    、【答案】B concluded
      【解析】 題干中,一系列的研究已經_____,事實上,正常體重的人的患病風險要高于超重的人。根據句義,后面的部分實際上是研究的結論,因此concluded 符合題意,其他選項denied(否認)與意義相反,doubled(翻倍)與題意較遠,ensured(確保)不符合題意,因為研究不能確保后面的事 實,只能得出后面的事實作為結論。所以正確答案為B。
      2. [A] protective [B] dangerous [C] sufficient [D]troublesome
    、【答案】A protective
      【解析】 題干中,對于某些健康情況,超重事實上是有_____。根據前文研究的結論,超重能減少罹患疾病的風險,說明超重具有一定的保護作用。Dangerous 和文章意思相反,sufficient表示充足,troublesome表示有麻煩,不符合題意,所以正確答案為A。
      3. [A] Instead [B] However [C] Likewise [D] Therefore
    、【答案】C likewise
      【解析】第三句話中,較重的女人患缺鈣的比例低于較瘦的女人。_____,在老年人中,一定程度上超重……。需要填入的是和前半句表示順接的詞 語。A選項instead表示逆接的句意關系,B選項however也表示逆接,D選項therefore表示因此,只有C選項likewise意為同樣 地;也,而且。因此正確答案為C。
      4. [A] indicator [B] objective [C] origin [D] example
    、【答案】A indicator
      【解析】本句話中,_____,一定程度上超重,經常是健康的_____。A選項,表示指示器,指標。B選項objective表示客觀;C選 項origin表示來源,D選項example表示例子。根據前面的文章內容,已經明確指出超重代表了健康,因此超重是健康的指標。因此正確答案為A。
      5. [A] impact [B] relevance [C] assistance [D] concern
    、【答案】D concern
      【解析】本句話的句意是,需要更加_____是,很難對肥胖加以定義。A、impact(印象);B、relevance(相關性);C、 assistance(輔助);D、concern(關注)。前文已經說到肥胖事實上有利健康,但是又面臨一個問題,到底如何去定義肥胖,因此需要更加關 注的是對肥的定義,其他選項均不符合題意,所以正確答案為D。
