At the Kyoto conference on global warming in December 1997, it became abundantlyclearhow complex it has become to work out international agreements relating to the environmentbecause of economic concerns unique to each country. It is no longer enough to try to forbidcertain activities or to reduce emissions of certain substances. The global challenges of theinterlink between the environment and development increasing bring us to the core of the economic life of states. During the late 1980s we were able, through international agreements, to make deep cuts in emissions harmful to the ozone layer. These reductions were made possible because substitutions had been found for many of the harmful chemicals and, more important, because the harmful substances could be replaced without negative effects on employment and the economies of states. Although the threat of global warming has been known to the world for decades and all countries and leaders agree that we need to deal with the problem, we also know that the effects of measures, especially harsh measures taken in some countries, would be nullified (抵消) if other countries do not control their emissions. Whereas the UN team on climate change has found that the emissions of carbon dioxide would have to be cut globally by 60% to stabilize the content of CO, in the atmosphere, this path is not feasible for several reasons. Such deep cuts would cause a breakdown of the world economy. Important and populous (人口众多的 ) low or medium-income countries are not yet willing to undertake legal commitments about their energy uses. In addition, the state of world technology would not yet permit us to make such a big leap. We must, however, find a solution to the threat of global warming early in the 21st century.Such a commitment would require a degree of shared vision and common responsibilities new to humanity. Success ties in the force of imaginations, in imagining what would happen if we fail to act. Although many living in cold regions would welcome the global-warming effect of a warmer summer, few would cheer the arrival of the subsequent tropical diseases, especially where there had been none.

Surprisingly enough， we are going to advocate that parents act rudelyat least as far as the TV set is concerned. Most of us have been socialized ill our lives with the warning， Dont interrupt when someone else is speaking. Yet our ancestors never imagined a mechanical visitor sitting in the middle of our home who talks without stop and never allows the listener an opportunity to put a word in edgewise.During our research， we found upon questioning parents that they usually reacted to TV content they disliked or disagreed with by remaining silent. This brings to mind an old saying that parents might well be advised to consider， Silence gives consent.We advocate loud reactions and exclamations of disapproval when something is presented on TV which is in opposition to the familys values or offends them in any way. Similarly， when a program is in accordance with the familys views， parents should approve of its content and applaud loudly. There is much that Shakespearean audiences of old could teach us in regard to such spontaneous， public reactions. Silence is misleading to our children.This process of direct interventionvocal approval or disapproval of TV content is highly effective with young children， because they are curious， learning rapidly and ready to place a great deal of confidence in the information and attitudes of their parents and other significant adults， such as teachers. For teenagers indirect intervention is recommended， because this group is more resistant to adult statements and does not like to be lectured.Indirect intervention is the practice of making comments about TV to other members of the family， but in such a way that teenager is sure to overhear the comments.Our research shows that through such parental comments of approval or disapproval， adults can dramatically influence the information their children receive and retain from watching TV.

B. hope that school or society can do something to control bad TV programs. C. feel that they can exert some influences on their children at home only.

By advocating that parents act rudely， the author means that parentsA. shouldnt conceal their motions about some of the programs.B. shouldnt hesitate to take control over the TV set at least，C. should punish children for not listening to them.D. should act as our ancestors did in respecting others in conversation.71.

Control of TV influence on children.The Timber rattlesnake, once widespread throughout the eastern United States, is now on the endangered species list and is extinct in two eastern states in which it once thrived. Compared to its western cousins, the Timber rattlesnake may be especially vulnerable because of certain behaviors adapted for coping with the cold climate in which it lives.Rattlesnakes are generally found in warm climates because, like all reptiles, they cannot generate or regulate their own body temperature incternaly and must rely on the suns warmth for heat. But Timber rattlesnakes migrated into colder northern areas about 8,000 years ago when glaciers (冰川) retreated. In these northern regions, the snakes developed a number of adaptive strategies to survive, but ultimately these behaviors make them more vulnerable to human predation, their main threat.One survival strategy the snakes have developed is hibernation. For approximately eight months of the year, the rattlers remain motionless in deep frost-free crevices, with their body temperature dropping as low as 40 degrees. In the spring when they emerge, they must warm their chilled bodies by sunning themselves for three or four days on rocks in the open. This behavior, coupled with the fact that Timber rattlesnakes tend to concentrate in large numbers at their wintering sites, makes them easy prey. Gestating females are particularly vulnerable because they spend much of their time basking in the sun in order to produce live young from eggs. In addition, females have very long interbirth intervals, producing live young only every three to five years. If a frost or cold spell comes late in the year, the entire litter of six to twelve young may die.Efforts are under way to protect the Timber rattlesnake and its habitat from further human depredation, but in many states it is already too late.
