     In 1970, tragedy struck the Gerstman family when Harvey and Carol Gerstman's daughter, Lisa

Beth, was killed in a summer camp bus accident. Because camp had been such a joy in Lisa Beth's life,

the Gerstmans wanted to start a foundation in her name. They wanted to bring that same summer camp

joy Lisa Beth felt to other children. When Lisa Beth's brother, Dan, heard the Cross Island YMCA

(CIYMCA) was looking for funds to help send physically disabled children to summer camp, he knew it

was the perfect way to keep Lisa Beth's memory alive.

     Dan soon learned that many disabled children spent the summer indoors while their ablebodied peers

enjoyed camp. The added costs of onetoone care and specialized busing for the disabled children

prevented them from being able to join in summer camp. The Gerstman family responded to this need

by setting up the Lisa Beth Gerstman Foundation in 2003. Its mission (使命) is to provide children with

physical disabilities the opportunity to attend camps in an integrated (综合的) setting.

     During its first summer, the foundation teamed up with CIYMCA and funded 20 physically disabled

kids with varying degrees of disabilities. The children were given the opportunity to experience the joys

of summer camp, build lasting friendships and develop their selfconfidence.

     Over the last five years, the Lisa Beth Gerstman Foundation has been partnering with camps that are

willing to launch (发起) integrated programs that include wheelchair accessible transportation, onetoone

swimming instruction, adaptive physical education equipment and training, all in a caring environment

where the children join in all regular camp activities.Last summer, the foundation partnered with six

camps, which allowed a total of 150 physically disabled children to experience summer camp.

1. What stopped disabled kids from joining in summer camp according to the passage?

A. Some extra costs for it.

B. Lack of enough time

C. No permission from parents.

D. Lack of selfconfidence.

2. What's the purpose of setting up the Lisa Beth Gerstman Foundation?

A. To develop children's confidence.

B. To raise money for disabled children.

C. To organize summer camp for different people.

D. To make it possible for disabled children to attend camps.

3. According to the passage, the Lisa Beth Gerstman Foundation ________.

A. is in the charge of CIYMCA

C. has gained support from camps

D. funded 150 disabled kids during its first summer
