1 . As Internet users become more dependent on the Internet to store information, are people remembering less? If you know your computer will save information, why store it in your own personal memory,your brain? Experts are wondering if the Internet is changing what we remember and how.

In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.

In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remembered the folder location better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called “transactive memory (交互记忆)”.

According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organise huge quantities of information so that they are able to access it at a later date. This doesn’t mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

We all know that cycling is a greatly exercise. A doctor tells me people who lives the longest are dancers and cyclists. Maybe it is because the combination of fresh air, smooth movement and exercise. Whether you ride a bicycle, you don’t use petrol. So they are not producing carbon dioxide and not cause air pollution. Just see how cars have been taken over our cities. They often run at high speeds, what may put our lives in danger. And there were traffic jams, too. Our cities will be better places if we replace cars with bicycle.

As is known by all，the Internet is playing a more and more important part on our daily life. On the Internet, we can not only read news at home or abroad but also get much information as possible. For an example, we often send e­mails and make telephone call to our families and friends. What's more, they can go to school on the Internet，read different kinds of books and even teaches ourselves English. We can also listen to music, watching sports and play computer games. We can even do shopping without left our houses.
