Text 2 In Denver, five were pummeled to death and two more beheaded. In Richmond, Virginia, one was beaten, stabbed and beheaded, his head then carried nearly a mile and placed for display on a footbridge. In Seattle, one was stabbed 18 times, another beaten bloody, then stabbed. They were all homeless people killed over the last year. And these were just the killings that make the news. Exactly how many homeless people have been victims of savage attacks is unknown. Police departments do not tabulate crimes against homeless people, and in many cases, such as several beatings that have frightened the large homeless population in San Francisco, those who survive attacks often do not report them. In many cases, because many people on the streets are mentally ill or drug addicted or both, they are easier to victimize and harder to help, the police say, since they are often unable to describe the time and place of their attacks or their attackers. Surveys show that high school students often call the homeless bums and drunks who are too lazy to work. Even some officials would say these people don’t count. What appears certain is that living on the streets is becoming more dangerous. In the last few years, police departments across the country have reported more frequent, more vicious attacks on those who are homeless. Nearly always, the victims are ambushed as they sleep. Nearly as often, the suspects, who are not always caught, are described as young men who appear to attack for no reason. In some cases, suspects call it "bumbashing"or "troll-busting," police say. Attacks against homeless people rarely get attention. But nationally, violence against people who are unsheltered is becoming so common that the Congress is asked to consider "homeless people" as a maligned minority, or protected class, in drafting any new legislation against hate crimes. No one can say for sure why young people in particular seem to be attacking homeless people in increasing numbers. But looking at arrests in cases of violence against homeless people over several years, by far the majority of the suspects were young teenagers, or even pre-teenage boys, who bragged about the attacks afterward. Officials believed that the homeless were singled out probably because they are accessible, anonymous and stigmatized as "throwaways of society." Many say crackdowns on homeless people for sitting, sleeping or lying in public spaces are a significant factor in the increased attacks. In Chicago, more of these kinds of attacks happened with increased "gentrification’ of the city. The police often keep people off the streets where homeless people live. In doing so, we were obviously sending a message to our young people that homeless people are not worthy of their respect. In the last paragraph, the phrase "single out" means

Directions:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2.All U. S. nuclear weapons production facilities are presently closed down, and if the various agreements are adhered to, those facilities will never be required except for one critical capability. All modern nuclear weapons use uranium (铀), plutonium (钚), and tritium (氚). Uranium and plutonium have very long half-lives, and there is large surplus of these materials.Tritium, however, has a relatively short half life of about 12.6 years, so about 5 percent of the amount on hand must be replaced each year to maintain the current inventory. (46) Because of the large retirement of nuclear weapons by the United States in compliance with early agreements and national policy, tritium from retired weapons has been used to make up that lost through natural decay. (47) However, in about 10 to 15 years, depending on future negotiations, the United States will need a guaranteed supply of tritium to maintain its stockpile at whatever level is agreed on.In anticipation of this future need to produce tritium, Defense Office Executive is pursuing two technologies. One uses a nuclear reactor that could also produce electricity whose sale would recover not only the capital cost of the reactor but also its annual operational cost. (48) Unfortunately, the present Administration has a definite bias against nuclear power, so an alternative method is also being pursued even though it is agreed that it will cost twice as much as a reactor and use as much electricity as a reactor would produce. This technology uses an accelerator to produce high-energy protons that in turn produce neutrons.The main argument for the accelerator is that it produces no conventional nuclear wastes. (49) Proponents readily admit that it will produce radioactive materials, but with a relatively short half-life compared with that of wastes from spent nuclear fuel. The fact that the accelerator will require the equivalent of a nuclear power plant to supply its electricity is ignored.(50) Proponents also neglect to mention that about 22 percent of all electrical energy generated in the United States comes from nuclear power plants, so that 22 percent of the power used by the accelerator will generate conventional nuclear wastes, in addition to those the accelerator produces. There is an alternative to either the reactor or the accelerator, which is simply to buy the required tritium from Canada or Russia. Proponents also neglect to mention that about 22 percent of all electrical energy generated in the United States comes from nuclear power plants, so that 22 percent of the power used by the accelerator will generate conventional nuclear wastes, in addition to those the accelerator produces.
