Jim Green has been in China for more than two years. He has been to many interesting    31 in Beijing, but he has not yet been to many other parts of 32 . Last week he went to Mount Emei in Sichuan with his 33    .
Many people like to travel by 34 , but the Greens think that travelling by train is the best. It is much 35 and far more enjoyable than a rushed journey by air. They had a won­derful train ride to Chengdu 36  they went on to Mount Emei by bus.
The train was quite nice and tidy, and there weren’t too many people in 37  sleeping car. The Greens could stand up and 38 around. It was a long journey, 39  none of them felt tired. They kept 40  the beautiful things out of the window. They talked, laughed and played cards. The conductor kept coming to give them hot water and 41  them newspapers. People nearby 42 with each other. A young man tried to speak English with Mr and Mrs Green. Jim thought the train was like a big moving party. He went to sleep quite 43 . He enjoyed listening to the sound of the running train and then fell asleep.
When Jim woke up the next morning, the train was already 44 Chengdu. His train ride seemed really 45 , but his memory (記憶) of the pleasant journey will last long.

The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution.

To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, drink it and even eat it. Pollution is beginning to threaten (威脅) our health, our happiness and our life.

Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another place. At first, the problem was not so serious because there was plenty of clean air, land and water. There weren’t so many people then and their wants fewer. All the dirty things could be absorbed(吸收) by nature and soon covered over. But this is no longer true. The increase of pollution and the development of industry(工業(yè)) have changed that. Man is slowly poisoning(毒害)not only his environment but also himself.

Through the use of poison, man has polluted the land, killing the animals. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water, killing the fish.

Our increasing population is part of the problem. More people, more waste.

Where is this all to end? Are we turning the world into a big rubbish dump(堆存處)，or is there any hope that we can get rid of (擺脫，除去) the pollution? Luckily, millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under control.

The earth is our home. We must take care of it. This means keeping the land, air and water clean. And we must take care of the rise in pollution at the same time.
