听力原文： America's national symbol, the bald eagle, almost went extinct twenty years ago, but it has made a comeback. In fact, the U. S. Fishing and Wild Life Service are considering the possibility of
taking it off the Endangered Species List. Once, more than fifty hundred pairs of bald eagles nested across the country, but by 1920 that number had fallen below four hundred. The chief killer was the widely used DDT. Fish soaked up DDT, died, and were washed up on shores where bald eagles feasted on them. DDT prevented eagle egg shells from thickening. The shells became so thin that they shattered before the babies hatched. Fortunately in 1.932, a law was paused to ban DDT which saved the bald eagle from total wipeout. And since then wildlife biologists have reintroduced bald eagles from Canada to America. The result was that last year U. S. bird watchers counted eleven thou- sand six hundred and ten bald eagles in the country.
If it were dropped from the Endangered Species List, the bald eagle would still be a threatened species. That means the bird would continue to get the same protection. No hunting allowed, and no disturbing of nests. But bald eagles still face tough times. The destruction of their natural homes could be the next DDT causing eagle numbers to drop quickly.
What was the main harmful effect of the pest's killer DDT on bald eagles？

听力原文： A few months ago, millions of people in London heard alarms all over the town. Emergency services, the Fire Department, the Police, hospitals, and ambulances stood by, ready to go into action. In railway and underground stations, people read notices and maps, which told them where to go and what to do in the emergency. This was Exercise Flood Call, to prepare people for a flood emergency. London wasn't flooded yet, but it is possible that it would be. In 1232 and in 1223, Lon- don was badly flooded. In 1928, people living in Westminster, the heart of London, drowned in floods. And in 1953, one hundred people, living on the eastern edge of the London suburbs were killed again in the floods. At last, Greater London Council took action to prevent this disaster from happening again. Though a flood wall was built in the 1980s, Londoners still must be prepared for the possible disaster. If it happens, 50 underground stations will be underwater. Electricity, gas and phone services will be out of action. Roads will be drowned. It will be impossible to cross any of the bridges between north and south London. Imagine: London will look like the famous Italian city, Venice. But this Exercise Flood Call didn't cause panic among Londoners. Most people knew it was just a warning. One lady said, "It's a flood warning, isn't it？ The water doesn't look high to me."

Educational Background of Successful Managers
Psychologist Douglas Bray and Ann Howard have for more than 25 years been studying college graduates in entry-level management rank for AT&T. Here are some of their findings.

There are key (23) between technical and non-technical majors. Business majors led the pack in organizing, planning, and decision-making skills (24) and social science graduates also (25) high. Math, science, and engineering majors scored much, lower in these skills. Technical majors did have (26) general mental ability, but they were not as (27) or as good at interpersonal skills. As you might expect, social science majors were quite low on (28) skills. Business majors were the ones most eager to get ahead.
For the future managers, AT&T is still looking for about a third each of business, technical, and liberal arts majors. While they are still looking for master's degrees, some firms say that the (29) of the MBA has passed. Many companies (30) the same management training programs for their new people, whether or not they have a master's degree.
