We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(迁移) is probably the migration of the fish, which is called the “salmon”. This fish is born in fresh water but it travels many miles to salt water. There it spends most of its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mice that leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed by falling into the sea.
Recently, scientists have studied the migration of a kind of lobsters(龙虾). Every year, when the season of bad weather arrives, lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go.
So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface(BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person’s thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right band. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord （脊髓）to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.BCI is a technology that can ________.
| A．help to update computer systems |
| B．link the human brain with computers |

Mr. Johnson, aged twenty-three, battled for half an hour to escape from his trapped car yesterday when it landed upside down in three feet of water. Mr. Johnson took the only escape route—through the boot (行李箱).
Mr. Johnson’s car had finished up in a ditch (沟渠) at Romney Marsin, Kent after skidding on ice and hitting a bank. “Fortunately, the water began to come in only slowly,” Mr. Johnson said, “I couldn’t force the doors because they were jammed against the walls of the ditch and dared not open the windows because I knew water would come flooding in.”
Mr. Johnson, a sweet salesman of Sitting Home, Kent, first tried to attract the attention of other motorists by sounding the horn and hammering on the roof and boot (汽车行李箱). Then he began his struggle to escape.
Later he said, “It was really a half penny that saved my life. It was the only coin I had in my pocket and I used it to unscrew(拧开…的螺丝) the back seat to get into the boot. I hammered desperately with a hammer trying to make someone hear, but no help came.”
It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the boot. Then Mr. Johnson found a wrench(扳钳) and began to work on the boot lock. Fifteen minutes passed by. “It was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in. I forced the lid down into the mud and scrambled (move with difficulty) as the car filled up.”
His hands and arms were cut and bruised (擦伤). Mr. Johnson got to Beckett Farm nearby, where he was looked after by the farmer’s wife, Mrs. Lucy Bates. Huddled in a blanket, he said, “The thirty minutes seemed like hours.” Only the tips of the car wheels were visible(can be seen), police said last night. The vehicle had sunk into two feet of mud at the bottom of the ditch.What is the best title for this newspaper article?

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein, like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality .Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.According to the passage,_________.
| A．we should always keep fit |

Group–buying in China
Modeled after US hot website Groupon.com, group buying websites are now popular in China. These websites use the power of group buying to get competitive discounts (打折)for a daily deal on some best stuff to do, see, eat and buy in the cities across China. Discounts are available within just one click. Zhao lei, a software engineer in Beijing, loves the one-hour lunch break at noon, as it is the best time for him to check “today’s special” at his favorite group buying websites . Sometimes he searches for great deals at directory sites devoted to the new shopping space. Zhao spends around 800 yuan ($117.65) on group buying every month, mostly to buy food coupons (优惠劵)for eating at some nice restaurants and occasionally to find something fun to do. ‘‘I love group buying. In addition to the competitive discounts it offers, it helps me get something fun, exciting and new, and such surprises give me a reason to try something new,” he said. When he finds a really good bargain, he will send the link to friends or colleagues through MSN,QQ, or e-mail, or share the information at some social networking websites. In doing so, he often gets a certain cut off the price. At some sites, buyers are invited to leave notes about what they want to buy and the website will consider it if similar applications(申请)reach a certain number. That is how Zuo got her digital camera after waiting for two months. “It is cool. I want to buy a new digital camera for my trip to Switzerland this winter, but I never expected such cheap prices!”Zuo said.We can learn from the passage that________.

By the time we finished, herring(鲱鱼)covered the bottom of the boat as deep as my calves(腿肚子). For the first time in days, my father seemed happy as a herring choker(捕鲱鱼的人). Then he looked at the western sky, and his smile faded. The storms were sweeping out of Canada hard and fast. No one could predict their arrival. All fishermen feared them.
“We’re going back,” my father said. He pulled the cord and started the motor.
We were only two miles out, but the shoreline looked to me as far away as the moon. Over the distant hills, black clouds ran toward us like wild horses. We made it only halfway home before we met the storm.
The wind came first. It lifted the lake in whitecaps. The weight of the herring made us ride low in the water, and the waves broke over our bow. My father struggled to hold us on course. I’d put on my raincoat, but I had no life jacket.
Then the rain fell so hard we couldn’t see the land. The boat was filling with water. I was scared, but I saw my father sitting straight, holding the boat steady into the wind, and I felt hopeful. He didn’t look hurt at all.
I was starting to think we were going to make it. That’s when the motor died. My father pulled the cord hard, but the motor wouldn’t catch. We would go down in no time.
“Grab an oar(浆),” he cried above the wind. He always carried two oars for just such a moment. We began to pull hard. My father grunted, from pain or effort I couldn’t tell. He dug his oar into the violent lake and bowed into the wind again. With all my strength, I pulled on my own oar.
The wind pushed hard against us. Ws seemed to be fighting the anger of the whole lake. I was tired. My arms felt heavy and on fire. I didn’t know how much longer I could push that oar through the water.
As if he heard my thinking, my father called to me, “I need you, Karl. Only a little longer.”
So I kept rowing.
Just when I thought I had no more strength, I heard it. The sound of waves breaking against the shore. We moved into the shelter of our small cove and rode the swells toward the landing.
My mother rushed through the rain to greet us. “I’ve been so worried,” she said. She hugged me and then my father.
“Nothing to worry about,” he assured her. He put his hand on my shoulder. “You did well, son. How do you feel?”
