59. “Substance abuse” (Line 5, Paragraph 1) is preferable to “drug abuse” in that _____.

　　[A] substances can alter our bodily or mental functioning if illegally used

　　[B] “drug abuse” is only related to a limited number of drug takers

　　[C] alcohol and tobacco are as fatal as heroin and cocaine

　　[D] many substances other than heroin or cocaine can also be poisonous

　　[答案] D

　　[解题思路]

　　第一段第三句至最后一句指出“They don’t realize that familiar substances such as alcohol and tobacco are also drugs. This is why the more neutral term substance is now used by many physicians and psychologists. The phrase “substance abuse” is often used instead of “drug abuse” to make clear that substances such as alcohol and tobacco can be just as harmfully misused as heroin and cocaine”(他们没有意识到诸如酒精、烟草这些我们熟悉的物质也都是药物。这也就是为什么现在许多医生和心理学家使用“物质”这个更加中性的词的原因。他们常用“物质滥用”而不用“药物滥用”来清楚表明滥用酒精、烟草这样的物质与滥用海洛因和可卡因一样有害)，因此用“Substance abuse”比“drug abuse”更好的原因在于如果人们也滥用酒精和烟草等物质，与毒品一样是有害的，因此D为正确选项。C选项的错误在于alcohol和tabacco只是例子，且文章没有提及它们是否fatal。而A和B选项都不符合题意。

　　[题目译文]

　　使用“物质滥用”(第一段第五行)这个词语比“药物滥用”更合适是因为 。

　　[A] 物质如果非常使用会改变我们的身体和心理机能

　　[B] “药物滥用”只与少数吸毒者有关

　　[C] 酒精和烟草与海洛因和可卡因具有一样的致命性

　　[D] 除了海洛因和可卡因之外，还有很多物质也有毒性
