Sports are very important to us. Sports are popular with young and old people. Many people do morning exercises, go to different sports clubs and take part in sports games. Other people like sports too but they only like to watch sports games and listen to sports news. They don’t do sports.

P.E. is an important subject in our school. Students have P.E. classes five times a week. Boys and girls often play volleyball in P.E. classes. There is a big playground in our school and students like to do sports there. Our school has a lot of sports games and many students take part in them.

Sports can help people to keep healthy. People of all ages must take care of their health and do exercise regularly (有规律的). My favorite sport is swimming. I go to the swimming pool once a week. But I like relaxing by the lake or the river and swimming there.

What is the sky? Where is it? How high is it? What lives above it? These questions are difficult   (1)  ,   (2)   they?

Is the sky blue?

The sky   (3)   no color. We know that there is air around   (4)   world. When planes fly, they need air   (5)   their wings. Planes can not fly very high because when they go higher, the air gets   (6)  If we go up about 1,200 kilometers   (7)   the earth, we find there is   (8)   air at all.

Maybe we can answer   (9)   of our questions now. The sky is space.   (10)   space there is only the moon and all the stars.

    We have all looked up at birds and wished that, like them, we could fly off into the sky. ____56____, we will never he able to fly. And penguins(企鹅). ____57____ they are birds themselves, share the same life. Like us. they have to ____58____ around while other, luckier birds mockingly(取笑地)circle overhead.

    But penguins are birds, aren't they？ So ____59____ on earth can't they fly？ Professor John Speakman, from the University of Aberdeen. asked himself the very same questions. According to BBC, he said, "Like many people. I've always been ____60____ penguins, and seeing them do these marches across the ice, I've often thought, "Why don't they fly？"

    Now, it seems, there is ____61____ to this question. By looking all other kinds of birds, scientists like Speakman are beginning to find out why penguins can't fly. Penguins use their wings to ____62____—they are amazing swimmers. A wing that is good for swimming cannot be good for flying.

    This is called an evolutionary trade-off(进货的权衡). Penguins certainly used to fly. But as time ____63____, they began to find more and more food in the sea. Over millions of years, they had spent so ____64____ time under the waves that they'd forgotten how it feels to fly.

    Don't feed too bad for the penguins. They probably don't even want to fly. ____65____, in many ways the ocean is a better place than the sky could ever be.

We are talking about the year 2050. “What will our country be   (1)   in the year 2050”. No one    (2)  , but it is fun to guess. In the year 2050 everybody will   (3)   a pocket computer. The computer will   (4)   people the answers to all their questions.   (5)   telephones in our pockets too and will be able to   (6)   our friends to   (7)   them at the same time. Machines will do   (8)   of the work  (9)   people will have more holidays. Perhaps they will work only two or three days a week. They will be able to fly to the moon   (10)   and spend their holidays there.”

Robots seem very new to most people. But they have a  31   history. The  32   one was made by a Greek inventor(发明家). You may  33   robots in some films. The robots in these  34   are stronger, faster and cleverer than people. In real   35  , most robots are used infactories. They are used to do many dangerous, difficult or boring  36   . Some people can’t look after    37    and robots are used to help them. For example, some people can’t see. Many of these people use a  38   to help them move around. This dog is called a guide dog.  39    are making a robot to help them. In the future, robot dogs  40   take the place of(代替) these guide dogs.

Robots are also   41     in American hospitals. At one hospital, a robot takes meals  42   the kitchen to the sick people’s rooms. It  43   loses its way because it has a map of the hospital in its computer system(系统).

In the future,  44   will work in space. But robots will never take the place of human. They can  45   us in a lot of different ways.

The earth is our home. We must   41  it. Life today is easier than it was millions of years ago, but it has brought some new problems. One of the biggest　 42  is pollution.

Man has polluted the earth .The more people, the more pollution. When the land(土地) was used up or the river was not clean in a place, man went to　  43  place. Now man is slowly polluting the whole world.

Many countries don’t let people burn(燃烧) anything bad for air in houses and factories in the city. Pollution by SO2 （二氧化硫）is now the most dangerous kind of　  44  pollution. It　  45  by heavy traffic. People say it’s best to　  46  bikes. When you are riding, there is　  47  pollution. But most people don’t want to go to work by bike. It’s not because bikes are expensive　  48  the number of cars on the roads is becoming larger. So more and more people go to work by car. Then things are getting　  49  . We should have special roads only for bikes and make it　  50  difficult and expensive for drivers to take their cars into the city that they will go back to using their bikes.
