Teens don’t understand the big fuss. As the first generation to grow up in a wired world, they hardly know a time when computers weren’t around, and they eagerly catch the chance to spend hours online, chatting with friends. So what?

But researchers nationwide are increasingly worried that teens are becoming isolated, less skillful at person-to-person relationships, and perhaps numb to the cheatings that are so much a part of the e-mail world. “and a teen’s sense of self and values may be changed in a world where personal connections can be limitless,” said Sherry Turkle.

Another researcher, Robert Kraut, said he’s worried about the “opportunity costs” of so much online time for youths. He found that teens who used computers, even just a few hours a week, showed increased signs of loneliness and social isolation. “Chatting onine may be better than watching television, but it’s worse than hanging out with real friends,” he said.

Today’s teens, however, don’t see anything strange in the fact that the computer takes up a central place in their social lives, “School is busy and full of pressure. There’s almost no time to just hang out.” said Parker Rice, 17. “Talking online is just catch up time.”

Teens say they feel good about what they say online or taking the time to think about a reply. Some teens admit that asking someone for a date, or breaking up, can be easier in message form, though they don’t want to do so. But they insist there’s no harm.

She researchers argue that___．

A．teens may develop a different sense of values

B．nothing is wrong with teens' chatting online

C．teens can manage their social connections

D．spending hours online does much good to teens

Teens think that talking online can help them ____．

A．use computers properly B．improve their school work

C．develop an interest in social skills D．reduce their mental pressures

The text mainly deals with __ _．

A．teens' pleasant online experience

B．teens' computer skills and school work

C．the effects of the computer world on teens

D．different opinions on teens' chatting online

The purpose of the text is to ____．

A．describe computer research results

B．draw attention to teens' computer habits

C．suggest ways to deal with problem teens

D．discuss problems teens have

Since the 1970s, scientists have been searching for ways to link the brain with computers．Brain-computer interface（BCI） technology could help people with disabilities send commands to machines．
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated（展示）a small robotic wheelchair directed by a person’s thoughts．
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand．He could even talk as he watched the vehicle and guided it with his thoughts．
“Our brain has billions of nerve cells．These send signals through the spinal cord（脊髓）to the muscles to give us the ability to move．But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says．“Our system allows disabled people to communicate with external world and also to control devices．”
The researchers designed a special cap for the user．This head cover picks up the signals from the scalp（头皮）and sends them to a computer．The computer interprets the signals and commands the motorized wheelchair． The wheelchair also has two cameras that identify objects in its path．They help the computer react to commands from the brain．
Prof．Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands．“The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices．One example is this wheelchair．”
He says his team has set two goals．One is testing with real patients, so as to prove that this is a technology they can benefit from．And the other is to guarantee that they can use the technology over long periods of time．
【小题1】BCI is a technology that can .

A．help to update computer systems	B．link the human brain with computers
C．help the disabled to recover	D．control a person's thoughts

【小题2】How did Tavella operate the wheelchair in the laboratory?

A．By controlling his muscles．	B．By talking to the machine．
C．By moving his hand．	D．By using his mind．

【小题3】The team will test with real patients to .

A．make profits from them	B．prove the technology useful to them
C．make them live longer	D．learn about their physical condition

【小题4】Which of the following would be the best title for the text?

A．Switzerland, the BCI Research Center

B．New Findings About How the Human Brain Works

C．BCI Could Mean More Freedom for the Disabled

D．Robotic Vehicles Could Help to Cure Brain Injuries

Some disabled people use a special card when they park their cars. These are called disabled placards, which are removable signs that can be hung from the rear-view(后视) mirror of a car. These placards are only supposed to be for disabled people.

These placards are meant to help disabled people in a number of ways. They allow the person to park in special parking spaces. They can also be used when disabled people are being dropped off or picked up. Disabled people can even use them to park without having to pay.

Parking officials think that some people are cheating. Not all people who have these placards are disabled. Today, one in sixteen drivers in California carries the sign. There are a lot more people who have disabled placards today than ten years ago. An official from the DMV(加州车辆管理局) says that there are many reasons for the increase. As people get older, they may develop health problems and need to have one. There are also other reasons why more drivers have them today. Finally, there are a number of people who have them that should not.

Last year the DMV cancelled more than 25,000 permits. They found that lots of people who had the disabled placards had died. These permits are no longer valid.

Some people are worried that the system is being abused. They are worried that access to the program could be limited because of the misuse. More rules could make it harder for people with real disabilities to get these placards.

A. The reasons why disabled placards are also popular among drivers.
