2020年全国英语等级三级试题及答案(卷三)
2020年全国英语等级三级试题及答案（卷三）I heard many parents complaining that their teenage children are rebelling. I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own two feet. But take a good look at the present rebellion. It seems that teenagers are taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own, most of them are clutching (紧握) at one another's hands for reassurance.They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up huddled (聚在一起) round listening to the same record. Their reason for thinking or acting in thusandsuch a way is that the crowd is doing it. They have come out of their cocoon (蚕茧) into a larger_cocoon.It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Industry has firmly carved out a teenage market. These days every teenager can learn from the advertisements what a teenager should have and be. And many of today's parents have come to award high marks for the popularity of their children. All this adds up to a great barrier for the teenager who wants to find his or her own path.But the barrier is worth climbing over. The path is worth following.You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records. You may have some thoughts that you don't care to share at once with your classmates. Well, go to it. Find yourself. Be yourself. Popularity will come —with the people who respect you for who you are. That is the only kind of popularity that really counts.1.In this passage, the author wants to tell ________.A.teenagers to try to pursue their real selvesB.readers to try to be popular with people aroundC.parents to try to control and guide their childrenD.people to try to understand and respect each other2.The author disapproves of rebelling teenagers ________.A.growing away from their parentsB.following the popularity trendC.walking a new way on their ownD.turning to their friends for help3.The phrase “larger cocoon”at the end of the second paragraph refers to ________.A.the distractive and variable societyB.the dazzling music worldC.the parental care and loveD.the popularity wave in the society4.What does the author think of advertisements?A.Convincing.B.Instructive.C.Influential.D.Authoritative.5.According to the author, what might happen when a teenager stands up against the popularity wave and follows his/her own path?A.He/She falls behind the time.B.He/She loses good friends.C.He/She faces all kinds of criticism.D.He/She gains valuable popularity.答案及解析1.A主旨大意题。

This process started at least 50 million years ago, creating the mountain range and the Qingzang Gaoyuan.以新视野大学英语3为教材的英语测试In some areas, where earthquakes have not relaxed the stressed crust for much longer, a slip of as much as 10 meters could be waiting to happen, which would cause an earthquake larger than any seen in the twentieth century.26.

It found that human-influenced climate change was raising the global death rates from illnesses including malnutrition (营养不良)and heat-related health problems.But even before its release, the report drew criticism from some experts on climate and risk, who questioned its methods and conclusions.Along with the deaths, the report said that the lives of 325 million people, primarily in poor countries, were being seriously affected by climate change. It projected that the number would double by 2030.Roger Pielke Jr., a political scientist at the University of Colorado, Boulder, who studies以新视野大学英语3为教材的英语测试disaster trends, said the Forum's report was "a methodological embarrassment" because there was no way to distinguish deaths or economic losses related to human-driven global warming amid the much larger losses resulting from thegrowth in populations and economic development in vulnerable (易受伤害的) regions. Dr. Pielke said tha t “climate change is an important problem requiring our utmost attention.” But the report, he said, "will harm the cause for action on both climate change and disasters because it is so deeply flawed (有瑕疵的)."However, Soren Andreasen, a social scientist at Dalberg Global Development Partners who supervised the writing of the report, defended it, saying that it was clear that the numbers were rough estimates. He said the report was aimed at world leaders, who will meet in Copenhagen in December to negotiate a new international climate treaty.In a press release describing the report, Mr. Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability to climate hazards while still curbing the emissions of the heat-trapping gases. More than 90% of the human and economic losses from climate change are occurring in poor countries, according to the report.31. What is the finding of the Global Humanitarian Forum?A Global temperatures affect the rate of economic development.B Rates of death from illnesses have risen due to global warming.C Malnutrition has caused serious health problems in poor countries.D Economic trends have to do with population and natural disasters.32. What do we learn about the Forum's report from the passage?A It was challenged by some climate and risk experts.B It aroused a lot of interest in the scientific circles.C It was warmly received by environmentalists.D It caused a big stir in developing countries.33. What does Dr. Pielke say about the Forum's report?A Its statistics look embarrassing.B It is invalid in terms of methodology.C It deserves our closest attention.D Its conclusion is purposely exaggerated.34. What is Soren Andreasen's view of the report?A Its conclusions are based on carefully collected data.B It is vulnerable to criticism if the statistics are closely examined.C It will give rise to heated discussions at the Copenhagen conference.D Its rough estimates are meant to draw the attention of world leaders.35.
