M: We are lucky to have in the studio today, Molly Taylor. Molly is arranging an activity course for the summer holidays. Molly,this is the second year of the course,isn’t it?
W: Yes, that’s right. The summer course operated for the first time last year for a six-week period. This year we decided to keep to the same plan as last year.
M: But,as I understand,last year’s summer activity course was not a complete success,was it?
W: (19) Well,there were a few problems. The weather gave us some difficulties. There was such a lot of rain that we couldn’t go outside as often as we wanted to.
M: So,what activities can the children look forward to this year?
W: Well,once again there will be art and music experts coming in who will lead creative classes for the kids. (20) We are also introducing some fun projects—things that the kids can prepare together and show their parents what they have been doing.
M: It sounds fun. So,can children come on the course for the whole summer?
W: Sure. (21) But I don’t expect many kids will come for the whole summer,as I’m sure they will all go away with their parents for a week or two.
M: So,if a child or a child’s parent is listening, and is interested in coming to your summer activity course, what should they do?
W: (22) They should go to my website,and print out an application form. Send it in with a deposit as soon as possible, because the places are going fast.
M: Thank you very much for coming to speak to us, Molly. I hope the summer course is a success!
