单选题Have you ever gone to a concert and realized that your seats were right next to the booming speakers? Are you guilty 1 turning up the volume on your portable cassette or CD player to drown out the whining of your little brother? Sometimes it"s difficult to avoid loud music or noises, but they can be bad news because loud noises can 2 temporary or permanent hearing loss. Extremely loud music and noises that go on for long periods of time are common causes of deafness. If a noise is so loud that you have to shout to make yourself 3 , there is a 4 that the mechanism inside your ear can be injured. Temporary heating loss can happen after you"ve been exposed to loud noise for only 15 minutes. If you have temporary hearing loss, you won"t be able to hear as 5 as you normally can, and you may have tinnitus, which is a fancy word for ringing in the ears. Your ears call feel "full", too. 6 , these things usually go away and your heating soon return to normal. Permanent hearing loss can happen when someone is exposed to loud noise over and over. Construction workers and people who work in factories must 7 ear protectors because the equipment they use can be extremely loud. But even some lawn mowers and power tools can permanently 8 a person"s ability to hear high-pitched noises and can also give him permanent tinnitus. Listening to extremely loud music over and over can also have the same effect on a person"s hearing. And using headphones on a portable cassette or CD player can be dangerous 9 if the volume is too high and the headphones are used a lot, the noise can damage the ears. The best way to avoid hearing loss is to wear ear protectors when working with machinery and earplugs when going to a concert. Headphones are OK to wear when you"re listening to music; just be sure the volume isn"t too high, and give them a rest 10 once in a while.

单选题{{B}}Passage 3{{/B}} In their world of darkness, it would seem likely that some of the animals might have become blind, as has happened to some cave fauna. So, indeed, many of them have, compensating for the lack of eyes with marvelously developed feelers and long, slender fins and processes with which they grope their way, like so many blind men with canes, their whole knowledge of friends, enemies, or food coming to them through the sense of touch. The last traces of plant life are left behind in the thin upper layer of water for no plant can live below about 600 feet even in very clear water, and few find enough sunlight for their food-manufacturing activities below 200 feet. Since no animal can make its own food, the creatures of the deeper waters live a strange, almost parasitic existence of utter dependence on the upper layers. These hungry carnivores prey fiercely and relentlessly upon each other, yet the whole community is ultimately dependent upon the slow rain of descending food particles from above. The components of this never-ending rain are the dead and dying plants and animals from the surface, or from one of the intermediate layers. For each of the horizontal zones or communities of the sea that lie between the surface and the sea bottom, the food supply is different and in general poorer than for the layer above. Pressure, darkness, and silence are the conditions of life in the deep sea. But we know now that the conception of the sea as a silent place is wholly false. Wide experience with hydrophones and other listening devices for the detection of submarines has proved that, around the shore lines of much of the world, there is the extraordinary uproar produced by fishes, shrimps, porpoises and probably other forms not yet identified. There has been little investigation as yet of sound in the deep, offshore areas, but when the crew of the Atlantis lowered a hydrophone into deep water off Bermuda, they recorded strange mewing sounds, shrieks, and ghostly moans, the sources of which have not been traced. But fish of shallower zones have been captured and confined in aquaria, where their voices have been recorded for comparison with sounds heard at sea, and in many cases satisfactory identification can be made. During the Second World War the hydrophone network set up by the United States Navy to protect the entrance to Chesapeake Bay was temporarily made useless when, in the spring of 1942, the speakers at the surface began to give forth, every evening, a sound described as being like "a pneumatic drill tearing up pavement". The extraneous noises that came over the hydrophones completely masked the sounds of the passage of ships. Eventually it was discovered that the sounds were the voices of fish known as croakers, which in the spring move into Chesapeake Bay from the offshore wintering grounds. As soon as the noise had been identified and analyzed, it was possible to screen it out with an electric filter, so that once more only the sounds of ships came thorugh the speakers.

单选题2 Climatic conditions are delicately adjusted to the composition of the Earth's atmos phere. If there were a change in the atmosphere—for example, in the relative proportions of atmosphere gases—the climate would probably change also. A slight increase in water vapor, for instance, would increase the hem-retaining capacity of the atmosphere and would lead to a rise in global temperatures. In contrast, a large increase in water vapor would increase the thickness and extent of the cloud layer, reducing the mount of solar en ergy reaching the Earth'surface. The level of carbon dioxide, CO2 in the atmosphere has important effect on climatic change. Most of the Earth's incoming energy is short-wavelength radiation, which tends to pass through atmospheric CO2 easily. The Earth, however, reradiates much of the re ceived energy as a long-wavelength radiation, which CO2 absorbs and then remits toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by the Ve- nus, a planet covered by heavy clouds composed mostly of CO2, whose surface tempera tures have been measured at 43℃. If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2 concentra tion were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the CO2 concentration would lead only to a reduction in global temperatures of 3℃. If, because of an increase in forest fires or volcanic activity, the CO2 content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relies on both the warmth and the availability of CO2, would probably increase. As a consequence, plants would use more and more CO2,Eventually CO2 levels would diminish and the cli mate, in turn, would become cooler. With reduced temperatures many plants would die; CO2 would thereby be returned to the atmosphere and gradually the temperatures would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2 present in the atmosphere, with regular temperature increase and decrease of a set magnitude. Some climatologists argue that the burning of fossil fuels has raised the level of CO2 in the atmosphere and has caused a global temperature rise of at least 1℃. But a supposed global temperature rise of 1℃ may in reality be only several regional temperature increase, restricted to areas where there are many meteorological stations and caused simply by shifts in the pattern of atmospheric circulation. Other areas, for example the Southern Hemi sphere oceanic zone, may be experiencing an equivalent temperature decrease that is unrec ognized because of the shortage of meteorological recording stations.
