单选题{{B}}Text 3{{/B}} Some oil companies plan to get rid of some of the pollution they produce by pumping it into rocks deep inside the Earth, where they say it will stay for thousands of years. Other people, though, aren't so sure this is advisable; environmental groups say that putting this pollution back into the Earth is a bad idea. When oil burns, it doesn't just produce heat: it also produces carbon dioxide. Carbon dioxide is a natural part of the air, but because people burn so much oil, there's too much carbon dioxide in the air. This extra carbon dioxide is pollution; some scientific studies show that carbon dioxide is one of the "greenhouse gases 'that is causing the Earth's temperature to rise. Environmentalists say that the oil companies' plans may not work. The oil companies say they are making sure that the gas will never escape, but environmentalists wonder how the oil companies can be so sure that the gas won' t seep into the air. They also point out that there's no way to check to make sure the gas isn't leaking. In addition, the environmentalists point out that the pumping costs money—for research and for equipment—that the oil companies should be spending on preventing pollution, rather than on just moving it someplace else. Another problem, say some people who are concerned about the Earth, is that if the oil companies find a cheap way to get rid of their pollution, they won' t look for new kinds of energy. These environmentalists say that energy companies should be researching ways to use hydrogen, wind power, and solar power instead of finding better ways to use oil. They argue that continuing to use oil means that we will still need to buy oil from other countries instead of producing our own cheap, clean energy. Environmentalists also say that burying pollution just pushes the problem into the future, rather than really solving it. They say that if the oil companies pump carbon dioxide into the rocks inside the Earth, it will be there for thousands of years, and that no one knows if this plan—even if it works—might turn into a pollution problem for all of us in the future. The oil companies insist that their plan is safe, and that putting the gas inside the Earth is a reasonable way to deal with it. They point out that there is a lot of room in the Earth for this extra gas, and that putting carbon dioxide inside the Earth means that the gas won' t be in the air, and if it' s not in the air, it won' t make the Earth warmer.

单选题There is a definite possibility that the climate of the world may be changing. Some scientists imagine that this could even mean the beginning of another ice age. The effects of such a change in climate on the human population of the world would be startling. Recent research suggests that the general warming trend of the past hundred years or so may be coming to an end. During the past ten years, meteorologists tell us the average temperature of the earth has dropped about one degree Fahrenheit. This does not seem like much, but it could have effects on wind and rain patterns which influence the overall weather picture. If these patterns change a lot, it could mean that certain regions of the world may continue to have long droughts while others will possibly suffer from widespread flooding. What regulates the climate is not exactly known. Meteorologists believe that clouds may be an important factor in regulating the amount of solar heat held by the earth, which in turn determines the temperature of the planet. Another possibility is that man' s industrial and agricultural methods may be affecting the natural weather patterns. However, the weather is not understood well enough for scientists to say for certain what is happening to the climate and what side effects this will actually have on the world' s population.
