　　解析

　　1. C。题意为“大家都知道这个谚语‘你可以从他所交往的人来了解一个人的人品’”。company“交往的人，同伴，交际”符合题意，另外，keep company with“与…交往;与…打交道”是惯用词组，A、B、D均不能体现这层含义。

　　2. C。principal负责人，资本;principle原则，规则，规范;essential要素，要点，必需品;potential潜力，潜势。句意为“他制定了一个规则，每月存一些钱以备不时之需”，故选B。

　　3. D。根据语境：你开车太快，你没有注意到沿着路有一个时速40英里的时速限制么?range “范围，区域”;border“边界”;enquiry“询问”;limit“限制”。其中“a speed limit of ...miles per hour”是习惯表达。

　　4. C。题意为“这才是对年轻人的爱护和真诚的引导”。real真的，真实的;careful细心的;genuine真诚的，真心的;leading重要的，首要的。

　　5. B。题意为“我从不责备失败 — 生活中复杂的情况实在太多，但对于不努力，我绝不宽恕”。approximately近似地，大约;absolutely绝对地，完全地;hardly几乎不;desperately绝望地;B符合题意。

　　6. C。根据让步从句“尽管它们是双胞胎”可以猜出露西在长相上与她妹妹凯特完全不同，这样句意才能在逻辑上一致，否则不能用“虽然，尽管”，故答案选C。

　　7. D。根据答语“Well, yes. Quite a lot,”可得出答案actually“真实地、实际地、确实地”。gradually逐步地，渐渐地;entirely全部地，完整地;frequently频繁地，屡次地。

　　8. C。根据but I’m not sure可断定50,000 pounds这个数字并不准确，只能是roughly“粗略地、大体上地”。exactly精确地;totally整个地，完全地;previously事先地。

　　9. A。根据题意可知，雇员们提出的是能够帮助提高产品质量的积极的建议。positive“积极的”符合句意。cautious谨慎的;optimistic乐观的;accurate精确的。

　　10. C。根据题干前后两句话的关系可以断定是“因果”，故选Therefore“因此”，而A、B、D均表“转折关系”。
