Laws are designed to make certain that people's rights are protected and that people respect each other's rights. Sometimes, however, laws are passed which are specific to a time or situation. For example, a town in Indiana once passed a law making it illegal to shoot open a can of food. Apparently, some gun-carrying citizens forgot their can openers and naturally enough, used their guns to do the job. This disturbed other citizens, and endangered their lives, so a law was passed to prevent it. Specific lawssometimes remain in existence long after the problem has disappeared. The laws then seem strange. For example, the Indiana law was no longer necessary when citizens stopped carrying guns and using them as can openers. Since the law was no longer needed, what once made sense now seems like nonsense.Sometimes laws designed to serve a good purpose were passed but somehow these became mixed up in their wording. As a result, the laws don't make sense. In one state there is a law which says that it is "illegal to move or to attempt to move a motor vehicle." Obviously, a massive traffic jam would occur if everyone suddenly obeyed that law. But no one does, of course, because the intention of the law was not to prevent owners from moving their own cars. It was to prevent people from moving (stealing) other people's cars.It is often harder to repeal a law than to pass one, so many of these old laws remain in existence. Because they no longer fit the way people live or because the problem no longer exists, these laws are ignored. Everyone understands that and life goes on. Thus, laws that once made very good sense, now seem like nonsense.1. According to the passage, laws are designed for the purpose of __A__.A. protecting people's rightsB. making people respect each otherC. preventing gun-carryingD. punishing criminals2. The word "job" in paragraph 1 refers to ___C____.A. workingB. shootingC. opening a canD. disturbing others3. The author used the Indiana law as an example to explain ___C___.A. how some laws are passed and changedB. how people in Indiana open cansC. why some laws may seem strangeD why people in Indiana no longer use their guns4. What's the problem with the law concerning motor vehicles? B .A. It leads to traffic jams.B. It is not clearly written.C. It is not designed to serve a good purpose.D. It has been out of date.5. We can conclude from the passage that ____D_____.A. a law system is necessary for every societyB. some laws that don't make sense may also get passedC. it is more difficult to change the old law than pass a new oneD. some laws may seem strange as time passesPassage2It is over 40 years since first atomic bomb was dropped on a major city in Japan. Yet even now its effect are showing themselves and may continue to do so for years to come. Much effort and human energy have been used to try to prevent such terrifying thing from happening again. So far there is no guarantee that it will not. Countries which already possess nuclear knowledge and resources have bombs stored away which are powerful enough to wipe out all life on earth.But this is not all. Other countries, which previously were not so advanced in technology, are gradually buying materials that can be used for making atomic devices. This nuclear energy will naturally be of great value in helping the economy of poor nations, but it also means that there are far more opportunities for the manufacture of bombs.The generation of electricity through nuclear power came directly from the original work on the atom bomb. Because of the increase in demand for energy and the possibility of decreasing supplies of oil and natural gas, the interest in electiricity has increased, One of the by-products of nuclear power stations is plutonium produced from nuclear fuel:plutonium is ingredient in bomb-making.This brings the problem to a full circle again. How can something so valuable and useful be controlled so that it works for the benefit and not the destruction of man?6. In the writer’s view, effects of dropping the first atomic bomb D .A are not overB may gone on foreverC could last much longerD will not be over in the near future7. The writer says that enough atomic bombs have already been manufactured toD .A wipe out JapanB last foreverC act as a peacr-keeping deviceD destroy all living things8. The writer believes that the advantage of less developed countries being able to make atomic devices is that it B .A gives them more opportunities for workB will help poor countries to become richerC will enable them to make better explosivesD will be of great value to them9. The writer implies that most people today do not reject nuclear weapons becauseC .A they are unimportantB they think that their existence will prevent countries from going to warC they are stored out of the wayD they have become accutomed to them10. The second paragraph tells us that the increased demand for electricity todayD .A has led to the decrease in supplies of oilB means that more countries are interested in nuclear powerC has increased the risk of accidental explosionsD has increased the very means of producing more atomic bombs1.Catalyst is the chemical which can be used repeatedly in a reaction withoutbeing consumed.催化剂是在反应过程中可重复使用且不会消失的化学物质。

)四、阅读理解:(本题共20分,每小题2分)Passage1A growing number of these attractions now allow customers to print e-tickets at home with large discounts off the gate price, in part to spur attendance that has declined in recent years.After boom times in the late 1990s, theme park attendance began to decrease, with an overall decline of about 4% over the past few y ears at North America’s 50 most- visited establishments, says James Zola, editor of Amusement Business. “The bloom was off the rose as we turned the corner into 2000, so there’s more discounting now,” he says.Discounting isn’t new to an industry tha t has long partnered with other commercial enterprises, such as soft drink companies, to offer deals. Print e-ticketing adds a new opportunity that not only brings savings but convenience as well, since it allows visitors to avoid the line at the gate.“If you can get in early before the lines fill up, you're getting more for your money,” says Robert Niles of the website Theme Park Insider.1. The word “attractions” (line 1, Para. 1) refers to A .A. theme parksB. bargainsC. e-ticketsD. discounts2. Why do more and more theme parks offer large discounts off gate price?B .A. To get in line at the parks this summer.B. To encourage more people to come to the parks.C. To enable people to get e-tickets at home.D. To reduce the attendance figure.3. What does the sentence “The bloom was off the rose” mean?D .A. the rose in the theme park was out of bloom.B. the year 2000 was lucky for the 50 establishments.C. the theme park attendance was like the rose.D. the best time for the theme parks was gone.4. What is the new opportunity e-ticketing brings to the theme parks?C .A. The theme park industry will be more profitable.B. Soft drink companies will be better partners of the parks.C. The tour to the parks will be more convenient.D. Visitors to the parks will have more discounts.5. The last sentence of this passage is based on the idea that D .A. it is wise to surf online.B. discounting isn’t everything.C. e-ticketing attracts more partners.D. time is money.Passage2A mysterious “black cloud” approaches the earth –our planet’s weather is severely affected.Throughout the rest of June and July temperatures rose steadily all over the Earth. In the British isles the temperature climbed through the eighties, into the nineties, andmoved towards the hundred mark. People complained, but there was no serious disaster.The death number in the U. S. remained quite small, thanks largely to the air-conditioning units that had been fitted during previous years and months. Temperatures rose to the limit of human endurance throughout the whole country and people were obliged to remain indoors for weeks onend.Occasionally air-conditioning units failed and it was then that fatalities occurred.Conditions were utterly desperate throughout the tropics as may be judged from the fact that 7943 species of plants and animals became totally extinct. The survival of Man himself was only possible because of the caves and cellars he was able to dig. Nothing could be done to reduce the hot air temperature. More than seven hundred million persons are known to have lost their lives.Eventually the temperature of the surface waters of the sea rose, not so fast as the air temperature it is true, but fast enough to produce a dangerous increase of humidity. It was indeed this increase that produced the disastrous conditions just remarked. Millions of people between the latitudes of Cairo and the Cape of Good Hope were subjected to a choking atmosphere that grew damper and hotter from day to day. All human movement ceased. There was nothing to be done but to lie breathing quickly as a dog does in hot weather.By the fourth week of July conditions in the tropics lay balanced between life and total death. Then quite suddenly rain clouds appeared over the whole globe. The temperature declined a little, due no doubt to the clouds reflecting more of the Sun’s radiation back into space, But conditions could not be said to have improved. Warm rain fell everywhere, even as far north as Iceland. The insect population increased enormously, since the burning hot atmosphere was as favorable to them as it was unfavorable to Man many other animals.6. In the British Isles the temperature C.A stayed at eightyB ranged from eighty to ninetyC approached one hundredD exceeded the hundred mark7. Few people in the United States lost their lives because D.A the temperature was tolerableB people remained indoors for weeksC the government had taken effective measures to reduce the hot temperatureD people were provided with the most comfortable air-conditioners8. Millions of people in Cairo and the Cape of Good Hope were subjected to a choking atmosphere because B.A the temperature grew extremely hotB the temperature became damper and hotter as the humidity of the surface waters of the sea increasedC their conditions were too dangerousD nothing could be done with the hot temperature9. By the fourth week of July conditions in the tropics were such that D.A human survival would be impossibleB more and more people would lose their livesC fewer people could be savedD survival or death was still undecided10. The insect population increased due to A.A the hot airB the tropical climateC the rain cloudsD the damp atmosphere(评分标准:每小题中与答案一致得2分;否则得0分。
