A

For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space,on the chance that someone may be receptive to such messages.

Scientists are using powerful radio telescopes to listen to signals from about 1 000 stars,all within 100 light years of Earth.In addition,they will scan(扫视) the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.

Of the 200 billion stars in the Milky Way galaxy(银河星系), scientists find that five percent are like our sun. Perhaps half of them have a planet like Earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution(进化) of　 life. Based on the inhabitable(that can be lived in) planets in our galaxy,most scientists agree that chances are likely that one or more of these planets support some life.

However, many scientists wonder whether intelligent(有智力的) life exists on other planets.Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.

Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time,some scientists think it is likely that civilization(文明) much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.

2.LONDON(Reuters)-Organic fruit,delivered right　 to the doorstep.That is what Gabriel Gold prefers,and he is willing to pay for it.If this is not possible,the 26-year-old computer technician will spend the extra money at the supermarket to buy organic food.

“Organic produce is always better,”Gold said.“The food is free of pesticides(农药),and you are generally supporting family farms instead of large farms.And more often than not it is locally(本地) grown and seasonal,so it is more tasty.”Gold is one of a growing number of shoppers buying into the organic trend,and supermarkets across Britain are counting on more like him as they grow their organic food business.But how many shoppers really know what they are getting,and why are they willing to pay a higher price for organic produce?Market research shows that Gold and others who buy organic food can generally give clear reason for their preferences-but their knowledge of organic food is far from complete.For example,small amounts of pesticides can be used on organic products.And about three quarters of organic food in Britain is not local but imported(进口) to meet growing demand.“The demand for organic food is increasing by about one third every year,so it is a very fast-growing market,” said Sue Flock,a specialist in this line of business.

Question:What is the meaning of “the organic trend” as the words are used in the text?

A.growing interest in organic food　 　　　　　　　　　　　　 B.better quality of organic food

C.rising market for organic food　 　　　　　　　　　　　　　　　　　 D.higher prices of organic food

1.A child’s birthday party doesn’t have to be a hassle;it can be a basket of fun,according to Beth Anaclerio,an Evaston mother of two,ages 4 and 18 months.

“Having a party at home usually requires a lot of running around on the part of the parents,and often the birthday boy or girl gets lost in wild excitement.But it really doesn’t have to be that way,”said Anaclerio.Last summer,Anaclerio and her friend Jill Carlisle,a Northbrook mother of a 2-year-old,founded a home party-planning business called “A Party in a Basket”.Their goal is to help parents and children share in the fun part of party planning,like choosing the subject or making a cake,while they take care of everything.

Drawing on their experiences as mothers,they have created(制作) 10 ready-to-use,home party packages.Everything a family needs to plan a party,except the cake and ice cream,is delivered to the home in a large basket.

“Our parties are aimed for children 2 to 10,”Anaclerio said,“and they’re very interactive(互动)　 and creative in that they build a sense of drama based on a subject.For example,at the Soda Shoppe party the guests become waiters and waitresses and build wonderful ice cream creations.”

The standard ＄200 package for eight children includes a basket filled with invitation,gifts,games and prizes,paper goods,a party planner and the like.For more information,call Anaclerio at 708-864-6584 or Carlisle at 708-205-9141.

●案例探究

3.One of the greatest killers in the Western world is heart disease. The death rate (率) from the disease has been increasing at an alarming speed for the past thirty years. Today in Britain, for example, about four hundred people a day die of heart disease. Medical experts know that people can reduce their chances of getting heart disease by exercising regularly, by not smoking, by changing their diets, and by paying more attention to reducing stress (压力) in their work.

However, Western health-care systems are still not paying enough attention to the prevention of the disease. There is a need for more programs to educate the public about the causes and prevention of heart disease. Instead of supporting such programs, however, the U. S. health-care system is spending large sums of money on the surgical (外科的) treatment of the disease after it develops. This emphasis (强调) on treatment clearly has something to do with the technological advances that have taken place in the past ten to fifteen years. In this time, modern technology has enabled doctors to develop new surgical techniques. Many operations that were considered impossible or too risky (有风险的) a few years ago are now performed every day in U.S. hospitals. The result has been a huge increase in heart surgery.

Although there is no doubt that heart surgery can help a large number of people, some people point out that the emphasis on the surgical treatment of the disease has three clear disadvantages. First, it attracts interest and money away from the question of prevention. Second, it causes the costs of general hospital care to rise. After hospitals buy the expensive equipment that is necessary for modern heart surgery, they must try to recover the money they have spent. To do this, they raise costs for all their patients, not just those patients whose treatment requires the equipment. The third disadvantage is that doctors are encouraged to perform surgery-even on patients for whom an operation is unnecessary-because the equipment and expert skills are there. A government office recently stated that major heart surgery was often performed even though its chances of success were low. In one type of heart surgery, for example, only 15 percent of patient improved their conditions after the surgery. However, more than 100 000 of these operations are performed in the United States every year.

Question:4.“To do this” (in Paragraph 3) means ________.

A.to help patients recover

B.to increase the number of heart surgeries

C.to get back the money spent on the equipment

D.to buy new equipment for the treatment of heart disease

3.According to the passage, the information “storage failures” refer to ________.

A.the destruction of information collecting system

B.the elimination of one’s total memory

C.the temporary loss of part of one’s memory

D.the separation of one’s action from consciousness

2.Professor Reason recently persuaded 35 people to keep a diary of all their absent-minded actions for two weeks. When he came to analyse their embarrassing errors, he was surprised to find that nearly all of them fell into a few groups.

One of the women, for instance, on leaving her house for work one morning threw her pet dog cer ear-rings and tried to fix a dog biscuit on her car. “The explanation for this is that the brain is like a computer,” explains the professor. “People programme themselves to do certain activities regularly. It was the woman’s custom every morning to throw her dog two biscuits and then put on her ear-rings. But somehow the action got reversed(颠倒) in the programme.” About one in twenty of the incidents the volunteers reported were these“Programme assembly failure.”

Twenty per cent of all errors were “test failures”-primarily due to not verifying the progress of what a body was doing. A man about to get his car out of the garage passed through the back yard where his garden jacket and boots were kept, put them on-much to his surprise. A woman victim reported: “I got into the bath with my socks on.”

The commonest problem was information “storage failures”. People forgot the names of people whose faces they knew, went into a room and forgot why they were there, mislaid something, or smoked a cigarette without realizing it.

The research so far suggests that while the “central processor” of the brain is liberated from second-to-second control of a well-practised routine, it must repeatedly switch back its attention at important decision points to check that the action goes on as intended. Otherwise the activity may be “captured” by another frequently and recently used programme, resulting in embarrassing errors.

Questions:2.The word “verifying” in Paragraph 3 can be replaced by ________.

A.improving 　　　　　　　　　　　　　　　　　　　　　　　　　ging

C.checking 　　　　　　　　　　　　　　　　　　　　　　　　　　 D.stopping
