The 2009 outbreak of HINI is a new kind of influenza virus, commonly referred to as “swine flu”. It is thought to be a break of four known kinds of influenza. A virus subtype H1N1: one endedmic(流行病) in humans, one endemic in birds, and two endemic in pigs (swine). The source of the outbreak in humans is still unknown, but cases were first discovered in the U.S. and soon after in Mexico.
According to the U.S. Centers for Disease Control and Prevention(CDC),it is not yet clear how serious this new virus actually is compared with other influenza viruses, although on May 26 they stated that new cases in the U.S. have probably reached the hightest point, and most cases have so far been mild relative to “seasonal flus”. But because this is a new virus, most people will not have immunity(免疫性) to it, and illness may eventually become more severe and widspread. The H1N1 flu mainly spreads in the same way that regular “seasonal influenza” spreads through the air from coughs and sneezes or touching those infected. It cannot be transmitted from eating cooked pork or by being in close contact with pigs.
As yet there is no vaccine(疫苗) available to prevent infection although companies are in the planning stages for having one available later this year. But there is concern that the virus could vary again over the coming months, leading to a new and potentially more dangerous flu outbreak later in the year, and a vaccine that will be less effective in preventing its spread.
As of May 27, the virus had spread to more than 50 countries; however, over 80% of reported deaths have taken place in Mexico. According to the CDC, the fact that the flu’s infection activity is now monitored more closely may help explain why more flu cases than normal are being recorded in Mexico, the United States and other countries.    
1. The 2009 outbreak of H1N1 is thought to      .
A.be concerned with four endmics                                             
B.have come from the virus from pigs
C.occur because of unknown virus in Mexico
D.be caused because of people without immunity
2.According to the U.S. Centers for Disease Control and Prevention, ______.
A.most people won’t be infected with the flu                                           
B.the H1N1 will not be too mild to cause many deaths in the world
C.the present situation allows of no optimist
D.H1N1 can be transmitted by touching pigs                             
3.To make people worried more is that      .
A.no effective vaccine can prevent the virus from spreading
B.the virus will mutate in the following months
C.a seasonal influenza will break out
D.the newly-developed vaccine will lose effectiveness
4.From the passage we can learn that      .
A.every country is watching closely the spreading of the H1N1                        
B.more than one-fourth of the deaths from the H1N1 are in Mexico                          
C.only the United States and Mexico recorded the cased of influenza                                                                     
D.effective medicine has been produced to cure the H1N1

Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with high energy density(密度)”,said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.
1. Which of the following is true of Jae Kwon?
A. He teaches chemistry at MU. 
B. He developed a chemical battery.
C. He is working on a nuclear energy source.
D. He made a breakthrough in computer engineering.
2. Jae Kwon gave examples in Paragraph 4_________.
A. to show chemical batteries are widely applied.
B. to introduce nuclear batteries can be safely used.
C. to describe a nuclear-powered system.
D. to introduce various energy sources.
3. Liquid semiconductor is used to _________.
A. get rid of the radioactive waste  
B. test the power of nuclear batteries.
C. decrease the size of nuclear batteries
D. reduce the damage to lattice structure.
4. According to Jae Kwon, his nuclear battery _______.
A. uses a solid semiconductor       
B. will soon replace the present ones.
C. could be extremely thin          
D. has passed the final test.
5. The text is most probably a ________.
A. science news report        B. book review   
C. newspaper ad              D. science fiction story

31st October —— A team of British explorers has announced they are going to the North Pole to measure the ice cap’s thickness. The exploration will take ground-based readings (仪表的读数) of an ice formation which most scientists agree is shrinking at an alarming rate.
Explorer Pen Hadow’s three-member team will pull a sled-fixed radar device, which measures ice density every eight centimeters, 2,000 kilometers across the Arctic and will produce millions of readings.
They will leave in February, 2008 and will face temperatures of -50℃ on a journey that will take up to 120 days. They have been testing their equipment in Britain and Canada.
Hadow is excited about the prospects (前景), “For the first time we will be able to transmit video images — webcam film of the expedition — as it unfolds so people can track us, and the whole idea is to engage as many people as we can in what we’re doing.”
New fallen snow on top of the ice makes ground-based measurements more accurate than satellite data.
“It has been in the planning stage for a while,” said Hadow. “We spent the last two years developing impulse radar (冲击雷达), which normally is about 100 kilograms and hangs under an aircraft and so on. We’ve managed to get it down to about 4 kilograms. It’s the size of a briefcase and we are dragging it behind the sled as we go.”
    The ice cap shrank enough in 2007 so that a pathway through the cap known as the Northwest Passage opened up during the melting of the Arctic summer.
Cambridge University’s Joao Rodrigues explains, “Thickness of the ice cap will determine how much solar radiation will be reflected and the heat exchange between the ocean and the atmosphere and it is thus a vital component (成分) of climate models.”
If warming trends continue, some experts predict that the Arctic Ocean could be ice-free during the summer within a few decades.
1 What would be the best title for the text?
A. Exploration to the North Pole.
B. Arctic ice cap shrinking.
C. Arctic ice survey announced.
D. Ground-based measurements of ice.
2. What is special about the exploration?
A. It will be broadcast live on the Internet.
B. Explorers will use a sled-fixed radar device.
C. Explorers will travel in extremely cold conditions.
D. Ground-based measurements are more accurate.
3. What is the purpose of the exploration?
A. To measure the ice cap’s thickness.
B. To study whether ice will disappear in the Arctic.
C. To make a film about the Arctic exploration.
D. To make people interested in what they are doing.
4. It can be inferred from the passage that ________.
A. ice in the Arctic will disappear in ten years
B. the exploration will last for half a year
C. Hadow spent two years developing a kind of radar, which is about 100 kilograms
D. if there is snow on ice, satellites can’t measure the ice thickness accurately enough
5. From the passage, we learn that ________.
A. the explorers will measure ice density every other centimeter
B. people will be able to follow the explorers and see what they are doing  
C. people could go through the Northwest Passage in the 2007 Arctic summer
D. the equipment that Hadow’s team use will be tested in the United States

Professor Martin’s report says that children who attend a number of different schools,because their parents have to move around the country,probably make slow progress in their studies. There are also signs,says Professor Martin,that an unusually large number of such children are mentally affected.
The professor says,“It’s true,my personal feeling is that children should stay in one school. But our findings are based on research and not on any personal feelings. ”
Captain Thomas James,an Army lecturer for the past 20 years and himself a father of two,said,“I’ve never heard of such rubbish. Taking me for example. no harm is done to the education of my children,who change schools regularly—if they keep to the same system,as in our Army schools. In my experience—and I’ve known quite a few of them—Army children are as well adjusted as any others,if not more so. What the professor doesn’t appear to appreciate is the fact that in such situation children will adapt much better than grown-ups.”
When this reached Professor Martin,he said that at no time had his team suggested that all children were backward or mentally affected in some way,but simply that in their experience there was a clear tendency.
“Our findings show that while the very bright children can deal with regular changes without harming his or her general progress in studies,the majority of children suffer from constantly having to enter a new learning situation.”
小题1:Professor’s Martin’s report suggests that      
A.it may not be good for children to change schools too often
B.parents should not move around the country
C.changing schools is the reason of children making slow progress
D.more and more children are mentally affected
小题2: According to the passage,Professor Martin's personal feeling.
A.is the opposite of what his report has shown
B.is in a way supported by his research
C.has played a big part in his research
D.is based on the experience of his own children
小题3:From the passage,we can conclude that Captain James’ children_____.
A.have been affected by changing schools
B.go to ordinary state schools
C.can get used to the Army school education
D.discuss their education regularly with their father
小题4:About children and grown-ups,Captain James says that children____.
A.are generally poorly-adjusted
B.are usually less experienced
C.can adapt much more easily
D.can deal with changes quickly

  When scientists set out to explore the roots of human laughter, some apes(类人猿) were just tickled(胳肢)to help. That’s how researchers made a variety of apes and some human babies laugh. After analyzing the sounds, they concluded that people and great apes inherited laughter from a shared ancestor that lived more than 10 million years ago. Experts praised the work, it gives strong evidence that ape laughter and human laughter are related through evolution(进化).
Scientists have noted that apes make characteristic sounds during play or while being tickled, especially to signal that they’re interested in playing. It’s been suggested before that human laughter grew out of primate(灵长类动物) roots. But ape laughter doesn’t sound like human laughter. It may be slower noisy breathing. So what does that have to do with the human ha-ha? To investigate that, Marina Davila Ross and her colleagues carried out a detailed analysis of the sounds made by tickling three human babies and 21 other primates, apes included.
After measuring 11 features in the sound from each species, they tried to find out how these sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themselves are related, the scientists reported online in the journal Current Biology. They also concluded that while human laughter sounds much different from ape laughter, their typical features could have come from the same ancestor.
Panksepp, who studies laughter-like responses in animals but didn’t participate in the new work, called the paper exciting. Panksepp’s own work concludes that even rats produce laughter in response to playing and tickling, with sounds that can hardly be heard by people. Robert Provine, a scientist, who wrote the book, Laughter: A Scientific Investigation, said the new paper showed some important clues, like ape sounds that hadn’t been realized before.
69. Why did the scientists analyze the laughter made by tickling human babies and apes?
A. To try to discover if they can make characteristic sounds.
B. To see if they interested in playing.
C. To find out if the laughter of apes and humans is related.
D. To find out the differences between humans and apes.
70. Based on Paragraph 3 we can know that researchers measured the features in the sound to ________.
A. find out ape sounds that hadn’t been realized before
B. find out relations among primates’ laughter
C. see what a family tree from each species looks like
D. make a report online in the journal Current Biology
71. What can be inferred from the last paragraph?
A. Panksepp spoke highly of the new research.
B. Rat laughter is likely to be related to ape laughter.
C. Robert Provine provided some new clues for the researchers.
D. Humans don’t enjoy listening to ape laughter.
72. What would be the best title for the passage?
A. Ape study explores evolution of laughter.
B. Apes like to laugh when being tickled.
C. Human laughter and ape laughter are different.
D. Laughter: A Scientific Investigation.

Working hard for fun
No more pencils! No more books
No more teacher’s serious looks!
After a long period of study and work, the young Americans burst through the school doors singing.
But unfortunately, American students do very poorly and are among the worst students in the world. In the entire field of subjects---from geography and maths to science and general knowledge. American students are the poorest performers. Why? What’s the reason behind the scene? One problem lies in the fact that so little is expected from them. The standards of success are too low. Teachers are not willing to give out low grades and fail students. Besides, the existing negative results are few and mean little to students if their performance in study is poor . Of course some students realize that a high school diploma is a measure of success and will be important to get a job or get admitted into college. But they only have to go through the motions without really trying. They learn to get by with a minimum of effort.
In America, it is simply too easy for high school students to enter college. This forms a sharp contrast with the students in China and other Asian countries who have to suffer heavy pressure from parents, teachers and cruel social facts. Chinese students have to study hard for long years to pass the national college entrance examination which few Americans will take such trouble to enter to university. The majority American students know that they will be able to get into some college, so they do not really worry about it.
It turns out that American high school students are just too busy to find time to study. They spend almost no time on study while students from other countries spend four or five hours per day on homework. American students on the average give less than five hours per week to their studies. Learning and reading for future are not important to them. Many American never read. It is little wonder why Americans knows less than students from other countries.
1. Why are American students the poorest performers in the entire field of subjects?
A. Because they are too busy to find time to study.
B. Because they are too stupid and too lazy.
C. Because they care little about their study.
D. Because so little is required from them
2. Which of the following is Not true ?
A. Most of American students spend less than five hours on their study every week.
B. Few American students have trouble to enter college.
C. American students can be admitted into college even without a high school diploma.
D. It is hard for the students in China to enter college.
3. What seems to be the writer’s attitude towards American students?
A. He probably thinks much should be expected from them.
B. He is in favour of American students’ learning methods.
C. He shows no interest in American students’ study.
D. He thinks American students study hard.

A new system that scans customers’ fingerprints and deducts (扣除) the grocery bill from their bank accounts has taken supermarkets in southwestern Germany by storm and is being picked up by hardware stores, school restaurants and even bars are picking it up.
The Edeka supermarket chain is the first retail (零售) business in Germany to use the new system. “Almost a quarter of our customers pay with their fingers,” said an employee at the headquarters. Edeka has tried the system at 70 of its supermarkets and customers like it.
“At first we thought that only the young who really keep up with the latest technology would be interested, but we were wrong,” said Stefan Sewoester from IT Werke. “Almost two-thirds of the people who use the system are 40 and older,” he said.
IT Werke, a computer company, is one of the pioneers of fingerprint payment software in Germany. It has helped about 150 shops, restaurants and bars to put in the fingerprint scanning machines.
To sign up for the service, customers must have their fingerprints taken and leave their addresses and banking details with the shop. The shop then takes the cost of goods directly out of the customer’s bank account.
“It is a godsend for elderly people because they do not have to remember their pin-code to pay with their bank cards, or to look around for their glasses or cash.” Sewoester said.
The stores benefit from the system, too. It saves more than time in the check-out line. It also cuts out the hidden costs of accepting electronic card payments.
Fingerprint date profiling has long been used to control access and for other security purposes in Germany’s airports, laboratories and nuclear power plants. IT Werke plans to keep refining the retail use of the system. It wants to introduce fingerprint payment in school restaurants with an additional feature that might appeal to parents-they could disable their children’s access to junk food.
1. Which of the following can be the best title of the passage?
A. Pay with Fingers.                                                B. New Development in Technology.
C. Supermarket Revolution.                                 D. Change in Computer Software.
2. Most of the people who use the fingerprint system are ______.
A. youngsters                B. housewives               C. IT fans              D. the elderly
3. The underlined word “godsend” probably means ______.
A. great fortune     sent by God                          B. good luck sent by God
C. good things that happen unexpectedly                    D. gift sent by God
4. What do we know by inference from the passage?
A. Fewer shops will try the new software because of the cost.
B. The new service requires certain personal information.
C. IT Werke should be the largest computer company in Germany.
D. The new change in payment only benefits elderly people.

In nineteen ninety-nine, twelve percent of public elementary schools in the United States required students to wear uniforms. Just three years later, estimates were almost double that.
A study of six big-city Ohio public schools showed students who were required to wear uniforms had improved graduation, behavior and attendance rates. Academic performance was unchanged.
Some middle and high schools in Texas have also joined the movement. Yet studies find mixed results from requiring uniforms. And some schools have turned away from such policies.
Supporters believe dressing the same creates a better learning environment and safer schools. The school district in Long Beach, California, was the first in the country to require uniforms in all elementary and middle schools. The example helped build national interest in uniforms as a way to deal with school violence and improve learning.
Findings in Long Beach suggested that the policy resulted in fewer behavior problems and better attendance. But researcher Viktoria Stamison, who has looked at those findings, says they were based only on opinions about the effects of uniforms.
She says other steps taken at the same time to improve schools in Long Beach and statewide could have influenced the findings. The district increased punishments for misbehavior. And California passed a law to reduce class sizes.
In Florida, for example, researcher Sharon Pate found that uniforms seemed to improve behavior and reduce violence. In Texas, Eloise Hughes found fewer discipline problems among students required to wear uniforms, but no effect on attendance.
Sociologist David Brunsma has studied school uniform policies since nineteen ninety-eight. He collected the reports in the book. In his own study, he found that reading and mathematics performance dropped after a school in rural Pennsylvania required uniforms.
Political and community pressures may persuade schools to go to uniforms to improve learning. But David Brunsma and others believe there is not enough evidence of a direct relationship. In fact, he says requiring uniforms may even increase discipline problems.
52. What’s the main idea of this passage?
A. More and more students are required to wear uniforms in the US.
B. Wearing uniforms contributes to good academic performance.
C. Researchers in the US argue for school uniform policies.
D. Evidence for school uniform policies in the US is seen as weak.
53. Which was/were the first in the US to require uniforms in all elementary and middle schools?
A. Six big-city Ohio public schools.
B. The school district in Long Beach, California.
C. Some middle and high schools in Texas.
D. Some elementary and middle schools in Florida.
54. Which of the following researchers are NOT supporters of school uniform policies?
A. Viktoria Stamison and Sharon Pate.  
B. Sharon Pate and David Brunsma.
C. Eloise Hughes and Sharon Pate.  
D. Viktoria Stamison and David Brunsma.
55. The underlined word “misbehavior” in the sixth paragraph probably means ______.
A. serious crime            B. bad performance
C. absence for class       D. action against wearing uniforms
56. We can infer from the passage that ______.
A. more work is needed to get better information about uniform’s effect
B. the number of schools requiring uniforms in the US will decline sharply
C. wearing uniforms has little to do with behavior and learning
D. politicians and communities won’t vote for uniform policies
