听力原文：The Coast Guard does what its name says; it guards the coasts of the United State
听力原文： The Coast Guard does what its name says; it guards the coasts of the United States. During a war, the Coast Guard becomes part of the United States Navy, and helps to protect against enemy attacks. In times of peace, however, The Coast Guard is part of the United States Department of Transportation. It has responsibility for many different duties. The Coast Guard can be found at many large lakes in America, as well as in coastal waters. It enforces laws controlling navigation, shipping, immigration, and fishing. It enforces other laws that affect the thousands of privately-owned boats in the United States. Coast Guard planes, boats and helicopters search for missing boats and rescue people in dangerous situations. Last year, Coast Guards men saved the lives of almost 7,000 people.
The Coast Guard does scientific research on the ocean. It also uses ice-breaking boats to clear ice from rivers or lakes, so boats can travel safely. One of The Coast Guard's most important duties now is helping to keep illegal drugs out of the United States. Coast Guard boats, armed with guns, use radios and radar to find boats that may be carrying drugs. They stop the boats suspected of carrying drugs and search them, They seize the drugs and arrest the people on the boats. Last year, Coast Guardsman seized more than 800,000 kilo grams of marijuana and cocaine. And-they arrested more than 700 persons trying to bring illegal drugs into the United States.
This kind of action is exiting. Most of the time, however, Coast Guardsman say they see nothing more exciting than the ocean.

Why crime has risen so much further and faster in Britain than in any other rich country over the past half-century is anybody's guess, maybe it's the result of near-American levels of relative poverty and family breakdown combined with a European reluctance to bang up quite such a large proportion of the population as America does. Anyway, the long-term causes are of less immediate interest to the government than a short-term solution. Popular concern about crime is rising: 23% of people rated it as one of the most important issues for the government at the beginning of this year; 34% do now.
An official report concluding that the criminal justice system is failing has added to the government's problems. The Audit Commission, the government's watchdog, says that the police too often charge suspects with the wrong offences, use inaccurate computerized information and face serious inefficiencies in the forensic science (the use of scientific methods by the police) service. Court delays alone are costing taxpayers￡80m ($120m) a year. The result is that few criminals are brought to justice and even fewer convicted. Only 6% of the more than 5m offences recorded by the police last year resulted in a conviction. Hardly surprising, then, that more than half the public believes that the criminal justice system is ineffective.
The main purpose of the White Paper published last year is to address concerns that the procedures of the court are weighted too heavily against the prosecution. It includes many sensible and uncontroversial proposals. It asks for more support for witnesses, many of whom are frightened of testifying. A survey of one London court found that, of 140 witnesses called in a two-week period, only 19 actually turned up.
Making juries more representative must also make sense. Getting off jury service is too easy. In some London courts, two-thirds of those called for jury service fail to turn up. As a result, juries are often composed of housewives, the unemployed and the retired. The White Paper recommends a check on professionals' getting off service, who can excuse themselves by saying their work is too important, and proposes penalties for those who fail to comply.
Other proposed reforms will be more controversial. At present, no defendant can be tried for the same offence twice even if compelling new evidence emerges. The government's plan to scrap that law will be resisted by civil liberties campaigners, as will the proposal that previous convictions should be disclosed in open court if they are relevant to the case being heard.
Whether or not such proposals make it into law, the White Paper did not do much to address public concerns. The reason why 94% of crimes do not result in a conviction is that three-quarters of them are not cleared up, and so nobody is charged. That is the fault of the police, not the courts; and that is the part of the criminal justice system that the government needs to focus on if it is to make a difference.
[A] use insufficient computerized information.
[B] the work of the police, not that of the courts.
[C] a short-term solution rather than the long-term causes.
[D] the mistaken offences.
[E] most of those called for jury duty are absent.
[F] to address public concerns.
[G] who are afraid of appearing in court.
