What exactly is intelligence? There aren’t any easy answers．Despite the progress that has been made in genetics and psychology, human intelligence has remained one of the most controversial areas of modern science，until now, that is, for the discovery of a gene linked to intelligence has made the experts think again．
Robert Plomin of the Institute of Psychiatry in London and his colleagues in the US have been looking into genetic make-up．From their research, they have discovered that a slightly different gene is more common in those with a high IQ．Plomin analyzed DNA from two groups of 51 children aged between 6 and 15．What he found was that the first group had an IQ of 136, putting them in the top 5% of the population, while the other group had an average IQ of 103．An analysis of their genes showed that 32% of children in the higher group had the gene in question, while only 16% in the second group did．However, there is a lot more research to be done, and Plomin himself is cautious at this early stage．He suggests that there are probably many genes that contribute to intelligence, rather than just one. Several studies have shown a strong link between IQ and career success, although some psychologists remain unconvinced about this．Professor Michael Rowe, who has written a book called Genius Explained, is one of these．“The people with the highest IQs are not usually the ones who do best in their careers．”
Many psychologists now believe that when it comes to intelligence, IQ isn’t everything．Many alternative views have been put forward recently．One example is the idea of multiple intelligences, which was developed in the 1980s by Harvard psychologist Howard Gardner．This offers a much broader view than the IQ theory, including creativity and communication skills as relevant factors in intelligence．
Tony Buzan, brain expert and author of Master your Memory, is enthusiastic about this belief, arguing that true geniuses do indeed appear to combine high levels of each type of intelligence．He lists Alexander the Great, Pablo Picasso and Albert Einstein as examples．At the same time, Buzan believes that everyone can develop their intelligence, only if they take the trouble to exercise their brain．Perhaps there’s hope for us all!

解析试题分析：文章介绍了什么是智力？尽管这方面在遗传和心理方面取得了很大的进步，但这一话题仍是现代科学最有争议的话题之一，基因的组成被发现以后，遗传对智力的影响成了科学上研究的一个重要方面。同时也说明了智力并不只是受一个方面的影响，因此下文中又出现了多元智力。
【小题1】B细节理解。One example is the idea of multiple intelligences, which was developed in the 1980s by Harvard psychologist Howard Gardner．This offers a much broader view than the IQ theory,句意为：其中的一个例子就是多元智力，它是在二十世纪八十年代由哈佛心理学家Howard Gardner发起的，这就提供了比智商理论更为广阔的观点。所以答案应是多元智力，故为B。
【小题2】C细节理解题。From their research, they have discovered that a slightly different gene is more common in those with a high IQ．从他们的研究中，他们已经发现，在高智商的这些人中，他们的基因都有稍微的不同这点是相同的。．An analysis of their genes showed that 32% of children in the higher group had the gene in question,分析显示，在高智商的小孩儿中有百分之三十二都有思考问题的基因。所以下文他们用的数据是为了来证明这一观点。故答案应为C。
【小题3】B细节理解题。Many psychologists now believe that when it comes to intelligence, IQ isn’t everything．Many alternative views have been put forward recently．One example is the idea of multiple intelligences, which was developed in the 1980s by Harvard psychologist Howard Gardner．许多心理学家认为，当谈到智力的时候，智商并不代表一切，许多新的观点已经被提出，其中包括多元智力说。由此可知Howard Gardner认为，智力包括多个因素是正确的。故答案为B
【小题4】D综合理解题。由文章的第一自然段What exactly is intelligence?开篇，下文均是围绕这一问题展开，由此可知答案为D。

Scientists Alan M．Goldberg and Thomas Hartung describe recent advances in replacing the use of animals in toxicology(毒物学)testing．Improvements in cell and tissue culture technologies，for example，allow a growing number of tests to be performed on human cells alone．Computer models are becoming increasingly complex and many could one day become more accurate than trials in living animals．
Since the late 1990s，Huntingdon Life Sciences--a company that conducts testing of substances on animals conducted by the Environmental Protection Agency and the Food and Drug Administration—has become a proving ground for aggressive strategies by animal-rights militants （好战分子）．At a hearing，a Senate．committee listened to testimony（证词） against Huntingdon employees and financial institutions providing services to the company．One experimentation witness at the hearing insisted that any means necessary were justified（辩护） to spare animals’ lives；he has previously accepted the idea of murder to that end．
Use of animals in testing and in biomedical research continues to be necessary in many instances and is ethically（伦理道德地）preferable to experimenting on humans or giving up cures that could save human lives．But for the sake of people and animals alike，the development and acceptance of animal substitutes deserve enthusiastic support．
In some instances, substitutes are already thought as good or better than animals，but supervising agencies（监督机构）have yet to catch up．In both the European Union and the U．S．，scientists and companies wanting to use the new alternative tests complain that regulatory standards for proving a drug or chemical to be safe for humans force the continued use of animals．Thus，animal-loving Americans might turn to persuading the EPA and the FDA to speed validation（确认）of new methods so that they can be more widely employed．And animal advocates（保护者） who want to influence business could consider investing in the small biotech’s and large pharmaceutical（药品的） companies that are working to develop alternatives to animals in research．
【小题1】_____ plays a leading role in replacing the use of animals in testing．
| A．Huntingdon Life Sciences | B．Improvement in technologies |
| C．Animal-fights militants | D．Scientists Alan and Thomas |
| A．animals shouldn’t be used in toxicology testing |
| B．animals should enjoy equal rights with human beings |
| C．animals should live wildly and freely |
| D．we should protect animals from being killed casually |
| A．the use of animals in testing has been stopped abruptly |
| B．animal substitutes are not preferable |
| C．supervising standards contribute to the continued use of animals in testing |
| D．only Huntingdon Life Sciences is accused |
| A．Saving animals and people． |
| B．The new trend in toxicology testing |
| C．The use of animals in testing is against human nature |
| D．New technology changes the fate of animals |
| A．arbitrary（武断的，随意的） | B．pessimistic |
| C．indifferent（不关心的 ） | D．optimistic |

Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour. The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the colour of a dark-striped zebra fish to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebra fish skin colour is determined by pigment cells, which contain melanosomes (黑色素体). The number, size and darkness of melanosomes per pigment cell determines skin colour.
It appears that, like the golden zebra fish, light-skinned Europeans also have a mutation (突变)in the gene for melanosome production. This results in less pigmented skin. However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra fish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun, which can cause skin cancer. But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng. Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin colours, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment done on Michael Jackson.
【小题1】According to the passage, scientists have found .

At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot.
There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can’t fly into the air from the ground. Their wings don’t produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can’t run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight.
During the hours when most enemies are active, bats gather where few animals would think to look and most can’t reach. This allows them to disappear from the world until night comes again. There’s also little competition for these resting spots, as other flying animals don’t have the ability to hang upside down. Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract(紧缩) several muscles in your arm, which are connected to your fingers by tendons(腱)；as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat’s talons(爪) close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn’t have to do anything to hang upside down.
【小题1】Bats hang upside down because________.
| A．they haven’t developed a pair of strong claws |
| B．they can’t start to fly from the ground directly |
| C．they have no hind legs to support their body |
| D．they can’t find quiet places to stay during the day |
| A．is to save their energy for night movement |
| B．is a way to fight against flying animals |
| C．is a great way to hide from danger |
| D．is a skill to compete for the flying places |
| A．Because their upper body is light. |
| B．Because they have strong muscles. |
| C．Because their talons are linked to muscles tightly. |
| D．Because their tendons are linked to their upper body. |
| A．The living habits of bats. |
| B．How and why bats hang upside down. |
| C．The importance of bats’ hanging upside down. |
| D．How bats use their energy at night. |

Below is a selection from a popular science book.
| If blood is red, why are veins (静脉) blue? Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison. Which works harder, your heart or your brain? That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker（超级油轮）. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it. Why do teeth fall out, and why don’t they grow back in grown-ups? Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed（腐烂）and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off. Do old people shrink（收缩）as they age? Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved. Why does spinning make you dizzy)? Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not. Where do feelings and emotions come from? Mostly from an ancient part of the brain called the limbic system（边缘系统）. All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet. If exercise wears you out, how can it be good for you? Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy, it’s more that a lack of exercise leaves your body weak and easily affected by disease. |
| A．Blue | B．Light yellow |
| C．Red | D．Dark reddish purple |
| A．Because their spine is in active use. |
| B．Because they are more easily affected by gravity. |
| C．Because they keep growing backwards. |
| D．Because their spine becomes more bent. |
| A．In the long run, our brain probably works harder than our heart. |
| B．When our brain senses the spinning, we will feel dizzy. |
| C．The brains of the other mammals are as complex as those of humans. |
| D．Our feelings and emotions come from the most developed area in our brain. |
| A．To give advice on how to stay healthy. |
| B．To provide information about our body. |
| C．To challenge new findings in medical research. |
| D．To report the latest discoveries in medical science. |

We know that sugary sodas aren’t good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse.
Americans drink far more sodas than people in other countries— as much as 170 liters per person per year. But the impact of this study isn’t limited to the United States. “Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well,” study author Dr Honglei Chen said in a statement.
The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had.
Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch(鸡尾酒), had a 38 percent higher risk than people who didn’t drink sweetened drinks. And all that extra sugar isn’t the actual problem. Researchers say that the artificial sweetener aspartame may be to blame.
The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results “are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes.”
But there’s a bright side for those who can’t live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn’t drink any coffee, according to the study. “Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk,” said Chen.
【小题1】What has the new study of more than 260,000 people found?
| A．Sugary sodas aren’t good for the physical health of old people. |
| B．Americans have a special tooth for sweet foods. |
| C．Sweetened soft-drinks may increase the risk of depression. |
| D．Sweetened soft-drinks have important physical consequences. |
| A．About twenty-six thousand people participated in it. |
| B．The oldest participants were below 80 when the study was over. |
| C．Most of the participants had depression when the study was over. |
| D．The study lasted more than ten years from the beginning to the end. |
| A．can reduce the harm of sweetened drinks |
| B．is used to reduce the risk of depression |
| C．is mainly used to make fruit punch |
| D．is used to make something .sweet |
| A．more research is needed to confirm the new findings |
| B．the new findings aren’t consistent with any previous findings |
| C．cutting one’s sodas intake will surely reduce one’s depression |
| D．the new findings won’t have an impact on people’s drinking habits |

In recent years，American students have fallen behind in many subjects like math，science and reading. In 2005，the U.S. was number nine among the developed countries in the number of students graduating from high school.
American education officials are searching for new ways to help students learn again. One tool that is getting some attention is the use of video games.
Sixteenyearold John Diaz says he loves playing video games but doesn't like traditional schoolwork. During his summer vacation，Diaz is continuing his studies at home. That is because his courses are available on his home computer.
Florida Virtual School's head master，Julie Young，says the school teaches students with the technology they most enjoy using in and out of school.“We have so many students who feel free in our school，” Young said, “They lose interest when they go to school. And we're very hopeful that Conspiracy Code will attract the learners to really get into the detail of learning.”
Conspiracy Code is a video game that teaches U.S. history. Students guide two heroes in a quest to stop a conspiracy to change the past. Along the way，students learn about events such as the Civil War，and report back to their teacher who is a spy ．
John Diaz says he enjoys American history now.“I like to do the game every day，” he said.
【小题1】In the first paragraph，we can learn that American students________.
| A．do better in science than reading |
| B．do not want to go to college |
| C．have been less interested in studies recently |
| D．do worst in math among the developed countries |
| A．By having an experienced tutor. |
| B．By going to a vacation camp. |
| C．By studying on the computer. |
| D．By watching videos. |
| A．introduces the ways of finding a spy |
| B．teaches students American history |
| C．helps students learn computers |
| D．trains people to become heroes |
| A．Video games becoming new teaching tools. |
| B．How Conspiracy Code helps students study. |
| C．How Florida Virtual School teaches students. |

Global Positioning Systems are now a part of everyday driving in many countries. These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But they can also cause a lot of problems, sending you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two.
Barry Brown is with the Mobile Life Centre in Stockholm, Sweden. The center studies human-computer interaction, or HCI, especially communications involving wireless devices. We spoke to Mr. Brown by Skype. He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay.
Barry Brown: “And they just plugged in an address and then set off to their destination. And, then it wasn’t until they were driving for thirty minutes that they realized they had put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of “garbage in garbage out”. Mr. Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment.
Barry Brown: “One problem with many GPS units is they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it’s going to the wrong place.”
Barry Brown formerly served as a professor with the University of California, San Diego. While there, he worked on a project with Eric Laurier from the University of Edinburgh. The two men studied the effects of GPS devices on driving by placing cameras in people’s cars. They wrote a paper based on their research. It is called “The Normal, Natural Troubles of Driving with GPS.”
Barry Brown: “One of the things that struck us, perhaps the most important thing was that you have to know what you’re doing when you use a GPS. There are these new skills that people have developed. There are these new competencies that you need to have to be able to use a GPS because they sometimes go wrong.” Barry Brown says this goes against a common belief that GPS systems are for passive drivers who lack navigational (导航) skills.
“The Normal, Natural Troubles of Driving with GPS” lists several areas where GPS systems can cause confusion for drivers. These include maps that are outdated, incorrect or difficult to understand. They also include timing issues related to when GPS commands are given.
Barry Brown says to make GPS systems better we need a better understanding of how drivers, passengers and GPS systems work together.
【小题1】What is the best title for this passage?
| A．Is GPS system reliable to use? | B．What is the use of GPS? |
| C．How to make the most of GPS? | D．Blame! GPS or Passengers? |
| A．GPS is just a garbage device. |
| B．GPS will not correct human errors. |
| C．GPS adjusts your wrong destination. |
| D．GPS is just as smart as human beings. |
| A．Small screen. | B．Timing of commands. |
| C．Outdated maps. | D．Dear cameras GPS uses. |
| A．you have to know where to go when using GPS |
| B．you need to have new competencies to use GPS well |
| C．GPS is proper for drivers with little sense of direction |

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed.
There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to eliminate them.
Different products, processes and activities of our industrialized world together form the major source of pollution. The forms of pollution can be mainly divided into three kinds—solid, liquid and gas.
These pollutions have greatly damaged our planet and continue to do so. In fact, pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.
We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the danger of pollution and so on.
The earth is our home and we have the duty to take care of it for ourselves and our later generation. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. Laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.
【小题1】 How many examples of environmental problems are given in the first paragraph?
| A．2 | B．3 | C．4 | D．5 |
| A．In all there are three kinds of pollution |
| B．If people continue to pollute our planet, there will be no trees. |
