercial debts which they probably could not afford to pay in due time. Thus, instead of improving people's lives, advertising may be considered as a "necessary evil" in modern time. Furthermore, as manufacturing and service companies are competing to have a larger share of the market, it is next to impossible to expect the media to reduce the amount of dishonest advertising. Besides, when it comes to making money, companies and the media are in the same religion.

After all, greed being a human instinct, consumers have only themselves to blame for their foolishness toward advertisements. Since outlawing commercial advertising is out of the question, people should educate themselves to be more prudent in buying and spending behaviors. As for consumers, what better measures can be taken to protect themselves other than self-control?

1、【题目】Insomecountriesaroundtheworldmenandwomentendtohavetheirchildrenlateinlife.Whatarethereasonsforthisdevelopment?Whataretheeffectsonsocietyandfamilylife?

答案：

These days, owing to the advances in biomedical technology, there is a growing tendency in some countries for fresh couples to have children late in their life. From my perspective, this notable trend may associate with women themselves as well as with the increasingly soaring cost of living.

Obviously, women tend to receive longer education in their life span, which means they may get late marriage and consequently have postponed child-bearing. Furthermore, with longer and better education, women may reconsider their role in marriage. To be specific, they may attach more attention to their career trying to be professional in their field, compared with their traditional counterparts mainly performing the role of mother in a family. Apart from the reason coming from women themselves, the high cost of living in some countries may also contribute to this phenomenon. Not only can feeding a family be burdensome for young couples, but offering high quality education for their offspring could be an even more daunting task, which to a large extent hinder their progress to be parents.

Admittedly, having late child-bearing may enable women to fulfill their career ambitions and allow young couples to establish a solid financial base. However, despite the contribution of medical science, late child-bearing may make women be confronted with the pregnancy problems such as low fertility and the high risk of genetic disorder, which could be detrimental to their physical and mental health. Furthermore, postponed child-bearing could also trigger the decline of overall population, which in turn can exacerbate the problem of ageing population, ending up with more pressure on feeding the elderly for our future generations.

To conclude, although having postponed child-bearing could pave the way for women's career development, and enable young couples to better prepare for parents in terms of financial support, the risk of such practice for individuals and society should not be ignored and the analysis seems to indicate its drawbacks outweigh its merits. Thus, government and communities are supposed to do more to help our young couples to get balanced in this issue.

1、【题目】ImportanceofEducation

答案：

China, as a developing country, is determined to catch up with and even surpass the developed ones. I think that one of the best possible ways to do so is to give first priority(优先)to the development of culture, science and especially education.In modern times, when science and technology are making great progress,the education of the work force is of primary importance. Moreover, many of the success in advanced countries have demonstrated that a nation 's prosperity mainly depends on the quality of its labour force,namely those who have been well educated.In a developing country such as China, our investment in culture,education and science, and especially elementary education, must enjoy top priority. This is crucial(决定性的) for China to catch up with the developed nations in today's surging(汹涌的 ) waves of technological revolution. Otherwise, the gap between China and advanced countries will be widened rather than bridged.
