雅思小作文流程图怎么写

　　雅思小作文流程图怎么写？流程图写作的任务是写一篇报告，对图中的信息，特别是重要的阶段按顺序进行描述，写出明显的原因和结果等，但不要求考生发表意见。广州朗阁雅思资深老师认为：流程图与其他图表的描写方法有些不同。

　　广州朗阁雅思资深老师建流程图作文的写作要点总结如下：

　　根据常识，理解主题；起点开始，分清程序；理顺细节，抓住关键。

　　·描述流程中的各个重要阶段，必要时要扩充内容。

　　·说清楚所描述的阶段。

　　·通常情况下使用一般现在时的被动语态。

　　例题：Plastic litter is unsightly and appears never to rot away. Now chemists have produced a plastic that is made from sugar by bacteria, and when discarded, can be digested by other bacteria in the soil to form carbon dioxide.

　　You are asked to write a de锝擄絻锝掞綁锝愶綌ion of how this plastic is produced and then broken down.

　　Using the information in the diagram, write a de锝擄絻锝掞綁锝愶綌ion of the cycle. You may use your own knowledge and experience in addition to the diagram.

　　The diagram describes the cycle how plastic is produced and then broken down. Products made from the new plastic include bottles used to hold shampoos or detergents. When these are thrown away, they may be recycled, in other words, used again in the same form.

　　However, they may also be disposed of in landfill sites, in which case, unlike current plastics, they are digested by bacteria in the soil and break down. The oxidation products from the landfill sites and from other discarded bottles which have been burnt or havebiodegraded are released slowly into the atmosphere.

　　Cereal crops require carbon dioxide, which is one of these oxidation products, in order to grow, and these crops are used in the manufacture of the new plastic. The crops are harvested, taken to a factory, and glucose isextracted from them. The glucose then passes into bacterial fermentation chamber, where the process of fermentation produces a type of plastic called PHB polymer. This can be used to make plastic bottles for shampoos or detergents, and when these are discarded, the process begins again.

　　这里要注意的是，要对该过程作出准确而完整的描述。
