Unless action is taken immediately, there is a good chance that all the oceans of the world will be dead by the year 2010.How can this possibly happen??

We have already seen that people allow all sorts of waste products to flow into the sea. It is almost impossible to measure how much waste water and industrial waste end up in our oceans, but we can find out how much oil is poured into them legally and illegally. It is illegal to pour oil into the sea close to the shore, but when a ship is many miles out to sea there are no such rules. Scientists have different ideas as to the amount of oil put into the sea, but the lowest figure for oil poured in European waters alone is nearly 200 000 tons every year. Some people say the figure could be ten times as high.?

It is not only our coasts that suffer from oil pollution. Among other things, many shell fish(creatures which live in water),and have a hard shell—oysters and mussels, for example—now have high amounts of poisonous substances. Next time you have shell fish to eat, how can you be sure that they are free from oil pollution? You cannot see the effects and you cannot taste them, either. It is really quite a problem.?

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 __2__! 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.
