【正文】 essure liquid continues to flow forward and enters into the capillary tube. At this point, it is heated by the vapor from food within the refrigerator again and a new cycle begins. Thus, the process diagram illustrates the principle of the refrigerator.十一 As a class assignment you have been asked to write a description of how this plastic is pro duced and then broken down. Using the information in the diagram, write a description of the cycle. You may use your own knowledge and experience in addition to the diagram. The diagram shows in four stages how plastic is produced and then broken down. According to the diagram, in the first stage, are harvested and taken to a factory. Next, in the factory, glucose is extracted from cereal crops. Stage three of the process is when the glucose then passes into a bacterial fermentation chamber, where the process of fermentation produces a type of plastic called PHB polymer. This can be used to make plastic bottles to hold sham poos and detergents. When these plastic bottles are thrown away，they may be disposed in three ways. First, they may be recycled. Another way is that they may also be filled in land. In this way, the oxidation products from the landfill sites are released slowly into the atmosphere. Other discarded bottles are burnt or biodegraded and send out carbon dioxide into atmosphere. Finally, cereal crops require carbon dioxide in order to grow, and these crops are used in the manufacture of the new plastic. Thus, the process diagram illustrates the cycle of the plastic.十二 The diagram below shows how The Australian Bureau of Meteorology collects uptothe minute information on the weather in order to produce reliable forecasts. Write a report for a university lecturer describing the information shown below. The diagram shows in four stages how the Australian Bureau of Meteorology gets its weather information in order to make weather forecasts. According to the diagram, in the first stage there is the “ining information”. Raw data is collected from outer space, on land, or at sea, using satellite, radar, and drifting buoy respec tively. Next, this data is analyzed and forecasted by experts. At this stage experts study satel lite photos, radar screens, and synoptic charts to determine weather conditions. Stage three of the process is when the information is prepared for broadcast. This is done through puter which sends all necessary data to the fourth stage. At this point the weather data is broadcast ed to the general public via TV, radio and telephone (recorded announcement). Thus, the process diagram illustrates how weather data is collected, studied, prepared, and finally broadcast.
