For years we have been told that encouraging a child’s self-respect is important to his or her success in life. But child experts are now learning that too much praise can lead to the opposite effect. Praise-aholic kids who expect it at every turn may become teens who seek the same kind of approval from their friends when asked if they want to go in the backseat of the car.
The implication(含义) of saying “You are the prettiest girl in class,” or talking about the goals she scored but not her overall effort, is that you love her only when she looks the best, scores the highest, achieves the most. And this carries over to the classroom.
Social psychologist Carol Dweck, PHD, tested the effects of over-praise on 400 fifth graders while she was at Columbia University. She found that kids praised for “trying hard” did better on tests and were more likely to take on difficult assignments than those praised for being “smart”.
“Praising attributes(品质) or abilities makes a false promise that success will come to you because you have that quality, and it devalues effort, so children are afraid to take on challenges,” says Dweck, now at Stanford University, “They figure they’d better quit while they’re ahead.”
【小题1】The underlined words “Praise-aholic kids” refer to kids who are ______.
| A．tired of being praised | B．worthy of being praised |
| C．very proud of being praised | D．extremely fond of being praised |
| A．better-known | B．better-organized |
| C．more persuasive | D．more interesting |
| A．praise for efforts should be more encouraged |
| B．praise for results works better than praise for efforts |
| C．praising a child’s achievements benefits his or her success in life |
| D．praising a child’s abilities encourages him or her to take on challenges |
【小题1】D
【小题2】C
【小题3】A

High-tech machines have made life easier for millions around the world. However, some people still prefer low-tech ways of doing things. Here’s an example of why this is happening. You can microwave a frozen hamburger in 60 seconds. However, it won’t taste as good as one you cook on the stove. And if you’re in that much of a hurry, you probably won’t take time to toast the bun. High-tech cooking saves time, but it doesn’t make for better-tasting meals.
Most people get their news from high-tech sources like television or the Internet. This has many advantages. For example, electronic news is more up to date than newspapers or magazines. It’s also more exciting to see live and videotaped news events than photographs. However, newspapers and magazines have some important advantages. They give more background and details. They also let you read the parts that are important to you and skip the rest.
Other high-tech timesavers have similar disadvantages. For examples, most people use the phone or e-mail to stay in touch with friends and family members who live in other places. But when you use the Internet or the phone, you don’t always think carefully about what you are saying, and sometimes you forget the important things you want to communicate. Similarly, when you word-process a homework assignment instead of handwriting it, you can check your spelling electronically and put in fancy headings. However, some students are so busy with the computer that they don’t pay enough attention to the actual words they are writing.
【小题1】Which of the following statements is TRUE according to the passage?
| A．The writer likes high-tech cooking. |
| B．Low-tech cooking produces better-tasting meals. |
| C．High-tech news programs always keep you reading what is important to you. |
| D．Handwritten homework is better than word-processed homework. |
| A．Better late than never. | B．Easy come, easy go. |
| C．Every coin has two sides. | D．Learn to walk before you run. |
| A．High-tech vs. low-tech |
| B．Advantages vs. disadvantages. |
| C．Newspapers and magazines vs. television and the Internet. |
| D．Word-processing vs. handwriting. |

Batteries can power anything from small sensors to large systems．While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves．University of Missouri（MU） researchers are developing a nuclear energy source that is smaller, lighter and more efficient．
“To provide enough power, we need certain methods with high energy density（密度）”，said Jae Kwon, assistant professor of electrical and computer engineering at MU．“The radioisotope（放射性同位素） battery can provide power density that is much higher than chemical batteries．”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems （M/NEMS）．Although nuclear batteries can cause concerns, Kwon said they are safe．
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems．”
His new idea is not only in the battery’s size, but also in its semiconductor（半导体）．Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor．
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure（晶体结构） of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem．”
Together with J．David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery．In the future, they hope to increase the battery’s power, shrink its size and try with various other materials．Kwon said that battery could be thinner than the thickness of human hair
【小题1】The text is most probably a ________．
| A．science news report | B．book review |
| C．newspaper ad | D．science fiction |
| A．get rid of the radioactive waste |
| B．test the power of nuclear batteries |
| C．decrease the size of nuclear batteries |
| D．reduce the damage to lattice structure |
| A．uses a solid semiconductor | B．will soon replace the present ones |
| C．could be extremely thin | D．has passed the final test |
| A．to show chemical batteries are widely applied |
| B．to introduce nuclear batteries can be safely used |
| C．to describe a nuclear-powered system |
| D．to introduce various energy sources |

Legends about the development of coffee are varied and interesting, involving chance occurrences, political tricks, and the pursuit of wealth and power.
According to one story, a sheepherder named Kaldi, as he tended his sheep, noticed the effect of coffee beans. He noticed that the sheep became excited after eating the red “cherries" from a certain plant when they changed pastures (牧场). He tried it himself, and was soon as overactive as his sheep. Another story relates that a monk happened to discover that this fruit from the shiny green plant could help him stay awake.
Another legend gives us the name for coffee, “mocha”. Omar, an Arabian was thrown to the desert with his followers to die of starvation. In desperation, Omar had his friends boil and eat the fruit from an unknown plant. Not only did the soup save the group, but the residents of the nearest town, Mocha, took their survival as a religious sign. The plant and its beverage (饮料) were named Mocha to honor this event.
Coffee was introduced much later to countries beyond Arabia, whose inhabitants believed it to be a tasty thing and guarded its secret as if they were top secret military plans. The government forbade transportation of the plant out of the Moslem nations. The actual spread of coffee was started illegally. One Arab named Baba Budan smuggled (走私) beans to some mountains near Mysore, India, and started a farm there. Early in this century, some of those original plants were found still growing fruitfully in the region.
Coffee today is grown and enjoyed worldwide, and is one of the few crops that small farmers in third-world countries can profitably export.
【小题1】What does the second paragraph mainly talk about?
| A．A sheepherder used coffee beans to keep sheep excited. |
| B．Coffee was a special kind of red cherry from a certain plant. |
| C．A sheepherder and a monk accidently discovered coffee’s effect. |
| D．Sheep ate a lot of coffee beans while they changed pastures. |
| A．Kaldi’s story. | B．The monk’s story. |
| C．Omar’s story. | D．Baba Budan’s story. |
| A．a town | B．an Arabian | C．a kind of coffee | D．a sheepherder |
| A．The Secret of Coffee | B．The Tales of Coffee |
| C．People’s Love for Coffee | D．The Function of Coffee |

Can a fish hear fishermen moving along the stream? What are the facts about the ability of a fish to see? Can they tell the difference between colors?
The sharp hearing of a fish has been proved by two scientists, who trained a fish to expect its food when it heard the sound of a whistle. And a slight sound two hundred feet away could drive fishes away. That should make fishermen start thinking.
One scientist had made experiments to prove fish can recognize different colors such as red, brown, yellow and green.
Fish also have an eye for different shapes. One scientist proved this by teaching fish to connect certain patterns with food. He used a small circle and a square. If the fish swam towards the circle, they received food as a reward. If they swam towards the square, they received nothing. The fish learned in time to go to the circle but not to the square. Does this mean that in time fish might learn to leave alone all food on hooks that they have seen often before? Here is something for all fishermen to think about!
These facts help to make more believable some of the “believe it or not” stories that have been told about fish. It is clear that fish have sometimes shown their ability to gain knowledge as man does. A good example of what we might call “thinking” by a fish is given by an experience of Dr. Andrew Gage. Fishing over a bridge, he hooked a fish. It struggled and dragged the line two hundred feet away before he stopped it. Then it swam back to the bridge. The clever fish then swam round a pile and, with a sudden push, broke the line. If the story ended there, one could say that the fish had freed itself by chance. However, Gage went on fishing. Below him he could see the fish that had broken loose. After another twenty minutes the fish again seized the food on the hook. This time it did not swim out but swam round one of the piles and again broke the line.
Many stories are told of the fish that get away and the clever “old hand” ones that can’t be caught. The more often a fish is nearly caught, the more difficult it will be to interest it next time.
【小题1】The last two paragraph’s mainly discuss _________.
| A．whether a fish can think as man does |
| B．how a fish could escape from danger |
| C．how to catch a fish more easily |
| D．whether a fish is believable |
| A．Fish can hear and see |
| B．How clever is a fish? |
| C．Fish can play tricks |
| D．How scientists help fishermen. |
| A．it’s difficult to catch fish; |
| B．fish are cleverer sometimes than fishermen |
| C．fish seem to learn by their experience |
| D．fewer people will be interested in fish |

You’ve bought what you need. The grocery cashier asks, “Will that be paper or plastic? You reply “Plastic, please.”
This seems like a simple question and there are plenty of reasons we choose plastic: easier to carry, lighter than paper bags, possibly less damaging to the environment, less expensive to the shop owners, able to be used as trash bag, and so on. There are different opinions on plastic and paper. Now let’s follow the travels of 3 plastic bags. It begins at the grocery store with the customer’s choice.
Plastic Bag 1: As the waste engineer come by and pick up the trash, the first plastic bag falls out. It sits on a small street for a couple of hours until a car comes along and takes it down to the road. Then a gust of wind blows it across the road, then another car, then another gust of wind finally makes its way to the beach. Water fills the plastic bag and makes it look like a jellyfish. A seal(海豹) swims by, thinking it looks very interesting, and swallowed it. The plastic bag may stay in the seal’s stomach for months, maybe years. You see, our lovely animals have been living thousands of years in a world where everything can be eaten.
Plastic Bag 2: This bag does make its way to landfill(垃圾场). Before they have a chance to cover up the thousands of pounds of daily waste, a strong wind comes up and blows these plastic bags out of the landfill. Once the wind stops, workers will be sent to collect thousands of bags around. But they can’t possibly get them all. So our little bag continues his adventure getting caught in trees, eaten by birds or making its way to our lakes or rivers.
Plastic Bag 3: The last bag also blows away but is caught in a landfill where it sits for many years, as all the trash is wrapped in a big plastic bag, making natural degradation(降解) impossible. Although workers do much work to make sure water and air system won’t be polluted, some do. Guess what, plastic bags are made from petrol, a harmful waste material, which in one way or another makes its way to the environment.
Another problem with putting plastic bags in out trash is that our landfills for most cities may be filled in about 20 years. More importantly, since we are running out of land to build homes, you might have the pleasure of one day living on top of your plastic bags!
One of the best suggestions is not to use a bag at all or bring your own cloth bags. If you must, please choose paper bags, which, though not suggested, can be eaten by animals. And there are more opportunities recycle paper bags. It does take a little extra effort. But please have a thought about the little seal next time you say, “Plastic please.”
【小题1】According to the passage, what is NOT the reason for a customer to choose plastic bags?
| A．He can use plastic bags to carry trash later. |
| B．He finds paper bags heavier than plastic bags. |
| C．He finds plastic bags more convenient to carry. |
| D．He can save money for plastic bags are cheaper. |
| A．seals like eating plastic bags around them. |
| B．seals really have a good stomach. |
| C．seals are potential victims of plastic bags. |
| D．seals are not able to differ plastic from food. |
| A．still does harm to the environment |
| B．can hardly be harmful to the environment |
| C．is much safer than Plastic Bag2 |
| D．will end up being eaten by seals or some fish |
| A．Suggestions on reducing harm of plastic bags. |
| B．Disadvantages of using too many plastic bags. |
| C．Persuading people into using paper bags. |
| D．Other potential victims of plastic bags. |
| A．Excited | B．Serious | C．Ironical | D．Casual |

Risk of death is 3.5 t0 5 times greater for obese smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 t0 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 t0 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
Taking Charge of Your Health
Making healthy choices can be difficult when we're constantly bombarded with products that are hazardous to our health, but it's not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you're an overweight smoker worried about gaining weight due to quitting, take heart. It's never too late to change your course and even reverse damage to some extent.
【小题1】What is the probably the best title of the text?
A. Obese smoking and death B. Key findings about smoking
C Taking charge of your health D. Obesity and smoking
【小题2】Which of the following is true according to the text?
| A．Obese smokers are less likely to suffer from cancer |
| B．Obese smokers are more likely to suffer from cancer |
| C．Obese smokers .tend to gain fewer body mass index. |
| D．Obese smokers tend to get heavier than those Who never smoke |
| A．easy and possible | B．difficult and impossible |
| C．easy ant worthwhile | D．difficult but worthwhile |
| A．To inform the readers of the findings about obese smoking. |

WASHINGTON—Two-thirds of the world’s polar bear population could be gone by 2050 if predictions of melting sea ice hold true, the US Geological Survey reported on Friday.
The fate of polar bears could be even worse than that estimate, because sea ice in the Arctic might be disappearing faster than the available computer models predict, the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species.
“There is a definite link between changes in the sea ice and the welfare of polar bears,” said Steve Amstrup, who led the research team. He says Arctic sea ice is already at the lowest this year and is expected to retreat(退却) farther this month.
That means that polar bears—some 16,000 of them -- will disappear by 2050 from parts of the Arctic where sea ice is melting most rapidly, along the north coasts of Alaska and Russia, researchers said in a telephone briefing(简报).
Other polar bears could survive beyond that date but many of those could be gone by 2100, Amstrup said. By this century’s end, the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland.
“It is likely to result in loss of approximately two-thirds of the world’s current polar bear population by the mid 21st century,” the report’s executive summary said.
“Because the observed trajectory(轨迹)of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative(保守的).”
In January, the US Fish and Wildlife Service proposed listing the polar bear as a threatened species, noting polar bears depend on sea ice as a platform to hunt seals, their main food.
Without enough sea ice, polar bears would be forced onto land, but they are poor hunters once they get out of the water and ice, the researchers said. The bears’ disappearance would probably take place as young cubs(幼兽)failed to survive to adulthood and females were unable to reproduce successfully.
【小题1】What was the US Geological Survey intended to do?
| A．To determine whether the polar bear was in danger. |
| B．To measure how fast the sea ice melts in the Arctic. |
| C．To check the predictions of the computer models. |
| D．To find out the exact number of the polar bear. |
| A．The pollution of the Arctic region. | B．The sea ice melting at high speed |
| C．Fewer food sources being left. | D．The temperature getting colder. |
| A．help young polar bears to survive the cold winter |
| B．have large number of seals living in the oceans |
| C．make sure there is enough sea ice in the Arctic |
| D．provide chances for adult polar bears to reproduce |

It's such a happylooking library, painted yellow, decorated with palmtree stickers and sheltered from the Florida sun by its own roof. About the size of a microwave oven, it's pedestrianfriendly, too, waiting for book lovers next to a sidewalk in Palm Beach Country Estates, along the northern boundary of Palm Beach Gardens.
It's a library built with love.
A year ago, shortly after Janey Henriksen saw a Brian Williams report about the Little Free Library organization, a Wisconsinbased nonprofit that aims to promote literacy and build a sense of community in a neighborhood by making books freely available, she announced to her family of four, “That's what we're going to do for our spring break！”
Son Austin, now a 10thgrader, didn't see the point of building a library that resembles a mailbox. But Janey insisted, and husband Peter unwillingly got to work. The 51yearold owner of a ship supply company modified a small wooden house that he'd built years earlier for daughter Abbie's toy horses, and made a door of glass.
After adding the library's final touches(装点), the family hung a signboard on the front, instructing users to “take a book, return a book，” and making the Henriksen library, now one of several hundred like it nationwide and among more than 2,500 in the world, the only Little Free Library in Palm Beach County.
They stocked it with 20 or so books they'd already read, a mix of science fiction, reference titles, novels and kids' favorites. “I told them, keep in mind that you might not see it again，” said Janey, a stayathome mom.
Since then, the collection keeps replenishing(补充) itself, thanks to ongoing donations from borrowers. The library now gets an average of five visits a day.
The project's best payoff, says Peter, are the thankyou notes left behind. “We had no idea in the beginning that it would be so popular.”
【小题1】In what way is the library “pedestrianfriendly”？
| A．It owns a yellow roof. |
| B．It stands near a sidewalk. |
| C．It protects book lovers from the sun. |
| D．It uses palmtree stickers as decorations. |
| A．a visit to Brian Williams |
| B．a spring break with her family |
| C．a book sent by one of her neighbors |
| D．a report on a Wisconsinbased organization |
| A．by a ship supply company |
| B．on the basis of toy horses |
| C．like a mailbox |
| D．with glass |
| A．It was made by a user of the library. |
| B．It marked a final touch to the library. |
| C．It aimed at making the library last long. |
| D．It indicated the library was a family property. |
| A．donate books to the library |
| B．get paid to collect books for the library |
| C．receive thankyou notes for using the library |
| D．visit the library over 5 times on average daily |
