five years，a woolly mammoth (猛犸象) will likely be cloned，according to scientists who have just recovered wellpreserved bone marrow (骨髄) in a mammoth bone.russian scientist semyon grigoriev and his colleagues are now analyzing the marrow，which they obtained from the mammoth，found in siberian soil.grigoriev and his team，along with colleagues from japan，have announced that they will start a joint research project aimed at recreating the enormous mammal，which went extinct around 10,000 years ago.mammoths used to be a common sight in north america and eurasia.many of our distant ancestors probably had regular facetoface encounters with the elephantlike giants.the key to cloning the woolly mammoth is to replace the nuclei of egg cells from an elephant with those extracted (提取) from the mammoths cells.doing this，according to the researchers，can result in embryos with the mammoths dna.that has actually been known for a while.what have been missing are the woolly mammoths nuclei with undamaged genes.scientists have been on a search for such nuclei since the late 1990s.now it sounds like the missing genes may have been found.in the course，global warming may be responsible for the breakthrough.warmer temperatures tied to global warming have melted ground in eastern russia that is almost always permanently frozen.as a result，researchers have found a fair number of wellpreserved frozen mammoths there，including the one that produced the bone marrow.is it such a good idea，however，to clone animals that have long been extinct？for a while there has been some discussion of a reallife jurassic park setup containing such animals.introducing these beasts into existing ecosystems could be like bringing in a potentially invasive species that would try to fill some space presently held by other animals.even if the cloned animals were contained in special parks，there could still be a risk of spreading.so if the woolly mammoth is successfully cloned sooner rather than later，wed probably be left with more questions and arguments than answers，at least in the short term.语篇解读猛犸象是一种早在1万年前已经绝迹了的动物，借助克隆技术，俄罗斯及日本的科学家们有望通过获取的冰冻在西伯利亚地下的猛犸象骨髓克隆出该动物。1which of the following would be the best title for the passage?ahow to clone a woolly mammothbthe woolly mammothan ancient speciescthe research made by russian and japanese scientistsda woolly mammoth to be cloned解析：主旨大意题。第一段within five years，a woolly mammoth will likely be cloned点明文章的主旨，并在后文具体讲解了克隆猛犸象的关键步骤及可能带来的问题。答案：d2which of the following can be the key factor in cloning a mammoth?ato find a living

temperatures enable scientists to find wellpreserved frozen mammothsdresearchers cant work efficiently if the weather is too cold解析：细节理解题。根据第五段可知全球变暖带来的气温升高使得俄罗斯东部常年处于冰冻状态的土地得以融化，从而研究人员在那里寻找到了保存完好的冰冻状态的猛犸象。因而c项正确。答案：c4which of the following best describes the writers attitude towards the future of cloning a mammoth?auncertain.bindifferent.cpositive.ddisappointed.解析：作者态度题。在最后两段中，作者提出了克隆猛犸象可能会产生的问题，对克隆猛犸象的未来抱一种不确定的态度。答案：athe world market for wind energy saw a sound revival in the first half of 2011 and regained momentum (动力) after a weak year in 2010.the worldwide wind capacity (风电装机容量) reached 215,000 mw by the end of june 2011，out of which about 18,400 mw were added in the first six months of 2011.this increase represents 15% more than in the first half of 2010.still the five leading countrieschina，usa，germany，spain and indiatogether represent a total share of 74% of the global wind capacity.again in 2011，china continues to dominate the world wind market，adding 8 gw in only 6 months.by june 2011，china had an overall capacity of around 52 gw.most of the european markets showed stronger growth in 2011 than in the previous year.the top markets in europe continue to be germany，spain，italy，france，the united kingdom and portugal.only france and denmark showed a decrease in their new installed capacity compared to the first half of 2010.the us market added 2,252 mw，about 90% more than in the same，but very weak period of 2010.however，it is questionable whether the us market can regain the strength it had in 2009 when a total capacity of almost 10 gw was installed within one year.whats more，during the first half of 2011，three countries were added to the list of countries using wind energy，increasing the number of wind energy markets from 83 to 86：venezuela，honduras，and ethiopia.the total installed wind capacity is projected to reach 240,500 mw by the end of 2011.this capacity can cover almost 3% of the electricity demand all over the world.语篇解读世界风电产业在经历了一年的低潮期后，在2011年上半年恢复了活力。5how much wind capacity was added in the first half of 2010?aabout 16,000 mw.babout
