___Stephen: Last summer I went through a training program and became a literacy volunteer. When I began to discover what other people's lives were like because they could not read, I realized the true importance of reading.
___Susan: I'm a girl from England and has studied French for years. I'm here in Fudan University studying Chinese. I like China as it is full of mysteries. So I hope the voluntary work will help me to get in touch with Chinese people and get to know about China．Although my study is busy, I can be free at night and at the weekends.
__Tim: Since I myself have overcome a lot of difficulties in my life, I understand young people's problems and I know how to listen patiently to others and offer some advice. I'm working now in the daytime so I can only spend two to three hours a day at night to help others.
Lisa: I burst into tears when I saw those children in a TV programme. What a sight. They are only bone and skin left. What's worse, every day the children are dying because of lack of food．I realized how lucky I am with enough food and a good chance to get education. The summer vacation is coming and I hope I can do something for them.

B．Tom is so addicted to on-line games that he cannot concentrate on his study like before.

How badly he needs someone's help.

C．Mane, a 44-year-old single mother of three, has to walk two miles to the nearest supermarket twice a week because she doesn't know which bus to take. What's worse, since she does not know words, she can not write out a shopping list. Also, she can only recognize items by sight, so if the product has a different label, she will not recognize it as the product she wants.

D．"Helping hand" organization will hold an event to help the starving children in Africa．The event starts in August and those taking part in will go without food for 30 hours. In this way, it is expected that money will be raised for the poor children.
