Those helping one unit within a parent pany won’t necessarily help other units. Section C Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need. A. Many alternatives have been suggested to the nuclear waste storage. B. Why do many people worry about the risk of global warming? C. What if it leaks into the ground and reaches human water supplies? D. To store even part of the present nuclear waste requires a vast area. E. The problem of nuclear waste seems totally hard to deal with. F. To dispose it into the remote regions which are less populated. As people recognize the dangers of fossil fuel plants, especially the risk of global warming from carbon dioxide production— nuclear power begins to look more attractive. But what about the waste— all that highly radioactive debris(殘核 ) that will endure for thousands of years? Nuclear waste is one of the biggest technical issues that any future president is likely to (钚 ) has a halflife of 24,000 years. Even after 100,000 years, the radiation will still be above 10% of the level it had when it left the can we possibly prove that this material can be kept safe for 100000 years? Still the US government persists in pursuing “safe”nuclear waste disposal( 處理 ). It has created nuclear waste facilities buried deep within Yucca Mountain , Nevada. To keep the waste safe, the storage rooms are 1,000feet below the surface. _______69__________. It needs at least 2 square miles. The cost of the facility is expected to reach $100 billion ,with hundreds of billions of dollars more in operating costs. To make matters worse, earthquakes happen often in the Yucca Mountain region. More than 600 earthquakes of magnitude of and higher have occurred within 50 miles in the last decade alone. Although that was millions of years ago, how sure can we be that the waste facility won’t be torn apart by another eruption? ________70_________ Why not just send the waste into the sun? Well, maybe that’s not such a good idea, since on launch some rockets do crash back down to the earth. Some scientists have proposed that the waste be put in ships and sunk under the oceans. Yet just the fact that scientists make such suggestions seems to emphasize how the problem really is. IV. Summary Writing Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible. To airline and airport operators, fog is an enemy. When the white, misty blanket hides runways, airplanes cannot take off or land. Changes in flight schedules cost the airlines several million dollars each year. Fog is an concentration of tiny water droplets suspended in the air. It most often occurs when warm, most air is suddenly cooled. To clear the air of fog, it is necessary to evaporate the droplets or cause them to join together and fall as rain or snow. In 1968, a new fogsweeping machine was tested for dissipating(驅(qū)散） the most mon king of fog, which occurs at temperature above freezing. The machine consists of 100footlong plastic tube mounted on a mobile blower. As the machine moved across the airport, chemicals were blown through the tube and up into the fog. One of the chemicals reduces the surface tension on the water droplets so that they would join together more easily. Another chemical gave an electronic charge to the droplets, so that they attracted each other and fell as rain. Cold fog, which occurs at temperatures below freezing, causes only a small percentage of airport shutdowns. Cold fog is fairly easy to eliminate. For quite a few years, airports have used cloudseeding methods to dissipate cold fog. An airplane drops crystals of dry ice into the fog. Soon, snow falls and the air clears. In the 1900s, another kind of weapon against fog was developed. Pilots who are flying through fog fire a pulse of laser light toward the runway. The light that would normally be reflected by the fog is screened out by a sensor. When the laser pulse returns, the sensor opens briefly to admit only the light reflected from the runway, thus enabling the laser to “see” the runway through the fog. These new “whether weapons” are helping to win the war against fog. 第 II卷 （共 40分） V.
