Ⅰ.阅读理解

A

Mother Nature is a cruel mistress.Why? Read on to find the answer.

Venice

This iconic city is sinking rapidly.The canals that make up the streets of Venice rise 2mm every year，making relics of history go under the surface of water and destroying architecture.Experts warn that without intervention (干预)，this city will disappear back into the water at an even faster rate，consumed by rising sea level from melting polar ice caps.

Machu Picchu

These Incan ruins have drawn adventurous tourists into the mountains of South America.The forces of natural erosion have been accelerated by tourism and this landmark faces severe influence from increasing foot traffic.The Peruvian government recently suggested a cable car that would cut out the intense hike up to the ruins，making the site instantly accessible to millions，but the future of Machu Picchu remains uncertain.

Glacier National Park

Perhaps you've heard that the ice caps are melting.But nowhere is more apparent in the United States than in Glacier National Park.Estimates indicate that the glaciers that are part of the beauty of this national landmark will disappear entirely in the next two decades.

The Great Barrier Reef

Hidden from view beneath the waves，the Great Barrier Reef has been rapidly dying off.Nearly fifty percent of coral which once occupied a large area is gone，destroyed by pollution and disease.

C．It's well preserved by the locals.

D．It bears a heavy burden of tourism.

D[细节理解题。根据Machu Picchu部分中的“The forces of natural erosion have been accelerated by tourism and this landmark faces severe influence from increasing foot traffic.”可知，旅游业给该地带来了破坏，即带来了沉重的生存负担。故选D。]

2．Which place probably needs visitors to dive into the water to enjoy its beauty?

A．Venice.

B．Machu Picchu.

C．Glacier National Park.

D．The Great Barrier Reef.

D[细节理解题。根据The Great Barrier Reef部分中的“Hidden from view beneath the waves”可知，该地可能需要游客潜入水中才能享受其美景。故选D。] 3．What do the above attractions have in common?

A．They all have a long history.

B．They're all threatened by climate change.

C．They're all in danger of disappearing.

D．They're all well-known for natural scenery.

C[推理判断题。根据Venice部分中的“this city will disappear back into the water at an even faster rate”，Machu Picchu部分中的“the future of Machu Picchu remains uncertain”，Glacier National Park部分中的“the glaciers that are part of the beauty of this national landmark will disappear entirely in the next two decades”及The Great Barrier Reef部分中的“the Great Barrier Reef has been rapidly dying off”可推知，这几处旅游胜地的共同点是它们都濒临消失。文章第一段的内容也是暗示，故选C。]

B

Since the first Earth Day in 1970，Americans have gotten a lot “greener”

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.

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 grass-roots 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 (排放) from cars and trucks have dropped from 10.3 million tons a year to 5.5 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 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.

【语篇解读】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。以前在公共事务中无足轻重的环境问题现在成了一项社会问题，从科学家到大学教授再到平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。

4．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

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。] 5．Where does the support for environmental protection mainly come from?

A．The grass-roots level.

B．The business circle.

C．Government officials.

D．University professors.

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 grass-roots 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。]

6．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.

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有效减少了污染，改善了环境，故答案选D。] 7．What is especially important for environmental protection according to the last paragraph?

A．Education.B．Planning.

C．Green living. D．CO reduction.

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。] Ⅱ.阅读七选五
