　　W: Yes, they said 12 at first, but changed to 10 this morning.

　　M: Good, we have 8 weeks to prepare, here are my suggestions. On the first day, a welcome party, then they can visit the schools in the district on the second and third days.

　　W: We’ve got to remember this group wants to look at how com¬puters are being used in the classroom.

　　M: Exactly, so I want to ask Mr. Goodman to give them a talk on this on the afternoon of the third day.

　　W: That will fit in very nicely.

　　M: And on the last day, they would do some sightseeing, we could take them on the tour of London but many of them may have been there already, and Scotland will be too far away.

　　W: Why not take them for a walk along the coast, it should be interesting.

　　M: Good idea! Cathy I’m sure they’ll like it.

　　W: There are many interesting stories about how a baby learns to say its first word. Now Mike, would you like to share your story with us?

　　M: OK, here’s my story, I was about 18 months old I think and I had just started to say my first word. Every time a truck went by, I would shout a word that sounded like a track, but to eve¬ryone else, it sounded nothing like it. My parents tried to cor¬rect me, but failed. Then, about three months later, we traveled to New York, as we were waiting for our plane at the air¬port. I looked out of a huge window, at that very moment I saw the largest truck in the world, I had to tell someone about this. I turned to my father who was standing next to about a thousand people waiting for the very flight and screamed “Track! Track!” My father tried hard to shut me up, but I was so excited, I kept screaming my special word. My poor mother decided she didn’t know this baby and then ran into the ladies-room where she hid until I finally stopped. Well, I learned how to say truck correctly, and soon I was talking like a normal child. Howev¬er, my parents will never forget the very first word I pro¬duced in my life.
