Man has invented four kinds of satellites. The first kind of satellites studies the1of the earth. They are used to make maps. They also help countries to see where they can2oil or gold.

    The second kind of satellites is used to3ships and planes. A ship or a plane can send a message to the satellite and can find out4it is.

    The third kind of satellites studies the weather. These satellites5clouds and strong winds moving across the earth. They warn countries to make preparations when very6weather is coming. They7of the earth from thousands of miles above it and send the photos to weather stations on the ground.

    8kind is used for communication. Telephone calls9countries can be sent by these satellites. Some can carry hundreds of calls at one time. The call is sent to the satellite then the10sends it to a station in the country and this country is being phoned. These satellites also carry pictures; they can receive and send about eight programs at a time.

    In some science fiction films, people in the future have their own robots. These robots are just like humans. They help with the housework and do the most1 jobs.

    Some scientists believe that there will be such robots in the future. However, they agree it may take hundreds of years, Scientists are now trying to make robots look like people and2 the same things as us. Japanese companies have already made robots walk and dance. This kind of robot will also be fun to watch.

    But robot scientist James White disagrees. He thinks that it will be3 for a robot to do the same things as a person. For example, it's easy for a child to4and know where he or she is. Mr White thinks that robots won't be able to do this. But other scientists disagree. They think that robots will be able to talk to people.525 to 50 years.

    Robot scientists are not just trying to make robots look like people. For example, there are already robots 6 in factories. These robots look more like huge arms. They do simple jobs over and over again. People don't like to do such jobs and will get bored, But robots will7 get bored.

    In the future, there will be more robots everywhere, and humans will have8 work to do. New robots will have many different9. Some will look like humans, and others might look like10 ， After an earthquake, a snake robot can help look for people under buildings. That may not seem possible now, but computers, space rockets and even electric toothbrushes seemed impossible a hundred years ago. We never know what will happen in the future!

    In real life, robots are mainly used in factories. They do many different jobs. Usually these jobs are too 1, difficult or boring for humans.

Robots also help disabled people and people who cannot look after 2. For example, scientists are making a robot to help 3 people. Now many of them have a dog to help them. The dog is called a guide dog. In the future, guide dogs might be robot dogs.

One robot dog is called Meldog. It has wheels. It usually "walks" 4 its owner. It is very clever. It knows the speed of its owner's walk. Meldog talks to its owner by 5. The owner wears a special belt. This belt 6 instructions to the owner from Meldog such as "Stop here", "Turn left" and "Turn right".

    In the United States, another 7 of robot helps disabled workers. This robot, called Kilroy, helps disabled computer operators. The robot 8 the sound of its owner's voice. It follows instructions such as "Turn the page" and "Make a cup of coffee".

    Robots are also used in American 9. They can do simple jobs. For example, they shave (刮脸) patients and brush their teeth and take meals from the kitchen to patients' rooms. It never gets lost 10 this robot has a map of the hospital in its computer memory.

    My name is Peter. I'm from New York and I am in Qingdao with my parents and my sister Lily now. My sister is eleven and I am twelve. We are in the same school. We go to school from Monday to Friday. Our parents are busy working and they don't have time to drive us to school. So we often go to school by bus. Sometimes we also ride a bike to school. We have four classes in the morning and two in the afternoon. My favorite subject is math. Science is my sister's favorite.

    I like sports. I like playing soccer and basketball very much. But I don't have much time to play them on weekdays. I help my sister with her math on Mondays, go shopping with my mother on Wednesdays, and practice Chinese on Friday afternoons. My Chinese friends help me with my Chinese. But on Saturdays and Sundays I can play sports, watch TV and surf the Internet.

A better town for teenagers

    I believe there are many things that we can do to make life in our town a lot better for teenagers.

    First of all, I think more bike lanes should{#blank#}1{#/blank#}(build). A lot of teenagers in my town ride bikes everywhere, but it's very{#blank#}2{#/blank#}(danger) because there is a lot of traffic. If there are more bike lanes in the future, it will be much {#blank#}3{#/blank#}(safe) for us.

    {#blank#}4{#/blank#}(two), I believe that we need more places for teenagers to go to.{#blank#}5{#/blank#}my opinion, teenagers won't cause problems in the street if there are more places for us to go to. So we need more{#blank#}6{#/blank#}(club) and other places where we can meet.

    Thirdly, teenagers here need more sports facilities. There{#blank#}7{#/blank#}(be) places to play ball games so far like tennis and basketball, but what about other sports,{#blank#}8{#/blank#}skating and rollerblading?

    Finally, I'm sure we'll make the town better{#blank#}9{#/blank#}we don't drop litter. If we all do something{#blank#}10{#/blank#}(help) now, our town will be much better for everyone in the future.

    Near the village, there is an old famous temple. Some people want to build a new house where the temple now stands, because they can find no other area to build them, while others disagree with them. They meet to decide how to solve the problem. Here are their opinions about it.

The expert wants to protect the temple and believes that there are some interesting things buried in the ground. If it is destroyed or moved, people may never learn about how people lived in the past.

The businessman thinks that the houses should be built. History is important, but we must think about the future. The village needs development and building new houses will offer jobs to hundreds of people.

Villager A says, "We should build the new houses because we need houses to live in."

Villager B says, "We should protect the temple because it can attract many tourists to come for a visit. If the temple is destroyed or moved, we will lose a lot of business."

The village leader thinks that he has a duty to make life better for the villagers. They need jobs and new houses. He also thinks the cultural site (遗迹) is important and they should be careful with it as well.
