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.Generally people heap criticism on fox the planet\'s temperature rise ____ .【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:F

答案解析:第4段第2句直接谈到这个问题，人们常常将不断加剧的温室效应归罪于大工业和汽车，而cattle释放甲烷的因素被忽略了。

2、RobotsThe most sophisticated (先进的) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接), spray-painting and assembling components.In Britain robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan. The reliability of robots is measured in their MTBF or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small .sample.The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. One programmed robots can work more accurately and consistently than humans, who can get tired and bored.Paragraph 6 ________.【单选题】

A.Ongoing Research

B.Extension of Use

C.Robot Heroes

D.Greater Reliability

E.Falling Demand

F.Hidden Danger

正确答案:D

答案解析:第六段没有主题句，该段主要提到了提升机器人可靠性的方法。D选项Greater Reliability（更高的可靠性）与其表达一致，故D为正确答案。

3、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.Geologists are indispensable in the research project on geology and health due to their knowledge on ____ .【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:B

答案解析:全文都在论述重金属的摄入可能会对人体健康产生有害影响，最后一段说到地质学家在解决调查这个问题能起的作用。这个句子是：Geologists should be part of such studies as they can provide the essential background information on rock and sail chemistry as well as the chemical forms of heavy metal pollution.

4、Intelligent Machines1. Medical scientists are already putting computer chips (芯片) directly into the brain to help people who have Parkinson\'s disease, but in what other ways might computer technology be able to help us? Ray Kurzweil is author of the successful book The Age of Intelligent Machines and is one of the world\'s best computer research scientists. He is researching the possibilities.2. Kurzweil gets computers to recognize voices. An example of this is Ramona; the virtual (虚拟的) hostess of Kurzweil\'s homepage, who is programmed to understand what you say. Visitors to the site can have their conversations with her, and Ramona also dances and sings.3. Kurzweil uses this technology to help people with physical disabilities. One of his ideas is a "seeing machine". This will be "like a friend that could describe what is going on in the visible world", he explains. Blind people will use a visual sensor (探测器) which will probably be built into a pair of sunglasses. This sensor will describe to the person everything it sees.4. Another idea, which is likely to help deaf people, is the "listening machine". This invention will recognize millions of words and understand any speaker. The listening machine will also be able to trans late into other languages, so even people without hearing problems are likely to be interested in using it.5. But it is not just about helping people with disabilities. Looking further into the future, Kurzweil sees a time when we will be able to download our entire consciousness onto a computer. This technology probably won\'t be ready for at least 50 years, but when it arrives, it means our minds will be able to live forever.Paragraph 5 ____【单选题】

A.A new pair of eyes

B.Computers that can communicate

C.Everlasting consciousness on a computer

D.Time to break off a friendship

E.An author and researcher

F.A new pair of ears

正确答案:C

答案解析:本题有一定难度，没有明显的主旨句。但第五段中间的关键词汇consciousness onto a computer，选项有近义解释。本段主要是畅想未来，谈论人类的整个意识系统可能会被植入到电脑里面，这样就意味着人类思想可永远留存。C项Everlasting consciousness on a computer，“在电脑里永远留存的意识”，可以概括本段内容，答案是C。

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?Sometimes you may find it very difficult to decide ____.【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

E.you can call the police to settle the issue

F.there is no need to maintain a friendly relation with him or her
