Since the first Earth Day in 1970,Americans have gotten a lot"greener"toward the environment."We didn't know at that time that there even was an environment,let alone that there was a problem with it,"says Bruce Anderson,president of Earth Day USA.
But what began as nothing important in public affairs has grown into a social movement.Business people,political leaders,university professors,and especially millions of grassroots Americans are taking part in the movement."The understanding has increased many,many times,"says Gaylord Nelson,the former governor from Wisconsin,who thought up the first Earth Day.
According to US government reports,emissions from cars and trucks have dropped from 10.3million tons a year to 5.5 million tons.The number of cities producing CO beyond the standard has been reduced from 40 to 9.Although serious problems still remain and need to be dealt with,the world is a safer and healthier place.A kind of"green thinking"has become part of practices.
Great improvement has been achieved.In 1988there were only 600 recycling programs; today in 1995there are about 6,600.Advanced lights,motors,and building designs have helped save a lot of energy and therefore prevented pollution.
Twentyfive years ago,there were hardly any education programs for environment.Today,it's hard to find a public school,university,or law school that does not have such a kind of program."Until we do that,nothing else will change!"says Bruce Anderson.

32.According to Anderson,before 1970,Americans had little idea about___.
A.the social movement     
B.recycling techniques
C.environmental problems
D.the importance of Earth Day
33.Where does the support for environmental protection mainly come from?___
A.The grassroots level.
B.The business circle.
C.Government officials.
D.University professors.
34.What have Americans achieved in environmental protection?___
A.They have cut car emissions to the lowest.
B.They have settled their environmental problems.
C.They have lowered their CO levels in forty cities.
D.They have reduced pollution through effective measures.
35.What is especially important for environmental protection according to the last paragraph?___

答案和解析
32.C 细节理解题.根据第一段Anderson说的话"We didn't know at that time there even was anenvironment,let alone that there was a problem with it,可知,当时人们不知道环境这个概念,更别说环境问题了,故选C.
33.A 细节理解题.根据第二段.的Business people,political leaders,universityprofessors,and especially millions of grass-roots可知,商人,政界领导,大学教授,尤其是平民百姓们都参与到了保护环境的运动中来,所以保护环境的支持主要来自草根阶层,故答案选A.
34.D 细节理解题.根据倒数第二段的In 1988 there were only 600 recycling programs …and building designs have helped save a lot of energy and therefore preventedpollution.可知,回收工作的改进,先进产品和住房设计的研制开发等措施都有效地减少了污染,改善了环境,故答案选D.
35.A 主旨大意题.四个选项内容对于保护环境都是重要的,但是作者在文章末段提到目前几乎每所学校都有关于环境保护的课程,而且通过最后Bruce Anderson说的话"Until we do that,nothing else will change!"可知,教育在改变人们保护环境意识,改善环境问题方面至关重要,故答案选A.
