China is going green. In order to reduce air pollution and oil shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽車(chē)) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (勻速行駛). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard (車(chē)載的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油門(mén)), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.
小題1:The author writes this passage mainly to________.
A．teach people how to drive a hybrid car
B．introduce a new kind of “green” car
C．show how to save their gasoline when driving a car
D．a(chǎn)nnounce plans to develop hybrid vehicles for China
小題2:Which of the followings is NOT true?
A．The hybrid cars reduce air pollution and oil shortages.
B．The car's gasoline engine doesn't work until it reaches about 24 km/h.
C．This kind of car is completely controlled by an onboard computer.
D．A specially designed battery motor provides extra power when needed.
小題3:What is the most important feature of hybrid cars?
A．They are powered by both a rechargeable battery and gasoline.
B．They are much quieter than traditional cars.
C．They only use 99 percent of their power to run up hills.
D．They have smaller engines than traditional gasoline ones.
小題4:What can we conclude from the story?
A．The batteries can be recharged at any time you want.
B．Using the brake suggests that the gasoline engine should work.
C．The batteries will last for 200, 000 miles without being recharged.
D．The gasoline engine charges the batteries as well as powers the car.

German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.
The paper，published this March in Psychology and Aging，examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96.The surveys were conducted every year from 1993 to 2003.
Survey respondents (受訪(fǎng)者) were asked to estimate their present and future life satisfaction on a scale of 0 to 10，among other questions.
The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction，while middle­aged adults (age 40 to 64) more accurately predicted how they would feel in the future.Adults of 65 and older，however，were far more likely to underestimate their future life satisfaction.Not only did they feel more satisfied than they thought they would，the older pessimists seemed to suffer a lower ratio (比率) of disability and death for the study period.
“We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade，”wrote Frieder R．Lang，a professor at the University of Erlangen­Nuremberg.
Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.
“Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions (預(yù)防措施)，”the authors wrote.
Surprisingly，compared with those in poor health or who had low incomes，respondents who enjoyed good health or income were associated with expecting a greater decline.Also，the researchers said that higher income was related to a greater risk of disability.
The authors of the study noted that there were limitations to their conclusions.Illness，medical treatment and personal loss could also have driven health outcomes.
However，the researchers said a pattern was clear.“We found that from early to late adulthood，individuals adapt their expectations of future life satisfaction from optimistic，to accurate，to pessimistic，”the authors concluded.
小題1:According to the study，who made the most accurate prediction of their future life satisfaction?
A．Optimistic adults.
B．Middle­aged adults.
C．Adults in poor health.
D．Adults of lower income.
小題2:Pessimism may be positive in some way because it causes people________.
A．to fully enjoy their present life
B．to estimate their contribution accurately
C．to take measures against potential risks
D．to value health more highly than wealth
小題3:How do people of higher income see their future?
A．They will earn less money.
B．They will become pessimistic.
C．They will suffer mental illness.
D．They will have less time to enjoy life.
小題4:What is the clear conclusion of the study?
A．Pessimism guarantees chances of survival.
B．Good financial condition leads to good health.
C．Medical treatment determines health outcomes.
D．Expectations of future life satisfaction decline with age.

(2013·宜春五校聯(lián)考)Technology is making life easier for some dairy farmers.They use robotic systems to milk their cows.Cows are trained to follow a series of paths that lead to milking stations.Only one cow at a time can enter a station.
Once inside，the cow is rewarded with food.As the cow eats，a robotic arm cleans and connects the animal to the milking machine.A few minutes later，milking is complete.The gate is opened，the cow is released and the next cow enters.
The robotic systems are designed to operate 24 hours a day.The cows get to decide when they want to be milked.Cows are milked an average of about three times a day.Some are milked four to six times a day.
The cows wear collars around their necks that identify them to the system.A computer keeps records on their eating and milking.A cow is released from the station if the computer decides it should not be milked.
The automated system also measures the temperature and color of freshly produced milk.Milk is thrown away if it does not pass the tests.
Professor Plaut believes the systems will appeal especially to the next generation of farmers.She means young people who are more interested in technology and less interested in working all the time on the farm.Still，she says the price of robotic milking systems will continue to limit their use.
Doug and Tina Suhr have more than 100 cows on their family farm.Last year it became the fourth farm in southeast Minnesota to get a robotic milking system.A recent story in a local agricultural newspaper said the first robot costs 175,000 dollars.The second costs 150,000 dollars.
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot.He says the increase in milk production reaches a high of more than six kilograms per cow per day.
小題1:From the first paragraph，we can infer ________.
A．the robotic system is designed to reduce labor
B．cows can be raised by robots in the future
C．robots direct cows into milking stations
D．cows are kept clean by robots on some farms
小題2:Besides milking cows，the robotic system also can ________.
A．a(chǎn)djust the temperature of milking stations
B．judge the quality of fresh milk
C．improve the appetite of cows
D．keep fresh milk for two weeks
小題3:Why is the robotic system not popular now?
A．Because young people have no interest in it.
B．Because it is difficult to learn how to use it.
C．Because people can't afford to buy it.
D．Because it usually causes the waste of milk.
小題4:According to Doug，what is the wage of an employee per year?
A．$150,000～$175,000.
B．over $75,000.
C．$150,000～$30,000.
D．$30,000～$35,000.

Most parents, I suppose, have had the experience of reading a bedtime story to their children. And they must have        how difficult it is to write a        children's book.  Either the author has aimed too     . , so that the children can't follow what is in his (or more often, her) story,        the story seems to be talking to the readers.
The best children's books are        very difficult nor very simple, and satisfy both the     who hears the story and the adult who         it. Unfortunately, there are in fact       books like this,       the problem of finding the right bedtime story is not        to solve.
This may be why many of books regarded as        of children's literature were in fact written for      . “Alice's Adventure in Wonderland” is perhaps the most        of this.
Children, left for themselves, often      the worst possible interest in literature. Just  leave a child in bookshop or      and he will more  willingly choose the books    in an imaginative way, or have a look at most children's comics ( 連環(huán)畫(huà) ), full of the stories and jokes to which both teachers and right-thinking parents     .
Perhaps we parents should stop trying to persuade children into        our taste in literature. After all children and adults are so       that we parents should not expect that they will enjoy the      books. So I suppose we'll just have to compromise（妥協(xié)） over that bedtime story.

Science Daily—Kids may roll their eyes when their mothers asks them about their school day, but answering her may actually help them learn. New research from Vanderbilt University reveals that children learn the solution to a problem best when they explain it to their mom.
“We knew that children learn well with their moms or with a peer, but we did not know if that was because they were getting feedback and help,” Bethany Rittle-Johnson, the study’s lead author and assistant professor of psychology at Vanderbilt’s Peabody College of education and human development, said. “In this study, we just had the children’s mothers listen, without providing any assistance. We’ve found that by simply listening, a mother helps her child learn.”
Rittle-Johnson believes the new finding can help parents better assist their children with their schoolwork, even when they are not sure of the answer themselves. Although the researchers used children and their mothers in the study, they believe the same results will hold true whether the person is the child’s father, grandparent, or other familiar persons.
“The basic idea is that it is really effective to try to get kids to explain things themselves instead of just telling them the answer,” she said. “Explaining their reasoning, to a parent or perhaps to other people they know, will help them understand the problem and apply what they have learned to other situations. We saw that this simple act of listening by mom made a difference in the quality of the child’s explanations and how well they could solve more difficult problems later on.
小題1:According to the passage, a mom had better ________.
A．give a kid some help when he is explaining his problem
B．just listen while a kid is explaining his problem
C．work together with a kid toward the solution to a problem
D．leave a kid alone when he meets a problem at school
小題2: If she wants to help a child with his schoolwork, a mom ________.
A．should know the answer to a problem first
B．should pay attention to the child’s feedback.
C．may not know the answer herself
D．should not interrupt the child
小題3:Who will be the least help to a kid when he is explaining, according to Rittle-Johnson?
A．The kid’s mom.
B．The kid’s grandmother.
C．A peer.
D．A relative the kid doesn’t know.
小題4:Which of the following best gives the main idea of the passage?
A．Children learn better when their mom is hearing their explaining.
B．Children learn better if they find the solution to a problem themselves.
C．Parents should not provide any assistance to their children’s schoolwork.
D．A mom should listen more to their children when they have problems at school.

Having spent two and a half years in China over several visits, I don’t remember ever going through a phase we in the United States call “cultural shock”. This period of difficulty in adjusting to a new culture would probably have set in during my semester at Peking University. Of course, this is not to say that I didn’t notice any differences between the American and Chinese cultures upon my arrival at Peking University, I did notice the differences. Looking back, I remember one of the first differences I noticed: Chinese universities are surrounded by walls.
To an American, this is one of the most striking aspects of a Chinese university which immediately sets it apart from an American campus. Having grown up in the United States, I had never seen a university surrounded by high, cement(水泥) walls. My idea of a university, based on having seen scores of them in different states of the U.S., was a place of life and learning, an inseparable part of the community in which it was located, open not only to the students of the school itself, but also fully accessible to students from other schools and to the broader public.
My idea of a university was that it was a center of cultural life, a resource for the entire community. In all my twenty-one years, it had never occurred to me that a school would have a wall around it. Walls enclose and separate; schools expand and integrate(合并). The very idea seemed fundamentally incompatible. I asked a Chinese friend if all Chinese universities have walls around them. “You know, I have never really thought about it. I guess so. I guess all Chinese schools have walls around them, not just universities.” “Why?” I asked, “What’s the point?” “I don’t know. To protect us, I suppose.”  “From whom?” “I don’t know. Don’t you have walls around your schools in the United States?” I thought carefully before answering. “No, I’ve never seen or heard of a university encircled by a wall.” My Chinese friend seemed puzzled. Walls around schools came to strike me as more than just an architectural difference between the United States and China. As China continues to open up to the outside world, these walls seem increasingly out of place.
小題1:The author felt strange about Chinese culture when he ___________.
A．studied in Peking University
B．talked with his friends about the walls
C．experienced the “cultural shock” at his arrival
D．spent two and a half years in China over several visits
小題2:In the author’s opinion, a university is a place ___________.
A．where only students can come to study
B．which is similar everywhere in the world
C．that should be surrounded by high cement walls
D．that is an inseparable part of and a resource for the community
小題3:What does the underlined sentence in the last paragraph probably mean?
A．The two ideas are fundamental.
B．The two ideas are basically different.
C．The two ideas about “school” and “wall” are suitable.
D．The two ideas about “school” and “wall” are conflicting.
小題4:What did the author’s friend feel about the walls around universities?
A．He thought it a good idea to have walls encircling schools.
B．He was shocked that American universities are not enclosed.
C．He thought they were necessary to protect students from being hurt.
D．He thought the difference between two countries is only architectural styles.
小題5:We can infer from the passage that the author thinks _____________.
A．walls are really useful in the universities
B．he can never really understand the Chinese culture
C．Chinese universities should work as public scenic spots
D．walls around the universities are inappropriate in an open China

Fear is an emotion like others such as happiness, anger, hurt, sadness. We need emotions to process information we receive and decide how to respond. Being afraid of fast cars, for example, is something that might protect us from harm. Being afraid of the consequence of a choice may prevent us getting into trouble.
Fears in young children commonly center on certain animals like snakes or big dogs. Fears are caused often because of experiences or ideas expressed by others, and at times, the media. Many normal fears during the early years, like men with beards, or large dogs, disappear with age. Those relating to personal failure and ridicule (嘲笑) remain through adulthood and may need special help to overcome.
Children’s fears are often trivial, but that doesn’t mean they should be ignored. They need to be recognized and accepted as real for that child. Only when we help children understand their fears can they grow normally in their ability to deal with them.
Research shows that as a child grows up, the center of his fears changes a lot. Things like divorce, a teacher who “shouted at me”, people with guns, bullies, big boys, or “making fun of me” top the list of childhood fears.
We can not always prevent these experiences from happening, but it’s essential that children be allowed to freely express their emotions without judgment. Sympathy and a caring listener will help ease the pain of these fears. Read books and stories to your child about children who have experienced similar fears. This helps children talk about their fears and find ways to cope. With all emotions, fears become less of a problem for children as they gain self-confidence and they find that fear is normal and can be dealt with.
小題1:According to Paragraph 2, we can know that fears in young children_______.      .
A．only center on frightening animalsB．a(chǎn)re not born but learned
C．can make sure of their safetyD．need special help to deal with
小題2:The underlined word “trivial” in the third paragraph probably means “_______”.
A．smallB．seriousC．harmfulD．common
小題3:In dealing with children’s fears, the final goal of the parents is to _______.
A．stop unpleasant experiences happening to children
B．let children know about the nature of fear
C．create an environment where there is nothing to fear
D．develop children’s ability to treat their fear on their own
小題4:From the passage we can learn that ________ .
A．some childhood fears may have a lasting influence
B．children should avoid the media to reduce their fear
C．fears can be judged according to the environment
D．children with similar fears can communicate easily
小題5:What’s the best title for this passage?
A．How to Overcome Children’s FearsB．Children’s Fears
C．The kind of Children’s FearsD．The Bad Effects of Fears

Researches at Johns  Hopkins University's. Applied Physics laboratory  ( APL)  in Laurel , Maryland have designed a new human-like robot, Its name is Robo Sally. The machine can be controlled from a distance and can he used to do work that is dangerous for human beings.
Roho Sally has two long arms with human-like hands. She can use her fingers to pick up  small objects .examine them in detail and do most things that human hands can do Each finger  contains a tiny motor capable of squeezing 20 pounds of pinch foree ,.enough to defuse a bomb  under the direction of an operator. She sits on a metal base with wheels that let her move around. turn in tight spaces and climb over small objects, .
Mike McLoughlin is the main investigator for the Applied Physics Laboratory's Prosthetics  Program. "The purpose of that program is to develop prosthetic arms that have all the capability  of your natural arms .and you do all the complex motions that we can do with the natural arm- with the robot. "
It was a difficult job. Mr. McLoughlin says the device had to have many small motors to。 have the ability to do what a human hand does; It  also needs to have human-like strength. The  thumb was especially difficult because it permits the hand .to hold objects. And everything had.   to fit into a space about the size of a human hand.
The next problem  .he says .was to figure out how to control the artificial hand. " So we had   to figure out how to make the connection between the brain and this arm.
For search-and-rescue duties.Roho Sally will be operated by a human being using a wire- less machine that is far from the robot. The operator will also wear special gloves and glasses.  The glasses permit the operator to see the robot's hands .even though they are far away.
Mr. McLoughlin says this kind of robots could be used in what he calls "dull , dirty or dan- gerous" situations where fine human finger movements are required. He says the technology is  not ready for everyday application .but he predicts that within five years we will see some won-  derful improvements.
小題1:The underlined word " defuse"  in Paragraph 2 is closest in meaning to "_________".
A．removeB．discoverC．equipD．produce
小題2:According to Paragraph 2.which picture is Robo Sally?

小題3:What can we learn ahout the prosthetic arms according to the passage?
A．They are expected to function as well as natural ones.
B．They have many large motors controlled by robots.
C．They have human-like strength to control the robot.
D．They are connected with human brains.
小題4:Which of the following is true about Robo Sally according to Mr. McLoughlin?
A . Its operator doesn't need  any  equipment.
B. It has been Widely used in everyday life in the USA.
C. It can work in situations which are dangerous for humans.

The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological（生態(tài)的） disaster area. Nauru’s heartbreaking story could have one good consequence — other countries might learn from its mistakes.
For thousands of years, Polynesian people lived the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.
However, because it was very remote, Nauru had little communication with Europeans at first. The whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1,400 to 900.
Nauru’s real troubles began in 1899 when a British mining company discovered phosphate (磷酸鹽)on the island. In fact, it found that the island of Nauru was nearly all phosphate, which a very important fertilizer for farming. The company began mining the phosphate.
A phosphate mine is not a hole in the ground; it is a strip mine（帶狀礦）. When a company strip-mines, it removes the top layer（層） of soil. Then it takes away the material it wants. Strip mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.
In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.
Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem — their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was financially ruined. Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island. This will probably never happen.
小題1:What might be the author’s purpose in writing the text?
A．To seek help for Nauru’s problems.B．To give a warning to other countries.
C．To show the importance of money.D．To tell a heartbreaking story of a war.
小題2:What was Nauru like before the Europeans came?
A．Rich and powerful. B．Modern and open.
C．Peaceful and attractive. D．Greedy and aggressive.
小題3:The ecological disaster in Nauru resulted from           .
A．soil pollutionB．phosphate over mining
C．farming activity D．whale hunting
小題4:Which of the following was a cause of Nauru’s financial problem?
A．Its leaders misused the money.B．It spent too much repairing the island.
C．Its phosphate mining cost much money.D．It lost millions of dollars in the civil war.
小題5:What can we learn about Nauru from the last paragraph?
A．The phosphate mines were destroyed.B．The leaders will take the experts’ words seriously.
C．The island was abandoned by the Nauruans.D．The ecological damage is difficult to repair.
