Read the following paragraph about animal testing and answer the questions. Many people believe that animal testing should not be forbidden since it has contributed to many life-saving cures and treatments. The California Biomedical Research Association states that nearly every medical breakthrough in the last 100 years has resulted directly from research using animals. For example, experiments in which dogs had their pancreases removed led directly to the discovery of insulin, critical to saving the lives of diabetics. Chris Abee, Director of the University of Texas M.D. Anderson Cancer Center's animal research facility, states that "we wouldn't have a vaccine for hepatitis B without chimpanzees," and says that the use of chimps is "our best hope" for finding a vaccine for Hepatitis C, a disease that kills thousands of Americans annually. 1. How many sources are cited？
A、One.
B、Two.
C、Three.
D、Zero.

How to live to 100
A growing body of research suggests that chronic illness is not an inevitable consequence of aging, but more often the result of lifestyle. choices. "People used to say, 'who would want to be 1007TM says Dr. Thomas Peris, an instructor at Harvard Medical School and director of the New England Centenarian Study. "Now they're realizing it's an opportunity." High-tech medicine isn't likely to change the outlook dramatically; drugs and surgery can do only so much to sustain a body once it starts to fail. But there is no question we can lengthen our lives while shortening our deaths. The tools already exist, and they're within virtually everyone's reach.
Life expectancy in the United States has nearly doubled since a century ago —from 47 years to 76 years. And though centenarians are still rare, they now constitute the fastest-growing segment of the U.S. population. Their ranks have increased 16-fold over the past six decades —from 3,700 in 1940 to roughly 61,000 today. The Census Bureau projects that 1 in 9 baby boomers (9 million of the 80 million people born between 1946 and 1964) will survive into their late 90s, and that 1 in 26 (or 3 million) will reach 100. "A century ago, the odds of living that long were about one in 500." says Lynn Adler, founder of the National Centenarian Awareness Project and the author of "Centenarians: The Bonus Years." "that's how far we've come."
If decrepitude were an inevitable part of aging, these burgeoning numbers would spell trouble. But the evidence suggests that Americans are living better, as well as longer. The disability rate among people older than 65 has fallen steadily since the early 1980s, according to Duke University demographer Kenneth Manton, and a shrinking percentage of seniors are plagued by hypertension, arteriosclerosis and dementia. Moreover, researchers have found that the oldest of the old often enjoy better health than people in their 70s. The 79 centenarians in Perls's New England study have all lived independently through their early 90s, taking an average of just one medication. And when the time comes for these hearty souls to die, they don't linger. In a 1995 study, James Lubitz of the Health Care Financing Administration calculated that medical expenditures for the last two years of life —statistically the most expensive —average ＄ 22, 600 for people who die at 70, but just＄ 8,300 for those who make it past 100.
These insights have spawned a revolution in the science of aging. "Until recently, there was so much preoccupation with diseases that little work was done on the characteristics that permit people to do well." says Dr. John Rowe, the New York geriatrician who heads the MacArthur Foundation's Research Network on Successful Aging. Research confirms the old saying that it pays to choose your parents well. But the way we age depends less on who we are than on how we live — what we eat, how much we exercise and how we employ our minds.
The author seems to suggest that ______.
A．the aged should not go to the nursing home
B．we can lengthen our lives through high-tech medicine
C．centenarians die faster than those who arc younger
D．the ever-growing segment of centenarians has caused concern

The lottery money is supposed to go to charity--but it makes me angry to see some of the so-called "good causes" it's being used to support. Also, Camelon, the organizers, have made a profit of ￡10.8 million in five months. We hear now that a lot of that money is boosting the pay packets of the company's bosses.
For the past 10 years I've been helping to raise funds for a cancer research charity called Tenovus. My husband, Sandy, died from cancer 11 years ago--he was only 51. There's been a long line of deaths in our family through cancer and it's been devastating. I've also lost two sisters-in-law, my brother, Michael, my father-in-law and my father. That's apart from several close friends.
The charity is 50 years old now and raises money mainly for breast cancer research. It also runs a support line for the families of cancer sufferers. Our local group raises money through dances, sales and coffee mornings, and all the funds go directly to cancer research. In 1993 Tenovus raised￡3 million--and half that money came from sales of our own lottery tickets at supermarkets. But our income has dropped by half since the National Lottery was introduced.
I'm not against people playing the National Lottery, but they should think about what they're doing. The chances of winning the jackpot are so small; they might as well throw their money away. The government tells us that the proceeds are going to things like the arts and sports, but what about the National Health Service？ They should give some cash to that, too. How can they justify spending ridiculous amounts of cash on so-called works of art--like displays of pictures--or buying up Winston Churchill's papers at a cost of ￡12 million？
So who really are the winners in the National Lottery？ When I think of all that money people could be donating to cancer research, I could weep. It's time people realized how charities across the country are suffering because of the National Lottery. It's disheartening and so infuriating.
The writer seems to hope that ______.
A．people will spend more money on the National Lottery
B．people will give more money to charity
C．most of the lottery money will be used for cancer research
D．most of the lottery money will go to charity

Should the U.S. halt human space flight？
The Columbia accident has revived the debate on whether the rewards of human space exploration are worth the risks.
No. I was a teacher when men first landed on the moon in 1969, and I remember how it moved my students and this country.___________(46) And we haven't ventured outward since then. That's 30 years too long! America's human space-flight program is adrift, with no clear vision or goals beyond the completion of the International Space Station.

An astronaut is today's Christopher Columbus, who sailed into the unknown and discovered the Americas. The knowledge we gain from having actual people exploring can never be replaced by robots.___________ (48) Robots are useful, but humans can do things that robots can't.
The real obstacle we face in overcoming the drift in the nation's human space-flight program is not technological and it's not financial.___________ (49)The lesson from the Columbia accident is not that humans don't belong in space.___________ (50)
A．Instead, we should honor the memory of the lost astronauts by pushing our exploration of space future.
B．Astronauts are key to this expanded exploration.
C．It's the lack of commitment to get started.

F．Our ability to send humans into space and have them return gives us amazing information about ourselves and our universe.
第 46 题 请选择（46）处的最佳答案．
Sudan 1 is a red industrial dye that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003.
Since the ban was put in place, EU officials have been striving to remove some food products from the shelves. So far 580 products have been recalled. Last week Sudan's Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification of the origin of the dye's name.
Omaima Mahmoud A1 Sharief, a press official at Sudan's Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye.
"We want to keep an eye on every detail and avoid any misunderstanding there," she said. "Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country. But they told us there was no relationship."
The FSA, an independent food-security watchdog in Britain, received a letter from the Sudan's Embassy last week.
"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said. "People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any explanation before we find out."
Sudan dyes, which include Sudan 1 to 4, are red dyes used for coloring solvents, oils, waxes, petrol, and shoe and floor polishes. They are classified as carcinogens by the International Agency for Research on Cancer.
