9、gthatitrepresentsourgreatestnationalsecuritythreat.1.[A]denied[B]conduced[C]doubled[D]ensured、【答案】Bconcluded【解析】題干中，一系列的研究已經(jīng)_____，事實(shí)上，正常體重的人的患病風(fēng)險(xiǎn)要高于超重的人。根據(jù)句義，后面的部分實(shí)際上是研究的結(jié)論，因此concluded符合題意，其【解析】題干中肥胖經(jīng)常______體質(zhì)指數(shù)，或稱為BMI來定

10、義。A、intermsof，根據(jù)……，就……而言。B、Incaseof表示在某種情況下，C、infavof表示贊成，以……來取代，D、inrespectof，關(guān)于……。因此正確答案為A。在醫(yī)學(xué)研究和臨床測(cè)試中經(jīng)常使用BMI作為衡量受試者健康的重要指標(biāo)，希望考生能夠記住這一背景知識(shí)，方便日后做題。7.[A]measures[B]determines[C]equals[D]modifies、【答案】Cequals【解析】本題題干中BMI__

11、___體重除以身高的平方，這里是用文字?jǐn)⑹隽薆MI指數(shù)得出的方法，也就是一個(gè)數(shù)學(xué)公式，所以equal符合題意。Ameasure(測(cè)量)、Bdetermine表示確定Dmodify(修訂)。句義就是BMI等于體重除以身高的平方。8.[A]inessence[B]incontrast[C]inturn[D]inpart、【答案】Cinturn【解析】本題題干中，肥胖_____能夠分成中度肥胖、重度肥胖和極度肥胖。A、inessence(事實(shí)

12、上、實(shí)際上)B、incontrast(相反地)C、inturn(依次)D、inpart(部分地)。本句是將肥胖依次分級(jí)，所以正確答案為C。9.[A]complicated[B]conservative[C]variable[D]straightfward、【答案】Dstraightfward【解析】題干中，相比之下，這樣的數(shù)字標(biāo)準(zhǔn)看起來_____，實(shí)際上不是的。A、complicated(復(fù)雜)B、conservative(保守)、C、

13、variable(可變的)D、straightfward(直截了當(dāng))這里的數(shù)字標(biāo)準(zhǔn)指的就是肥胖指數(shù)，肥胖指數(shù)分為三類，而且算法比較簡(jiǎn)單，所以A復(fù)雜不正確，B選項(xiàng)保守，用于描述一種數(shù)學(xué)公式，不恰當(dāng)，一名患者或一名受試者的BMI一般是確定的，因此可變的也不符合題意，D選項(xiàng)straightfward表示直截了當(dāng)，符合題意，因此正確答案為D。10.[A]so[B]unlike[C]since[D]unless【答案】Bwhile【解析】本句中，
