题目内容

Tuvalu, north of Fiji, is a tiny country in the Pacific Ocean.
Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five metres above sea level. Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetable. It fears it will be swallowed up by the sea. Without urgent help, the country's days are numbered.
But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050.A century ago, St. Mark's Square, the lowest point in the city, flooded about nine time a year. Nowdays it happens more than 100 times.
While Venice is slowly sinking into the mud on which it stands, Tuvalu's rising sea level is caused by global warming.
The average global temperature has increased by almost 0.5 centigrade degree over the past century; scientists expect it to rise by an extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciers（冰川） melt, adding more water to the ocean. The warmer temperatures also make water expand, so it take up more space, causing the sea level to rise. The sea level has risen about 10-25cm in the last 100 years.
People have been increasing the greenhouse gases in the atmosphere, such as CO2, through burning coal, oil and gas. This adds to the power of the greenhouse effect, making the planet even warmer.
Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one metre this century.
Should this come true, millions of homes would be swallowed up by the sea and the world will be flooded with" climate refugees" looking for somewhere else to live.
【小题1】We can infer from Paragraph 2 that .

A．Tuvalu is in danger of being swallowed up by the sea

B．all Tuvalu islands are about five meters above the sea level

C．drinking water in Tuvalu has been destroyed

D．Tuvalu is often flooded by storms and waves

A．it is first places sinking into the sea

B．it is sinking into the mud where they stand

C．it will disappear in the future

D．its trouble is caused by global warming

　　BANGKOK－The tiny island nation of Tuvalu has promised to do its part for climate change by fueling its economy entirely from renewable sources by 2020．

　　The South Pacific nation of 12,000 people is part of a movement of countries and cities committed to going climate neutral．Since February 2008, 10 nations have promised to reduce their emission(释放)of greenhouse gases as part of a goal of reaching zero emissions in the next decade．

　　None of these commitments alone is expected to make a significant difference in the fight to cut heat-trapping gases．But the moves can inspire bigger emitters(排放者)like the United States to take further steps to limit their carbon footprints．

　　Climate scientists have urged rich countries to reduce emissions from 2005 levels by between 25 percent and 40 percent by 2020 to avoid the worst effect of warming．For its parts, Tuvalu hopes to replace the fossil fuels that are imported by ship with solar energy and wind power soon．

　　Tuvalu already emits almost no greenhouse gases．But because of climate change, many South Pacific islands see worsening flooding．The country is just 10 square miles in size, with most of its land less than a meter above sea level．

　　So far, Tuvalu has installed(安装)a 40-kiliowatt solar energy system with the help of Japan's Kansai Electric Power Co．and Tokyo Electric Power Company．The Tuvalu government is working to expand the ＄410,000 project from 40 to 60 kilowatts, and will extend solar power to outer islands．

　　“We thank those countries who are helping Tuvalu reduce its carbon footprint,”Public Utilities and Industries Minister Kausea Natano said．“And we look forward to the day when our nation offers an example to all-powered entirely by natural resources such as the sun and the wind．”

(2)

What is the main energy source in Tuvalu at present?
[　　]
A．	Solar energy
B．	Wind powder
C．	Imported fossil fuels
D．	Local fossil fuels

(3)

For Tuvalu, the biggest trouble now is that ________．
[　　]
A．	it lacks clean power equipment
B．	it lacks enough natural resources
C．	Climate change affects its economy
D．	it is under threat from rising sea level

(4)

What can we learn from the passage?
[　　]
A．	It is impossible for Tuvalu to realize its goal．
B．	The world will see zero emissions in ten years
C．	Tuvalu imports technology to reduce emissions．
D．	Big countries haven't started to reduce emissions．

(5)

The best title for the passage might be“________”．
[　　]
A．	Climate change threatens small island nations
B．	An island nation will only use green power
C．	Countries unite to reduce greenhouse gases
D．	island nations urge big countries to reduce emissions

Read the following passage．Answer the questions according to the information given in the passage and the required words limit．

　　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 which 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(导致温室效应的气体排放),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”．
