M: Helen, busy doing anything? W: Oh Kevin, I’m preparing a presentation for the city library. It’s about a girl named Tracy Woods. M: What’s special about her? W: It was an amazing story. She brought specially-trained dogs to special education schools and helped children to build confidence. She believes that dogs can help children in ways we can’t. Dogs don’t judge, and they don’t care who you are or what you look like. M: But putting dogs into a school? Aren’t they going to mess up the school? W: Don’t worry. All the dogs are assessed and trained properly. There are now 40 dogs working with children aged from 6 to 18. M: I hope the children love them. W: Of course they do. I’ve got some pictures. I’ll show them at my presentation tomorrow morning. 听下面一段较长对话，回答以下小题。
