According to a recent report by the UNEP, if car numbers keep increasing at the present rate, there will be more than a billion on the road by 2025. Today, motor vehicles put out 900 million tones of carbon dioxide a year--about 15 percent of our total output. More vehicles will mean more global warming. Also by 2025, two-thirds of the world’s people will live in cities, so traffic jams and pollution will loom large in most people’s lives.
We live in a society in which the medicinal and social use of substances is pervasive: an aspirin to quiet a headache, some wine to be sociable, coffee to refresh oneself in the morning. When do these socially acceptable and apparently constructive uses of a substance become misuses? Most substances taken in excessively will produce negative effects such as poisoning. Repeated use of a substance can also lead to addiction or substance dependence. Dependence is marked first by an increased tolerance, and then by the appearance of withdrawal symptoms when the substance is discontinued.
选项
答案
我们居住在一个物质的药用和社会使用泛滥的社会里:一片阿司匹林用来减轻头痛,一些葡萄酒用于交际,咖啡在早晨可以提神,何时这些社交上被接受而显然也是有益的物质使用变成滥用了呢?大多数物质过多摄入后会产生诸如中毒等的负面影响。对于某种物质的重复使用同样能导致上瘾或者是物质依赖性。依赖性首先表现为增加最大用量,后来,当物质不再提供的时候,会表现出断瘾反应。
