2、Ants as a Barometer of Ecological ChangeAt picnics, ants are pests. But they have their uses. In industries such as training, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.It has been recognized for decades that ants-which are highly sensitive to ecological change can provide a near-perfect barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. Others will die out for lack of food. And still others will move in and take up residence.By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys. Ants are used simply because they are so common and comprise so many species.Where mine sites are being restored, for example, some ant species will recognize the stripped land more quickly than others. This allowed scientists to gauge the pace and progress of the ecological recovery. Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.Ant surveys also have been used with mine-site recovery projects in Africa and Brazil, where warm climates encourage dense and diverse ant populations. "We found it worked extremely well there," says Jonathan Majer, a professor of environmental biology. Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region. As Majer puts it: "That\'s the great thing about ants. "Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. ______.Why not? Because many companies can\'t afford the expense or the laboratory time needed to sift results for a comprehensive survey. The cost stems, also, from the scarcity of ant specialists. Employing those people are expensive. 【单选题】

A.This allowed scientists to gauge the pace and progress of the ecological recovery.

B.Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.

C.Employing those people are expensive.

D.They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.

E.The evolution of ant species may have a strong impact on our ecosystem.

F.Others will die out for lack of food.

正确答案:B

答案解析:选项B中的关键词other businesses、farming、property提示，选项B的句子是前面句子的后续句，因为前面句子有mining、tree harvesting，也是businesses。蚂蚁分析法已被 mining和tree harvesting等行业广泛接受，但在farming和property行业中的应用还不普遍。

3、The State of Marriage TodayIs there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, and the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times and extramarital affairs will be even more common than they are now.But what are the reasons for this, and is the picture really so gloomy? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based for years partly on economic need. Women used to be economically dependent on their husbands as they usually didn\'t have jobs outside the home. But with the rising number of women in well-paying jobs, this is no longer the case, so they don\'t feel that they need to stay in a failing marriage.In answer to the second question, the outlook may not be as pessimistic as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now cohabit and don\'t bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive. The statistics are deceptive because there is a higher number of divorces in second and third marriages than in first marriages.So is marriage really an outdated institution? The fact that most people still get married indicates that it isn\'t. And it is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences, such as heart problems, and married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!Which is true about the problem of marriage in the United States today?【单选题】

A.Divorce leads to the breakup of the family.

B.Half of the married couples get divorced.

C.American people marry more than four times.

D.More and more people are getting divorced.

正确答案:D

答案解析:从第1段里可以了解到选项A与C都是预计将来会发生的，而不是如今的情况。B选项与第1段第2句“almost 50% of the marriages end in divorce”不符。第1段第2句里的“the rate of divorce in the United States has exploded”、“the evidence suggests it is going to get worse”正好说明了D选项的情况。

4、Don\'t get upset about trivial matters.【单选题】

5、Michael is now merely a good friend.【单选题】

A.largely

B.possibly

C.just

D.rarely

正确答案:C

答案解析:merely和just的含义相同，表示“仅仅”；largely:大部分、主要；possibly:可能地； rarely:几乎不。

6、A Glass of MilkOne day, a poor boy who was trying to pay his way through school by selling goods door to door found that he only had one dime left. He was hungry so he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, "How much do I owe you?""You don\'t owe me anything," she replied. "Mother has taught me never to accept pay for a kindness," he said, "Then I thank you from the bottom of my heart. " As Howard Kelly left that house, he not only felt stronger physically, but also increased his faith in God and the human race. He was about to give up and quit before this point.Years later the young woman became critically ill. The local doctors were baffled. They finally sent her to the big city, where specialists can be called in to study her rare disease. Dr. Howard Kelly, now famous was called in for the consultation. When he heard the name of the town she came from, a strange light filled his eyes. Immediately, he rose and went down through the hospital hall into her room.Dressed in his doctor\'s gown he went in to see her. He recognized her at once. He went back to the consultation room and determined to do his best to save her life. From that day on, he gave special attention to her case.After a long struggle, the battle was won. Dr. Kelly requested the business office to pass the final bill to him for approval. He looked at it and then wrote something on the side. The bill was sent to her room. She was afraid to open it because she was positive that it would take the rest of her life to pay it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words. . ."Paid in full with a glass of milk," signed Dr. Howard KellyTears of joy flooded her eyes as she prayed silently: "Thank You, God.

7、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。

8、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight or shade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your _____. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein\'s calculations helped him theorize would behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】

A.education

B.status

C.knowledge

D.location

正确答案:D

答案解析:整个宇宙空间的温度是多少度呢？温度的高低取决于哪个因素呢？从四个选项分析：温度不会取决于你的education（教育）、你的status（地位）或你的knowledge（知识），因为这不合乎逻辑。只有选location（位置）才符合上下文的意思。

9、Life at Aichi UniversityI\'m Yamamoto Mika, a 22 years old Japanese girl. I\'d like to invite you to Aichi University so you can understand my life.Our university has a close relationship with China and my department is the only one of its kind in Japan. My courses include the Chinese language, modern Chinese politics and economics. I love Chinese culture and I have been to Tianjin as an exchange student.In Japan, our courses are divided into compulsory, optional and specialized courses. However, we have a flexible schedule. We can choose classes from a wide range of options.Many students finish the compulsory courses in three years so that they can have one year without any classes. They often use this period of time to study abroad, conduct research and travel. Many students even suspend their study for additional study - abroad opportunities,Japanese universities encourage students to choose their own ways of study, so it is quite easy for us to apply for study suspension.Japanese students participate in various kinds of extracurricular (课外的) activities. They attend clubs from elementary schools, so many students have already been accustomed to clubs when they enter university.Our university now has 42 art clubs and 45 sports clubs. The annual University Festival is the grandest carnival (狂欢节) of Japanese universities. In the festival, students promote their clubs and organize various activities. Our university\'s festival attracted about 150,000 people last year. I really like this festival.When we promote our clubs, we cook "tonnjiru", a kind of pork soup, and sell it to other students at the fair.We also go to different places to interview celebrities (名人) who attend our festival as guests. It is a wonderful experience to talk to those stars face to face.Japanese students like to hold parties. We have two kinds of parties. One is the Mochivori party. If you want to attend this party you have to cook something and take it to the party. The organizer buys drinks and snacks.The other kind of party is the Nomikai, which mainly involves alcohol. We drink something called chu - hai, which is a combination of soda and wine. We also drink Japanese sake (日本米酒) and beer. There are parties for many occasions, like welcoming new students, celebrating victories and birthday parties or just for promoting friendship.The word "compulsory" in paragraph 3 could be best replaced by ____.【单选题】

A.required

B.forced

C.requested

D.demanded

正确答案:A

答案解析:本题有一定难度，考查的是单词的基本意义，但干扰项有一定的干扰性。compulsory和requried都有“必须的”的意思，是近义词，B指“强迫的”，C指“请求的”，D指“需求的，要求的”，最佳答案是A。

10、Electric BackpackBackpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don\'t mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home.Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass, have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions, search-and-rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS) receivers, night-vision goggles, and other battery-powered devices to get around and do their work. The backpack\'s electricity-generating feature could dramatically reduce the amount of a wearer\'s load now devoted to spare batteries, report Rome and his colleagues in the Sept. 9, Science.The backpack\'s electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer\'s back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7. 4 watts.Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack\'s oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack.The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren\'t on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street!Backpacks are convenient because .【单选题】
