Process diagrams show how something is done or made. They always show steps/stages.

1.Try to write 4 paragraphs - introduction, summary of main points, 2 detail paragraphs.

写四段—1 intro、1 总结、 2 细节段

2.Write the introduction by paraphrasing the question (rewrite it by changing some of the words).

intro主要就是改写题目（改一些题目中的词汇，所以积累同转很重要！！后续考虑更新）

3.For your summary, first say how many steps there are in the process. Then say where/how the process begins and ends (look at the first and last stages).

对于总结段，首先阐述图中有几步，然后写这个流程是如何开始和如何结束的。

4.In paragraphs 3 and 4, describe the process step by step. Include the first and last steps that you mentioned in the summary, but try to describe them in more detail or in a different way.

第三第四段，分步描述流程图中的内容。同时，内容包括：在总阶段中提到的开始和结束（但是更细节的描述或者换种描述的方面），以及中间的步骤。

5.You could describe the steps in one paragraph, but it looks more organised if you break the description into two paragraphs. Just start paragraph 4 somewhere in the middle of the process.

关于细节段的描述，可以占一段，也可以占两段，但是如果分为两段会让整个流程更清晰，那就用两段吧！！

6.Mention every stage in the process.

流程图中的每一个流程都要被描述，因为每一个过程都会有分值权重。

7.Use 'sequencing' language e.g. at the first / second / following / final stage of the process, next, after that, then, finally etc.

在这个过程中，要学会连接词的使用，比如，after that/which...

8.Times (e.g. past dates) are not usually shown, so use the present simple tense.

时态的使用：一般使用现在时。

9.It's usually a good idea to use the passive e.g. 'At the final stage, the product is delivered to shops' (because we don't need to know who delivered the product).

通常情况下，用被动是一个好的选择，因为在流程中（比如某个产品的加工过程），我们并不知道是谁在做这个事情。

Example

The diagram illustrates the process that is used to manufacture bricks for the building industry.

Summarize the information by selecting and reporting the main features and make comparisons where relevant.

1.     用after which进行连接

Clay is dug up by a digger, after which it is further sieved with/by a metal grid, and then the finer clay is

尽量用被动语态

2.     用and then衔接前后两步

And then the finer clay is transported on a roller.

3.     Before进行连接

they are moved into a drying oven to dry for 24 to 48 hours, before the mixture is cut by a wire clutter or is molded into intermediate bricks.

4.     用once, after, until引导从句进行衔接

Once dried, the raw bricks are transported into the kiln

5.     任何一个设备后面都可以跟一个where引导的定语从句

The raw bricks are transported into the kiln, where the bricks are heated up under moderate temperature (200 ℃-980 ℃).

The diagram illustrates the process that is used to manufacture bricks for the building industry.

Introduction:

改写1：The diagram shows procedures of producing bricks for construction.

改写2：The diagram shows how the bricks for construction purpose are produced.

In the first stage, clay is dug up by a digger, after which it is further sieved with/by a metal grid, and then the finer clay is transported on a roller.

In the following stage, sand and water are mixed with the clay. The mixture cut by a wire clutter or is molded into intermediate product, before they are moved into a drying oven to dry for 24 to 48 hours. Once dried, the raw bricks are transported into the kiln, where the bricks are heated up under moderate temperature (200 ℃-980 ℃) first, and then they are dried further at higher temperatures ranging from 870 ℃ to 1,300 ℃, after which they are transferred into the chamber for 48 to 72 hours.

In the last step, the finished products are packaged to be finally delivered by a truck to industries that use them.

Overall, the whole process of making bricks has eight steps that begins with the collection of the clay, and ends with the delivery of the finished products to the market.

分析：大部分流程图都可以分成三个阶段：原料采集阶段、原料处理阶段、成品打包运输阶段
