Tea, coffee and cocoa are three major drinks all over the world. Tea is drunk by the largest number of people in the world. Tea, as well as silk and porcelain, began to be known by the world over a thousand years ago and has been an important Chinese export since then.

   Tea has a history of over 4, 000 years and China is the home of tea. In ancient China, tea was used as a kind of medicine, while nowadays people drink tea daily. Longjing, Pu'er, Wulong and Tieguanyin are all famous tea. Thanks to the mild climate and rich soil in Fujian, Zhejiang and Yunnan, tea is produced mainly in these provinces.

   The words for tea in different languages came from Chinese, like “cha' i” in Russian. And the Japanese character for tea is written exactly the same as it is in Chinese.

   Over the past centuries, Chinese people have developed their unique(独特的)tea culture, which includes tea planting, tea-leaf  picking, tea making, tea drinking and so on. Tea is also popular in some sayings, like “A friendship between gentlemen is like a cup of tea.” In dances, songs, poems and novels, tea is often mentioned, too.

    Death Valley is a huge place. It is more than 225 kilometers across the southern part of the state of California, and across the border (边界) with the state of Nevada.

    {#blank#}1{#/blank#} It can be dangerously cold during the winter months. The air temperature during the summer can be as high as 57℃. The heat of Death Valley has killed people in the past. It will continue to kill those who do not honor the climate. Death Valley does not forgive (原谅) those who are not careful.

    Death Valley was named by a woman in 1849. {#blank#}2{#/blank#} Thousands of people from other parts of the country traveled to the gold mining (开采) areas in California. They were in a hurry to get there before other people did.

    Many people were not careful. They made bad choices or wrong decisions. One group of people had reached Death Valley by December. They avoided the terrible heat of summer, but there was not enough water. There were few plants for their work animals to eat. The people could not find a pass through the tall mountains to the west of the valley. {#blank#}3{#/blank#} They had to kill their work animals for food and began to walk out of the valley.

    As they left, one woman looked back and said, “Good-bye, death valley.” {#blank#}4{#/blank#}

A. Slowly, they ran out of food.

B. Death Valley has a long history.

C. The name has never been changed.

D. Death Valley is a beautiful but dangerous place.

E. That was the year after gold was discovered in California.

    A blind boy sat on the steps of a building with a hat by his feet. He held a sign which said, "I am blind. Please help me."

    There were only a few coins in the hat. A man was walking by. He took out a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words on it. He put the sign back so that everyone who walked by could see the new words.

    Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized(认出) his footsteps and asked, "Are you the one who changed my sign in the morning? What did you write?"

The man said, "I only wrote the truth. I said what you said, but in a different way."

    What he had written was, "Today is a beautiful day, but I cannot see it."

    Do you think the first sign and the second sign were saying the same thing?

    Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the beauty of the day, but the boy could not enjoy it because he was blind.

    Alice and John are in the music club at their school. Alice plays the violin and John plays the drums. There are two groups in the school music club: the training group and the concert group. Everyone starts in the training group!

    "When I first started to play the violin it sounded terrible!" Alice said. "My family asked me to practice outside."

    After a year's practice, Alice and John play much better. Now, they are both in the concert group and they are learning more difficult music. "We're learning the music from the film Pirates of the Caribbean. It sounds fantastic!" John said. "Playing in the club with other kids is a lot of fun."

    Playing an instrument (乐器) is not only fun. It also helps children learn to concentrate (集中注意力). "I have to concentrate when I'm practicing," Alice said. "And now it's easier for me to concentrate on my schoolwork."

    Playing an instrument can also help children become more confident. As John said, "I was scared when I played in front of a lot of people for the first time. But now I really enjoy it."

    Everybody hates rats. But rats may soon be man's new best friends.

    What happens after an earthquake? We send in rescue (援救) dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can't get into small space. So now a new research project is using a smaller animal to save lives: the rat.

    How does it work? First, the rat is trained to smell people. When this happens, the rat's brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat's brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.

    Although there are already robots which can do this job, rats are better. "Robots' noses don't work well when there are other smells around. Rats are good at that," says a scientist. Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don't need electricity.

    The "rat project" is not finished, but a scientist says, "It would be fantastic. A rat could get into space we couldn't get to and a rat would get out if it wasn't safe." Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).
