本文为大家带来的是雅思流程图之水泥与混凝土的制作过程，流程图的写作相对而言较为简单一些，考生们要按照图中箭头指示方向进行写作，不过考生还是要细心并坚持练习，一定会有所进步。
雅思作文题目：
The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.(剑8 test3 task1)
范文：
The diagrams show the processes and the equipments used to make cement, and how these are used to produce concrete for building purpose.
The first step in the cement productions is to introduce limestone clay. These materials pass through a crusher that produces a powder. Then this powder goes into a mixer. After this, the product passes to a rotating heater which works with heat. Afterwards, the mixture goes into a grinder where the cement comes out. At the end of the process, the cement is packed in bags.
Referring to the concret production, the process begins with a combination of 15% cement, 10% water, 25% sand and 50% gravel. These four elements are introduced into a concret mixer.
As mentioned above, the concrete production takes fewer steps than the cement production, however, it is necessary to use more materials than the latter process in order to obtain the final product.
The last difference between both processes is that the concrete mixer does not work with heat.

四、论据积累：
雅思流程图的写作要根据流程图中的箭头指示方向而进行写作，描写的顺序千万不能弄错。
五、结构分析：
本图由两幅流程图构成。通过分析可知，考生除了要分别描述制作水泥和混凝土的过程之外，还要对这两种方法进行对比比较。
写作思路：
写作时可以分为四段：
第一段改写题目介绍主要内容;
第二段和第三段分别描写水泥和混凝土的制作过程;
第四段总结这两种制作方法的差异。
具体分析：
第一段：
改写题目，叙述核心内容：
The diagrams show the processes and the equipments used to make cement, and how these are used to produce concrete for building purpose.
processes 替换stages，make cement 替换cement-making;
不过，第一段描写的较为简单，考生可以先描写第一幅图的主要内容，在描写第二幅图的主要内容，分成两句话写。
比如：The first diagram describes the process and the equipment used to make cement, and the second shows how cement and other materials are mixed to manufacture concrete for building purposes.
第二段：
第二段描写水泥的制作过程：
The first step in the cement productions is to introduce limestone clay. These materials pass through a crusher that produces a powder. Then this powder goes into a mixer. After this, the product passes to a rotating heater which works with heat. Afterwards, the mixture goes into a grinder where the cement comes out. At the end of the process, the cement is packed in bags.
introduce vt. 介绍;引进;提出;采用。不过在第一幅图描述时不是太准确，从图中可知，石灰岩和黏土是通过两个不同的输送带被添加进入一个捣碎机，而变成粉末，再紧着是以下的步骤。;
conveyor 输送带;
pass through 穿过...，通过....;
crusher 压碎机;
grinder 研磨机;
第三段：
第三段描述的是混凝土的制作过程：
Referring to the concret production, the process begins with a combination of 15% cement, 10% water, 25% sand and 50% gravel. These four elements are introduced into a concret mixer.
concret 应改为concrete;
refer to 关于，参考，涉及，指的是;
begin with 以...开始;
gravel 碎石，砂砾;
最后一句话可以描述的更清楚一些，比如：The four elements are put into a concrete mixer where they are rotated so that concrete can be produced.
第二幅图中有箭头显示的是mixer要通过旋转的方式来加工混凝土，因此，在描述时最好写出来。
第四和五段：
两段指出两种方法的异同：
As mentioned above, the concrete production takes fewer steps than the cement production, however, it is necessary to use more materials than the latter process in order to obtain the final product.
The last difference between both processes is that the concrete mixer does not work with heat.
As mentioned above 如上所述;
final product 最终产品，成品;
work with 采用;
参考译文：
这些图显示了水泥的制作流程和所用到的设备，以及如何用这些来制造用于建造房屋的混凝土。
生产水泥的第一步是添入石灰石(和)黏土。这些材料穿过捣碎机，变成粉末。接着粉末进入搅拌器。 之后，产品经过加热的旋转加热器。接下来，混合物进入研磨机，水泥就出来了。在工序的最后水泥被装包。
在混凝土制造方面，其工序的第一步是要将15%的水泥，10%的水，25%的沙和50%的石子进行混合。这四种成分被放进混凝土搅拌器。
如上所述，混凝土生产需要的步骤比水泥生产要少;但前者需要使用更多的材料以获取最终产品。
两大制作流程的最后区别在于混凝土搅拌机不需要加热。
以上就是雅思流程图之水泥与混凝土的制作过程的详细内容，通向雅思写作高分之路并不容易，考生要有恒心，找对方法才会有事半功倍的效果。最后祝大家都能理想的雅思成绩，更多雅思备考经验我们将会陆续为大家更新，前程百利雅思考试频道不可错过!欢迎咨询我们的热线电话400-890-6000。
