     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.
