Animals are important in Indian culture and are treaded in a special way. For example, a lot of elephants aren't . they are domesticated(驯养). They aren't kept as pets, but as working animals. Every working elephant its own keeper. An elephant and its keep meet for the first time when they are both young, and they grow up together. In fact, their relationship continues for the rest of the elephant's perhaps 40 years. Lots of elephants work in the forest, moving heavy when they are cut down. Some give rides to tourists, or people during celebrations and festivals. Keepers take excellent care of their elephants , feeding them and giving them a bath at the end of the working day.
special animal in India is the cow. Cows are protected animals, they aren't kept on farms or killed for food, although people do use their milk. So in India you can often see cows walking around towns and cities, and nobody tries them. If they sit down in the middle of the road, people drive around them! Do you think it's interesting?

Have you ever wanted to achieve something really amazing in life? Well, Greg Mortenson wanted to climb a mountain, but he ended up helping thousands of people to have a better life.
Greg's story began with failure. In 1993, he set out to climb K2, the world's second highest mountain. But Greg never made it to the top. After five days, he stumbled(踉跄)into the village of Korphe in northern Pakistan, injured(受伤)and hungry. The kind villagers there looked after him for several days.
Greg saw that the villagers were very poor and hungry, and some of them were ill. Also, the village school didn't have a roof(屋顶)and the children wrote on the ground with sticks. Greg knew he wanted to do something to help. " I'll build you a school,”he told the villagers. “ I promise.”
Greg went back home to the USA to raise money for the school. He even lived in the car to save money! Finally he went back to Korphe and built the school. But this was just the beginning of something bigger! Since then, Greg's organization has built around 80 schools and runs many others in Pakistan and other countries, too.
Greg hasn't finished yet. He does many other things to help people in poor countries. He has got many prizes, but it's the smiles of the children he has helped that makes him happy!
Greg has just written a best-selling book about his story called Three Cups of Tea. It's an interesting and exciting book which tells us what ordinary(普通的)people can do with courage and determination(决心)!
Today there are many fires than in the past. Over 100,000 wildfires burn each year in America. Russia has 20,000 to 35,000 wildfires every year. Australia has on average 60,000 each year. These fires destroy(损害)huge areas of forests and burn hundreds of homes.
Many experts believe there are several reasons for this sudden increase in fires. The first reason is climate(气候)change. Recent weather has been warmer and drier. This leads to dangerous fire conditions. When lightening strikes(发生雷电),dry grass easily catches fire. Hot winds add to the problem. The wind spreads a fire quickly. In 2010, Russia had the hottest and driest summer in a century. In just one month, 500 fires destroyed over 2,000 homes. Some people lost their lives.
Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fire. They didn't allow the grass and trees to burn. As a result, today many forests have thicker vegetation(植被).Thicker vegetation means more fuel(燃料)for fires. Also, without fires from time to time, forests become overcrowded and unhealthy. Some trees are dead. The dead wood then easily catches fire. So surprisingly, America has many more fires today partly because of its past fire-fighting practices.
Scientists now understand that a fire can be a natural part of a healthy forest. As a result, countries like Australia allow more fires to burn naturally. Sometimes, fire fighters even start fires to get rid of(去除)dead wood. Of course, they carefully control the fires. The fire thins out old trees. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore, if a fire is not a serious threat(威胁)to people, firefighters may let it burn naturally.
The first part of a new science-fiction series (系列剧)was shown on NBC last night. Star Trek is about a spacecraft(宇宙飞船)which travels faster than the speed of light. The show is developed from three ideas about the 22nd century. First, we'll find other life forms great tools which will make amazing things possible.
Let's think about these predictions. If we find life forms on other planets, will they be intelligent? I hope so. But we human beings might not be friendly – I don't think we'll believe in the idea of peace one hundred years from now. But this is science fiction, so we can be optimistic! And Star Trek's idea of life in the future is "communicators". And we will be ablt to have conversatins with people who are on because you'll have an electronic notebook. And if you get ill, the doctor won't have to examine you – a machine will "read" your body. The strangest manchine includes a "teleport" which will take people to a different placein a second!
The ideas are interesting, and in my opinion there's only one problem with star trek: the acting. The TV company (公司)will have to get better actors. If they do that, the show might be a success. If the acting doesn't improve, Star Trek won't last for more than one series. Of course, my prediction may be wrong. I can't see into the future!

Hip-hop Planet
Countries like France, Brazil and even Japan have their own hip-hop culture. But where did this strange speaking-singing style come from? Many centuries ago, in West Africa, traditional storytellers played musical instruments while they were telling stories. When this tradition travelled from West Africa to the USA, it developed into different musical styles. For example, blues and jazz. And in the 1970s, there were many poor areas in New York. There wasn't any money for music lessons in schools, so kids made their own music. Teenagers Afrika and DJ Here played their records outside in the streets. Everybody joined in. MCs had rapping(说唱) competitions. Every week, there were talented new dancers, new DJs and new MCs. Hip-hop culture was born.
It was 1980. I was at a party in New York. There was a young DJ at the party. He was playing records. While he was putting a record on, a kid picked up a microphone(话筒) and begantapping. Some other kids were break-dancing to the music. It was loud and boring, and I
hated it. I preferred jazz.
Today's successful American artists like Missy and her friend Tim heard it on the radio when they were growing up.
The last time I heard hip-hop, I was in West Africa. I was going to interview a traditional storyteller when I met a young hip-hop artist, He told me there are hundreds of rap groups in Africa today. We live on a hip-hop planet.
A.I remember the first time I heard hip-hop. B.You can find hip-hop everywhere you go. C.I was writing a book about African-Americans. D.Many Americans gave music lessons to poor children. E.These styles all started in poor African-American areas. F.During the 1980s, hip-hop became popular all over the USA. H.Some people don't like hip-hop because of its spoken words. |
