9、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 Dtroublesome、【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.

10、【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.

12、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。7.

13、I_体重除以身高的平方，这里是用文字叙述了BMI指数得出的方法，也就是一个数学公式，所以equal符合题 意。A measure(测量)、B determine表示确定;D modify(修订)。句义就是BMI等于体重除以身高的平方。8.

15、straightforward表示直截了当，符合题意，因此正确答案为D。?10. A so B unlike C since D unless【答案】B while【解析】本句中，一些人有很高的BMI，实际上身材正好，_其他人有较低的BMI指数，可能_。从前半句我们可以看出，有些人 的BMI指数很高，应该属于体重肥胖的人，事实上身材正好，这里说明的是反常的现象，后半句是其他人的BMI指数较低，而_较差。A、so(所 以);B、while(而);C、since(因为);D、unless(除非)四个选项中只有while有转折的含义，其他选项均不符合题意，所以正确 答案为B。11.
