1、A Strong Greenhouse Gas
1 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.
Paragraph l ____
【单选题】

A.Life of Macroscopic Bacteria in Livestock's Rumen

B.Ways to Reduce Methane's Heat-trapping Power

C.Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere

D.Why Livestock Releases Methane

E.Methane as a Strong Greenhouse Gas

F.Livestock as a Prime Factor of the Greenhouse Effect

正确答案:E

答案解析:本段的第3句点出了“methane's heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide. ”

2、The State of Marriage Today
Is 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。

3、Status of Teachers in America
At present, in many American cities especially, many teachers in the public schools say they are underpaid. They point to jobs such as secretary or truck driver, which often pay more to start than that of the teacher. In many other fields, such as law, medicine, computer science, a beginning worker may make more than a teacher who has taught for several year.
Teaching has never been a profession that attracted people interested in high salaries. It is by history a profession that has provided rewards in addition to money, the satisfaction of sharing knowledge, of influencing others, of guiding young people. But in the past several years, there are more difficulties in teaching, for many, than there are rewards.
Unruly students, who would have chosen teaching as their life career in the past, are going into other fields.
Another reason for this change in teacher candidates is the changing status of women in the United States. Until the late 1960s and 1970s, one of the most popular choices for women was teaching. But as other professions, such as law and medicine opened up to women, women stopped pouring into teacher training programs. Thus, a major pool of excellent candidates for the teaching profession dwindled(减少).
Bit by bit government officials and others realized that the status of the teacher had suffered. They talked about change. But change in a vast society like the United States is not easy. People's attitudes have formed over many years, and sometimes change takes many years.
Which of the following is not a reason that influences women in their decision to become teachers?【单选题】

A.How much income the job can pay.

B.The changing status of women.

C.Less housework for women to do.

D.More professions opened up to women.

正确答案:C

答案解析:A选项可以在第2段中找到;B和D选项可以在第4段中找到,只有C选项没有提到。按照常理,选择当老师不可能是由于女人家务事少,因此选C。

4、Electric Backpack
Backpacks 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!
What is the most important feature of the backpack invented by Lawrence C. Rome and his colleagues?【单选题】

A.It produces electricity for electronic devices while the wearer walks.

B.It can be used as cell phones, GPS in the military actions or field studies.

C.It is small and convenient.

D.It is light and easy to carry.

正确答案:A

答案解析:第2段的第1句说,Lawrence C. Rome及其同事们发明的这种背包,当背着背包走路时,会有电能产生。该段最后一句告诉我们,背包的这种性能可减少背包的重量,因为不必携带备用电池。

5、The Race into Space
American millionaire Dennis Tito will always be famous. He was the first tourist in space. "I spent sixty years on Earth and eight days in space and from my viewpoint, it was two separate lives," Tito explained. He loved his time in space. "Being in space and looking back at earth is one of the most rewarding experiences a human being can have."
This kind of experience isn't cheap. It cost $ 20 million. However, Tito achieved his dream, so he was happy. "For me it was a life dream. It was a dream that began when didn't have any money," he told reporters.
On 30 April 2002, Mark Shuttleworth became the world's second space tourist. Shuttleworth is a South African businessman. At the age of twenty - eight, he also paid $ 20 million for the eight - day trip.
Both Tito and Shuttleworth bought their tickets from a company called Space Adventures. The company has around 100 people already on their waiting list for flights into space. The spaceship to take them doesn't exist yet.
Many of the customers are people who like adventure. They are the kind of people who also want to climb Mount Qomolangma. Other customers are people who love space. However, these people are worried. Because it’s so expensive, only very rich people can go into space. They want space travel to be available to more people.
That day may soon be here. Inter Orbital Systems (IOS) plans to send up to four tourists a week into space. The tours will depart from an island in Tonga. The company promises a package that includes forty-five days of astronaut training in Russia and California, seven days in space, and a vacation in Tonga, for $2 million.
However, space flight is still very dangerous. Bill Readdy is NASA's deputy assistant administrator for space flight. He says that the chances of dying are about 1 in 500. Because of this, it may take time before space tourism really takes off. You might be able to go up, but will you come down?
Mark Shuttleworth is an engineer from the United States.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题难度不大,比较容易找到答案依据。带着题干提示词Mark Shuttleworth迅速回到文章定位。文中第三段谈到,Mark Shuttleworth是世界上第二个太空旅行者,他是一个南非商人……,所以,此人不是美国人,而是南非人,所以本题错误,答案是B。
