The world itself is becoming much smaller by using modern traffic and modern communication means (通讯设备).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 means 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 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 carbon dioxide is now the most dangerous kind of air pollution. It is caused by heavy traffic. It is true 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 population at the same time.

Pets are popular. They’re good listeners, they encourage us to exercise, and they’re always on our side when we argue with others. They can bring people comfort and pleasure.

But it is important to keep in mind that pets can carry diseases that can make you sick. Washing your hands often — especially after you touch, feed, or clean up a pet — is the best way to keep yourself healthy and prevent the spread of disease. Be sure to clean your fingernails(指甲)carefully every time you wash.

You also can protect your health by wearing gloves while cleaning animal cages or cat litter boxes. Avoid washing your pet in the bathtub (浴缸), but if you do, always disinfect (消毒) the tub immediately afterward.

Be sure to bring your pet to the hospital for examinations every two weeks or month and whenever your pet is sick or injured.

You can do a few other things to keep yourself and your pet healthy. Only give your pet food that has been planned ahead for them. It’s not a good idea to share your food with your pet. Human food (like chocolate) can make animals sick. Never feed your pet raw meat because it can carry germs (细菌) that cause serious illness.

And funny as it can be to see your dog or cat drinking from the toilet, don’t let pets do this. It’s bad for your pet’s health! Give them clean, fresh water to drink at all times.

Never give milk to cats. The only milk an animal should drink is from its mother. Cow’s milk is not for pets, especially for cats, as it makes them sick.

Finally, some animals aren’t pets. Don’t take in a wild or abandoned (被抛弃的) animal as a pet because it may have diseases that could make you or your family sick. Instead, turn to an animal rescue group that is trained in helping sick or abandoned animals.
