As Internet users become more dependent on the Internet to store information， are people remember 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 remember the folder location （位置） 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 organize 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.

need to have a mobile phone by our side？

We could start with the advantages of mobile phones. There are many things that we could do with mobile phones. With the advancement of technology，more and more features are being added to the mobile phones which make them more useful. In addition to making calls，mobile phones also support a wide variety of other services such as text messaging，email，Internet access，business applications，gaming and photography. We can bring them everywhere，and can be reached by others anytime. They make the world smaller，bringing people together no matter where they are.

But we could have some risks when using our mobile phones. We may have accidents when we use them while driving. Some studies show that mobile phones can do harm to our bodies;and materials in mobile phones could damage our environment.

Since there are so many risks，why do we still have mobile phones？This is because these risks or disadvantages can be overcome. For example，while we are driving we can easily pull up our car if we really need to use the phone. Mobile phone manufacturers are reducing the radiation of mobile phones to avoid health risks.

Though there are both pros and cons of using mobile phones，we could easily see that there are more advantages than disadvantages. Moreover，mobile phones are becoming cheaper，which might be another reason why mobile phones are increasingly used today.

1. Which of the following functions is NOT mentioned in the passage？

A. Text messaging.

B. Camera.

C. GPS.

2. What risks might mobile phones cause？

A. Traffic accidents and health problems.

B. Environmental damage.

C. Both A and B.

3. What are mobile phone manufacturers doing to prevent mobile phone users from health risks？

A. They are reducing the radiation of mobile phones.

B. They are trying to persuade people to use mobile phones less.

C. They are developing new models of mobile phones.

4. Why do people still use mobile phones despite their disadvantages？

A. Because people don’t believe that mobile phones have any disadvantages.

B. Because the disadvantages of mobile phones can be avoided.

C. Because people cannot live without mobile phones.

5. According to the last paragraph，why are mobile phones increasingly being used today？

A. They are safer.

B. They have more functions.

C. They are becoming cheaper.

听力原文：M: So, what do you want to do tomorrow？

W: Well, let's look at this city guide here. Uh, here's something interesting. Oh! Why don't we first visit the art museum in the morning.

M: Okay. I like that idea. And where do you want to eat lunch？

W: How about going to an Indian restaurant？ Humm. The guide recommends one downtown a few blocks from the museum.

M: Now that sounds great. After that, what do you think about visiting the zoo？ Umm, well, it says here that there are some very unique animals not found anywhere else.

W: Well, to tell the truth, I'm not really interested in going there. Why don't we go shopping instead？ There are supposed to be some really nice places to pick up souvenirs.

M: Nail, I don't think that's a good idea. We only have few traveler's checks left, and I only have fifty dollars left in cash.

W: No problem. We can use your credit card to pay for MY new clothes.

M: Oh, no. I remember the last time you used my credit card for your purchases.

W: oh well. Let's take the Subway down to the seashore and walk along the beach,

M: Now that sounds like a wonderful plan.

hat social change exists everywhere. Technology, the application of knowledge for practical ends, is a major source of social change.

Yet we would do well to remind ourselves that technology is human creation; it does not exist naturally. A spear or a robot is as much a cultural as a physical object. Until humans use a spear to hunt game or a robot to produce machine parts, neither is much more than a solid mass of matter. For a bird looking for an object on which to rest, a spear or robot serves the purpose equally well. The explosion of the Challenger space shuttle and the Russian nuclear accident at Chemobyl drive home the human quality of technology; they provide cases in which well-planned systems suddenly went haywire and there was no ready hand to set them right. Since technology is a human creation, we are responsible for what is done with it. Pessimists worry that we will use our technology eventually to blow our world and ourselves to pieces. But they have been saying this for decades, and so far we have managed to survive and even flourish. Whether we will continue to do so in the years ahead remains uncertain. Clearly, the impact of technology on oar lives deserves a closer examination.

Few technological developments have had a greater impact on our lives than the computer revolution. Scientists and engineers have designed specialized machines that can do the tasks that once only people could do. There are those who assert that the switch to an information-based economy is in the same camp as other great historical milestones, particularly the Industrial Revolution. Yet when we ask why the Industrial Revolution was a revolution, we find that it was not the machines. The primary reason why it was revolutionary is that it led to great social change. It gave rise to mass production and, through mass production, to a society in which wealth was not confined to the few.

In somewhat similar fashion, computers promise to revolutionize the structure of American life particularly as they free the human mind and open new possibilities in knowledge and communication. The Industrial Revolution supplemented and replaced the muscles of humans and animals by mechanical methods. The computer extends this development to supplement and replace some aspects of the mind of human beings by electronic methods. It is the capacity of the computer for solving problems and making decisions that represents its greatest potential and that poses the greatest difficulties in predicting the impact on society.

A spear or a robot has the quality of technology only when it ______.

A．can be of use to both man and animal

B．is utilized by man

C．serves different purposes equally well

D．is used both as a cultural and a physical object
