阅读材料,回答下面的题目。Deport them or notIn a country that defines itself by ideals,not by shared blood,who should be allowed to come,work and live here?In the wake of the Sept.1 1 attacks these questions have never seemed more pressing.On Dec.11,2001,as part of the effort to increase homeland security,federal and local authorities in 14 states staged“Operation Safe Travel”-raids on airports to arrest employees with false identification(身份证明).In Salt Lake City there were 69 arrests.But those captured were anything but terrorists,most of themillegal immigrants from Central or South America.Authorities said the undocumented workers’illegal status made them open to blackmail(讹诈)by terrorists.Many immigrants in Salt Lake City were angered by the arrests and said they felt as if they were being treated like disposable goods.Mayor Anderson said those feelings were justified to a certain extent,“We’re saying we want you to work in these places,we’re going to look the other way in terms of what our laws are,and then when it’s convenient for us,or when we can try to make a point in terms of national security,especially after Sept.1 1,then you’re disposable.There are whole families being uprooted for all of the wrong reasons,”Anderson said.If Sept.1 1 had never happened.the airport workers would not have been arrested and could have gone oil quietly living in America.probably indefinitely.Ana Castr0,a manager at a Ben&Jerry’s ice cream shop at the airport,had been workin9 10 years with the same false Social Security card when she was arrested in the December airport raid.Now she and her family are living under the threat of deportation(驱逐出境).Castro’s case is currently waiting to be settled.While she awaits the outcome,the government has granted her permission to work here and she has returned to her job at Ben&Jerry’s.According to the author,the United States claims to be a nation__________.
阅读材料,回答下面的题目: What We Take from and Give to the Sea As long as we have been on earth, we have used the sea around us. We take from the ocean, and we give to it. We take fishes from the ocean-millions of kilograms of fish, every year, to51millions of people. We even52their bones for fertilizer. We take minerals from the ocean. One way to get salt is to53seawater in shallow basin and leave until it evaporates( 蒸发 ). Along with salt, other minerals are left 54 evaporation.Much gold and silver drift dissolved in the waters of the sea, too. But the sea does not give them 55 by simpleevaporation.56gifts from the sea are pearls, sponges( 海绵) and seaweed. Pearls57jewelry. Natural sponges become cleaning aids. Seaweed becomes 58 of many kinds-even candy, and ice cream - as well as medicine. Believe it or not, fresh water is another 59 from the sea. We cannot drink ocean water. Some of its contents may. 60 illness. But ocean water becomes fresh water when the salts are 61 . In the future, we will find ourselves 62 more and more on fresh water from the sea. The sea63us food, fertilizer, minerals, water, and other gifts. What do we give the sea? Garbage. We pollute the ocean 64 we use it as a garbage dump. Huge as it is, the ocean cannot hold all the water that we pour into it. 65 garbage into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts ,more than ever.请在第___________处填上正确答案.

回答下面的题目:Exercise Being Good or BadCan exercise be a bad thing? Sudden death during or soon after strenuous exertion on the squash court or on the army training grounds, is not unheard of. 51 trained marathon runners are not immune to fatal heart attacks. But no one knows just 52 common these sudden deaths linked to exercise are. The registration andinvestigation of such 53 is very patchy; only a national survey could determine the true 54 of sudden deaths in sports. But the climate of medical opinion is shifting in 55 of exercise, for the person recovering from a heart attack as 56 as the average lazy individual. Training can help the victim of a heart attack bylowering the 57 of oxygen the heart needs at any given level of work 58 the patient can do more before reaching the point where chest pains indicate a heart starved of oxygen. The question is, should middle-aged people, 59 .particular, be screened for signs of heart disease before 60 vigorous exercise?Most cases of sudden death in sport are caused by lethal arrhythmias in the beating of the heart, often in people 61 undiagnosed coronary heart disease. In North America 62 over 35 is advised to have a physical check-up and even an exercise electrocardiogram. The British, on the whole, think all this testing isunnecessary. Not many people die from exercise, 63 , and ECGs ( 心电图 ) are notoriously inaccurate. However, two medical cardiologists at the Victoria Infirmary in Glasgow, advocate screening by exercise ECG for people over 40, or younger people 64 at risk of developing coronary heart disease. Individuals showing a particular abnormality in their ECGs 65 , they say, a 10 to 20 times greater risk of subsequently developing signs of coronary heart disease, or of sudden death.第51题应选:
回答下面的题目: The Supercomputer Network1. Recently ten laboratories run by governments in different parts of the world have become linked. Their computers have been connected so they can "talk" to each other. This may not seem very dramatic news, but it is the beginning of a development that will increase the power of the Internet tremendously.2. The Internet is an interconnected ( 互联 ) system of networks that connects computers round the world and facilitates the transmission and exchange of information. The way that you use the lnternet is by accessing this network. This depends on the power that your system allows you to use. The power of your computer is responsible for how fast you can download ( 下载 ) files, how much data you can store, etc. If your computer is old and slow, accessing the information can be very difficult.3. The new development in information technology has been called "the grid" (网络技术), and it will be a network of computers that are linked together. The "grid" will work in a different way from the Internet, enabling you to get the power of the biggest computers in the world on your computer. Accessing the information will no longer depend on the power of your computer. The idea is that while you accessinformation, you will also have access to the power of the bigger computer stations.4. One advantage of this revolutionary idea is that geographical location will become irrelevant. The "grid" will decide which are the best parts of a worldwide network to do the job you want. This means that you may be accessing a computer in Japan to solve a problem in Alaska.5. The "grid" can be compared to having an efficient personal assistant. You can give your assistant a task and "he" will do it for you. The assistant will do the preliminary research, collect the data, compare them and decide on the best course of action by accessing any of the computer centres in the "grid" that happen to have the relevant information. All you have to do is assign the task, sit back and wait.6. At present, possible applications of the "grid" in scientific research are being explored. While it has taken about fifteen years for Internet use to become widespread, experts believe that the "grid" could be up and running for private individuals far more quickly. Scientists working on "grid" projects are convinced that it will be as widely used as the web in the next ten years.Paragraph 2__________
