A four-year study of 200 college students found that those who drink heavily and started drinking at an early age demonstrate poor decision-making skills, just like long-term, chronic(长期的) alcoholics. Researchers at the University of Missouri-Columbia believe early onset binge drinking negatively affects psychological development.
The researches examined college students between the ages of 18 and 22. After three years, they tested them using the Iowa Gambling Test, which measures the tendency to make immediate (disadvantageous) or long-term (advantageous) choices.
Based on the students’ reported drinking habits, they were grouped into four categories: low binge drinkers, moderate binge drinkers, increasing binge drinkers and stable or high binge drinkers.
“Students in the stable or high alcohol use category, who had longer histories of binge drinking, made riskier and less advantageous choices, which reflect problems associated with planning for the future,” the researchers reported.
The study also found that only students who started binge drinking when they were younger showed impairment on the task.
“There is reason to think that heavy binge drinking during adolescence, when the brain is still rapidly developing, may have some negative legacy (遗传) on psychological development,” said Kenneth J. Sher of MU’s Midwest Alcoholism Research Center in a news release. “The interesting thing is that if we were to just look at binge drinkers and how impaired they are in the decision-making process as juniors, we’d really be obscuring(使模糊) the important issue, which is how long they’ve been binge drinkers and / or how early they started.”

Restoring the quakehit ecosystems is a question of balancing the interests of the local people and the environment. Rural methane (沼气) projects can reduce the number of locals taking firewood from the mountainsides. The use of straw as food for animals will ensure that vegetation(草木) can grow. In Sihai township and Dazhuangke village, in Beijing, they now have a forestry coverage of 85% or more, compared to the 30% they had 15 years ago. Back then, land was used very inefficiently: one person would use 20 mu of forest just for firewood. With those pressures on the ecosystem, no amount of spending on reforestation will succeed. Then the government relocated the population and paid those who remained to tend the forest and provide coal. This reduced the pressures on the ecosystem and it was able to recover naturally.
When an ecosystem has not been pushed past certain limits, it is able to recover on its own. Human involvement should only play a minor role, including after an earthquake. This is particularly the case for sandy grasslands, grasslands deserts, the mountains of the south and the northern sides of mountains in the north. In these areas soil remains and the water, light, heat and nutrients needed are available. Less human involvement is even more appropriate in areas with a small population, where it can avoid money being wasted on ineffective efforts, such as creating forests in dry areas.
The creation of nature reserves should be a model to allow damaged ecosystems to recover. Funding can start at the national level; centrallyfunded nature reserves can enforce environmental protection laws and help to promote the local economy. This will solve the problems of reserves being run to make money. When national reserves are funded, local governments will be able to adopt the same model and provide the funds for nature reserves from their own budgets. The first project should be established in nature reserves hit by the quake; these can then become models for other areas.
1.To restore the quakehit ecosystem, government should ________.
A. forbid locals from taking firewood from the mountainsides
B. encourage local people to feed their animals just with straw
C. spend large amounts of money relocating the population
D. protect the environment without harming locals' interests
2.The forestry coverage in rural Beijing has increased greatly because ________.
A. pressures on land were reduced B. a large amount of coal is provided
C. no people live in that area D. locals take good care of the forest
3.According to the passage ________ play(s) a major role in ecosystem recovery.
A. local people B. nature itself

A. Nature reserves could be helpful to recover the damaged ecosystems.
B. Centrallyfunded nature reserves are beneficial to local economy.
C. Some nature reserves are created for the purpose of making money.
D. The first projects on nature reserves should be set up in quakehit areas.
