Intelligence: A Changed View
1. Intelligence was believed to be a fixed entity (存在，实体), some faculty of the mind that we all possess and which determines in some way the extent of our achievements. Its value, therefore, was as a predictor of children&39;s future learning. If they differed markedly in their ability to learn complex tasks, then it was clearly necessary to educate them differently and the need for different types of school and even different ability groups within school was obvious. Intelligence tests could be used for streaming(分流，分组) children according to ability at an early age. And at 11 these tests were superior to measures of attainment for selecting children for different types of secondary education.
2. Today, we are beginning to think differently. In the last few years, research has thrown doubts on the view that innate (内在的) intelligence can ever be measured and on the very nature of intelligence itself. There is considerable evidence now shows the great influence of environment both on achievement and intelligence. Children with poor home backgrounds not only do less well in their school work and intelligence tests but their performance tends to deteriorate gradually compared with that of their more fortunate classmates.
3. There are evidences that support the view that we have to distinguish between genetic intelligence and observed intelligence(习得智力). Any deficiency in the appropriate genes will restrict development no matter how stimulating the environment is. We cannot observe and measure innate intelligence, whereas we can observe and measure the effects of the interaction of whatever is inherited with whatever stimulation has been received from the environment. Researchers have been investigating what happens in this interaction(相互作用).
4. Two major findings have emerged from these researches. Firstly, the greatest part of the development of observed intelligence occurs in the earliest years of life. It is estimated that 50 percent of measurable intelligence at age 17 is already predictable by the age of four. Secondly, the most important factors in the environment are language and psychological aspects of the parent-child relationship. Much of the difference in measured intelligence between "privileged" and "disadvantaged" children may be due to the latter&39;s lack of appropriate verbal stimulation and the poverty of their perceptual (感性的) experiences.
5. These research findings have led to a revision in our understanding of the nature of intelligence. Instead of it being some largely inherited fixed power of the mind, we now see it as a set of developed skills with which a person copes with any environment. These skills have to be learned and, indeed, one of them is learning how to learn.
6. The modern ideas concerning the nature of intelligence are bound to have some effect on our school system. In one respect a change is already occurring. With the move toward comprehensive education and the development of unstreamed classes, fewer children will be given the label "low IQ(智商, Intelligence Quotient)" which must inevitably condemn a child in his own, if not society&39;s eyes. The idea that we can teach children to be intelligent in the same way that we canteach them reading or arithmetic is accepted by more and more people.

Intelligent Machines
1．Medical scientists are already putting computer chips(芯片)directly into the brain to help people who have Parkinson&39;s disease，but in what other ways might computer technology be able to help us？ RayKurzweil is author of the successful book The Age of Intelligent Machines and is one of the world&39;s best computer research scientists．He is researching the possibilities．
2．Kurzweil gets computers to recognize voices．An example of this is Ramona，the virtual(虚拟的) hostess of Kurzweil&39;s homepage，who is programmed to understand what you say．Visitors to the site can have their conversations with her，and Ramona also dances and sings．
3．Kurzweil uses this technology to help people with physical disabilities．One of his ideas is a“seeing machine”．This will be“like a friend that could describe what is going on in the visible world”，he explains．Blind people will use a visual sensor(探测器)which will probably be built into a pair of sunglasses．This sensor will describe to the person everything it sees．
4．Another idea，which is likely to help deaf people，is the“listening machine”．This invention will recognize millions of words and understand any speaker．The listening machine will also be able to translate into other languages，80 even people without hearing problems are likely to be interested in using it．
5．But it is not just about helping people with disabilities．Looking further into the future，Kurzweil sees a time when we will be able to download our entire consciousness onto a computer．This technology probably won&39;t be ready for at least 50 years，but when it arrives，it means our minds will be able to live forever．

第7题
2. There are more than 70 clinically useful antibiotics, Antibiotics fight pathogenic microbes and cancer cells by interfering with their normal cell processes. In most cases, this interference can occur in one of three ways: prevention of cell wall formation, disruption of the cell membrane, and disruption of chemical processes.
3. The contents of bacterial cells are enclosed in a membrane that is surrounded by a rigid wall that prevents the cells from splitting open. Penicillins and some other antibiotics destroy pathogenic microbes by hindering the formation of this wall. Human cells do not have nor need rigid cell walls and so are not damaged by these antibiotics.
4. Some antibiotics, including nystatin, disrupt the cell membrane of certain microbes. This membrane controls the movement of materials in and out of the cell. If the membrane is disrupted, vital nutrients may escape from the cell, or poisonous substances may enter and kill the cell. But the membranes of human cells are not affected because these antibiotics disrupt cell membranes that contain elements found only in microbial cells.
5. All cells produce proteins and nucleic acids, which are vital to the life of any organism. Some antibiotics fight disease by interfering with the chemical processes by which these substances are produced.For example, streptomycin prevent certain kinds of microbes from producing proteins, and rifampin interferes with the formation of nucleic acids. Human cells produce proteins and nucleic acids in much the same way that microbial cells do. But these processes differ enough so that some antibiotics interfere with chemical activities in microbial cells but not in human cells.

Nystatin is used to disrupt the wall surrounding the membrane. F. Some antibiotics fight disease by interfering with chemical activities in microbial cells but not in human cells.

Waste Not，Want Not
1．Bob and Clara Darlington，who own and run a farm in the North of England，have always looked for new ways of making money out of the produce they grow．Their success began when they established a shop on their farm，so that people could come and buy fresh vegetables directly from them．
2．The business was an immediate Success，and soon scored top marks in a competition set up by the Farm Retail Association to find the best farm shop in the country．The Association&39;s inspectors found the Darlingtons&39; shop offered excellent service and value for money as well as quality fruit and vegetables．
3．Clara Darlington is a trained chef and，in addition to a range of home-grown foods and other local produce，she began offering a variety of prepared meals which she had made herself in the farmhouse kitchen．A small care alongside the farm shop was soon added，with everything that visitors could taste on the menu also being for sale in the shop．
4．Clara admits that starting the business was expensive，and she has worked very hard，but maintains that if the product is good，the public recognize this and buy jt．“I aim to offer the highest quality to our customers，whether they come in for a loaf of bread，or take a whole dinner-party menu．I take it as a compliment(恭维) if people take home one of my dishes to serve to their family and friends and get away with pretending they made it themselves．”
5．So it was that the couple realized that they had a surplus of misshapen or damaged vegetables grown on the farm which were unsuitable for selling in the shop．Clara，not wishing to see them get thrown away，decided to turn them into soup．
6．The soup met with the immediate approval of customers to the shop and Clara now produces ten different varieties．She spent much of the summer traveling up and down to London by rail，doing presentations of the soups．As a result，they are now served in first-class railway restaurant cars belonging to three companies as well as being stocked by a number of high-class London stores．
