1．The price of gold has jumped to ________ new alltime high as debt worries in the US and ________ Europe continue to trouble the world.
A．the; / B．the; the
C．a; / D．a; the
解析：选C 句意：因美国和欧洲的债务忧虑继续困扰世界，黄金的价格跃升到一个新的历史高点。不定冠词a表示泛指，欧洲的前面不用冠词。故选C项。
2．The air in Beijing those days was difficult for people ________. As a result, lots of people had to stay at home, especially the old.
A．breathing B．being breathed
C．to breathe D．to be breathed
解析：选C 考查非谓语动词。句意：那些日子北京的空气让人很难呼吸。结果，很多人不得不待在家里，尤其是老人。the air与breathe之间构成逻辑上的被动关系，需用被动语态，但因句中有形容词difficult，不定式在作状语时，用其主动形式表达被动含义，故答案为C。
3．Believe it or not, your ship isn't quite sunk, as there are some ways to ________ a new career even if it's something you've never done before.
A．burst into B．get through
C．break into D．comb through
解析：选C 句意：信不信由你，你的船还没有完全沉没(还没有完全失去希望)，因为你还有办法从事一个新的事业，哪怕是你从来没做过的事情。burst into“突然闯入”；get through“通过，完成”；break into“闯入，进入，成功打入(某行业、某领域)”；comb through“梳理，搜索”。根据句意可知选C。
