Life in the year 3044 is very different1 life in the 21^st century. We still do many of the things you did, but we do them 2. For example, we now have e-friends to help us and keep us company. An e-friend is a machine that looks just3a human being. It can walk and talk and can do almost4 we human beings do. My e-friend is a lot like me and we have5fun together. She helps me 6 my homework and we often go swimming.  She is programmed to take care of me if anything7, so I always feel safe when we are together.  She can also send me messages, just like old-fashioned e-mail, and I can download information from her memory. It's great8an e-friend. I am never lonely and I always have someone to talk9.

      I would like to tell you more about life in the year 3044, but I have to send my e-friend to clean up my room. Maybe10I will be able to travel back in time and visit you.

    Look at the koala! It is 1 lovely that I want to touch it. How much do you know about koalas, especially a baby koala? Let's look at it.

    A newborn koala is smaller than a peanut. For the first few months the baby 2 inside its mother's pouch(育儿袋), and drinks its mother's milk.

    By the age of 5 3, its eyes are open and it can look out 4 the pouch. It still stays there.

     About six months after the baby is born, it leaves its mother's pouch for the 5 time for a short time, but it hangs onto its mother's back.

    It is now about 500g. It comes in and out of the pouch. It keeps very close to its 6and returns to the pouch within a few minutes. Gradually the baby will stay out longer.

    By 12 months old, the baby wants to eat only eucalyptus(桉树) 7, no more its mother's milk. The mother koala begins teaching her baby which eucalyptus leaves are 8 to eat.

    A one-year-old koala can 9 on its own, 10 it doesn't often do that. Most young koalas stay with their mothers until they are two or three years old.

    Kingfishers (琴鸟) are small beautiful birds. They have blue bodies, and look 1 cute. Fish is 2 favorite food. They don't live 3 the trees. They live in holes (洞) in the riverbank. But kingfishers are in great 4 now. People change (改变) many rivers. The rivers have new riverbanks, 5 kingfishers are losing their 6. People also make many rivers very 7, so there 8 no fish in the river. There isn't 9 food for kingfishers. We must 10 kingfishers.

When man began to search the skies, he saw a lot of things. In the universe, the earth seemed to be just a small bit of dust. It is only a small planet, and travels around the sun. The sun together with its planets, travels in the Milky Way（银河）, our galaxy（星系）. The Milky way has about thirty billion stars like our sun, and is one of about a hundred million galaxies in the universe. Because the space is so great, it is difficult to work out how far away a star is. Instead of kilometers, we have light years. A light year means the distance light travels in one year. Our nearest neighbour galaxy is more than 9,000,000 light years away from the earth.

    We cannot stop earthquakes, but we can do things to make sure they do not destroy (破坏) whole cities. First, it is not a 1 idea to build houses along the lines where2of the earth's plates join together. Second, if you think there 3 be an earthquake, it is better to build houses on rock, not on 4. Third, you must make the houses as 5 as possible. Weak buildings will fall down in an earthquake, but strong ones may 6.

    Scientists are 7 that one day an even bigger earthquake will hit the part around S an Francisco. They call it “The Big One”. But people today are still building more 8. The population in and around San Francisco 9 is ten times more than it was in 1906. This means that 10 there is another earthquake, a great many houses and buildings will be destroyed.

    It was a fine spring day for a walk down the street. A mother and her two little girls walked along the sidewalk, happily laughing. 1 , hundred small alien ships appeared on the horizon. It started 2off some electric rays. People screamed. Children cried. There was 3 everywhere.

    There came the tingling sound of glasses, breaking everywhere. People fled in every 4. The mother was jostled(推) and lost hold of her5. She raced around shouting and crying for her kids. She thought they were lost to her forever.

    The sky cleared up. The aliens were 6. But there was no sight of the children. Heart-broken, the mother reached her house, crying her eyes out.

    She heard someone 7 "Mamma". Was it her kids? She frantically(发狂似地)8 around. There they were! Hand in hand they came running towards her. She ran towards them too. Her arms stretched out 9 to hug them. She opened her eyes. The pillow was wet. It was a dream!

    She raced to the kids' bedroom. Her lovely girls were sleeping peacefully. She kissed both their foreheads and 10"love you".
