Since the first Earth Day in 1970,American have gotten a lot “greenter” toward the environment . “We didn’t know at that time there even was an environment,let alone that there was a problem with it,”says Bruce Anderson,president of Earth Day USA.

Great improvement has been achieved .In 1988 there were only 600 recycling programs ,; today in 1995 there are about 6,600 .Advanced lights ,motors , and building designs have helped save a lot of energy and therefore prevented pollution .
Twenty –five 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! ” say Bruce Anderson .

题目分析: 本文属于记叙文题材。在文章中作者介绍了自从1970年第一个地球日成立以来，美国的环境问题有了很大的改善。以前在公共事物中无足轻重的环境问题现在成立一项社会问题，从科学家到大学教授到贫民百姓都有了环保意识。而且作者指出教育在这种变化方面也起着非常重要的作用。
小题1:C 考查细节理解。根据文章首段Anderson说的话“We didn’t know at that time there even was an environment,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，由此可知答案选C。
