     Our local Community (社区) Youth Club is a very popular organization with young people in my town.

I have been a member for four years now and I've taken part in a lot of interesting projects. These include

fun activities such as holiday camps and discos. We have even made a video.

     But it isn't all just enjoyment. We have also started doing social work to help people in our neighbourhood.

We have organized activities for small children during the holidays. We have also formed a special support

group to help young people stop smoking.

     We are particularly proud of the most recent group we have created. It organizes regular visits to the local

home for the elderly. This idea came from a school visit to a home for the elderly. My class spent an afternoon

at the home and everyone found the visit very rewarding (有意义的). The old people at the home were excited

by our visit. They were very talkative (健谈的) and they told us their personal stories. During our visit, the

home was full of the sound of laughter. We sang songs and played games with the old people and had tea

together. But we realized that life wasn't always easy. Some of them were in poor health and were very

unhappy. They couldn't go outside and the visits by children brought some sunshine into their lives.

     Many young people like me have very little contact with elderly people. As a result, we have a lot of wrong

ideas about them. We have little or no idea of the kind of lives they lead in the homes. After this visit, my

friends and I decided we should do something to help improve the quality of their lives.

     Since the creation of our visiting group over twenty volunteers have joined us. Up to now, we have

organized three group evening parties and a concert. But I think the individual (单独的) visits are the most

important. Club members regularly visit old people and everyone finds the experience rich and rewarding.
