1、Gun Rights in the US Immediately after the shooting at Virginia Tech University, Americans gathered to mourn the dead. The president and the state governor both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons. Strictly speaking, the US is not the only country where gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the few countries that seems unwilling and politically incapable of doing anything serious to stop it. In countries like Britain and Canada. The government adopted stricter gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby and the electoral system. The powerful National Rifle Association, the major supporter of gun rights in the US, is too strong for any party to take on. Most Republicans oppose gun controls anyway. Over the years, the Democrats have found that they can either campaign for gun control or win power, not both; they prefer power. According to the US Bureau of Justice Statistics, firearm incidents accounted for nine percent of the 4.7 million violent crimes in 2005. So, although opinion polls show most Americans want stricter gun laws, many don\'t want to give up their arms they ____ to protect themselves. Dave Hancock, a Virginia gun lover, is one example. In an interview he said. "If one professor in Virginia incident had been carrying a legal weapon they might have been able to stop all this. " In his opinion, the massacre is an argument for more people to carry, weapons, not fewer. But at the root of Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government , commented UK\'s Guardian newspaper. One Virginia resident, who had a permit to carry; a concealed firearm, told the Guardian thin itwas every American\'s responsibility to have a gun. "Each person," he said, "should not rely solely on the government for protection. " 【单选题】

2、PopulationThe advantages and disadvantages of large population have long been a subject of discussion among economists. ____. To feed a large population, inferior land must be cultivated and the good land worked intensively. produces less and this means a lower average income than could be obtained with a smaller population . Other economists have argued that a large population gives more scope for specialization and the development of facilities such as ports, roads and railways, which are not likely to be built unless there is a big demand to justify themOne of the difficulties in carrying out a worldwide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In the developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, concern of government to plane a limit on the birth rate, whatever the consequences may be. In a highly industrialized society the problem may be more complex. A decreasing birth rate may lead to unemployment it results in a declining market for manufactured goods. When the pressure of population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.【单选题】

3、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people or singles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily married people, according to the study."There seems to be some unique health benefits from marriage. It\'s not just being named that benefits health-what\'s really the most protective of health is having a happy marriage," study author Julianne Holt Lunstad, a psychologist who specializes in relationships and health, said in a prepared statement.The study included 204 married and 99 single adults who wore portable blood - pressure monitors for 24 hours. The monitors recorded blood pressure at random intervals and provided a total of about 72 readings."We wanted to capture participants\' blood pressure doing whatever they normally do in everyday life. Getting one or two readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood ____ among married people, especially those in happy marriages dropped more during sleep than in single people."Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.The study was published in the March 20 issue of the journal Annals (年刊) of Behavioral Medicine.The study also found that unhappily married adults have higher blood pressure than both happily married and single adults.Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet and having regular doctor visits.

5、Life Expectancy in the Last Hundred YearsA hundred years ago, life expectancy in developed countries was about 47 in the early 21st century, men in the United States and the United Kingdom can expect to live to about 74. Women to about 80, and these ages are rising all the time. What has brought about these changes? When we look at the life span of people 100 years ago, we need to look at the greatest killers of the time. In the early 20th century, these were the acute and oftenhighly infectious diseases such as smallpox. Many children died very young from these diseases and others, and the weak and elderly were always at risk.In the developed world these diseases are far less deadly today, and in some cases have almost disappeared. A number of factors have led to this: improvements in sanitation and hygiene, the discovery and use of antibiotics, which make bacterial diseases much less dangerous, and vaccinations against common diseases. ____, people\'s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better and warmer housing, and better understanding of nutrition.Genetically, we should all be able to live to about 85 but while people do live longer today, there are still some big killers around that are preventing US from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those spread by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect older people, but there are worrying trends in the developed world with problems such as obesity leading to more heart disease and illnesses such as diabetes at younger ages.The killers today can be classed as "lifestyle diseases", which means that it may be possible to halt their progress.【单选题】
