听力原文： Joe Smith had been brought up in an orphanage: He envied people who were rich and decided that when he grew up he could make a lot of money.
Unfortunately, Joe was not clever and he failed all his school exams. "I will either have to find a good job or I will have to become a thief." Jee said to himself. He know he would never find a well-paid job.
For several months Joe watched a bank out of town. He noticed when it had the fewest customers. He watched, waited and planned.
One afternoon he found that only two tellers were on duty there. "I will either succeed and be Very rich or fail and go to prison." said Joe. He was willing to take the risk.
Then he watched in and pushed a demand. note over the counter. The teller read it, turned pale and quietly opened a small safe behind him. He took out $ 50,000 and placed the bank notes in Joe's open bag. Then Joe ran as fast as he could.
That night Joe had to bury money in case the police caught him. He chose a deserted piece of land near the house, he was glad when the money was safely hidden in the round.
The next day he was woken by bangs on his door. He answered and there came two policemen. "Joe Smith, you are under arrest for robbing a bank !"
Joe protested in vain. The bank had hidden cameras and the whole raid had been photographed. Joe was caught and into prison.
Ten years later Joe was set free. He made sure no one was following him and quickly made his way to the spot where he had buried the money.
Neither happiness nor money waited for him, however. A big building had been built on the site.
By what means did Joe think he could become rich？

SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文： Experts say some farming activities are seriously damaging Earth's environment: Bad farming methods can damage soil, forests and water supplies. They also have caused some plants and animals to disappear.
Two groups now say that bad fanning methods axe threatening the ability of farmers to produce enough food to feed the world population in the future.
The groups used satellite images, maps and modern equipment to study the effect of agriculture on the environment. The study found that the destruction of soil is widespread. Important organic nutrients are being removed from farmland.
Agriculture uses seventy percent of the freshwater in the world each year. The study found that many farmers are wasting water supplies. In addition, chemicals designed to protect crops may pollute waterways.
The report also says as much as thirty percent of the world's forests have been cut down so the land could be used for agriculture. This has led to a severe loss of wildlife and their environments.
Which is not mentioned in the passage as an aspect that farming activities are damaging？
听力原文： American scientists are developing maps that can identify areas of future flooding. The maps also may help scientists estimate the possibility of extremely dry weather and severe storms.
Tom Jackson of the United States Department of Agriculture prepared the map after the April flood. He used information provided by satellites in Earth orbit.
The maps are produced from dish receivers on the satellites. Each dish receiver measures the wetness of the soil by capturing the natural release of microwave radiation from the soil. The receivers turn rapidly. This provides complete coverage of each area the satellite passes over.
Mr. Jackson and other scientists have tested Aqua's equipment in air planes and satellites flying over several states. The scientists used the tests to develop ways to change the information gathered into maps.
Mr. Jackson now plans to compare the microwave dish receiver findings with information from tests on Earth's soil. He will use instruments at Agricultural Research Service centers in four states. He also will study information provided by forty ground observation centers across the country.
Why American scientists are developing these maps？
