The deepest oil well enters a mere six miles into the crust (地壳) (the center of the earth is about 4,000 miles deeper). Russian scientists dug the deepest hole in Siberia, but bottomed out at about 7.5 miles below the surface. The Mohole project, a U.S. plan in the 1950s, called for drilling a hole 25 miles down to the boundary between the hard rocks of the crust and the soft mantle (地幔). Sadly the project involved government supporting.
It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust --- about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible.
What little we know about the inside of the earth (like the fact that there"s a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes.
So maybe it"s time for a thorough new method to explore the earth"s inside. Scientist David Stevenson says we should forget about drilling holes. Instead, we should open a crack (裂缝).
Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb. Next, he"d pour a few hundred thousand tons of molten (熔化的) iron into the crack, along with a robot. The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper. The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the surface.
Stevenson compares his idea to space exploration. "We"re going somewhere we haven"t been before,"he says. "In all possibility, there will be surprises.”
This idea can probably be put in the drawer marked with Isn"t Going To Happen. The robot would have to survive temperatures that would melt pretty much anything. But Stevenson"s idea may inspire a new look at an old problem. Great things can come from what seems like impossible ideas.

举一反三
Find art that will allow children to easily make a connection with their lives. Choose the material according to their ages. Pictures and sculptures of children, for example, or dogs and cats are easily understood, and it is easy to start a conversation about how the themes in the art are connected with familiar people and animals in kids’ lives. Music and dance are very important to children and should also be used.
Explore the stories behind famous, and not so famous, art. Encourage children to make up their own stories about paintings and then research the real story behind the paintings.
Create art with children. Teach them that art is not something that they must only observe but something that they can create. Discuss art with children. Encourage them to express their views on art. Let them know that it is okay to dislike something, and listen to their preferences when planning events.
Visit museums and performances. Explore the artwork in local museums that will interest them. Most cities have children’s theaters and music groups, and often free performances are offered. Many art museums have special tours for children.
Through a variety of artistic experiences, kids will learn how to appreciate art and will enjoy it.
64. When choosing art for children, parents should________.

According to research by Dr John Blaine of the University of Southern California, relationships between people whose professions largely depend on their appearances, such as models or actors, tend to end much faster than those between lawyers, doctors or students.
Blaine said the beautiful felt different from childhood. They are treated as special, which may create both arrogance(傲慢) and insecurity. All too often, beauty can be used as an alternative to education. Often they are pushed out of their class or town, told to go off and make their fortune in Hollywood or London and, when the majority fail, they have few talents(才能) to make a living.
Blaine added that beautiful people score poorly on the “big five” — the key factors American experts consider when helping distressed couples. These are neuroticism(神经过敏), including anger and anxiety; extroversion(性格外向); openness to new experiences; agreeableness; and conscientiousness, or sticking by agreements they have made. Attractive people often see no reason to try to change until their looks start to fade.
Krista Sutherland, of the University of California Los Angeles, said partnerships that appeared to be perfect from the outside, such as the former “dream teams” of Nicole Kidman and Tom Cruise or Hugh Grant and Elizabeth Hurley, where backgrounds and aspirations(抱负) are often shared, did not necessarily lead to happiness.
小题1:What does the underlined sentence “Doomed beauties such as Cleopatra and Manilyn Monroe were far from alone in their misery. ” means?
A.Beautiful women always felt lonely. |
B.Beautiful women always were alone. |
C.Many beautiful women didn’t end up with a happy life. |
D.Beautiful women always lived a happy life. |
A.ordinary-looking women | B.women called Jane |
C.common people | D.attractive women |
A.Hugh Grant and Elizabeth Hurley were a couple |
B.Nicole Kidman and Tom Cruise were very satisfied with their life |
C.When they fail in Hollywood, the beautiful have little trouble in making a living |
D.The marriage of the beautiful often last long |
A.Five key factors affecting the partnership | B.Beauties are doomed to fail in love |
C.Beauties or common? | D.The beautiful are different. |
Cubatao, an industrial town of 85 000 people in Brazil, is an example of the connection between industrial development and pollution. In 1954, Cubatao had no industry. Today it has more than twenty large factories, which produce many pollutants(污染物). The people of the town are suffering from the poisonous matter in their environment and the bad effects can be clearly seen. Birth shortcomings are extremely common. Among children and adults, lung problems are sometimes twelve times more common in Cubatao than in other places.
It is true that Brazil, like many other countries, has laws against pollution, but these laws are not enforced strictly enough. It is cheaper for companies to take no notice of the laws and pay the fines(罚款) than to buy the expensive equipment that will reduce the pollution. It is clear, therefore, that economic growth is more important to the government than to the health of the workers. However, the responsibility(责任) does not completely lie with the Brazilian government. The example of Cubatao shows that international companies are not acting in a responsible way either. A number of the factories in the town are owned by large companies from France, Italy, and the U. S. They are doing things in Brazil that they would not be able to do at home. If they caused the same amount of pollution at home, they would be severely(严厉地) punished or even put out of business.
小题1:Why don’t developing countries have strict pollution controls?
A.The new industries they want to introduce do not cause much pollution. |
B.Pollution is not a serious problem for developing countries. |
C.They don’t realize the balance of nature will be destroyed by some pollutants. |
D.If they put stricter controls on industry, fewer companies would build new plants in developing countries. |
A.To show that industry can develop very fast in developing countries. |
B.To show that the pollution problem in Brazil is extremely serious. |
C.To show that industrial growth can cause pollution problems for developing countries. |
D.To show that pollution is killing many people and destroying the whole economy of Brazil. |
A.There are more heart diseases among people who live near chemical factories. |
B.More people suffer from lung diseases because of poisonous matter. |
C.Their health is affected by pollutants the same way as that of other Brazilians. |
D.Babies there are found not as bright as those who live in other places. |
A.The investment(投资) environment in Brazil is suitable for them. |
B.They will not be severely punished if they cause pollution in Brazil. |
C.They can make much money because they do not have to pay Brazilian workers much. |
D.They can act in an irresponsible(不负责任的) way in Brazil because there are no pollution laws there. |
Not very long ago, children were often forced to write with their right hands. Doctors have since found that this can be very harmful. You should use the hand you were born to use.
People who use their left hands are just starting to get better treatment. But why they get all these bad names in the first place? One reason may be that there are not as many left-handed people as there are right-handed people. There is one left-handed person for every five right-handed ones. People who are different are often thought to be wrong. But attitudes do seem to be changing. Fair-minded right-handed people are finally starting to give left-handed people a hand.
小题1:What does the passage lead us to believe when one writes?
A.He can only use his right hand. |
B.He can only use his left hand. |
C.He can use either his left hand or his right hand. |
D.He can use both his left hand and his right hand. |
A.Fair-minded right-handed people want to change the habit of the left-handed people |
B.Fair-minded right-handed people are starting to help the left-handed people |
C.Fair-minded right-handed people are starting to use left hand to write and so on |
D.Fair-minded right-handed people are starting to give up using their left hands |
A.left-handed people have been treated poorly |
B.the number of the left-handed people is larger than that of right-handed people |
C.right-handed people are much cleverer than left-handed people |
D.left-handed people are less smart but hardworking |
A.At one time, left-handed people were forced to use their right hands. |
B.Left-handed people today are being treated better than those in the past. |
C.There are not as many left-handed people as there are right-handed people today. |
D.“Dexterous” comes from Latin, means “evil” and English “sinister” means “handy”. |
A study found that 25% of Australian women would like to keep an office pet. Sue Chaseling of Pet care Information Service said the practice of keeping office pets was good both for the people and the pets.“On the pets’ side,they are not left on their own and won’t feel lonely and unhappy,”she said. A study of major US companies showed that 73% found office pets beneficial(有益的),while 27% experienced a drop in absenteeism(缺勤).
Xarni Riggs has two cats walking around her Global Hair Salon in Paddington.“My customers love them. They are their favorites,”she said.“They are not troublesome. They know when to go and have a sleep in the sun.”
Little black BJ has spent nearly all his two years “working” at Punch Gallery in Balmain. Owner Iain Powell said he had had cats at the gallery for 15 years.“BJ often lies in the shop window and people walking past tap on the glass,”he said.
Ms Chaseling said cats were popular in service industries because they enabled a point of conversation. But she said owners had to make sure both their co-workers and the cats were comfortable.
小题1:The percentage of American companies that are in favor of keeping office pets is ________.
A.73% | B.27% | C.25% | D.15% |
A.works in the Global Hair Salon | B.often greets the passers-by |
