Nanotechnology

Many of the grand challenges of today and the future are found in the question: "How are we going to solve the problems and make serious improvements in industrial manufacturing, disease control, environmental pollution control, global climate change, food production, transportation, communication, and others？"

Nanotechnology (纳米技术 ) promises to make revolutionary contributions.Within the next few years we can expect to see major improvements. Here are some possibilities the things to come.Nanotechnology is fundamentally changing the way materials and devices will be produced in the future.

Nanostructures, ceramics, polymers, metals, and other materials will have greatly improved mechanical properties.In fact, with the ability to build things atom-by-atom and molecule-by-molecule there will be new classes of structural materials.Nanotechnology will enable products to be lighter, stronger, smarter, cheaper,cleaner, and more precise.

The ability to synthesize nanoscale budding blocks with precisely controlled size and composition and then to assemble them into larger structures with unique properties and functions will revolutionize segments of the materials manufacturing industry. Nanotechnology is expected to bring about lighter, stronger, and programmable materials ; reductions in life-cycle costs through lower failure rates; innovative devices based on new principles and architectures ; and use of molecular cluster manufacturing.

Nanotechnology will provide new tools for medicine.It could radically change the way surgery is done.It will make it possible to do molecular scale surgery to repair and rearrange cells.Since disease is the result of physical disorder, misarranged molecules and cells, medicine at this level should be able to cure most diseases.

Mutations in DNA could be repaired and cancer cells, toxic chemicals, and viruses could be destroyed through use of medical Nan devices.

Nanotechnology enabled increases in computational power will permit the characterization of macromolecular networks in realistic environments.Such simulations will be essential elements in the development of biocompatible implants and in the drug discovery process. Nanotechnology has the potential to significantly impact energy efficiency, storage, and production, Nanotechnology can change the economics of energy production.

The passage deals mainly with__________. 查看材料

A.grand challenge in manufacturing， medicine and computer industry

B.possibilities of nanotechnology"s contributions in the future

C.great changes caused by nanotechnology

D.practical application of nanotechnology

Government Policies and Economy

While he was off on his l978 tour，Americans were becoming disgusted with their lot as all“emerging second—class nation”，Wilson says．They began to see that incentives had to be restored to the economy．For instance，the capital gains tax was cut，an extraordinary turn—about．If it had been predicted before he went away in May，he would have said it was simply inconceivable as inconceivable as the prospect of Resorts going up1，000 percent．

This momentous transformation in the U．S．should soon bring about a huge bull market． In the l940s and l950s，the last time price earning multiples were at these low levels，the investing public expected that there would be another great postwar depression．Instead，aRer the beginning of l953 it became apparent that there would not be one，and price-earnings multiples got so low this time that investors felt that the country was drifting into socialism．That drift，however，may be reversing direction．

Wilson believes that the bankruptcy of New York City means the discrediting of big government，that as a result there will be less government，and that things in general will go much better．From l980’s depressed levels the market could rise to twenty times doubled earnings or almost fivefold in five to seven years．Wilson believes that he’ll be worth hundreds of millions of dollars before it’s over．

From paragraph l，we can infer that Resorts is__________． 查看材料

阅读材料，回答题。

Breakfast

Studies show that children who eat breakfast do better in school. It doesn&39;t take much further thought to believe that adults will feel better and perform. better at work as well .Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to skip (故意略去 ) breakfast.

If we don&39;t eat breakfast, we are likely to become tired when our brains and bodies run low on fuel. By mid-morning, a lot of us grab a cup of coffee, or wolf down a sugary candy bar to wake up again. This might work for a few minutes, but by lunchtime we are hungry, bad-tempered, and perhaps our mood might make us a little more likely to make unhealthy choices at lunch. Eating a good breakfast sets the tone for the rest of the day.

People who eat breakfast are generally more likely to maintain a healthy weight. Many people believe that they will lose weight if they skip meals, but that isn&39;t a good idea. The body expects to be refueled a few times a day, so start with a healthy breakfast.

A healthy breakfast should contain some protein (蛋白质) and some fiber (纤维) . Protein can come from meat, eggs, beans, or soy (大豆) . Fiber can be found in whole cereals (谷物), grains or in fruits.A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with soy milk.

Adults who eat breakfast will perform. better at work. 查看材料

A.Right

B.Wrong

C.Not mentioned

阅读材料，回答题：

Understanding Autism

1 Autism (孤独症) is a life-long developmental disability that prevents individuals from properly understanding what they see, hear, and otherwise sense. This results in severe problems of social relationships, communication, and behavior. Individuals with autism have to painstakingly (费力地) learn normal patterns of speech and communication, and appropriate ways to relate to people, objects, and events, in a similar manner to those who have had a stroke.

2 The cause of autism is still unknown. Some research suggests a physical problem affecting those parts of the brain that process language and information coming in from the senses. There may be some imbalance of certain chemicals in the brain. Genetic (遗传的 )factors may sometimes be involved. Autism may indeed result from a combination of several "causes"

3 Most people with mental retardation (智力迟钝)show relatively even skill development. Indi- viduals with autism, however, typically show uneven skill development, with deficits (欠缺)in cer- tain areasmmost frequently in their ability to communicate and relate to others--and distinct skills in other areas. It is important to distinguish, autism from mental retardation or other disorders,.&

since diagnostic (诊断的)confusion may lead to inappropriate and ineffective treatment tech- niques.

4 In general, individuals with autism perform. best at jobs which are structured and involve a de- gree of repetition. Some people who have autism are working as artists, piano tuners, painters, farm workers, office workers, computer operators, dishwashers, assembly line workers, or employees of sheltered workshops or other sheltered work settings.
