The environmental crisis is the result of success in cutting down the morality of infants (which has given us the population explosion), success in increasing farm output sufficiently to prevent mass famine, success in getting people out of the tenements of the 19th century city and into the greenery anti privacy of single family home in the suburbs (which has given us urban sprawl and traffic jams). The environmental crisis, in other words, is the result of doing too much of the right sort of thing at large.
To overcome the problems that success always creates, one mast build on it. But where to start? Cleaning up the environment requires determined, sustained effort with clear targets and deadlines it needed, above all, concentration of effort. Up to now we have tried to do a little bit of everything, what we ought to do first is to draft a list of priorities.
This passage assumed the desirability of ______.
A.living in comfortable family life-style
B.setting disputes peacefully
C.combating cancer and heart disease with energetic research
D.having greater government involvement in people's daily life
Character is made up of those principles and values that give your life direction, meaning and depth. These constitute your inner sense of what's right and wrong based not on laws or rules of conduct but on who you are. They include such traits as integrity, honesty, courage, fairness and generosity--which arise from the hard choices we have to make in life. So wrong is simply in doing wrong, not in getting caught.
Yet some people wonder if our inner values matter anymore. After all, hasn't our noted bank executive succeeded in every visible way, despite his transgressions (过错,犯罪)?
This question demonstrates a quandary (因境) of our modern life. Many have come to believe that the only things we need for success are talent, energy and personality. But history has taught us that over the long haul, who we are is more important than who we appear to be.
During the nation's first century and a half, almost everything in the literature of success and self-help focused on what could be called the character ethic. Such eminent figures as Benjamin Franklin and Thomas Jefferson made clear their belief that we can only experience tree success and happiness by making character the base of our lives.
After we moved into the industrial age and after World WarⅠ, the basic view of success shifted to what we could call the personality ethic. Success became more a function of charm, skills and techniques that, at least on the surface, lubricate (使润滑) the process of human interaction. Rather than struggle with thorny issues of right and wrong, we turned to making things run smoothly.
Some of that philosophy expressed itself with harmless but superficial maxims such as "Smiling wins more friends than frowning." Other ideas were clearly manipulative or even deceptive-faking interest in others' hobbies so they will like you, for instance.
With a value system based solely on skill and personality, we find heroes in athletes, musicians and in powerful business executives. But despite the admiration we feel for these achievers, we shouldn't necessarily look upon them as role models. While skill is certainly needed for success, it can never guarantee happiness and fulfillment. These come from developing character.
According to the passage, character is().
A.your integrity
B.your personality
C.a guide in your life
D.your sense of good
"It wasn't clear how long children in the first year of life could retain a memory of an event," Liston says. We were interested in testing the hypothesis that neurological developments at the end of the first year and the beginning of the second would result in a significant Enhancement in this kind of memory.
Liston showed a simple demonstration to infants ages 9, 17, or 24 months old. The test results showed a huge difference between the test children Who had been 9 months old when they saw the first demonstration and those who had been older. "Whereas 9-month-olds don't I really remember a thing after four months, 17-and 24-month-olds do," Liston says. "Something is happening in the brain between 9 and 17 months old that enables children to encode these memories efficiently and in such a way that they can be retained and retrieved after a long period of time," Liston says. Researchers believe that changes in certain regions of the brain's frontal lobe and the hippocampus, which axe associated with memory retention and retrieval, drive the rapid expansion of childhood recall. Previous studies have shown that the frontal lobes in humans begin to mature during the last quarter of the first year of life.
Liston's work may help explain why adults can rarely remember anything from before their second birthday or so. Most people simply accept this "infant amnesia" as a fact of life. "But it's not clear why a 40-year-old has plenty of memories for something that happened 20 years ago, but a 20- year-old has basically no memories for something that happened when he was 2 or 3 ," Liston says. He suggests that the same brain mechanisms that were not yet able to encode long-term memories in 9-month-olds may also play some role in adults' inability to remember events of infancy. Researchers still need to look at other areas of cognition -- such as what role language ability plays in memory -- to really fully understand why people can' t remember anything that happened before 2--3 years of age. But one thing is clear: When l-year-old Snookums claims he doesn't remember breaking the heirloom chitin five months ago, he's almost surely telling the truth.
Conor Liston ______.
A.has only a vague understanding of infants' poor memory
B.has found something more about the origin of long-term recall
C.has detected the regions of the brain responsible for memory-processing
D.has established a theory about memory development
(79) There can be no doubt that the growth in advertisement is one of the most striking features of the western world in this century. Many businesses such as those handling frozen foods, liquor, tobacco and medicines have been built up largely by advertisement. We might ask whether the cost of advertisement is paid for by the producer or by the customer. Since advertisement forms part of the cost of production, which has to be covered by the selling price, it is clear that it is the customer who pays for the advertisement. How ever, if large—scale advertisement leads to increased demand, production costs are reduced, and the customer pays less.
It is difficult to measure exactly the influence of advertisement on sales. When the market is growing, advertisement helps to in crease demand. When the market is shrinking, advertisement may prevent a bigger fall in sales than would occur without its support. (80) What is clear is that businesses would not pay large sums for advertisement if they were not convinced of its value to them.
Advertisement is often used to ______.
A.deceive customers
B.increase production
C.arouse suspicion
D.push the sale
