For some people, the sight of a mouse can be reason to scream. For other mice, the same sight can be reason to sing.
Mice will probably   21  sing their way to any concert, but researchers in the United States have found   22  that mice do,   23 , sing.
Scientists already knew that mice make ultrasonic(超聲波) sounds—noises that are too high-pitched(高音的) for people to hear   24  special equipment.
To find out whether mice put such sounds together in song-like   25 , the researchers recorded the sounds of 1 mice. Using computer   26 , they were able to separate the sounds into specific types of syllables(音節(jié)), and found the mice produced about 10 syllables per second.
The results showed that nearly all of the mice repeated sequences(順序) of syllables in different patterns. That’s enough to meet the definition of what scientists   27  song. But not all scientists are   28  _ that what the mice are doing is   29  singing. To prove it, the researchers must show that there’s learning involved. And, they need to __  30  why the mice sing.

London——Laura Spence has excellent grades, a place at Harvard University and a US $25,000 a year scholarship. The British Government says that is scandal(丑聞).  
Not because the 13-year-old girl is going to Harvard, but because she was rejected by Oxford University. Her case makes people talk about the long-running problems about elitism(精英主義) in British education.
“I think it’s a scandal if a child has to go to Harvard rather than getting into Oxford, don’t you?” Education Secretary David Blunkett said on May 26th in an interview on BBC radio.
British Treasury chief Gordon Brown said in a speech on May 25th it was “an absolute scandal”, a girl with those grades was turned down by Oxford’s Magdalen College. He noted that Spence comes from Monkseaton in northeastern England, where people sometimes complain they get fewer chances than people living in the richer, more populous south.
Oxford and Cambridge University now take the majority of their students—53 percent—from publicly funded schools. Elite(精英)private schools such as Eton and Harrow account for the other 47 percent, even though they serve only 7 percent of secondary students.
A BBC reporter had seen notes of Spence’s interview at Magdalen. “As with other comprehensive school pupils, she’s low in confidence and difficult to draw out of herself in spite of being able to think on her feet,” the BBC quoted the notes as saying. Still, the notes concluded that Spence “will be an excellent doctor.”
“It appears as if some of our institutions have admissions procedures which may be because of absurd prejudices against children from comprehensive schools…are not giving these children a fair crack of the whip”, Education Minister Wicks told the BBC.
5.Laura Spence was rejected by Oxford University because.
A.she was a girl of 13 years old       B.she lacked confidence and she couldn’t think by herself
C.she didn’t win excellent grades
D.she was a shy girl from a comprehensive school in the poorer, less populous north
6.If Laura Spence was from such a school as Eton,.
A.she would be admitted to Oxford    B.she would be accepted by Harvard
C.she could cause long?running problems about elitism in British education
D.she wouldn’t be an excellent doctor
7.What’s the meaning of “a fair crack of the whip”in the last paragraph?
A.A good chance.        B.Warning.           C.Rejection.             D.Admission
8.According to Education Minister Wick’s words, we know he .
A.thought there was something wrong with procedures of admissions to their institutes
B.took the side of Oxford University

What time is it? Most people are pretty accurate in their answer. And if you don’t know for sure, it’s a very likely that you can find out. There may be a watch on your wrist, there may be a clock on the wall, desk, or computer screen; or maybe you’re riding in a car that has a clock in the dashboard (儀表板).
Even if you don’t have a timepiece of some sort nearby, your body keeps its own beat. Humans have an internal clock that regulates (調(diào)節(jié)) the beating of our heart, the pace of our breathing, the discharge (排出) of chemicals within our bloodstream, and many other bodily functions.
Time is something from which we can’t escape. Even if we ignore it, it’s still going by, ticking away, second by second, minute by minute, hour by hour. So the main issue in using your time well is, “Who’s in charge?” We can allow time to slip by and let it be our enemy. Or we can take control of it and make it our ally.
By taking control of how you spend your time, you’ll increase your chances of becoming a more successful student. Perhaps more importantly, the better you are at managing the time you devote to your studies, the more time you’ll have to spend on your outside interests.
The aim of time management is not to schedule every moment so we become slaves of a timetable that governs every waking moment of the day. Instead, the aim is to make informed choices as to how we use our time. Rather than letting the day go by, largely without our awareness, what we are going to discuss next can make us better able to control time for our own purposes.
小題1:The underlined word “ally” in Para. 3 more likely means somebody or something that is _________.
A．your slave and serves you
B．your supporter and helps you
C．under your control and obeys you
D．under your influence and follows you
小題2:The author intends to tell us that time _____________.
A．could be regulated by a timepiece such as a clock or a watch
B．could be managed by the internal clock of human bodies
C．should be well managed for our own interest
D．should be saved for outside interests
小題3: In the next part, the author would most probably discuss with you ________.
A．how to keep up with the timesB．how to make up for lost time
C．how to have a good timeD．how to make good use of time

A mobile phone is no longer just a phone -- it is also a music player, video camera and personal organizer. And mobile phones with television programming are just around the corner. But the more functions cell phone manufacturers add, the greater the amount of power the phones use and the less practical running them on lithium (鋰) batteries becomes -- so the race to find a viable alternative is on.
Two of the world's biggest electronics makers, Hitachi and Toshiba, are currently competing against each other to come up with an alternative, most likely to be micro fuel cells. The task has been set by Japan's second largest mobile phone provider, KDDI, which wants its customers to soon be able to use special television programming on their handsets, and has asked the two electronics companies to come up with a better power source. Hitomi Murakami, of KDDI, says battery-operated mobile phones cannot keep up with the new applications. "We're looking at various ways to expand content and services that we can provide to the people. And we don't want to have battery issues delaying us from doing that," he says.
Hitachi's Atsushi Morihara says it is a critical race for both of the companies as the resulting product will have a major impact on the mobile market in the future. "We are in competition and it's up to both of us to come up with a good product. A product that will satisfy KDDI's needs. I think I can go as far to say that the winner will take all."
Miniaturized direct methanol (甲醇) fuel cells are different batteries in that they create power instead of simply storing it. That power is made by new technology utilizing cheap methanol. If all gees to plan, come 2007, Japanese phone users will not use an electric charger to power their mobiles, they will instead carry a small bottle of methanol and with just a few squirts, they will have power for their phones. But the method has its downsides, including how passengers will be able to take small mounts of flammable methanol on airliners. Fumio Ueno of Toshiba says that once developed, the uses of miniaturized direct methanol fuel cells have endless possibilities.
小題1:The lithium batteries are becoming improper for the cell phone because ______.
A．there is a television in the phoneB．it is inconvenient to use
C．it can't provide enough powerD．people have found substitutes
小題2:According to the passage, Toshiba ______.
A．is in critical competition with KDDI
B．will probably beat its rival
C．a(chǎn)ttaches great importance to methanol fuel
D．is one of the largest battery provider
小題3:Which of the following is NOT the characteristic of methanol fuel?
A．Easy to catch fire.B．Portable.
C．Inexpensive.D．Available everywhere.
小題4:The best title for the passage is ______.
A．Search for better phone power.
B．Development of cell phone battery.
C．Competition between two electronic firms.
D．Advantage and disadvantage of methanol fuel.

A wise man once said that the only thing necessary for the victory of evil is for good men to do nothing. So, as a police officer, I have some urgent things to say to good people. Day after day my men and I struggle to hold back a tidal wave of crime. Something has gone terribly wrong with our once-proud American way of life. It has happened in the area of values. A key ingredient is disappearing, and I think I know what it is: accountability.
Accountability isn’t hard to define. It means that every person is responsible for his or her actions and liable for their consequences.
Of the many values that hold civilization together --- honesty, kindness, and so on --- accountability may be the most important of all. Without it, there can be no respect, no trust, no law --- and, ultimately, no society.
My job as a police officer is to impose accountability on people who refuse, or have never learned, to impose it on themselves. But as every policeman knows, external controls on people’s behavior are far less effective than internal restraints such as guilt, shame and embarrassment.
Fortunately there are still communities --- smaller towns, usually --- where schools maintain discipline and where parents hold up standards that declare: “In this family certain things are not tolerated --- they simply are not done!”
Yet more and more, especially in our larger cities and suburbs, these inner restraints are loosening. Your typical robber has none. He considers your property his property; he takes what he wants, including your life if you annoy him.
The main cause of this breakdown is a radical shift in attitudes. Thirty years ago, if a crime was committed, society was considered the victim. Now, in a shocking reversal, it’s the criminal who is considered victimized: by his underprivileged (被剝奪基本社會權(quán)利的) upbringing, by the school that didn’t teach him to read, by the church that failed to reach him with moral guidance, by the parents who didn’t provide a stable home.
I don’t believe it. Many others in equally disadvantaged circumstances choose not to engage in criminal activities. If we free the criminal, even partly, from accountability, we become a society of endless excuses where no one accepts responsibility for anything. We in America desperately need more people who believe that the person who commits a crime is the one responsible for it..
小題1:What the wise man said suggests that it’s __________.
A．unnecessary for good people to do anything in face of evil
B．certain that evil will be widespread if good men do nothing about it
C．only natural for good men to defeat evil
D．desirable for good men to keep away from evil
小題2: According to the author, if a person is found guilty of a crime, ________.
A．society is to be held responsible
B．modern civilization is responsible for it
C．the criminal himself should bear the blame
D．the standards of living should be improved
小題3:  Compared with those in small towns, people in large cities have ________.
A．less self-disciplineB．better sense of discipline
C．more respect to each otherD．less effective government
小題4: The writer is sorry to have noticed that ________.
A．people in large cities tend to excuse criminals
B．people in small towns still stick to old discipline and standards.
C．today’s society lacks sympathy for people in difficulty
D．people in disadvantaged circumstances are engaged in criminal activities
小題5: The key point of the passage is that ________.
A．stricter discipline should be maintained in schools and families
B．more good examples should be set for people to follow
C．more attention should be paid to people’s behavior
D．more people should accept the value of accountability

People have wondered for a long time how their personalities and behavior are formed. It is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive. 
Social scientists are of course extremely interested in these types of questions. They want to explain why we possess certain characteristics and exhibit certain behavior. There are no clear answers yet, but two distinct schools of thought on the matter have developed. As one might expect, the two approaches are very different from each other, and there is a great deal of debate between proponents of each theory. The controversy is often conveniently referred to as “nature and nurture”．
Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological factors. That our environment has little, if anything, to do with our abilities, characteristics and behavior is central to this theory. Taken to an extreme，this theory states that our behavior is predetermined to such a great degree that we are almost completely governed by our instincts(本能)．
Proponents of the “nurture” theory, or, as they are often called, behaviorists, claim that our environment is more important than our biologically based instincts in determining how we will act. A behaviorist, B. F. Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings. The behaviorists' view of the human being is quite mechanistic. They state that, like machines, humans respond to environmental stimuli (刺激) as the basis of their behavior. 
Socially and politically, the consequences of these two theories are far-reaching. In the US，for example, blacks often score below whites on standardized intelligence tests. This leads some “nature” proponents to conclude that blacks are genetically lower in status than whites. Behaviorists, on the contrary, say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy, and that, as a result, they do not develop the same responses that whites do.
Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes and that the controversy will continue for a long time is certain. 
小題1:This passage is mainly concerned with ________.
A．relation between personality and behavior
B．relation between behavior and environment
C．different accounts of patterns of human behavior
D．different theories of the formation of human behavior
小題2:The underlined word “proponents” in Paragraph 2 means ________.
A．creatorsB．a(chǎn)dvisorsC．a(chǎn)dvocatesD．judges
小題3:In Paragraph 5, the author mainly writes about ________.
A．the considerable influence of the two theories
B．differences between the blacks and whites
C．racial discrimination in the United States
D．different responds to intelligence tests
小題4:What's the author's purpose in writing the passage?
A．To call our attention to the changes of human behavior.
B．To urge scientists to do more research in social science.
C．To give us a detailed explanation of human behavior.
D．To present an argument in the field of social science.

We all like watching online videos of dogs and cats doing funny things. But if you had to decide, which of the two animals would you say you might like better? Your answer may say something about your personality.
According to a 2010 study led by Sam Gosling, a scientist at the University of Texas, US, dog people are about 15 percent more outgoing and 13 percent more pleasant to be friends with than cat people.
This is not hard to understand, since cats and dogs behave differently themselves. “Cats will occasionally engage in social activities, but usually after only a few minutes, they will abandon the game. Dogs, on the other hand, will often engage in play, like fetching a thrown ball, for hours at a time,” said Modern Dog Magazine.
Although cat people are less social, Gosling’s study showed that they are 11 percent more open-minded than dog people. They usually like art, adventures and unusual ideas. They also have more imagination and curiosity. But dog people are more likely to stick to old beliefs and traditional interests.
However, their love of a free lifestyle also means that cat people dislike making plans. They just follow whatever ideas pop into their heads without planning ahead. But dog people are different. They usually have strong self-control and like to carry out their plans.
Despite these big differences between dog people and cat people, there are some things that they have in common, “Both types of people consider themselves close to nature, dislike animal-print clothing, and are generally optimists,” noted Mother Nature Network.
But can personality change? Can a cat person become a dog person, or the other way around? In a study done by Stanley Coren, a scientist based in Canada, he asked cat owners: “If you had enough living space and there were no objections form other people in your life, and someone gave you a puppy as a gift, would you keep it?”
About 68 percent of them said they would not accept a dog as a pet. But when dog owners were asked the same question about a kitten, almost 70 percent said they would allow a cat into their lives.
小題1:According to the article, dog people _____________ cat people.
A．perform better in school than B．a(chǎn)re more open-minded than
C．have closer friends thanD．a(chǎn)re more traditional than
小題2:The underlined phrase “engage in” in Paragraph 3 probably means_____________.
A．take little interest in B．take part in C．benefit fromD．suffer from
小題3:What do cat people and dog people have in common?
A．Both of them like planning ahead
B．Both of them love travelling and adventures
C．Both of them are imaginative and curious
D．Both of them care about nature.
小題4:What can we conclude from the last two paragraphs?
A．Cat people are more likely to become dog people.
B．Dog people are more likely to accept cats into their homes than cat people are to accept dogs.
C．Neither dog nor cat people like to accept a new pet.
D．It is difficult to find out whether dog people or cat people will make a change.
