Some politicians are scurrying about with much zest and anticipation. It's time, their polls inform. them, to find the quick fix for what they have determined is a society plagued by the irregular heartbeat of deficient values.
But there are contradictions that intrude on this denunciatory atmosphere. If there are moral omissions in the society, they cannot be sealed by instant, slenderly based attacks on entertainment. The plain fact is we are rearranging our priorities in the wrong way.
We are today misplacing our energies and our funding by directing all sorts of incentives to high schools and colleges. Too late. The moral scaffolding has been built by then, for better or worse. How then to begin this revision of life conduct？ We must introduce in pre-school, and keep alive through grade five, a new school course.
The course could be titled, "What is right, and what is plainly wrong." For 30 minutes each day, the teacher would illuminate for these very young children what William Faulkner labeled "the old verities," the words that construct and implement the daily moral grind in which every durable society must engage if it is to be judged a "just" society.
These are words like duty, honor, service, integrity, pity, pride, compassion and sacrifice, plus the clear admonition that violence is wrong. To the teaching of the meaning of those words must be added that cleansing rule of treating other people as you would want them to treat you. And most of all to make sure that these kids understand with growing clarity that home, school and church are the sanctuaries for their later life.
There is a grand simplicity to this kind of school course. It enters a child's mind early, burrowing deep into those recesses of the human brain that even today advanced medical science has not been able to penetrate.
If you ask 'enough people, you will find that most of us remember our first- or second-grade teacher. I remember Miss Corbett and Miss Walker, who read to us before we really understood, but the words had weight and allure. We listened and, without really knowing it, we learned and saved what we learned. Perhaps it was because what we heard in those early school years was the first entry into our learning vessel.
Absent this kind of early instruction, absent the building of this moral shield, no congressional law, no presidential executive order, no fiery rhetoric will salvage a child's conduct nor locate a missing moral core.
According to the author, some politicians attribute the society's deteriorated moral values to ______.
A．fasterB．moreC．betterD．harder
The technique, described in the journal, Nature, uses a thermal camera to detect sudden, involuntary shifts of blood flow in the face. The system performed as accurately as a traditional polygraph, the scientists report.
Yet the camera can provide answers instantly, and does not require a highly trained specialist to operate it or interpret its results. This makes it far better suited than the polygraph for a new, high-tech approach to security that is already raising the hackles of civil libertarians: the screening of large numbers of citizens, at airports and other sensitive areas, who have done nothing wrong.
"The next decade is going to see the development of truly accurate lie detectors," said Stephen M. Kosslyn, an expert on detecting lies and a professor of psychology at Harvard University.
The prototype, built by researchers at the Mayo Clinic and Honeywell Laboratories in Minnesota, is at least 2 years from being ready for general use. But other scientists said the discovery of previously unknown physiological changes in the face was itself an important step forward.
"This is potentially very important work, which may open a new window on the mind," said Kosslyn.
Pushed by technological advances, and with fresh interest, since Sept. 11, the discovery is part of a boom in the scientific study of deceit and its detection. Although the lie remains a mysterious phenomenon, researchers in recent years have found a number of new approaches that might replace the polygraph, from brain scans, to subtle changes in eye movement, to sparks of electrical activity that signal a person has seen a victim or a crime scene before.
The new finding, though, is remarkable for its simplicity. When a person tells a lie, the team found, there is a sudden rush of blood to the area around the eyes, according to the Mayo Clinic's Dr. James A. Levine. Although the change is not: ordinarily visible, the blood warms the skin, causing hands of color to appear through a camera sensitive to heat.
The team devised a computer program that can identify the telltale changes based on the camera images. In testing at the US Department of Defense Polygraph Institute, which trains federal polygraph examiners, the device performed better than polygraphs, with 85 percent accuracy compared with 70 percent for the polygraph.
Compared with a traditional polygraph a thermal camera ______.
