雅思小作文——流程图
出现频率：低
难易程度：高
流程图和普通图表的区别在于：
●流程图基本上不会出现数据，文字信息占主要地位
●流程图以描述为主，比较的概率比较少
●流程图需要把图中出现的信息都做描述，而普通图表则不需要将每一个数据都表
述
●流程图的时态比较单一，主要是用一般现在时
●流程图的分段比较灵活，只要不同阶段之间的差距很明显，就可以另起一段
●流程图可以不写总结段【如果写总结段，可以把步骤稍微总结一下】
流程图注意事项：
1)注意掌握段落连接或者不同阶段之间的说法（sequence expression）
表示首阶段的一些说法：
①The process starts from （名词or动名词）
②At the first/initial stage + 句子
③At the beginning of the cycle + 句子
④During the initial phase + 句子
transform和convert的区别
⑤The beginning of the whole cycle is marked by （名词or动名词）
⑥（名词or动名词）is the first step in （名词or动名词）
表示次阶段的一些说法：
①The second stage is（名词or动名词）
②The next step in the process is （名词or动名词）
表示最后阶段的一些说法：
①（名词or动名词）is the last step in the procedure
②The final phase of the procedure is about （名词or动名词）
③In the final phase + 句子
④Entering the final phase + 句子
⑤（名词or动名词）is the final stage
2)单词的转换主要体现在名词转换成动词。流程图经常会出现一些器具的名词，如
“grinder”“mixer”“heater”，考生需要改动成名词使用，如”ground”, “mixed”
和”heated”
例：The powders are delivered to the grinder, where they are ground into cement.
3)注意流程图读图的顺序，很多是以循环形式出现
4)除了连接词外，还可以使用分词结构和状语从句来表示顺序，如：下面几句话的
意思是一样的，
●Liquor butter is filtered, before being converted into solid butter.
●Once liquor butter is filtered, it is converted into solid butter.
●Liquor butter is filtered, until it is converted into solid matter.
5)常用被动语态
●误：Put these materials in the heater.
●正：These materials are put in the heater.
6)工序图的叙述流程图可以遵循下面的步骤：
步骤1：确定材料
步骤2：确定工具
步骤3：确定动词，然后将这些信息写成一句话。
7)De
例：《剑8》Test 3 Task 1
注意1：整理成文时，尽量多用分词结构。句1：Powder is place on the conveyor belt.
句2：Powder is ground by the grinder into cement.
可以合成一句：Powder is place on the conveyor belt, before being ground by the grinder.
注意2：使用once或者until引导的状语从句
例子：Ingredients are rotated in the concrete mixer, until they are turned into concrete.
注意3：加入适当的连词，写成篇章
The two diagrams show how cement and concrete are produced with different materials and facilities used.【改写题目】
At the first stage, limestone and clay are crushed by the crusher into powder. The powder is then delivered to the mixer, where it is mixed. The mixture is subsequently sent to the rotating heater, after which it is heated and rotated. In the next step, the rotated powder is placed on the conveyor belt, before being ground by the grinder into cement. This final product is packed in bags.
In the process of the concrete production, gravel accounts for 50% of materials, while cement, water and sand represent 15%,10% and 25% respectively. These materials are placed in the concrete mixer, which rotates clockwise（顺时针方向）until concrete is produced.
To summarise, cement production consists of 4stages,starting from crushing materials into powder and ending at bagging cement. In contrast, concrete production is simple, mixing four materials.
