Of all the components of a good night’s sleep, dreams seem to be last within our control. In dreams, a window opens into a world where there is zero logic and dead people can speak. A century ago, Freud formulated(创立理论) his revolutionary theory that dreams were the hidden shadows of our unconscious desires and fears; by the late 1970s, neurologists(神经病学家) had switched to thinking of them as just “mental noise”—the random byproducts(副产品) of the neural repair work that goes on during sleep. Now researchers suspect that dreams are regulating moods while the brain is “offline”. And one leading authority says that these intensely powerful mental events actually can be bought under conscious control, to help us sleep and feel better. “It’s your dream,” says Rosalind Cartwright, chair of psychology at Chicago’s Medical Center. “If you don’t like it, change it.”
Evidence from brain imaging supports this view. The brain is as active during rapid eye movement sleep when most vivid dreams occur as it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved: the limbic system or the emotional brain is especially active, while the prefrontal cortex—the center of intellect and reasoning, is relatively quiet. “We wake up from dreams happy or depressed, and those feelings can stay with us all day,” says Stanford sleep researcher Dr. William Dement. This link is shown among the patients in Cartwright’s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don’t always think about the emotional significance of the day’s events—until, it appears, we begin to dream.
There is probably little reason to pay attention to our dreams at all unless they keep us from sleeping or “We wake up in a panic,” Cartwright says. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep or rather dream on it and you’ll feel better in the morning.What does Rosalind Cartwright think of dreams?

Last night’s meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothsclild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.
“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”
Astronomers---scientists who study stars and planets----have been complaining about this problem for decades.They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.
There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds,bats frogs,snakes,etc. For example,outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”
Countless more animals casualties(伤亡）result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings,but some scientists think it can be harmful for humans,too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer.
Emerald Valley is only one community that is becoming aware of the negative effects of hight pollution. For years, Flagstaff,Arizona, has enforced lighting regulations in its city in order to help astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.It happened last night that __________ .
| A．the city light show attracted many people |
| B．the meteors flew past before being noticed |
| C．the city’s lights affected the meteor watching |
| D．the meteor watching ended up a social outing |
What do the astronomers complain about?
| A．Light pollution has remained unsolved for years |
| B．Their observation equipment is in poor repair |
| C．Meteor showers occur less often than before |
| D．Their eyesight is failing due to artificial lighting |
What the author concerned about according to Paragraph 4?
| A．Birds may take other migration paths |
| B．Animal’living habits may change suddenly |
| C．Varieties of animals will become sharply reduced |
| D．Animals’survival is threatened by outdoor lighting |
Lighting regulations in Flagstaff,Arizona are put into effect to__________.
| A．Lessen the chance of getting cancer |
| B．ensure citizens a good sleep at night |
| C．create an ideal observation condition |
| D．enable all creatures to live in harmony |
What message does the author most want to give us?
| A．Saving wildlife is saving ourselves |
| B．Human activities should be environmentally friendly |
| C．Great efforts should be made to save energy |
| D．New equipment should be introduced for space study |
The deserts of the world are not all covered with sand. Many of them have surfaces of rock or clay or small stones. They are not flat, either. They often have high hills and deep valleys. There is some plants’ life in many parts of the desert. There is little rain in the desert, but it does fall often enough for most plants.
The deserts of the world are not uninhabited(not lived by people). People also live outside oases(绿洲), but these people are not farmers. They have camels, goats, donkeys, sheep, etc. These animals can live on the desert plants and do not need much water.
The people of the desert have to move constantly from place to place, they must always look for grass or desert plants for their animals. They usually live in tents. When there is no more food for their animals, they fold up their tents, pat them on their camels and donkeys, and move to another place. In good years, when there is enough food for their animals, they trade their skins and their goats and camel hairs with the people of oases for wheat and fruit. But in bad years, when there is not enough food for their animals, the people of the desert would attack the oases people. But they are also hospitable, no man in the desert would ever refuse to give a stranger food and water.According to the passage, deserts are mostly made up of _______.
| A．clay | B．rock |

People live _______.
| A．only inside the oases |
| B．only outside the oases |
| C．both inside and outside the oases |

Travel is fun and exciting, but it’s not if you get sick. You may think, “Not me, I won’t get sick in my holiday.” But, for many people, that is what happens.
Of course you don’t want to spend your holiday sick in bed. So what can you do to stay in good health? There are three things you should remember when you travel: relax, sleep, and eat well.
A holiday must be a time for relaxing. But very often it is not. Think about what you do when you are a traveller. There are many places to visit: museums, shops, parks, churches. You may spend most days walking around these places. This can be very tiring. You may have a terrible headache after a few hours. If this is the way you feel, you should take a rest. Don’t ask your body to do too much. A tired body means a weak body. And a weak body gets sick easily. So sit down for a few hours in a nice place. In good weather, look for a quiet park bench(石凳). Or you can stop at a cafe. You can learn a lot by watching people while you rest.
Sleep is also important. If you want to stay healthy, you need to get enough sleep. You may have trouble sleeping at night when you travel. There may be too many noises in your hotel or the bed may be uncomfortable. If this is true, don’t be afraid to change rooms or hotels. Or you may get enough sleep for another reason. You may want to stay out late at night. In many cities, the nightlife can be very exciting. Then you should plan to sleep for an hour during the day. The extra(额外) hour can make a big difference。
Finally, if you want to stay healthy, you must eat the right kinds of foods but you need to be careful about how much you eat. Lots of food is not good for you.
So, remember this, if you want to enjoy your holiday, take care of yourself. Give your body some rest. Get enough sleep and eat good, healthy food.This passage is about ______

In the north of Scotland there is a lake called Loch Ness. It is the biggest lake in Britain. It is over thirty kilometres long and in places nearly 300 meters deep. It is cold and dark and not many people went there until after 1930. Then a road was made around the lake. Holiday makers began to use the road, and this was when the stories began.
Someone said that he had seen a monster in the lake. He said it was twelve meters long. It had a long neck and a small head. Then someone else said he had seen it. Others said the same thing and in 1933 a London doctor took a photo. It looked like a monster with a long neck and a thick body but the photo was not dear. The newspapers printed the picture and called it the Loch Ness monster, or "Nessie".
Then the argument began. Some people, however, were certain there was something living in the lake. Others said there was nothing there.
In 1961, a lot of people joined together to make a real effort to see and photograph the monster if there was one! Several times people thought they saw something but after ten years there was still no real proof.
Later underwater television cameras were used, but no one found any real proof. However, they did find something interesting: a huge underwater cave. It was big enough to be home of a monster, but of course, this was not a proof.
In 1975, however, some American scientists formed a search group. They used an underwater camera. It took pictures every seventy seconds. Some of the pictures seemed to show a red-brown creature. Its body was about four meters long and had a very ugly head on the end of a four meter neck. Many people then began to believe in the monster. But even today we can not be certain.Before 1930, ____.
| A．few people went to Loch Ness Lake |
