Many animal and plant species have become extinct (灭绝的) and many more are in critical danger.
Dodo
The Dodo is a classic example of how human caused damage to the earth's biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and last one was killed in 1681.
Rhinos
The Rhino (犀牛) horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves(保护区). Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers(偷猎者).
The Giant Panda
The future of the Giant Panda is far from certain. As few as 1,000 remain in the wild. The Chinese government has set up 33 panda reserves to protect these beautiful animals. However, The panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose(造成)one of the most serious threats to the animals continued existence.
Whales
Despite the fact that one-third the world's oceans have been declared whale sanctuaries(保护区), 7 out of 13 whale species remain endangered. Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions(碰撞)with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.
Tigers
The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5,000 and 7,000 and The Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tigers’ bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.

Anyone who doubts that children are born with a healthy amount of ambition need spend only a few minutes with a baby eagerly learning to walk. No matter how many times the little ones stumble in their first efforts, most keep on trying, determined to master their amazing new skill. It is only several years later, many psychologists and teachers agree, that a good number of kids seem to lose their natural drive to succeed. For the parents of such kids, whose own ambition is often tied to their children’s success, it can be a painful experience.
Figuring out why the fire went out is the first step. Assuming that a kid doesn’t suffer from a learning disability, or isn’t involved in some family crisis(危机) at home, many educators attribute a sudden lack of motivation to a fear of failure or classmate pressure. “Everything is within the kids’ control; their intelligence is changeable,” says Lisa Blackwell, a research scientist at Columbia University. More than any teacher or workshop, Blackwell says, “parents can play a key role in conveying this message to their children by praising their effort, and progress rather than emphasizing their ‘smartness’ or praising high performance alone. Most of all, parents should let their kids know that mistakes are a part of learning.”
Some experts say our education system, with its strong emphasis on testing and separation of students into different levels of ability, also bears blame for the disappearance of drive in some kids. “These programs shut down the motivation of all kids who aren’t considered gifted and talented. They destroy their confidence,” says Jeff Howard, a social psychologist. Howard and other educators say it’s important to expose kids to a world beyond homework and tests, through volunteer work, sports, hobbies and other extracurriculum activities.
“The problem of the issue is that many students experience education as irrelevant to their life goals and ambitions,” says Michael Nakkual, a Harvard education professor. The key to getting kids to aim higher at school is to free them of the idea that class work is irrelevant, to show them how doing well at school can actually help them fulfill their dreams beyond it. They need to understand that you have to learn to walk before you can run.
46.According to the passage, the parents of kids with no ambition .
A.don’t do a very good job teaching them to walk
B.are to blame if the kids do poorly in school
C.feel pain because ambitions are connected to their success
D.should take part in extracurriculum activities with kids
47.The underlined part “the fire went out” probably means .
A.the motivation was suddenly lost
B.the fear of failure was suddenly gone
C.the learning disability was suddenly lost
D.the fire was suddenly gone
48.All the following can contribute to a sudden lack of ambition except .
A.learning disability B.classmate pressure
C.emphasis on testing D.extracurricular activities
49.What is the most important thing for parents in motivating their kids?
A.By punishing kids who don’t display ambition.
B.By emphasizing smartness and high performance.
C.By telling kids that mistakes are a part of learning.
D.By praising the effort and progress they have made.
50.We can infer from the passage that .
A.children who have lost their ambition will never succeed in life
B.school performance has much to do with students’ later success
C.both the parents and the school are to blame for the lost ambition
D.younger kids learning to walk are more ambitious than older ones

As I was reading a recent story in Slate on 20-somethings complaining about how the economy was ruining their life plans, I couldn’t help but think the 20-somethings sounded like a bunch of spoiled children who grew up expecting everything to be easy for them. As a 20-something myself, I certainly share their disappointment: my husband and I probably won’t be able to buy a house until we’re in our 40s, and we too are burdened by student loans(贷款). But why should it be any different? Being young persons in America, shouldn’t they take up all of the challenges and opportunities that this country offers?
Consider some of these views shared in the Slate story: Jennifer, 29, owner of a two-bedroom apartment with her husband, worries that she won’t be able to have children for at least a decade because they can’t afford to buy a house yet.
I read that, and I thought, what planet is she living on where you need to own a house in order to have kids? Has she ever visited a developing country, or even downtown areas in this one? Home ownership is a luxury(奢华), not a fertility requirement.
A 26-year-old in the story despairs(绝望) that he can’t afford to get a Ph.D. in literature. Well, that sounds a bit like expressing disappointment that no one will pay you to write poetry on the beach in Thailand for five years.
Yes, it’s sad that these young people feel so lost. But I think the problem is their extremely high expectations, not economic reality. Beth Kobliner, author of Get a Financial Life: Personal Finance in Your Twenties and Thirties, says that she thinks people’s expectations are slowly adjusting, but today’s 20-somethings grew up at a time when everyone’s wealth appeared to be expanding. Their parents probably saw their home values rise along with their investments. “So you have people who have grown up in an environment where people had great expectations of what living well means,” says Kobliner.
This recession(衰退) will certainly play a role in forcing those expectations into more realistic group. In the meantime, it seems a lot better for our mental health to focus on being grateful-for our one-bedroom apartments, for living in modern cities, or perhaps just for being able to eat three meals a day-than on longing for some kind of luxury life.
41.What makes the author think the 20-somethings sound like a bunch of spoiled children?
A.They expect everything to be easy for them.
B.They complain that the economy is spoiling their life plans.
C.They are reluctant to face all of the challenges.
D.They are burdened by student loans.
42.The underlined word “fertility” in Paragraph 3 probably means .
A.baby production B.pleasant
C.baby comfort D.essential
43.Which of the following is not one of the complaints of the 20-somethings?
A.They can’t have children for at least a decade to buy a house.
B.They have only one-bedroom apartment to live in.
C.They can’t buy a house until 40 because of student loans.
D.They despair at not being able to afford a Ph.D. in literature.
44.What’s the author’s attitude towards the 20-somthings with high expectation in Paragraph 5?
A.Intolerant.
B.Negative.
C.Unbelieving.
D.Understanding.
45.What is the best title for this passage?
A.How Young People Afford to Continue Their Study
B.Why Young People Can’t Afford to Buy a House
C.When Young People’s High Hopes Create Despair
D.What the 20-somethings’ High Expectations Are

Limit the use of private cars, improve public transport and encourage the use of bicycles to control traffic congestion(拥挤) during the 2008 Olympics, experts from foreign countries advised Beijing on Friday.
Professor Nigel Wilson, of the civil and environmental engineering department of Massachusetts Institute of Technology, said he was "supportive to the limiting of private cars during the Olympic Games", saying that in foreign countries, the method is also adopted during big events, but he was unsure about the approach.
The government planned to keep an average of more than one million cars off the roads to improve traffic flow during the Olympics, said Liu Xiaoming, deputy director of the Beijing Traffic Committee, at the China Planning Network First Urban Transportation Congress.
Sharing Wilson's view, Dr. Yoshitsugu Hayashi, dean of the Graduate School of Environmental Studies of Nagoya University, believed the reduction in car use should be achieved not by banning, but through incentives.
"Drivers who don't use their private cars could be given points," he said, "and the points could be exchanged for goods from online shopping."
Wetzel stressed limiting the use of company cars. "Governmental officials should also be encouraged to use public transportation or ride bicycles," he said, adding that he himself is a bicycle-rider in London.
Matthew Martimo, director of Traffic Engineering with Citilabs, said the bicycle was China's advantage. "Limiting private cars is an idea worth trying but it is just a temporary solution," he said. "The real cause of congestion is high density of people in Beijing and many have cars."
Beijing, with a population of 15 million, is home to more than three million automobiles, and the number is rising by 1,000 a day.
Professor Wilson said the Olympic Games was a great opportunity for Beijing to think about traffic problems and develop transportation, adding that the city had already been making public transport more efficient. Beijing has promised to stretch its 114-kilometer city railway to 200 kilometers before the opening of the Olympic Games.
“We are looking forward to borrowing Beijing's experiences and drawing from its lessons in preparation for the 2012 Olympics,” said Wetzel.
51. The underlined word incentives in paragraph 4 means_______.
A. something that encourages people to try B. online shopping
C. points could be exchanged for goods D. award
52.It can be seen from the passage that ______.
A. the government planned to forbid over 1 million cars to run on the roads during the Olympics.
B. banning private cars is the best way to solve traffic congestion in Beijing
C. Beijing now has 200 kilometers of city railway
D. the use of company cars will not be limited
53. Why did Wetzel stress “ he himself is a bicycle-rider in London”?
A. To limit the use of company cars.
B. To encourage governmental officials to use public transportation or ride bicycles.
C. To show that riding bicycles is good for health.
D. To show that he loves riding bicycles.
54. Which of the following may be the reason for the traffic congestion in Beijing?
A. The 2008 Beijing Olympic games.
B. The number of cars in Beijing is rising by 1,000 a day.
C. The large population in Beijing and the large number of cars.
D. Public transport in Beijing is not efficient.
55. The purpose of the passage is ________.
A. to limit the use of private cars, improve public transport
B. to encourage the use of bicycles to control traffic congestion during the 2008 Olympics
C. to borrow Beijing's experiences and draw from its lessons in preparation for the 2012 Olympics
D. to tell the advice given by foreign experts on traffic congestion during 2008 Beijing Olympics

It had been some time since Jack had seen the old man. College, carrier, and life itself got in the way. In fact, Jack moved clear across the country in pursuit of the dreams. There, in the rush of his busy life, Jack had little time to think about the past and often no time to spend with his wife and son. He was working on his future, and nothing could stop him.
Over the phone, his mother told him, “Mr. Belser died last night. The funeral is Wednesday.” Memories fleshed through his mind like an old newsreel as he sat quietly remembering his childhood days.
“Jack, did you hear me?”
“Oh, sorry, Mom. Yes, I heard you. it’s been so long since I thought of him. I’m sorry, but I honestly thought he died years ago,” Jack said.
“Well, he didn’t forget you. Every time I saw him he’d ask how you were doing. He’d reminisce (回忆) about the many days you spent over ‘his side of the fence’ as he put it, ” Mom told him.
“I loved that old house he lived in,” Jack said.
“You know, Jack, after your father died, Mr. Belser stepped in to make sure you had a man’s influence in your life,” she said.
“He’s the one who taught me carpentry. I wouldn’t be in this business if it weren’t for him. He spent a lot of time teaching me things he thought were important. Mom, I’ll be there for the funeral.” Jack said.
Busy as he was, he kept his word. Jack caught the next flight to his hometown. Mr. Belser’s funeral was small and uneventful. He had no children of his own, and most of his relatives had passed away.
The night before he had to return home, Jack and his Mom stopped by to see the old house next door one more time, which was exactly as he remembered. Every step held memories. Every picture, every piece of furniture … Jack stopped suddenly.
“What’s wrong, Jack?” his Mom asked.
“The box is gone,” he said.
“What box?” Mom asked.
“There was a small gold box that he kept locked on top of his desk. I must have asked him a thousand times what was inside. All he’d ever tell me was ‘the thing I value most’,” Jack said.
It was gone. Everything about the house was exactly how Jack remembered it, except for the box. He figured someone from the Belser family had taken it.
“Now I’ll never know what was so valuable to him,” Jack said sadly.
Returning to his office the next day, he found a package on his desk. The return address caught his attention.
“Mr. Harold Belser” it read.
Jack tore open the package. There inside was the gold box and an envelope. Jack’s hands shook as he read the note inside,
“Upon my death, please forward this box and its contents to Jack Bernett. It’s the thing I valued most in my life.” A small key was taped to the letter. His heart racing, and tears filling his eyes. Jack carefully unlocked the box. There inside he found a beautiful gold pocket watch. Running his fingers slowly over the fine cover, he opened it.
Inside he found these words carved: “Jack. Thanks for your time! Harold Belser.”
“Oh. My God! This is the thing he valued most …”
Jack held the watch for a few minutes, then called his assistant and cleared his appointments for the next two days. “Why?” his assistant asked.
“I need some time to spend with my son,” he said.
46. Why did Jack think Mr. Belser died years ago?

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically(身体上).
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
51. From Paragraph 1, we learn that ________.
A. diet products fail to bring out people’s potential
B. people have difficulty in choosing diet products
C. diet products are misleading people
D. people are fed up with diet products
52. One psychological effect of diet products is that people tend to _____.
A. try out a variety of diet foods
B. hesitate before they enjoy diet foods
C. pay attention to their own eating habits
D. watch their weight rather than their diet
53. In Paragraph 3, “gain comes without pain” probably means ______.
A. losing weight is effortless
B. it costs a lot to lose weight
C. diet products bring no pain
D. diet products are free from calories
54. Diet products indirectly harm people physically because such products ______.
A. are over-consumed
B. lack basic nutrients
C. are short of chemicals
D. provide too much energy
55. Which of the following shows the structure of the passage?
