Almost everyone wants to get smarter. We struggle to improve our 36_ , intelligence and attention. We drink cup after cup of coffee to help us 37_ the day.
38 __, a new study published in Current Directions in Psychological Science warns that there are 39___ to how smart humans can get.
Each of our body parts develops in a certain way for a reason. 40 _, we are not 3 meters tall 41 _ most people’s hearts are not strong enough to send 42 _ up that high. Scientists say that our thinking ability works in the same way. A baby’s brain size is limited by a series of __43 , such as the size of the mother’s pelvis (骨盆). If our brains developed to be bigger, there could be more 44 during childbirth.
The study of Jews, who have an average IQ much _ 45_ than other Europeans, showed they were more _46_ to develop diseases of the _47_ system. This might be because of their increased brainpower.
If intelligence cannot be improved, can we at least get better at _ 48 _ ? Not really, say scientists. They studied _49_ like caffeine (咖啡因)that improve attention. They found the drugs only helped people with serious 50 _ problems. For those who did not have trouble paying attention, the drugs could have the 51 _ effect. Scientists say that this suggests there is a(n) 52 limit to how much people can or should concentrate.
Our memory is also a “double-edged sword”. People with extremely good memories could 53__ having a difficult life because they cannot _54 bad things that happen to them.
Thomas Hills, one of the authors of the paper, said that 55 all the problems in trying to get smarter, it’s unlikely that there will ever be a “super mind”.

Water and its importance to human life were the centre of the world’s attention last week. March 22 was World Water Day and 36 the theme “Water for Life”.
There are more than one billion people in the world who live without 37 drinking water. The United Nations 38 to cut this number in half by 2015.
Solving such a big problem seems like a(n) 39 challenge. But everyone, 40 teenagers, can do something to help. A teenage girl in the US has set an example to the 41 of her age around the world.
Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work— 42 discarded(废弃的) batteries（电池）which pollute water.
In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There she saw an exhibit about how 43 in old batteries harm the water of Lake Erie.
Haggerty learnt that 44 the batteries was an easy solution. “I think everybody can do it, because everyone 45 batteries, and it can make a big difference.” With these words, she began to 46 awareness in her area.
She 47 her county government and school board. She got permission to start a recycling programme in schools 48 the public library, hospital, and churches. With help from her family, friends and local waste-management 49 , she gathered containers, arranged transportation, and made a(n) 50 video.
Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programme but had made 51 progress.
When asked 52 she feels like a hero, Haggerty is quite ____53 . “Not really. Well, maybe for the fish I saved!”
Every year the Gloria Barron Prize 54 young Americans aged 8 to 18 who have shown leadership and courage in 55 the public and the planet. Each year ten winners receive US $ 2,000 each, to help with their education costs or their public service work.

People do not analyse every problem they meet. Sometimes they try to remember a solution from the last time they had a 36 problem. They often accept the opinion or ideas of other people. Other times they begin to act without 37 ; they try to find a solution by trial and error. However, when all of these methods 38 , the person with a problem has to start analysing. There are six 39 in analysing a problem.
40 , the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must 41 that there is a problem with his bicycle.
Next the person must 42 the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 43 the parts that are wrong.
Now the person must look for 44 that will make the problem clearer and lead to 45 solutions. For example, suppose Sam 46 that his bike does not work because there is something wrong with the brakes. 47 , he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.
After 48 the problem, the person should have several suggestions for a possible solution. Take Sam as an example 49, his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.
In the end, one 50 seems to be the solution to the problem. Sometimes the 51 idea comes quite 52 because the thinker suddenly sees something in a 53 way. Sam, for example, suddenly sees there is a piece of chewing gum stuck to a brake. He immediately hits on the solution to his problem: he must 54 the brake.
Finally the solution is 55 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem.

Adults are often surprised by how well they remember something they learned as children but have never practised in the meantime. A man who has not had an opportunity to go swimming for years can 1 swim as well as ever when he gets back in the water. He can get on a bicycle after several decades and still 2 away. A mother who has not 3 the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or recite the story of Cinderella or Snow White.
One explanation is the law of over learning, which can be stated as following: 4 we have learned something, additional learning increases the 5 of time we will remember it.
In childhood, we usually continue to practise such skills as swimming, bicycle riding long after we have learned them. We continue to listen to and 6 ourselves of poems such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella or Snow White. We not only learn but __7 .
The law of over learning explains why cramming (突击学习) for an examination, 8 it may result in a passing grade, is not a 9 way to learn a school course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little over learning, 10 , is usually a good investment toward the future.

From this point of view, technology has changed the culture of work. Being reachable might feel like a to those who may not want to be able to be contacted at all times.
I suppose the positive side is that solitude is still possible for anyone who really wants it. Computers can be shut down and mobile phones can be turned off. The ability to be “connected” and “on” has many , as well as disadvantages. Travelers have ended up on mountains, and mobile phones have saved countless lives.

The massive magnitude（震级） 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.
These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake.
Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved.
The quake's epicenter (震中) was in a region of South America that's part of the so-called “ring of fire,” an area of major seismic（地震的） stresses which encircles（环绕，包围） the Pacific Ocean. All along this line, the plates on which the continents move press against each other.
Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal（地壳的）movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP.
Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes.
“We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused.” said Brooks.
What is the main idea of the passage?
A．The earthquake in Chile was dangerous. B．Earthquake often happen in Chile C．The earthquake in Chile moved cities. D．The earthquake in Chile had been predicted.
A．Concepcion B．Buenos Aires C．Santiago D．Valparaiso
A．the fire and the earthquake B．the beautiful places around the ocean C．the plate on which South America lies D．the area around the Pacific Ocean
A．It is under the leadership of Mike Bevis. B．It observes earthquakes worldwide. C．It is designed to watch climate changes. D．It mainly studies the Pacific Ocean.

Most people think of birds as feathered animals that fly. Scientists, 36 , do not define (给…下定义) birds as animals that fly, because some birds do not. Of the 10,000 or so species of birds, 46 cannot 37 . Flight plays a key role in 38 for most birds. It allows them to find food over a 39 area and to get away from enemies. Ancestors of flightless birds may have 40 their ability to fly because they had no regular predators (捕食者) or did not need to fly to find food. Rather than fly, some of these birds developed other 41 to catch food and avoid enemies. Two examples of 42 birds are penguins and ostriches.
43 birds that fly, penguins do not have wide wings or large feathers. In order to catch the fish they feed on, penguins use their powerful wings to swim 44 . And when they swim, they look as if they are flying through the water. The 45 of penguins’ bodies makes it possible for them to dive deep underwater, 46 their thick feathers protect them from the cold.
Ostriches are known for their long legs, long necks, and large size. To 47 themselves, they stay in groups and use their excellent sight and hearing to 48 enemies. As soon as 49 approaches, they can run at a speed of more than 65 kilometers per hour to 50 . In addition to using their strong legs to run, they can kick powerfully.
Not all flightless birds have been 51 in protecting themselves. Flightless birds on some islands had no enemies until people 52 . These birds were hunted and easily caught by people and the animals 53 by people. Human land development has 54 the habitats of some birds.

Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further 1 by industry. If the rapid increase of world 2 continues at the present rate, there may be much greater 3 to human beings. Some scientists 4 of the increase in numbers of people as “population pollution（人口公害）”.
About 2, 000 years ago, the world population was about 250 million. It 5 a billion in 1850. By 1930 the population was two billion. It is now six billion. It is 6 to double by the year 2020. If the population 7 to grow at the same rate, there will be 25 billion people in the 8 a hundred years from now.
Man has been 9 the earth’s resources more and more 10 over the past years. Some of them are almost gone. Now many people believe that man’s 11 problem is how to control the 12 of the population. The material supplies in the world will be far from enough to 13 the human population if the present rate of increase continues.

In 1990 a report was published about what the earth might be like 20 years from then on. The report was a result of a three-year 36 .
According to the report, the picture of the earth in the year 2010 is not a 37 one. The world will be more 38 because the population will continue to grow . The population could be 39 6 300 million, almost 2 115 million more than in 1985 .More people would move into cities, especially cities in 40 countries . Cities like Cairo and Jakarta probably would 41 have 15 million by then .
Food production will 42 , but not enough to feed all the people . Farmers will grow 90% more food than they did in 1985, 43 most of the increase would be in countries that
44 produce enough food for their people . Little increase is 45 in South Asia, Africa and the Middle East . Poor farming ways are 46 large areas of crop land, changing farms into deserts . More farmland is 47 as cities become larger and more houses are built . 48 will get worse as industrial countries burn more coal and oil .Many of the world’s 49 could disappear as more and more trees are cut down . Energy will continue to be a serious problem . The experts say their picture of the earth for the year 2010 50 . They only carried out the situation that 51 today . By changing the situation, by 52 the problems, the picture can be changed . There is 53 time for the nations of the world to work 54 a plan of action . But they warned that 55 too long to make decisions would greatly reduce the chances of success .

It is interesting how NASA(美国航空航天管理局)chose their astronauts for landing them on the moon. They chose men 26 the age of twenty and thirty-five. There were about fifty of them, Many were 27 air pilots. 28 were scientists with two or three degrees. NASA telephoned each man they were going to choose; told him the plans and the 29 they might get in. They then asked him if he was willing to be trained as an astronaut. “How could any man 30 such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous 31 most exciting”
The health and physical condition of 32 was, of course, very necessary. 33 those in very good health and physical condition were chosen.
While being trained to be astronauts. They went through many 34 . They studied the star and the moon, and they also studied geology, the science of rocks. This was necessary 35 astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the 36 of the moon. They were all 37 to fly in helicopters （直升飞机）。These helicopters landed 38 down to give them some experience of the way the spaceship would 39 land on the moon , They were also taught the 40 facts about the conditions in space. They learnt all the technical details of the spaceships and rockets. They visited the scientists and engineers who 41 them. They visited the factories where they were 42. They learnt how every 43 of a space-ship and its instruments work. They also learnt every detail of ground-control 44 .
In a word, to be chosen as an astronaut. One must be in good health, 45 in science and good at piloting.
