　　Shown in the diagram is using solar energy to make water pump work. The whole process goes through a number of steps and mainly uses three apparatuses.

　　* 流程图在开头处的总述就写“要经过几个步骤要用到几个设备”这样的套话。

　　主体部分阅读提示：

　　* 内容方面：当流程图中的信息不多时，可以通过补充说明工具/器械/设备的特征来增加篇幅。

　　* 文脉方面：使得文章连贯不仅仅可以通过“then”、“at this step”等词，还可以通过as引导的状语从句(如段落中的第3句)来承上启下。

　　* 词汇方面：动词是流程图的得分重点;如果还会一些特殊的名词的话就更好了。

　　* 语法句型方面：表语从句用来陈述步骤(如段落中的第1句)，定语从句或同位语用来补充说明工具/器械/设备的特征(如段落中第1句、第4句)，伴随状语(如段落中的第6句)用来补充说明步骤的具体情况。

　　The first step is that the solar panel, which is installed at the top of a post, collects solar energy. The panel consists of a grid of photovoltaic cells. As the energy is collected, it is converted to DC power. Then the DC power is transmitted to the bore pump – a mechanical device placed in the underground well and immersed in the water – and powers it. In addition, a small part of the well is above the ground level. At this step, the pump works, drawing the underground water up to an aboveground water tank through a zigzag pipe. The tank has a massive capacity and serves as a reservoir. Then, water is conveyed/transported to the village and its every household.

　　Overall, the entire process is not complex but rather simple.

　　* 流程图在结尾处的总述就写“复杂或者不复杂”这样的套话
