Section Three Oral Work Part 1 Questions and Answers
Connie and Ann are having tea together. Connie: Guess who I met yesterday.
Ann: Thomas. Connie: Oh. Did somebody tell you? Ann: No.
Connie; I can't imagine how you guessed, then.
Ann: Well, you told me he was back from Canada, you know. Connie: Oh, did I? Yes, he got back three days ago.
Ann: And have you found out what he's been doing over there? Connie: He's told me all about it. Ann: Come on, then, you tell me.
Connie: Well, you know he wanted to try an open-air life, but he couldn't decide whether he should be a cowboy or a lumberjack. Ann: So what did he do?
Connie; First of all, he got a job as a cowboy, but he wasn't very good at it.
Ann: Oh, why not? Connie: Well, for one thing, he could never remember which horse was his.
Ann: That certainly sounds like Thomas. Once he forgot which girl he'd taken to a dance.
Connie: I know, I was the girl. Anyhow, he wasn't a very good rider, either. The horse could never understand where he wanted to go. Ann: Oh yes. That must have been awkward.
Connie: Yes, he often got completely lost.
Ann: So I suppose he began to wonder if he'd better be a lumberjack instead?
Connie: yes, that's right.
Ann: And that's what he did. Was he any more successful?
Connie: Well, not really. You see he kept forgetting how dangerous the work was.
Ann: So what happened? Connie: He cut down a large tree and didn't realise which way it would fall.
Ann: Oh dear. Was he badly hurt? Connie: Only a broken leg. But while he was in hospital, he made up his mind what he really wanted to do . Ann: Oh good. What is it?
Connie: He decided to come back to England and look after me, so we're getting married next month.
