What do you think are the most important inventions of the past 2,000 years? The TV? The printing? The telephone? Or the computer? A report shows that these are not the only important inventions. Here are four other important ones.

Paper is one of the most important inventions. You can’t have printing without paper. In 105 AD, Cai Lun invented paper in China. Long before the printing and Internet, Cai Lun’s invention allowed us to write down information, stories and history.

One of the simplest (最简单) inventions to save life is the toilet. Before toilets, waste ran into the rivers from people’s houses. Illnesses were common (普通的) in big cities, and it was often difficult to find clean drinking water.

Animal food is another invention. Before the invention, most animals were killed every autumn because there was not enough food for them in the winter. After hay (干草) became a kind of common animal food, animals could live through the long winter.

Reading glasses is the fourth invention. People start getting far-sighted (远视) from the age of 45. Glasses mean that anyone can read, write and do “close work” after that age. Without glasses, the world would be difficult for the people above 45.

Today’s question is:

　　　 What do you think is the most useful invention of all time?

Posted by Cindy Wu on Saturday, April 13

There are many ---the train , the car, the airplane are useful machines, but these are not my choices. For an everyday, useful invention, I vote for the air conditioner. I live in Taibei, and during the summer the temperature can be 35degrees Celsius（摄氏度)or more. It’s so hot! I’m not joking when I say that, without an air conditioner, people here cannot work or study. A lot of people might also get sick without cool air.

The most useful invention of all time is surely the Internet. We can now reach people and do business faster. I own a clothing store in Mexico City, and there is a lot of competition(竞争). I also have a website. Now, people from all over the world can buy my clothing using my website. I can keep in touch with friends and family in Mexico and around the world using e-mail. It’s faster than usual mail, and it’s cheaper than using the phone.
