The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago; but it has brought new problems. One of the biggest is pollution. To pollute mean to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.

Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men 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 to all living things in the world, but it is not only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us become angry more easily.

Many countries are making rules to fight pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.

 The pollution of SO₂ is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is 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 keep careful of the rise in pollution at the same time.

【小题1】_______, our world is becoming much smaller.

Is it wrong to use someone else’s wireless (Wi-Fi) connection? Just recently, a man was arrested for doing just that. At that time, he was sitting in the street with a laptop(便携式电脑) and using an unsecured(无安全保护措施) wireless connection to surf the Net. What do you think about this topic? Listen to the following different views on it.

For a start, if someone is using your Internet service or downloading, this will affect your speed of access or download limit. Also, it’s bad for Internet service providers. They will suffer in the long run because fewer people will pay for an Internet service if they know they can get it for free. And finally, just imagine this: what if the person who is stealing your Internet connection is involved in an illegal activity? I think the police are totally right to arrest these criminals.

— by Sandra Wilkins

Basically, if the person who paid for the service still has everything they paid for, what’s the problem? It’s just like using the light from streetlamps to read your book, or watching someone else’s firework display. It’s not stealing.

Also, if you leave your wireless connection unsecured, then it is your own fault(过错) if someone else uses it. Just as you wouldn’t leave your front door unlocked, or your car door open, neither should you leave your wireless connection open. By leaving your wireless connection open, you are inviting people to use it. Securing your wireless connection is as easy as clicking a few settings on your router(路由器). And finally, haven’t the police got more important crimes to solve? They’re always saying how they haven’t got the manpower to solve real issues. But this is just ridiculous(荒谬的).
