According to a famous optical(光學(xué)) expert, Alexander, who recently visited Shanghai, the developed countries in Europe and America have made rules that children must wear resinous(樹脂) glasses instead of the traditional glasses made of glass. This is because the glass glasses are more likely to do harm to children’s eyesight.
Alexander pointed out: wearing the right glasses as soon as possible is still the best way to cure and put right children’s eyesight problems.
In America and Japan the resinous glasses have taken up 80 percent of the glasses market. And some European countries and America have made it a law that children, teenagers and drivers must wear resinous glasses. Now, about 10 million children in China have different eyesight problems and they need timely treatment.
But still, too many parents are buying the traditional glass glasses for their children. This is mainly because many parents know little or nothing about the good points of the resinous glasses. Besides, the price for the new glasses is a little higher than the traditional ones.
小題1:This news article mainly wants to tell us _______.

A．Alexander visited China and introduced a new type of glasses

B．we should wear resinous glasses instead of glass glasses

C．resinous glasses are popular in Europe and America

D．glasses can be made of other materials instead of glass

小題2:According to Alexander, the “timely treatment” to eyesight problems is _______.

A．to stop wearing glass glasses any more

B．to buy a pair of glasses and wear them right away

C．to wear suitable resinous glasses at the right time

D．to buy glasses made in Europe, Japan or America if possible

小題3: It can be inferred from this news text that _______.

A．resinous glasses are not on sale in China yet

B．resinous glasses are not acceptable in China

C．glass glasses have disappeared on western market because there is a law against them

D．glass glasses are the first choice in China not only because of their price

A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce (確保) bedtime. Instead, it may be that biologically these sleepyhead students aren’t used to the early hour.
“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent  (青春期的) sleep at Brown’s School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level. she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns.
Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at nigh and sleep later in the morning. But it’s not just a matter of choice –their bodies are going through a change of sleep patters.
All of this makes the transfer from middle school to high school—which may start one hour earlier in the morning  ---- all the more difficult , Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescent are up against difficulties when it conics to trying to be up by 5 or 6 a.m. for a 7:30 a.m. first hell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”
小題1:Carskadon suggests that high schools should not start classes so early in the morning because ________.

A．it is really tough for parents to enforce bedtime

B．it is biologically difficult for students to rise early

C．students work so late at night that they can’t get up early

D．students are so lazy that they don’t like to go to school early

小題2:The underlined phrase “nod off” most probably means “ _______”.

A．turn around

B．a(chǎn)gree with others

C．fall asleep

D．refuse to work

小題3:What might be a reason for the hard transfer from middle school to high school?

A．Adolescents depend more on their parents.

B．Adolescents have to choose their sleep patterns.

C．Adolescents sleep better than they did at childhood.

D．Adolescents need more sleep than they used to.

小題4:What is the test mainly about?

A．Adolescent heath care.	B．Problems in adolescent learning.
C．Adolescent sleep difficulties.	D．Changes in adolescent sleep needs and patterns.

Zinc(鋅) is one of about 20 elements necessary for good health. It is present in the body in a very small amount but makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work.
Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys formerly with the United States Air Force noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate(硫酸鹽) recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate.
The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein(蛋白質(zhì)) foods such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these food. Food markets should add these elements so that more people could get needed amount of these necessary matters.
小題1:Which of the following statements is true?

A．Scientists found how zinc works a long time ago.

B．People need a large amount of zinc to be healthy.

C．Zinc allows important chemical actions to take place in cells.

D．Zinc must be used in the course of medical operation.

小題2: One of the results from the study of zinc is that _______.

A．there’s only a little zinc in the human body

B．food rich in protein contains more zinc

C．some physical problems are caused by lack of zinc

D．a(chǎn)ny patient who receives zinc sulphate gets well immediately

小題3:The best title for the passage may be _______.

A．A New Discovery	B．Zinc and Health
C．How Zinc Works	D．Add Zinc to Your Food

The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.?
During the First World War soldiers who spent long periods in the trenches(戰(zhàn)壕), cold and wet, showed no increased tendency to catch colds.?
In the Second World War prisoners at the notorious Auschwitz concentration camp(奧斯維辛集中營(yíng)), naked and starving, were astonished to find that they seldom had colds.?
At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.?
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains—taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.?
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is to relieve the symptoms(癥狀).?
小題1:The writer offered _______ examples to support his argument.?

A．4

B．5

C．6

D．3

小題2:Which of the following does not agree with the chosen passage??

小題3:Arctic explorers may catch colds when ________.

A．they are working in the isolated Arctic regions?

B．they are writing reports in terribly cold weather?

C．they are free from work in the isolated Arctic regions?

D．they are coming into touch again with the outside world

小題4:The passage mainly discusses ________.

A．the experiments on the common cold

Space travel is definitely bad for astronauts’ bones, reducing their bone density(密度) after only a month of weightlessness, according to French research published on Friday.
Laurence Vico and his fellow workers at St Etienne University called for more research into the effects of microgravity, after their study of 15 astronauts from the Russian MIR station showed bone loss continued throughout space flights.
“Bone loss was especially striking in four astronauts, ” the scientists reported in the Lancet Medical Journal.
They measured the bone mineral density (BMD) of bones in the forearm(前臂) and lower leg of the astronauts who had spent one to six months in space.
The BMD loss was significant in the tibia(脛骨) of the lower leg, a weight-bearing bone, but barely changed in the radius(橈骨) of the forearm. “Our results indicate the need to investigate not only different bones, but also different areas of the same bone since not all sites of the skeleton (骨架) are similarly affected by space conditions, ” they added.
Without gravity the body isn’t bearing any weight so there is no need for calcium (鈣) which makes bones strong, and it becomes empty into the bloodstream.
The research team suggested in future scientists should try to determine if the loss of bone density was only on weight-bearing bones on longer flights, also the possible recovery after returning to Earth.
小題1:French scientists did their research on Russian astronauts, because _______.

A．they only cared for the Russian astronauts

B．they were not interested in their own astronauts

C．the Russian government invited them to do their research

D．the Russian astronauts worked in space for a long time

小題2:Scientists have found that _______.

A．the BMD loss may cause serious illness to astronauts

B．the BMD loss may cause some change in astronauts’ bodies

C．a(chǎn)stronauts shouldn’t care about the BMD loss

D．a(chǎn)stronauts should take some calcium before space travel

小題3:What cause the BMD loss to astronauts, according to this passage?

A．The food they eat in space.	B．The drinks they take in space.
C．The temperature in space.	D．The gravity in space.

小題4:In the third paragraph, the word “striking” means ______.

A．unusual

B．simple

C．weak

D．slow

Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient —no matter where he or she may be.
Online doctors offering advice based on normal symptoms(癥狀) are the most obvious example. Increasingly, however, remote diagnosis(遠(yuǎn)程診斷) will be based on real physiological data(生理數(shù)據(jù)) from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone, it is perfectly practical to send a patient’s important signs over the telephone. With this kind of equipment, the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural(countryside) care. And at least one team wants to use telemedicine as a tool for disaster need—especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts’ opinions.
But there is one problem. Bandwidth(寬帶) is the limiting factor for sending complex(復(fù)雜的) medical pictures around the world — CT photos being one of the biggest bandwidth users. Communication satellites may be able to deal with the short-term needs during disasters such as earthquakes or wars. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts’ opinions and diagnosis are common.
小題1: The writer chiefly talks about _______.

A．the use of telemedicine	B．the on-lined doctors
C．medical care and treatment	D．communication improvement

小題2:The basis of remote diagnosis will be _______.

A．personal data assistance

B．some words of a patient

C．real physiological information

D．medical pictures from the Internet

小題3:Which of the following statements is true according to the text？

A．Patients don’t need doctors in hospitals any more.

B．It is impossible to send a patient’s signs over the telephone.

C．Many teams use telemedicine dealing with disasters now.

D．Broadband communications will become cheaper in the future.

小題4:The “problem” in the fourth paragraph refers to the fact that _______.

A．bandwidth isn’t big enough to send complex medical pictures

B．the second-generation of Internet has not become popular yet

C．communication satellites can only deal with short-term needs

D．there is not enough equipment for spreading the medical care

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increase the risk.
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (發(fā)生率) faster than any other cancer in the United States.
But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
小題1:72. The underlined word “flaws” in the 2nd paragraph most probably means ______.

A．evidence

B．facts

C．faults

D．failures

小題2:73. People with fair skin and freckles          .

A．seldom use sunscreen	B．a(chǎn)re more in danger of skin cancer
C．can be free from the harm of the sun	D．often expose themselves to the sun

小題3:74. We can learn from the passage that ______.

A．sunscreen users get skin cancer more often

B．the volunteers have proved the effect of sunscreen

C．the new study was based on the experiences of volunteers

D．the number of skin cancer patients is increasing in America

小題4:75. Which of the following can be the title for this passage?

A．Sunscreen to Prevent Skin Cancer	B．Sunscreen to Increase Skin Cancer
C．Skin Cancer Caused by Sunscreen	D．Skin Cancer Caused by Freckles

D
Seeing a volcano erupt (噴發(fā)) is a wonderful experience, and you can really feel the beat by climbing to the summit(山頂) of Pacaya for a close-up view. There are guided tours every day up this highly active volcano from Antigua. Giving travelers a chance to see Mother Nature at her most powerful.
Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won’t miss the Pacaya-tour companies.
But climbing Pacaya is no easy job: it is 2560 metres high, and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb, you hear the dull sounds of eruptions high above. Steaming. Hot remains from recent eruptions begin to line the path as you near the active summit; the McKenney Cone(火山錐). Just as though you were going to walk over to the edge of the cone, the road turns to the left and up to the relative safety of the old, inactive summit.
Many tours are timed so that you arrive at the cone of the volcano is plenty of time for sunset and the full contrast between the erupting red lava(熔巖) and the darkening sky. On a good day the view from the summit is extremely exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot streams up to 100 metres into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night. the burning lava quietly falls down tae side of the volcano. For you, too, it is time to get down .
小題1: What is the main purpose of this passage?

  Centuries ago, man discovered that removing moisture from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind.
All foods including water — cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean (瘦的) meat 75% and fish, anything from 80% to 60%, depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is controlled.
Nowadays most foods are dried mechanically. The conventional method of such dehydration (脫水) is to put food in chambers (室) through which hot air is blown at temperature of about ll0'C at entry to about 43'C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.
Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated steel cylinder (圓筒), then put them into a chamber through which a current of hot air passes. In the first process, the dried material comes off the roller (滾筒) as a thin film which is then broken up into small, though still relatively flakes (薄片). In the second process it falls to the bottom of the chamber as small powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients (成分) are dried separately and then mixed.
Dried foods take up less room and weigh less than the same food packed in cans or
frozen, and they do not need to be stored in special conditions. For these reasons they
are invaluable to the climbers, explorers and soldiers in battle, who have little storage
space. They are also popular with housewives because it takes so little time to cook
them.
小題1:It can be inferred from the passage that ________.

A．the rattier fish contain as much water as the lean one

B．the rattier the fish is, the more water it may contain

C．a(chǎn) fatty fish holds less water than a lean one

D．the water content of fish has nothing to do with the content of their fat

小題2: The underlined word "conventional" in Paragraph 3 can most probably be replaced by _________.

A．particular

B．scientific

C．usual

D．special

小題3:Which of the following statements is NOT true about drying food?

A．The removal of water in food helps prevent it from going rotten.

B．The open-air method of drying food has been known for hundreds of years.

C．In the course of dehydration, the temperature of hot current coming from entry to exit is gradually going up.

D．The process of drying liquids is much more complex than that of drying solid food.

小題4:The last paragraph mainly talks about __________.

A．the reason why housewives like dried food

B．the general convenience of dried food

C．the methods of storing food

D．the advantages of dried, canned and frozen food

Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(壽命) can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary(遺傳的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.    
小題1:What does "these two killers" in the second paragraph refer to? 

A．gene technology and another treatment of the two diseases.

B．The two murderers who killed the cloned baby

C．The two diseases of cancer and heart disease

D．Hereditary diseases and cancer

小題2: What's the main idea of the third paragraph?

A．How gene technology can be applied in the field of treating hereditary diseases.

B．Gene technology can be used to clone human babies.

C．Gene technology can help people to give birth of a baby.

D．Gene technology can help the English imperial family out

小題3:In what way gene technology can help to treat hereditary diseases?

A．Using gene technology, people with hereditary diseases can have more living days.

B．Using gene technology, scientist finds the wrong gene and corrects it.

C．Using gene technology, human babies can be cloned.

D．Doctors can cure cancer and heart disease with the help of gene technology.

小題4:What is the main purpose of writing this passage?

A．Expressing the writer's idea that gene technology will benefit people

B．Telling people the advantages of gene technology

C．Telling the readers that gene technology will not benefit people

D．Explaining that gene technology will also do harm to the humanity
