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 ice sheets. However, now researchers believe northern Greenland39。 People might be surprised to see how today39。s sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. Those models could then improve predictions of how Greenland39。 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). A tiny clue found in ancient deposits has unlocked big secrets about Greenland39。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇環(huán)保類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，概括歸納，從而選出正確答案。根據(jù)第三段中的“A new environmentallyfriendly shopping model was recently launched at the World Economic Forum in Davos, Switzerland.”及全文內(nèi)容可知，文章主要介紹美國(guó)一家公司推出一種新的零浪費(fèi)購(gòu)物模式。故選D。 （3）考查細(xì)節(jié)理解。根據(jù)第四段中的“Szaky said that Loop is the future of shopping. But it es from an idea of the past.”和第五段“He pared it to the milkman model of the 1950s in the United States. Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste.”可知，Loop購(gòu)物模式的想法來自于過去送奶工模式，是一種可以杜絕零浪費(fèi)的模式。故選A。根據(jù)第二段“The world39。The concerns of future shopping.【答案】 （1）A（2）C（3）D（4）A 【解析】【分析】本文是一篇說明文，介紹美國(guó)一家公司推出一種新的零浪費(fèi)購(gòu)物模式。The world39。B.A new shopping model.D.Switzerland and Britain.C.The milkman model.（3）Which countries is Loop expected to expand to by 2020?

Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste. Now, that may be changing. A new environmentallyfriendly shopping model was recently launched at the World Economic Forum in Davos, Switzerland. This shopping model, called Loop, aims to replace throwaway containers with reusable ones.
