A Concussion（脑震荡） happens when the brain is shaken, often in a car crash or a fall or a strike on; the head in sports．Concussions can be mild, but doctors may order a CT scan to look for a more serious injury．But a recent study warned that more children than necessary are being exposed（使遭受） to radiation this way．
A national team led by two doctors at the University of California, Davis, studied hospital records from thousands of children with head injuries. They found that in many cases, the risk of developing cancer from the radiation outweighed the risk of a serious brain injury.
The study found that one in five children over age two had a low risk of serious injury but received CT scans anyway. The same was true of almost one in four children under two years of age.
The researchers have developed rules to predict if a head injury is serious enough for a scan. For children under two, doctors are advised against it if there is:
·Normal mental activity.
·No swelling in the back of the head.
·No feeling of a broken bone in the skull. (头骨)
·And no loss of consciousness for more than five seconds.
Doctors should also consider how the child was injured and whether the parents say the child is acting normally.
For patients from two to eighteen, the guidelines are similar —— except there should be no l vomiting（呕吐）and no severe headache.
Earlier this year, the British Journal of Sports Medicine published new guidelines for concussions in children and teens. International experts said they should not return to sports or school until fully recovered. The brain also needs a "cognitive rest," they say, by restricting activities like video games, texting and watching TV.
It often take longer than adults to recover from a concussion than adults. The experts say individual progress and not a set time period should always guide a decision to return to play.
小题1:The researchers at the -University of California found that children who received CT scans
A．were likely to suffer brain injuries
B．wouldn’t have normal mental activity
C．would lose consciousness now and then
D．were likely to develop canter
小题2:How many aspects should doctors consider when deciding whether a child under two needs a CT scan?        
A．Four．B．Six．C．Seven．D．Nine．
小题3:What can we learn from the last two paragraphs?
A．Texting is harmful to patients’ recovery from concussions．
B．Patients with brain injuries can play many sports．
C．Adults need a longer time than teens to recover from concussions．
D．It takes at least a year for individuals with brain injuries to fully recover．
小题4:The author of the passage mainly___．
A．describes the risks of brain injuries
B．suggests CT scans are of practical use
C．tells us about the risks of brain injury tests
D．argues against new guidelines for concussions
    Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts.
The American Lung Association (ALA) has issued new guidelines on combating colds and the flu(流感), and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses - flu A, B and C. There is no cure for either illness , but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities , there are some obvious signs to look for.
Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.
The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.
Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome(综合症) ，a rare but serious condition of the liver and central nervous system.
There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.
　
小题1: According to the author, knowing the cause of the misery will help ________.
A．shorten the duration of the illness
B．the patient buy medicine over the counter
C．the patient obtain cheaper prescription drugs
D．prevent people from catching colds and the flu
小题2: We learn from the passage that ___________.
A．one doesn’t need to take any medicine if he has a cold or the flu
B．aspirin should not be included in over-the-counter medicines for the flu
C．delayed treatment of the flu will harm the liver and central nervous system
D．over-the-counter drugs can be taken to ease the misery caused by a cold or the flu
小题3: According to the passage, to combat the flu effectively, ___________.
A．one should identify the virus which causes it
B．one should consult a doctor as soon as possible
C．one should take medicine upon catching the disease
D．one should remain alert when the disease is spreading
小题4:Which of the following symptoms will distinguish the flu from a cold?

A．are advised not to give them aspirin
B．should watch out for signs of Reye syndrome
C．are encouraged to take them to hospital for vaccination
D．should prevent them from mixing with people running a fever
If you want to increase your vocabulary, the best way to do it might be to pick up a guitar, or learn the violin. A new study shows that learning to play a musical instrument makes the brain more able to remember words.
“Grown-ups with music training in their childhood can have better memory for words,” said Dr Agnes Chan of the Chinese University of Hong Kong, who did the research. “They can remember things that you tell them better than those who did not have music training when they were young.”
It seems that one can remember spoken words because his brain has a special part. “That part of the brain is larger in musicians than in non-musicians,” Dr Chan told BBC. “If that part of the brain is larger, it may be better developed and so this explains very nicely our results.”
Dr Chan and her workmates came to their conclusion after studying students. Their research is reported in the latest edition of the journal(杂志) Nature. “We did the experiment with 60 girl college students from our university and 30 of them have at least six years training with one western musical instrument (such as the violin and the piano) before the age of 12. The other 30 had received no music training. We tested their memory by reading them some words and asking them to remember these words—a very common test for memory. We found that people who have had music training can remember about 70% more information than those who have not had any music training.”
Dr Chan thinks the process(过程) of learning is more important than the actual instrument used. She also believes if one is able to remember words through learning to play instruments, he or she could have some very real benefits. Dr Chan thinks this could be developed into a medical way for patients who are suffering from memory loss.
小题1: According to the writer, learning to play a musical instrument helps to ______.
A．get more knowledge
B．live more happily
C．remember more words
D．make one become a musician
小题2:Which of the following is true according to the passage?
A．Dr Chan thinks people should have music training when they grow up.
B．Dr Chan thinks the special part of the brain doesn’t need developing.
C．Dr Chan thinks people should have music training when they are young.
D．Dr Chan thinks musicians have a larger brain than non-musicians.
小题3:How many students took part in Dr Chan’s research?
A．30 girl students.B．60 girl students.
C．17% of his students.D．60 girl and boy students.
Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens（过敏原）,prompting researchers to ask: Are cats and dogs really safe for children？
A study finds that, contrary to many parents' fears, owning cats or dogs does not increase a child's risk of developing allergies, and in fact, may actually protect them. The study's lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was "very surprised" by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
By using skin-prick tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps" exercise" their immune systems early in life so that they're better able to resist allergic diseases later.
There's something very important in that first year of life when the immune system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child's allergy risk, they say if a family already has one or more animals, there's no need to get rid of them.
小题1:Why do the researchers feel “very surprised” by the results of the study?
A．Because the results are contrary to their expectation．
B．Because so many children are playing with cats and dogs．
C．Because parents are so much worried about their children．
D．Because children with animals may develop allergies easily．
小题2:Compared with children who have pets，those who haven’t  ______.
A．will lose the chance to develop immune system
B．may suffer allergic diseases more often
C．will reduce the harm from bacteria
D．can keep doctors away
小题3:It can be inferred from the passage that ______．
A．pets are ill-treated by their owners
B．less families would like to own cats and dogs
C．keeping pets is a good way to keep children healthy
D．the results of the study can make families with pets feel at ease
小题4:The underlined word “it” in the fifth paragraph refers to________.
A．the early life
B．an allergic disease
C．immune system
D．something important
小题5:What may be the best title of the passage?
A．How to protect your kids from allergies
B．Your pets may be helping your kids
C．Bacteria do good to your kids
D．Advantages of owning pets
Football is so popular in China. Almost everyone is interested in the sport — young and old, boys and girls, and now even robots.
Last week at Hangzhou Guangming Middle School, kids from several schools played football with their robots.
Robot football was very different from human football. Only two robots played in each match. The field was as big as a ping-pong table. One half was black and the other was white. Each robot tried to catch the “football” and score a goal. The robot with more goals won.
Gao Linge, a boy from Guangming Middle School, helped make one of the robots for the match.
“My school bought the main board (主板),” said Gao, 14. “Then I decided what my robot looked like and made a computer programme for it.”
Gao’s robot was eight centimeters tall and had two arms. It had four sensors (传感器) to “see” and “kick” the football.
Ying Xuehai, a 12-year-old student from Gao’s school, also made a robot. His robot played against Gao’s. The match decided who would go to the final game. Ying lost the game. So he gave many of his robot’s parts to Gao.
Even so, Gao’s robot didn’t win the final. It played well in the first five minutes. Then it slowed down. By the end of the match, it could hardly move. What was wrong? Gao and Ying found the problem — their robot ran out of batteries (电池)!
“We’ll solve the problem and beat the other school next time!” said the two boys.
小题1: How many robots are needed in one match?
A．Only one.B．Two.C．Three.D．Four.
小题2: The third paragraph mainly talks about ________.
A．a wonderful robot football game.B．how to let robots score more goals
C．the rules of the robot football games.D．the way for robots to win the match
小题3: Why did Gao Linge lose the final?
A．Because his robot had no power.B．Because he broke the rules of the match.
C．Because he used Ying Xuehai’s parts.D．Because his robot went wrong.
小题4: From the passage we know that if you want to take part in the match, ________.
A．you must go to Hangzhou.B．you must know something about computers
C．you must know how to play football on the playground
D．you must get along with Gao Linge and Ying Xuehai
If you have to miss one meal a day, which meal will cause you fewest health problems if you don’t eat it? If they have to make a decision of this type, most people (especially very busy people) will choose to skip (not to eat) breakfast.
However, many experts in the field of health consider breakfast (the meal which “breaks” your “fast---- a period of time without eating anything ” which started the night before) to be the most important meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients we need to begin our working day with vigor and hopefully with good humour. But many people skip breakfast or replace it with snacks or a cup of coffee for a well-balanced meal. What happens if we ignore the importance of breakfast?
One recent study conducted in the United States tested a large number of people. Participants included both males and females who ranged in age from 12—83. During the experiment, these people were given a variety of breakfasts, and sometimes, they had to skip breakfast completely. Special tests, including blood tests and endurance tests, were set up to analyze how well the participants’ bodies functioned when they had eaten a certain kind of breakfast.
The result showed that if a person eats an adequate (充足的) breakfast, he or she will work more efficiently and more productively than if he or she skips breakfasts or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental activity. The study showed that if schoolchildren eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast diet is inadequate .
The study also showed that, contrary to what many people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you are on a diet, skipping breakfast will not help you. You will probably lose more weight if you reduce your other meals.
小题1:According to the passage, we can safely say _____.
A．if you skip breakfast, you will not lose weight at all
B．if you skip breakfast, you won’t eat much for lunch either.
C．skipping breakfast won’t do a bit of harm
D．skipping breakfast will help one lose weight
小题2:In the word “breakfast”, “fast” probably means _____.
A．“moving quickly”B．“going without food ”
C．“unlikely to go fast”D．“fast food ”
小题3:Special tests were organized to analyze how participants’ bodies functioned when ______.
A．they had skipped breakfasts B．they had had breakfasts
C．they had eaten special breakfasts D．they had had all three meals
There is a joke among flu researchers: “If you've seen one flu season, you've seen one flu season.” The joke is about the unpredictable nature of the flu virus. Every year it looks different, and every strain (类型) follows its own pattern — it's the reason why new strains like H1N1 are extremely difficult to predict.
Dr. Michael Osterholm is a former adviser to the U.S. Department of Health and Human Services. “I know less about influenza today than I did 10 years ago,” he says in a joking way. “Every stone we've turned over, we get more questions.”
The flu rectums every season and the world experiences terrible pandemics (全国或全世界范围流行的疾病), but researchers still do not understand why some strains infect people and others do not; they are not entirely sure about how the flu is transmitted; nor do they understand why some patients become seriously ill while others develop mild symptoms (症状). As a result, when a new strain shows up — like H1N1 — they often have little information to fall back on, and the lessons of previous pandemics are only somewhat helpful. While researchers are still putting together a complete picture of H1N1, for example, its most striking difference with the seasonal flu is that the elder1y are not the most vulnerable (易受攻击的) population.
Influenza's unpredictable nature makes it a moving target for researchers, says researcher Allison Aiello at the University of Michigan. “Even if we had complete seasonal flu data from the past, it wouldn't be much helpful for a new strain of influenza,” she explains.
Whi1e researchers are frustrated by the holes in their knowledge, they say, however, that the pub1ic--health community is generally doing a very good job responding to H1N1 with seasonal flu data that do exist. Studying influenza, says Osterholm, is “like looking through the windows of a house you can't get into because the door is locked.” Gathering the data researchers do have is like “looking through the windows to get a pretty good picture of what the inside looks like.”
One thing researchers do know for sure: the best way for people to protect against H1N1 is to get the vaccine once it becomes available to them.
小题1:What do we learn about H1N1 from the passage?
A．In fact it is not a kind of influenza virus.
B．It is quite possible to predict it in theory.
C．Old people are more likely to contract it than kids.
D．Receiving vaccines will be effective to protect against it.
小题2: The underlined phrase “fall back on” in Para. 3 probably means      .
A．rely onB．pass onC．col1ect D．exchange
小题3: What do we know about previous seasonal flu data?
A．It is useless to study them.
B．It is still necessary to study them.
C．They are misleading most of the time.
D．They are much more helpful than expected.
小题4:Which of the following could be the best title for the passage?
A．Outbreaks of the fluB．Symptoms of the flu
C．Mysteries of the fluD．Risks of the flu

It is now commonly known that AIDS is a deadly disease. It does great damage to human beings’ immune system, weakening resistance to disease and leading to death due to utter weakness. To this day, there are no existing drugs that can kill AIDS virus. It is a deadly battle between science and AIDS.
This is only one side of the story. Although it can not be cured, AIDS is preventable. For those who have not caught the disease, the knowledge of preventive measures seems to be the most powerful weapon at hand.
Since the discovery of the first AIDS patient in 1985, the number of HIV carriers is on an alarming rise in China and statistics show that young people are the more likely victims of AIDS. Nationwide there are 214 million people between the ages of 13 and 22, most of whom are students. If no measures are taken to protect these young people, it is almost certain that the threat of AIDS will be very real to them. There has been a great deal of misinformation concerning the transmission of AIDS.
One of the most misleading myths is that AIDS can be transmitted by casual physical contact such as kissing, shaking hands or sharing food container. Surveys and investigations conducted in some universities and colleges show that half of those people questioned are not clear about how AIDS is transmitted, not to mention how it is prevented.
This is the driving force behind the State Education Department’s decision to spread AIDS awareness information among college students and later to high school students and primary school students.
69．Why does the passage say that AIDS is a deadly disease?
A．Because it destroys the immune system of the human body.
B．Because the AIDS patients cannot resist the disease and will die.
C．Because the doctors now find no medicine to cure AIDS.
D．All of the above.
70．By writing “This is only one side of the story”, the author suggests that_____.
A．although we can’t cure AIDS, we can manage to prevent it.
B．AIDS is very dangerous, but we should not be scared of it.
C．AIDS is not curable, but doctors should not give up fighting against it.
D．although the doctors cannot cure the disease, they can help improve the patients’ health.
71．What can be concluded from the surveys and investigations mentioned in the passage?
A．No college students know how people become AIDS victims.
B．50 percent of college students do not know how to prevent AIDS.
C．Many college students are not aware how people become AIDS victims.
D．Many college students did not mention AIDS prevention in the surveys and investigations.
72．What is the best title of this passage?
A．China Fights AIDS             B．Young People—Most likely AIDS Victims
C．AIDS Information Is Necessary   D．AIDS—A Deadly Disease
