1、2020 年職稱英語(yǔ)考試?yán)砉ゎ惸M試題第 7 套：閱讀理解Stress Level Tied to Education LevelPeople 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 1ess-educated people did suffer stress it was more

2、severe and had a larger impact on their health.From this, researchers have concluded that the day-to-day factors that cause stress are n ot ran dom.弋 rllere you ar e insociety determines the kinds of problems that you have each day, and how well you will cope with them.The research team interviewed

3、a national sample of 1.03 1 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 peoplewith college degrees reported stress 44

4、percent of the time.Less advantaged people are less healthy on a dailybasis and are more likely to have downward turns in their health 。” lead researcher Dr.Joseph Grzywacz , of Wake Forest University Baptist Medical Center, said in a prepared statement. “The downward turns in health were connected

5、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 happe

6、ns every day, maybe itsnot seen asa stressor ” Grzywacz says. “ Maybe it is just 1ife.”詞匯： stressful adj. 緊張的 ; 壓力重的 diploma n. 畢業(yè)文憑，畢業(yè)證書(shū) stressor n. 緊張刺激物 devastating adj. 毀滅性的 follow-up n.( 對(duì)病人的 ) 隨訪31. Stress level is closely related toA) family size.B) social status.C) body weight.D) work experi

7、ence.32. The 1.03 1 adults were interviewedA) on adaily basis for 8days.B) during one of eight days.C) all by Grzywacz.D) in groups.33. Which group reported the biggest number of stressful days?A) People without any education.B) People without high school degrees.C) People with high school degrees.D

8、) People with college degrees.34. The less advantaged people are，the greaterA) the impact of stress on their health is.B) the effect of education on their health isC) the level of their education is.D) the degree of their health concern is.35. Less educated people report fewer days of stress possibl

With the flip ( 輕擊) of a switch,30,000homes in one part of Detroit

10、 will soon become the first in the country to receive electricitytransmitted by ice cold high performance cables. Other American cities are expected to followDetroits example in the years ahead, which could conserve enormous amounts of power.The new electrical cables at the Frisbie power station in

11、Detroit are revolutionary becausethey are made of superconductors. A superconductor is a material that transmits electricity withlittle or no resistance. Resistance is the degree to which a substance resists electric current. Allcommon electrical conductors have a certain amount of electrical resist

12、ance. They convert atleast some of the electrical energy passing through them into waste heat. Superconductors dont.No one understands how superconductivity works. It just does.Making superconductors isnt easy. A superconductor material has to be cooled to an extremely low temperature to lose its re

13、sistance. The first superconductors, made more than 50years ago, had to be cooled to -263 degrees Celsius before they lost their resistance. Newersuperconducting materials lose their resistance at -143 degrees Celsius.The superconductors cable installed at the Frisbie station is made of a ceramic ma

14、terial thatcontains copper, oxygen, bismuth （ 鉍 ）, strontium （鍶）, and calcium （ 鈣 ）. Aceramic is ahard, strong compound made from clay or minerals. The superconducting ceramic has beenfashioned into a tape that is wrapped lengthwise around a long tube filled with liquid nitrogen.Liquid nitrogen is s

15、uper cold and lowers the temperature of the ceramic tape to the point where itconveys electricity with zero resistance.The United States loses an enormous amount of electricity each year to resistance. Becausecooled supercondUutors haveno resistance, they waste much less power, other cities arewatch

16、ing the Frisbie experiment in the hope that they might switch to superconducting cable andconserve power, too.What is the benefit of the revolution mentioned in the first paragraph?A. With a flip of swish, electricity can be transmitted.B. Other American cities can benefit from the high- performance

17、 cables.C. Great amounts of power can be conserved.D. Detroit will first receive electricity transmitted by the new electrical cables37、Compared to common electrical conductors, superconductorsA. have little or no electrical resistanceB. Can be used for along timeC. are not energy-efficientD. can be

18、 made easily38、At what temperature does the superconducting ceramic lose its resistance?A. -143 degree Celsius.B. -263 degree Celsius.C. As long as it is ice-cold.D. Absolute zero.39、What element enables the ceramic tape to lower its temperature?A. Copper.B. Liquid nitrogen.C. Clay.D. Calcium.40、Acc

19、ording to the last paragraph, which of the following statements is NOT true?A. Other cities hope they Can also conserve power.B. Other cities hope they Can use superconducting cables soon.C. Superconductors waste less power because of their low resistance.D. The Fribie experiment is not successful.T

20、he Science of the FutureUntil recently, the science of the future was supposed to be electronics and artificialintelligence. Today it seems more and more likely that the next great breakthroughs intechnology will be brought through a combination of those two sciences with organic chemistryand geneti

21、c engineering. This combination is the science of biotechnology.Organic chemistry enables us to produce marvelous synthetic （ 合成的） materials. However,it is still difficult to manufacture anything that has the capacity of wool to conserve heat and alsoto absorb moisture. Nothing that we have been abl

22、e to produce so far comes anywhere near thecombination of strength, lightness and flexibility that we fred in the bodies of ordinary insects.Nevertheless, scientists in the laboratory have already succeeded in growing a material that has many of the characteristics of human skin. The next step may w

23、ell be biotech heartsand eyes which can replace diseased organs in human beings. These will not be rejected by thebody, as is the case with organs from humans.The application of biotechnology to energy production seems even more promising. In1996 the famous science-fiction writer, Arthur C. Clarke,

24、many of whose previous predictionshave come true. He said that we may soon be able to develop remarkably cheap and renewablesources of energy. Some of these power sources will be biological. Clarke and others havewarned us repeatedly that sooner or later we wi/1 have to give up our dependence on non

25、-renewable power sources. Coal, oil and gas are indeed convenient. However, using them alsomeans creating dangerously high levels of pollution. It will be impossible to meet the growingdemand for energy without increasing that pollution to catastrophic （ 災(zāi)難性的 ） levels unlesswe develop power sources

26、that are both cheaper and cleaner.It is attempting to think that biotechnology or some other science of the future can solveour problems. Before we surrender to that temptation we should remember nuclear power.Only a few generations ago it seemed to promise/imit/ess, cheap and safe energy. Today tho

27、sepromises lie buried in a concrete grave in a place called Chernobyl,in the Ukraine.Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerousway.According to the passage, the science of the future is likely to beA. electronicsB. biotechnologyC. genetic engineeringD. nuclear technology42、Organic chemistry helps to produce
