14、这是一种特殊的灾难。因此本题应选择catastrophe(灾难)。luck“运气”；movement“运动”；existence“存在”。答案：A3.解析：由该段首句中的“The ice sheets in the poles .are melting”可知此处应选择melting，表示“假如冰盖真的融化了，那该怎么办？”。答案：D4解析：“据上周一发布的一项科学研究”。according to .“根据”，为固定搭配；look forward to“盼望着”；used to“过去常常”； see to“处理，照管”。答案：A5解析：renew“再生”；manage“设法”；await“等待”
15、；disappear“消失”。本文谈论冰盖融化，最后的结果应是北极冰盖的消失，应选disappear。答案：D6解析：从unless看出，此处是否定的假设。increase“增加”；reduce“减少”；die“死亡”；raise“抬起”。北极冰盖的消失应在二氧化碳排放量不能大幅度下降的前提下。答案：B7解析：size“大小，尺寸”；temperature“温度”；length“长度”；weight“重量”。由下文的“rise seven degrees centigrade”可知此处谈论的是温度。答案：B8解析：到2100年，北极有可能上升7摄氏度。special“特殊的”；normal“正
16、常的”； average“平均的”；abstract“抽象的”。此处表示北极温度正在以全球平均气温2倍的速度上升。答案：C9解析：介词by表示升降的程度。句意为：“冰盖融化将导致全球海平面上升1米”。答案：A10解析：force sb.to do sth.“逼迫某人做某事”。答案：C11解析：pattern“样品”；modal“形式”；style“风格”；example“例子，实例”。北极熊是可能在本世纪末灭绝的极地动物中的一个例子。答案：D12解析：从on the positive side看出，此处是转折关系。but表示转折关系；and表示并列关系；so表示因果关系；or表示逆向假设关系。
17、答案：A13解析：现在冰盖并没有完全融化，海平面正在逐渐上升，新的渔场、油气资源等的开辟还没有展开，因此应用一般将来时。答案：B14解析：发达国家正在进行另外一项实验。carry forward“发扬；推进；结转”；carry out“开展，实现”；carry on“继续开展”； carry about“随身携带”。答案：B15解析：sky“天空”；weather“天气”；climate“气候”；atmosphere“大气”。此处指长期的天气现象气候。答案：C16解析：accept“接受”；receive“收到”；get“得到”；push“推；按”。此处表示俄罗斯接受(签署)了京都议定书。答案
18、：A17解析：句意为：“而世界最大的污染国美国却拒绝加入该协议”。从but推断出美国和俄罗斯的行为是相反的。答案：B18解析：为削减全球6种温室气体的排放量，许多国家签署了京都议定书。2002年包括中国在内的104个国家接受了京都议定书。B、C两项意义相同，故排除；as well“也”，后不接宾语。故选D项。答案：D19解析：study“研究”；learning“学习”；knowledge“知识”；understanding“理解”。许多国家发起的应是对气候变化的研究。答案：A20解析：句意为：“全球近30%的二氧化碳排放量来源于美、加等发达国家”。who引导一个非限制性定语从句。从句中缺少主

27、11年4月22日，“我们”夫妻二人决定每天都追求一种绿色的生活方式，并且要坚持一整年。这意味着“我们”要做365件“绿色的”事情，这对“我们”来说是个挑战。最后，“绿色之年”改变了“我们”的思维，“我们”很感激有这个机会，也坚信“我们”确实有能力保护我们的地球。1解析：主旨大意题。概括文章大意可知，文章主要介绍了我们夫妻二人追求绿色生活方式的行为。在本文中going green为关键词，可概括文章主旨。B项概括范围过大；C项意为“保持思维开放”，曲解了文章主旨；D项意为“庆祝我们的绿色之年”，概括范围过小。答案：A2解析：推理判断题。根据第二段的最后两句可知，整整一年都要过绿色的生活，不是件容
28、易的事情，因为这不仅意味着要做365件不同的“绿色的”事情，还意味着除了一些简单的事情，我们还要不断地挑战自己，追求环保。这些都是不寻常的(unusual)环保任务，D项与之意思一致。文章并未提及其他几项内容。答案：D3解析：细节理解题。根据倒数第二段可知，在这一年里，我们完全改变了生活方式，做每一件事都追求环保、绿色，否则就要接受惩罚，所以A项正确。B项意为“他们无视他人不环保的行为”，与倒数第二段最后一句矛盾；C项意为“他们选择更好的化学清洁剂”，与倒数第二段的“Our home is kept clean by vinegar and lemon juice, with no chemical cleaners.”表达意思不一致；D项意为“他们出售自制的食品”，与倒数第二段的倒数第二句不一致。答案：A4解析：推理判断题。最后一段指出，我们的思维已经发生了变化，我们坚信自己有能力改变一些事情，保护我们的地球，由此可知，我们会继续自己的这种绿色生活方式。故B项正确。文章并未提到“政府会支持这个绿色计划”“有人和这对夫妻持有不同观点”或者“绿色之年正成为一项全国性活动”，故排除其余选项。答案：B
