Shown in the diagram is the procedure of recycling plastic bottles. Overall, the process is moderately complex, consisting of a number of steps. 第 一句划线部分是一个倒装形式，当成套话记住。提醒注意：动词的单复数由后面的内容决定。第二句话陈述图的宏观情况。通常说来，就是说一下这个流程的复杂程度。
写主体段之前，老章的重要提示是：不要傻乎乎的每个步骤单独写，关系紧密(或者特别简单的)的步骤可以合并一起写。第 一句是图中三个步骤合并写： First, used plastic bottles are collected in recycle bins, and then transported to a recycling center – where those bottles are sorted. 第二句就是图中步骤三和四合并写：When being sorted, some of them are tossed, and the rest are kept and compressed into blocks. The next step is crushing the blocks into small pieces, and those pieces fall into a tank/basin in which they are washed. At the following step, an apparatus produces plastic pellets from those washed pieces. Then, with heat applied on them, those pellets are melted, and the molten substance is molded and becomes the raw material – fresh and neat plastic. 多样的句子主语或者句子开头是语法得分的重点。同时注意各种状语、定语、同位语，也是语法得分必备点。当然，黄色高亮的部是值得注意和记忆的名词、动词。
接下来可以分段(分段的原则是关系的亲疏，肯定不要在流程的关系紧密处分段，而是到了一个大的节点处分段)。The new plastic is then either made directly into end products – new bottles and containers, or used for making clothing, pens and recyclable bags. And when those products are no longer needed, some of them go to the recycle bin, and the recycling process starts again.
In light of all the steps, the cycle is not too complex. 开头段有了对于图的总述，结尾段有话就写，没话就不勉强写。但是老章还是写出来予以参考和提示。
