Today there are about seven million Americans in the colleges and universities. Young persons under twenty-five make up nearly half of the American population. Many of these will soon be in charge of the nation. Naturally, their ideas are important to everyone in the country, and it is necessary for older people to understand what they think and feel.
College students today have strong opinions about right and wrong. They are deeply interested in making a better life for all people, especially for those who have not been given a fair chance before now. They see much that is wrong in the lives of their parents. It is hard for them to see what is right and good in the older ways. As a result, there is often trouble in American families.
Which of the following statements is true？
A．People haven't written much about American youth.
B．Writers have wasted a great deal of their effort(努力)to write about American youth.
C．Much has been written about American youth.
D．Young people's ideas are not important enough to the United States.

听力原文： Millions of words have been written about young people in the United States. There are reasons for this great interest in the ideas, feelings, and actions of youth.
[32] Today there are about seven million Americans in colleges and universities. [33] Young persons under twenty-five make up nearly half of the American population. [34] Many of these will soon be in charge of the nation. Naturally their ideas are important to everyone in the country, and it is necessary for older people to understand what they think and feel.
College students today have strong opinions about right and wrong. [35] They are deeply interested in making a better life for all people, especially for those who have not been given a fair chance before now. They see much that is wrong in the lives of their parents. It is hard for them to see what is right and good in the older way. As a result, there is often trouble in American families. Your country may be meeting such problems, too.

A．About seven million.
B．Nearly half of the American population.
C．25% of American people.
D．We don't know exactly from the passage.

听力原文： First aid is the initial care of a suddenly sick or injured person. It is the care administered by a person as soon as possible after an accident or illness. It is this prompt care and attention prior to the arrival of the ambulance that sometimes means the difference between life and death, or between a full or partial recovery.
The main aims of first aid are:
To preserve life;
To protect the casualty from further harm;
To relieve pain.
As in most endeavors, the principle to be adopted in first aid is immediate action. Bystanders or relatives not knowing what to do may have unwittingly contributed to unnecessary deaths and chronic injuries. If a person is sick or injured, then he needs help immediately.
Quick action is necessary to preserve life. A casualty who is not breathing effectively, or is bleeding heavily, requires immediate assistance. If quick effective first aid is provided, then the casualty has a much better chance of a good recovery.
It is important that quick action does not lead to panic. Careful and deliberate action undertaken without too much delay is most beneficial to the casualty. Try to remain calm and think your actions through. A calm and controlled first aider will give everyone confidence that the event is being handled efficiently and effectively.
Despite differences between emergencies, you can make it work if you follow the principles of first aid even if you are not sure of what the underlying problem is.
(23)
A．After the victim is sent to hospital.
B．After the causes of the victim's suffering becomes clear.
C．After the arrival of the ambulance.
D．As soon as possible after the accident or illness.

听力原文： Carly Fiorina was the first chief executive chosen from outside to make changes at the technology company, Hewlett-Packard. Fortune magazine named her "the most powerful woman in business".
Soon after she arrived at H-P, a lot of people thought (29) she meant that women and minorities face no barriers to rising in companies. A research group found that women held sixteen percent of top jobs at the largest American companies in 2002. Many chief executives keep their jobs just three or four years. Miz Fiorina stayed almost six. Some people say Carly Fiorina received the same treatment that a man would have received. (30) Critics said she kept too much power to herself. They said her actions harmed financial performance. H-P stock now sells for less than half its price when she arrived. In 2001 she announced a deal to combine Hewlett-Packard with Compaq Computer. Some shareholders resisted. Walter Hewlett, the son of one of the two men who started H-P, opposed the deal in court. But shareholders approved it in March of 2002. (31) Results have been mixed. Since the merger with Compaq, H-P has increased its share of the world computer market to almost sixteen percent. But Dell has grown faster. That company now holds almost twenty percent of the highly competitive market. (31)Still, H-P remains the leading maker of computer printers in the world. And it is now the eleventh largest company in the United States.

A．She pulled the company through extreme difficulties.
B．She earned a lot of profits for the company.
C．She proved that women are admitted into the largest companies.
D．She proved to be the most qualified chief executive.

Controlling Robots with the Mind
Belle, our tiny monkey, was seated in her special chair inside a chamber at our Duke University lab. Her right hand grasped a joystick (操纵杆) as she watched a horizontal series of lights on a display panel. She knew that if a light suddenly shone and she moved the joystick left or right to correspond to its position, she would be sent a drop of fruit juice into her mouth.
Belle wore a cap glued to her head. Under it were four plastic connectors, which fed arrays of microwires-each wire finer than the finest sewing thread- into different regions of Belle's motor cortex (脑皮层), tile brain tissue that plans movements and sends instructions. Each of the 100 microwires lay beside a single motor neuron (神经元). When a neuron produced an electrical discharge, the adjacent microwire would capture the current and send it up through a small wiring bundle that ran from Belle's cap to a box of electronics on a table next to the booth. The box, in turn, was linked to two computers, one next door and the other half a country away.
After months of hard work, we were about to test the idea that we could reliably
translate the raw electrical activity in a living being's brain-Belle's mere thoughts-into signals that could direct the actions of a robot. We had assembled a multi-jointed robot arm in this room, away from Belle's view, which she would control for the first time. As soon as Belle's brain sensed a lit spot on the panel, electronics in the box running two real-time mathematical models would rapidly analyze the tiny action potentials produced by her brain cells. Our lab computer would convert the electrical patterns into instructions that would direct the robot arm. Six hundred miles north, in Cambridge, Mass, a different computer would produce the same actions in another robot arm built by Mandayam A. Srinivasan. If we had done everything correctly, the two robot arms would behave as Belle's arm did, at exactly the same time.
Finally the moment came. We randomly switched on lights in front of Belle, and she immediately moved her joystick back and forth to correspond to them. Our robot arm moved similarly to Belle's real arm. So did Sriniwlsan's. Belle and the robots moved in synchrony (同步), like dancers choreographed (设计舞蹈动作) by the electrical impulses sparking in Belle's mind.
In the two years since that day, our labs and several others have advanced neuroscience, computer science and microelectronics to create ways for rats, monkeys and eventually humans to control mechanical and electronic machines purely by "thinking through," or imagining, the motions. Our immediate goal is to help a person who has been unable to move by a neurological (神经的) disorder or spinal cord (脊髓) injury, but whose motor codex is spared, to operate a wheelchair or a robotic limb.
Belle would be fed some fruit juice if she
A．grasped the joystick.
B．moved the joystick to the side of the light.
C．sat quietly in a special chair.
D．watched lights on a display panel.
