支招小作文（92） | 流程图 以甘蔗为原料制糖

* 流程图，选自《剑桥雅思真题集16》

Shown in the diagram is the procedure of making sugar from sugar canes. Overall, it is complex, taking multiple steps and using many pieces of equipment. 

* 流程图的总述就写过程是否复杂繁琐。还可以补充说用到的工具/器械的多少。

* 有些步骤可能合并成更少的句子。

First of all, when sugar canes ripen after 12 to 18-month growth, they are ready for the harvesting, which is done either by large machinery or by manual labor. The sugar canes are then put through a crushing machine to produce juice. At the next step, the juice goes through a funnel in which a limestone filter purifies the juice. The evaporator is the device in the next step, and it, using heat, makes syrup from the purified juice. With the syrup made, the centrifuge separates sugar crystals from the syrup. Once drawn/extracted from the syrup, the sugar crystals will be put into a cylinder to dry and cool, which is the final step of the whole process.

* 独立步骤避免用定语从句描述。定语从句只用于补充说明。

* 主体部分的这个段落中，老章提醒注意黄色高亮部分是状语的特殊形式，用于让流程之间连贯。

* 主体部分不一定要分成多个段落，仅写一个段落也是可以的，尤其是当流程之间的关系紧密的时候。

* 能不能没有结尾段落？可以。但是不能缺少的是对于图表的总述（在开头段落的第二句）。
