第二篇 Stress Level Tied to Education Level People with less education suffer fewer stressful days, according to a report in the current issue of the Journal of Health and Social Behavior. However, the study also found that when less-educated people did suffer stress it was more severe and had a larger impact on their health. From this, researchers have concluded that the day-to-day factors that cause stress are not random. Where you are in society determines the kinds of problems that you have each day, and howwell you will cope with them. The research team interviewed a national sample of 1,031 adults daily for eight days about their stress level and health. People without a high school diploma reported stress on 30 percent of the study days, people with a high school degree reported stress 38 percent of the time, and people with college degrees reported stress 44 percent of the time. "Less advantaged people are less healthy on a daily basis and are more likely to have downward tums in their health." lead researcher Dr. Joseph Grzywacz,of Wake Forest University Baptist Medical Center, said in a prepared statement. "The downward tums in health were connected with daily stressors. and the effect of daily stressors on their health is much more devastating for the less advantaged." Grzywacz suggested follow-up research to determine why less-educated people report fewer days of stress when it is known their stress is more acute and chronic. "If something happens every day, maybe it’s not seen as a stressor" Grzywacz says. "Maybe it is just life." stressor n.紧张刺激物 devastating adj.毁灭性的 follow-up n. (对病人的)随访 Less-educated people report fewer days of stress possibly because ______.
A. they don’t want to tell the troth
B. they don’t want to face the truth
C. stress is too common a factor in their life
D. their stress is more acute

Directions:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written neatly on ANSWER SHEET 2.All U. S. nuclear weapons production facilities are presently closed down, and if the various agreements are adhered to, those facilities will never be required except for one critical capability. All modern nuclear weapons use uranium (铀), plutonium (钚), and tritium (氚). Uranium and plutonium have very long half-lives, and there is large surplus of these materials.Tritium, however, has a relatively short half-life of about 12.6 years, so about 5 percent of the amount on hand must be replaced each year to maintain the current inventory. (46) Because of the large retirement of nuclear weapons by the United States in compliance with early agreements and national policy, tritium from retired weapons has been used to make up that lost through natural decay. (47) However, in about 10 to 15 years, depending on future negotiations, the United States will need a guaranteed supply of tritium to maintain its stockpile at whatever level is agreed on.In anticipation of this future need to produce tritium, Defense Office Executive is pursuing two technologies. One uses a nuclear reactor that could also produce electricity whose sale would recover not only the capital cost of the reactor but also its annual operational cost. (48) Unfortunately, the present Administration has a definite bias against nuclear power, so an alternative method is also being pursued even though it is agreed that it will cost twice as much as a reactor and use as much electricity as a reactor would produce. This technology uses an accelerator to produce high-energy protons that in turn produce neutrons.The main argument for the accelerator is that it produces no conventional nuclear wastes. (49) Proponents readily admit that it will produce radioactive materials, but with a relatively short half-life compared with that of wastes from spent nuclear fuel. The fact that the accelerator will require the equivalent of a nuclear power plant to supply its electricity is ignored.(50) Proponents ’also neglect to mention that about 22 percent of all electrical energy generated in the United States comes from nuclear power plants, so that 22 percent of the power used by the accelerator will generate conventional nuclear wastes, in addition to those the accelerator produces. There is an alternative to either the reactor or the accelerator, which is simply to buy the required tritium from Canada or Russia. Proponents readily admit that it will produce radioactive materials, but with a relatively short half-life compared with that of wastes from spent nuclear fuel
The molecules of carbon dioxide in the Earth’s atmosphere affect the heat balance of the Earth by acting as a one-way screen. (1) these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concerned, to pass (2) , they absorb some of the longer-wave-length, infrared emissions radiated from the Earth’s surface, radiation that would (3) be transmitted back into space. For the Earth to maintain a constant average temperature, such emissions from the planet must (4) incoming solar radiation. If there were no carbon dioxide in the atmosphere, heat would (5) from the Earth much more easily.Today, (6) , the potential problem is too much carbon dioxide. Could the increase in carbon dioxide (7) a global rise in average temperature, and could such a rise have serious (8) for human society Mathematical models that allow us to calculate the rise in temperature as a function of the increase (9) ;that the (10) is probably yes.One mathematical model (11) that doubling the atmospheric carbon dioxide would raise the global mean surface temperature by 2.5℃. This model assumes that the atmosphere’s relative humidity remains constant and the temperature decreases with altitude at a (12) of 6.5℃ per kilometer. The assumption of constant relative humidity is important, because water vapor in the atmosphere is another (13) absorber or radiation at infrared wavelengths. Because warm air can hold more (14) than cool air, the relative humidity will be constant (15) the amount of water vapor in the atmosphere increases (16) the temperature rises. (17) , more infrared radiation would be absorbed and reradiated (18) to the Earth’s surface. The resultant warming at the surface could be expected to melt snow and ice, (19) the Earth’s reflectivity. More solar radiation would be absorbed, (20) to a further increase in temperature.
