In college , Spring Break (春假) is usually associated with the beach, parties and sleepless nights,
bringing about relaxation, free time and friends. Students who wish to spend their break doing
something productive and rewarding, however, may choose to participate in the Altemative Break
Program. It places college students in communities both at home and abroad.
The Program allows students to take part in various projects dealing with issues such as
literacy (识字 ) , homelessness and the environment. It includes helping kids with their lessons,
raising money for families in need and collecting data for environmental research.
The hope is that, by getting themselves involved in different environments, students will have the
opportunity to learn about members of communities and broaden their view. In turn, they will
incorporate (融合) their experiences and lessons learned into their own communities. In a word ,
the Program aims to encourage students to be active citizens and engage themselves in making a
difference in society.
In the spring of 2006, about 36, 000 students in the USA participated in the Altemative Break
Program.
Samantha Giacobozzi, now director of the Program, has been on five alternative break trips herself,
including trips to New Orleans, India and Dominican Republic. "I was a student who went on alternative
break trips and had my life totally transformed by that experience , " she said. " Every year , we meet
many students who have attended the Program. You can see changes in their life that are connected
with their altemative break experiences. "
The Program began in 1991. Today , it has become increasingly popular with college students
in the United States.
