Seasonal influenza is characterized by a sudden fever, cough, headache, muscle and joint pain, sore throat and runny nose. Most people recover from fever and   1  symptoms within a week without requiring medical attention. But influenza can  2  severe illness or death in people at high risk. The time from infection to illness is about two days.

Yearly influenza epidemics can  3   affect all age groups, but the highest risk of complications occur among children younger than age two, adults age 65 or older, and people of  4   age with certain medical conditions, such as chronic heart, lung, kidney, liver, blood or metabolic diseases, or weakened immune systems.

Seasonal influenza  5   easily and can sweep through schools, nursing homes or businesses and towns. When an   6    person coughs, infected droplets get into the air and another person can breathe them  7    and be exposed. The virus can also be spread by hands infected with the virus.  8    transmission, people should cover their mouth and nose with a tissue when coughing, and  9   their hands regularly.

Drugs for influenza are   10   in some countries and effectively prevent and treat the illness. Some influenza viruses develop  11    to the antiviral medicines, limiting the effectiveness of treatment.

Influenza epidemics occur    12   during autumn and winter in temperate regions. Illnesses result in hospitalizations and deaths mainly among high-risk groups. Worldwide, these annual epidemics result in about three to five million   13     of severe illness, and about 250 000 to 500 000 deaths.

Influenza can cause serious public health and economic problems. In   14    countries, epidemics can result in high levels of worker absenteeism and productivity   15   .   16    most people recover from a bout(轮) of influenza, there are large numbers of people who need hospital treatment and many   17    die from the disease every year.   18     is known about the effects of influenza epidemics in developing countries.

The most    19   way to prevent the disease or severe outcomes from the illness is vaccination. Vaccination is especially important for people at higher risk of serious influenza complications, and for people who live with or care  20    high risk individuals.

请阅读下列科技新闻的信息:

A. One of the biggest science stories last year was the research on stem cells announced by South Korean scientist Hwang Woo-suk. But now it appears that the research was false. In June, Mr. Hwang reported that he and his team at Seoul National University had created eleven new stem cell lines.

B. Another major science story last year came from the United States. On December twentieth, a federal judge ruled that teaching “intelligent design” in public schools is a violation of the United States Constitution.

C. There was also news last year about the American space program. The American space shuttle(航天飞机) returned to the skies in July. Discovery and its seven-member crew made the first shuttle flight in two and one-half years. NASA had suspended shuttle flights following the deadly explosion of the shuttle Columbia in 2003.

D. Avian influenza(禽流感) was also a major science story last year. The H5N1 virus appeared in birds in Europe for the first time. Yet the only known human cases of the disease have been in East Asia. There have been about one hundred forty confirmed cases of bird flu since 2003. About half the people have died.

E. The World Health Organization advises patients to take a combination of four drugs to treat tuberculosis(肺结核). These four antibiotics must be taken for about six months to cure the disease. Some people, however, take the drugs only until they feel better. Discontinuing treatment is a mistake.

F. The researchers began the study in January, 2002. They called it SMART---Strategies for Management of Anti-retroviral Therapy. The scientists reached more than ninety percent of the target before they halted(停止) new enrollments last month. The researchers tested all the people for the level of CD-four cells in their blood. The researchers divided the patients into two groups.

阅读以下与科技有关的信息卡,然后匹配信息卡和与之相关的科技新闻:

1.Card 1: One group stayed on continuous anti-retroviral therapy. They took their medicines every day. The other took them periodically. They took the drugs only when their CD-four count fell below two hundred fifty cells per cubic millimeter of blood.

2.Card 2 : Judge John Jones said that intelligent design is not science. He said it is a version of Christianity. So to teach it in public schools violates the law that requires the separation of church and state. Supporters of intelligent design criticize the science of evolution.

3.Card 3: Stem cells have the ability to grow into other cells. Science magazine published the report. The new lines were made from the eggs of eighteen women and skin cells from eleven other people.

4.Card 4: Many of the victims had touched or been around infected farm birds. But health experts around the world began warning that the bird flu virus could change into a form that is passed from person to person.

5.Card 5 : That explosion was the result of damage done to Columbia during its launch. A piece of lightweight protective material fell off the shuttle’s external fuel container. The object hit the shuttle at a high rate of speed and made a hole in one of the wings. This permitted extremely hot gases to enter the shuttle and destroy the spacecraft as it returned to the earth.

 

Very old people do raise moral problems for almost everyone who comes in contact with them. Their values—this can't be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms (蠕虫), and an old person lying alone in bed, taking no notice of the worms. But is it interfering (妨碍) with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old.

Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results. And at what point should you stop treating the old body? Is it morally right to try to push off death by pursuing the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You cannot ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there's life, there's hope.

When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun.
