Pollution

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine, either.

Life today has brought new problems. One of the biggest is pollution (污染). Water pollution has made our rivers and lakes dirty. It kills our fish and polluted our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.

Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog(烟雾).

Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, they mustn’t blow dirty smoke into the air.

We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.

Rules are not enough. Every person must help to fight pollution.

The Most Useful Inventions

The Most Useful Invention of All Time?

Barbara-Saturday, April 13

I’m writing a paper for my English class, and I need some ideas. What do you think is the most useful invention of all time? Thanks for your thoughts.

RE: The Most Useful Invention of All Time?

Cindy Wu-Saturday, April 13

There are many-the phone, the car, the bridges, but these are not my choices. For an everyday, useful invention, I vote() for the air conditioner. I live in Hong Kong, and during the summer, the temperature reaches 35 degrees Celsius or more. The heat is terrible! Without air conditioning, people here can not work or study. A lot of people might also get sick without cool air.

RE: The Most Useful Invention: The Internet!

Jorge-Sunday, April 14

The most useful invention of all time is the Internet . We can now communicate with people and do business faster. I own a clothing store in Mexico City. I also have a website. Now, people from all over the world can buy my clothing using my web site. I can keep in touch with friends and family in Mexico and around the world using e-mail. It’s faster than regular mail, and it’s cheaper than using the phone!

RE: The Most Useful Invention: Yes, but…

Kazuo-Monday, April 15

Jorge, I agree-the Internet is useful. But, in my opinion, there is an invention that is the most useful -electricity. Of course, this isn’t a man-made invention, but people like Benjamin Franklin and Alessandro Volta learned how to use it. Without electricity, many of the world’s most important inventions would not work.

Do you go to school by bus? It is very important for you to know how to be safe when taking a bus, no matter whether you like it or not.

First, don’t run to the bus stop, but walk. While you are at the bus stop, you should wait in a safe place. Do not run or play while waiting. And never get into a car with a stranger.

Second, don’t talk in a loud voice when you are on the bus, so the driver will not be disturbed(打扰). If you need to talk with the bus driver, you’d better wait until the bus stop. Never throw things on the bus or out of the windows. Never play near the emergency exit(紧急出口). When there is a fire, the most important thing is to break the window with a hammer or any sharp things and then jump out.

Third, when you are getting off the bus, make sure you walk(not run) three more steps away from the door. This is the best place to be around a bus. Stay away from the bus wheels and watch out for moving cars!

Last, if you leave something on the bus, never return to the bus to get it. The driver may not see you come back and he may begin moving the bus. Also, if you drop something near the bus, tell the driver before you try to pick it up, so he will know where you are.
