People should be warned against using mobile phones outdoors in stormy weather because they may “be struck by lightning”, according to doctors.
Three experts have described how a teenage girl was struck by lightning while using her phone in a large London park. The girl, aged 15, recovered, but a year later was still wheelchair-bound and found to be suffering complex physical and emotional problems.
The girl also had a perforate eardrum(打孔耳膜)on the side where she had been holding the mobile phone. She was having general recovery in Northwick Park Hospital, Middlesex.
Swinda Esprit, a senior house offi­cer, said that while the brain and muscle damage was similar to that of many lightning victims—who can experience heart attacks on being struck— the ear problems were not.
She said that the damages were particularly relevant for people who might be involved in less seri­ous lightning incidents, who might other­wise recover, but would never get their full hearing back if struck while on the phone.
“We were shocked by the damage, which is why we wanted to draw attention to it,” Dr Esprit said. “A year on and she still was suffering these difficult hearing.”
They added that three other cases had been reported in newspapers in China, South Korea, and Malaysia. In the Malaysian case, a sales executive was killed by lightning while talking on his phone during a thun­derstorm near Kuala Lumpur.
“All these events resulted in death,” the doctors wrote. “This rare phe­nomenon is a public health issue, and edu­cation is necessary to stress the risk.”
The Australian Lightning Protection Standard recommends that metallic objects, including cordless or mobile phones, should not be carried out­doors during thunderstorms. However, “the United States National Weather Service says on its website that both are safe to use “because there is no direct path between you and the lightening”.
Paul Taylor, of “the Met Office”, said the ear injuries were a consequence of mobile phones being metal, and not related to radio waves.
Mr. Taylor said that mobile phones should be treated as another piece of metal, similar to carrying coins or wearing rings, and people need to be warned against the possi­ble danger.
51. What do we know about the teenage girl?
A. She was struck by lightning at school.
B. She completely recovered from being struck.
C. She still suffered from mental problems.
D. She had to press her ear all day.
52. It can be inferred that damage done by lightening while using mobile phones ______.
A. is more serious than that when one is not using a mobile phone                         
B. can be healed quickly except for heart attacks
C. is less serious because the victims can usually recover                   
D. is mainly in the brain and muscle of the victims
53. Why did doctors stress the risk about using phones outside in lightening?
A. Because more people are faced with it.     B. Because some deaths have been caused.
C. Because lightning is harmful for the brain.   D. Because a teenage girl got killed.
54. We can infer from the last three paragraphs that ______.
A. both cordless and mobile phones are safe to use outside in lightning
B. there is no direct connection between lightning and ear injuries at all
C. opinions differ as to whether it is safe to use mobiles phones in lightning
D. ear injuries are the result of carrying coins or wearing rings in lightning
55. The purpose in writing this passage is ______.
A. to draw attention to the risk of using mobile phones in lightening
B. to focus on various damages done to lightning victims
C. to tell us the news that a teenage girl was struck by lightning
D. to stress the danger of making phone calls in lightning

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling.Recycling in the home is very important of course.However, being forced to recycle often means we already have more material than we need.We are dealing with the results of that over–consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging has increased by 12% between 1999 and 2005.It now makes up a third of a typical household’s waste in the UK.In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment.The UK, for example, is running out of it for burying this unnecessary waste.If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect.Recycling helps, but the process itself uses energy.The solution is not to produce such items in the first place.Food waste is a serious problem, too.Too many supermarkets encourage customers to buy more than they need.However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets.It is about all of us.We have learned to associate packaging with quality.We have learned to think that something unpackaged is of poor quality.This is especially true of food.But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope.As more of us recycle, we are beginning to realize just how much unnecessary materials are collected.We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
小題1:What does the underlined phrase “that over-consumption” refer to?
A.Using too much packaging.
B.Recycling too many wastes.
C.Making more products than necessary.
D.Having more material than is needed.
小題2:The author uses figures in Paragraph 2 to show ___________.
A.the tendency of cutting household waste
B.the increase of packaging recycling
C.the rapid growth of supermarkets
D.the fact of packaging overuse
小題3:According to the text, recycling ___________.
A.helps control the greenhouse effect
B.means burning packaging for energy
C.is the solution to gas shortage
D.leads to a waste of land
小題4:What can be inferred from Paragraph 4?
A.Unpackaged products are of bad quality.
B.Supermarkets care more about packaging.
C.It is improper to judge quality by packaging.
D.Other products are better packaged than food.

“A good book for children should simply be a good book in its own right,”says Mollie Hunter. Born and brought up near Edinburgh, Mollie has devoted her talents to writing primarily for young people. She firmly believes that there is and should always be a wider audience for any good book whatever its main market is. In Mollie’s opinion it is necessary to make full use of language and she enjoys telling a story, which is what every writer should be doing, “If you aren’t telling a story, you’re a very dead writer indeed.”she says. With the chief function of a writer being to entertain, Mollie is indeed an entertainer. “I have this great love of not only the meaning of language but of the music of language,”she says. “This love goes back to early childhood. I’ve told stories all my life. I had a school teacher who used to ask us what we would like to be when we grew up and, because my family always had dogs, and I was very good at handling them. I said I wanted to work with dogs, and the teacher always said‘Nonsense, Mollie; dear, you’ll be a writer.’So finally I thought that this woman must have something, since she was a good teacher and I decided when I was nine that I would be a writer.”
This childhood intention is described in her novel, A Sound of Chariots, which although written in the third person is clearly autobiographical (自傳體的)and gives a picture both of Mollie’s ambition and her struggle towards its achievement. Thoughts of her childhood inevitably(不可避免的)brought thoughts of the time when her home was still a village with buttercup meadows and strawberry fields-sadly now covered with modern houses. “I was once taken back to see it and I felt that somebody had lain dirty hands all over my childhood. I’ll never go back,”she said.“Never.”“When I set one of my books in Scotland,”she said,“I can recall my romantic feelings as a child playing in those fields, or watching the village blacksmith at work. And that’s important, because children now know so much so early that romance can’t exist for them, as it did for us.”
小題1: What does Mollie Hunter feel about the nature of a good book?
A.It should not aim at a narrow audience.
B.It should be attractive to young readers.
C.It should be based on original ideas.
D.It should not include too much conversation.
小題2: In Mollie Hunter’s opinion, which of the following is one sign of poor writer?
A.Being poor in life experience
B.Being short of writing skill.
C.The weakness of description
D.The absence of a story.
小題3:What do we learn about Mollie Hunter as a young child?
A.She didn’t expect to become a writer.
B.She didn’t enjoy writing stories.
C.She didn’t have any particular ambition.
D.She didn’t respect her teacher’s view.
小題4:In comparison with children of earlier years, Mollie feels that children now are _____.
A.more intelligent
B.better informed
C.less eager to learn
D.less interested in reality
小題5: What’s the writer’s purpose in this text?
A.To share her enjoyment of Mollie Hunter’s book.
B.To introduce Mollie Hunter’s work to a wider audience.
C.To provide information for Mollie Hunter’s existing readers.
D.To describe Mollie Hunter’s most successful books.

Honeybees are disappearing for unknown reasons around the United States.Last winter, bees disappeared from 23 percent of American beekeeping businesses.Causes of the phenomenon, however, have remained a mystery.
Now, scientists from several universities and the United States Department of Agriculture say they have a possible explanation for the bee decline(數(shù)量下降).It is a little known virus called Israeli acute--paralysis virus (IAPV).The virus kills bees.Researchers in Israel first described it in 2004 , but until now, bee experts hadn’t paid much attention to it.
When trying to find out why the bees were disappearing, a research team at Columbia University studied bee colonies (群體), some with and the others without decline.The research turned up large numbers of two types of fungi (真菌) once suspected of causing the bee decline.The research results, however, showed that the fungi were almost as common in colonies without a decline as they were in colonies with a decline.The researchers concluded that the two fungi probably weren’t the cause.
Studies of the presence of IAPV, however, showed more interesting information.In those studies, done by a team at Pennsylvania State University in University Park, the virus showed up in 83 percent of samples from colonies with symptoms (癥狀).Only five percent of samples from symptomless colonies had it.
Scientists still don’t know whether IAPIV can single--handedly cause the bee decline.They believe that even if the virus is making colonies sick , it could have a partner in crimeIt’s possible, for instance, that insects or chemicals in the environment weaken bees, making them more likely to catch IAPV.
Scientists are still trying to figure out how IAPV came to the United States.The United States currently allows bee products to be imported from Canada, Australia, and New Zealand.If it turns out that this trade is spreading disease, the rules might eventually change.
小題1:According to the passage ,IAPV is a virus that ______.
A.hasn’t attracted much attention
B.well-known to doctors and scientist
C.was first found by Austrian researchers
D.is dangerous to animals and human beings
小題2:The underlined sentence in the fifth paragraph probably means______.
A.the virus could also cause other damages
B.there must be something that is the real cause
C.IAPV is not the only cause for the bee decline
D.the virus may be caused by the polluted environment
小題3:From the third and fourth paragraphs, we know researchers draw their conclusions by means of _______.
A.calculating B.comparingC.examiningD.investigating
小題4:What still remains unknown to American scientists according to the passage?
A.How and why to kill IAPV.
B.How IAPV came to America.
C.Whether bee products should be imported.
D.How to change the rules of the bee products trade.
小題5:The best title for this passage would be _____.
A.Bee DiseaseB.How to Kill IAPV
C.A Virus—IAPVD.Two Types of Fungi

Under normal conditions the act of communication requires the presence of at least two persons: one who sends and one who receives the communication. In order to communicate thoughts and feelings, there must be a conventional system of signs of symbols which mean the same to the sender and the receiver.
The means of sending communications are too numberous and varied for systematic classification, therefore, the analysis must begin with the means of receiving communication. Reception of communicatio isachievedbyourenses.Sight,hearing,andtouch play the most important roles. Smell and taste paly very limited roles, for they cannot receive intellectual expression from fully developed systems of signs and symbols        
Examples of visual communication are gesture and mimicry (模仿). Although both frequently ac- company speech, there are systems that rely solely on sight, such as those used by deaf and dumb per- sons. Another means of communication visually is by signals of fire, smoke, flags and flashing lights. Feelings may be simply communicated by touch, such as by handshaking or backslapping, although a highly developed system of handstriking has enabled blind, deaf, and dumb persons to communicate intelligently. Whistling to someone, applauding in a theater, and other forms of communication by sound rely upon the ear as a receiver. The most fully developed form of auditory communication is, of course, the spoken language.
The means of communication mentioned so far have two features in common: they last only a short time and the persons involved must be relatively close to each other. Therefore, all are restricted in time and space.
64. The author explains he will deal with reception of communication first because   
A. communication actually takes place when the message is received
B. there are more means of receiving than of sending cmmunication
C.reception of communications involves use of the senses
D.it is difficult to organize by type the means of sending communication
65. Persons who cannot see, hear, or speak are able to communicate through a system of
A. gesturing       B. handshaking      C. backslapping       D. handstriking
66. A form of visual communication often used with a type of auditory communicati      
A. gesturing     B. handshaking        C. backslapping       D. handstriking
67. The author specifically mentions that speech is
A. often used when communication by touch
B. necessary for satisfactory communication by gesture
C. the only highly developed system of communication
D.the most developed form of communication based on hearing
68.Which of the following statements about communication by touch is true?
A. Touch is less important than taste as a means of communication.
B. There is no well-developed system of communication based on touch.
C. It is possible to communicate intelligently by touch alone.
D. Touch must accompany visual communication.

Some fish form huge schools. Could fish set up schools and teach their children how to survive in the ocean? You may ask. No. Here the “schools” are not the places where you study. They are fish shoals (魚群) that cover tens of kilometers. What causes hundreds of millions of fish to gather and move together is one of biology’s mysteries.
Darkness appears to be the first step to the creation of shoals, according to a study published in the March 27 journal Science. A team of researchers from the Massachusetts Institute of Technology (MIT) and five other institutions studied Atlantic herring (鯡魚), which forms shoals on a fishing ground off Massachusetts. They used an underwater imaging technology and fish-finding sonar (聲納) to observe the herring over several days in autumn when they spawn (產(chǎn)卵).
They found that, as the sun set, fish in scattered (分散的) groups began swimming much closer to one another than they normally do. When the number of fish reached a certain point in an area, this set off a chain reaction of similar behavior that spread like a sound wave through the water.
The herring’s movement seemed to be started by sunset. The team didn’t record the breakup of these shoals, but a previous study suggested that as the sun rose, the shoals fell apart.
“When the light fades (逐漸消失), it’s safer for the fish to move away from the seabed,” says Nicholas Makris, a professor at MIT who led the research. “Once they have a certain number of other fish, they suddenly come together - forming a shoal covering tens of kilometers within tens of minutes.”
Herring form shoals to migrate during the autumn spawning season. Some shoals were 40 km across and 30 m from top to bottom. They formed in deep water and moved into more shallow waters to spawn.
Forming shoals helps protect them from predators (掠食者) by giving them simple strength in numbers. The ordered movement of the shoal means the fish can reach their spawning ground more quickly and more safely.
Scientists have never before gathered information on so many animals acting together. Understanding these herring shoals could lead to more ideas about what causes animals to move in schools, says Iain Couzin, a biologist at Princeton University, US.
1. Which school in the following expressions is used the same way as the underlined one in the first paragraph?
A. schools of thoughts       B. school a horse   C. a school of whales       D. a medical school
2. Which of the following statements is true?
A. There are more large shoals of herring at night than in the daytime.
B. The research on Atlantic herring was conducted independently by the Massachusetts Institute of Technology.
C. The larger the shoal of herring is, the more slowly it moves.
D. Scientists have found out the reason why fish gather and move together in huge shoals.
3. According to the research, herring tend to get together except ______.
A.when there are predators around  B. when they spawn C. when the sun sets  D. when the sun rises
4. What seems to be the main reason for herring to gather and move together?
A. To avoid the darkness.
B. To keep other kinds of fish out of their spawning ground.
C. To spawn in the shallow waters.
D. To make themselves feel safe.

Because plants cannot move or talk, it is believed that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true.
People who studied plants have found out that plants carry a small electrical charge (電荷). It is possible to measure this charge with a small piece of equipment called “galvanometer”. The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.
A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them - perhaps by pulling off its leaves or by pulling it out of its pot - then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects (昆蟲).
Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.
Another scientist, named Sauvin, achieved similar results to Backster’s. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.
60. Why was Backster surprised at the results of his studies?
A. Because he found someone had just cut down a tree.
B. Because he destroyed a plant by pulling it out of its pot.
C. Because he found that plants could move and speak after all.
D. Because he found that plants could express feelings of shock.
61. The plants sent out signals _____.
A. only when Backster Started to destroy plants
B. when Backster destroyed plants or other living things
C. only when he destroyed things such as insects
D. only when Backster placed the galvanometer on the leaves of the plants
62. The scientist called Sauvin _____.
A. did not agree with Backster’s ideas
B. did not get the same sort of results as Backster did
C. found out some of the same things that Backster did
D. got different results from Backster’s
63. Which of the following is true according to the passage?
A. The electrical charge plants carry may shock or frighten us.
B. A tree will signal when it has been cut down.
C. Sauvin could make his plants send out signals some distance away.
D. Plants have feelings because they can receive signals without moving.
