It is autumn. A strong wind is blowing. It   (1)   flower seeds（种子）high in the air. One of the seeds is tiny. Will it be able to keep up   (2)   the others? Finally the wind stops and seeds fall quietly down on the ground.

Now it is   (3)  . After a long trip the seeds feel very   (4)  . They look just as if they are going to sleep in the earth. Snow falls and covers them like a soft white blanket.

Spring comes. It gets warm. The sun shines. Rain falls. The seeds grow   (5)   full and round that they start to break open a little. Now they are not   (6)  . They are plants. First they put roots (根) into the earth. Then their little stems（茎）and leaves begin to dance in the sun and air.  

In summer, the tiny plant is all alone. It grows on and doesn’t stop. The sun shines on it   (7)   the rain waters it. It has many leaves. It grows taller and taller. It is   (8)   the people. It is taller than the trees. And now some flowers grow on it.

Autumn comes back. The wind blows past the flowers.  (9)   petals (花瓣) drop over the land and down to the ground. The wind blows harder. The flowers have lost all of their petals. Once more the wind shakes the flowers, and this time the flowers’ seed pods (荚) open. Many new seeds come out. Quickly in the wind they are   (10)   to new plants again. 

Waste can be seen everywhere in the school. Some  (1)  ask for more food than they can eat , some students don’t  (2)  to turn off the water taps after they finish washing, and others often forget to turn off the  (3)  when they leave the classroom. They say these things are cheap,  (4)  I don’t agree with them.Waste can bring a lot of problems. Though China is rich in some resources (资源), we are  (5)  of others. It is reported that we will have no coal or oil to  (6)   in 100 years. So if we go on wasting our resources,  (7)  can we use in the future and where can we move? Think about it. I think we  (8)  say no to the students who waste things every day.  (9)  should stop wasting as soon as possible. If we do our best, waste can be stopped  (10)  and many natural resources can be saved.

In China, spring returns in March. The weather gets warm.   (1)    comes back to life. Trees turn green and flowers come out. It is a wonderful season.

Summer begins in June. It is very hot. It often rains and sometimes it rains   (2)    .

Fall comes after summer. It is the harvest season，and the farmers are busy harvesting. It’s cool and   (3)    fall from the trees. The cold weather is coming.

Winter lasts   (4)   December to February. It’s a very cold season. We had better wear    (5)    clothes. The wind blows strongly and sometimes there is ice and snow.

As we know, life today has many problems. One of the biggest is____36_____, such as water pollution, air pollution, __37__ pollution and so on. Water pollution makes our rivers and lakes __38__. It kills our fish and pollutes our drinking water. Air pollution is the most serious(严重的) kind of pollution. __39__bad for living things in the world. Noise pollution ___40__ us talk louder and makes us become angry___41___．The Earth is__42___ home and we must save it. We canˈt __43__ waste here and there. We should go to work and school by bus___44__ with our friends in the same car. Everybody__45_  save the Earth.

As we all know, the environment around us is getting  (1)   .Recently, a new lifestyle called low-carbon life is   (2)   every corner of our country. The meaning of low-carbon is  (3)   energy and no waste. There are many ways to promote it.

First, we should set up a no-car day every week in our school, because cars not only cause serious   (4)   pollution but also waste energy . On the no-car day , neither students nor teachers are   (5)   to drive to school. They can just walk or run. Use our   (6)   and enjoy the fun.

Second,we had better not use plastic bags any more. No one can stand the “  (7)   pollution “, so it is wise to use cloth bags which can be   (8)   again and again.

Finally, one thing that we should   (9)   is that every big thing comes from the small details. For example, we ought to turn off the lights the moment we leave, use both sides of the paper, and so on.

All in all, it weighs greatly for all of us to put the low-carbon lifestyle into practice. Just set our mind to these: no-car days, no plastic bags and no   (10)   . Let’s do it now.

The earth is our home. We must take care of it. Life today is easier than it was   (1)   years ago, but it has brought some new problems. One of the biggest problems is pollution. We can see it, smell it, drink it and even   (2)   it.

Man has polluted the   (3)  . The more people, the more pollution. Many years ago, the problem was not so serious because there were not so   (4)  people. When the land was used up (用光) the river was not clean in a place, man went to   (5)   place. Now man is slowly polluting the whole world.

  (6)   pollution is still the most serious, it’s bad for  (7)  things in the world. Many countries don’t let people burn   (8)  for air in houses and factories in the city. Pollution by SO₂ is now the most dangerous kind of  (9)  pollution. It’s caused by heavy traffic. People say it’s   (10)  to ride bikes. When you are   (11)  , there is no pollution. But even in developed countries, most people don’t go to work by bike. It’s not   (12)  bikes are expensive or people are tiered if they ride to work. It’s because the number of cars on the roads becomes larger. So more people   (13)  their bikes and go to work by cars, then things are getting  (14)  . We should have special roads only for bikes and make it  (15)  difficult and expensive for drivers to take their cars into the city that they will go back to use their bikes.

Protecting wild animals is our duty. Because wild animals are important to us. They live with us on the earth together. If there are no animals on the earth, we will not live on,  33  . So we should take good care of them to help us live a good life.

 34   some people still don’t realize the  35    of protecting wild animals. They often kill wild animals for food or for money. Every day there are many wild animals being  36   . So lots of wild animals have died out. We can’t see them any more. Today the number of wild animals  37   becoming smaller and smaller. If we don’t protect them, they will all die out. If this goes on, there will be no animals left on the earth.

 38  , more and more people have begun to do many things to help protect wild animals. They ask people  39    killing wild animals. They get people to know that protecting wild animals is one of the most important things.

Now many countries have made some laws to protect wild animals.

Since wild animals are so important to man, we should do our  40    to protect them and it means human beings can make friends with animals and get on well with them.
