28、可知极地的冰原和高山的冰川正在融化。由此带来的后果应是地球面临着被洪水淹没(flooding)，而不是snowing(降雪)，watering(浇水)和raining(下雨)。答案：B2解析：地球面临着被淹没的危险，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：A 3.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”。acco
29、rding 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”；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“
30、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。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
