1、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth's surface. That's why methane is a major contributor to the planet's increasing temperature rise or global warming. Molecule for molecule, methane's heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it's no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth's atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun's heat and warm the planet, life as we know it couldn't exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn't live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It's part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That's why we say livestock gas is also a major factor of causing the global warming.Greenhouse gases are indispensable to mankind, but the problem mankind is faced with is ____ .【单选题】

A.one of tire major contributors

B.the ever-increasing atmospheric concentration of greenhouse gases

C.big and hefty cows

D.livestock's normal digestion process

E.how to cut down the cattle population

F.big industries and gas-guzzling vehicles

正确答案:B

答案解析:选B的依据在第3段的第2句、第3句和第4段的第1句。这三个句子先后介绍了下列观点：没有温室气体，生物不能生存；人类燃烧能源，加剧温室效应；大气甲烷的含量增加一倍。

2、Geology and Heap(1)The importance of particular metals in the human diet has been realized within the past few decades, and the idea that geology might be related to health has been recognized for a number of elements such as iodine, zinc and selenium. For example, soils with low iodine contents produce crops, and animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth. The water we drink contains trace elements leached from rock and soil. Thus the geology and geochemistry of the environment have effects on the chemistry and health of plants, animals and people.(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies and rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans and above environmental quality criteria.(6)There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body. Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.Paragraph 3 ______【单选题】

A.No Evidence to Indicate Bad of Naturally Contaminated Soil

B.Potential Hazards of Human Contaminated Soils

C.Research an Channels of Heavy Metals Getting into Human Food Chain

D.Geology and Health Problems

E.Rocks----the Ultimate Source of Soil Pollution

F.Long-term Health Effects on Children

正确答案:A

答案解析:第3段谈及的是自然污染的土壤一般情况下对人体不会造成危害。此段首句就提示了这一点： So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard.

3、Operatunity1. Operatunity is a TV talent show for amateur opera singers, The winners get the chance to sing with the English National Opera. When two housewives, Denise Leigh and Jane Gilchrist won in 2002, their lives changed forever, As they sang Verdi's Rigoletto at the Coliseum (音乐厅) in Rome, they were transformed from working mothers into opera celebrities (名人).2. "I live in the village I was born in," says Denise, who is blind. "Lots of my neighbours are family, and my life is all about my three children. Jane, who worked as a cleaner and a shop assistant, was in a similar situation." She says. All I had to look forward to was seeing my four children grow up, and I love them, but ... you know there must be more things than life. Winning Operatunity has opened up avenues I never knew existed."3. "Last year was amazing," Denise continues, "Last month was Paris, before that we were recording at Abbey Road, in London, and recently we had our album launch at the Royal Opera House" "We've been treated like princesses," laughs Jane, "... champagne, chocolates, five - star hotels ..."4. But it wasn't all so easy. For Denise, the worst part was waiting at the beginning. "After I'd sent in my application form I worried for a month, Then I had to wait ten days after my first audition (试唱). That was awful." Even when they won the competition they were allowed to tell their close family but they weren't allowed to tell anyone else until later. Denise and Jane also found the travelling is difficult. They couldn’t take their children with them while they were away singing, so they had to organise childcare. However, there's been no problem with the physical side of singing: "We didn't have to worry about that as we've had lots of help and wonderful voice training." says Jane. They also had to learn to deal with the media." The kids loved the fact that they could stay up and watch us on TV, but I just couldn't understand why some newspapers were more interested in the fact I divorced at 21, rather than the fact I had just sung at the Coliseum, says Denise.Paragraph 4 ____【单选题】

A.Advice

B.Living the new life

C.The competition

D.Becoming famous

E.Their lives before

F.The difficult parts

正确答案:F

4、Ceasing to Wear TiesIt's useless. It's dirty. It spreads disease. That's why the British Medical Association in the UK recently called for hospital doctors to stop wearing ties.That leads to another question. Why does anyone wear a tie? Ties serve no purpose. They do not cover any part of your body and keep you warm. They always seem to get covered in food stains. Perhaps that is the purpose of the tie. It lets everyone know what you just ate.Ties have an odd history. Soldiers from Croatia, in Eastern Europe, served as mercenaries (雇佣军) in various conflicts in the 17th century. They were identified by brightly colored pieces of silk worn around the neck. Known as cravats(围巾), these became a popular fashion item in France and eventually evolved into the tie.It's an interesting story, but it doesn't tell us why men want to put useless pieces of cloth or silk around their necks. The answer seems to be about identification(身份证明 ). In the 19th-century Britain, ties were used by universities, military regiments (团), sports clubs, schools and gentleman's clubs. Each tie was in a particular set of colors which identified the wearer as a member of that organization. Wearing ties was also the mark of Britain's most powerful classes. That made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger class-the business class.You cannot wear a tie if you work with machinery, so wearing a tie became a sign that you were a man who used his brain to make a living, rather than his hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who did not wear a piece of colored silk around his neck. This is how millions of people came to wear ties across the world.Is there a future for ties? The signs are not promising. Many political leaders, including British Prime Minister Tony Blair, now go without ties.The British Medical Association suggested that________.【单选题】

A.they were workmen

B.they were members of different organizations

C.hospital doctors stop wearing ties

D.who does not always wear a tie

E.who served as mercenaries in many conflicts in the 17th century

F.who does not want to live like a king

正确答案:C

答案解析:根据题干中的线索词British Medical Association可定位到第一段最后一句：That's why the British Medical Association in the UK recently called for hospital doctors to stop wearing ties.选项C与其表达吻合，是原文的原意复现，故C为正确答案。

5、Money or Friendship or Both1. Friends and money don't mix. It's a dangerous combination since a fight over money is one of the fastest ways to end a friendship. But what if a friend asks you to tend him or her some money? If you don't lend your friend the money, you risk losing the friend. If you do lend your friend the money, you risk losing both the friendship and your money.2. We have to face facts, so here are some situations you might run across with your buddies (伙伴) and some helpful tips (忠告) on how to deal with them. Thinking about why this person needs to borrow in the first place. If he is always living beyond his means, it is his fault, not yours. Any Sensible person would not put himself in a position of debt so often. So simply say "no" to this friend. Even if your friend really needs that money for emergency use and you are willing to help him, before you dive into your pocket, follow this reality check: Do you have the extra money? Are you sure you don't need it? Are you willing to write off that amount if it's not returned? If your answers are negative, do yourself a favor and say "no".3. Let's assume you can't stand saying "no" to your friend because you don't want him living off cat food. What do you do? Write down these details on a sheet of paper before opening up your wallet:Amount of the loan.Date of the loan.Time of repayment.Amount of interest (if any).Lender's and borrower's signature.This will at least keep the borrower from forgetting the loan so easily, If your friend's loan is past due, it's important that you ask him－and it's actually not rude. The longer you wait, the more you are brood (忧伤), and the more your resentment builds.4. You can send him a friendly reminder via E - mail. Tell him something like "I'm going over my bank account and I'm just wondering when we'll be able to settle that money thing." E - mail saves you from an uncomfortable face - to - face confrontation. There is almost no chance of turning a bad reaction into an argument. Unlike a public conversation, an E - mail message will always be private.5. After asking two or three times, you might have to write it off. That's what happens. If he just doesn't have the money or is unwilling, then what kind of friend is that?Paragraph 5 ____【单选题】

A.Time to Break off a Friendship

B.Unconditional Assistance to Friends in Need

C.Things to Consider When You Have to Say "No" to Your Friend

D.Things to Think over When You Don't Want Your Friend to Eat Cat Food

E.Strategies for Borrowing Money

F.Advantages of E - mail in Handling Money Issues

正确答案:A

答案解析:本题难度不大，主旨句比较好确认，就是第五段的第一句。第五段主要谈到在询问朋友两三次后，还没有结果时，就要考虑结束你们的友谊。回来看选项，A选项Time to Break off a Friendship，言简意赅地概括本段意思了，是答案。
