Passage 2.

　　It’s a day to celebrate, a time to educate, and a way to make a difference. Earth day was first observed on April 22, 1970. the tradition began in the united states and is now an international focal point for people who are concemed about the environment.

　　Imagine a time before the Clean Air Act, the Clean Water Act, the Endangered Species act, and even the environmental Protection Agency. Hot topics of the time were industrial pollution, nuclear accidents, oil dependency, pesticides, and a vanity of social issues. However,olicymakers were not yet acting on many important environmental problems.

　　Earth day grew ort of grassroots action and institutional support. Student leader Denis Hayes and Wisconsin Senatour Gaylord Nelson were two key organizers for the firwt event. Over 20 million concerned citizens rallied for clean air and water. College students were a major force in the campaign, although participants of all ages were involved. Still, we cannot really credit a handful of individuals for the success of Earth Day. After all, a major message of Earth Day is that every single person has an important role in the environment.

　　The first Earth Day was very successful, inspiring the passage of congressional protection for air, water, and endangered species. Momentum from the demonstration also fueled the formation of the Environmental Protection Agency.

　　Thirty years later, the focus has changed but the urgency remains the same. Due to increasing amounts of scientific evidence that fossil fuels are changing the global climate, the theme for Earth Day 2000 is Clean Energy. The four major goals of Earth Day 2000 are clean cars, clean power, clean air, and clean investments.

　　1. April 22nd, 2000 is the ____ years’ anniversary of the Earth Day.

　　A. 30th B. 20th C. 10th D. 100th

　　答案：　A

　　考點：　該題考的是如何找出數(shù)字表示的細節(jié).

　　解析：　提問的是2000年4月22日是地球日的多少周年紀念日.回答用數(shù)字表示的細節(jié)時，需要進行簡單計算.從原文的第一段我們可以知道，地球日最早1970年4月22日在美國開始.剛好是30年紀念日.所以，選項A為本題的答案.

　　2. _____ originated the Earth Cay.

　　A. College students. B. Policy makers. C. Ordinary people. 　D. Denis Hayes.

　　答案：　C

　　考點：　該題是一個就文章事實進行提問的細節(jié)詢問題.

　　解析：　本題提問的是地球日是由誰發(fā)起的.這個問題答案需在第三段里找出.該段第一句告訴我們，地球日是群眾自發(fā)活動，并由社會機構(gòu)支持的.學(xué)生領(lǐng)袖Denis Hayes和威斯康星州議員Gaylord Nelson是第一次活動的主要組織者;200多萬市民聚集起來，呼吁干凈的水源和空氣.各個年齡階層的人都參加了這次集會，大學(xué)生在這次活動中是主要力量，但是我們不能確切地說地球日的成功歸為哪一部分人.由這一段話的意思我們可以得知，地球日的創(chuàng)建是集體的結(jié)果，并不是由哪一個人創(chuàng)建的.所以，正確答案是C.

　　3. Which of the following is the immediate effect of the first Earth Day?

　　A. The Environmental Protection Agency was founded.

　　B. Congressional Protection for water was passed.

　　C. There are more demonstrations followed.

　　D. Denis Hayer published his Clean Energy Now.

　　答案：　B

　　考點：　該題是對文章的一個主要事實的判斷分析題.

　　解析：　本題提問的是以下哪一個是第一個地球日的直接影響所致.該題的答案含在文章的第四段中.這段話的意思是一個地球日極為成功，國會因此而通過了對空氣，水，受害生物保護法;游行的勢頭也推動了環(huán)保機構(gòu)的成立.由此可見，它直接影響的是B(國會通過了水保護法);因此，答案為B.

　　4. Which of the following is not the goal of Earth Day 2000?

　　A. clean air 　　　　　　 B. clean water

　　C. clean automobiles 　　D. clean investment.

　　答案：　B

　　考點：　該題基于文章內(nèi)容判斷的細節(jié)詢問題.

　　解析：　本題提問的是以下哪一個不是2000年地球日的目標.所給的四個答案分別為：A(空氣凈化)，B(水凈化)，C(汽車凈化)和D(投資凈化).通過原文最后一句我們可以知道，2000年地球日的目標是汽車凈化，能源凈化，空氣凈化和投資凈化.由此可知，只有選項B不屬于其內(nèi)容.所以，B為本題答案.

　　5. Earth Day is a day to ____.

　　A. increase fossil fuels B. purify the water

　　C. solve social issues D. protect environment.

　　答案：　D

　　考點：　該題考的是通過文章的主題思想對所給選項作出判斷.

　　解析：　本題提問的是地球日是什么日子.從全文第一段的最后一句我們可以知道，源于美國的地球日今天是所有關(guān)心環(huán)境問題的人們關(guān)注的焦點.而且，整篇文章也從地球日的起因起及其所產(chǎn)生的一系列影響告訴我們，它是一個保護環(huán)境的日子.所以，正確答案為D.
