It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world.
The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(证明…有罪) murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child.
Jeffrey said he and his colleagues made the discovery by accident while tracking genetic
variations(变异). But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents’ son.·In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man.
DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person’s privacy. That includes a person’s medical history, racial origin or psychological profile. “There is the long-term risk that people can get into these samples and start getting additional information about a person’s paternity(父子关系) or risk of disease,” Jeffrey said.
DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals’ DNA profiles matching in the most commonly used tests at one in a billion.

第三部分：阅读理解（共15小题；每小题2分，满分 30分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
Kenya wants to organize a major international conference to discuss how to fight piracy(海盗) off the coast of Somalia. The conference may also deal with ways to rescue Somalia from seventeen years of civil war. More than forty percent of its people depend on food aid.
Kenyan Foreign Minister Moses Wetangula says the world cannot end piracy and civil war without dealing with Somalia’s political problems.
Somali pirates operate in the Indian Ocean and the Gulf of Aden. The Gulf of Aden connects the Red Sea to the Mediterranean by way of the Suez Canal. The pirates have fast boats, modern weapons and equipment like satellite phones and global positioning systems.
Pirates hijacked the Sirius Star off the coast of Kenya and moved it to waters off Somalia.
The tanker Sirius Star, at three hundred thirty meters long, is the biggest ship ever known to have been captured by pirates. It also happened farther south than most attacks, and farther out at sea ---- more than eight hundred kilometers from land.
The ship was headed for the United States with two million karrels of oil, worth an estimated one hundred million dollars. A Saudi Arabian company owns the tanker. The pirates have reportedly demanded twenty-five million dollars in negotiations to release the ship and its crew of twenty-five.
Somali pirates generally do not steal goods or kill hostages. They are believed to be holding seventeen ships with about three hundred crew members. Among the ships is a Ukrainian vessel hijacked(劫持) in September with a load of military weapons including tanks.
The increase in piracy is raising the cost of insuring ships. Also, oil from the Middle East and exports from East Asia could take longer to arrive.
Some of the world’s heaviest shipping traffic passes the Somali coast. But major shipping companies have begun to consider new routes. One of the world’s biggest shippers, A.P, Moeller Maersk, says it will avoid the Gulf of Aden. A move away from the Suez Canal could hurt Egypt’s economy.
American and other foreign navy ships are now watching for pirates. This week the Indian Navy destroyed a heavily armed “mother ship” in the Gulf of Aden. But the area to protect covers more than one hundred sixty million square kilometers.
56. According to the passage, which of the following is the key to solving the piracy in Somalia?
A. Providing lots of money. B. Ending Civil war.
C. Supplying enough food. D. Handling Somalia’s political problems.
57. Somali pirates do the following things except that _______.
A. they demand moneyB. they hold the ships with crew
C. they kill some of the hostages D. they hijack ships with military weapons
58. What can we infer from the passage?
A. The cost of ship transport is decreasing.
B. The routes of some ships might change.
C. Nothing has been done to fight against the piracy.
D. The Suez Canal is of no importance to Egypt’s economy.

C
Taiwan police cannot decide whether to treat it as an extremely clever act of stealing or an even cleverer cheat（诈骗）.Either way, it could be a perfect crime（犯罪）, because the criminals are birds----homing pigeons.
The crime begins with a telephone message to the owner of a stolen car: if you want the car back, pay some money. Then, the car owner is directed to a park, told where to find a bird cage and how to attach money to the neck of the pigeon inside. Carrying the money in a tiny bag, the pigeon flies off.
There have been at least four such pigeon pick-ups in Changwa. What at first seemed like the work of a clever stay-at-home car thief, however, may in fact be the work of an even lazier and more inventive criminal mind---- one that avoids（避免） not only collecting money but going out to steal the car in the first place. Police officer Chen says that the criminal probably has pulled a double trick: he gets money for things he cannot possibly return. Instead of stealing cars, he lets someone else do it and then waits for the car owner to place an ad in the newspaper asking for help.
The theory is supportd by the fact that, so far,none of the stolen cars have been returned. Also, the amount of money demanded----under 3,000 Taiwanese dollars-----seems too little for a car worth many times more.
Demands for pigeon-delivered money stopped as soon as the press reported the story. And even if they start again, Chen holds little hope of catching the criminal. “We have more important things to do,”he said.
66.After the car owner received a phone call, he ___________.
A. went to a certain pigeon and put some money in the bag it carried
B. gave the money to the thief and had his car back in a park
C. sent some money to the thief by mail
D.told the press about it
67. The “lazier and more inventive”criminal refers to ________.
A.the car thief who stays at home B.one of those who put the ads in the paper
C.one of the policemen in ChangwaD. the owner of the pigeons
68.The writer mentions the fact that “none of the stolen cars have been returned” to show ____________.
A.how easily people get fooled by criminals B.what Chen thinks might be correct.
C. the thief is extremely clever.D.the money paid is too little.
69. The underlined word “they” in the last paragraph refers to ________.
A.criminals B. pigeons C. the stolen cars D.demands for money
70. We may infer from the text that the criminal knows how to reach the car owners because ____________.
A.he reads the ads in the newspaper
B.he lives in the same neighborhood
C.he has seen the car owners in the park
D.he has trained the pigeons to follow them

B
There is an English saying :“laughter is best medicine .”Until recently ,few people took the saying seriously .Now however ,doctors have begun to look into laughter and the effects it has on the human body .They have found that laughter really can improve people’s health .
Tests were carried out to study the effects of laughter on the body .People watched funny films while doctors checked their hearts ,blood pressure ,breathing and muscles .It was found that laughter had similar effects to physical exercise .It increases blood pressure ,the heart beating and breathing ; it also works several groups of muscles in the face ,the stomach ,and even the feet .If laughter exercises the body ,it must be beneficial .
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body .In one experiment doctors produced pain in groups of students who listened to different radio programmes .The group that tolerated(忍耐)the pain for the longest time was the groups which listened to a funny programme .The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain .
As a result of these discoveries ,some doctors in the United States now hold laughter clinics ,in which they help to improve their patients’ condition by encouraging them to laugh .They have found that even if their patients do not really feel like laughing ,making them smile is enough to produce beneficial effects similar to those caused by laughter .
