阅读理解 A new study shows one of the largest glaciers(冰川) in Greenland is becoming smaller and speeding tothe a faster than scientists expected. If it continues, Greenland itlf could become much smaller during this century and global as could ri as much as 3 feet. The rates of change that we're noticing are much higher than expected. If the rates continue, it is not likely that Greenland could shrink by veral tens of percent this century. However, it's not known how quickly this coastal respon of the Greenland ice sheet melting will have an effect on the vast inland ice. Greenland is the world's largest island, covering area more than three times the size of Texas. Some 81percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the a, its weight keeps it firmly resting on the bottom. A glacier's front is the pointwhere the water is deep enough that the glacier floats. Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over the past years, its trip to the a has sped up from about 70 feet per day to nearly 110. The melting is driven by a warmer climate. Temperatures in Greenland have rin more than five degrees Fahrenheit(华氏温度) in the last ten years. Since most of Greenland's ice is on land, as will rias the ice melts. If all Greenland's ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen any time soon.1. What can we know about the glaciers according to the passage?A. Glaciers only lie in Greenland.B. Water in glaciers is more than a water.C. Glaciers sometimes float on the water.D. Glaciers can increa the water level of lakes.2. According to the passage, we know that Greenland _____.A. belongs to Canada  B. is the largest island in North AmericaC. is all covered with glaciers   D. is sinking under the a level3. Which of the following may be the result of the disappearing of Greenland glaciers?A. The climate of the world will be warmer.B. The glaciers in other areas will be bigger.C.
