【单选题】"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

网考网参考答案：D
网考网解析：
[详细解答] 文中第一段说到The phrase "substance abuse" is often used instead of "drug abuse" to make clear that sub stances such as alcohol and tobacco call be just as harmfully misused as heroin and cocaine．(他们常用“物质滥用”而不用“药物滥用”来清楚表明滥用酒精和烟草这样的物质同滥用海洛因和可卡因一样有害)，这与选项[D]“除了海洛因和可卡因外，许多其他物质也可能是有毒的”意思相近，其中“也可能是有毒的”暗指“如果不适量使用，也会造成毒性反应”，故[D]为正确答案。 查看试题解析出处>>
