听力原文： Balloons have been used for sport for about 100 years. There are two kinds of sport balloons: gas and hot air. Hot air balloons are safer than gas balloons, which may catch fire. Hot air balloons are preferred by most balloonists in the United States because of their safety. They are also cheaper and easier to man age than gas balloons. Despite the ease of operating a balloon, pilots must watch the weather carefully. Sport, balloon flights are best early in the morning or late in the afternoon, when the wind is light. Over the years, balloonists have tried unsuccessfully to cross the Atlantic Ocean. It wasn't until 1978 that three American balloonists succeeded. It took them just six days to make their trip from their homes in the United States to Paris, France. Their voyage captured the imagination of the whole world.

(31)

A．Kid's play balloons.

B．Weather balloons.

C．Balloons for safety patrols.

D．Balloons for recreation.

听力原文：When Iraqi troops blew up hundreds of Kuwaiti oil wells at the end of the Gulf Wa

听力原文： When Iraqi troops blew up hundreds of Kuwaiti oil wells at the end of the Gulf War, scientists feared environmental disaster. Would black powder in the smoke from the fires circle the globe and block out the sun？

Many said "No way. Rain would wash the black powder from the atmosphere. But in America, air sampling balloons have detected high concentrations of particles similar to those that were collected in Kuwait. Some oil didn't catch fire. It has formed huge lakes in the Kuwaiti desert. They trap insects and birds, and poison a variety of other desert animals and plants.

The only good news is that the oil lakes have not affected the underground water resources. So far, the oil has not been absorbed because of the hard sand just below the surface.

Nothing, however, stops the oil from evaporating. The resulting poisonous gases are choking nearby residents. Officials are trying to organize a quick cleanup, but they are not sure how to do it. One possibility is to burn the oil. Get those black-powder detectors ready.

The consequence of the Gulf War that has called the concerns of the scientists is ______.

A．The threat of poisonous desert animals and plants.

B．The exhaustion of energy resources.

C．The destruction of oil wells.

D．The spread of the black powder from the rims.
