A、Trainees. B、Undergraduates. C、Volunteers. D、Part-timers. B选项表明本题考查对话双方的身份。对话一开始就提到Here is the summer vacation again。之后又提到we ha

M: Here is the summer vacation again. It seems that there is no new place in our country for me to travel.
W: I have an idea to make good use of our vacations. We have benefited from the society but done nothing in return. Do you want to do some local voluntary work for the society this year?
M: Sounds interesting. What do you think we should do?
W: I’m not sure. Maybe we could offer help in the hospital for handicapped children. We could help feed the children and help look after them.
M: Excellent! But I’m not sure if we will be allowed to do that. I think all helpers there have to be specially trained. And we are not in the related major.
W: Yeah, maybe you are right. I still have the idea of doing something for children, haven’t you?
M: Well, maybe. And I think many old people also need help. What else did you have in mind for children?
W: My other idea was to do something for the small primary school down the street. That school is too poor to provide a playground for the pupils. Children cannot do without one. I’ve noticed that some land round the back of the school is not used. We could make it into a small playground. What do you think?
M: Mm, it’s a good idea, but you are a bit too ambitious. I don’t know anything about making playgrounds. And I also think that it might be too expensive to do what you suggest.
W: Yes, I guess you’re right. We cannot afford the big project unless someone sponsors us. It’s impossible for us to find such a person. So what do you have in mind for older people?
M: I think we should go round to the homes of older people and ask if there is something we can do in the house — you know, like a bit of simple decorating, washing the clothes, cleaning up the garden, even doing some shopping for them once a week.
W: Mm, this sounds meaningful and practical. I quite like the idea. It won’t cost us any money and I’m sure we are capable of dealing with the things you mentioned.
