Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills(風(fēng)車) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind(碾碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher cost. Today, there is a global movement to supply more and more of our electricity through the use of wind.

Sigmund Freud was one of the first scientists to make serious research of the mind. The mind is the collection of activities based in the brain that involve how we act, think, feel and reason.
He used long talks with patients and the study of dreams to search for the causes of mental and emotional problems. He also tried hypnosis(催眠術(shù)). He wanted to see whether putting patients into a sleep-like condition would help ease troubled minds. In most cases he found the effects only temporary.
Freud worked hard, although what he did might sound easy. His method involved sitting with his patients and listening to them talk. He had them talk about whatever they were thinking. All ideas, thoughts and anything that entered their mind had to be expressed. There could be no holding back because of fear or guilt.
Freud believed that all the painful memories of childhood lay buried in the unconscious self. This part of the mind he said contains wishes, desires and experiences too frightening to recognize.
He thought that if these memories could somehow be brought into the conscious mind, the patient would again feel the pain. But this time, the person would experience them as an adult. The patient would feel them, be able to examine them and, if successful, finally understand them.
Using this way, Freud reasoned, the pain and emotional pressure of the past would be greatly weakened. They would lose their hold over the person's physical health. Soon the patient would get better.
Many of Freud's theories about how the mind works also had strong sexual connections. These included what he saw as the repressed feelings of sons toward their mothers and daughters toward their fathers.
If nothing else, Freud's ideas were revolutionary. Some people rejected them. Many others came to accept them. But no one disputes his great influence on the science of mental health.
【小題1】How many methods did Sigmund Freud use to study the mind?
A.One. | B.Two. | C.Three. | D.Four. |
A.he had to work hard and have patients talk freely |
B.he had to live with people who had troubled minds |
C.he had to listen to unhappy stories of different people |
D.he had to give his patients a sense of security |
A.could be forgotten forever |
B.could have a life-long influence |
C.could become wises and desires |
D.could be understood unconsciously |
A.have physical and mental problems |
B.be greatly influenced by them |
C.have a better understanding of life |

Researchers found that walking around with a forced smile and fake (假的) happiness simply leads to people feeling unhappier. So, putting a brave face on your sadness could be harmful. The research also found that women suffered more than men when pretending to be happy.
Dr. Brent Scott, who led the study, said employers should take note because forcing workers to smile when dealing with the public can result in bad outcomes. He said, “Smiling for the sake of smiling can lead to emotional tiredness, and that’s bad for the organization.” He also said the research showed customer-service workers who had “fake smiles” throughout the day fell into a bad mood and didn’t want to work, so their productivity dropped.
The study is one of the first of its kind to examine emotional expressions over a period of time and compare the different effects on men and women. Dr. Scott’s team examined the effects of “surface acting”, or fake smiling, compared to “deep acting”, or making people smile by thinking of pleasant memories.
Dr. Scott said, “Women were harmed more by surface acting, meaning their moods worsened even more than men’s. However, they were helped more by deep acting, which means their moods improved more by thinking of pleasant memories. ”
According to Dr. Scott, women tend to suffer more when pretending to be happy because they are expected to be more emotionally expressive than men. Therefore, forcing a smile while feeling down is more likely to go against their normal behavior and cause more harmful feelings.
Although deep acting can improve moods a little in the short term, Dr. Scott says, it’s not a long-term solution to feeling unhappy. “There have been some suggestions that if you do this over a long period you start to feel unreal. You’re trying to develop positive emotions, but at the end of the day you may not feel like yourself any more.”
【小題1】According to the passage, Dr. Scott’s study ______.
A.is supported by some big employers in the USA |
B.is meaningful as there haven’t been many similar ones |
C.examined more women than men for a long time |
D.a(chǎn)imed to make the employees more productive |
A.they usually become shy in public places |
B.they are supposed to be more emotionally expressive |
C.they are often treated in a terrible way |
D.they like thinking of pleasant memories |
A.doesn’t have any effect on men |
B.cannot improve our moods in any case |
C.harms our feelings in the long run |
D.pleases people by feeling like another person |

How long do you want to live? How many years might be added to a life? Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.(壽命)
“I think we are knocking at the door of immortality(永生) , " said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that's a conservative estimate(保守的估計(jì))."
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(納米技術(shù)) make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.
However, many scientists who research into ageing are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say the failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120,you know, could you be healthy enough to have good quality of life?" said Leonard Poon, director of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."

Pollutants coming from automobile operation have begun to cause many environmental problems. It has been calculated, for example, that 70% of the carbon monoxide(一氧化碳), 45% of the nitrogen oxides(氮氧化合物), and 34% of the hydrocarbon (碳?xì)浠衔? pollution in the United States can be traced directly to automobile exhausts (廢氣). In addition, rubber, motor oil and other materials accumulate on roadways and are washed into streams, with effects nearly as serious as those of untreated waste water.
In an effort to improve the situation, the U.S. government has made regulations on the use of the constituents (成分) of automobile exhaust gas that are known to cause air pollution. These constituents fall roughly into three types: hydrocarbons that pass through the engine unburned; carbon monoxide, also a product of incomplete burning; and nitrogen oxides which are formed when nitrogen and oxygen are in contact at high temperatures. Besides their own poisonous character, hydrocarbons and nitrogen oxides react in the presence of sunlight to form harmful smog. Carbon monoxide and hydrocarbons are rather easily controlled by the use of higher burning temperatures in engines. Unfortunately, the conditions that produce minimum emission of hydrocarbons tend to raise emission of nitrogen oxides. In a way this difficulty is solved by adding recycled exhaust gas to the fuel mixture, thus avoiding the oversupply of oxygen that favors formation of nitrogen oxides.
California, which has the most strict air-pollution laws in the United States, requires further special compounding of gas to control emissions, and several states have ordered that alcohol be mixed with gas, as this will reduce emissions of the carbon monoxide by 35 per cent and the hydrocarbons by 15 per cent.
【小題1】The author uses figures in Paragraph 1 ________.
A.to reflect the rapid growth of automobile use |
B.to highlight the importance of environment protection |
C.to show the consequence of automobile exhausts |
D.to criticize the low quality of cars |
A.Nitrogen and oxygen are put together in great heat. |
B.Carbon monoxide and oxygen are mixed together. |
C.Hydrocarbons pass through the engine. |
D.Nitrogen is burned incompletely. |
A.Carbon monoxide can be controlled in the engine. |
B.Smog will form when hydrocarbons meet nitrogen oxides in the sunlight. |
C.Hydrocarbons have no poisonous character themselves. |
D.The conditions that decease emission of hydrocarbons will increase emission of nitrogen oxides. |
A.increase awareness of environment protection |
B.control air pollution |
C.increase the fuel efficiency |
D.replace gas gradually |

The olinguito(小尖吻浣熊)is new to science. Although lt has been living in the cloud forests of South Amcrica for some time.
Scientists say the olinguito is the first new carnivore(食肉動物)discovered In the Americas in more than 30 years. It is a hairy orange-brown creature with a sweet face and big eyes The animal has small. rounded ears and lives in the trees An adult weighs one kilogram and measures about 75 centimeters. with half of those centimeters taken up by its ringed tail Most of the time. it likes to eat fruit, although it also eats meat. Active at night, the animal has lived in Colombia and Ecuador for a long time. But the olinguito did not exist in science books before now.
Kristofer Helgen, director at the National Museum in Washington, led the research team that confirmed the existence of the olinguito. It had been mistaken more than a century ago for a look-alike animal -- a similar but larger olingo(尖吻浣熊). Mr. Helgen had been studying olingos in a museum for ten years. At that time. he observed a difference in the size and shape of the heads and teeth. That led him on an effort to prove he was looking at an animal never before described by science. He got lucky when he communicated with a zoologist in Ecuador. The animal expert there made a short video that shows an olinguito in the trees. The video confirms that the oiinguito is different from the olingo Mr. Helgen says tens of thousands of olinguitos live in the wild and are not in danger of disappearing forever. Human beings, however, are moving closer to the olinguito habitat in the Andean cloud forests. The research team estimates that 42 percent of historic olinguiio habitat has been removed
【小題1】Comparcd with most carnivores. the olinguito may seem more _____.
A.terrble | B.fierce | C.clever | D.lovely |
A.it was mistaken for another species |
B.it was active in the eveing |
C.it was too small to be seen clearly |
D.it covered itself by its long tail |
A.Having been studying olingos for ten years. |
B.The short video the animal expert made. |
C.His communication with an expert in Ecuador. |

Recently a Beijing father sent in a question at an Internet forum(論壇) asking what “PK” meant. “My family has been watching the ‘Super Girl’ singing competition TV program. My little daughter asked me what ‘PK’ meant, but I had no idea,” explained the puzzled father.
To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, “PK” is short for “Player Kill”, in which two players fight until one ends the life of the other.
In the case of the “Super Girl” singing competition, “PK” was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.
Like this father, Chinese teachers at high schools have also been finding their students’ compositions using Internet jargons(行話) which are difficult to understand. A high school teacher from Tianjin asked her students to write compositions with simple language, but they came up with a lot of Internet jargons that she didn’t understand.
“My ‘GG’ came back this summer from college. He told me I’ve grown up to be a ‘PLMM’. I loved to ‘FB’ with him together; he always took me to the ‘KPM’,” went one composition.
“GG” means Ge Ge(Chinese pinyin for brother). “PLMM” refers to Piao Liang Mei Mei(beautiful girl). “FB” means Fu Bai(corruption). “KPM” is short for KFC, Pizza Hut and McDonald’s.
Some specialists welcome Internet jargons as a new development in language.
If you do not even know what a Kong Long(dinosaur, referring to an ugly looking female) or a Qing Wa(frog, referring to an ugly looking male) is, you will possibly be regarded as a Cai Niao!
【小題1】By writing the article, the writer tries to .
A.explain some Internet language |
B.suggest common Internet language |
C.laugh at the Beijing father |
D.draw our attention to Internet language |
A.Fathers can’t possibly know it. |
B.The daughter should understand it. |
C.Online game players may know it. |
D.“Super Girl” shouldn’t have used it. |
A.a(chǎn)re used not only online |
B.can be understood very well |
C.a(chǎn)re welcomed by all the people |

If your idea of a good time is to sleep in a hut, carry your own rubbish, and eat insects and wild animals, then ecotourism may be just for you. But is it also for people who want to fly over a rainforest sky before checking into a comfortable and expensive hotel in the middle of a national park? Whatever ecotourism is, it is hot--perhaps too hot for its own good.
The World Tourism Organization claims that the industry looked after 592 million travelers last year who spent $423 billion, and of all the types of tourism, ecotourism seems to be the fastest growing. By the broadest measure -- a trip with some sort of nature or wilderness element -- ecotourism already accounts for perhaps a third of these travelers. On a stricter definition favored by the Ecotourism Society, it is “responsible travel that preserves natural environments and keeps up the well-being of local people,” which accounts for no more than 5% of tourism.
Ideally, ecotourism helps both people and nature. Before the disastrous civil war, Rwanda’s Mountain Gorilla Project was one such model. Visits to the gorillas were limited, local guides ensured good behavior or on the part of the humans, and the high admission charge - $170 a day -- paid for salaries and presentation of the gorillas’ living areas. As this made the gorillas worth more alive than dead, poaching (偷獵) decreased. As another example, preservation Cooperation, Africa’s largest ecotour operator, uses only local labor, buys products 5om local farmers, and supports building projects: such as clinics and schools. This contribution to social advance is also good business sense. Projects from which local people benefit directly are less likely to be affected by poaching and theft.
Ecotourism’s biggest problem is labeling. Going on an eco-tour is no guarantee of good ecology. So far, only Australia has an official system to grade tour operators and tourist attractions on the basis of their “greenness”. Another issue is how eco-tourists damage the environment. Dolphin-feeding, for instance, is innocent and enjoyable, but after too many free meals, the dolphins forget how to catch their own dinners.
Keeping prices high is one way to limit enthusiasm. But measuring the effect of ecotourism on human environments is trickier. It is common, for villagers to see ecotourism as a source of new income. Hence, the very tourists who venture in search of traditional cultures end up breaking them up. As ecotourism becomes more popular, it will finally threaten the very things that are good for business.
【小題1】According to the passage, ecotourism may _________.
A.harm its own purpose by becoming too popular |
B.save the environment by becoming more popular |
C.harm its own purpose by becoming less popular |
D.save the environment by becoming less popular |
A.has no single, clear definition that would satisfy everybody |
B.has expanded less rapidly than other types of tourism |
C.claims that no comfortable hotels should be used by tourists |
D.most often has a negative effect on local culture |
A.tourists were free to visit the gorillas whenever they wanted to |
B.local people’s attitudes toward animals were not affected |
C.the gorillas were protected from both tourists and local people |
D.the gorillas’ living area was modernized because of the high admission |
A.Rwanda’s Mountain Gorilla Project | B.Preservation Corporation |
C.Australia’s grading system | D.Dolphin-feeding |
