21. Companies are hiring more foreign employees because ________.
　　A) they find foreign employees are usually more talented
　　B) they need original ideas from employees hired overseas
　　C) they want to expand their business beyond home borders
　　D) they have difficulty finding qualified personnel at home(D)

　　题目问公司雇佣越来越多的外国员工的原因是什么。
　　文章第一段称跨国求职因“chronic personnel shortages that are causing companies to search beyond their home borders for talent”而更加火热。chronic personnel shortages是长期人事短缺的意思，后面的that替代shortages，句子可以转换为personnel shortages are causing companies to search beyond their home borders for talent，意思是人事短缺正在迫使公司跨越国界需要人才。可见公司雇佣越来越多的外国员工的原因是长期人事短缺。

　　A，他们发现外国员工通常更具才华。
　　B，他们需要海外员工的新颖思维。
　　C，他们想把业务拓展到国外。
　　D，他们在国内发掘合格人才较为困难。

　　只有D符合文意。

　　22. The author believes that an individual who applies to work overseas ________.
　　A) is usually creative and full of initiative
　　B) aims to improve his foreign language skills
　　C) is dissatisfied with his own life at home
　　D) seeks either his own or his children’s development(D)
　　题目问作者认为一个人申请海外职位如何如何。
　　文章第一段只有一句话，讲的是跨国求职猛增的事实，这里题目问的必然是海外求职的细节问题，第一段不会提供答案，应该去第二段寻找相应内容。第二段从求职者的角度介绍了海外求职的几点原因。此题可以结合选项使用排除法。
　　A，海外求职者往往创造性强、充满进取心。这句话是不对的，句中提到creative和initiative是在第二段作者指出求职火热的第二个原因之时：They may want a position with more responsibility that encourages creativity and initiative。这句话的意思是他们需要一个职位，这个职位with more responsibility，即需要承担更多的责任，that 指代responsibility，encourages creativity and initiative——激发创造力和进取心。从这句话可知海外求职者认为为外国公司工作可以激发自己的创造性和进取心，而不是像A所说的海外求职者往往创造性强、充满进取心。
　　B，海外求职的目的是提高自己的外语水平。第二段最后一句话讲到了提高外语水平：they may wish to expose their children to another culture, and the opportunity to learn a second language。opportunity to learn a second language即是学习第二语言的机会。但这里的“机会”应该与前文的“to”连接，完整句子是they may wish to expose their children to the opportunity to learn a second language，他们希望带给孩子学习外语的机会。
