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)  .

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.

I was on my way back to the earth.

Suddenly, a UFO appeared and it made my  (1)  land on a small planet.

On the planet, an alien（外星人）met me. He looked very  (2)  . He took me to see his family and friends. I  (3)  that all the aliens had four eyes, two heads and six legs. They had a white body and they had no hair.

The  (4)  looked like a large tower and the  (5)  is quite different from that of the earth, so I felt very  (6)  .

Then, the alien took me to  (7)  on the planet in his spaceship. The planet was so   (8)  . The sky (天空）was very blue and the river was very clean. I loved the planet.

A few hours later, I flew back to the  (9)  in my spaceship. I told people about my exciting  (10)  but no one believed me, I didn’t believe it either because it was just a dream.

The earth is our home. Our home is both very large   (1)   rich. We have mountains, rivers, lakes, forests and all kinds of natural resources(资源). We are proud of our home and we love our home.

      But at present, with the  (2)  of the world, more and more trees have been cut down, most of the water  (3)   polluted.  The natural resources are becoming fewer and fewer. What should we do? It’s time for us to take proper action to save the limited resources.

So it’ s very important that we all recycle. In nature, everything  (4)  again. For example, when   (5)   animal dies, it becomes  (6)  animal’ s food. Nothing is wasted. But humans have created things like plastic bags  (7)  can’ t be broken down by nature. Our rubbish kills animals and  (8)  water and soil.  (9)  we continue making too much rubbish, the problem will only get worse. If nature can’ t reuse the rubbish, we must recycle  (10)  .

 We should clean up the rubbish we’ ve made because nature can’t.

Recycling is also the right thing   (11)   for another reason. The earth is rich in natural materials like water and trees,  (12)  these materials are not endless. We use up our natural materials much  (13)  than the earth is able to reproduce them. For example, each year we cut  (14)     more than 6,000 square miles of forest. But it takes an average of 25 years for a new tree  (15)  .

Recycling can help us save the earth, so let’ s take action right now.

Dolphins are one of the cleverest animals in the world. We may hear of many stories about    36   dolphins save people out of water.

Dolphins have very good    39   . They use it to find things under the water. Many scientists also believe dolphins can even talk to each other through a    40   whistle (哨声).People from different areas don’t speak the same language. Just like people, dolphins’ whistles have many kinds. One day we may understand dolphins’ whistles, and then they will be able to    41    us about themselves.

Dolphins live in the sea,    42    they are not a kind of fish and they don’t lay eggs. They have babies in the same way as cows and cats do, and give their babies    43   . A female dolphin has a baby every two to three years.

Dolphins are very friendly.    44   , there are not many kinds of dolphins left. People    killed them for many years for food and other things. Now it’s time to    45    this and perhaps there will be more of them in the years to come.
