People without homes have always been present in America.In the past，they were called hobos，bums，or drifters.It was not until the early 1980s that these people received a new name，when activists named them the homeless.
The types of people who were homeless also changed in the 1980s.No longer were they primarily older men.They were younger，with an average age of 35.Their numbers consisted of women，children，adolescents and entire families.They were of many races and cultures.No longer were they only in the inner city.They lived in rural areas and in large and small cities.No longer were they invisible to the people with homes and jobs.The homeless of the 1980s lived in packing crates (装货箱) and doorways.They slept on sidewalks and in public parks.They begged money from passersby.
Counting the numbers of homeless people is difficult.However，in 1984 the Department of Housing and Urban Development estimated the homeless population at between 250,000 and 350,000.In 1990 the Census Bureau counted about 459,000 people in shelters，in cheap hotels，and on the streets.In 1995 the National Alliance to End Homelessness estimated that there were 750,000 homeless Americans.
The homeless of the 1980s also began to speak out for themselves.Some spoke to Congress and to government committees controlling funding for social programs.Street newspapers，such as Chicago’s Streetwise and Boston’s Spare Change，had stories，poems，and essays that expressed the homeless viewpoint.The visible and vocal presence of the homeless prompted help from volunteers and government agencies.But what is still needed is a solution to the plight of America’s homeless population.

Janice Fialka showed a new documentary (纪录片) about her cognitively (认知地) disabled son at schools and seminars across the country.Everyone seemed to enjoy it，but one comment from a teacher proved her family’s investment to Fialka was a success.
“In Baltimore an early childhood teacher came up and said，‘I have to apologize to the family of a 4year old with Down Syndrome (先天愚型)，’”Fialka said.“She said，‘I told them to be more realistic about their dreams for him.Now I have to tell them I’m sorry.’”
The story of Micah FialkaFeldman，a 22yearold Oakland University student，is meant to show parents，educators and the disabled anything is possible.
FialkaFeldman wrote in an essay titled “I wanted to go to college and my dream came true”．A lot of people didn’t think he could go to college，but because family and friends believed in him he learned how to take public transportation to campus and found teachers who helped him pick the best classes.
The title of the film Through the Same Door came from a day when FialkaFeldman，who was enrolled in a first grade special education program，told his parents he wanted to walk through the same door as the rest of the kids at his school.It led him to becoming the first student with cognitive disabilities in mainstream classrooms in Berkley.
Though he can’t read or write on his own，FialkaFeldman reached amazing heights with the help of voice recognition computer software，tutors，and the embrace (接受) of his community.
At Berkley High School，FialkaFeldman won the Social Studies Department Award for civic (公民的) involvement.In 2004 he received the Michigan “Yes，I Can” award for selfadvocacy (自强)．
He finished high school in 2003 with a certificate of attendance，took a 10day trip through Israel with friends last year，and enrolled at Oakland University through the Transitions Program，which is geared (使适合于) to help the disabled go from high school to college.
Fialka said he’s the happiest kid in the world.Everyone should be so happy.

Against the supposition that forest fires in Alaska，Canada and Siberia warm the climate，scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions.Usually large fires destroyed forests in these areas over the past decade.Scientists predict that with climate warming，fires may occur more frequently over the next several centuries as a result of a longer fire season.Sunlight taken in by the earth tends to cause warming，while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate.Earlier studies by other scientists had suggested that fires in northern regions sped up climate warming because greenhouse gases from burning trees and plants were released into the atmosphere and thus trapped heat.
Scientists found that right after the fire，large amounts of greenhouse gases entered the atmosphere and caused warming.Ozone (臭氧) levels increased，and ashes from the fire fell on faroff sea ice，darkening the surface and causing more radiation from the sun to be taken in.The following spring，however，the land within the area of the fire was brighter than before the fire，because fewer trees covered the ground.Snow on the ground mirrored more sunlight back into space，leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere，” scientists said.They tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire，and found a measurement closely related to the global air temperature.Typically，fire in northern regions occurs in the same area every 80 to 150 years.Scientists，however，found that when fire occurs more frequently，more radiation is lost from the earth and cooling results.Specifically，they determined when fire returns 20 years earlier than predicted,0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases，but 0.9 watts per square meter will be sent back into space.The net effect is cooling.Watts are used to measure the rate at which energy is gained or lost from the earth.
