(1)The word "addiction" usually makes you think of alcohol or drugs, but in modem-day society we are seeing some new kinds of addictions. Some people are compulsive(难以自制的)shoppers. Others find it impossible to pull themselves away from their work. Still others spend countless hours watching TV or playing computer games.

(2)Over the years, shopping has become a very common activity. Many people enjoy going to stores more and more every day, but it’s more than a common hobby for some of them. They have turned into shopaholics. They are people who simple enjoy shopping and walking around spending money without being able to stop doing it. They are hooked on shopping and usually buy things that they don’t need. Even though they don’t have enough money, they buy everything they want.

(3)The question is, why do they have this addiction There isn’t a specific answer. Some people go shopping when they are sad, worried, upset or lonely, and they want to feel better. They use this activity as a way to forget their problems. Shopaholics say that they feel more important and better after they buy something. They also tend to have this addiction when they feel guilty.

(4)Shopaholism seems to be a harmless addiction, but it can ______. Some of them can be psychological. If this is the case, people addicted to shopping should go to a support group to help them break this habit. However, the process, like for most addictions, is long, and they suffer a lot. It can also cause financial problems. They just think about satisfying their feelings, so they spend money they don’t have. They get deep in debt, and they can even go bankrupt and get sent to prison.

Which sentence in the text is the closest in meaning to the following one Accordingly, these shopaholics should turn to a certain organization for help so that they can stop compulsive shopping.
