While other countries debate whether to fix wind turbines(渦輪機(jī)) offshore or in distant areas, Denmark is building them right in its capital. Three windmills(風(fēng)車) were recently introduced in a Copenhagen neighbourhood, and the city plans to add another 97.

“We’ve made a very ambitious commitment to make Copenhagen CO2-neutral by 2025,” Frank Jensen, the mayor, says. “But going green isn’t only a good thing. It’s a must.” The city’s carbon-neutral plan, passed two years ago, will make Copenhagen the world’s first zero-carbon capital.

With wind power making up 33% of Denmark’s energy supply, the country already features plenty of wind turbines. Indeed, among the first sights greeting airborne visitors during the landing at Copenhagen’s Kastrup airport is a chain of sea-based wind towers. By 2020, the windswept country plans to get 50% of its energy from wind power.

Now turbines are moving into the city and these ones will cost less than half the price of those sea-based. Having the energy production closer makes it cheaper, and land-based turbines are the cheapest possible source of energy available today. Fixing them also makes the locals more aware of their energy consumption.

Though considerably less attractive than it was in ancient times, the windmill is enjoying popularity in the 21st century. “Windmills are a symbol of the new and clean Copenhagen,” says resident Susanne Sayers. Meanwhile, fellow Copenhagen citizen Maria Andersen worries about the noise, explaining that she wouldn’t want a wind turbine in her neighbourhood. While Copenhagen citizens approve of the windmills, they’re less willing to live close to one. The answer, the city has decided, is to sell turbine shares.

Each share represents 1,000 kW hours/year, with the profit tax-free. With a typical Copenhagen household consuming 3,500 kW hours/year, a family buying four shares effectively owns its own renewable energy supply. To date, 500 residents have bought 2,500 shares. Involving the local population was a smart move. “There are a lot of things you can do close to people if it’s not too big and if there’s a model where locals feel involved and get to share in the profit. Knowing that you, or your neighbours, own a technology creates a very different atmosphere than if a multinational owned it,” says Vad Mathiesen.

Going green? Yes. Accepted by the population? Yes. Going with centuries-old city architecture? Hardly.

Certainly, the three turbines don’t exactly blight the 18th-century city centre, as they are in a neighbourhood 3 km away. According to the mayor’s office, none of the remaining 97 turbines will rise in architecturally sensitive areas. But Sascha Haselmayer, CEO of city creation group Citymart, warns, “With Denmark being a world-leading producer of windmills, there is a risk that the answer to every energy question is windmills.”

“We’ve destroyed mountains and lakes in order to support our lifestyle,” notes Irena Bauman, an architect and professor at Sheffield University. “Wind turbines are a sign that we’re learning to live with nature. I hope we’ll have them all over the world,” she says. “They may be unpleasant to some, but better-looking ones will come. It’s just that we don’t have time to wait for them!”

1.Denmark has decided to build windmills in its capital mainly to ______.

A. make windmills its cultural symbol

B. advocate an environmentally-friendly lifestyle

C. take advantage of its limited wind power

D. greet tourists coming to Copenhagen by plane

2.How has the city of Copenhagen persuaded its people to accept the windmills around their homes?

A. By promising them that all their income is free of tax.

B. By designing less noisy windmills to ease their worries.

C. By convincing them that land-based turbines are much cheaper.

D. By offering them the chance to get the profit the windmills bring.

3.The underlined word “blight” (Paragraph 8) is closest in meaning to ______.

A. spoil B. improve C. pollute D. occupy

4.Sascha Haselmayer’s attitude to building windmills can best be described as ______.

A. disapproving B. unconcerned C. cautious D. enthusiastic

5.Which of the following words would Irena Bauman most probably agree with?

A. “It benefits us more to fit wind turbines in cities than in mountain areas or by lakes.”

B. “We should sell more wind turbines to other countries to make us one of the richest.”

C. “We should devote more time to developing the wind turbines that go with the city.”

D. “It’s not what wind turbines look like but how we live that really matters at present.”

China’s Jade Rabbit moon rover (月球車)has “ woken up” since it entered the lunar night two weeks ago. The moon rover, known as Yutu in Mandarin Chinese, and the Chang’e-3 lander were restarted by the Beijing Aerospace Control Center (BACC), China’s Xinhua news agency said.

It had been set to sleep for two weeks to ride out extreme climatic conditions and will finally undertake its scientific mission. The Jade Rabbit was “ put to sleep” on 26 December at the onset of the first lunar night of the mission. One night on the moon lasts for around two weeks on Earth and during this time, temperatures fall to -180℃ ---conditions too cold for the equipment to function in. There is also no sunlight to power the Jade Rabbit’s solar panels.

Zhou Jianliang, chief engineer with the BACC, explained: “ During the lunar night, the lander and the rover were in a power-off condition and the communication with Earth was cut off.

“ When the night ends, they will be started up with the power provided by sunlight and resume operation and communication according to preset programmes. He added that the Jade Rabbit surviving the lunar night showed Chinese technology had proved successful.

The Jade Rabbit and the lander compose Chang’e-3 landed on the moon on 14 December. With the landing, China became one of only three nations to soft-land on the moon, and the first to do so in more than three decades.

Scientists said the mission was designed to test new technologies and build the country’s expertise of space exploration. The Jade Rabbit will gather scientific data and capture images from the Moon. China was planning further missions planned to collect lunar soil samples and it is thought officials are looking to conduct manned lunar landings if they prove successful.

1.Jade Rabbit fell into sleep because ________.

A. there was something wrong in the machine

B. the Chang’e-3 lander struck it by accident

C. it was designed to avoid the bad weather

D. it had completed the scientific mission

2.According to Zhou Jianliang we can know that ________.

A. on the moon the rover can’t communicate with the lander

B. sunlight is the necessary power for the rover and the lander

C. Chinese technology has been regarded the most successful

D. the lunar night can destroy the equipment on the moon

3.It can inferred from the passage that ________.

A. China had made great achievements in 10 years

B. no country can be equal to China in exploring space

C. scientists can get more proof to research the moon

D. the soil from the moon has been taken to China

4.What does the author intend to tell in the passage?

A. Jade Rabbit wakes up to begin moon mission.

B. Jade Rabbit was put to sleep on the moon.

Many of the world’s countries have reached or are approaching zero population growth (ZPG) .Nearly all such lands are economically well developed.They include much of Europe(including Russia),the United States,Canada,Japan.a(chǎn)nd Australia.As the rate of natural increase(RNI)declines,two things happen.First,the population begins to decline if the loss is not balanced by immigration.Second,a country’s population ages because there are fewer births.

Is achieving ZPG good or bad? What happens when a country’s population begins to drop? Many people,after all,believe that population decline is a good thing.But is it good for everyone? Does everyone agree?

An aging population can create many problems.Senior citizens require more health care and medical attention.Rather than paying into retirement programs,they begin to draw from their pensions.In the US,the Social Security program,according to many experts,will be used up by 2018.It will pay out more money than it takes in.Additionally, a great number of jobs go begging in search of people willing or entry。level positions that pay low wages.With an able to do them.Many of these jobs are aging population,who will fill them? At the other extreme,some positions require a large number of training and highly specialized skills.Who will fill these positions as retirees leave the workforce?

The answer to the problem of declining and aging population is simple:increased migration.Today many people,particularly those from less developed countries,are migrating in search of employment.Many are willing to take jobs that cannot(or will not) be filled by the domestic population.Others are well educated and highly skilled.Both groups contribute to a country’s economy progress in many ways.Further, they add to the richness of a country’s culture.Of greatest importance,perhaps,is the fact that they have become absolutely necessary to the economy of many lands.As you can see,for many countries and for most immigrants,migration is a win—win situation.

1.In the writer’s view,which of the following statements is TRUE?

A.Not everyone agrees that achieving ZPG is absolutely good.

B.Achieving ZPG is every country’s aim in spite of its side effects.

C.Achieving ZPG is bad for senior citizens.

D.Achieving ZPG is good for employment.

2. According to the passage,the best way to solve the problem of declining and aging population is .

A.to improve the health care system B.to increase RNI

C.to increase employment D.to increase migration

3.The underlined words “the domestic population’’ can be replaced by .

A.people within the country B.people from developing countries

C.people without a college education D.people living abroad

4.The main idea of the last paragraph is

A.the advantages of increased migration

B.the problem of declining and aging population

C.how to increase migration

D.some ways to enrich a country’s culture

Mary is digging in the ground for a photo, when along comes John. Seeing that there is no one in sight, John starts to scream. John’s angry mother rushes over and drives Mary away. Once his mum has gone, John helps himself to Mary’s potato.

We’ve all experienced similar annoying tricks when we were young—the brother who stole your ball and then got you into trouble by telling your parents you had hit him. But Mary and John are not humans. They’re African baboons(狒狒). __1._

John’s scream and his mother’s attack on Mary could have been a matter of chance, but John was later seen playing the same tricks on others. ___2.___

Studying behavior like this is complicated but scientists discovered apes(猿) clearly showed that they intended to cheat and knew when they themselves had been cheated. ___3.___ An ape was annoying him, so he tricked her into going away by pretending he had seen something interesting. When she found nothing, she “walked back, hit me over the head with her hand and ignored me for the rest of the day.”

Another way to decide whether an animal’s behavior is deliberate is to look for actions that are not normal for that animal. A zoo worker describes how an ape dealt with an enemy. “He slowly stole up behind the other ape, walking on tiptoe. When he got close to his enemy, he pushed him violently in the back, then ran indoors.” Wild apes do not normally walk on tiptoe. ___4.__ But looking at the many cases of deliberate trickery in apes, it is impossible to explain them all as simple copying.

It seems that trickery does play an important part in ape societies. ____5.__ Studying the intelligence of our closest relative could be the way to understand the development of human intelligence.

A. In most cases the animal probably doesn’t know it is cheating.

B. An amusing example of this comes from a psychologist working in Tanzania.

C. And playing tricks is as much a part of monkey behavior as it is of human behavior.

D. So the psychologists asked his colleagues if they had noticed this kind of trickery.

E. The ability of animals to cheat may be a better measure of their intelligence than their use of tools

F. This use of a third individual to achieve a goal is only one of the many tricks commonly used by baboons.

G. Of course it’s possible that it could have learnt from humans that such behavior works, without understanding why.

Ever since Canadian psychiatrist Michael R. Phillips, who works in China, released his report saying China’s suicide rate from 1995 to 1999 reached 0.023 percent, the country has been ranked among those with the highest suicide rates in the world. But Jing Jun, a professor of sociology in Tsinghua University, challenges that view and presents the true picture through his nationwide research.

Jing and his students took one year to set up the first national database on suicide rate to grasp the overall trend of suicides in China. They collected data from the Health Statistics Annuals of the World Health Organization (sample size 10 million), and the country’s Health Statistics Annuals (which cover 100 million people). The database covers 23 years, from 1987 to 2009. Jing calculates the suicide rate in China based on these data. Though the suicide rate was comparatively high in the early years, his study shows it has dropped in recent years, as opposed to the ascending trend in the rest of the world.

According to Jing’s calculation, China’s suicide rate had dropped to about 0.01 percent in 2004. In 2009, the figure dropped further to 0.007 percent, which is rather low compared with the global rate of 0.016 percent. Even if the “missing” suicides were added, China’s suicide rate in 2009 would still be below 0.008 percent.

Jing has found that one of the main reasons why the suicide rate has dropped was the steady and big decline in the number of suicides committed by rural women. In the early years, researchers generally agreed that the suicide rate among Chinese women was higher than among men, which is pretty rare in the rest the world. But the suicide rate among Chinese women, especially in rural areas, has declined remarkably in recent years. In fact, it is almost equal to that of Chinese men.

As a sociologist, Jing regards suicide as a social issue, and believes improvement of social policies will reduce the suicide rate even further. More people’s lives can be saved if the authorities adjust to social environment for the better, he concludes.

1.From Jing’s search, we can see ________.

A. China has been ranked among those with the highest suicide rates in the world

B. in the rest of the world suicide rate has been rising quickly in the last few years

C. different from Michael R. Philip’s idea, the trend of suicides in China is declining

D. the suicide rate among Chinese women is lower than that of men

2.The data in Para. 2 is mainly to prove that ________.

A. the result from Jing’s research is believable

B. Jing’s research is more complicated than Michael R. Phillip’s

C. Jing has made great efforts to make the research

D. China’s suicide rate was comparatively low all the time

3.Why has the suicide rate in China dropped steadily according to Jing Jun?

A. Because the life level of Chinese people has improved a lot.

B. Because China’s government has adopted measures to reduce the suicide rate.

C. Because the number of Chinese women who commit suicide has declined.

D. Because the world environment affects the suicide rate in China.

4.In Jing’s opinion, what should be done to reduce the suicide?

A. Pay more attention to rural women.

B. Continue to improve social environment.

C. Set up more mental health centers.

D. Make policies to prevent suicides.

5.We can infer that the text is _______.

A. a news report

B. a research report

C. a description of suicides

D. an introduction to a professor
