高二英语单项填空简单题查看答案及解析
Tuvalu, a tiny country in the Pacific Ocean, has asked for help as it fears it will be swallowed up by the sea.
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. 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 24 cm over the past 100 years. Experts say that it will have sunk another 24 cm by 2050. A century ago, St. Mark's Square, the lowest point in the city, flooded about nine times a year. Nowadays, 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 degrees over the past century, scientists expect it to rise by 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 takes up more space, causing the sea level to rise. The sea level has risen 10.25 cm in the last 100 years.
The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. 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 meter this century.
Should this come true, the sea will swallow up millions of homes and the world will be flooded with "climate refugees" looking for somewhere to live.
1. We can infer from the second paragraph that .
A. Tuvalu is in danger of being swallowed up by the sea
B. all Tuvalu's islands are about five metres above the sea level
C. drinking water in Tuvalu has been destroyed
D. Tuvalu is often flooded by storms and waves
2.The author uses Tuvalu and Venice as examples in order to explain .
A. they are the first places sinking into the sea
B. they are both sinking into the mud where they stand
C. they will disappear in the future
D. their trouble is caused by global warming
3.What does "climate refugees" mean?
A. People who are forced away from their homeland by climate.
B. Climate changes.
C. Rare animals.
D. Climate effect.
4.Which of the following is NOT true according to the passage?
A. Tuvalu's nine little islands are less than five meters above the sea level.
B. The average global temperature has risen by 13 centigrade degrees over the past 100 years.
C. The warmer temperature causes the sea level to rise.
D. There will be huge climate changes unless the warming is stopped.

Japan is an island country in the Pacific Ocean. As the Japanese students already know, four main islands and more than 3,000 small ones stretch from north to south for about 1,300 miles. As for the climate of the country, well, it’s hot and humid(潮湿) in summer, but it is quite cold and wet in Japan during winter. Typhoons, which are violent tropical storms, often threaten Japan during the fall. That’s, of course, during the harvest season.
