【答案解析】[听力原文] 14-17
W: Edward Heath, you seem to have had two consuming passions in your life, music and politics, is it importan-t for a leader to have an escape like music or art?
M: I don't regard it as an escape, but I think it's very important that leaders should have a wide variety of interests. If you are just a politician and nothing but a politician, you gradually drive yourself into the ground.You become very inward looking and very narrow-minded. But if you've got other interests, you come back to problems with a fresh mind and you can serve your electors much better than you could otherwise.
W: Where did this interest of yours come from? Was yours a musical family?
M: It wasn't musical in the sense that Mozart's father was a professional musician and Bach had brothers and sons who were musicians. On the other hand, my mother and father both wanted to encourage me in music and my brother as well. He became a violinist while I was a pianist.
W: What about politics?Was yours a political family?
M: It wasn't at all. Ply father, I think, would have described himself as a Liberal. I became interested in politics at school, very largely through a debating society. I've always enjoyed debating and arguing with people.
W:It is one thing to be interested in politics; it is another to want a political career.
M:Well, I became seriously interested in politics towards the end of the war, not in a party sense but in a general sense: that we couldn't allow Europe to tear itself apart again. If we were going to survive then we ought to do something about it after the war.
