remember their dreams. As soon as they wake up, they record what their dreams were about.
Scientists believe that we have different kinds of sleep. One kind is called R.E.M. R.E.M. stands
for rapid eye movement. During this kind of sleep our eyes move quickly, even though they are closed.
Although we are asleep, there are a lot of brain activities. We probably have dreams at this time.
Sometimes people talk in their sleep. In these dreams the dreamer is usually unhappy or worried
about something. The worst of the dreams are so frightening that we call them nightmares. In a nightmare
we often dream that we are being closed or that we are trapped in some way.
Scientists or others have written books about the meanings of dreams. The most famous of these
scientists was Sigmund Freud who wrote a hundred years ago. He suggested different meanings to
certain kinds of dreams. It is possible, however, that every dream has a special meaning only for the
person who dreams it, and that this dream about something is in that person"s life.
B. They are worried about something.
C. Their eyes are moving quickly.
D. Their eyes are moving slowly.
B. The meaning of dreams.
C. People and their dreams.
D. R.E.M. and sleep and dreams.
Let us suppose it is now about A.D. 2060. Let"s make believe(假设;虚构) it is about sixty years from now. Of course, things have changed and life is very different.
Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many
hotels have been built. The hotels are air-conditioned, naturally. In order that everyone can enjoy the
beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is
provided for entertainment(娱乐) of young and old.
What are people eating now? People are still eating food. They haven"t yet started to take on heir(继承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods
now come in pill form, and the food that goes into the pill continues to come mainly from green plants.
Since there are several times as many people in the world today as there were a hundred years ago,
most of our planet"s surface has to be filled. The deserts are irrigated with water and crops are no longer
destroyed by pests. The harvest is always good.
Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible
to run the farm by just pushing a few buttons now and then.
People are now largely vegetarians(素食者). You see, as the number of people increases, the number
of animals decreases. Therefore, the people have to be vegetarians and we are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of
diseases. No one has to be ill any more.
Such would be our life in 2060.
B. Many other animals.
C. Many plants.
D. A sea.
B. Foods in pill form.
C. Foods in water form.
D. Foods in gas form.
B. there are more pests
C. there is less water
D. the crops are getting better
B. Because doctors advise them not to eat meat.
C. Because the number of animals decreases.
D. Because all the animals have died of d iseases.
Stingrays are pancake-shaped fish, and you"d never guess it: they"re close cousins of sharks.The
smallest kinds are about the size of a dinner plate. But some 4-metre stingrays live in the waters near
Australia. About 170 different kinds of stingrays live in the oceans around the world. And some live
in freshwater too. In South America, a few kinds swim in the Amazon and other rivers that flow into
the Atlantic. One ocean kind, the Atlantic stingray, also
lives in the St. Johns River in Florida.
A stingray has a mouth and nostrils(鼻孔) on the bottom of its body. These nostrils are for smelling,
not for breathing. When water flows into a stingray"s nostrils, the fish may pick up the smells of creatures
it wants to eat. It can also find prey (牺牲者) by sensing the tiny amount of electricity that animals give
off. Slowly, slowly the fish hunts by moving along the ocean or river bottom. When it senses a worm,
clam, shrimp, or other creature, it flaps (拍打) its fins until the prey is uncovered. Then the fish lies down
over the prey, sucks it in, and crunches it with its small teeth. A stingray"s flat shape helps it hide. It stirs
up a cloud of sand by flapping its big, flat fins. When the sand settles down over the fish, everything is
covered but its eyes, breathing holes, and sometimes its tail. Its tail gave the "sting" to a stingray"s name.
When a stingray is attacked by an enemy, it whips its tail around. Then a sharp stinger releases a powerful poison into the enemy. When stingrays are on the ocean bottom, it"s easy for a diver to step on one by
mistake. Then the fish usually stings the person in the ankle. The poison is very painful, and the wound
may hurt for a day or two. Worse yet, pieces of the stinger can break off and infect the ankle. But
stingrays don"t chase after prey or people to sting them. In fact, divers can swim among friendly stingrays
without getting hurt.
B. To give readers facts about an interesting fish.
C. To warn readers about dangers in the ocean.
D. To teach readers how fish hunt their prey
B. can cover themselves with sand
C. move slowly above the ocean floor
D. live in freshwater as well as in oceans
B. To escape from the prey.
C. To find the prey.
D. To frighten the prey.
B. Pieces of the stinger come loose in the wound.
C. Electricity from the stinger shocks the wound.
D. Fins beside the stinger throw sand into the wound.
Everyone is getting unwell."
This may sound like something someone would say today. But in fact, an unknown citizen who
lived in Rome in 53 AD wrote it.
We all love new inventions. They are exciting, amazing and can even change our lives. But have
all these developments really improve the quality of our lives?
Picture this, you"re rushing to finish your homework on the computer. Your mobile phone rings,
a QQ message from your friend appears on the screen, and the noise from the television is getting
louder and louder. Suddenly the computer goes blank and you lose all your work. Now you have
to stay up all night to get it done. How calm and happy do you feel?
Inventions have speeded up our lives so much that they often leave us feeling stressed and tired.
Why do you think people who live far away from noisy cities, who have no telephones, no cars,
even no electricity often seem to be happier? Perhaps because they lead simpler lives.
One family in the UK went "back in time" to see what life was like without all the inventions we
have today. The grandparents, with their daughter, and grandsons Benjamin, 10, and Thomas, 7,
spent nine weeks in a 1940s house. They had no washing machine, microwave, computer or mobile
phones.
The grandmother, Lynn said, "It was hard physically, but not mentally." She believed life was less
materialistic. "The more things you have the more difficult life becomes." She said. The boys said they
found less to fight over, such as their computer. Benjamin also noticed that his grandmother had
changed from being a "trendy, beer- drinking granny to one who cooked things".
Here are some simple ways to beat the stress often caused by our inventions!
●Don"t be available all the time.Turn off your mobile phone at certain times of the day.Don"t
check your emails every day.
●Make sure you spend some time talking to your family.Set aside one evening a week when you
don"t turn on the television.Play cards and chat instead.
●Get a low-tech hobby.Every day,do something in the old-fashioned way,such as walking to have
a face-to-face meeting instead of using the email or telephone.
●Don"t worry too much about life-laugh more!

Two hours from the tall buildings of Manhattan and Philadelphia live some of the world’s largest black bears. They are in northern Pennsylvania’s Pocono Mountains, a home they share with an abundance of other wildlife.
The streams, lakes, meadows (草地), mountain ridges and forests that make the Poconos an ideal place for black bears have also attracted more people to the region. Open spaces are threatened by plans for housing estates and important habitats are endangered by highway construction. To protect the Poconos natural beauty from irresponsible development, the Nature Conservancy (大自然保护协会) named the area one of America’s “Last Great Places”.
Operating out of a century-old schoolhouse in the village of Long Pond, Pennsylvania, the conservancy’s bud Cook is working with local people and business leaders to balance economic growth with environmental protection. By developing partnerships with people like Francis Altemose, the Conservancy has been able to protect more than 14,000 acres of environmentally important land in the area.
Altemose’s family has farmed in the Pocono area for generations. Two years ago Francis worked with the Conservancy to include his farm in a county farmland protection program. As a result, his family’s land can be protected from development and the Altemoses will be better able to provide a secure financial future for their 7-year-old grandson.
Cook owes the Conservancy’s success in the Poconos to having a local presence and a commitment to working with local residents.
"The key to protecting these remarkable lands is connecting with the local community,"Cook said. “The people who live there respect the land. They value quiet forests, clear streams and abundant wildlife. They are eager to help with conservation effort.

fall and winter, and she saw the light literally. Every morning now she turns on a specially constructed light box for half an hour and sits in front of it to trick her brain into thinking it’s still enjoying those long summer days. It seems to work.
Krentz is not alone. Scientists estimate that 10 million Americans suffer from seasonal depression and
25 million more develop milder versions. But there’s never been definitive proof that treatment with very
bright lights makes a difference. After all, it’s hard to do a double-blind test when the subjects can see for
themselves whether or not the light is on. That’s why nobody has ever separated the real effects of light
therapy from placebo(安慰剂) effects.
Until now, in three separate studies published last month, researchers report not only that light therapy works better than a placebo but that treatment is usually more effective in the early morning than in the
evening. In two of the groups, the placebo problem was resolved by telling patients they were comparing
light boxes to a new anti-depressant device that gives off negatively charged ions(离子). The third used the timing of light therapy as the control.
Why does light therapy work? No one really knows. “Our research suggests it has something to do
with shifting the body’s internal clock,” says psychiatrist Dr. Lewey. The body is programmed to start the day with sunrise, he explains, and this gets later as the days get shorter. But why such subtle shifts make
some people depressed and not others is a mystery.
That hasn’t stopped thousands of winter depressives from trying to heal themselves. Light boxes for
that purpose are available without a doctor’s prescription. That bothers psychologist Michael Terman of
Columbia University. He is worried that the boxes may be tried by patients who suffer from mental illness
that can’t be treated with light. Terman has developed a questionnaire to help determine whether expert
care is needed.
In any event, you should choose a reputable manufacturer. Whatever product you use should give off
only visible light, because ultraviolet light damages the eyes. If you are photosensitive(对光敏感的), you
may develop a rash. Otherwise, the main drawback is having to sit in front of the light for 30 to 60 minutes in the morning. That’s an inconvenience many winter depressives can live with.
1. What is the probable cause of Krentz’s problem?
A. An unexpected gain in body weight.
B. Unexplained impairment of her nervous system.
C. Weakening of her eyesight with the setting in of winter.
D. Poor adjustment of her body clock to seasonal changes.
2. What is the CURRENT view concerning the treatment of seasonal depression with bright lights?
A. Its effect remains to be seen.
B. It serves as a kind of placebo.
C. It proves to be an effective therapy.
D. It hardly produces any effects.
3. What is psychologist Michael Terman’s major concern?
A. Winter depressives will be addicted to using light boxes.
B. No mental patients would bother to consult psychiatrists.
C. Bad light boxes will give off harmful ultraviolet lights.
D. Light therapy could be misused by certain mental patients.
4. Which of the following statements is TRUE?
A. Winter depressives prefer light therapy in spite of its inconvenience.
B. Light therapy increases the patient’s photosensitivity.
C. Eye damage is a side effect of light therapy.
D. Light boxes can be programmed to correspond to shifts in the body clock.
