Recently the World Health Organization announced that the disease of
smallpox（天花）had almost been wiped out in most parts of the world, thanks to widespread vaccination（种牛痘）. Most people are vaccinated at least once in their lives and if they wish to travel from one country to another they must be able to prove that they have had a recent vaccination. In this way the disease has been prevented from spreading and today one seldom hears of it at all.
This is mainly because of the great discovery made by a village doctor, Edward
Jenner, in about 1798 when he published his report of his new experiment called vaccination (from the word ‘vacca’ meaning a cow). Jenner discovered that people who worked with cattle often suffered from a harmless disease which they caught from the cattle, but these people never seemed to get smallpox. So he experimented by putting the disease into a small opening on the arms of healthy people, and though their arms became painful for a day or two, they soon recovered and none of these people ever got smallpox.
So the news of the wonderful discovery spread to other countries and people
rushed to their doctors to be vaccinated. In many countries the simple way to deal with the arm was done on thousands of people, and the terrible smallpox began to disappear.

Some of the best-known names in the entertainment industry have taken part in an unprecedented telethon to help victims of the terrorist attacks in the United States.

The benefit(义演), called “America: a Tribute to Heroes,” was sponsored by all four major U.S television networks, ABC, CBS, FOIX and NBC. It was broadcast by three-dozen television, cable and radio networks across the country and aired live to more than a hundred countries around the world.

Hollywood stars joined music entertainers in asking listeners and viewers to pledge cash donations to charities helping the victims of the September 11^th attacks.

Actors, including Tom Hanks, Julia Roberts, Tom Cruise and Clint Eastwood, told stories of heroic acts by people who tried to save others from the burning World trade Center and the Pentagon. Former heavyweight champion Muhammad Ali made a rare public appearance in show of support.

The appeals alternated with performances by such popular entertainers as Bruce Springsteen, Mariah Carey, Steve Wonder, Paul Simon and the rock band U—2.

They appeared on stages in New York, Los Angeles and London, decorated with hundreds of burning candles.

Singer Billy Joel sang “ New York State of Mind” with a New York City firefighter’s hat on his piano. Sting dedicated his song “ Gragile” to a friend who died in the World Trade Center. Stevie Wonder condemned(指责) hatred in the name of religion before singing his song “ Love’s in Need of Love today”. Pledge phones were manned by dozens of other celebrities, including Jack Nicholson, Meg Ryan, Whoopic Goldberg, Cindy Crawford, Al Pacino and Sylvester Stallone.

Organizers say the two-hour telethon raised millions of dollars. All participants, from stars to stagehands, worked without pay.

America is growing older. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10 out of every 100 Americans are over 65. The aging of the population will affect American society in many　ways — edu??cation, medicine, and business. Quietly, the aging of America has made us a very different society — one in which people have a quite different idea of what kind of behavior is suitable at various ages.

A person’s age no longer tells you anything about his/ her social position, marriage or health. There’s no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop work??ing isn’t as strong as it used to be. It doesn’t surprise us to hear of a 29-year-old university president or a 35-year-old grandmother, or a 70-year-old man who has become a father for the first time. Public ideas are changing.

Many people say, “I am much younger than my mother or my father was at my age.” No one says “Act your age” any more. We’ve stopped looking with surprise at older people who act in youthful ways.

It can be learned from the text that the aging of the popula??tion in America ________.

A. has made people feel younger

       B. has changed people’s social position

C. has changed people’s understanding of age

D. has slowed down the country’s social development

The underlined word “one” refers to ________.

A. a society           B. America          C. a place           D. population

“Act your age” means people should ________.

A. be active when they are old

B. do the right thing at the right age

C. show respect to their parents young or old

D. take more physical exercises suitable to their age

f a’ 25-year-old man becomes general manager of a big firm, the writer of the text would most probably consider it _________.

A. normal      B. wonderful         C. unbelievable     D. unreasonable

Simply by analyzing a drop of blood, a doctor will be able to diagnose a birth defect or even cancer when it is in the early stage; using new technology, a material lighter but much stronger than steel can be produced.
These may sound like dreams at present. But the dreams may soon come true as research findings in laboratories are being turned into products more rapidly in the new century, according to experts participating in the fourth Asia-Pacific Economic Cooperation (APEC) Technomart, a technology exhibition and trade fair in Suzhou.　　
"Most people think nano-technology（纳米技术）is too far-fetched to be real. But in fact nano-technology has been applied in a wide range of fields, such as medicine. It is coming into our daily life," said Cheng Jiachong from a Hong Kong-based nano-technology firm.
Nano-technology based on the nanometer, the unit of which is a billionth of a meter, enables scientists to have new concepts of disease diagnosis and treatment on a molecular（分子）and atomic scale, Cheng said.　　
By using nanometer particles, a doctor can separate the fetus cells（胚胎细胞）from the blood of a pregnant woman to see if the development of the fetus is normal. This method is also being used in the early diagnosis of cancer and heart disease, he said.　　
One of the most significant impacts of nano-technology is at the bio-inorganic materials interface, according to Greg Tegart, executive advisor of the APEC Center for Technology Foresight.　　
"By combining enzymes（酶）and silicon chips we can produce biosensors. These could be implanted in humans or animals to monitor health and to deliver corrective doses（剂量）of drugs," he told the participants a technology forum during the exhibition.　　
"Nano-technology could affect the production of nearly every man-made object, from automobiles, tires and computer circuits（电路）, to advanced medicines and tissue replacement, and lead to the invention of objects yet to be imagined," said David Minns, a special advisor to the National Research Council of Canada.　　
It has been shown that carbon nano-tubes are ten times as strong as steel, with one sixth of the weight, and nano-scale systems have the potential to make supersonic transport cost- effective and to increase computer efficiency by millions of times, he said.
The experts agreed that the APEC technology exhibition and trade fair provided many chances for exchanges of innovative ideas and products.
【小题1】Realization of the dreams mentioned in the first paragraph will mainly base on ________.

A．meter

B．meter

C．meter

D．meter
