1、阅读理解专练(七)(限时30分钟)AA tiny clue found in ancient deposits has unlocked big secrets about Greenlands 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 common flies in

Although researchers have long known these two periodsthe early Holocene and Last Interglacialexperienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. “As far as we know,
3、 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 (迁徙). ”This new information could help researchers better measure Greenlands sensitivity
4、to warming, by testing and improving models of climate and ice sheet behaviour. Those models could then improve predictions of how Greenlands ice sheet might respond to man-made global warming. After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of glo
5、bal 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 cha
6、nges 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 todays Greenland looked during the last two interglacial periods. During the Last Interglacial, global sea levels increased by 15 t
7、o 30 feet, largely due to thinning of Greenland and Antarcticas ice sheets. However, now researchers believe northern Greenlands ice sheet experienced stronger warming than previously thought, which could mean that Greenland is more responsible for that sea-level rise. Finding lake deposits older th
8、an 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 p

16、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. 可知格陵兰的冰盖变化会影响沿海城市的每一个人。 BHave you ever heard someone say “You totally look like youre a Jessica” or something similar? People seem to think that they kno
17、w what kind of person a “Jessica” or a “Michael” looks like. Why is this? According to a study published in the Journal of Personality and Social Psychology, humans tend to associate peoples names with their appearances, and can even guess someones name based on how they look. Researchers collected
18、thousands of photos of peoples faces. They labeled (贴标签于) each photo with four names. Then, they asked volunteers to guess which of the four names was correct. The volunteers were able to guess the right name 38% of the time. It seems that certain characteristics of faces give them clues about someo
19、nes name, Readers Digest reported. However, this only worked when the volunteers looked at names from their own culture. In addition, the volunteers were not as good at guessing the real names of people who used nicknames more often than their real names. This may show that a persons appearance is a
