Bears and humans often meet in National Parks. Although campers and hikers are warned not to feed the bears, many people ignore these warnings and feed the beasts anyway. When bears are used to people’s food, problems soon arise.
Bears like to eat a large variety of things, both meat and vegetable. Without human assistance, bears live nicely on roots, twigs, leaves of trees, insects and small animals. With people around, the bears’ tastes quickly expand to include sandwiches, hot dogs, hamburgers, and anything else they can temp humans into giving up.
Bears often develop clever strategies for getting people to let go their food supplies. More often than not, an unsuspecting hiker has taken off his or her pack for a rest only to have a bear charge out of the woods, grab the pack and quickly disappear into the underbrush with it. Hanging the pack on a tree branch won’t help. Bears have been known to climb up, jump off, and catch the pack on the way down. One mother bear stretched up with her baby on her shoulders to reach a pack stored on a pole. Many bears threaten people into giving up their supplies. Although a bear is unlikely to attack a person and would probably run away if screamed at, few people are willing to do so. Most people drop the pack and run the other way. This, of course, delights the bear. In some places, the Park Service installed some metal barrels with lids to help campers keep their supplies safe from bears. Although the bears were unable to open these containers, the effort was less than successful. Most campers, unable to tell the metal drums from rubbish cans, never used them for the intended purpose.

Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.

European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.

What seems like science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004.

A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex.

"It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia.

Just like bears and frogs, the hibernation of human beings would cause a person's metabolism (新陈代谢) to lower so they would need less energy.

Medical research, however, is just half of a space flight hibernation system.

There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.

According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon (木星的卫星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.

9. European researchers are conducting hibernation experiments to ________.

A. ensure astronauts to get a complete sleep  B. find the secret of some creatures

C. make preparations for the journey to Jupiter’s moon Callisto

D. know if man can sleep for years

 10. The sentence “What seems like science fiction is not completely unlikely” means ______.

A. Science fiction is people’s imagination.

B. Science fiction is imaginative, but it can be realized.

C. Things seem impossible may come true.

D. Things described in science fiction are sure to become true.

11. The passage is implied but doesn’t states that ________.

A. putting living cells into a sleep-like state is full of failure

B. Biggiogera is confident with the experiment

C. human’s hibernation needs no energy

D. medical research is the key to space flight hibernation system

12. By designing a suitable protective shelter, astronauts can ________.

A. have a good hibernation        B. lessen the pressure of traveling in space

C. feed themselves in spaceship    D. moinitor their body changes

13. What’s the best title for the passage?

A. Six humans to fly to Callisto  B. Human hibernation improves health

C. Space travel attracts people   D. Deep sleep for deep space travel

Could a grizzly bear move to your neighborhood? If you live in the U.S. West, the answer may be yes. People and grizzly bears are living closer together now.
The grizzly bear is one of the largest meat-eating land animals in North America. In the early 1800s, about 50,000 grizzly bears lived there. Today there’re far fewer bears. Settlers built cities and roads where bears lived. Many bears were hunted and killed. Now only 1,200 to 1,400 grizzly bears have remained.
In and around Yellowstone National Park, grizzly bears have been making a comeback because of people’s efforts to protect them. Some bears are moving to areas where people live. People are also moving into grizzly countries.
People there have to learn how to live with their new, furry (毛皮的) neighbors peacefully. If someone leaves their barbecue grill（烤肉架）out overnight, or leaves their pet food or rubbish where a bear can get it, the bear will learn to come to their house for food. Grizzly bears that learn to eat people’s food can become dangerous, and they often have to be killed or moved. Also, it’s important not to surprise a grizzly. Besides, if you are hiking in a grizzly country, you should go with others and make a noise to make bears hear your coming and get out of the way. You may not want to invite grizzly bears to your next neighborhood party, but with a little effort, grizzly bears and people can live together peacefully.
【小题1】Why does the number of grizzly bears get smaller, according to the text?

A．Settlers’ buildings break the balance of their living environment.
B．Land for them to live on is limited and they are hunted in large numbers.
C．Yellowstone National Park wants to control the number of them.
D．Living closer to humans makes them die from serious diseases.
【小题2】 How many suggestions are made for people to live with bears peacefully？
A．One. B．Two. C．Three.D．Four.
【小题3】 Compared with the early 1800s, the number of grizzly bears has got smaller by ______.
A．exactly 26﹪B．over 36﹪C．nearly 64﹪D．about 96﹪
【小题4】 Which of the following statements is TRUE according to the passage?

D．How to live with grizzly bears peacefully.

On a number of drives throughout my childhood, my mother would suddenly pull over the car to examine a flower by the side of the road or rescue a beetle from tragedy while I, in my late teens and early twenties, sat impatiently in the car.

Though Mother’s Day follows Earth Day, for me, they have always been related to each other. My mom has been “green” since she became concerned about the environment. Part of this habit was born of thrift (节俭). Like her mother and her grandmother before her, mom saves glass jars, empty cheese containers and reuses her plastic bags.

Mom creates a kind of harmonious relationship with wildlife in her yard. She knows to pick the apples on her trees a little early to avoid the bears and that if she leaves the bird feeders(给食器) out at night, it is likely that they will be knocked down by a family of raccoons (浣熊). Spiders that make their way into the house and are caught in juice glasses will be set loose in the garden.

I try to teach my children that looking out for the environment starts with being aware of the environment. On busy streets, we look for dandelions (蒲公英) to fly in the wind; we say hello to neighborhood cats and pick up plastic cups and paper bags. This teaching comes easily, I realize, because I was taught so well by example. Mom didn’t need to lecture; she didn’t need to beat a drum to change the world. She simply slowed down enough to enjoy living in it and with that joy came mercy and an instinct for protection.

I am slowing down and it isn’t because of the weight of my nearly forty years on the planet, it is out of my concern for the planet itself. I’ve begun to save glass jars and reuse packing envelopes. I pause in my daily tasks to watch the squirrels race each other in the trees above my house.

Last summer, in the company of my son and daughter, I planted tomatoes in my yard. With the heat of August around me, I ate the first while sitting on my low wall with dirt on my hands. Warm from the sun, it burst on my tongue with a sweetness I immediately wanted to share with my mom.

By the year 1869 when the first transcontinental railroad was finished, over 350,000 pioneers had taken the Oregon Trail to head west and start a new life, which is known as the Gold Rush Period in American history. Many of these were women and most were accompanied by children.

Before heading west, many women often spent their day doing nothing more than visiting, needlework, and the occasional gardening of flowers. Others were not from as wealthy families and had to work alongside their men as laborers. Neither type was in most cases prepared for the hardships that lay ahead.

Once they did reach their destination, the work was far from over. A house would need to be built. Women quickly learned to use all kinds of tools right alongside their husbands. At the first sign of spring, a garden would need to be planted. Pioneer women also had to deal with dangerous wild animals, including bears and lions. Indians were also a concern, and some did fall to their deaths by the Indians’ hand. Where were the men when all this was being done? Working the fields and mining were the two most usual occupations. Their remaining work, which there was plenty of, fell to the women and the oldest children if there were any.

Women who headed west learned quickly that there was much more to life than teas and visiting. They had no choice but to struggle for survival. This was their life.
