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 dirty. Pollution comes in many ways. We see it, smell it, drink it and even eat it.

   Man has been polluting the earth. The more people, the more pollution. Many years ago, the problems was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.

   Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.

   Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollutions. It is caused by heavy traffic. We are sure that if there are fewer people driving there will be less air pollution.

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

What’s your idea about success? Some people say that beginners have all the luck, while others believe that success    1 only with practice. In fact, I feel both of these statements (陈述) are not true all the time. Each is true in some ways    2   not in others.
For example, I went to a drawing competition many years ago and   3   surprisingly. As a prize, I got a film ticket to see “Titanic”. I was really   4  because it was the first time I had taken part in any competition, Thinking that I might be lucky again, I  5  joining in other art competitions, But the result was that I   6  won again. I accepted the fact that the other people had a  7  artistic ability than I did. Art was not something I was especially interested in and I had never practiced the different art skills. So, the  8 I produced were not of a very high standard(水平).
These experiences taught me a lot. Though I might have been lucky  9 , I also need to put in hard work. As we know,  10 makes perfect. So I believe success builds on less luck and chance.
