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.

A long time ago, there was a seed and because he was only a seed, nobody noticed him. Thus, feeling inferior (低级的), the seed gave no importance to his existence (存在). Then one day, a wind picked him up and threw him on an open field in the sun. Later, he was given rain. Years later he saw a traveler sitting by his side. "Thank you God for this. I really need some rest," he heard the traveler say. "What are you talking about?" the seed quickly asked. He thought the man was making fun of him. No one ever spoke to him like that. "Who just spoke?" the shocked man asked. "It is me. A seed." "A seed?" The man looked at the big tree. "Are you joking? You are not a seed. You are a big tree!" "Really?" "Yes! Why else do you think people come here?" "What do they come here for?" "To feel your shade (树阴)! Don’t tell me you didn’t know you had grown over time." A moment passed before the traveler’s words brought him pride. The seed thought and smiled for the first time in his life. The years of torture (折磨) by the sun and the rain finally helped him grow up. "Oh! That means I’m not a little seed anymore! I was actually born to make people feel comfortable. Wow! That’s great!"
【小题1】The seed didn’t realize the importance of his existence because __________.

If you are looking for an animal to take the title of “most violent fish in the sea”, then the tiger puffer (河豚) fish would have to be a strong contestant. Not only is it deadly poisonous --- though that doesn’t stop people trying to eat it --- but it is also able to scare off enemies by inflating itself to become much larger than normal, when it is young it even chews on its own brothers and sisters.
Tiger puffer fish attach their eggs to rocks near the bottom of the sea, often at the mouths of bays. Then the larvae (幼鱼) move to the entries of rivers and lakes once they have grown a little. Then, having put on a lot of weight, they head out to sea. There’s no innocent childhood for the puffer fish, as Shin Oikawa of Kyushu University in Japan and his colleagues found out when they put the larvae of tiger puffer fish in the lab and monitored them for two months. They found that the larvae went through three steps in which their metabolic(新陈代谢) rates increased dramatically when they reached body weights of 0.002g, 0.01g, and 0.1g. When a larva went through one of these steps, its behavior also changed. For instance, once a larva had passed the first level it would have grown its first tooth and could start attacking larvae that had not yet reached that stage. Similarly, any larva that had reached the 0.01g or 0.1g levels would start attacking lighter larvae.
The researchers noted that the baby fish had a “relatively small mouth”, so rather than swallowing their brothers and sisters whole, they would bite pieces out of them. Despite this limitation, the fish caused plenty of deaths --- up to 12 per cent of the deaths that happened in the lab each day.
Those fish that grew fast enough to be able to chew on their fellows had an advantage. The extra food accelerated their growth and development. Tiger puffer fish are likely to be faster and swifter, so they can deal better with enemies.
As the name suggests, puffer fish can inflate to make themselves seem much larger than they really are, thus scaring off enemies. They do this by filling their stomachs, which are extremely elastic(弹性的), with water. If that’s not enough of a threat, the tiger puffer fish --- like most of the other puffer fish in the family --- carries a deadly toxin(毒素). Eat one puffer fish and the poison will paralyze (瘫痪) your muscles, including the muscles responsible for breathing, so death is usually caused by a lack of oxygen. Famously, the fish is a delicacy in Japan, where highly qualified chefs produce dishes that contain the safe level of the poison. Interestingly, the puffer fish does not go to the trouble of producing the poison itself. Instead, it hosts bacteria (细菌) that produce the stuff. It obtains these bacteria from its diet, so the youngest adult fish are not poisonous.
【小题1】All of the following statements account for the violence of puffer fish except that_____.

Social networking isn’t only for the under 40s. More than 25 percent of Americans 50 years and older stay connected using sites such as Facebook, MySpace and Twitter, according to new research.
“The latest data tells us that more and more social networking is becoming a part of everyday life for Americans 50 plus,” said Kevin Donnellan, the chief communications officer at AARP, which released （发布）the report.
Nearly a quarter of older Americans are on Facebook and 73 percent said they use it to stay in touch with relatives, but not just their children and grandchildren. “They are using the Internet to keep up with the world and the people who are important to them,” said Jean Koppen, the author of the report. She added that older adults are also on Facebook to stay connected, not only with their family, but with their friends and those in the same age group. Almost 50 percent of older adults were introduced to the social networking sites by a family member, mainly a child or grandchild. “Just under one-fifth of adults aged 50 and older say they do not use the Internet,” according to the report.
The findings are based on a telephone survey of 1,863 adults. In addition to keeping up on Facebook and Twitter older adults are aware of the latest technology. Eighty-three percent had heard about the Apple iPad and 11 percent intended to buy one.
Despite the popularity of the Internet among the over 50s, they still mostly go to print newspapers and magazines for news. Only one percent said they followed blogs.
