2．It means that more heat energy tends to be trapped in the atmosphere causing the global temperature to go up.
[句式分析] 本句是一个复合句。that 引导一个宾语从句；causing the global temperature to go up 为现在分词短语作结果状语。
[自主翻译] 它意味着更多的热能将被困在大气层中，从而引起全球气温上升。
3．On the other hand，there are those，like George Hambley，who are opposed to this view and believe that we should not worry about high levels of carbon dioxide in the air.
[句式分析] 本句是一个复合句。there are those，like George Hambley是主句。who are opposed to this view and believe that we should not worry about high levels of carbon dioxide in the air为who 引导的定语从句。该定语从句又分为两部分，由and 连接。are opposed to this view为一部分；believe that we should not worry about high levels of carbon dioxide in the air为另一部分，其中含有一个that引导的宾语从句。

Ⅰ.阅读理解
A
You might think that “global warming” means nothing more than a rise in the world’s temperature.But rising sea levels caused by it have resulted in the first evacuation(撤离) of an island nation—the citizens of Tuvalu will have to leave their
homeland.
During the 20th century，sea level rose 8－12 inches.As a result，Tuvalu has experienced lowland flooding of salt water that has polluted the country’s drinking water.
Paani Laupepa，a Tuvaluan government official，reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years.Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.
Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol，an international agreement calling for industrialized nations to reduce their greenhouse gas emissions，which are a main cause of global warming.“By refusing to sign the agreement，the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years，” Laupepa told the BBC.
Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.
Tuvalu is not the only country that is vulnerable(易受影响的) to rising sea levels.Maumoon Gayoon，President of the Maldives，told the United Nations that global warming has made his country of 311,000 an “endangered nation”．
语篇解读 本文主要讲述了全球变暖对于某些岛国，特别是对图瓦卢所造成的恶劣影响。 1．The text is mainly about . A．rapid changes in the earth’s temperature B．bad effects of global warming C．moving of a country to a new place D．reasons for lowland flooding 答案 B
解析 主旨大意题。这篇短文主要讲述了全球变暖造成的恶劣影响。
2．According to scientists，the DIRECT cause of more and fiercer storms is . A．greenhouse gas emissions in industrialized nations B．higher surface water temperatures of the sea C．continuous global warming D．rising sea levels 答案 B
解析 推理判断题。根据第三段中的“Many scientists connect higher surface water
temperatures resulting from global warming to greater and more damaging storms.”可以推断出一些科学家认为造成严重的暴风雨的直接原因是海洋表面水温升高。
3．Laupepa was not satisfied with the United States because it did not . A．agree to reduce its greenhouse gas emissions B．sign an agreement with Tuvalu C．allow Tuvaluans to move to the US
D．believe the problems facing Tuvalu were real 答案 A
解析 推理判断题。根据第四段第一句话可知，Laupepa对美国不满意的原因是美国拒绝签署减少导致温室效应气体排放的国际公约。
4．The country whose situation is similar to that of Tuvalu is . A．Australia C．the Maldives 答案 C
解析 推理判断题。根据最后一段可推断出马尔代夫(the Maldives)与图瓦卢的情况相似。
B
Our world has been greatly affected by climate change and it is important that people，young and old，work together to fight it.Perhaps the biggest factor is the action of our children.That is why I think it is important that children today learn to be eco-friendly at a young age.
I believe the nation should require schools to have a class about being “green”—Green Living could be its name.Every school would teach students about global warming，its effects and what they can do to reduce their carbon footprint.
In the classes，students could be assigned(分配) to find solutions to everyday energy problems，while learning about their effects on the earth and how they all can help.Students would be encouraged to use what they learned in class at home，where it would affect the whole family.
Too many think that global warming is not a threat，but it is one of our biggest problems.How are children supposed to prevent global warming if they grow up not knowing about its dangers？Children should be exposed to ways they can help in elementary school，which is why it is important that more schools offer environmental education classes.
However，to be effective，schools must take steps to be “green” too.What would children be learning if the school’s lights were always left on and there were no
B．New Zealand D．the United States
recycling bins？When schools are rebuilt or new ones are built，towns should support an eco-friendly design that would save energy and reduce power bills.
Green living and green schools are part of a new wave that should be sweeping the nation，but is not.How will our future leaders respond after years of living in a community where preserving our world’s natural integrity(完整性) just isn’t considered important？Schools and the government should be responsible for teaching young people about global warming quickly.Seriously，how many people does it take to screw in a fluorescent light(荧光灯) bulb?
语篇解读 本文主要论述了学校应教育孩子们从小了解绿色生活、气候变暖的知识。 5．In “green living” class，children will . A．learn the ways to save energy
B．be asked to find solutions to global warming
C．be encouraged to experiment with their effects on the earth D．help reduce the carbon footprint of their friends 答案 A
解析 细节理解题。根据第三段第一句可知，学生在课堂上可以学到节能的方法。 6．More schools offer environmental education classes to make children . A．realize that global warming is not a threat B．help to solve global warming from an early age C．treat global warming as one of the biggest problems D．know about the danger of preventing global warming 答案 B
解析 细节理解题。结合第四段最后一句可知，学校提供环境教育课的原因是使孩子们在很早就可以接触到解决气候变暖的方法。
7．What steps can be considered to be green?
A．The towns should be designed in an eco-friendly way. B．Schools should be enlarged to save energy.
C．Turn off the school’s lights when everyone leaves. D．Recycling bins should be new ones at school. 答案 C
解析 细节理解题。根据第五段第二句“What would children be learning if the school’s lights were always left on and there were no recycling bins？”可知，当教室里没人时，把灯关掉就是使学校“绿色化”的举措之一。
8．What might be the most suitable title for the passage?
