Nevertheless, most doctors believe that reducing blood-fat levels is an effective way of preventing acute W. Which one of the following, if true, does most to justify this apparently paradoxical belief? (A) The blood level of fat for patients who have been cured of W is on average the same as that for the population at large. (B) Several of the symptoms characteristic of acute W have been produced in laboratory animals fed large doses of a synthetic fat substitute, though acute W itself has not been produced in this way. (C) The progression from latent to acute W can occur only when the agent that causes acute W absorbs large quantities of fat from the patient’s blood. (D) The levels of fat in the blood of patients who have disease W respond abnormally slowly to changes in dietary intake of fat.（C） (E) High levels of fat in the blood are indicative of several diseases that are just as serious as W. 我觉得D选项很好啊，C里那个agent莫名其妙哇~~作者: judydongxueni 时间: 2010-9-13 21:00
