Question 12 is based on the conversation you have just heard.

W: Steve, can you tell me how long have you been a pub owner?

M: Well, four years I suppose. I’ve been involved with pubs off and on for ten years. I have sort of done hotel work. And I also ran a restaurant pub and now I have got what you have called an old fashioned pub. That is a public bar with all the social games going with it, which is what we have always wanted to have, you know.

W: It sounds like you have always worked in pubs but not always in this one.

M: No, no, I work in quite variety of pubs.

W: What makes a good pub? I mean you said, you know, it has got a good variety of things.

M: Well, I think having the right customers to start with, selling the right beer, keeping in good and most of all keeping a good attitude to yourself even though you probably feel very tired, but the idea is if you generate from you side, it got to effect the other side if you are getting the right customers in.

W: Yes, I must say that is one thing that always strike me about being a pub owner, I mean a lot of people think that is a nice job, you know. Everybody says “oh, I would love to retire and get a country pub” but it seems to me that is actually a very hard work.

(12). What does the man say about his involvement with pubs?

解析：原文中男士被问开酒吧有多久了，其回答有四年了，但断断续续地接触酒吧也有十年了，所以原文中没有提他的客户网，更不是中间四年中断了，故答案选C。
