It's March, 2050. Frank and Mary Smith wake up in their comfortable house in the morning and turn on the bedroom computer to get the latest news. They get used to reading The Times over the years. The only difference is that they changed to electronic newspapers many years ago.

    After breakfast, as they watch the screen, Mary orders the household robot to make coffee for them. Frank is a computer engineer, working for several companies. He goes into the study to take part in a video conference with his partners around the world.

    Mary takes a quick look at the shopping channels at home before beginning the video call to talk to her assistant. She also has a job and she is doing medical researches.

    Frank and Mary have one daughter, Louise, who also has her own work station at home. She goes to school only one day a week, mainly to play with other students. Louise is studying Chinese at present. Chinese has become an important language in the world.

    According to the family doctor, Louise will live to at least 130 years old. Her wish is to work for a few decades(十年)and then spend her time on music and painting.

It was raining heavily as I was walking up the hill towards the station at six o'clock on a Saturday morning. At this early hour there wasn't much traffic and there weren't many people. Just as I was crossing the road near the top of the hill, a car came around the corner. It was traveling very fast. Suddenly it hit a lamp post and turned over.

    I ran to the car to help the driver at once. He was badly hurt and there was a lot of blood on his face. A young woman hurried into the station and phoned for an ambulance, while I took care of the driver. Many people came to see what happened. A policeman arrived a few minutes later and asked me a lot of questions about the accident. After a while the ambulance arrived and the driver was sent to the hospital.

    On Monday morning I went to the hospital to see the man. The doctor told me that he was much better, and he would leave the hospital after a few day's rest.

One day,Jack drove his new car very happily down a street. Suddenly from his car came a terrible sound. He felt1 ,so he stopped his car and looked around. A child2 beside his car with a few stones in his hand. He jumped out of the car and found a dent(凹痕) in the door. He was so angry that he caught3 child and shouted at him,"Who are you? Why did you hit my new car4 a stone?"

"Please , sir , please ... I am sorry! But I didn't know 5 else to do," said the child. "I threw the stone because I wanted you6 me. I need your help!" Tears ran down the7 face. He said,"My brother fell out of his wheelchair and was almost under it. He is hurt but I can do nothing8 he is too heavy for me. Could you give me a hand to get him back into his wheelchair?"

After hearing this,Jack hurried to help. He lifted(抬起)the child's brother gently back into his wheelchair. He looked over the boy9 to make sure that he was OK. Then he watched the child push his brother towards10 home. Suddenly the child turned around and bowed(鞠躬) to Jack. Jack felt pleased and excited. He looked at the dent in his car and smiled.

Nature is amazing! Take a close look at the world of insects, and you'll discover many unbelievable things. Consider butterflies (蝴蝶), for example. They have beautiful wings and magical flying skills. On summer days, you always see them flying freely over flower gardens and wild fields.

But did you know how butterflies become the flying insects? It is one of the wonders of nature. In the beginning, the mother lays a small and colourful egg on a leaf or stem of a plant. It is hard to believe that the egg will become something completely different in a few days. It becomes a walking insect. This insect is called a caterpillar. It now has legs, eyes and a large body. A new life begins. The caterpillar can eat, walk and see. But it is still not a butterfly.

Soon, after growing big, the caterpillar makes a cover for itself. It covers itself in the nice protective blanket (保护层) and goes to sleep. This is known as the "pupa (蛹)" stage. After some time, the blanket breaks and a wet butterfly appears. It now has six legs, a mouth, eyes and wings. Shortly, the beautiful butterfly spreads (张开) its wings and flies away. After a few weeks, this butterfly lays her eggs, and the cycle (循环) begins all over again.

This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things.

Hi, everybody. Here we're in front of the South Gate. Go straight on, and you'll find the Panda House. Pandas are cute. They like to eat bamboo and lie down all day long. Every year, lots of visitors come here to see them. 

Walk along the road. To the north of the Panda House, you'll find the lions. Lions are the kings of the animal world. Remember that they're dangerous. Never go near them. 

Turn left, and to the west of the Lions' Area, you'll find the World of Birds. Birds make beautiful sounds when they sing. To the north of the World of Birds is the Monkeys' Forest. Monkeys are clever and funny. They jump around and make people laugh. 

Then turn right, and to the east of the Monkeys' Forest, you'll see the giraffes(长颈鹿). They're quite tall. Their long necks help them eat the leaves from trees. 

Northeast of the giraffes there's a bridge. Cross the bridge, and you'll see the elephants. Their large ears are like open fans. 

Here you can see all kinds of animals. Have a nice trip!
