听力原文： Many of us believe that a person's mind becomes less active as he grows older. But this is not true, according to Dr. Lissy F. Javik, professor of psychiatry at the University of California, Los Angeles. Dr. Jarvik has studied the mental functioning of aging persons for several years. For example, one of her studies concerns 136 pairs of identical twins, who were first examined when they were already 60 years old. As Dr. Jarvik's continued the study of the twins into their 70s and 8Os, their minds did not generally decline as was expected.
However, there was some decline in their psychomotor speed. This means that it took them longer to accomplish mental tasks than it used to. But when speed was not a factor, they last very little intellectual ability over the years. In general, Dr. Jarvik's studies have shown that there is no decline in knowledge or reasoning ability. This is true not only into the 30s and 40s but also into 60s and 70s as well.
As for learning new things, and ability to remember, studies by Dr. Jarvik and others show that the old are equal to the young. It is true that older people themselves often complain that their memory is not as good as it once was. However, much of what we call "loss of memory" is not that at all. There usually was incomplete learning in the first place. For example, the older person perhaps had trouble hearing or poor vision, or inattention, or was trying to learn the new thing at a speed that was too fast.
In the cases where the older person's mind really seems to decay, it is not necessarily a sign of a decay due to old age or "senility". Often it is simply a sign of a depressed emotional state. The depression usually can be counteracted by counseling, therapy with a psychologist, or medications which fight depression.

Today I've returned to Chicago to discuss another issue relating to our security, and that's the need for us to improve the health security of American citizens.
And for the sake of health care for all Americans, we must reform. the medical liability system. For years, leaders of both political parties have talked about these reforms. Now is the time to get the job done.
We have just had a discussion with fellow citizens--some doctors and other professionals on medical care. I want to thank them for joining me today and sharing their stories and their concerns about the future of health care in our country.
One thing is for certain about health care in our country, that is, we've got the best health care system in the world, and we need to keep it that way. We've got great doctors in America. We're really good at research. We're developing technologies and medicines which are extending lives not only in our country, but also across the world.
To make sure we've got a good health care system today and tomorrow, we've got to make sure that no policy of the federal government will undermine (损坏) the system of private care in America. As folks who deliver that care, you know that we've got challenges in our system. We must address the challenges while not undermining the strengths of American medicine.
We have got a problem in America that we must deal with. Medical liability is not only a local problem, but a national issue that requires a national solution.
There are challenges in the health care system. We understand that in Washington. And we can answer those challenges with practical, sensible, compassionate (有同情心的) reforms. That is the charge before us, and that is the charge we must keep on behalf of the American people.
What is the problem being talked about for years in America？
A．Leaders of political parties.
B．Reforms of social security.
C．Security of American citizens.
D．Improvement of the health security.
Trust Me, I'm a Robot
With robots now emerging from their industrial cages and moving into homes and workplaces, roboticists are concerned about the safety implications beyond the factory floor. To address these concerns, leading robot experts have come together to try to find ways to prevent robots from harming people. Inspired by the Pugwash Conferences—an international group of. scientists, academics and activists founded in 1957 to campaign for the non-proliferation of nuclear weapons—the new group of robo-ethicists met earlier this year in Genoa, Italy, and announced their initial findings in March at the European Robotics Symposium in Palermo, Sicily.
"Security and safety are the big concerns," says Henrik Christensen, chairman of the European Robotics Network at the Swedish Royal Institute of Technology in Stockholm. Should robots that are strong enough or heavy enough to crush people be allowed into homes？ Is "system malfunction" a justifiable defence for a robotic fighter plane that contravenes(违反) the Geneva Convention and mistakenly fires on innocent civilians？
These questions may seem hard to understand but in the next few years they will become increasingly relevant, says Dr. Christensen. According to the United Nations Economic Commission for Europe's World Robotics' Survey, in 2002 the number of domestic and service robots more than tripled, nearly surpassing their industrial counterparts. By the end of 2003 there were more than 600,000 robot vacuum cleaners and lawn mowers—a figure predicted to rise to more than 4m by the end of next year. Japanese industrial firms are racing to build humanoid robots to act as domestic helpers for the elderly, and South Korea has set a goal that 100% of households should have domestic robots by 2020. In light of all this, it is crucial that we start to think about safety guidelines now, says Dr. Christensen.
Stop right there
So what exactly is being done to protect us from these mechanical menaces？ "Not enough," says Blay Whitby. This is hardly surprising given that the field of "safety-critical computing" is barely a decade old, he says. But things are changing, and researchers are increasingly taking an interest in trying to make robots safer. One approach, which sounds simple enough, is try to program them to avoid contact with people altogether. But this is much harder than it sounds. Getting a robot to navigate across a cluttered room is difficult enough without having to take into account what its various limbs or appendages might bump into along the way.
Regulating the behaviour of robots is going to become more difficult in the future, since they will increasingly have self-learning mechanisms built into them, says Giamnarco Veruggio. As a result, their behaviour will become impossible to predict fully, he says, since they will not be behaving in predefined ways but will learn new behaviour as they go.
Then there is the question of unpredictable failures. What happens if a robot's motors stop working, or it suffers a system failure just as it is performing heart surgery or handing you a cup of hot coffee？ You can, of course, build in redundancy by adding backup systems, says Hirochika Inoue. But this guarantees nothing, he says. "One hundred per cent safety is impossible through technology," says Dr. Inoue. This is because ultimately no matter how thorough you are, you cannot anticipate the unpredictable nature of human behaviour, he says. Or to put it another way, no matter how sophisticated your robot is at avoiding people, people might not always manage to avoid it, and could end up tripping over it and falling down the stairs.
Legal problems
In any case, says Dr. Inoue, the laws really just summarize commonsense principles that are already applied to the design of most modern appliances, both domestic and industrial. Every toaster, l
