题文

阅读理解。 TUVALU, a tiny country in the Pacific Ocean, has asked for help as it fears it will be swallowed up by the a. Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than fivemetres above a level. Salt water is already entering the country's drinking water supply, as well as damagingplants 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 a. Venice, a historic city in Italy best known forits canals, has sunk about 24 cm 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 times a year. Nowadays, it happens more than 100 times a year. While Venice is slowly sinking into the mud on which it stands, Tuvalu's rising a level is caud by global warming. The average global temperature has incread by almost 0.5 centigrade degrees over the past century; scientists expect it to ri 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 takes up more space, causing the a level to ri. The a level has rin about 10-25 cm in the last 100 years. The main cau of global warming is human pollution. Through burning coal, oil and gas, people have beenincreasing the greenhou gas in the atmosphere, such as CO2. This adds to the power of the greenhou effect, making the planet even warmer. Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The a level could ri by one meter this century. Should this come true, the a 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 cond paragraph the _____. A. Tuvalu is in danger of being swallowed up by the a B. All Tuvalu's islands are about five meters above the a level C. Drinking water in Tuvalu has been destroyed D. Tuvalu is often flooded by storms and waves 2. The author us Tuvalu and Venice as examples in order to explain _____.A. they are the first places sinking into the a B. they are both sinking into the mud where they stand C. they will disappear in the future D. their trouble is caud by global warming3.

Which of the following is NOT true according to the passage? A. Tuvalu's nine islands are less than five meters above the a level.B.
