  1. [A] denied [B] conduced [C] doubled [D] ensured
、【答案】B concluded
  【解析】 题干中,一系列的研究已经_____,事实上,正常体重的人的患病风险要高于超重的人。根据句义,后面的部分实际上是研究的结论,因此concluded 符合题意,其他选项denied(否认)与意义相反,doubled(翻倍)与题意较远,ensured(确保)不符合题意,因为研究不能确保后面的事 实,只能得出后面的事实作为结论。所以正确答案为B。
  2. [A] protective [B] dangerous [C] sufficient [D]troublesome
、【答案】A protective
  【解析】 题干中,对于某些健康情况,超重事实上是有_____。根据前文研究的结论,超重能减少罹患疾病的风险,说明超重具有一定的保护作用。Dangerous 和文章意思相反,sufficient表示充足,troublesome表示有麻烦,不符合题意,所以正确答案为A。
  3. [A] Instead [B] However [C] Likewise [D] Therefore
、【答案】C likewise
  【解析】第三句话中,较重的女人患缺钙的比例低于较瘦的女人。_____,在老年人中,一定程度上超重……。需要填入的是和前半句表示顺接的词 语。A选项instead表示逆接的句意关系,B选项however也表示逆接,D选项therefore表示因此,只有C选项likewise意为同样 地;也,而且。因此正确答案为C。
  4. [A] indicator [B] objective [C] origin [D] example
、【答案】A indicator
  【解析】本句话中,_____,一定程度上超重,经常是健康的_____。A选项,表示指示器,指标。B选项objective表示客观;C选 项origin表示来源,D选项example表示例子。根据前面的文章内容,已经明确指出超重代表了健康,因此超重是健康的指标。因此正确答案为A。
  5. [A] impact [B] relevance [C] assistance [D] concern
、【答案】D concern
  【解析】本句话的句意是,需要更加_____是,很难对肥胖加以定义。A、impact(印象);B、relevance(相关性);C、 assistance(辅助);D、concern(关注)。前文已经说到肥胖事实上有利健康,但是又面临一个问题,到底如何去定义肥胖,因此需要更加关 注的是对肥的定义,其他选项均不符合题意,所以正确答案为D。
  6. [A] in terms of [B] in case of [C] in favor of [D] in of
、【答案】A in terms of
  【解析】题干中,肥胖经常______体质指数,或称为BMI来定义。A、in terms of ,根据……,就……而言。B、In case of 表示在某种情况下, C、in favor of 表示赞成,以……来取代,D、in respect of,关于……。因此正确答案为A。在医学研究和临床测试中经常使用BMI作为衡量受试者健康的重要指标,希望考生能够记住这一背景知识,方便日后做题。
