阅读快车系列答案Since 1950, the amount of information about the nutrition of food has increased by nearly 900 percent. Besides this fact, obesity has risen by 214 percent and nearly two out of every three adults in America are overweight or obese. Being overweight is not only an appearance problem, and it also increases the risk of various diseases including diabetes, sleep disorder and cancer.
With so much nutritional knowledge easy to find, we cannot simply ignore our present obesity epidemic(流行病). We know that fruits and vegetables are rich in vitamin. Though we are overweight, many of us choose junk food over healthy food out of habits. One explanation for our strong desire for junk food is that we learn to connect junk food with positive feelings when we are young, and changing this attitude requires a huge amount of confidence and determination. Fortunately, new research published in May 2012 has shown a simple and accessible way to make healthier food choices- the one that doesn’t rely on great determination.
The research was based on two separate studies and it was carried out by T. Bettina Cornwell of the University of Oregon and Anna R. McAlister of Michigan State University. In the first study, 60 adults between the ages of 19 and 23 were questioned about the role of food and drinks. The survey tells us that adults prefer sweetened drinks with high-calorie, salty foods, to sweetened drinks with vegetables.
In the second study, 75 children between the ages of 3 and 5 were gathered for some experiments including drinks served with vegetables. The preschooler experiments were carried out under different situations and on different days. The researchers found that the children chose to take more green vegetables when they were served with water instead of a sweetened drink.
According to Cornwell, children learn to connect high calorie, sugary drinks such as cola, with high fat foods such as French fries, from a very early age. McAlister adds that early taste development appears to play an important role in food choices later in life. Meals served at home and meals offered at restaurants, set the stage for this idea and for the preference to choose junk food over healthy food, when beginning to take sweetened drinks.
“Our taste preferences are heavily influenced by regularly eating particular food and drinking particular drink,” states Cornwell. “If the drink on the table goes against both adults and children eating their vegetables, then perhaps it is time to change that drink… and to serve water with all meals. Restaurants could easily use water as free drink for children’s meals and charge extra money for other drinks.” Both McAlister and Cornwell are confident that serving water with meals could effectively reduce the nation’s obesity rates, diabetes rates and ever rising healthcare costs.

In South Korea, children get used to the Internet at an early age. A survey last year by the Ministry of information and Communication showed that nearly half of children between the age of 3 and 5 use the internet.
“In south Korea, the Internet has become a babysitter, said Lee Kyong Ko, a professor at Duksing, Women’s University in Seoul.
Online role-playing games, where participants make friends and band together, have a strong appeal to Koreans,“One problem with those games is that you build your online person through countless hours of battles, and you develop a huge emotional attachment to your game character,”said Chang Woo Min, a one-time online gamer.
Parents report that their children steal money and do not come home for days and even weeks, practically living in Internet Cafes, and sometimes they refuse to look for jobs and play games all night and sleep during the day.
The authorities require Internet cafes to keep their distance from schools, and they open camps for teenage addicts and distribute booklets(小册子) on the dangers of game addiction. In addition, they are training hundreds of counselors, who visit schools and Internet Cafes.
In the 28,000 Internet Cafes in South Korea, persons under 18 are banded from entry after 10 p.m.. The authorities have even discussed reducing the points of gamers who play for more than three consecutive (连续的) hours, But such talks have produced no agreement, amid concerns that such restrictions would put a high-growth industry in danger and worse the problem of teenagers stealing adult online identification numbers,“Sooner or later we will be able to announce our measures,”the minister of Information and Communication, Rho Jun Hyoung, said at a news conference in May.“Since South Korea is one of the most active and developed countries in the Internet, the world is paying great attention to What policy we will adopt on this problem.”
