根据以下材料，回答题

Highways

With the increase in auto production， private turnpike （收费公路） companies under local authorities began to spring up， and by 1921 there were 387，000 miles Of paved roads. At that time，

there were no national standards for size， weight restrictions， or weight of trucks. During the World War I， roads throughout the country were nearly destroyed by the weight of trucks. When General Eisenhower returned from Germany in 1919， he noted: "The old convoy （车队） had started me thinking about good， two-lane highways， but Germany"s Autobahn or motorway had made me see the wisdom of broader ribbons across the land."

The interstate highway system was finally started in 1956. To build its 44，000-mile web of highways， bridges， and tunnels， hundreds of unique engineering designs and solutions had to be worked out. Considering the many geographic features of the country such as mountains， steep grades， wetlands， rivers， deserts and plains， innovative designs of roadways began to weave their way across the country， forever altering the face of America.

Today， the interstate system links every major city in the U.S.， and the U.S. with Canada and Mexico. Built with safety in mind， the highways have wide lanes and shoulders， dividing medians，or barriers， long entry and exit lanes， curves engineered for safe turns， and limited access. The death rate on highways is half that of all other U.S. roads （0.86 deaths per 100 million passenger miles compared to 1.99 deaths per 100 million on all other roads）.

By opening the North American continent， highways have enabled consumer goods and services to reach people in remote and rural areas of the country， spurred the growth of suburbs，and provided people with greater options in terms of jobs， access to cultural program， health care，and other benefits. Above all， the interstate system provides individuals with what they cherish most: personal freedom of mobility.

The interstate system has been an essential element of the nation"s economic growth in terms of shipping and job creation: more than 75 percent of the nation"s freight deliveries arrive by truck;and most products that arrive by rail or air use interstates for the last leg of the journey by vehicle.

Not only has the highway system affected the American economy by providing shipping routes， it has led to the growth of spin-off industries like service stations， motels， restaurants， and shopping centers. It has allowed the relocation of manufacturing plants and other industries from urban areas to rural.

National standards for paved roads were in place by 1921. 查看材料

The Truth of American Health Care

Most people would be impressed by the high quality of medicine available to most Americans.

There is a lot of specialization， a great deal of attention to the individual， a vast amount of advanced technical equipment， and intense effort not to make mistakes because of the financial risk which doctors and hospitals must face in the courts if they handle things badly.

But the Americans are in a mess. The problem is the way in which health care is organized and financed. Contrary to public belief， it is not just a free competition system. The private system has been joined a large public system， because private care was simply not looking after the less fortunate and the elderly.

But even with this huge public part of the system， which this year will eat up 84.5 billion dollars——more than 10 percent of the U.S. budget——large numbers of Americans are left out.

These include about half the 11 million unemployed and those who fail to meet the strict limits onincome fixed by a government trying to make savings where it can.

The basic problem， however， is that there is no central control over the health system. There is no limit to what doctors and hospitals charge for their services， other than what the public is able to pay. The number of doctors has shot up and prices have climbed. When faced with toothache， a sick child， or a heart attack， all the unfortunate person concerned can do is pay up.

Two-thirds of the population are covered by medical insurance. Doctors charge as much as they want knowing that the insurance company will pay the bill.

The medical profession has as a result become America"s new big businessmen. The average income of doctors has now reached $100，000 a year. With such vast incomes the tall in the doctor"s surgery is as likely to be about the doctor"s latest financial deal， as about whether the minor operation he is recommending at several thousand dollars is entirely necessary.

The rising cost of medicine in the U.S.A. is among the most worrying problem facing the country.

In 1981 the country"s health cost climbed 15.9 percent——about twice as fast as prices in general.

In the U.S. patients can expect， in medical treatment，__________. 查看材料

A.occasional mistakes by careless doctors

B.a great deal of personal attention

C.low charge by doctors and hospitals

D.stacking nurses and bad services

U.S. to Start $3.2 Billion Chiltd Health Study in January

A study that will cost $3.2 billion and last more than two decades to track the health of100,000 U.S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday.

Officials from the U. S. government&39;s National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.

The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.

Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.

Officials said more than $200 million has been spent already and the study is projected to cost $3.2 billion.

"We anticipate that in the long term, what we learn from the study will result in a significant savings in the nation&39;s health care costs," Dr. Duane Alexander, who heads the NIH&39;s Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.

The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.

Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study.

The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.

The aim of the study is to find new ways to __________. 查看材料

A.conduct research

B.track public health

C.prevent or treat illness

D.speed up development

Cancer Drug Trials Often Halted Early

An increasing number of clinical trials for new cancer treatments are being halted before the risks and benefits have been fully evaluated， say Italian researchers， who warn that this growing trend could put patients at risk of harm from new therapies rushed into use.

The researchers looked at 25 randomized， controlled clinical trials that were stopped early because the treatments had started to show benefit to patients.

"When we analyzed 25 trials over a 10-year period between 1997 and 2007， we found a consistent increase in prematurely stopped trials——more than 50 percent were stopped within the last three years，" study co-author Giovanni Apolone said at a news conference Tuesday.

Of 14 trials halted early and published between 2005 and 2007， the researchers found that 11（79 percent） of them were used to support drug approval applications submitted to the European Medicines Agency and the U.S. Food and Drug Administration.

"This suggests a strong commercial component in stopping trials prematurely. In fact， this strategy could guarantee quicker access to the market for companies. On the other hand， a quicker clinical drug development may lead to an "immature" benefit/risk balance of new drugs，"Apolone said.

He and his colleagues "are aware that trials stopped early because they are showing benefit may result in identification of promising new treatments for patients. However， findings obtained following this strategy should be considered to be preliminary results that require subsequent confmnation."

It can take several years for the long-term benefits or harmful side effects of a new treatment to become apparent， Apolone noted， but the average duration （持续时间） of the 25 studies he and his colleagues analyzed was 30 months， with a range from 12 to 64 months.

They also found that at the time five of the studies were stopped， they"d enrolled less than 40 percent of the total number of patients planned for final analysis.

"Clinical trials need to stop early for superior benefit whenever there"s proof beyond reasonable doubt that the new treatment really is superior. That would be an ethical obligation，"Stuart Pocock， a professor of medical statistics at the London School of Hygiene and Tropical Medicine in the United Kingdom， said at the news conference. "However， too many trials are stopped early claiming efficacy （功效） without strong evidence being available."

The number of prematurely stopped clinical trials has increased recently. 查看材料

New Product Will Save Lives

Drinking water that looks clean may still contain bugs (虫子) , which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Parton, who started Genera five years ago.＜br＞

He and his employees have developed the test together with a British water company.＜br＞

Andy Headland, Genera&39;s marketing director, recently presented the test at a conference in the USA and forecast good American sales for it. Genera has already sold 11 of its tests at $ 42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government. Genera was formed five years ago and until October last year it had only five employees; it now employs 14. Mr. Headland believes that the company should make around $19 million by the end of the year in the UK alone.

根据以下材料，回答题Privacy in the 21st CenturySomeday a stranger will read your e-mail wit

根据以下材料，回答题

Privacy in the 21st Century

Someday a stranger will read your e-mail without your permission or scan the Websites you"ve visited， or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits.

In fact， it"s likely some of these things have already happened to you. Who would watch you without your permission.0 It might be a spouse， a girlfriend， a marketing company， a boss， a cop or a criminal. Whoever it is， they will see you in a way you never intended to be seen——the 21st century equivalent of being caught naked.

Psychologists tell us boundaries are healthy， that it"s important to reveal yourself to friends，family and lovers in stages， at appropriate times. But few boundaries remain. The digital bread crumbs （碎屑） you leave everywhere make it easy for strangers to reconstruct who you are， where you are and what you like. In some cases， a simple Google search can reveal what you think. Like it or not， increasingly we live in a world where you simply cannot keep a secret.

The key question is: Does that matter？ For many Americans， the answer apparently is "no".

When opinion polls ask Americans about privacy， most say they are concerned about losing it.

A survey found an overwhelming pessimism about privacy， with 60 percent of respondents saying they feel their privacy is "slipping away， and that bothers me".

But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths （收费站） to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon （优惠劵） .

But privacy does matter——at least sometimes. It"s like health: When you have it you don"t notice it. Only when it"s gone do you wish you"d done more to protect it.

Why does the author list several cases that your information can be accessed without your permission？查看材料

A.To introduce the topic.

B.To remind the importance of privacy.

C.To inform. what 21 st century is like.

D.To call for the action against the spread of website.
