【正文】 ement value of these Well, it’s hard to say because they were part of a set. But they can be up to 10 dollars each as it is such a good setOk so that would be around 60 dollars altogetherYes that’s rightAnd is that all of the items Yes so what do I have to do now?Section 2 Wele to green vale agricultural park, as you know, we’ve only been open a week, so you’re amongst our first visitors. We have lots of fascinating indoor and outdoor exhibits on our huge plex, spreading hundreds of hectares. Our remit is to give educational opportunities to the wider public as well as to offer research sites for a wide variety of agriculturists and other scientists. Let’s start by seeing what there is to do. As you can see, here on our giant wall plan, we’re now situated in the reception block, here. As you walk out of the main door into the park, there is a path you can follow. If you follow this route, you will immediately e into the rare breeds section where we keep a wide variety of animals which I shall be telling you a little more about later. Next to this, moving east, is the large grazing area for the rare breeds. Then further east in the largest section of our park is the forest area, south of the grazing area and in fact just next to the reception block is our experimental crop area. In the middle of the park, this circular area is our lake, this 2 small rectangular shapes here are the fish farms where we rare fish for sale. To the east of those is the marsh area which attracts a great many migrant birds, in the southeastern corner, beyond the marsh is our market garden area growing vegetables and flowers. All these areas can be visited by the general public for almost all the year, although, please take note of the large signs at the entrance to each area which tell you when certain areas are being used for particular controlled experiments and are therefore temporarily out of bounds to the public. You can see for yourself what a huge area the park covers and a key question is always how can we move around. Well you have a choice of means. All environmentally friendly, cars are banned in the park, we have bicycles which you can hire behind the reception block, the healthy ones of you can go on foot. And finally there is our electric tram powered from solar cells. You find more information about this at the front entrance. A good place to start on your tour is the rare breeds section. We keep goats, sheep and hens and other kinds of poultry. We are also thinking of bringing cows and horses but we do not, as yet, have facilities for these bigger animals. The animals are fed in public twice a day and a short lecture given on their feeding habits and nutritional needs. These are very popular with the public but of course you mustn’t lose sight of the main purpose of having this section, not as such to preserve rare animals but to maintain the diversity of breeds to broaden the gene pool for agricultural development. Green vale changes with the seasons with different events happening at different times of the year. May will be perhaps our most spectacular month with the arrival of the Canadian geese and when our fruit trees will be in full blossom. But there are interesting events on all year round, for example, john havers, our expert fly fisherman, is currently giving displays on the lake. Each of the sections has its own seasonal calendar. Please consult the summary board at the main entrance. And the final section, as we return to the reception blocks is the orchard.Do take time to browse round our shop, there is a wide selection of books on wildlife, some of them were written by local authors, and the history of farming, including organic farming, something which the park will be diversifying into in the ing month. Section 3 Good morning everyone, in today’s seminar Grand Freeman, a biologist who specializes in identifying insects and who works for the Australian quarantine service, has e to talk to us about his current research work. Right, well over to you GrandGood morning everyone, I’m sure that you know that the quarantine service regulates all food brought into Australia. Well obviously they want to protect Australia from diseases that might e in with imported goods, but they also want to prevent insect pests from being introduced into the country, and that’s where I have a part to play. Anyway, my current research involves trying to find a particular type of bee, the Asian honey bee and finding out whether there are any of them around in various states of Australia. We discovered a few of them in Queensland once and eradicated them. Now we’re pretty keen to make sure that there aren’t any more getting in, particularly to new south wales and other states. What’s wrong with Asian honey bees, are they so different from Australian bees?Well in fact, they look almost the same but they are infested with mites, microscopic creatures which live on them, and which can seriously damage our own homegrown bees, or could even wipe them out. Well, what would happen if Australian bees died outWell, the honey from Australian bees is of excellent quality, much better than the stuff the Asian bees produce. In fact, Australia exports native queen bees to a large number of countries because of this. When the European honey bee was first discovered out in the bush, we found they made really unpleasant honey and they were also too big to pollinate many of our native flowers here in Australia. That must have had a devastating effect on the natural flora. Did you lose any species?No, we managed to get them under control before that happened. But if Asian bees got in, there could be other consequences. We could lose a lot of money because you might not be aware, but it’s estimated that native bees’ pollination of flowers in vegetable crops is worth billion dollars a year. So in a way, they’re the farmer’s friend. Oh, and another thing is if you’re stung
