It may be difficult to start high school. Thinking about making new friends might make you feel nervous.{#blank#}1{#/blank#}You are going to school with a group of students of your age. Here are several suggestions for you to follow.

    Forget your fear and just talk to someone. It's easier said than done. But try to take a deep breath and find your voice. Don't be afraid to approach (接近) people.{#blank#}2{#/blank#}Sit in the middle of the classroom with as many new friends around you as possible.

    {#blank#}3{#/blank#}Take part in after-class activities that interest you. Try to make friends in the clubs. If you don't join anything, you will be just going to class and then going home. Being in a club makes you more social.

    Stay clean. No one likes a bad smell that could knock someone over. Shower every day, brush your teeth and wash your hair.{#blank#}4{#/blank#}

    Be respectful (尊重的) of people's differences.{#blank#}5{#/blank#}And everyone believes in different things. It is a good thing to have different friends with different opinions because you can each share your own.

    The world is in danger. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 860 remain(剩余). The others have been destroyed(破坏) by man. We are changing the earth, the air, the water and everything that grows and lives. We can't live without these things. If we continue doing like this, we will destroy ourselves.

    What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation(对自然环境的保护) is necessary. Many are helping to save our world. They plant trees and protect animals in forest. In a small town in the United States, a large group of volunteers cleaned the banks of their rivers. Young people may hear about conservation through a record called No One's Going to Change Our World. It was made by the Beatles, Cliff Richard and other singers. The money from it will help to protect wild animals.

    Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves. Some birds love eating locusts (蝗虫), but birds cannot easily catch them, why? It is because locusts change their colours with the change of the colours of crops. When crops are green, locusts look green. But as the harvest (收获) time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for living and appear only at night.

    If you study animals' life, you'll find the main use of colour is to protect themselves. Bears, lions and other animals move quietly through the forests and they cannot be easily seen by hunters. This is because they have the colours much like the trees.

    Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体) when it faces danger. While the liquid spreads, its enemies cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

Here is a story: A man sees a butterfly (蝴蝶) . The butterfly tries to get out of its chrysalis (蛹) . F{#blank#}1{#/blank#}sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out e{#blank#}2{#/blank#}. Surprisingly enough, the butterfly is unable to fly. If the butterfly doesn't struggle (挣扎；奋斗) to leave the chrysalis, it can't fly！The struggle develops the e{#blank#}3{#/blank#} in the butterfly which makes it fly. Similarly, the challenges of life bring out the best in young people and make the fly.

When people are young, meeting and overcoming challenges will make them s{#blank#}4{#/blank#} and ready to face life.

When we look at successful people, we see that the most successful of them are people who have had to struggle.

One famous businessman, who now o{#blank#}5{#/blank#}many big supermarkets, used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. He had to b{#blank#}6{#/blank#}up a big family. He took up the challenges and overcame them. Today his brothers and sisters are leading s{#blank#}7{#/blank#} lives.

Sometimes challenges do not appear to us because we keep away from them. So, some parents and teachers actively encourage young people to face challenges. They might organize some a{#blank#}8{#/blank#}for young people which provide them with challenges, like rock—climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of t{#blank#}9{#/blank#}. For countries to continue to become successful, it is i{#blank#}10{#/blank#}that the young people learn to meet challenges and overcome them.

Life in the future will be different from life today. Many changes will happen. But what will the changes be?

The population (人口) is growing fast. There will be more people in the world and most of them will live longer than people live now. 

Computers will be much smaller and more useful, and there will be at least one in every home. And computer studies will be one of the important subjects in school then. People will work fewer hours than they do now and they will have more free time for sports, watching TV and travelling. Travelling will be much cheaper and easier. 

There will be changes in our food, too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead (相反), they will eat more fruit and vegetables. Maybe people will be healthier. Work in the future will be different, too. Robots will do dangerous and hard work. Because of this, many people will not have enough (足够的) work to do. This will be a problem.
