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.

The United Nations published a report that was called "The State of World Population". It shows that the growth rate of world population. will actually go down in the next ten years. The growth rate will fall from the present 1.8% to a rate of about 1.6% by the end of this century. But the report also points out that problems of food, health care, housing care, housing, jobs and schools will get worse unless we do something about the situation.
Why is this? Although the total growth rate of the world population will decrease(下降), in some countries there will be a big rise in the population. More people will be born in Third World countries than in the richer Northern countries. So the population will grow faster in poor countries; and the problems in these countries will be very serious. This is because the family is more likely to survive(幸存) if there are a lot of children to work for the members who become old or who cannot find work. A survey of the UN also shows that the growth rate is low where there is a higher level of income, better education, more health care and better living conditions. In this aspect, government plays an important role. So, the conclusion of the UN report is: "Look after the people and the population will look after itself."
What can we learn about the growth rate of population?
A.The total growth rate of world population will increase.
B.The growth rate of population in richer countries will increase.
C.The growth rate of population in poor countries will increase.
D.The total growth rate in American countries will increase.

1 In 1959 Americans welcomed Alaska into the Union as the 49th state, symbolizing a change of attitude from that held in 1867, when the peninsula was purchased from Russia. Then, most Americans had little interest in 1,500,000 square kilometers "of icebergs and polar bears" - beyond Canada's western borders, far from the settled areas of the United States.
2 In those sections of the state which lie above the Arctic Circle, Alaska still is a land of icebergs and polar bears. Ice masses lie buried in the earth, which is permanently frozen to a depth of 90 or more meters. From early May until early August, the midnight sun never sets on this flat, treeless region, but the sun cannot melt the icy soil more than two - thirds of a meter down.
3 Alaska is America's largest state, but only about 325,000 people live there. According to estimates, 800,000 hectares of its land area are fit for plowing but only about 640,000 hectares are being cultivated.
4 Arctic Alaska has been the home of Eskimos for countless centuries. It is believed that the Eskimos moved there from Mongolia or Siberia, probably crossing Bering Strait, named for Vitus Bering, the Danish sea captain who discovered Alaska on his voyage for Russia in 1741. The Eskimos are the state's earliest known inhabitants5. Russian fur traders established settlements but, by the time Alaska was sold to the United States, most of the traders had departed.
5 In 1896 gold was discovered near the Klondike River in Canada just across the Alaskan border. Thousands of Americans rushed to the region on their way to Klondike; some never returned. Alaska was never completely cut off again, although even today transportation is a major problem. There are only two motor routes from the US mainland, and within the state, every town has its own airfield. Planes fly passengers, mail and freight to the most distant villages.
6 The gold that changed life so suddenly for Alaska was soon ended, and although many stories about mining camps have become part of American literature, the gold from Alaskan earth contributed less to economic progress than the fish from Alaskan waters. The fish caught in a single year range in value from $80 million to $90 million. Fur-bearing animals are plentiful in the forests and streams, and valuable fur seals inhabit the waters. After fishing, the state's chief industry is lumber and the production of wood pulp. In recent years, Alaska's single most important resource has become oil. The state also has large deposits of coal, copper, gold and other minerals.
