In the past, man did not have to think about protection of the environment. There were very few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive. Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on land. Yet, we continue to use more powerful machines to cut down more and more trees. We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste is still put into rivers, but there are few laws to stop this. We also know that if the population of the countries in the world is to rise at the present rate in a few years, there will not be enough food. What can we do to solve these problems? If we eat more vegetables and less meat, there will be more food available for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept. Our natural resources will last longer if we learn to recycle them. The world population will not rise so quickly if people use modern methods of birth control. Finally, if all of us think about the problem, we will have a better and cleaner planet in the future. |

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration (集中)of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of coal and oil is creating a "greenhouse effect" - raising the world"s average temperature. If this view is correct and the world"s temperature is raised only a few degrees, much of the polar ice will melt and cities such as Newk York, Boston, Miami, and Newk^ Orleans will be in water. Another view, less widely held, is that increasing particular matter in the atmosphere is preventing sunlight and lowering the earth"s temperature - a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen though one recent government reports that the greenhouse effect is very possible. Perhaps, if we are lucky enough, the two tendencies will offset(抵消)each other and the world"s temperature will stay about the same as it is now. Driven by economic profits, people don"t think about the damage on our environment caused by the "advanced civilization". Maybe the air pollution is the price the human beings have to pay for their development. But is it really worth? |
2. As pointed out at the beginning of the passage, people used to think that air pollution ________. |
A. caused widespread damage in the countryside B. affected the entire eastern half of the United States C. had damaged effect on health D. existed only in urban and industrial areas |
3. As to the greenhouse effect, the author ________. |
A. shares the same view with the scientists B. is uncertain of its happening C. rejects it as being ungrounded D. thinks it will destroy the world soon |
4. It can be concluded from the last paragraph that ________. |
A. lowering the world"s temperature only a few degrees would lead major farming areas to disaster B. raising the world"s temperature only a few degrees would not do much harm to life on earth C. almost no temperature variations have occurred over the past decade D. the world"s temperature will remain constant in the years to come |
5. This passage is mainly about ________. |
A. the greenhouse effect B. the burning of coal and oil C. the potential effect of air pollution D. the likelihood of a newk ice age |
信息匹配。 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项。 Many solutions we seek with regard to achieving sustainability(可持续性) are within our reach. That"s the lesson our school"s Environment Club has learned over the past two years. We"ve reduced the amount of our waste at our school by 25 per cent. 1 We have the evidence we need to suggest we are making a difference. If you are interested in leading your school on a similar journey of change, here are some tips. 2 Examine the garbage can to find out how much of your school"s garbage could be picked out from the waste stream and be reused. We found that more than 80 percent of our waste could have been reused, recycled or composted(制成堆肥). Prepare dustbins there. 3 You will find you can cover the cost of the purchase of the dustbins within a few months simply by selling the bottles and other items you collect. Compost the waste. Start a composting system in your school. You may reduce your waste by as much as 50 percent. Be sure to talk with your teachers and your cafeteria staff to get them onside. Share your success. Let your community know what you"ve accomplished. 4 Ask your teachers if you can talk to their classes, let your parent group know what you"re doing, and present a report to the president of your school. 5 Whether you spend a few moments in a quiet place or the whole day walking along a beautiful beach, time outdoors will remind you why the work you do for the environment is so worthwhile. A. Dig in. B. Reward yourself. C. Do outdoor activities. D. They"ll feel proud of you. E. We need to go further, and we will. F. Invite your friends to join your cause. G. Make sure every classroom has dustbins for recycling. |

Wherever life takes you after A-level results day, it"s likely to bring increased independence. That means it"s time to take care of yourself. Students, take note. When you arrive at university, make sure you register with a doctor near your term-time address. If there is a university doctor at your institution, they will be your best choice. If not, ask student services for a recommendation. Once registered, do everything you can to make sure you never have to pay them a visit. Don"t take unnecessary health risks. Cook meat thoroughly. Throw food away if it"s out of date. Clean up after yourself. Food poisoning can be harmful, but it"s easy to avoid if you pay due care and attention. University often brings a certain lifestyle, and while that"s usually a whole lot of fun, it can quickly tip into a whole lot of sorrow. Know your limits when it comes to alcohol. Habitual drinking can be dangerous, and while every student will have nights of excess, these should be the exception, not the norm. Look out for your friends, too. If you"re worried about alcohol or substance abuse, visit alcoholics-anonymous.org.uk <http://alcoholics-anonymous.org.uk> or ukna.org http://ukna.org for free and confidential support. Anyone living with teenagers and young adults, especially in environments such as halls of residence, must accept that germs (细菌) will be shared. Bugs and colds will spread like wildfire. Living communally brings certain health risks, and meningitis is probably the most serious of these. Symptoms include a rash, stiff neck and an aversion to bright lights. It"s rare, but seek immediate medical attention if you"re concerned (meningitis.org <http://meningitis.org>). Gappers, meanwhile, may need to consider specific health risks. If you"re planning a trip abroad, especially in rural areas of poor countries, make sure you get the necessary vaccinations (预防注射) in good time before you leave. Research these at www.netdoctor.co.uk <http://www.netdoctor.co.uk>. You should be able to get everything you need from your doctor, although you may have to give them notice and you may have to pay, even on the NHS (英国国家医疗服务体系). If you also need to take medication while you"re away, such as anti-malarials, do it faithfully. On a general note, whoever you are, wherever you are and whatever you do with your time, never walk alone at night, especially in quiet and badly lit areas. Always carry your phone. Never get in an unlicensed cab. Be careful who you trust. Respect your new independence, and keep yourself safe. |

We produce 500 billion of plastic bags in a year world-wide and they are thrown away polluting oceans, killing wild-life and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution. The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has discovered a-way to make plastic bags degrade(降解)in as few as 3months, a finding that won him first prize at the Canada-Wide Science Fair, a $10,000 prize, a $20,000 scholarship, and a chance to revolutionize a major environmental issue. Burd"s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms(微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions. With this goal in mind, he ground plastic bags into a powder and concocted(调制)a solution of household chemicals, yeast(酵母)and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed(暴露)to the live bacteria was 17% lighter than the control after six weeks. The inputs are cheap: maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide. "Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself." said Daniel Burd. |

Secondhand smoke isn"t just a health threat to people. It can also hurt dogs and cats,veterinarians say. According to the Centers for Disease Control and Prevention,more than 126 million Americans who don"t smoke are exposed to secondhand smoke in their homes,vehicles,workplaces,and public places. This exposure causes thousands of lung cancer and heart disease deaths among nonsmokers every year,according to the California Environmental Protection Agency. "Making the leap from the effects of secondhand smoke on humans to their effects on pets isn"t a big one," says veterinarian (兽医专家) Carolynn MacAllister of Oklahoma State University. "There have been a number of scientific papers recently that have reported the significant health threat secondhand smoke poses to pets," MacAllister said. "Secondhand smoke has been associated with oral cancer and lymphoma in cats,lung and nasal cancer in dogs,as well as lung cancer in birds." Studies have also shown that dogs living in a smoking household are susceptible to cancers of the nose and sinus area,particularly if they are a long-nosed breed,because their noses have a greater surface area that is exposed to carcinogens and a greater area for them to accumulate. Dogs affected with nasal cancer normally don"t survive for more than one year. "Short and medium-nosed dogs are more susceptible to lung cancer,because their shorter nasal passage aren"t as effective at accumulating the inhaled secondhand smoke carcinogens," MacAllister said. "This results in more carcinogens (致癌物质) reaching the lungs." Birds are also at risk for lung cancer,as well as pneumonia,because their respiratory systems are hypersensitive to any type of air pollutant. To help prevent animals from being adversely affected by smoking,pet owners who smoke should have a designated smoking area that is separated from the home or stop smoking altogether,MacAllister said. |
1. From the passage,we can see secondhand smoke maybe not harmful to _______. |
A. smokers B. non-smokers C. pets D. trees |
2. What can be suggested according to the passage? |
A. Smokers can smoke anywhere. B. Smokers can smoke at any time. C. Smokers should smoke in the designated place. D. Smokers must give up smoking at once. |
3. What kind of dogs are likely to suffer from nasal cancer? |
A. Long-nosed dogs B. Short-nosed dogs C. Medium-nosed dogs D. Dogs without noses |
4. The best title of the passage is __________. |
A. Secondhand Smoke Causes Cancer in People B. Secondhand Smoke Causes Cancer in Birds C. Secondhand Smoke Causes Cancer in Pets D. Secondhand Smoke Causes Cancer in Cats |
5. What is the meaning of the underlined phrase "are susceptible to"? |
A. are likely to be harmed by B. are hard to be influenced by C. are less to be effected by D. are lucky to be caught by |
