With his leg lame and his teeth uneven, a boy thought of himself as the most unfortunate child in the world. He seldom played with his classmates, and when asked to answer questions, he always his head without a word.
One spring, his father brought home some saplings (树苗). of his children would plant a sapling and he promised, “Whoever grows his sapling best shall get a gift.” The boy certainly wanted to get the gift.But seeing his brothers and sisters watering the trees, he an idea: he hoped the tree he planted would die soon. So watering it once or twice, he never it.
Several days later, he was surprised to find it didn't die, but grew so many fresh . Compared with those of his brothers and sisters, his appeared greener. His father kept his ，bought the boy a gift and said he would become an outstanding after growing up.

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.
The new science of spending comes to a surprising conclusion .How we use our money may as much or more than how much we’ve got it.
Money spent on experiences , rather than material goods, more happiness.
Imagine that you wake up tomorrow morning to $1 million under your bed .What would you do that cash?
The money will probably make you think about one thing all else---- yourself. A large amount of research reveals that money our selfish sides. We will much on what that money can do for us alone. Perhaps you are imagining buying a faster car, or even a new house.
But studies show that goods often fail to deliver happiness. Fortunately ,our ongoing research many ways to get more happiness from every dollar you spend .Changing how you spend money can increase your happiness.
But making these needs to challenge some of our ideas of spending. It’s hard not to buying a house as a wise investment. But research shows it brings very little happiness. A study in the United States found that homeowners , on average ,were no happier than .
So, working hard to save money for a house might not be such a good idea it means spending less time with your families and friends.
And dozens of studies show that people get more happiness from buying than material things. Experimental purchases—such as trips ,concerts and special meals –are more connected to our sense of self.
And experiences come with one more . They tend to bring us to other people , but more often, material things are enjoyed .So social contacts are important to mental and physical health.

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. A number of flightless birds 55 because they were unable to adapt to new conditions and new enemies.

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. There is already over-crowding（过分拥挤）in many cities and 14 in some countries. Many people believe that human survival（生存） in the future 15 on the answer to the question.

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 .

Do fight against painting pollution
Do you know what kind of things the young people are reading? More and more and teachers have noticed another kind of pollution, which comes from the printed papers on streets.
These printed things newspapers but have hardly anything to do with . You can only find reading materials badly made up there-some are too strange for anyone to ; others are frightening stories of something . However, many of the young readers are getting interested in such reading, which them what they should pay for their breakfast and brings them nightmares and immoral ideas in . Homework is left and daily games lost.
These sellers stand about on streets selling their papers well. The writers, publishers and printers, they are, we never know, are their silent money.
The sheep-skinned wolf’s story seems to have been forgotten once again. Why not this kind of thing? Yes, both teachers and parents have asked each other for more strict control of the young readers. , the more you want to forbid it, the more they want to have a look at it. you may even find several children, driven by their curious natures, one patched paper, which has traveled from hand to hand.
It really does to our society. It has already formed a sort of moral pollution. The teachers and parents need more powerful support in their protection of the young generation. At the same time, the young need more interesting books to help them those ugly paper.

What would you think if someone suggested knocking down St Paul’s Cathedral to widen the road? Or pulling down Big Ben to make way for a car park? It would be ridiculous, right? But when it comes to devastation (毁灭) of the natural world, we aren’t so easily shocked. But we should be…or we’ll be in a lot of trouble.
Nature is shrinking by the day. Ancient forests are destroyed. Wetlands are becoming dry. Woodland is disappearing, and all in the name of progress. This is bad in itself, but it’s devastating for biodiversity.
Biodiversity refers to the variety of plants, animals and other living things that are all interconnected. The ecological services provided by biodiversity are vital to everyday life. The air we breathe is a product of photosynthesis (光合作用) by green plants. Insects, worms and bacteria break down waste and make soils rich. And tiny organisms clean the water in rivers and sea. In fact, all life on the earth exists thanks to the benefits of biodiversity. More than 90 percent of the calories consumed by people worldwide are produced from 80 plant species. And 30 percent of medicines are developed from plants and animals. Maintaining a wide diversity of species in each ecosystem is necessary to preserve all living things.
The loss of biodiversity could be devastating. “It is wrong to think that biodiversity can be reduced indefinitely without threatening humans,” said Harvard University biologist Edward O. Wilson, known as the “father of biodiversity”. He warned, “We are about to reach a critical point beyond which biodiversity loss will become irreversible (不可挽回的).”
But what can we do? The present problem is that the concept of biodiversity is so vague (含糊的). People might care about giant pandas, but it is much harder to excite them about the fate of tiny sea creatures which are being boiled to death in the cooling systems of power stations along coastlines. The Guardian newspaper is trying to help.
