Our sun is a star, and nine worlds move round it. Worlds like these are planets (行星).

But there are other stars, other suns. Not only thousands of them, but millions of them. Do different stars have planets? We can see the planets round our own sun. But we haven’t seen any more. The stars are too far away from us. Stars give out (发出)light, but the planets don’t have any light of their own. So we can’t see them. They’re too far, and too dark.

Still, we can tell that some stars have planets. While a big planet goes round, it pulls its star to one side. And sometimes we can see this, Then we know that the star has a planet.

For example, Barnard’s Star(巴纳德星)is a small red star. And it is the quickest star in the universe. But sometimes it moves slower, and then quicker again. We have know Barnard’s Star for many years, and now we are sure it has a planet.

My house is made out of wood, glass and stone. It is also made out of software.

If you come to visit, you’ll probably be surprised when you come in. Someone will give you an electronic PIN (个人身份号码)to wear. This PIN tells the house who and where you are. The house uses this information to give you what you need. When it’s dark outside, the PIN turns on the lights nearest you, and then turns them off as you walk away from them. Music moves with you too. If the house knows your favorite music, it plays it. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.

Of course, you are also able to tell the house if you want something. There is a home control console (控制台), a small machine that turns things on and off around you.

The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works for you because you have the keys. My house works for you because you wear the PIN or hold the console.

I believe that ten years from now, most new homes will have the systems that I’ve put in my house. The systems will probably be even bigger and better than the ones I’ve put in today.

I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, “How will I live without them?”

1.What does the passage mainly discuss?

A.How to develop a new system.

B.The function of the PIN.

C.A home for the future.

D.Easy life in the future.

2.What’s the purpose when the writer wrote the fourth paragraph?

A.To let readers know why his ideas are new.

B.To let readers know how special his house is.

C.To explain the importance of the PIN and the console.

D.To explain more easily what the functions of the PIN and the console are.

3.The writer’s new house is different from ordinary ones mainly because _____.

A.it has been controlled by computers

B.you can make a telephone call anywhere

C.it has your favorite music following you

D.the writer is able to change his new idea into practice

4.What is the writer most likely to be according to the passage?

A.An IT expert.

B.A famous doctor.

C.An idealist

    You either have a sense of direction,or you don’t.But why is it that some people could find Their way across the Sahara without a map,while others can lose themselves in the next street?

    Scientists say we’re all born with a sense of direction,but it is not properly understood how it works.One theory is that people with a good sense of direction have simply worked harder at developing it.Research being carried out at Liverpool University supports this idea and suggests that if we don’t use it,we lose it.

    “Children as young as seven have the ability to find their way around.”says Jim Martland,Research Director of the project.“However,if they are not allowed out alone or are taken everywhere by car,they never develop the skills”

    Jim Martland also emphasizes that young people should be taught certain skills to improve their sense of direction.He makes the following suggestions:

    ●If you are using a map.turn it so it relates to the way you are facing.

    ●If you leave your bike in a strange place.put it near something like a big stone or a tree.

    Note landmarks on the route as you go away from your bike.When you return,go back along the same route.

    ●Simplify the way of finding your direction by using lines such as streets in a town,streams,or walls in the countryside to guide you.Count your steps so that you know how far you have gone and note any landmarks such as tower blocks or hills which Call help to find out where you are.Now you will never get lost again !

60.Scientists believe that            .

    A.some babies are born with a sense of direction

    B.people learn a sense of direction as they grow older

    C.people never lose their sense of direction

    D.everybody possesses a sense of direction from birth

61.What is true of seven—year—old children according to the passage?

    A.They never have a sense of direction without maps

    B.They should never be allowed out alone if they lack a sense of direction.

    C.They have a sense of direction and can find their way around.[来源:Zxxk.Com]

    D.They can develop a good sense of direction if they are driven around in a car.

62.If you leave your bike in a strange place,you should         .

    A.tie it to a tree so as to prevent it from being stolen

    B.draw a map of the route to help remember where it is

    C.avoid taking the same route when you come back in it

    D.remember something easily recognizable on the route

63.According to the passage the best way to find your way around is to      .

    A.ask policemen for directions

    B.use walls,streams or streets to guide yourself

    C.remember your route by looking out for steps and stairs

By 2050

Futurologists predict that life will probably be very different in 2050.

TV channels will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.

Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.

Robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots—they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.

Medical technology will have conquered many diseases. Today, there is equipment that connects directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.

Scientist will have discovered how to control genes(基因). Scientists have already produced clones(克隆) of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
