Running like the wind, roaring （咆哮） like thunder, tigers have long been feared and respected as a king of the animal world．But last week a report said that there are no more than 30 wild tigers left in south China．
This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund．
The South China tiger, also known as the Chinese tiger, is native to southern China．In the 1950's, there were over 4000 tigers found in mountain forests in the country．But due to the destruction of their natural habitat （栖息地） and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species．
Sixty-six of the big cats can be found in the cages of a dozen zoos around China．But they are nothing like their wild cousins．They have lost their natural skills such as hunting and killing．If they were set free they could not look after themselves．
"Breeding has damaged the quality of the species", said Pei Enle, deputy director of the Shanghai Zoo．
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa．Four of them have already arrived．Progress has been made as two elder tigers have recovered some of their instincts（本能） and can hunt wild animals by themselves at the African base．
" South Africans are very experienced in reintroducing big animals to the wild．The country has very good natural conditions for the tigers to learn in", said Lu Jun, office director of the National Wildlife Research and Development Center．" We tried in Fujian Province, but it was not successful as there was not a complete eco-chain（生物链） and there was a lack of space．"
The tigers should return to China in 2007 when the reservations in Fujian are ready．

1.
What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?
1. A.
  Because it has lost its natural instincts．
2. B.
  Because there is not a complete eco-chain．
3. C.
  Because there is no space for it．
4. D.
  Because uncontrolled hunting has destroyed its natural living conditions．
2.
How is the programme of sending several tigers to South Africa getting on?
1. A.
  Its effect still remains to be seen．
2. B.
  Two tigers can already compete with their wild cousins．
3. C.
  Some of the tigers are already on the road to recovering their natural skills．
4. D.
  The tigers should be able to recover their instincts completely by 2007．
3.
By saying " but they are nothing like their wild cousins", the writer means that ______．
1. A.
  they are no longer feared by other wild animals
2. B.
  they don't know how to hunt or kill
3. C.
  a complete change has resulted in the species because of breeding
4. D.
  to reintroduce them into the wild has become an urgent task
4.
What is the purpose of sending young tigers to South Africa?
1. A.
  To help the tigers recover their ability to live in the wild．
2. B.
  To provide them with a better environment．
3. C.
  To get the tigers to go on a tour．
4. D.
  To find a complete eco-chain for them．
5.
Which one is not the reason for South Africa being chosen as the training place?
1. A.
  Because the tigers can hunt wild animals by themselves at the African base．
2. B.
  Because South Africans are skilled at dealing with the tigers．
3. C.
  Because there is a complete eco-chain and enough space there．
4. D.
  Because the country has good natural conditions for the tigers to learn in．

There’s a time to get angry, and it’s best for your child if you do. Let’s say your child hits a playmate with a toy hard enough to make the other child cry. How can you teach your child to feel sorry so he or she won’t do it again? Researchers say the best way for parents to react（反应）is to show their anger and to let the child know exactly why they are mad.
Many parents believe that it is best to control their feelings and to wait until they’re calm before scolding their children. But the mother or father who explains reasonably to a child , “Peter was crying because you hit him,” is not likely to attract much attention. Young children need to be scolded immediately, and strongly, before they’ll take criticism （批评）to heart.
When your young child does something wrong, scold him or her seriously at once. At the same time be sure to tell the child clearly what he or she has done wrong. An angry reaction without an immediate explanation does little good. Forbidding a child to play outside or not allowing him to watch TV as a punishment works well-but only when taken together with an explanation. Make sure your child understands that although his or her wrongdoing has made you angry, you still love him or her. Use simple, direct words such as, “You hurt peter. How would you feel if he hit you? You must never, never hurt people.” If your voice expresses strong feeling clearly, your message will carry enough weight.

1.
According to researchers, how should parents react when their child did something wrong?
1. A.
  Ask the child not to do it again any time.
2. B.
  Show the child how angry they are and tell him why.
3. C.
  Teach the child why and how to say sorry to others.
4. D.
  Let the child know you still love hime or her.
2.
What do many parents think they should do with the wrongdoer?
1. A.
  Calm themselves down before scolding him.
2. B.
  Hide their feelings when talking to him.
3. C.
  Explain immediately why he was wrong.
4. D.
  Speak strongly and angrily to him.
3.
What could be the best title for the text?
1. A.
  Different Ways to Deal with Children’s Wrongdoings
2. B.
  Differences among Parents in Dealing with Children
3. C.
  Best Ways to Stop Children’s Wrongdoings

A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment.
The unpunctual man, on one hand, never does what he has to do at the proper time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be regained. Time is more valuable than material things. In fact, time is life itself. The unpunctual man is for ever wasting and mismanaging his most valuable asset (财产) as well as other’s. The unpunctual person is always complaining that he finds no time to answer letters, or return calls or keep appointments promptly. But the man who really has a great deal to do is very careful of his time and seldom complains of want of it. He knows that he can not get through his huge amount of work unless he faithfully keeps every piece of work when it has to be attended to.
Failure to be punctual in keeping one’s appointments is the sign of disrespect towards others. If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him. Usually this will be regarded as a great disrespect to the host and all other guests present.
Unpunctuality, moreover, is very harmful when it comes to do one’s duty, whether public or private. Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time. A man who is known to be habitually unpunctual is never trusted by his friends or fellow men.

1.
What does the author think is the main difference between a punctual person and an unpunctual person?
1. A.
  A punctual person does everything ahead of time while an unpunctual person does everything behind schedule.
2. B.
  A punctual person does everything at the right time while an unpunctual person seldom does anything at the correct time.
3. C.
  A punctual person has a lot of appointments while an unpunctual person has few appointments.
4. D.
  A punctual person has much time to do everything while an unpunctual person has little time to do anything.
2.
According to the passage, the main reason that a person is always unpunctual is that _______.
1. A.
  he has more work to do than other people
2. B.
  he is always in a hurry when he works
3. C.
  he doesn’t care much about time
4. D.
  he always mismanages and wastes his time
3.
According to the third paragraph, when you are invited to dinner, you should arrive there _______.
1. A.
  after other guests have arrived
2. B.
  before all other guests
3. C.
  at the appointed time
4. D.
  after the host has got things ready
4.
Which of the following statements best describes the harm of unpunctuality?
1. A.
  If you are an unpunctual person, you cannot be in charge of any important task.
2. B.
  If your friends know that you are unpunctual, they may not see you again.

Flying over a desert in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's flight one of the scientists wrote in his notebook, "Look here for probable metal." Walking across hilly ground, four scientists reported, "This ground should be searched for metals." From an airplane over a hilly wasteland a scientist sent back by radio one word "Uranium".
None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth's surface. They were merely putting to use one of the newest methods of locating minerals in the ground -- using trees and plants as signs that certain minerals may lie under the ground on which the trees and plants are growing.
This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface.
At Watson Bar Creek, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes andtested. Each small part was examined to learn whether there were minerals in it.
Study of the roots, branches and seeds showed no silver. But there were small amount of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches.
If the trees indicated that there was no gold in the ground, the scientists wouldn't spare money to pay for digging into the ground.

1.
Scientists were flying over a desert or a hilly wasteland or a mountain region to ________.
1. A.
  train their eyes
2. B.
  study the trees
3. C.
  look for gold
4. D.
  search for minerals
2.
The study of trees, branches and roots indicated that __________.
1. A.
  there were larger amounts of gold in the branches far from the tree trunk than in the seeds
2. B.
  there were smaller amounts of gold in the tree roots deep in the ground than in the branches
3. C.
  there were larger amounts of gold in the seeds growing closer to the tree trunk than in the seeds farther from it
4. D.
  there were larger amounts of gold in the branches than in the leaves on the ends of the branches
3.
Which of the following is NOT mentioned as part of a tree that can help the searchers?
1. A.
  Leaves.
2. B.
  Roots.
3. C.
  Branches.
4. D.
  Seeds.
4.
Which of the following might be the best title for this passage?
1. A.
  Scientists searching for treasure with special equipment.
2. B.
  New methods of doing geological study.
3. C.
  Gold could be found in trees and plants.

Electricity, like clean water, is a resource that’s often taken for granted. But last summer, when blackouts struck much of the northeastern US, Ontario and Rome, consumers on two continents were given a painful reminder of just how easily broken electricity supplies can be. The massive disorder stranded (使陷入困境)commuters, stopped freezers, shut down businesses and refocused attention on where most of the planet’s power comes from：oil-and-gas-fired generators and nuclear plants, These sources not only pollute the environment but also make many consumers feel unacceptable health risks.
Companies are trying to offer an alternative, clean energy from renewable resources that’s plentiful and portable. Lifton’s Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and dolor panels to give people power whenever and wherever they want it, free from dependence on local grids(电网).
The search for alternative energy is nothing new, but the current trend of innovators is focusing on the goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell, which produces electricity from the chemical reaction between oxygen and hydrogen, has been around for about 150 years, though its commercial development did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fuel free hydrogen economy by 2030.
When hydrogen and oxygen molecules(分子)combine, the reaction produces heat and water. Fuel cells use this reaction to generate electricity. With the cell phone and gadget(小机件)market in mind, Medis has developed a fuel cell with cheap components that produces little heat and effortlessly reduces waste water without turning to energy consuming pumps.

1.
What is the passage mainly about?
1. A.
  The future of alternative energy
2. B.
  How the fuel cells works
3. C.
  People’s search for alternative energy
4. D.
  The damage done by the blackout last summer.
2.
What can we know about the fuel cell?
1. A.
  Its commercial use began in the 1960s.
2. B.
  Today it’s being used in almost every corner of the world.
3. C.
  It has been in widespread used for about 150 years.
4. D.
  It supplies electricity to make the combination of oxygen and hydrogen possible.
3.
Which of the following statements is NOT true according to the passage?
1. A.
  Lifton’s Medis Technologies is tapping into fuel cells and solar panels.
2. B.
  The fuel cell has been around for about 150 years.
3. C.
  The fuel cell’s commercial development did not begin until the 1960s.
4. D.
  When hydrogen and oxygen molecules combine, the reaction produces o2 and H2O.
4.
The underlined word “blackouts” in the 1 st paragraph means_____.
1. A.
  power failure
2. B.
  the delivering of electricity
3. C.
  the power of electricity
4. D.

After a fortnight of extraordinary type, the much-feared computer virus that was supposed to strike the globe’s hard drives last Friday simply fizzled. So many warnings were sounded that most computer owners either fed anti-virus programs into their systems or refused to turn the power on during the dreaded M-day. They dodged one disease, but more strains are on the way. The eponymous Friday-the-13th virus is due to strike this week, and the Maltese Amoeba may detonate on March 15.
Who creates these things? A disproportionate number seems to originate in Bulgaria or Russia, where writing the smallest, most elegant virus programs has become a matter of quirky pride. Viruses are transmitted either by shared disks (as was Michelangelo) or over telephone lines. The virus program hides in a computer until, activated by a date, time, or some other trigger, it springs to life. The most common virus, Stoned, makes your screen announce: “Your computer is now stoned. Legalize marijuana. ” (Regardless of your politics, you don’t want this one around; it can damage your files inadvertently.) Solution: either keep your computer isolated—no trading disks, no on-line communication—or else install one of a dozen or so commercially available anti-virus programs that detect and delete the little time bombs. If they can come up with a virus that is hidden, will they next try to extort a business?—as in, pay me $1 million or my virus will destroy your system.
In the meantime, money is being made by firms selling anti-virus programs. Egghead software stores logged a 3,000 percent jump in anti-virus sales. Was the threat overblown by the companies that make millions selling anti-virus software? Thanks to the media blitz, no one will ever know what might have happened—an unallied number of computer owners discovered and deleted Michelangelo before it was supposed to strike—on the artist’s birthday.

1.
The much-feared M-day was ________.
1. A.
  Friday-the-13th when the eponymous virus was due to strike
2. B.
  Friday-the-15th when the Maltese Amoeba would be activated
3. C.
  the previous Friday when Michelangelo virus was due to strike
4. D.
  the previous Friday which coincided with the artist's birthday
2.
Computer viruses are ________.
1. A.
  diseases spread from one computer to another by shared disks
2. B.
  viruses hidden in a computer’s instructions by the designers
3. C.
  little time bombs hidden in a computer waiting to be triggered
4. D.
  just those computer programs created by malevolent designers
3.
Which of the following sayings fits the Michelangelo virus?
1. A.
  A burnt child dreads the fire.
2. B.
  The bug’s bark was worse than its bite.
3. C.
  A barking dog seldom bites.
4. D.
  Once bitten, twice shy.
4.
The author implies that in days to come the viruses might be used ________.
1. A.
  to destroy data
2. B.
  to commit crimes
3. C.
  to commit mischief
4. D.

The textbook now has to be revised. New dating techniques suggest the remains of Peking Man--- found in the 1920s---are over 200,000 years older than previously thought. What’s important about that date, about 770,000 ago, is that this was an ice age on Earth.
Over Earth’s long history, there have been a number of times when ice and snow covered a large part of its surface. Such periods are known as ice ages.
Earth is in an ice age now. It started about 2 million years ago. Despite the many warm periods since then, scientists regard the whole time as one ice age because of the continuous existence of at least one large ice sheet---the one over Antarctica.
The new discovery was made by Chinese and US scientists. It suggests Peking Man is probably our oldest cold weather human being, said Darryl Granger, an atmospheric scientist at Purdue University whose research appears in Thursday’s edition of the journal Nature.
The average yearly temperature at the time in that part of China was around the freezing mark, but it was too dry for an ice sheet, Granger said.
This raises a question. How did Peking Man survive the cold weather?
Rick Potts, a Smithsonian Institution human origins expert who wasn’t involved in the research, raised three possibilities:
First, fire. Early findings showed signs of a fire in Peking Man’s cave. But there has been debate about whether the fire was accidental or controlled.
Second, fur. There is no evidence that Peking Man used simple tools to make more form-fitting clothes, it’s more likely he wore animal fur.
Lastly, he may have developed gradually to handle the cold. Peking Man may have experienced physiological changes that allowed more blood to flow to his hands and legs, Potts said. “People in general who live in colder climates tend to be shorter and wider,” he explained.
Unlike the times of Peking Man today the global temperature is rising due to the greenhouse effect. In the future, could humans develop to handle the warmth just as Peking Man did to fight the cold?

1.
According to the new research, Peking Man actually dates back to _______.
1. A.
  around 500,000 years ago
2. B.
  over 200,000 years
3. C.
  about 770,000 years ago
4. D.
  about 2 million years ago
2.
What is the most important standard for scientists to decide an ice age?
1. A.
  The weather conditions.
2. B.
  The continuous existence of any large ice sheets.
3. C.
  The average yearly temperature
4. D.
  The long period of snowfall
3.
Which of the following is true of Peking Man?
1. A.
  He is the oldest human being
2. B.
  He used fire to keep warm
3. C.
  He wore form-fitting clothes made from fur with simple tools.
4. D.
  He might have been shorter and wider than previously thought.
4.
The following are all the possibilities EXCEPT _______ that the Peking Man survived the cold weather.
1. A.
  putting up tents to keep the cold out
2. B.
  wearing animal fur
3. C.
  using fire in their cave
4. D.
  developing gradually to handle the cold.

For years I wanted a flower garden. I’d spend hours thinking of different things I could plant that would look nice together.
But then we had Matthew. And Marvin. And the twins, Alisa and Alan. And then Helen. Five children. I was too busy raising them to grow a garden.
Money was tight, as well as time. Often when my children were little, one of them would want something that cost too much, and I'd have to say, "Do you see a money tree outside? Money doesn't grow on trees, you know."
Finally, all five got through high school and college and were off on their own. I started thinking again about having a garden.
I wasn't sure, though. I mean, gardens do cost money, and after all these years I was used to living on a pretty lean, no-frills budget.
Then, one spring morning, on Mother's Day, I was working in my kitchen. Suddenly, I realized that cars were tooting their horns as they drove by. I looked out the window and there was a new tree, planted right in my yard. I thought it must be a weeping willow, because I saw things blowing around on all its branches. Then I put my glasses on - and I couldn't believe what I saw. There was a money tree in my yard!
I went outside to look. It was true! There were dollar bills, one hundred of them, taped all over that tree. Think of all the garden flowers I could buy with one hundred dollars! There was also a note attached: "IOU eight hours of digging time. Love, Marvin."
Marvin kept his promise, too. He dug up a nice ten-by-fifteen foot bed for me. And my other children bought me tools, ornaments, a trellis (棚架), a sunflower stepping stone and gardening books.
That was three years ago. My garden's now very pretty, just like I wanted. When I go out and weed or tend my flowers, I don't seem to miss my children as much as I once did. It feels like they're right there with me.
I live up in Michigan's Upper Peninsula, where winters are long and cold, and summers are too short. But every year now, when winter sets in, I look out my window and think of the flowers I'll see next spring in my little garden. I think about what my children did for me, and I get tears in my eyes - every time.
I'm still not sure that money grows on trees. But I know love does!

1.
By saying “Do you see a money tree outside .….,” the mother actually means “ ”
1. A.
  Observation is the best teacher.
2. B.
  Seeing is believing.
3. C.
  The outsider sees the most of the game.
4. D.
  It is not easy to gain money
2.
The best title for the passage would probably be .
1. A.
  My flower garden
2. B.
  Marvin helps to realize my dream

But I had already come to my lonely decision. To wake up in the morning with a sense of fear， to force a hasty breakfast down an unwilling throat and then to set off for work with pounding heart and frozen face had become habitual， and I had turned to tranquilizers(镇定剂) to help me along.
It hadn't always been as bad as this. Ten years before I had managed quite well.
I， in common with most other teachers， am rather selfcritical， and I knew now I was no longer “managing”.My classes were noisy， the children were not learning very much， and my attempts to cope with changing teaching methods produced very little effect. At one time my very presence in the doorway would be enough to ensure a partial silence. Now they give a vague(含糊的) “Hello， Miss”， and carry on. I had run out of enjoyment and enthusiasm. It was time to stop.
Was it all my own failure？ In fairness to myself， I don't think it was. I had plenty of ideas， I loved my subject， and I liked children.
I had been idealistic. But the reality I faced was bored children， overstimulated(刺激)by videowatching the night before and tired out by a late bedtime. They were given the wrong food at the wrong time， who came without breakfast to school and then stuffed themselves with gum and chocolates bought on the way； who were “high” with hunger in class and talked restlessly as the cooking smell from the school kitchen came drifting (漂) to all floors.
I had been trying to create the basic conditions in which teaching becomes possible， but I had failed， and no longer had the stomach for the job.

1.
The reason why the writer decided to give up her job was probably that .
1. A.
  teaching children wasn't challenging
2. B.
  she took no pride in her work
3. C.
  teaching had become too much for her
4. D.
  she disliked the new teaching method
2.
“My very presence in the doorway would be enough to ensure a partial silence” means“ ”.
1. A.
  I'd very well make some students stop talking simply by standing in the doorway
2. B.
  when I came to the doorway， the class would immediately quiet down
3. C.
  all the students would become silent on my turning up in the doorway
4. D.
  my appearance in the doorway could at least comfort the class
3.
The following are all reasons that children couldn't concentrate in class EXCEPT .
1. A.
  they were tired out because they went to bed too late
2. B.
  they were burdened with too much homework
3. C.
  they were not properly fed by their parents

Four Insurance Policies You Can' t Do Without
A single gap in insurance coverage could wipe out the money that yon' ve earned for many years through your hard work.That' s why it' s important to give yourself a yearly insurance checkup, whether you buy your policies through an agent or from one of the growing number of insurance companies.
Health.Before selecting a policy from your employer or deciding among Medicare options, review your current health,predictable medical needs, and family status.This review should help you avoid a plan that fails to cover a necessary treatment or paying for services that you know you'll never use.
Disability. Your chances of becoming disabled before you retire are far greater than your chances of dying. So every working person needs some kind of disability coverage. If you are working for an employer who offers less than that, you can buy an individual policy to promote your coverage.
Homeowners or renters. Make sure you have replacement-cost coverage that would pay the current costs of rebuilding your home and replacing your personal possessions. A policy that would only pay for the decrease in value of these items isn' t good enough, because you could end up recovering just a small part of their costs. Don' t forget flood and/or earthquake insurance if you live in a locate that has a possible tendency to these types of disasters.
Life. Empty nesters and retirees may. no longer need life insurance at all. But if you have dependents who would suffer financially if you died, it' s still a must.

1.
To have your insurance checkup every year is mainly because _______.
1. A.
  the gap in insurance coverage could cost you a large sum
2. B.
  the gap in insurance coverage could bring you benefits
3. C.
  some insurance agencies cover few of your policies
4. D.
  too many insurance companies prefer to sell coverage
2.
_______ can be ignored while deciding among Medicare choices.
1. A.
  Your necessary treatment.
2. B.
  Your personal health at present.
3. C.
  Your social status.
4. D.
  Your predictable medical needs.
