[originaltext]M: Hi Helen. What do you think of our class in children’s literat

M: Hi Helen. What do you think of our class in children’s literature?
W: It looks pretty good. I was surprised to see you in there. Are you also majoring in elementary education?
M: No, I’m not. But as a psychology major, I can use this to fulfill the requirements in developmental psychology.
W: Have you finished the first assignment yet?
M: Not yet. I just got the book today. How about you?
W: I started this afternoon. It’s great fun reading those wonderful children’s stories by Dr. Hughes.
M: Dr. Hughes? I didn’t remember seeing his name on the reading list.
W: His full name is Theodore Hughes Gazzel. That’s how he is listed on the bibliography. Dr. Hughes is his pen name.
M: I love reading those stories as a child. It’s been interesting now to read them from a different perspective. I guess they all give me a good idea on how children think.
W: Those stories are also great for class use.
M: How is that?
W: Well, take a typical Dr. Hughes’ book like The Cat in a Hat. It has a controlled vocabulary of about only 200 words.
M: So, that means the children get a lot of practice, using a small number of words over and over.
W: Exactly. In fact, The Cat in a Hat is written primarily to show how a controlled vocabulary reading could also be interesting and fun.
M: Well, it sounds like it is also going to be interesting and fun. I’ll get started on those readings tonight.
