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 (偷猎) 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.
【小题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 |

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(风车) 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.
【小题1】From the text we know that windmills________.
| A．were invented by European armies |
| B．have a history of more than 2,800 years |
| C．used to supply power to radio in remote areas |
| D．have rarely been used since electricity was discovered |
| A．Sailing a boat. |
| B．Producing electricity. |
| C．Grinding wheat into flour. |
| D．Pumping water from underground. |
| A．wind power is cleaner |
| B．it is one of the oldest power sources. |
| C．it was cheaper to create energy from wind |
| D．the supply of coal and gas failed to meet needs |
| A．The advantages of wind power. |
| B．The design of wind power plants. |
| C．The worldwide movement to save energy. |
| D．The global trend towards producing power from wind. |

A funny thing happened on the way to the communication revolution: we stopped talking to one another.
I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and suddenly, I became invisible, absent from the conversation.
The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communication technology is a tragedy to the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice-mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine.
As almost every contact we can imagine between human beings gets automated, the emotional distance index goes up. You can’t even call a person to get the phone number of another person any more. Directory assistance is almost always fully automated.
I am not against modern technology. I own a cell phone, an ATM card, a voice-mail system, and an email account. Giving them up isn’t wise. They’re a great help to us. It's some of their possible consequences that make me feel uneasy.
More and more, I find myself hiding behind email to do a job meant for conversations or being relieved with voice-mail picking up because I don't really have time to talk. The industry devoted to helping me keep in touch is making me lonelier.
【小题1】Which of the following would be the best title of the passage?
| A．The Advance of Modern Technology |
| B．The Consequences of Communication Technology |
| C．The Story of Communication Revolution |
| D．The Automation of Modern Communication |
| A．The author has decided not to use his phone when he is with his friend. |
| B．Modern technology makes it hard for people to have a face-to-face talk. |
| C．The limited use of communication device brings much inconvenience to the author. |
| D．The industry intended to keep people in touch is taking them away from each other. |
| A．satisfying | B．encouraging |
| C．disappointing | D．embarrassing |
| A．modern technology is bridging the people |
| B．modern technology is separating the people |
| C．modern technology is developing too fast |
| D．modern technology is interrupting people |

You can’t always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn’t think that forgetting to check the weather forecast before heading out should result in you getting wet. That’s why he created Lampbrella, a lamp post with its own rain sensing umbrella.
The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp,” he said.
The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors(传感器)then ensure that the umbrella offers pedestrians (行人) shelter whenever it starts raining.
In addition to the rain sensor, there’s also a 360° motion sensor on the fiberglass street lamp which detects whether anyone is using the Lampbrella. After three minutes of not being used the canopy is closed.
According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each Lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.
While there are no plans to take Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists this creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.
【小题1】For what purpose did Belyaev create the Lampbrella?
| A．To predict a heavy rain. |
| B．To check the weather forecast. |
| C．To protect people from the rain. |
| D．To remind people to take an umbrella. |
| A．His creation was inspired by an experience. |
| B．It rains a lot in the city of Saint Petersburg. |
| C．Street lamps are protected by canopies. |
| D．He enjoyed taking walks in the rain. |
| A．motor→canopy→sensors | B．sensors→motor→canopy |
| C．motor→sensors→canopy | D．canopy→motor→sensors |
| A．The designer will open a company to promote his product. |
| B．The Lampbrella could be put into immediate production. |
| C．The designer is confident that his creation is practical. |
| D．The Lampbrella would be put on show in Moscow. |

Plastic is everywhere because plastic is an extremely useful material. It is cheap, strong and lightweight. What’s more, it can take on nearly any form or shape, from soft and stretchy (有弹性的) to hard and glasslike.
Plastic, however, is far from perfect. It may even be bad for us. Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder (注意缺陷障碍).
Two types of chemicals in particular have raised special concern lately. They are called phthalates (邻苯二甲酸盐) and Bisphenol-A (二酚基丙烷), BPA for short. Not all plastic products contain them. But the ones that do are surrounded by controversy (争议). That’s because experts disagree on how dangerous these chemicals are.
Plastic is a single word, but plastic isn’t just one thing. What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture. Plasticizers (塑化剂) are added to plastic during the manufacturing process.
Phthalates and BPA are two types of plasticizers that work in different ways. Phthalates add softness to things like shampoo bottles, raincoats and rubber. They are also used in perfumes and makeup. BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles. BPA also appears in food and soda cans, DVDs and other unexpected places.
How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep (渗透) out of the plastic. Even though we can’t see them, we eat them, drink them and breathe them in.
Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic. Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three. California and Washington have done the same. And a number of other states are considering similar rules. As for BPA, Canada became the first country to ban the chemical from baby bottles. A dozen states are considering it.
【小题1】What can we know about the plastic from the first paragraph?
| A．Its characters and effects. | B．Its wide use and bad points. |
| C．Its importance and chemicals. | D．Its popularity and advantages. |
| A．A soft plastic cup. | B．A pencil eraser. |
| C．A baby milk bottle. | D．A new perfume. |
| A．through mouth or nose | B．through blood transfusion |
| C．by feeling plastic products | D．by heating in the microwave |
| A．A new ban on plastic products. | B．Problems caused by the plastic. |
| C．Good points of the plastic. | D．The use of plasticizers. |

People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (寻求刺激) or imperative (冲动) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.”
【小题1】The research led by Sanbonmatsu indicates that people who multitask __________.
| A．seek high productivity constantly |
| B．prefer handling different things when getting bored |
| C．are more focused when doing many things at a time |
| D．have the poorest results in doing various things at the same time |
| A．assessed the multitasking ability of the students |
| B．evaluated the academic achievements of the students |
| C．analyzed the effects of the participants’ tricky mental tasks |
| D．measured the changes of the students’ understanding ability |
| A．limited power in calculation |
| B．interests in doing things differently |
| C．inability to concentrate on one task |
| D．impulsive desire to try new things |
| A．drive very skillfully |
| B．go in for different tasks |
| C．fail to react quickly to potential dangers |
| D．refuse to explain the reasons for their behavior |

Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．
We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．
【小题1】Which of the following is NOT done by satellites according to the passage?
| A．Sending information for weather forecast |

Societies all over the world name places in similar ways. Quite often there is no official naming ceremony but places tend to be called names as points of reference by people. Then an organized body steps in and gives the place a name. Often it happens that a place has two names: One is named by the people and the other by the government. As in many areas, old habits died hard, and the place continues to be called by its unofficial name long after the meaning is lost.
Many roads and places in Singapore are named in order that the pioneers will be remembered by future generations. Thus we have names such as Stamford Road and Raffles Place. This is in keeping with traditions in many countries ---- in both the West and the East.
Another way of naming places is naming them after other places. Perhaps they were named to promote friendships between the two places or it could be that the people who used to live there were originally from the places that the roads were named after. The mystery is clearer when we see some of the roads named in former British bases. If you step into Selector Airbase you will see Piccadilly Circus ---- obviously named by some homesick Royal Air Force personnel.
Some places were named after the activities that used to go on at those places. Bras Basah Road is an interesting example, “Base Basah” means “wet rice” in Malay. Now why would anyone want to name a road “Wet Rice Road”? The reason is simple. During the pioneering days, wet rice was laid out to dry along this road.
A few roads in Singapore are named by their shapes. There is “Circular Road” for one. Other roads may have parts of their names to describe their shapes, like “ Paya Lebar Crescent”. This road is called a crescent (月牙) because it begins on the main road, makes a crescent and comes back to join the main road again.
【小题1】We learn from Paragraph 1 that _____.
| A．the government is usually the first to name a place |
| B．a ceremony will be held when a place is named |
| C．people prefer the place names given by the government |
| D．many places tend to have more than one name |
| A．Selector Airbase. | B．Raffles Place. |
| C．Piccadilly Circus. | D．Paya Lebar Crescent. |
| A．Change suddenly. | B．Change greatly. |
| C．Disappear very slowly. | D．Disappear quickly. |
| A．after a place | B．after an activity |
| C．after a person | D．by its shape |
| A．The way Singaporeans name their places is unique. |
| B．Some places in Singapore are named for military（军事） purposes. |
| C．Young Singaporeans have forgotten the pioneers. |
| D．Some place names in Singapore are the same as in Britain. |

There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal(激素的) changes that increase feelings of hunger.
In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available.
The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org.
【小题1】Not enough sleep can cause obesity by ______.
| A．burning more of your energy |
| B．making you want to eat more food |
| C．keeping you from doing exercise |
| D．helping you feel great without food |
| A．have your ghrelin level rise and leptin level drop |
| B．have your leptin level rise and ghrelin level drop |
| C．have your ghretin and leptin levels properly balanced |
