How much can environment affect intelligence? In one study, striking increases in IQ occurred in 25 children who were moved from an orphanage(孤儿院) to more stimulating（使人兴奋的，使人振奋的） environments．The children, who were all considered mentally retarded and unadoptable, were moved to an institution where they received personal attention from adults．Later, these supposedly retarded children were adopted by parents who gave them love, a family ,and a stimulating home environment．The children gained an average of 29 IQ points．For one child, the increase was an amazing 58 points．A second group of initially less "retarded" children, who stayed in the orphanage, lost an average of 26 IQ points.
Other encouraging results can be found in early childhood education programs, which provide stimulating intellectual experiences for disadvantaged children．In one study, children from low-income families were given enriched environments from early infancy(婴儿期) through preschool．By age 2 their IQ scores were already higher than those in a control group．More important, they were still 5 points higher seven years later．High-quality enrichment programs such as Head Start can prevent children from falling behind in school.
A particularly striking environmental effect is the fact that 14 nations have shown average IQ gains of from 5 to 25 points during the last 30 years．These IQ boosts, averaging 15 points, occurred in far too short a time for genetics to explain them．It is more likely that the gains reflect environmental forces, such as improved education, nutrition, and living in a technologically complex society.

Have you ever thought, “I wish I could take a year off and just travel around the world”?
Well,three lucky American teenagers were able to do just that．The teens—two males and one female--got an all-expenses paid, yearlong hike to five continents.
This trip didn’t include any five-star hotels or shopping funs．Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment．They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with（遭遇） some of nature’s most dangerous animals and environments.
Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip．Earthwatch Institute sponsored this adventure．Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects．
The group went all around the world to get a close look at the most pressing environmental issues of our time．Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet．Time for change is running out．As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person's actions．They realized that each of them can make a difference.
