閱讀下面短文，并根據(jù)短文后的要求答題（請注意問題后的字?jǐn)?shù)要求）。
[1]Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (認(rèn)知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop—a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory: intelligence may be linked to infectious-disease rates.
　　[2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body—and therefore brain—is parasitic (由寄生蟲引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (輸送) to the immune system to fight the infection.
　　[3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.
　　[4]If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.
小題1:What is the main idea of the text？(no more than 10 words)________________________
小題2:Complete the following statement with proper words.(no more than 4 words)
　　Those countries that have the ________________ are always at the bottom of the  IQ list.
小題3:Fill in the blank in Paragraph 2 with proper words.(no more than 5 words)

Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf’s howl and it appears that there may be more to discover.      One theory is that wolves howl to bend better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior.     Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be “punished” for
Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ——Why do welves howl for sure?
What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering.
Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of “roll rall”where wolves all howl togeter to howl, very likely others will follow.

Crossroads International
How does Crossroads work?
Crossroads is a resource network. We take goods Hong Kong doesn’t want and give them to people who badly need them. We collect those goods and give them out in the welfare arena(福利院) in Hong Kong, Mainland China, elsewhere in Asia, Eastern Europe and Africa. So Crossroads is just that: a Crossroads between need and resource.
Who do we help?
The welfare agencies we help do not run on large budgets(預(yù)算). They are grass-root groups who have seen a need and tried to meet it. They can’t get the job done without back-up, though, so our task is to help them do their task. Our warehouse is full of goods, from computers to high chairs, clothing to books, stationery(文具) to medical provision, cupboards to dinning sets. They send us a list of their needs and we try to match it with the resource we have in stock.
How do we operate?
Crossroads itself also operates on a low budget. We do not buy the goods we send. They are donated. Similarly, rather than raising funds for freight(貨運(yùn))，we ask transport companies to donate their services. Nobody in our organization receives a salary. Even our full-time staff works on a voluntary basis.
Those that donate goods and services:
·Factories·Manufacturers ·Hospitals ·Hotels ·Householders
·Offices ·Other Charities ·Transport Companies ·Educational Institutions
One resource that we are always in need of is people. While we receive large quantities of goods and there is never a short supply of requests for them, we are always in need of hands to help sort and prepare them for shipping.
What can I do?
We are always in need of people. We have a lot of tasks. If you are volunteering regularly, we can offer work in some of the following categories, some of the time. You are welcome to number your top three choices and we will do our best to accommodate them.
·Clothing categorization ·Sewing ·Toy categorization ·Furniture handling
·Driving ·Book categorization ·Household goods categorization ·Office work
·Electrical goods categorization ·Book keeping ·Fund- raising
·Stationery categorization ·Medical categorization
Where to find us?
All volunteer work is done at out warehouse:
Located in Basement Zone M of the Kai Tak Government Building
Our warehouse hours: Tues.-Sat. 10:00am-5:30pm
Postal address: 16 Man Tong, Silvermine Bay, Lantau Island, HK
Office details: Ph: 2984 9309, 2740 9657

Social networking websites are causing alarming changes in the brains of young users, a famous scientist has warned．Sites such as Facebook, Twitter and Bebo are said to shorten attention spans （幅度）, encourage instant satisfaction and make children more self-centered．
Warnings from neuroscientist （神經(jīng)系統(tǒng)科學(xué)家） Susan Greenfield will disturb the millions whose social lives depend on surfing their favorite websites each day．But they will strike a chord （弦） with parents and teachers who complain that many teenagers lack the ability to communicate or concentrate away from their screens．
More than 150 million use Facebook to keep in touch with friends, share photographs and videos and post regular updates of their movements and thoughts．A further six million have signed up to Twitter, the "micro-blogging" service that lets users exchange text messages about themselves．But while the sites are popular and extremely profitable, a growing number of psychologists and neuroscientists believe they may be doing more harm than good．
Baroness Tarot, an Oxford University neuroscientist believes repeated exposure could rewire the brain．Computer games and fast-paced TV shows were also a factor, she said．"My fear is that these technologies are weakening the brain to the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and live for the moment．" "I often wonder whether real conversation in real time may eventually give way to these easier and faster screen dialogues, in much the same way as killing and butchering an animal to eat has been replaced by the convenience of packages on the supermarket shelf," she said．
Psychologists have also argued that digital technology is changing the way we think．They point out that students no longer need to plan their term papers before starting to write—thanks to word processors they can edit as they go along．
A study by the Broadcaster Audience Board found teenagers now spend seven and a half hours a day in front of a screen．Educational psychologist Jane Healy believes children should be kept away from computer games until they are seven．Most games only excite the "flight or fight" areas of the brain, rather than the areas responsible reasoning．
Sue Palmer, author of Toxic Childhood, said: "We are seeing children's brain development damaged because they don't engage in the activity they have engaged in for thousands of years．I'm not against technology and computers．But before they start social networking, they need to learn to make real relationships with people．"
小題1:.
According to the passage, social networking websites might _____．
A．make young users more selfish
B．lengthen young users' attention span
C．encourage young users constant satisfaction
D．help young users communicate better with their families
小題2:.
A neuroscientist may worry that sites like Facebook may ______．
A．help children learn to make real relationships with people in society
B．encourage students not to plan their term papers before starting to write
C．disturb those whose social lives depend on surfing their favorite websites
D．make real conversation in real time give way to easier and faster screen dialogue
小題3:.
From the passage we can infer that _____．
A．Baroness Tarot agrees websites cause small children's small attention span
B．Jane Healy believes computer games can do good to children's reasoning
C．Susan Greenfield's warnings have been brought to wide public attention
D．Sue Palmer's book Toxic Childhood discusses the development of networking
小題4:.
What is the purpose of this passage?
A．To tell us the conflict between neuroscientists and psychologists on websites．
B．To present some negative opinions on social networking websites．
C．To offer advice on the problem of brain damage caused by social networking．
D．To analyse how social networking websites cause damage in the brains of teenagers．

Sometimes children do not do what their parents tell them to do. When this happens, a parent tries to help the child to do the right thing. When this does not work, the parent usually punishes the child.
There are many things that a parent can do. One thing that people have done is to spank (打屁股) the child. When a parent spanks a child, they will use their hand or a hard object to strike them on their bottom. This is meant to show the child that they have done something wrong.
One parent remembers being spanked when he was a child. His parents used a wooden spoon. When he spanked his own children with his hand, he saw that he put a red mark on his child’s leg. He never did that again.
One problem with spanking is that it teaches the child to hit someone when they do not like what the other person is doing. Another problem with spanking is that the parent is usually angry and can hit the child too hard. Sometimes parents will use spanking for everything and not try other ways to get the child to do the right thing.
Many parents are not sure of what to do instead of spanking. Some people think that their religion tells them that spanking is okay. Some think that the law lets them do it. The courts (法院) say that parents have the right to teach their children how to behave.
Other things should be tried before a parent decides to spank a child. Telling the child exactly what is wanted from them can be one thing. Giving a child more than one choice is another thing that can be tried. Getting down to the child’s level and taking a more child-friendly approach (方法) can help as well.
小題1:According to the passage, when children do something wrong, one thing that parents usually do to punish them is to ________.
A．strike them on the bottomB．try to help them do the right thing
C．teach them what to doD．take them to court
小題2: Which of the following is NOT the problem caused by spanking?
A．It teaches the child to hit others when they offend（使人不快） him or her.
B．The parent may get angry and hit the child too hard.
C．Sometimes parents may use spanking for everything.
D．It makes parents try other ways to make the child do right.
小題3:Which of the following can best describe the writer’s attitude towards spanking?
A．favorableB．indifferentC．interestedD．unfavorable
小題4:From this passage, we can conclude that ________.
A．Good children always do the right thing.
B．Parents should try their best to avoid spanking their children.
C．Parents have no choice but to spank their children when they do something wrong.
D．Children can have more than one choice to avoid being spanked.

It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world.
The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(證明…有罪) murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child.
Jeffrey said he and his colleagues made the discovery by accident while tracking genetic variations(變異). But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents’ son.·In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man.
DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person’s privacy. That includes a person’s medical history, racial origin or psychological profile. “There is the long-term risk that people can get into these samples and start getting additional information about a person’s paternity(父子關(guān)系) or risk of disease,” Jeffrey said.
DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals’ DNA profiles matching in the most commonly used tests at one in a billion.
小題1:According to the text, DNA testing can NOT be used in _______ .
A．doing criminal investigationsB．deciding faraily law
C．clearmg wrongly accused people D．telling twins apart
小題2:DNA samples are not popular with all the people because _______ .
A．the government in Britain establishes a criminal database
B．the US and Canada develop similar systems
C．DNA samples can be used to harm a person’s privacy
D．DNA testing is too expensive and dangerous now
小題3:Where will you most probably find this article?
A．In a guidebook. B．In a storybook.
C．In a science fiction. D．In a scientific magazine.
小題4:Which is the best title for the passage?
A．Discovery of DNA testing by JefferyB．Practice of DNA testing in court
C．DNA testing in the present situationD．Benefits and side effects of DNA testing

By 2050
Futurologists predict that life will probably be very different in 2050.
TV channels will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.
Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.
Robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots—they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.
Medical technology will have conquered many diseases. Today, there is equipment that connects directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.
Scientist will have discovered how to control genes（基因）. Scientists have already produced clones(克隆) of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
