【题目】Global warming may or may not be the great environmental crisis of the 21st century, but—regardless of whether it is or isn’t — we won’t do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.

Al Gore calls global warming an “inconvenient truth,” as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and—without major technological breakthroughs—we can’t do much about it.

From 2003 to 2050, the world’s population is estimated to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. But that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn（注定）the world’s poor people to their present poverty and freeze everyone else’s living standards. With modest economic growth, energy use and greenhouse emissions more than double by 2050.

No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something.” Consider the Kyoto Protocol (京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn’t adopt tough enough policies to hit their 2008-2012 targets.

The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking our dependence on fossil fuels or dealing with it.

The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.

【1】What is said about global warming in the first paragraph?

A. It may not prove an environmental crisis at all.

B. It is an issue requiring worldwide commitments.

C. Serious steps have been taken to avoid or stop it.

D. Very little will be done to bring it under control.

【2】According to the author’s understanding, what is A1 Gore’s view on global warming?

A. It is a reality both people and politicians are unaware of.

B. It is a phenomenon that causes us many inconveniences.

C. It is a problem that can be solved once it is recognized.

D. It is an area we actually have little knowledge about.

【3】Greenhouse emissions will more than double by 2050 because of ________.

A. economic growth

B. wasteful use of energy

C. the widening gap between the rich and poor

D. the rapid advances of science and technology

【4】The author believes that, since the signing of the Kyoto Protocol, ________.

A. politicians have started to do something to better the situation

B. few nations have adopted real tough measures to limit energy use

C. reductions in energy consumption have greatly cut back global warming

D. international cooperation has contributed to solving environmental problems

【5】What is the message the author intends to convey?

A. Global warming is more of a moral issue than a practical one.

B. The ultimate solution to global warming lies in new technology.

C. The debate over global warming will lead to technological breakthroughs.

D. People have to give up certain material comforts to stop global warming.

【答案】

【1】D

【2】C

【3】A

【4】B

【5】B

【解析】

试题分析: 本文主要将关于全球变暖的问题。关于全球变暖在当前如何解决，作者指出了两点，一是它已经演变成了道德问题，二是只能通过技术突破来解决。

【1】D 推理判断题。根据第一段Global warming may or may not be the great environmental crisis of the 21st century, but—regardless of whether it is or isn’t — we won’t do much about it可知全球变暖可能成为危机也可能不会变成危机，但不管会否变为，我们都不会采取什么措施。这是一个转折句，通常情况下，转折之后的句子具有更重要的意义。可知焦点是我们不会采取措施来应对它。故选D.

【2】C 推理判断题。第二段提到Gore的观点只用了一个词组，即inconvenient truth，字面意思是“会给人们带来不方便的真相”，从这个词组无法判断出其具体含义。此后作者使用了一个as if从句As if merely recognizing it could put us on a path to a solution对这个词组进行描述，“好像仅仅承认它就会使我们走上解决它的道路”，意思也就是承认它就能解决它。这应该是作者对Gore观点的全部理解，此后的几句以But引出转折，是作者开始表达自己的观点，与Gore无关。故选C.

【3】A 细节题。根据第三段With modest growth, energy use and greenhouse emissions more than double by 2050可知温室排放翻倍的原因是modest growth，即适度增长。这里的增长当然是指经济增长，economic作了承前省略处理。故选A.

【4】B 推理判断题。根据第四段No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming可知没有政府抵制经济增长和限制个人的自由(限制用电，驾车和旅行)。再根据后文But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories didn’t adopt tough enough policies to hit their 2008-2012 targets可知它没有减少二氧化碳排放量，许多签署国没有采取足够严格的措施来实现2008-2012的目标。这里所说的目标即是限制能源使用。故选B.

【5】B 态度观点题。根据文章最后一段the trouble with the global warming debate is that it has become a moral problem when it’s really engineering one。engineering one是指工程问题，也就是实际问题。可知作者更倾向于认为全球变暖是一个实际问题，只是现实情况使它变成了一个道德问题，体现出作者的一种无奈感。故选B.

【题目】Here’s one number to keep in mind during your next cell phone conversation: 50. A new experiment shows that spending 50 minutes with an active phone pressed up to the ear increases activity in the brain. This brain activity probably doesn't make you smarter. When cell phones are on, they emit (发出) energy in the form of radiation that could be harmful, especially after years of cell phone usage. Scientists don't know yet whether cell phones are bad for the brain. Studies like this one are attempting to find it out.

The 47 participants in the experiment may have looked a little strange. Each one had two Samsung cell phones attached to his or her head — one on each ear. The phone on the left ear was off. The phone on the right ear played a message for 50 minutes, but the participants couldn't hear it because the sound was off.

With this set-up, the scientists could be sure they were studying brain activity from the phone itself, and not brain activity due to listening and talking during a conversation. After 50 minutes with two phones strapped to their heads, the participants were given PET scans.

The PET scan showed that the left side (the side with the phone turned off) of each participant's brain hadn't changed during the experiment. The right side of the brain, however, had used more glucose, which is a type of sugar that provides fuel to brain cells. These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that the brain cells there were active ― even without the person hearing anything. That activity, the scientists say, was probably caused by radiation from the phone.

Henry Lai, who works at the University of Washington in Seattle, is uncomfortable with the data related to cell phones. Holding a cell phone to your ear during a conversation is “not really safe,” Lai told Science News. Lai is a bioengineer at the University of Washington in Seattle. He wrote an article about the new study for a journal, but he did not work on the study. Bioengineers bring together ideas from engineering and biology.

For those who don't want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely. You can have short and sweet conversations, use a speakerphone or keep the phone away from your head.

【1】Which of the following statement is true?

A. Scientists are sure that cell phones are bad for the brain.

B. In the experiment, the left side of the brain used more glucose.

C. Radiation from the phone probably causes the change in the brain.

D. Henry Lai wrote a lot of articles about this new study.

【2】Why weren’t the participants allowed to have a conversation on the phone during the experiment?

A. Because the scientists want to be sure of the accuracy of the experiment.

B. Because they really looked strange and no one wanted to talk to others.

C. Because they were given PET scans and they lost the ability to talk.

D. Because that would be too noisy and bad for the experiment.

【3】What is glucose?

A. A type of sugar that provides vitamin to brain cells.

B. Something that the right side of the brain used.

C. A type of sugar that gives energy to brain cells.

D. Something that makes a human excited.

【4】According to the last two paragraphs, which is the safest way to use a cell phone?

B. Using a cell phone more than three hours a day.

C. Taking the most powerful cell phone.

D. Keeping the cell phone at a distance.

【题目】Pulling heavy suitcases all day in the summer is hard work, especially when you are a thin 14-year-old boy. That was me in 1940-the youngest and smallest baggage boy at New York City's Pennsylvania Railway Station.

After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I'd like to join them, thinking, "Everyone else is doing it."

When I got home that night, I told my dad what I wanted to do. "You give an honest day's work," he said, looking at me straight in his eye. "They are paying you. If they want to do that, you let them do that."

I followed my dad's advice for the rest of that summer and have lived by his words ever since.

Of all the jobs I've had, it was my experience at Pennsylvania Railway Station that has stuck with me. Now I teach my players to have respect for other people and their possession. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he'd be gone.

Whether you're on a sports team, in an office or a member of a family. if you can't trust one another, there is going to be trouble.

【1】What can be inferred about the baggage boys?

A. They could earn much, but they had to work hard.

B. Many of them earned money in a dishonest way.

C. They were all from poor families.

D. They were thin, young boys.

【2】What does the father's advice imply?

A. It is wrong to give more to the passengers.

B. Don't believe them if they are paying you more.

C. Don't follow others to overcharge the passengers.

D. It is difficult to work hard and live as an honest boy.

【3】The writer can't put up with stealing because he thinks that _______.

A. it is a total shared experience

B. it is considered as the most dangerous

C. it does great harm to human relationship

D. it may led to the loss of his sports team.

【4】It can be concluded from the text that _______.

A. his father's advice helped him to decide which job to take up

B. working in the sports team was his most important experience

C. he learned much from his shared experience with his team members

D. his experience as a baggage boy had a great influence on his late life

【题目】He is very popular among his students as he always tries to make them __________ in his lectures.

A. interested

B. interesting

C. interest

D. to interest

【题目】Educating Girls Is a Real Lifesaver

Clare Short knows it. Every developing economist knows it. The World Bank knows it. The education of girls is the surest way to reduce poverty.

The reason is simple. All the evidence shows that taking girls out of the fields and homes, and putting them behind desks, raises economic productivity, lowers infant and maternal(产妇) death rates, reduces birth rates, and improves environmental management.

Why, then, are 90 million primary school-age girls around the world not in school? For the same reason that when Charles Dickens was writing David Copperfield 150 years ago girls were absent from the British education system: Men in power mostly prefer it that way, or are not interested enough in changing the situation to commit energy and money to doing so.

The countries with the poorest record for having women in positions of power or influence have the worst figures for girls’ education. High-profile intervention(介入) by organizations such as the World Bank has begun successfully with several countries, and more of the same will probably be needed to bring change in conservative, male-run states.

Even if there were no development payoff from gender equality in schools, the education of girls would still be a cause worth fighting for. Education is a human right, and the denial of it to girls is a scar on the community in the twenty-first century.

To be born a girl in a rural area in Nepal, Pakistan, Indonesia, Morocco, Togo, or Sudan — half a dozen of the most shameful performers — means being condemned to a life without school, education, or clean water, marriage and babies coming too early, too many births, children who die of preventable diseases, backbreaking work in the fields, subordination(从属) to husband and his family, and an early death.

Every year, almost 12 million children under the age of five needlessly die of infectious diseases associated with poverty. But each additional year spent by their mothers in primary school lowers the risk of premature child deaths by about 8 percent. In Pakistan, an extra year of school for 1,000 girls could prevent sixty infant deaths.

With women and girls being the main farmers in Africa and southern Asia, their education offers a chance to develop more efficient farming practices, improve output, and raise awareness of the ecological needs of the land with tree planting and farming. Therefore, the world community cannot afford to ignore this avenue of change.

【1】Which is Not the reason why educating girls reduces poverty?

A. It improves environmental management.

B. It raises economic productivity.

C. It creates more children.

D. It lowers maternal death rates.

【2】What does the underlined word “it” in Paragraph 3 refer to?

A. The poor economy at that time.

B. Girls’ absence from school.

C. Energy and money.

D. The education of girls.

【3】Which of the following is TRUE according to the passage?

A. The countries where women have great influence and are in power always do worse in girls’ education.

B. Some organizations such as the World Bank haven’t taken the lead in girls’ education.

C. Some girls in Sudan and Indonesia are bound to live a life without education when they are born.

D. Each extra year of school for girls has nothing to do with the birthrate and maternal deaths.

【4】How many more infants will survive when 100 girls stay in school for another year?

A. 5 B. 6 C. 8 D. 12

【5】What does the author think of girls’ education?

A. essential B. terrible

C. indifferent D. helpless
