According to Bruce Anderson，before 1970，Americans had little idea about ________.‎ A．the social movement B．recycling techniques C．environmental problems D．the importance of Earth Day 解析：选C　细节理解题。根据文章首段Bruce 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。‎ ‎2．Where does the support for environmental protection mainly come from?‎ 7‎ A．The grassroots level.‎ B．The business circle.‎ C．Government officials.‎ D．University professors.‎ 解析：选A　细节理解题。根据文章第二段中的“Business people, political leaders，university professors, and especially millions of grassroots Americans are taking part in the movement.”可知商人、政界领导、大学教授、尤其是平民百姓们都参与了保护环境运动，由此判断保护环境的支持主要来自草根阶层。‎ ‎3．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.‎ 解析：选D　细节理解题。根据文章倒数第二段中的“In 1988 there were only 600 recycling programs ...and building designs have helped save a lot of energy and therefore prevented pollution.”可知回收工作的改进，先进产品或者住房设计的研制开发等其结果都是有效减少了污染，改善了环境，故答案选D。‎ ‎4．What is especially important for environmental protection according to the last paragraph?‎ A．Education.　　　　　　 B．Planning.‎ C．Green living. D．CO reduction.‎ 解析：选A　主旨大意题。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的意识，改善环境问题方面至关重要。‎ Ⅳ.完形填空 When I smoked with my family，I would feel so __1__ and good that nothing else in the world seemed so __2__.I thought that smoking weed (烟草) was okay since many of my family members and people at my school smoked.__3__ ever happened to them.__4__ I started smoking weed a lot more during lunch and after school.I never thought __5__ of it.At that time I just wanted to smoke.Then I began to __6__ in school.I would __7__ classes，come home late and spend all my money.I would spend __8__ 8 to 18 dollars a day.I never thought __9__ about the bad effect that marijuana (大麻) had on those things.Maybe my coming to class high (神志恍惚) was the reason why I was failing or coming home late.As I continued to smoke marijuana，I began to notice 7‎ ‎ that I would always have the strong desire to smoke and that I would get __10__ cigarettes if I smoked those，but I don't.__11__ I have learned more about marijuana，I have __12__ the amount of marijuana that I use.I don't want marijuana to be the most important in my life.I'm not smoking every day，and not spending as much money.Since I have __13__ on my habit，I am __14__ more money.I'm ready to go back to school and do good，so that I can make myself __15__.Everyone is always saying how weed __16__ your mind and how it solves problems.I think it only brings more __17__.Marijuana is not good for your body or your brain.I'm not trying to tell you not to smoke;
