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 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.

Sally went to the park with her mother at weekends. They enjoyed the sun and the fresh air at first. Then Sally became very___36___. “What’s wrong, Sally?” asked her mother. “__37___! Rubbish is everywhere. There are used boxes, used bottles ___38___ waste paper on the ground,” answered Sally. “The park is too ___39___,” said her mother. “Yes, let’s do something for it,” said Sally.

Sally and her mother went home. Sally painted a picture of a park. Then she ___40___ “PLEASE KEEP OUR PARK CLEAN” at the top of her picture. Then Sally returned to the ___41___ and put up her picture on a big trash can. Then she ___42___ her mother, “Will you help me pick up the trash?” “I sure will!” said her mother.

The children in the park ran over to see what was going on. Julie invited them to pick up the __43___ together. And then they talked and laughed as they ___44___. Soon all the waste bags were full.

“We need to come back other days. There’s still some trash on the ___45___,” said Sally. “But the park looks much better.”

“Yes, it does,” said her mother. “I’m so proud of you, my dear.”

Zhejiang is one of China’s major tea-producing areas and Longjing tea is 51 as China’s best green tea.

Longjing tea became important over three centuries  52 , during the Qing Dynasty .It is said that when the famous emperor Qianlong(乾隆)went to visit Hangzhou, he always  53  Longjing tea there. He enjoyed it so  54  that he named eighteen Longjing tea plants as producers of “imperial (皇家的）tea”.

  55   , one kilogram of Longjing tea is made up of about seven thousand tea leaves. Nowadays,  56  most of the tea leaves are picked by machine,some farmers still keep the tradition of picking the leaves by  57   . They say they can find leaves of the proper (合适的)color and size. Machines can pick leaves  58  than man, but they may not be able to classify (分类) them as well as man.

People  59  drinking in the tea house. This has been a  60    part of the life in Hangzhou since the Song Dynasty. At that time, Huangzhou was the capital of the Song Dynasty. Today, the tea house is one of the places where Huangzhou people most like to go.

As science and technology develop, our life is getting better and better. We are lucky that we can have many things. However, most of us usually   (1)   some things.

Electricity is one thing that we waste most. Lights, TVs,  _57_  and other things are often kept on even when no one is using them. We should turn them off when we do not need them. It __58 _ less than a second to do it. Anyhow, not wasting electricity saves money, because we do not have to   (2)   the electricity we do not use.

The second thing that we often waste is water. Fresh water is precious（珍贵的）, _ 60   it shouldn’t be wasted. It is only a simple matter of turning off a tap. I am sure _ 61_  can do this easily if he wants to.

  (3)   big waste is food. My mother   (4)   cook so much food that much of it was thrown away. I told her we had wasted so much food. She thought I was right and now cooks only what we can eat.

It is not   (5)   to be wasteful. I find there is a simple way of not wasting things. That is to use only what we   (6)  . In this way we can stop being wasteful.
