A tiny clue found in ancient deposits has unlocked big secrets about Greenland39。s past and future climate. Just beyond the northwest edge of the vast Greenland Ice Sheet, researchers have discovered lake mud that have survived the last ice age. The mud, and remains of mon flies in it, record two interglacial periods(間冰期)in northwest Greenland. Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. As far as we know, it has never been found in Greenland. We think this is the first time anyone has reported it in ancient deposits or modern lakes there, Axford said. We were really surprised to see how far north it migrated (遷徙). This new information could help researchers better measure Greenland39。s sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. Those models could then improve predictions of how Greenland39。s ice sheet might respond to manmade global warming. After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world, said Yarrow Axford, an associate professor in the team. One of the big uncertainties in climate science is how fast the Earth changes when it gets warmer. Geology gives us an opportunity to see what happened when the Earth was warmer than today, said Axford. People might be surprised to see how today39。s Greenland looked during the last two interglacial periods. During the Last Interglacial, global sea levels increased by 15 to 30 feet, largely due to thinning of Greenland and Antarctica39。s ice sheets. However, now researchers believe northern Greenland39。s ice sheet experienced stronger warming than previously thought, which could mean that Greenland is more responsible for that sealevel rise. Finding lake deposits older than about 10,000 years, however, has been historically very difficult in Greenland. To measure these ancient temperatures, researchers look to ice cores (冰核) and lake deposits. Since ice and lake deposits form by a gradual buildup on annual layers of snow or mud, these cores contain history of the past. By looking through the layers, researchers can obtain climate clues from centuries ago.（1）Why are the remains of flies mentioned in the first two paragraphs? serve as evidence that there is still life in the Northwest Greenland. were one of the many ancient lives that were left in the Greenland mud. are indicators that Greenland was much warmer than previously thought. help the researchers realize that there was once a warm period in the Arctic.（2）The new information about Greenland is important because______________. have no idea how to measure Greenland39。s warming speed can help researchers better predict Greenland39。s response to warming should be more sensitive to the changes in the ice in Greenland is uncertain how fast the Earth changes with manmade global warming（3）Which of the following can be inferred from the passage? is easier for today39。s scientists to find ancient lake deposits. are surprised at the landscape feature of Greenland today. measure the changing temperatures by directly examining mud. holds enough ice that might one day threaten life in coastal cities.（4）Which do you think is the best title of the passage?
