单选题_____A conductingB encounteringC wagingD combating

考题 Of the many problems in the world today, none is as widespread, or as old, as crime. Crime has many forms, including crimes against property, person, and government. Crime, in all its forms, penetrates every layer of society and touches every human being. You may never have been robbed, but you suffer the increased cost of store- bought items because of others’shoplifting.Your house is not worth as much today as it was a few years ago because of the increased crime rate in your neighborhood. Perhaps your business is not doing as well as it used to because tourism is down due to increased terrorism in your part of the world.Crime, especially violent crime, has risen to a point where many people are afraid to walk al one in their own neighborhoods, afraid to open their door after dark, afraid to speak out and voice their own opinions. Some citizens have reacted by arming themselves with various weapons, legal and illegal, to defend themselves. Citizen groups have taken the law into their own hands by forming their own vigilante groups to administer judgment when they feel that their criminal justice system has not performed its duty.Experts argue whether the number of crimes committed is actually on the rise or whether there is simply a rise in the number of crimes reported. This issue is particularly true in cases of marriage violence, the abuse of spouse or children. Throughout much of history, cases of family violence and neglect often went unreported because of the attitude of society, which considered family matters to be private.Other experts argue about who is really to blame for criminal behavior. the individual or society. Researchers in the United States and Canada have identified several factors in society that contribute to the crime rate: massive urbanization, unemployment and poverty, and a large immigrant population. Other countries are more affected by factors such as politics, government corruption, and religion.(1)What does the passage mainly discuss?A、Crime the widespread problem.B、The results caused by increasing violent crime.C、Factors contributing to the crime rate.D、Citizen groups combating crimes.(2)The word shoplifting in line 4 is closest in meaning to _____________.A、the crime of lifting the banB、the crime of moving the shops awayC、the crime of robbing things from shopsD、the crime of stealing things from shops(3)Why does the author in Paragraph 2 mention citizen groups forming their own vigilante groups?A、To show the criminal justice system is not justB、To show citizens are powerful in combating crimesC、To show crime is a serious social problemD、To show citizens have rights in combating crimes(4)According to the passage, which of the following are the factors contributing to United States’criminal behavior?A、Politics, unemployment, poverty and a large immigrant population.B、Massive urbanization, unemployment and poverty, and a large immigrant population.C、Politics, government corruption, poverty and religion.D、Massive urbanization, unemployment and poverty, and government corruption.(5)Which of the following statements is TRUE according to the passage?A、Since you have never been robbed, you are not a victim of crime.B、Some people use illegal weapons to defend themselves.C、Only the individual should be responsible for the criminal behavior.D、Family violence and neglect are considered family matters, and therefore private, so they are not crimes.

考题 Text 4There have been rumors. There’s been gossip. All Hollywood is shocked to learn that Calista Flockhart, star of Fox’s hit TV show Ally McBeal, is so thin. And we in the media are falling all over ourselves trying to figure out whether Flockhart has an eating disorder, especially now that she has denied it. Well, I’m not playing the game. If the entertainment industry really cared about sending the wrong message on body image, it wouldn’t need so many slender celebrities in the first place.But the fact remains that 2 million Americans—most of them women and girls—do suffer from eating disorders. In the most extreme cases they literally starve themselves to death. And those who survive are at greater risk of developing brittle bones, life-threatening infections, kidney damage and heart problems. Fortunately, doctors have learned a lot over the past decade about what causes eating disorders and how to treat them.The numbers are shocking. Approximately 1 in 150 teenage girls in the U. S. falls victim to anorexia nervosa, broadly defined as the refusal to eat enough to maintain even a minimal body weight. Not so clear is how many more suffer from bulimia, in which they binge on food, eating perhaps two or three days’ worth of meals in 30 minutes, then remove the excess by taking medicine to move the bowels or inducing vomiting. Nor does age necessarily protect you. Anorexia has been diagnosed in girls as young as eight. Most deaths from the condition occur in women over 45.Doctors used to think eating disorders were purely psychological. Now they realize there’s some problematic biology as well. In a study published in the Archives of General Psychiatry recently, researchers found abnormal levels of serotonin, a neurotransmitter in the brain, in women who had been free of bulimia for at least a year. That may help explain why drugs have allowed a lot of people to stop swallowing in large doses of food. Unfortunately, the pills don’t work as well for denial of food. Nor do they offer a simple one-stop cure. Health-care workers must re-educate their patients in how to eat and think about food.How can you tell if someone you love has an eating disorder? “Bulimics will often leave evidence around as if they want to get caught.” Says Tamara Pryor, director of an eating-disorders clinic at the University of Kansas in Wichita. Anorexics, by contrast, are more likely to go through long periods of denial.第36题：We can infer from the first paragraph that _____.［A］ the media has mislead the public’s view of celebrities［B］ there is much misunderstanding about eating disorders［C］ body image concerns are an indication of eating disorders［D］ the entertainment industry is combating eating disorders

考题 Passage 2 A great deal of attention is being paid today to the socalled digital divide — the division of the world into the info(information) rich and the info poor. And that divide does exist today. My wife and I lectured about this looming danger twenty years ago. What was less visible then, however, were the new, positive forces that work against the digital divide. There are reasons to be optimistic.There are technological reasons to hope the digital divide will narrow. As the Internet becomes more and more commercialized, it is in the interest of business to universalize access — after all, the more people online, the more potential customers there are. More and more governments, afraid their countries will be left behind, want to spread Internet access. Within the next decade or two, one to two billion people on the planet will be netted together. As a result, I now believe the digital divide will narrow rather than widen in the years ahead. And that is very good news because the Internet may well be the most powerful tool for combating world poverty that we've ever had.Of course, the ue of the Internet isn't the only way to defeat poverty. And the Internet is not the only tool we have. But it has enormous potential.To take advantage of this tool, some impoverished countries will have to getover their outdated anticolonial prejudices with respect to foreign investment. Countries that still think foreign investment is an invasion of their sovereignty might well study the history of infrastructure (the basic structural foundations of a society) in the United States. When the United States built its industrials infrastructure, it didn't have the capital to do so. And that is why America's Second Wave infrastructure — including roads, barbors, highways, prots and so on — were built with foreign investment. The English, the Germans, the Dutch and the French were investing in Britain's former colony. They financed them. Immigrant Americans built them. Guess who owns them now? The Americans. I believe the same thing would be true in places like Brazil or anywhere else for that matter. The more foreign capital you have helping you build your Third Wave infrastructure, which today is an electronic infrastructure, the better off you're going to be. That doesn't mean lying down and becoming fooled, or letting foreign corporations run uncontrolled. But it does means recognizing how important they can be in building the energy and telecom infrastructures needed to take full advantage of the Internet.第55题：Digital divide is something _______ .A getting worse because of the InternetB the rich countries are responsible forC the world must guard againstD considered positive today

考题 Questions 184-188 refer to the following article. President Barack Obama has issued his call to put global warming at the top of the international agenda, pledging to push for coordinated action by the world's biggest countries to tackle problem of climate change. In the speech, the US president on Tuesday laid out a three-pan plan to deal with climate change using the power of his office. He outlined a strategy to cut the US's carbon pollution by reducing emissions from coal-fired power plants; to prepare the US for the impact of climate change, such as the super storm that ravaged the New Jersey coastline last year, and to lead the world by example in combating changing climate. "While no single step can reverse the effects of climate change, the president believes we have a moral obligation to our kids to leave them a planet that's not polluted and White House official said. The coal industry said the proposals could prove devastating-----shares in US coal mining companies have been falling sharply-but Mr. Obama ' s speech was being watched closely around the world. In Europe, where the Eurozone crisis has pushed the climate change agenda firmly into the political background, environmental campaigners said they hoped Mr.Obama's speech would puncture arguments tackling global warming as bad for the economy.”If you have got the US and China moving, then the argument that the EU is going it alone clearly doesn't stand up to scrutiny anymore," said Tom Brookes of the European Climate Foundation. The president said he would seek to expand new and existing international initiatives,including bilateral initiatives with China, India and other big emissions countries. According to the passage, what was the possible solution for the problem? A. Seeking international coordination of big emission countries B. Making EU 's action ahead of environment campaigners C. Enhanced awareness of environmental campaigners D. Expanding the influence of some Asian countries

考题 Questions 11 to 15 are based on the following passage. Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu (流感) may make a difference in how long the misery lasts. The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come. The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for. Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms. The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症)，a rare but serious condition of the liver and central nervous system. There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one. If children have flu-like symptoms, their parents （）A、are advised not to give them aspirinB、should watch out for signs of Reye syndromeC、are encouraged to take them to hospital for vaccinationD、should prevent them from mixing with people running a fever
