阅读下面短文并回答问题，然后将答案写到答题卡相应的位置上(请注意问题后的词数要求)。
[ 1 ] Do you spend over an hour each day texting messages to your friends? Do you frequently ignore work, study, and other activities to check your phone for messages? Are you anxious and restless if you are separated from your mobile phone,9 Do you hardly ever use your phone to talk any more, and do your thumbs hurt from texting too much?
[2] If , then it is very possible that you are a textaholic. A textaholic can be defined as someone who is addicted to sending and receiving messages. The main symptoms are a strong desire to text messages, which takes precedence (优先)over everything else, and bad moods, low spirits and a lack of self-confidence if messages fail to come in. The root of the problem, as with many addictions, is the desire to escape from emotional difficulties such as stress, atrxiety and relationship problems. Experts warn that text addiction is likely to become the most common form of addiction in the future, especially among the young.
[3] So what can you do if you think you may be a textaholic? The key is to get your life back in balance. Make sure you resist the urge to answer every message you receive, and consider leaving your mobile phone behind occasionally when you go out. Most importantly, make a point of spending quality time with friends and family, and make time to re-learn the art of face-to-face conversation instead of conducting your relationships by means of text messages. Not only will you save time and money, but you may also rediscover the pleasure of true communication.

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 band. He could even talk as he watched the vehicle and guided it with his thoughts.
“our brain has billions of nerve ceils. 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 frotn. And the other is to guarantee that they can use the technology over long periods of time.
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
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.
3.
Which of the following shows the path of the signals described in Paragraph 5?
A. scalp→computer→cap→wheelchair
B. computer→cap→scalp→wheelchair
C. scalp→cap→computer→wheelchair
D. cap→computer→scalp→wheelchair
4.
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
5.
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
Diana Jacobs thought her family had a workable plan to pay for college for her 21-year-old twin sons: a combination of savings, income, scholarships, and a modest amount of borrowing. Then her husband lost his job, and the plan fell apart.
“I have two kids in college, and I want to say ‘come home,’ but at the same time I want to provide them with a good education,” says Jacobs.
The Jacobs family did work out a solution: They asked and received more aid form the schools, and each son increased his borrowing to the maximum amount through the federal loan (贷款) program. They will each graduate with $20,000 of debt, but at least they will be able to finish school.
With unemployment rising, financial aid administrators expect to hear more families like the Jacobs. More students are applying for aid, and more families expect to need student loans. College administrators are concerned that they will not have enough aid money to go around.
At the same time, tuition（学费）continues to rise. A report from the National Center for Public Policy and Higher Education found that college tuition and fees increased 439% from 1982 to 2007, while average family income rose just 147%. Student borrowing has more than doubled in the last decade,
“If we go on this way for another 25years, we won’t have an affordable system of higher education,” says Patrick M. Callan, president of the center. “The middle class families have been financing it through debt. They will send kids to college whatever it takes, even if that means a huge amount of debt.”
Financial aid administrators have been having a hard time as many companies decide that student loans are not profitable enough and have stopped making them. The good news, however, is that federal loans account for about three quarters of student borrowing, and the government says that money will flow uninterrupted.
