14、mining the chemistry of the iron structure in these rocks，the researchers were able to work out the approximate amount of oxygen in the oceans around 700 million years ago and better understand the effects this would have had on all oxygendependent life in oceans.“The evidence suggests that although

15、 much of the oceans during the deep freeze would have been impossible to live in due to a lack of oxygen，in areas where the ice sheet begins to float there is a good supply of meltwater (融水) with oxygen.With the ice sheet beginning to melt，the air bubbles in it are released into the water，giving the

16、 ocean oxygen.We call this phenomenon aglacial (冰川的) oxygen pump ，” says Maxwell Lechte，a researcher in the Department of Earth and Planetary Sciences at McGill University.Around 700 million years ago，the Earth experienced the most severe ice age of its history，threatening the survival of most of th

21、对所有依赖氧气的海洋生物产生的影响。由此可知，研究人员研究分析了富含铁的岩石，才了解了7亿年前的海洋生物。故选C。答案：C2What creates a “glacial oxygen pump” according to Maxwell Lechte?AOxygen in meltwater.BIce sheets floating in the oceans.CA lack of oxygen in the ocean.DA good supply of air above ice sheets.解析：推理判断题。根据第三段的“.the ice sheet begins to float

22、there is a good supply of meltwater with oxygen.With the ice sheet beginning to melt，the air bubbles in it are released into the water，giving the ocean oxygen.We call this phenomenon a glacial oxygen pump”可知，“glacial oxygen pump”这种现象是由冰融水中的氧气引起的。故选A。答案：A3What might the researchers continue to study

23、in the future?AThe present food web.BDiverse forms of animals.CEvolution of complex animals.DModern ice environments.解析：推理判断题。根据最后一段最后一句“The researchers plan to explore how these environments might have kept a food web by looking at todays similar environments that host complex ecosystems.”可知，研究人员计划

24、通过研究当今承载着多元生态系统的相似环境来探索这些环境是如何维持食物链的，similar environments指的是与上文提到的severe conditions of the ice age相似的环境，故可推知，研究人员接下来要研究现代的冰环境。答案：D4What is the best title for the text?ANewly Discovered Ironrich RocksBLife Evidence Found in Melting Ice SheetsCSecret of How Animals Survived Ice AgeDThe Importance of O

25、xygen in the Oceans解析：标题归纳题。通读全文可知，本文主要讲述的是研究人员通过分析富含铁的岩石，了解冰河时期的环境条件，知晓在冰河时期生命是如何生存下来的，因此选项C正确。答案：C.短文改错Dear Jim，How is everything going?
