1、WaterThe second most important constituent (构成成份) of the biosphere (生物圈) is liquid water. This can only exist in a very narrow range of temperatures, since water freezes at 0℃ ａｎｄ　boils at 100℃. Life as we know it would only be possible on the surface of a planet which had temperatures somewhere within this narrow range.The earth\'s supply of water probably remains fairly constant in quantity. The total quantity of water is not known very accurately, but it is about enough to cover the surface of the globe to a depth of about two ａｎｄ　three - quarter kilometers. Most of it is in the form of the salt water of the oceans about 97 percent. The rest is fresh, but three -quarters of this is in the form of ice at the Poles ａｎｄ　on mountains, ａｎｄ　cannot be used by living systems until melted. Of the remaining fraction, which is somewhat less than one percent of the whole, there is 10 -20 times as much stored underground water as there is actually on the surface. There is also a tiny, but extremely important fraction of the water supply which is present as water vapour in the atmosphere.Water vapour in the atmosphere is the channel through which the whole water circulation (循环) of the biosphere has to pass. Water evaporated (蒸发) from the surface of the oceans, from lakes ａｎｄ　rivers ａｎｄ　from moist (潮湿的) earth is added to it. From it the water comes out again as rain ｏｒsnow, falling on either the sea ｏｒthe land. There is, as might be expected, a more intensive evaporation per unit area over the sea ａｎｄ　oceans than over the land, but there is more rainfall over the lａｎｄ　than over the oceans ａｎｄ　the balance is restored by the runoff from the lａｎｄ　in the form of rivers.Liquid water only exists ______.【单选题】

A.in the center of the earth

B.on the surface of our planet

C.in a very narrow range of temperatures

D.in the coastal areas of the earth

正确答案:C

答案解析:本题难度不大，答案依据比较明显，答案依据是文章第一段第二句，谈到液态水只存在于很小的温度范围内（零度到一百度），回来看选项，C项是其近义解释，所以正确，答案是C。

2、Genetically Modified FoodEuropean ｕｎｉｏｎenvironmental officials have determined that two kinds of genetically modified corn could harm butterflies, affect food chains ａｎｄ　disturb life in rivers ａｎｄ　streams, ａｎｄ　they have proposed a ban on the sale of the seeds, which are made by Dupont Pioneer, Dow Agrosciences ａｎｄ　Syngenta. The preliminary decisions are circulating within the European Commission, which has the final say. Some officials there are skeptical of a ban that would upｓｅｔthe powerful biotechnology industry ａｎｄ　could exacerbate tensions with important trading partners like the United States. The seeds are not available on the European market fｏｒcultivation.In the decisions, the environment commissioner, Stavros Dimas, contends that the genetically modified corn, ｏｒmaize could affect certain butterfly species, specifically the monarch, ａｎｄ　other beneficial insects. Fｏｒinstance, research this year indicates that larvae of the monarch butterfly exposed to the genetically modified corn "behave differently than other larvae." In the decision concerning the corn seeds produced by Dow ａｎｄ　Pioneer, Mr. Dimas calls "potential damage on the environment irreversible." In the decision on Syngenta\'s corn, he says that "the level of risk generated by the cultivation of this product fｏｒthe environment is unacceptable."A decision by the European ｕｎｉｏｎto bar cultivation of the genetically modified crops would be the first of its kind in the trade bloc, ａｎｄ　would intensify the continuing battle over genetically modified corn. Banning the applications fｏｒcorn crops also would mark a bold new step fｏｒEuropean environmental authorities, who are already aggressively pursuing regulations on emissions from cars ａｎｄ　aircraft, setting it at odds with the United States ａｎｄ　angering industries."These products have been grown in the U. S. ａｎｄ　other countries fｏｒyears," said Stephen Norton, a spokesman fｏｒthe United States trade representative. "We are not aware of any other case when a product has been rejected after having been reviewed ａｎｄ　determined safe by European food safety authorities," he said.Barbara Helfferich, a spokeswoman fｏｒMr. Dimas, declined to comment on the specifics of the procedure because commissioners had not yet made a final decision. But she said that the European ｕｎｉｏｎwas within its rights to make decisions based on the "precautionary principle" even when scientists had found no definitive evidence proving products can cause harm. She said that the decisions by Mr. Dimas could go before the commission within a few weeks, but she said that no date had been set. In the decisions, Mr. Dimas cited recent research showing that consumption of genetically modified corn byproducts reduced growth ａｎｄ　increased mortality of non-target stream insects ａｎｄ　that these insects are important prey fｏｒaquatic ａｎｄ　riparian predators ａｎｄ　that this could have unexpected ecosystem-scale consequences."Although still preliminary, his decisions could drastically tilt the policy against future approvals of genetically modified crops," said Nathalie Moll, a spokeswoman fｏｒEuropabio, an industryｇｒｏｕｐwith 80 members including Syngenta, Pioneer ａｎｄ　Dow. Europabio says that the crops grown using the genetically modified corn are already imported into several European countries, including France ａｎｄ　Germany, where they are used to feed animals like cows ａｎｄ　chickens.Rob Gianfranceschi, spokesman at the United States mission to the European ｕｎｉｏｎin Brussels, said it was too early to comment on a decision that had not yet been formalized. But he made clear that the United States remained frustrated with European policies on genetically modified crops.To the decisions, the European Commission officials\' attitudes are ______.【单选题】

A.skeptical

B.controversial

C.contradictory

D.divergent

正确答案:D

答案解析:态度题。题干考查的是欧洲委员会官员对于这些决议的态度。文中表示一些官员对禁令表示怀疑，主要害怕禁令会影响外交关系；而一些官员表示支持，可见这些官员所持的态度是有分歧的。考生可能会受到选项B的干扰，比较看来，选项D更为精确。

3、BudgetA budget is a spending plan. It can help you spend money wisely. It can do this by cutting out wasteful spending. Of course, preparing a budget takes planning, ａｎｄ　following a budget takes will power. Your budget should meet your family\'s needs ａｎｄ　income. The first step in creating a budget is to ｓｅｔyour goals. What does your family need ａｎｄ　wants. You must know this to work out the details of the budget. Keep goals realistic, in terms of income available. Then decide which goals are the most important. The next step is estimating family income. Before you can plan wisely, you need to know how much money you have to spend! Write down all the money you expect to receive (wages, savings, interest, etc.) during the planned budget period. After you have calculated how much money will be available, it is time to estimate expenses. List all of your family expenses. If you are not satisfied with what you got fｏｒyour money, look carefully at your spending. Studying your records will show where overspending has occurred. It will also point out poｏｒbuying habits. It is also a good idea to ｓｅｔaside a small amount of money fｏｒemergencies. Every family has small emergencies: a blown tire, a broken device, ｏｒthe need fｏｒminｏｒmedical care. One advantage of keeping a record of your spending is that____. 【单选题】

A.you will remember how much you have already spent

B.you will know if you have spent more money than you planned

C.you will be able to tell your family what should not be bought

D.you will learn how to make a better budget next time

正确答案:B

答案解析:第5段讲了“Studying your records will show where overspending has occurred. It will also point out poｏｒbuying habits”（消费记录可以找出哪里超支了，或者可以发现一些不良购买习惯）。所以B是正确答案。

4、Waving With LightIn the Sierra Madre mountain range of west central Mexico, the native Huichol people live much the way their ancestors did without electricity. That\'s because it\'s too expensive to string power lines to the remote mountain areas where they live. To help support themselves, the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. ａｎｄ　without electricity at home ｏｒon the road, they can only work during daylight hours. When it gets dark, they must stop whatever they\'re doing. Now, a team of scientists, designers, ａｎｄ　architects are using new technologies to provide the Huichol with light after the sun sets. The scientists\' technique involves weaving tiny electronic crystals into fabrics that can be made into clothes, bags, ｏｒother items. By collecting the sun\'s energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics "Portable Lights." Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy. "Our invention," Kennedy says, "came from seeing how we could transform technology we saw every day in the United States ａｎｄ　move it into new markets fｏｒpeople who didn\'t have a lot of money."At the core of Portable Light technology are devices called high-brightness light-emitting diodes, ｏｒHB LEDs. These tiny lights appear in digital clocks, televisions, ａｎｄ　streetlights. LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give of flight we can see. Ninety percent of energy produced by incandescent lights, however, is heat ａｎｄ　invisible. With all that wasted energy, bulbs burn out quickly. They are also easily broken. LEDs, on the other hand, are like tiny pieces of rock made up of molecules that are arranged in a crystal structure. When an electric current passes through an LED, the crystal structure produces light. Unlike incandescent bulbs, they can produce light of various colors. Within an LED, the type of molecules ａｎｄ　their particular arrangement determines what colｏｒis produced. Why can Portable Lights emit light?【单选题】

A.Electronic crystals are woven into fabrics.

B.Items such as clothes ａｎｄ　bags are used to carry lights.

C.The sun\'s energy is collected during the day.

D.All of the above.

正确答案:D

答案解析:文章的第2段和第3段包括了选项A、B和C所述内容。所以答案是D。

5、Dairy Price-fixing ScandalTesco is preparing a legal battle to clear its name of involvement in the dairy price-fixing scandal that has cost consumers ￡270 million. Failure to prove that it had no part in collusion with other supermarkets ａｎｄ　dairy processors may lａｎｄ　it with a fine of at least ￡80 million. The Office of Fair Trading (OFT) said yesterday that Asda, Sainsbury\'s ａｎｄ　the former Safeway, plus the dairy companies Wiseman, Dairy Crest ａｎｄ　Cheese Company, had admitted being in a cartel to fix prices fｏｒmilk, butter ａｎｄ　cheese. They were fined a total of just over ￡116 million as part of a leniency deal offered by the watchdog to companies that owned up quickly to anti-competitive behaviour.Officials at the OFT admitted privately that they did not think they would ever discover which company ｏｒindividual had initiated the pricing formula. But the watchdog recognises that at the time supermarkets were under pressure from politicians ａｎｄ　farmers to raise the cost of milk to save dairy farming, though it is not certain that money found its way to farmers. The OFT claimed in September that it had found evidence that the retail chains had passed future milk prices to dairy companies, which then reached a fixed price among themselves.The average cost to each household is thought to be ￡11.25 over 2002 ａｎｄ　2003, Prices went up an extra 3p on a pint of milk, 15p on a quarter of a pound of butter ａｎｄ　15p on a half pound of cheese. There is no direct recompense fｏｒconsumers, however, ａｎｄ　the money will go to the Treasury. The National Consumer Council gave warning that the admissions would dent consumer confidence in leading high street names ａｎｄ　that people would become sceptical of their claims. Farmers fｏｒAction, theｇｒｏｕｐof farmers that has led protests over low milk prices since 2000, is seeking legal advice on whether it can now bring a claim fｏｒcompensation.The OFT investigation is continuing, however, in relation to Tesco, Morrisons ａｎｄ　the dairyｇｒｏｕｐLactalis McLelland, ａｎｄ　any legal action is expected to be delayed until that is completed. Tesco was defiant ａｎｄ　said that it was preparing a robust defence of its actions. Lucy Neville-Rolfe, its executive director, said: "As we have always said, we acted independently ａｎｄ　we did not collude with anyone. Our position is different from our competitors ａｎｄ　we are defending our own case vigorously. Our philosophy is to give a good deal to customers."Morrisons has supported the OFT in inquiries into the former safeway business that it took over, but in a statement said that it was still making "strong representations" in its defence. A spokeswoman fｏｒLactalis McLellａｎｄ　said that the company was "co-operating" with the OFT. Industry insiders suggested that the three companies were deliberately stalling the OFT investigation.Sainsbury\'s admitted yesterday that it had agreed to pay ￡26 million in fines, but denied that it had sought to profiteer. Justin King, the chief executive, said he was disappointed that the company had been penalised fｏｒactions meant to help farmers but recognised the benefit of a speedy settlement. Asda declined to say how much it would pay in fines ａｎｄ　also said that its intention had been to help farmers under severe financial pressure.From the first paragraph, we may infer that ______.【单选题】

A.Tesco has cost consumers ￡270 million

B.Tesco has colluded with Asda, Wiseman, Dairy Crest ａｎｄ　Cheese Company in fixing the dairy price

C.Tesco will be offered a leniency deal of 80 million

D.Tesco is trying its best to prove its innocence of the scandal

正确答案:D

答案解析:推理题。第一段主要讲述了Tesco公司已被卷入和其他公司联手划定牛奶价格的丑闻中，目前正在通过法律手段证明自己与此无关。因此选项D，Tesco正在竭力证明自己和丑闻无关，符合题意，故正确答案为D。
