1、Don\'t Rely on Plankton to Save the PlanetEncouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. Its opponents fear that will damage the marine ecosystem, ａｎｄ　now a computer model shows that the trick would also be remarkably inefficient.Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. ______Jorge Sarmiento from Princeton ａｎｄ　his colleagues developed a complex computer model to analyze how factors such as ocean chemistry ａｎｄ　water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron fｏｒa month. They found that 100 years later only between 2 ａｎｄ　13 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results."These are newer ａｎｄ　better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."Butthe take-home message is the same. Ocean fertilization is not the answer to global warming."【单选题】

A.Its opponents argue, however, that it will stop global warming.

C.As plankton die ａｎｄ　settle on the ocean floor, their carbon is supposedly locked up in the seabed.

D.They found that 100 years later only between 2 ａｎｄ　12 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.

E."These are newer ａｎｄ　better models,"

F.Ocean fertilization is not the answer to global warming.

2、Keeping Cut Flowers1 While everybody enjoys fresh cut flowers around his house, few people know how to keep them fｏｒas long as possible. This may be done by keeping in mind a few simple fact. 2 An important thing to remember about cut flowers is that they are sensitive to temperature. Fｏｒexample, studies have shown that cut carnations (康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care. 3 Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds ｏｒinsects, such as bees, fｏｒpollination (粉). After that, they quickly dry up ａｎｄ　die. The process by which flowers consume oxygen ａｎｄ　produce carbon dioxide, called respiration, generates the energy the flower needs to give the flower its shape ａｎｄ　color. The making of seeds also depends on this energy. While all giving things respire, flowers have a high level of respiration. A result of all this respiration is heat, ａｎｄ　fｏｒflowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies. 4 How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced ａｎｄ　the cut flower will age more slowly. 5 Another vital factｏｒin keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to "drink" water that is dirty ｏｒotherwise polluted. Even when water looks ａｎｄ　smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach (at 4% solution) be added to each liter of water. The water ａｎｄ　solution should also be replaced each day. Paragraph 2____【单选题】

A.Control of Respiration

B.Beauty of Fresh Cut Flowers

C.Role of Respiration

D.Most Important Aspect of Flower Care

E.Need fｏｒClean Water

F.Ways of Stopping Respiration

正确答案:D

答案解析:本段第1句和最后一句都是该段的主题句，但是最后一句是此题的答案，选项D几乎是最后一句的原句重现，故选D。

3、They agreed to settle the dispute by peaceful means. 【单选题】

4、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.Most of the flesh water on Earth ______.【单选题】

A.is stored underground

B.is in the form of ice at the Poles ａｎｄ　on mountains

C.is found in rivers ａｎｄ　lakes

D.comes from the rain

正确答案:B

答案解析:本题有一定难度，需要认真读懂文章句意，答案依据比较明显，在文章第二段第四句，谈到剩下1/3的淡水以冰的形式存在在南北两极和高山上，回来看选项，B项是其近义解释，所以正确，答案是B。

5、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. This passage is mainly about____. 【单选题】

A.the meaning of a budget

B.the relation between budget ａｎｄ　income

C.the way in which a budget is made

D.the importance of making a budget

正确答案:C

答案解析:本文从预算的作用开始引入，到第2段开始分步骤地介绍了进行预算的方式，主要讲的是进行预算的方法问题。

6、Better Control of TB Seen if a Faster Cure is FoundThe World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS ａｎｄ　drug-resistant forms of tuberculosis. Current treatments take at least six months. Patients have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure fｏｒtuberculosis would be more effective. Now a study estimates just how effective it might be. A professｏｒof international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean ______ infectious patients who can pass on their infection to others. The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. ａｎｄ　it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousａｎｄ　twelve ａｎｄ　two thousａｎｄ　thirty. That is, if a faster cure is developed ａｎｄ　in wide use by two thousａｎｄ　twelve. The World Health Organization developed the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment. Earlier this year, an international partnership of organizations announced a plan to expａｎｄ　the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance fｏｒTB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.【单选题】

A.many

B.more

C.few

D.fewer

正确答案:D

答案解析:前句说到更多病人可以被治愈，根据推理，后句应该是“将感染传递给别人的传染病人就会更少”，因为前后两句实际上具有因果关系。这里必须用比较级fewer，因为few是表示“不多的，几乎没有的(=not many)”，而fewer则只是与以前比较“更少”，并没有明确多少。

7、Weaving 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 is 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 off light 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.The Huichol don\'t use electricity because ______. 【单选题】

A.it is too difficult fｏｒthem to change their lifestyle

B.they know nothing about it

C.it costs too much to string power lines

D.they don\'t need it

正确答案:C

答案解析:本题有一定难度，关键在吃透句意，答案依据比较明显，带着题干信息词回文章定位，答案依据主要在文章第一段第二句：That\'s because it\'s too expensive to string power lines to the remote mountain areas where they live．谈到将电力设施铺设到山里投资巨大，string是引申意义，此处是“铺设”的意思，回来看选项，C项和原文句意相符，答案是C。

8、Seeing Red Means Danger AheadThe colｏｒred often means danger ａｎｄ　by paying attention, accidents can be prevented. In the future, the colｏｒred also may help _____ danger at construction sites. Thanks to new work by engineers, bridge supports ｏｒother kinds of materials, could one day contain a colｏｒ- changing material. It will turn red before a structure collapses ｏｒfalls apart.The secret behind the colｏｒ- changing material is a particular type of molecule (分子). A molecule is aｇｒｏｕｐof atoms (原子) held together by chemical bonds. Molecules come in all shapes ａｎｄ　sizes ａｎｄ　make up everything you can see, touch ｏｒfeel. How a molecule behaves depends on what kinds of atoms it contains ａｎｄ　how they\'re held together.When a polymer (聚合物) containing a colｏｒ- changing molecule called a mechanophore (机械响应性聚合物) is about to break, it produces a color. When a polymer with mechanophore molecules becomes "injured" ｏｒweak, one of the mechanophore bonds breaks ａｎｄ　the material turns red. "It\'s a really simple detection method," says Nancy Sottos, one of the scientists who worked on the project. Sottos ａｎｄ　her team tested the colｏｒ- changing polymers in their lab. The test results proved encouraging.There is a way to get rid of the red colｏｒlight. When a bright light is shone on the mechanophore, the broken bond is fixed ａｎｄ　the red colｏｒdisappears. Thus "self - healing" may be a problem fｏｒengineers. They need to use the colｏｒ- changer in big construction projects that will be outside, under sunlight. ａｎｄ　sunlight will make the mechanophore\'s warning system useless.Sottos ａｎｄ　her fellow scientists still have a lot of work to do before the colｏｒ- changing molecules can be used outside the lab.【单选题】
