disastrous to the troubling. One such experiment took place in South America about fifty years ago.
Whether its final consequences will cause serious damage or nothing more than a small trouble still remains
to be seen.
The story began in 1956 when an American scientist working in Brazil decided to solve the problem of
increasing the productivity of that country"s bees. He imported a very active type of African bee from
Tanzania and mated (交配) it with the more easy-going native variety to produce a new kind of bees. The
new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was
the scientist"s name, had a total success on his hands.
Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something
in their environment, the new bees began to develop extremely attacking personalities. They became
bad-tempered and easy to be angry, attacked the native bees and drove them from their living places.
But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings
(叮), began to attack its neighbours-cats, dogs, horses, chickens and finally man himself. A long period of
terror began that has so far killed a great number of animals and about 150 human beings.
This would have been bad enough if the bees had stayed in Brazil. But now they are on the move,
heading northwards in countless millions towards Central and North America, and moving at the alarming
speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if
nothing can be done to stop them.
B. have proved to be wrong
C. are not yet certain
D. are not important
B. make Brazilian bees more easy-going
C. increase the number of bees in Brazil
D. make African bees less active
B. Their hard work.
C. Their living environment.
D. Their bad temper.
B. the bees may bring about trouble in more countries
C. the bees must be stopped from moving north
D. the bees prefer to live in Brazil

with him, though you"re not tired.
This phenomenon confused scientists for years until a recent study found that people tend to sympathize
with fellow humans. Supporting this claim was the discovery that those children who were unable to form
normal emotional ties with others did not experience contagions (有感染力的) yawning, which showed that
humans communicate regularly without words.
Hogo Critchley, a neuroscientist, has conducted an experiment recently, which will prove that happiness
and sadness can spread like the common cold. According to Critchley, our mind and body are in constant
exchange about how we"re feeling. "Emotions are closely linked with states of internal (内部的) responses,"
he explained. "There are also more visible changes in our gesture and facial expressions. When we"re in a
group, these signals can spread to another person. For example, there"re the obvious tendency to smile when
smiled at and there are less obvious changes that reflect emotions of surprise, anger or sadness such as a
change in our heart rate and blood pressure."
Hugo Critchley further explained, "Our bodies synchronise and when we like the other Person, we even
copy his behaviour. Next time you chat with a friend, take note of how you"re sitting-it"s pretty likely that
you will be the same. Scientists believe it"s our way of telling each other that you"re parents. Through body
language, humans give each other very subtle (微妙的) but clear signals that show emotions."
So, what lessons can we learn from this? "spend time with happy people-otherwise your health could
suffer," said Critchley. "When we"re sad, our body goes into fight or flight mode. But when we"re happy, our
body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and
it affects everyone around us."
B. we yawn more frequently when we have a cold
C. emotions are connected with states of internal responses
D. the change of blood pressure is not linked with the change of emotions
B. change rapidly
C. relax temporarily
D. respond accordingly
B. anger is less contagious than friendliness
C. surprise is more contagious than smile
D. surprise is the most contagious among emotions
B. Children like copying the actions of the fellow humans.
C. Scientists are still confused about contagious yawning.
D. People tend to communicate more with body language.
leading teachers told The Observer that rising numbers of foreign pupils are putting some of schools near the
breaking point.
Members of the National Association of Head Teachers will this week tell the government that the problem
is starting to change the culture of some schools. Some heads said the situation was out of control.
Though head teachers think the new pupils have great ability and they should be welcomed into schools,
they are worried that they don"t have enough money to deal with the situation.
"There is a feeling among some of our members that this is out of control and no one knows the final
solution," said Mick Brookes, general secretary of the NAHT. Brookes who will give evidence this week to
the government added,"some schools just don"t know how many immigrant children they will have to admit."
He said that while schools could take in one or two foreign pupils, some were struggling with the sudden large
increase in the number of children overseas.
Clarissa Williams, head of Tolworth Girls School in Kingston upon Thames, south London, said she
received &1,300 a year from the government to cover the costs of teaching English to foreign pupils but was
having to spend &30,000 of her own budget to keep pace.
On Tuesday, the association will tell the House of Lords that education budgets have not kept pace with
the increase in the number of pupils for whom English is a second language, or not spoken at all, who have
entered Britain since the European Union expanded (扩大)

| Less TV Reduce Kids Weight PALO AITO, California-" Switching off the television may help prevent children from getting fatter-even if they do not change their diet or increase the amount they exercise," US researchers said last week. A study of 192 third and fourth grades, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds (0.91 kg ) less over a one-year period than those who did not change their television diet. "The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician (儿科专家) at Stanford University. " American children spend an average of more than four hours per day watching television and videos or playing games, and rates of childhood being very fat have doubt over the past 20 years," Robinson said. In the study, presented this week to the Pediatric Academic Societies" annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third. Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continue their normal television viewing, even though neither group ate a special diet nor took part in any extra exercise. "One explanation for the weight loss could be the children unstuck to the television may simply have been moving around and burning off calories," Robinson said. "Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson added. |

| Net Library is a library that lends out digital (数字化的) books. It treats a digital book like a paperback copy. It charges libraries per book per copy and gives publishers a cut of the total income. From the consumer"s (消费者) point of view, this means that if more than, say, five people want the latest Danielle Steel romance novel, other people who request that book will get a message saying the title is unavailable. It"s a model many publishers seem to have embraced. More than 350 gave the company rights to hand out their digital works, and McGraw-Hill Corporation and Houghton Mifflin Corporation have put money in the company. The California public libraries and about 1, 800 others across the US are trying out the Net Library service. Some librarians criticize the New Library model. Stanford University librarian Michael Keller argues that the company is creating an unnatural fear of digital works, which is contrary to the ideas of the Internet. Keller and some other librarians argue for the e-book vision set forth by EBrary. EBrary is starting a service that lets us users read books for free. But it will charge about 25 cents a page when a person tries to print out material or copy and paste it into a different file or tries to download a copy onto a computer. Christopher Warnock, chief executive of EBrary, believes most consumers won"t want to buy entire books, only the parts that interest them. "There"s not really a lot of good in owning an electronic file and having to store it and manage it. It doesn"t make sense," he said. |
| 1. How do publishers get money from the Net Library? |
| A. They get money from selling their books to the Net Library. B. They share the money with the Net Library. C. They get money by cutting the cost of the books. D. They get the money from the readers. |
| 2. The underlined word "embraced" in the 3rd paragraph means ______. |
| A. taken something willingly B. held something tightly C. disliked something badly D. tried out something hard |
| 3. From the 2nd paragraph we can see consumers ______. |
| A. don"t care if they are charged money B. enjoy the service of the Net Library C. don"t like other people borrowing books D. complain about the limited number of the new books |
| 4. What does the last paragraph mean? |
| A. Net Library is not a good way for the consumers. B. There is no need for consumers to have a whole book. C. EBrary is not a good library for the consumers. D. It"s reasonable to charge the consumers money for copying some pages. |
