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. (33) A．Guarding the coasts of the United States.
