　　Task：The process of Australian Bureau of Meteorology collecting up-to-the-minute information on the weather in order to produce reliable forecasts.

　　思路解析：

　　1. 需要看懂圖形之間的順序，并找到流程的起點(diǎn)和終點(diǎn)。如：Incoming Information→Analysis Forecasting→Preparing The broadcast→Broadcast)

　　2. 需要理解圖形之間的因果關(guān)系。如：衛(wèi)星收集信息為因，衛(wèi)星圖片能被繪制為果)

　　3. 原則上，所有圖片及其圖片信息都需要被描述，盡量不要忽略圖形。

　　4. 在文字上，由于是進(jìn)行客觀描述，需要采用大量的被動(dòng)句式和定語(yǔ)從句。

　　5. 為了突出順序性，需要采用大量的連接詞進(jìn)行輔助說(shuō)明，如At first, Secondly, then, next, after that, finally等。

　　The flowing chart illustrates the process which is used to collect up-to-the-minute information on the weather by the Australian Bureau of Meteorology.

　　4 sequential stages should be required for forecast broadcasting, including information collecting, analysis and forecasting, computer-based preparing and broadcasting to the public.

　　Firstly, there is an all-around monitoring system based on 3 types of incoming information receivers, namelysatellite in space, Radar on land and Drifting buoy in ocean, all of which ensure a high-level integrity of data sources, geographically.

　　In phase two, for the purpose of analysis and forecasting, the original data is converted into visible patterns. Specifically, visual satellite photos can be obtained, figures can also be presented in radar screen, and synoptic charts can be drawn by the cooperation of radars and drifting buoys.

　　The next stage involves computer, which serves to make the preparation for broadcasting by synthesizing and processing the graphic information mentioned above.

　　At last, weather-forecast results are delivered into the public through different media, from Television to Radio to recorded telephone announcement.
