1、雅思（写作）模拟试卷 199及答案与解析 1 The diagram below shows how The Australian Bureau of Meteorology collects UP-to-the-minute information on the weather in order to produce reliable forecasts. Write a report for a university lecturer describing the information shown below. 2 Using the information in the diagram
2、, write a description of how a refrigerator works. You may use your own knowledge and experience in addition to the diagram. 雅思（写作）模拟试卷 199答案与解析 1 【正确答案】 The diagram illustrates in four stages how the Australian Bureau of Meteorology gets its weather information to make weather forecasts. In the fir
3、st stage, it can be seen from the diagram that there is the “incoming information“. Raw data is collected from outer space, on land, or at sea, using satellite, radar, and drifting buoy respectively. Next, we can see from the diagram that this data is analyzed and forecasted by experts. At this stag
4、e, experts study satellite Photos, radar screens, and synoptic charts to determine weather conditions. Stage three of the process is when the information is prepared for broadcast. At this point, it is done through computer which sends the weather data to the media. In the last stage, it is obvious
5、from the diagram that the weather data is broadcast to the general public via TV, radio and telephone (recorded announcement). To sum up, the process diagram shows how weather data is collected, studied, prepared, and finally broadcast. 2 【正确答案】 The diagram shows in four stages how a refrigerator wo
6、rks. According to the diagram, in the first stage, high-pressure liquid flows in the capillary tube. Food within the refrigerator sends out vapor. In this stage, the high-pressure liquid is heated by the vapor to warm low-pressure gas. Next, the warm low-pressure gas flows ahead, arriving at the com
7、pressor. At this stage, it is compressed to hot high-pressure gas. Stage three of the process is when the hot high-pressure gas passes the condenser, where it is cooled to high-pressure liquid. Where is the heat then? It is transferred to atmosphere. Finally, the cool high-pressure liquid continues to flow forward and enters 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.
