Unit 3 Protecting ourselves

Ⅰ. 细品味经典文章

pared with food that provides nutritional support, a drug is any substance that causes a physiological change in human beings’ body when inhaled or injected, such as morphine, heroin, cannabis and so on.

The dru g problem is a worldwide problem, in the 20th century, the world’s most serious public hazard and one of the public enemies of all mankind, which currently continues to threaten public health, safety, wellbeing and to undermine social, economic and political stability and sustainable development.

How does a drug undermine a single one, and then most of us, finally the social, economic and political stability step by step? Have you ever heard “butterfly effect”? It may precisely elucidate the pot ential process.

We’ve already realized that a drug will cause a physiological change in a human being’s body, making you both physically and mentally dependent on it. When not used, a drug causes a lot of disorders in your physiological functions, leaving you less than alive. And furthermore, more and more drugs should be used to prevent addicts from suffering from pains.

The more drugs used, the more cost. How can a mon addict afford so much? So he or she turns to their family for help or imposes the burden on their family. It is not that their family are not willing to help them, but that such an abyss is beyond their abilities. By sacrificing more people, the criminals or profiteers spread the drugs worldwide to make huge profits.

Gradually, destroying addicts’ families, drugs exhaust what they have. If allowing such a situation to indulge itself, a government may also fail. In order to stop, confine and prevent this situation, many a countermeasure is being carried out with efforts from multiple sections or countries.

We should never ever contact drugs no matter how curious you are or how seductive the drug is. Cherish life, keep away from drugs.
