单选题Internet Shopping Internet shopping is a new way of shopping. Nowadays, you can shop for just about anything from your armchair. All you need is a computer which is linked to the Internet. Shopping on the Internet is becoming increasingly popular. In the United States, people spent over US $ 2.5 billion on Internet shopping in 1998. This figure is expected to reach US $ 11 billion by the year 2004. People can shop for a variety of products on the Internet. Physical products include items such as books, CDs, clothes and food. These types of products are the most common purchases through the Internet. You can also buy information products such as on-line news or magazine stories, or you can download computer software through the Internet. Services such as booking airline tickets, reserving hotels or renting ears are also available on the Internet. You can also go shopping on the Internet for entertainment services and take part in on-line games. Internet shopping offers a number of benefits for the shopper. The must important advantage is convenience. You can shop whenever you like as the on-line shops are open 24 hours a day and you don't have to queue with other shoppers at the cheek-out counters. Secondly, it is easy to find what you are looking fur on the Internet. Even out-of-print books may be ordered on line. Finally, it is often cheaper to buy goods through the Internet, and you can tell the shop exactly what you want. The main disadvantage of Internet shopping is that you cannot actually see the products you are buying or cheek their quality. Also, many people enjoy shopping in the city and miss the opportunity to talk to friends. Some people are worried about paying for goods using credit cards, so Internet companies are now finding ways to make on-line payment safe. Internet shopping is sure to become more and more popular in the years ahead. It promises to change the way we buy all kinds of things-from tonight's dinner to a new ear.

An Observation and an
Explanation{{/B}} It is worth looking at one or two aspects of the
way a mother behaves towards her baby. The usual fondling, cuddling and cleaning
require little comment, but the position in which she holds the baby against her
body when resting is rather revealing. Careful studies have shown the fact that
80 percent of mothers hold their infants in their left arms, holding them
against the left side of their bodies. If asked to explain the significance of
this preference most people reply that it is obviously the result of the
predominance of right-handedness in the population. By holding the babies in
their left arms, the mothers keep their dominant arm free for manipulations. But
a detailed analysis shows that this is not the case. True, there is a slight
difference between right-handed and left-handed females; but not enough to
provide adequate explanation. It emerges that 83 percent of right-handed mothers
hold the baby on the left side, but so do 78 percent of left-handed mothers. In
other words, only 22 percent of the left-handed mothers have their dominant
hands free for actions. Clearly there must be some other, less obvious
explanation. The only other clue comes from the fact that the
heart is on the side of the mother's body. Could it be that the sound of her
heart beat is the vital factor? And in What way? Thinking along these lines it
was argued that perhaps during its existence inside the body of the mother the
unborn baby get used to the sound of the heart beat. If this is so, then the
re-discovery of this familiar sound after birth might have a claiming effect on
the infant, especially as it has just been born into a strange and frighteningly
new world, if this is so then the mother would, somehow, soon arrive at the
discovery that her baby is more at peace if held on the left against her heart
than on the right.
单选题Alzheimer"s Disease
It was a big week for Alzheimer"s disease, and not just because PBS aired The Forgetting, a first-rate documentary about Alzheimer"s worth catching in reruns if you missed it the first time. There was also a flurry of scientific news that offered hope to the families already struggling with Alzheimer"s, as well as to the baby-boom generation that"s up next. Unless something dramatic happens, the number of Americans living with this terrifying brain disease could triple, to about 16 million, over the next 50 years. There"s still no cure in sight, but there is progress on several fronts. Among them:
MEGADOSE VITAMINS—Doctors knew vitamins E and C, both antioxidants, help stave off Alzheimer"s, at least in folks who haven"t already developed the disorder. What they didn"t know—but a big study involving 4,740 participants published in the Archives of Neurology showed—was that the two vitamins taken together in huge daily doses (at least 400 IU of E and more than 500 mg of C) could reduce the risk of Alzheimer"s a remarkable 78%.
COMBINATION THERAPY—A yearlong study of more than 400 Alzheimer"s patients showed that two drugs that work differently on the brain"s chemistry act well together to help slow down the disease. Patients who were being treated with donepezil (sold as Aricept), an older drug that preserves the neurotransmitter acetylcholine, were also given memantine (Namenda), a new drug approved by the FDA last October that blocks overproduction of a harmful brain chemical called glutamate. The two drugs worked even better in combination than they did alone, providing substantial benefit for patients with moderate to severe Alzheimer"s, according to a report in the Journal of the American Medical Association.
BRAIN IMAGINC—Finally, scientists at the University of Pittsburgh announced that they had successfully developed a procedure that allows them to peer into the brains of Alzheimer"s patients with positron emission tomography (PET) scans to see telltale plaque deposits. Before now, doctors could not track the progress of these plaques until after the patient died, when the brain could be autopsied. Using the new technique, doctors may be able to begin treatment long before the first symptoms appear.
None of these advances is a magic bullet for Alzheimer"s disease. If you or your loved ones are concerned, the first step is careful evaluation by your doctor. Not all memory lapses are Alzheimer"s, and there are reversible causes of forgetfulness that can be treated if caught early. Also, remember the old adage "use it or lose it." Mental exercise—reading, doing crossword puzzles, playing chess or scrabble—is as good for preserving your mind as physical exercise is for your body.
单选题Is the Tie a Necessity?
Ties, or neckties, have been a symbol of politeness and elegance in Britain for centuries. But the casual Prime Minister Tony Blair has problems with them. Reports suggest that even the civil servants may stop wearing ties. So, are the famously formal British really going to abandon the neckties?
Maybe. Last week, the UK"s Cabinet Secretary Andrew Turnbull openly welcomed a tieless era. He hinted that civil servants would soon be free of the costliest 12 inches of fabric that most men ever buy in their lives.
In fact, Blair showed this attitude when he had his first guests to a cocktail party. Many of them were celebrities (知名人士) without ties, which would have been unimaginable even in the recent past.
For some more conservative British, the tie is a must for proper appearance. Earlier, Labor leader Jim Callaghan said he would have died rather than have his children seen in public without a tie. For people like Callaghan, the tic ; was a sign of being complete, of showing respect. Men were supposed to wear a tie when going to church, to work in the office, to a party-almost every social occasion.
But today, people have begun to accept a casual style even for formal occasions.
The origin of the tie is tricky. It started as something called simply a "band". The term could mean anything around a man"s neck. It appeared in finer ways in the 1630s. Frenchmen showed a love of this particular fashion statement. Their neckwear (颈饰) impressed Charles Ⅱ, the king of England who was exiled (流放) to France at that time. When he returned to England in 1660, he brought this new fashion item along with him.
It wasn"t, however, until the late 18th century that fancy young men introduced a more colorful, flowing piece of cloth that eventually became known as the tie. Then, clubs, military institutions and schools began to use colored and patterned ties to indicate the wearer"s membership in the late 19th century. After that, the tie became a necessary item of clothing for British gentlemen.
But now, even gentlemen are getting tired of ties. Anyway, the day feels a bit easier when you wake up without having to decide which tie suits you and your mood.

单选题Bringing Nanotechnology to Health Care for the Poor Nanotechnology uses matter at the level of molecules and atoms. Researchers are finding different uses for particles with a length of one nanometer, or one-billionth of a meter. These include things like beauty products and dirt-resistant clothing. But one area where many experts believe nanotechnology holds great promise is medicine. Last week, speakers at a program in Washington discussed using nanotechnology to improve health care in developing countries. The program took place at the Woodrow Wilson International Center for Scholars. Peter Singer at the University of Toronto says a nanotechnology called quantum dots could be used to confirm cases of malaria. He says it could offer a better way than the traditional process of looking at a person's blood under a microscope. In poor countries, this process is often not followed. As a result, sick people may get treated for malaria even if they do not have it. Such misuse of medicines can lead to drug resistance. Quantum dots are particles that give off light when activated. Researchers are studying ways to program them to identify diseases by lighting up in the presence of a targeted molecule. Experts say nanotechnology shows promise not just for diagnosing diseases, but also for treating them. Piotr Grodzinski of the National Institutes of Health talked about how nanotechnology could make drugs more effective. He talked about cancer drugs already developed with nanotechnology. He says if a drug can target a cancer locally in the body, then much less of it might be needed, and that means lower side effects. Andrew Maynard is chief scientist for the Project on Emerging Nanotechnologies at the Woodrow Wilson Center. He noted that Brazil, India, China and South Africa are currently doing nanotechnology research that could help poor countries. But he also noted that there is some risk in using nano-materials. He says nanometer-sized particles behave differently in the body and the environment compared to larger particles. Experts say more investment in research is needed to better understand these risks.

{{B}} Middle Age: A Low Point for Most{{/B}}
People around the globe hit the height of their misery and depression
in{{U}} (51) {{/U}}age, a new international study suggests.
The finding by British and American researchers was based on an analysis
of well-being among approximately 2 million people in 80 nations. With few
exceptions, the observation appears to apply across the board, regardless{{U}}
(52) {{/U}}gender (性别), culture, geography, wealth, job history,
education, and marriage or parental status. "The scientific
fact seems to be that happiness and positive mental health follow a giant
'U'{{U}}(53) {{/U}}through life," said study author Andrew J.
Oswald, a professor of economics at Warwick University in Warwickshire, England.
"For the average person, it's high when you're 20, and then it slowly falls and
bottoms out{{U}} (54) {{/U}}your 40s. But the good news is that your{{U}}
(55) {{/U}}health picks up again, and eventually gets back to the high
levels of our youth."The finding was {{U}}(56) {{/U}}on the pooling
of several different sources of happiness data, including: two multi-decade
happiness/satisfaction surveys (first launched in the 1970s), involving about
500,000 American and Western European men and women; four rounds of the
80-nation "World Values Survey"{{U}} (57) {{/U}}between 1981 and 2004 in
North America, Eastern and Western Europe, Asia, Africa, Australia, and Central

as-yet unexplained{{U}} (60) {{/U}}differences were observed ,with
happiness among men dipping the most in their early 50s,whereas women hit their
nadir (最低点) around the age of 40. The researchers cautioned that
cheerful people tend to live longer than unhappy{{U}} (61) {{/U}}—a fact
that might have skewed (使偏斜) the overall finding. But they also suggested that
evidence of a happiness{{U}} (62) {{/U}}might simply reflect a midlife
choice to give up long-held but no longer tenable (守得住的), aspirations(志向),
follwed by a senior's sense of gratitude for having successfully endured{{U}}
(63) {{/U}}others did not. "That said, some might find
it helpful simply to understand the general{{U}} (64) {{/U}}of mental
health as they go through their own life," said Oswald. "It might be useful for
people to realize that if they are{{U}} (65) {{/U}}in their 40s this is
normal. It is not exceptional. And just knowing this might
help."
