1、2021职称英语考试真题卷（3）本卷共分为1大题50小题，作答时间为180分钟，总分100分，60分及格。一、单项选择题（共50题，每题2分。每题的备选项中，只有一个最符合题意） 1.第二篇： Around 45% of the UKs carbon dioxide emissions come from the energy people use every-at home and when they travel . In order to generate that energy, fossil fuels (coal oil, and gas) are burnt, and these
2、 produce greenhouse gases- in particular carbon dioxide (CO2) a year, and it is the same CO2 that is changing the climate and damaging the environment. CO2 and various other gases wrap the earth in an invisible blanket helping to prevent heat from escaping. Without this greenhouse effect, the averag
3、e temperature on Earth would be around -18, compared with the current average of around +15. The composition of this blanket of gases has remained relatively constant for many thousands of years. However, since the industrial revolution began around 200 years ago, people have been burning increasing
4、 amounts of fossil fuels, thus releasing more CO2 and other greenhouse gases in the process. This has increased the heating effect of the blanket, trapping more of the suns energy inside the Earths atmosphere in turn the Earths temperature has increased more rapidly in a shorter pennd of there that
5、it has for thousands of years.In 2008, the total UK CO2 emissions were 533 million tones 27% (144 million tonnes ) of those emissions came from the energy used to heat, light, and power homes. Transport emissions caused by passenger cars, buses and motorcycles accounted for a further 16% (87 million
6、 tonnes ) of the UKs CO2 emissions. These figures show that a significant amount of CO2 results from ordinary citizens carbon footprint in their daily activities and lifestyle.The effects of climate change can be seen all around us. Weather patterns are cecoming more and more fractured and uncertain
7、, and over the last century trends in warm weather have become increasingly common. In the UK in the last 40 years, winters have grown warmer with much heavier rainfall. One of the clearest shifts over the last 200 years is towards summers that are hotter and drier, causing pervasive water shortages
8、. Recent years have been the hottest since records began and during August 2003 the hottest outdoor temperature in the UK was recorded -38.5.What is the authors opinion about the level of CO2 emissions in the UKAThe majority of CO2 emissions come from motorized transport.BCO2 emissions may cause cli
9、mate change in the futureCMore CO2 emissions come from homes than from carsDThe average citizen does not create much CO2 2.第三篇：First Sell-contained Heart ImplantedA patient on the brink of death has received the worlds first self-contained artificial hearta battery-powered device about the size of a
10、 softball that runs without the need for wires, tubes or hoses sticking out of the chest.Two surgeons from the University of Louisville implanted the titanium and plastic pump during a sever-hour operation at Jewish Hospital Monday. The hospital said the patient was “awake and responsive” Tuesday an
11、d resting comfortably. It refused to release personal details.The patient had been expected to die within a month without the operation, and doctors said they expected the artificial heart to extend the persons life by only a month. But the device is considered a major step toward improving the pati
12、ents quality of life.The new pump, called AbioCor, is also a technological leap from the mechanical hearts used in the 1980s, which were attached by wires and tubes to bulky machinery outside the body. The most famous of those, the Jarvic-7, used air as a pumping device and was attached to an appara
13、tus about the size of a washing machine.“I think its potentially a major step forward in the artificial heart development,” said Dr. David Faxon, president of the American heart Association. However, he said the dream of an implantable, permanent artificial heart is not yet a reality: “This is obvio
14、usly an experimental device whose long-term success has to be demonstrated.”Only about half of the 4,200 Americans on a waiting list for donor hearts received them last year, and most of the rest died. Some doctors, including Robert Higgins, chairman of cardiology at the Medical College of Virginia
15、in Richmond, said artificial hearts are unlikely to replace donor hears.“A donor heart in a good transplant can last 15 to 30 years,” he said. “Its going to be hard to replace that with a machine.”According to the report, patient who received the first self-contained heartAwas said to be in a good c

39、StoryNEW YORK,NY, January 5,2010. St.Martins Press has announced the release of the paperback edition of Picking Cotton, a remarkable true story of what novelist John Grisham calls an “account of violence, rage, redemption(救赎)，and, ultimately forgiveness.”The story began in 1987, in Burlington, Nort
40、h Carolina, with the rape of a young while college student named Jennifer Thompson. During her ordeal, Thompson swore to herself that she would never forget the face of her rapist, a man who climbed through the window of her apartment and assaulted her brutally._(46) When the police asked her if she
41、 could identify the assailant(袭击者)from a book of mug shots, she picked one that she was sure was correct, and later she identified the same man in a lineup.Based on her convincing eyewitness testimony, a 22-year-old black man named Ronald Cotton was sentenced to prison for two life terms. Cottons la
42、wyer appealed the decision, and by the time of the appeals hearing, evidence had come to light suggesting that the real rapist might have been a man who looked very like Cotton, an imprisoned criminal named Bobby Poole._ (47) Jennifer Thompson looked at both men face to face, and once again said tha
43、t Ronald Cotton was the one who raped her.Eleven years later, DNA evidence completely exonerated(证明清白)Cotton and just as unequivocally(明确地) convicted Poole, who confessed to the crime. _(48) “The man I was so sure I had never seen in my life was the man who was inches from my throat, who raped me, w
44、ho hurt me, who took my spirit away, who robbed me of my soul,” she wrote. “And the man I had identified so surely on so many occasions was absolutely innocent.”_ (49) Remarkably both were able to put this tragedy behind them, overcome the racial barrier that divided them, and write a book, which th
45、ey have subtitled “Our memoir of injustice and redemption.”Nevertheless, Thompson says, she still lives “with constant pain that my profound mistake cost him so dearly_ (50)”A. Another trial was held.B. I cannot begin to imagine what would have happened had my mistaken identification occurred in a c
46、apital caseC. Thompson was shocked and devastated.D. Jennifer Thompson decided to meet Cotton and apologize to him personally.E. During the attack, she made an effort to memorize every detail of his face , looking for scars , tattoos (纹身) or other identifying marks.F. Many criminals are sent to pris
