Pretoria, South Africa – Hundreds of swimmers play in the water along a South Africa beach. Suddenly a huge shark appears off shore and heads for the bathers. Before it can get close to the swimmers, the shark, for some mysterious reason, starts swimming parallel to the beach. Then it turns away from the shore and heads out to sea, leaving the swimmers untouched.
Such a scene will soon become common along shark-in-fasted (鯊魚成群的) shores. An electrical engineer from the University of Pretoria has developed an electrical system that repels (擊退) sharks by controlling their movements. Confused by this action, the sharks end up turning away from the beach.
In this unusual shark-repellent method, an insulated (絕緣的) cable is buried on the bottom of the sea around a beach where people swim. When an electric current is sent through the cable, an electric field is produced in the water above the cable.
When shark swims into the electric field, nerve cells just below the shark' s skin will sense the field. The electricity produces a reflex (反射作用) action in the shark' s muscles, causing the dangerous animal to swim parallel to the cable. Confused by increasing loss of control of its muscles, the shark suddenly changes its direction and heads seaward, away from the electric field.
In a test of the invisible new shark-repellent system, a cable was placed around a beach in St. Lucia, an island around the beach a long time ago to keep sharks away from swimmers, and a net was left in place during the experiment.
When the electric field was left on for more than a year and a half, no sharks were found in the net. However, when the power was turned off,89 sharks ended up in the net.
Using the electric-wall method instead of net to protect bathers would avoid the needless death of many sharks, said biologists. Currently, thousands of sharks die each year when they become trapped in protective nets that surround holiday resorts in Africa and Australia.  About 10 to 15 humans are killed by sharks annually.
1.Why doesn' t the shark attack the swimmers according to the passage?
A.Because there are so many swimmers in the water.
B.Because the shark isn’t so hungry as to eat the swimmers.
C.Because of some mysterious power from the heaven.
D.Because there is an invisible electric field confusing the shark.
2.An electrical engineer from the University of Pretoria has developed __      .
A.a(chǎn) protective net   
B.a(chǎn) new shark-repellent system
C.the electric field        
D.a(chǎn)n insulated cable
3.An electric field is produced in the water above the cable         .
A.only when a shark swims into the electric field
B.only when an insulated cable is buried on the bottom of the sea around a beach where people swim
C.only when an electric current is sent through the cable
D.only when the sharks are trapped in protective nets
4.Which of the following is NOT TRUE according to the passage?
A.Protective nets had been fixed earlier than the new shark-repellent system.
B.The new shark – repellent system will probably replace the protective nets.
C.Thousands of sharks have died each year since this new system was put into use.
D.Using the electric-wall instead of nets would avoid the needless death of many sharks.

Handwriting reveals a great deal about how an individual thinks, since the brain dictate (發(fā)號(hào)施令) hand movements when a person writes. People who think quickly will write quickly, while people whose thinking is slow will write in the same way. Sometimes we see very elaborate (精致的) handwriting, particularly among public figures, such as actors or politicians, who want to draw attention to themselves. For them, handwriting is like a dress that enables them to stand out from the crowd.
The handwriting of someone who is suited to a routine job will appear well organized, clear, and regular, without any special features drawing attention to it. If the job requires proven accuracy, like that of an accountant(會(huì)計(jì)), the handwriting, especially the numbers, should be precise. On the other hand, someone in sales or public relations must be self-assured, know how to make a good impression, and be able to befriend people even when meeting them for the first time. The handwriting of such individuals will appear rather large, with elaborate capitals and on oversized signature. It will be quick, fluent, and not necessarily reasonable.
Handwriting analysis can be used to find potential behavioral or personality problems. People who are impulsive, aggressive, or dishonest write differently than those who are socially well adapted. Warning signs include broken and strongly or sporadically (零散的) pressured handwriting; disorderly handwriting in which the words run over the lines on the paper, or extremely sharp handwriting. Generally, handwriting that is extreme in any aspect-too small, too weak or too pressured-is suspect.
Evidence of medical problems also shows up in a person’s handwriting. Individuals in pain often stop in the middle of writing. Pauses will be visible in the handwriting of people who experience difficulty breathing, because they stop writing to take a breath.
Handwriting expresses the mental and physical state of the individual, as well. Depressed people write slowly, with lines sloping (傾斜) down and heavy pressure exerted(施加) on the page. People who are excessively excited will write quickly, and their handwriting will be extremely disorganized and practically unreadable. People who are tired tend to write lines that descend down the page, and their handwriting will appear weak and slow. Healthy and vigorous individual will write energetically, and their handwriting will be quick, rhythmic and fluent.
71. The passage is mainly about _____________.
A. what handwriting indicates
B. handwriting and personalities
C. the relationship between handwriting and the individual
D. handwriting analysis and the problems it shows
72. Suppose you are a famous pop star, your handwriting will be in the style of being_______.
A. well-organized          B. oversized           C. elaborate          D. sharp
73. If a person writes with a rather large, elaborate capitals and an oversized signature, we can conclude that he is probably a (an) __________.
A. famous person          B. salesman           C. doctor             D. accountant
74. If you see disorderly handwriting, you will think that the person who writes it is ________.
A. depressed          B. vigorous            C. slow in thinking        D. dishonest
75. According to the passage, a person’s handwriting has something to do with(與……有關(guān)) all of the following EXCEPT his______.
A. mind                B. education          C. health               D. profession (職業(yè))

Experts say that agriculture provides fourteen percent of the world's greenhouse gas emissions each year.The gases released include carbon dioxide, a major cause of global warming.
Twenty-one nations around the world recently joined forces to better understand and prevent greenhouse gas emissions from farms.The Global Research Alliance on Agricultural Greenhouse Gases was launched at the United Nations conference on climate change.The meeting took place in Copenhagen, Denmark last month.
Agricultural experts blame a number of farm activities for producing greenhouse gases.For example, animal waste and cattle digestive systems release methane (甲烷,沼氣) gas.Fertilized soil and the burning of crop waste also release harmful gases into the air.Experts say some methods of farming ?turning the soil to prepare for planting ?also release harmful carbon dioxide.
An official of the European Commission's Directorate General for Research says agricultural greenhouse gas emissions can be cut.Maive Rute suggests feeding animals a diet designed to reduce emissions.
The new agricultural research group says protecting against global warming is only part of its purpose.It says the world also needs to develop better farming methods to feed growing populations in poor countries.
United States Agriculture Secretary Tom Vilsack said no one single nation can fight agricultural greenhouse gas emissions and increase food production at the same time.This is why the alliance is important for combining resources and finding new ones.
The United States Department of Agriculture will increase spending on farm emissions research by ninety million dollars over the next four years.The total will reach one hundred thirty million dollars.The U.S.D.A.will share the research with other countries in the Global Research Alliance on Agricultural Greenhouse Gases and support researchers from developing countries that belong to the alliance.Money from the Borlaug Fellowship program will let the researchers study agricultural climate change with American scientists.
Mister Vilsack said that just as climate change has no borders, there should be no borders for research.
72.In Paragraph 4, Maive Rute recommends _____.
A.increasing food production
B.changing cattle digestive systems
C.developing better fanning methods
D.giving animals the food meant to produce fewer emissions

Many people say that the United States is a paradise for the children, a struggling field for the youth and a tomb for the aged. However, the situation is quite different in Australia. Different people have their own ways for enjoyment and their own worlds of pastime.
Most children often work hard in school since they have to face various exams. After school they do not want to confine themselves to books any more. Instead, they put aside their schoolbags at home and sneak quickly to some quiet street comers for their games. Bigger children like to shoulder their large kites to some steep cliffs, and jump to fly in the sky with their kites.
Some old people often get up early in the morning and go to parks to do newspaper reading. After breakfast, they come to horse races, dog races and sometimes car races for betting. If he wins, he will feed himself a good dinner. In the evening, they stay at home, watching TV sometimes with grandchildren. Some of the aged also enjoy fishing and gardening.
Young people prefer to go outing for holidays. At the weekends, they go to the seashore for swimming or to the forest for hunting and camping, or mountainous areas for picnicking. Then in the evenings on Sundays, they start their long bumper-to-bumper drive back on the highways. Nobody seems in a hurry.
The Australian government also encourages its people to have more relaxation after work. Sometimes, certain kind of financial help is distributed to people going on holidays and public holidays are purposely set on Monday or Friday so that Australians may have a longer weekend for enjoyment. They think people can word better only after they get a full relaxation. And it grows out of this idea that relaxation comes the top priority(優(yōu)先權(quán))for enjoyment in Australia.
60.According to many people’s opinion, which of the following is NOT true?
A.All people in the US live a desirable life.
B.The competition among American young people is fierce.
