Section D
Directions: Read the passage carefully. Then answer the questions and complete the statements in the fewest possible words.
An addiction(瘾)is an activity or substance we are eager to experience repeatedly, and for which we are willing if necessary to pay a price. Common addictions involve alcohol, cigarettes, food, drugs, gambling, etc. This article discusses the concepts which can be helpful in coping with addictive behavior.
Relatively minor addictions, such as watching too much television, or lying in bed on weekend mornings, are often not even considered addictions, because the price paid for engaging in them is not high. On the other hand, we tend to use the term “addict” to describe the person who, at least in the eyes of others, continues to be addicted in a behavior long after it has become clear that the substantial price being paid was not worth the benefit. The individual who has lost career, house, family and friends because of cocaine (可卡因) use, but is unwilling to consider stopping is an unfortunate example.
Negative addictions range from those with very minor negative consequences, to those as serious as the cocaine addict just mentioned, with much area in between. Although it is not necessarily true that a negative addiction grows stronger over time, yet a constant level of addictive behavior (e.g., overspending $ 200 a week ) can lead to an increasing level of negative consequences.
You may be surprised to learn that addictions can also be considered positive. Positive addictions are those in which the benefits outweigh the price. A common example would be the habit of regular exercise. The price of membership in a gym, the time involved and any clothing expense is outweighed by the benefits of better health, energy, self-confidence and appearance. As with negative addictions, positive addictions may not get stronger over time, and there is a broad range of how much benefit is actually obtained.
What is common to both positive and negative addictions is the urge to engage in the addictive behavior, and the satisfaction that is felt when the urge is acted upon. The urge is a state of tension and expectation that is experienced uncomfortably as a desire for the substance or activity. Because we experience relief when the urge is acted upon, there is an increased likelihood that we will act on the urge again.
