New Lives for Old Phones

When a new mobile phone starts to be sold in stores, many people rush out to buy one. We all want the newest, latest thing.1.

Mike Townsend works at Total Recall, a mobile phone recycling company. "Don't throw your old phone away. 2.If you throw it away, it goes with other rubbish to become landfill. In other words, it is put in a big hole in the ground-and it becomes a big problem," he says.

Mobile phones contain some poisonous materials. If your phone goes to a landfill, these poisonous materials can get out and get into the water under the ground. That's the water we need to drink or water goes into rivers or the ocean. 3. That's a lot of landfill and a lot of poisonous materials.

"At Total Recall, we separate the old phones into pieces. Most of the materials in the mobile phones can be recycled and used again.4. For example, phone batteries contain nickel and cadmium. The nickel is used to make steel, and the cadmium can be used to make new batteries," explains Mike.

"5.You can usually just take it into a mobile phone shop and they will send it to us," says Mike.

So before you throw that old mobile phone away, use it one last time: search for a recycler near you and give them a call.

A. Send it to us and we'll recycle it.

B. Recycling your old phone is easy.

C. How much is your old mobile phone worth?

D. But what should we do with our old mobile phones?

E. Millions of mobile phones are thrown away every year.

F. We take apart the old phones and they are used to make new products.

G. Recycling materials helps keep the environment greener and cleaner.

As more people use smart phones to pay bills and store personal information, strict password security has become more important than ever. A new study shows that free-form gestures–sweeping fingers in shapes across the screen of a smart phone—can be used to unlock phones. These gestures are less likely to be observed and reproduced by others than traditional typed passwords.

“All that it takes to steal a password is a quick eye,” said one of the researchers of the study. “With all the personal information we have on our phones today, improving their security is becoming increasingly necessary.” In developing a secure solution to this problem, the researchers studied the practicality of using free-form gestures. With the ability to create any shape in any size and location on the screen, the gestures were popular as passwords. Since users create them without following a template, the researchers predicted these gestures would allow for greater complexity.

The researchers carried out a create-test-retest experiment where 63 people were asked to create a gesture, recall it, and recall it again 10 days later. The gestures were captured on a recognizer system designed by the team. Using this data, they tested the complexity and accuracy of each gesture using information theory. The result of their analysis is that people are favorable to use free-form gestures as passwords.

To put their analysis into practice, the researchers then had seven students in computer science and engineering, each with considerable experience with touchscreens（触摸屏）, attempt to steal a free-form gesture password by observing a phone user secretly. None of them were able to copy the gestures with enough accuracy. The gestures appear to be extremely powerful against attacks.

Though the testing is in its early stage and widespread adaptation of this technology is not yet clear, the research team plans to continue to analyze the security and management of free–form passwords in the future. They believe this is the first study to explore free-form gestures as passwords. They will soon publish their findings.

1.What can we learn about free-form gestures?

A. They are improving mobile security in a way.

B. Users will have to make use of simple gestures.

C. They will never be copied by others.

D. Users must move their fingers in fixed shapes.

2.The experiment in paragraph 4 is to test _________ of free - form gestures.

A. template            B. application            C. accuracy            D. security

3.According to the text, the researchers think that ________.

A. it is easy to steal any password with a quick eye

B. better ways of setting passwords should be developed

C. people had better not use smart phones to pay bills

D. personal information should not be stored in a phone

4.The main purpose of the text is to ________.

A. advise people to use free-form gestures

B. discuss whether smart phones are safe

C. talk about the practicality of passwords

D. introduce the study of a new password

Across the world, mobile phones are very popular with young people. They think that the phones are more than a means of communication — having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has worried some health professionals. Some doctors are concerned that in the future many people will suffer from health problems because of the use of mobile phones. But mobile phone companies say that there is no proof that mobile phones are bad for health.

On the other hand, why do some medical studies show changes in the brain cells of some people who use mobile phones? Signs of change in the tissue (组织) of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at a young age due to the fact that he couldn’t remember even simple tasks. The man had been talking on his mobile phone for about six hours a day for a couple of years. His family doctor blamed his mobile phone use.

What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about their safety continues, it appears that it is better to use mobile phones less often. Use a normal phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. So, for now, it is wise not to use your mobile phone too often.

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 how 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.

1.What can we learn about the first experiment?

A. Sparrow's team typed the information into a computer.

B. The first group didn’t know where the information is.

C. The two groups remembered the information equally well.

D. The second group had a better memory of the information.

2.In transactive memory, people ______.

A. know how to access huge amounts of information later.

B. learn how to organize small amounts of information.

C. organize huge quantities of information like a computer.

D. bear huge quantities of information in mind.

3.What is the effect of the Internet according to Sparrow's research?

A. We are becoming more intelligent.

B. We are using memory differently.

C. We have poorer memories than before.

D. We need a better way to access information.
