The Development of Personality
Personality is to large extent inherent. A-type parents usually bring A-type
offspring. But the environment must also have a profound effect, since if
competition is important to the parents, it is likely to become a major factor
in the lives of their children. One place where children soak
up (浸泡) a characteristic is school, which is, by its very nature, a highly
competitive institution. Too many schools adopt the "win at all costs" moral
standard and measure their success by sporting achievements. The current passion
for making children compete against their classmates or against the clock
produces a two-layer system, in which competitive A-types seem in some way
better than their B-type fellows. Being too keen to win can have dangerous
consequences: Remember that Philippines, the first marathon runner, dropped dead
seconds after saying, "Rejoice, We conquer!" By far the worst
form of competition in schools is the disproportionate emphasis on examinations.
It is a rare school that allows pupils to concentrate on those things they do
well. The merits of competition by examination are somewhat questionable, but
competition in the certain knowledge of failure is positively harmful.
Obviously, it is neither practical nor desirable that all A youngsters
change into B's. The world needs types, and schools have an important duty to
try to fit a child's personality to hide possible future employment. It is top
management. If the preoccupation of schools with academic work
was lessened, more time might be spent teaching children surer values. Perhaps
selection for the caring professions, especially medicine, could be made less by
good grades in chemistry and more by such considerations as sensitivity and
sympathy. It is surely a mistake to choose our doctors exclusively form A-type
stock. B's are important and should be encouraged.

Artificial Speech
Because speech is the most convenient form of communication, in the future
we want essentially natural conversations with computers. The primary point of
contact will be a simple device that will act as our window into the world. It
will have to be small enough to slip into pour pocket, so there will be a screen
but no keyboard: you will simply talk to it. The device will be permanently
connected to the Internet and will beep relevant information up to you as it
comes in. Such devices will evolve naturally in the next five to ten
years. Just how quickly people will adapt to a voice-based
Internet world is uncertain. Many believe that, initially at least, we will need
similar conventions for the voice to those we use at present on screen : click,
back, forward, and so on. But soon you will undoubtedly be able to interact by
voice with all those IT-based services you currently connect with over the
Internet by means of a keyboard. This will help the Internet serve the entire
population. Changes like this will encompass (围绕、包围) the whole
world. Because English is the language of science, it will probably remain the
language in which the technology is most advanced, but most speech, recognition
techniques are transferable to other languages provided (假如、若是) there is
sufficient motivation to undertake the work. Of course, in any
language there are still huge problems for LIS to solve. Carefully dictated,
dear speech can now be understood by computers with only a 4~5 percent error
rate, but even the most advanced technology still records 30~40 percent errors
with spontaneous' speech. Within ten years we will have computers that respond
to goal-directed conversation, but for a computer to have a conversation that
takes into account human social behaviors is probably 50 years off. We are not
going to be chatting to the big screen in the living room just yet.
In the past insufficient speed and memory have held LIS back, but these
days they are less of an issue. However, there are those in the IT community who
believe that current techniques will eventually hit a brick wall. Personally, I
believe that incremental (不断增长的)developments in performance are more likely. But
it is true that by about 2040 or so, computer architectures will need to become
highly parallel(并行的) if performance is to keep increasing. Perhaps that will
inspire some radically new approaches to speech
understanding that will replace the methods
we are developing now.
单选题Snow Ranger The two things, snow and mountains, which are needed for a ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain, often called "White Death." It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937, 38 at Alta, Utah, in Wasatch National Forest. This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a major ski area. Thus, development of Alta and other major ski resorts in the west was dependent upon controlling the avalanche. The Forest Service set out to do it, and did with its corps of snow rangers. It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber. He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better. He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down. The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety for people on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, or talks with the ski area's operator as he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes.

单选题 Lateral Thinking Lateral thinking (迂回思维), first described by Edward de Bono in 1967, is just a few years older than Edward’s son. You might imagine that Caspar was raised to be an adventurous thinker, but de Bono name was so famous, Casper’s parents worried that any time he would say something bright at school, his teachers might snap, “Where do you get that idea from?” “We had to be careful and not overdo it,” Edward admits. Now Casper is at Oxford —— which once looked unlikely because he is also slightly dyslexic (通读困难). In fact, when he was applying to Oxford, none of his school teachers thought he had a chance. “So then we did several thinking sessions,” his father says, “using my techniques and, when he went up for the exam, he did extremely well.” Soon after, Edward de Bono decided to write his latest book, “Teach Your Children How to Think”, in which he transforms the thinking skills he developed for brain-storming businessmen into informal exercises for parents and children to share. Thinking is traditionally regarded as something executed in a logical sequence, and everybody knows that children aren’t very logical. So isn’t it an uphill battle, trying to teach them to think? “You know,” Edward de Bono says, “if you examine people’s thinking, it is quite unusual to find faults of logic. But the faults of perception are huge! Often we think ineffectively because we take too limited a view.” “Teach Your Child How to Think” offers lessons in perception improvement, of clearly seeing the implications of something you are saying and of exploring the alternatives.
