| Farmers, as we all know, have been having a hard time of it lately, and have turned to new ways of earning income from their land. This involves not only planting new kinds of crops, but some 1 ways of making money, the most unusual of which has got to be sheep racing. Yes, you heard me 6 ! A farmer now holds sheep races on a regular basis, and during the past year over 100, 000 people have 3 to watch the race. "I was passing the farm on my way to the sea for a holiday," one punter (赛马经纪人) told me, "and I thought I'd have a look. I didn't believe it was serious, to tell you the truth." According to a regular visitor, betting on sheep is more interesting than betting on horses. "At proper horse races everyone has already studied the form of the horse 4 , and there are clear favourites. 5 nobody has heard anything about these 6 ! Most people find it difficult to tell one from another in any case." I stayed to watch the races, and I must admit that I found it quite 7 . In a usual sheep race, half a dozen sheep race down hill over a course of about half a mile. Food is waiting for them at the other end of the 8 just to give them some encouragement, I ought to add! The sheep run surprisingly fast, 9 they have probably not eaten for a while. Anyway, the crowd around me were obviously enjoying their day out at the races, 10 by their happy faces and the sense of excitement. | ||||
