　　Suggested Answers and Explanations

　　1.vi

　　2.ii

　　3.vii 本段介紹了torcetrapib和statin的治病原理，但是同時(shí)短語“in contrast”與之前第二段后半段的內(nèi)容呼應(yīng)，暗示了這兩種藥在理論上能相輔相成，是理想的搭配。第一個(gè)選項(xiàng)無法涵蓋整段意義，故選擇i是錯(cuò)誤的。

　　4.iii 本段分析了可能導(dǎo)致torcetrapibl臨床試驗(yàn)失敗的原因，后半段指出如果以上推測正確，那么未來的藥物可借鑒這個(gè)試驗(yàn)，設(shè)法避免torcetrapib的缺陷，研制出有效的藥物。viii選項(xiàng)無法涵蓋后半段的意思。

　　5.ix 見首句。

　　6.v

　　7.A 見第二段。題目中administer一詞意為“用藥”，subject一詞為“實(shí)驗(yàn)對象”之意。

　　8.B 見第四段“... to raise levels of HDLs，which ferry cholesterol out of artery-clogging plaques to the liver for removal from the body.”即HDLs的作用最終是將choleserol清除出人體：“... for removal from the body”。

　　9.B 見第四段“But HDLs are complex and not entirely understood.”

　　10.C 見第二段“... plus a cholesterol-lowering statin”，即statin是可以降低cholesterol的。

　　11.D 見第六段“So inhibiting CETP，... might actually cause an abnormal and irreversible accumulation of cholesterol in the body.

　　12.A 見第三段。

　　13.C 見第四段“Statins，in contrast，mainly work by lowering the 'bad' low-density lipoproteins.”
