Have you ever seen people dance? Some dances are fast and others are slow. People’s feet always move when they dance. They keep on moving until the music stops.
People have enjoyed dancing for a very long time. This story is of a different kind of dance. It is a dance without people or music. Yet this dance is one of the oldest in the world. It is the dance of bees.
If you have ever watched bees, you know that they are very clever. They also work hard looking for food and bringing it back to their home.
The home of the bees is called a bee hive. Here hundreds even thousand of bees live. They work day and night building small walls. There they make their honey. This is the same honey that we eat.
Where does the honey come from? Bees live on food from flowers. Have you seen bees flying around a flower garden? When a bee rests on a flower, it tries to go to the centre of it. There it takes in as much food as its body can hold. Then it flies to take the food back to the hive.
At the hive, bees change flower food into honey. Then they fly away for more food.
How do the bees know where to find the best food in the sweetest flowers? One bee acts as a guide. When it discovers good flowers, it flies back to the hive and tells the others. It does this by dancing for them.
The bee dances on one side. This tells the other bees which way to go to find the flowers. But that is not all. The bee dances for some time. And the length of its dance tells the other bees how far they must fly to reach the flowers.
When the bees see the dance, they know where the flowers are. They fly away and return with more food for the hive.
Sometimes we hear the music of the bees as they fly around. But few people have ever seen them dance. Yet without that dance we might never have sweet honey to eat.

Most Americans enjoy moving from place to place. For example, they often drive their cars 120 to 160 kilometers away just to have dinner with a friend or even fly to Europe just for watching a football match. In some states only one person in five lives in a place for more than five years. One may be born in one city, and go to school in another. He may finish his middle school in two or three cities, and then attend a college far across the country. When he has entered business, he may possibly move from job to job. Moving from one job to another, which is called “job-hopping”, is a very common practice in the United States. Job-hopping is good to workers, because every change of a job gives them a chance to move up to a higher position and to get better pay. And job-hopping also gives bosses the chance to get new ideas and skills that different people bring to their companies and factories.

Introduction
A lot of crime is against bicycles. About 150,000 bicycles are stolen every year and most are never found. You can prevent this happening by following a few careful steps.
Basic Security
Do not leave your bicycle in out-of-the-way places. Always lock your bicycle when you leave. Secure it to lampposts or trees. Take off smaller parts and take them with you, for example lights and saddles（车座）.
Locks
Get a good lock. There are many different types in the shops. Buy one that has been tested against attack. Ask for a recommendation from a bike shop.
Marking
Security marking your bike can act as a deterrent to a thief. It can also help the police find your bicycle. It should be clearly written and include your postcode and your house or flat number. This will provide a simple way to identify your bicycle.
Registration
There are a number of companies who will security mark your bicycle for you. They will then put your registration number and personal details on their computer database. Then if your bicycle is found it will be easy to contact you.

Ⅳ、阅读理解（每小题2分，共30分）
Buster Brown was a thief—and a good one, too, he thought. He’d never been caught by the police because he never took chances. He was always prepared for any unforeseen event or emergency.
Confidently, he stood outside the house of his intended victim（受害者）and read the sign on the front gate of the house. “Don’t worry about the dog—be aware of the owner!” it said. Buster smiled and found his way in.
The house looked quite normal outside, but inside it was very exotic with fascinating objects on display. As he began putting them into his bag, a dog came into the room. It stopped when it saw Buster, then wagged its tail madly and went over to him. Licking his outstretched hand. “Good boy,” Buster whispered. “What a great guard dog you are—trying to lick me to death.”
Satisfied he’d made friends with the dog, Buster began to wander round the house, choosing items to put in his bag. His skilled eye picked out only the best antiques（古董）：a pair of silver candleholders, a silver tea-and-coffee service, etc.. His new friend, the dog, sat and watched, as if wondering what was happening.
“Well, boy,” Buster whispered finally. “That might do. Any more and I won’t be able to carry it!” He swung the heavy bag onto his shoulders, just as the lights came on, nearly blinding him. He shielded his eyes with his hand.
“You’re a very silly person,” the figure in the doorway said, his voice dry as dust. As the man came closer, Buster could see he was well dressed. His face seemed familiar, but Buster couldn’t quite place where he had seen him before.
“You should have taken more notice of the sign outside,” the man resped. “I knew about this attempted robbery last week and I also know you will end up behind bars for 20 years. Fancy trying to rob the house of the world’s greatest fortune-teller!”

D.The house had no security alarm.
2.How did Buster decide which objects to take?
A.He took those that were easy to carry in his bag.
B.He took only the best antiques.
C.He took those that he knew he could sell easily.

They travel in groups, noses just inches away form GPS screen. Suddenly a boy shouts “I found it!”, grinning and walking away from the group.
The others focus on their screens. “Me. too!” shouts another a moment later, until all six kids are crowded around a tree, pulling out a plastic bottle painted to look like tree bark. It doesn’t seem like much from the outside, but everyone gathers around, eager to see what’s inside.
This is geocaching, a high-tech game played using coordinates (坐标) and global positioning systems to find hidden “treasures”.
It’s open to anyone—hiders or seekers—with a GPS and access to www.geocaching.com, where more than half a million users download and upload the coordinates of nearly 1 million hidden caches (储藏物) and write about their experiences in this worldwide hunt.
Although some adventures can take hours or even days, the contents inside the actual cache usually aren’t valuable—often just a book or a small trinket (小饰品).
But participants aren’t in it for the treasure. They say it’s a great way to exercise. Or it brings them to remote destinations or historical sites. Some consider it an extreme sport, looking for geocaches hidden in mountains or in other nearly inaccessible locations.
Jeffrey Howe, 41, sees it as an opportunity to take kids on adventures to unfamiliar places. The youths at the shelter mostly come form the city, but geocaching has taken them to parks, the suburbs, and, once, to a 498-meter-high mountain.
“Geocaching is a way to give kids the idea that there’s a whole world out there other than what they know from their home neighborhoods and video games,” he said.
How does it work? Log onto the Website and enter your zip code (邮编), then search for caches near your location. Although posted coordinates will take a GPS within about 4.5 meters of a cache, a good hide will require seekers to do a bit of hunting around. Caches can’t be buried underground, nor can they be hidden on private property (财产), in dangerous locations or in some national parks.
Posts written about the find—whether successful or unsuccessful—are an important part of the game, with users proudly recording the places to which they’ve traveled.
