2019高考英語考前50天（閱讀理解）訓(xùn)練秘笈（1）及解析ACellphones: is there a cancer link?Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors. Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks theres a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also theres a greater than 90 percent chance that cellphones can cause brain tumors. “Its apparent now that theres a real risk, ” said Carpenter. But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病學(xué)) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I dont support warning labels for cellphones, ” said Linet. “We dont have the evidence that theres much danger. ”Studies so far suggest a weak connection between EMFs(電磁場) and illness so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. Its funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far dont suggest a strong link between cellphone use and cancer risk. 44. From the passage we can learn that some people are worried because _. A. they have evidence that the use of cellphones can lead to cancerB. they make a fuss over cellphone useC. some experts have given a warningD. cellphones are responsible for brain tumors45. By saying “I dont support warning labels for cellphones, ” Dr Martha Linet has the idea that _. A. the worrying is unnecessaryB. cancer-warning labels should be on cellphonesC. there is a link between cellphones and cancerD. cellphones have nothing to do with cancer46. Which of the following best describes the attitude of the author towards the debate? A. Optimistic. B. Objective. C. Opposite. D.

In one experiment, some of the participants were first stressed by having to give a speech and do difficult math problems in front of an audience; in the other, some were stressed by having to keep their hands in ice water. In both cases, the stressed participants remembered the rewarded material more accurately and the punished material less accurately than those who hadnt gone through the stress.This phenomenon is likely not surprising to anyone who has tried to resist eating cookies or smoking a cigarette while under stress at those moments, only the pleasure associated with such activities comes to mind. But the findings further suggest that stress may bring about a double effect. Not only are rewarding experiences remembered better, but negative consequences are also easily recalled.The research also found that stress appears to affect decision-making differently in men and women. While both men and women tend to focus on rewards and less on consequences under stress, their responses to risk turn out to be different.Men who had been stressed by the cold-water task tended to take more risks in the experiment while women responded in the opposite way. In stressful situations in which risk-taking can pay off big, men may tend to do better, when caution weighs more, however, women will win.This tendency to slow down and become more cautious when decisions are risky might also help explain why women are less likely to become addicted than men: they may more often avoid making the risky choices that eventually harden into addiction.64.We can learn from the passage that people under pressure tend to _.A. keep rewards better in their memoryB. recall consequences more effortlesslyC. make risky decisions more frequentlyD. learn a subject more effectively65.According to the research, stress affects people most probably in their _.A. ways of making choicesB. preference for pleasureC. tolerance of punishmentsD. responses to suggestions66.The research has proved that in a stressful situation, _.A. women find it easier to fall into certain habitsB. men have a greater tendency to slow downC. women focus more on outcomesD. men are more likely to take risks【答案及解析】64.A 第一段中，acute stress affects the way the brain considers the advantages and disadvantages, causing it to focus on pleasure and ignore the possible negative consequences of a decision,可知壓力下旳人們經(jīng)常會keep rewards better in their memory.65.A 第二段中，The research suggests that stress may change the way people make choices in predictable ways.66.D 第七段中，Men who had been stressed by the cold-water task tended to take more risks in the experiment while women responded in the opposite way.可以看出是男性在壓力下更容易冒險*結(jié)束BWho is your role model? Normally the answer to this question would be anyone around you who you find truly inspiring. It could also be someone like J. K. Rowling or Martin Luther King. Jr. , who have proven to be strong and intelligent people. However, in todays world, stars are regarded as role models along with the heroes listed above, despite their intentions or actions. Teens attempt to imitate their actions for two major reasons. Firstly, to be fashionable and accepted by popular culture, and secondly because stars actions are so well documented by the media that it seems to grab our attention and turns it to following stars lives. Much of the reports about stars is shocking and exhibits bad morals or lifestyles that arent right for teenagers. In addition, almost everything stars do is described beyond truth to make a shocking story by taking it to the next level. However, teens must take responsibility for their actions. We cant always blame stars for influencing us. Only you have control over yourself and only you choose to do something. Our bodies and actions are in the hands of no one else. Now, who ever said stars are role models? Whether they choose to be or not, stars set examples as soon as they step into the spotlight. With reporters following and recording every move they make, it is impossible not to be watched and then be imitated. These people influence teens whether or not they want to. Why should someone who doesnt want to be setting an example set one? So，should we look up to them or to people who are true and good role models? Its our responsibility as teens to know right from wrong, and its time for us to take responsibility for our actions. In doing so，we will lean toward those inspiring people that want to be setting an example, and follow in their steps to be like them. 47.
