7．Most researchers remain confident that elevating high density lipoproteins levels by one means or another is one of the best routes for helping heart disease patients．But HDLs are complex and not entirely understood．One approved drug，called niacin，is known to both raise HDL and reduce cardiovascular risk but also causes an unpleasant sensation of heat and tingling．Researchers are exploring whether they can bypass this side effect and whether niacin can lower disease risk more than statinsalone．Scientists are also working on several other means to bump up high-density lipoproteins by，for example，introducing synthetic HDLs．"The only thing we know is dead in the water is torcetrapib，not the whole idea of raising HDL，" says Michael Miller，director of preventive cardiology at the University of Maryland Medical Center，Baltimore．

Suggested Answers and Explanations
1．vi
2．ii
3．vii 本段介绍了torcetrapib和statin的治病原理，但是同时短语“in contrast”与之前第二段后半段的内容呼应，暗示了这两种药在理论上能相辅相成，是理想的搭配。第一个选项无法涵盖整段意义，故选择i是错误的。
4．iii 本段分析了可能导致torcetrapibl临床试验失败的原因，后半段指出如果以上推测正确，那么未来的药物可借鉴这个试验，设法避免torcetrapib的缺陷，研制出有效的药物。viii选项无法涵盖后半段的意思。
5．ix 见首句。 |
