international agreements relating to the environment because of economic concerns unique to each country.It is no longer enough to try to forbid certain activities or to reduce giving off certain substances.二、阅读理解第80页/共107页The global challenges of the interlink between the environment and development increasingly 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 giving off harmful substances to the ozone layer(臭氧层).第81页/共107页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.第82页/共107页 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 tough measures taken in some countries,would be of no use if other countries do not control their giving off.Whereas the UN team on climate change has found that the carbon dioxide would have to be cut globally by 60%.第83页/共107页This path does not work for several reasons.Such deep cuts would cause a breakdown of the world economy.Many developing countries are not yet willing to control 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.第84页/共107页Such a mission would require a degree of shared vision and common responsibilities new to humanity.Success lies in the force of imagination,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 following tropical disease,especially where had been none.第85页/共107页1.The main purpose of the passage is to_.A.convince people that global warming is a threatB.criticize some countries for refusing to cut down giving off harmful substances to the ozone layerC.analyze th
