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、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?Before you lend money to your friend ____.【单选题】

A.you can remind your friend of it via E - mail

B.you can lend more money to him or her

C.you must get to know why he or she needs that money

D.if you should lend money to your friend

4、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.Some serious diseases is connected with deficiency of ____【单选题】

A.industrially polluted soils

B.rock and soil chemistry

C.naturally polluted soils

D.the pathways of metals into the food chain

E.the element of iodine

F.the persistence of heavy metals

正确答案:E

答案解析:第1段最后一句“A lack of iodine in the human diet leads to some serious diseases”是选择E的依据。

5、Continuing Education1 People around the world agree that education is not an end, but a means to an end. In other words, we do not educate students only for the aim of educating them. Our purpose is to fit them for life. Life is varied; so is education.2 Ideas about education are more specified in the United States. Education today is not just a high school diploma or a college degree. Many adults are not interested in going to college. They are interested in other kinds of learning. For them, learning does not end with a diploma.3 Continuing education gives these adults the opportunity to increase their knowledge about their own field or to learn about a new field. It also gives them a chance to improve their old skills or to learn new ones. Scientists, mechanics, secretaries, barbers and cooks can take classes to improve their work skills. If they know more or learn more, they can get a better job or earn more money.4 Continuing education classes give more adults the chance to learn new skills. There is usually a large variety of classes to choose from: typing, foreign cooking, photography, auto repair, furniture repair, or swimming. There are only some of the classes available.5 Some adults take classes for fun or because the class will be useful for them. Other adults take continuing education classes to improve their own lives because they want to feel better about themselves.6 Almost any community college or public school system has a continuing education program. There are classes in schools, community buildings or churches. Most classes are in the evenings, so working people can attend. The classes are usually small, and they are inexpensive.Paragraph 4 ____【单选题】

A.Ideas bout education in the U. S.

B.Advantages of continuing education

C.Good opportunity to learn new skills

D.Most classes are in the evening

E.Working people have easy access

F.Education helps cooks find a better job

正确答案:C

答案解析:段首句即该段的主题句。Continuing education classes give more adult the chance to learn new skill，所以答案是C。
