劍橋雅思8Test3Task1寫作范文

1. 作對比會非常困難,因為兩張圖表的流程是完全不同的。

2. 所有需要用到的名詞已經給出,但是考生也可將這些名詞轉化為動詞(如 :crusher-crush, grinder-grind, mixer-mix)。

參考范文：

The diagram on the left illustrates the process by which cement is made whilst the diagram on the right shows us how concrete is made.

We can clearly see that the first stage in cement production is to put two substances – limestone and clay – through a crusher to create a powder. This powder then goes through a mixer and is then heated in a rotating heater. Once the powder has gone through the mixer and heater, it is ground and the cement is packed into bags.

The diagram on the right hand side tells us that concrete is a mixture of four ingredients in differing proportions. Cement makes up 15% of the mixture, water constitutes 10%, sand 25%, and gravel (i.e. small stones) 50%. These ingredients are mixed in a rotating concrete mixer to make concrete.

In summary, the production of cement and the production of concrete appear to be fairly simple processes.

左邊的圖描述的是水泥生產的流程,而右邊的圖則是混凝土生產的流程。

我們可以從圖中清晰地看見水泥生產的第一個步驟是將石灰石和粘土放入破碎機中磨 成粉末。接著這些粉末進入到攪拌機里進行混合,然后在回轉預熱器中進行預熱。粉末一旦 進入攪拌機和預熱器,將被磨碎,水泥就此生產完成,之后便可以裝入袋中。

從右邊的圖可以看出,混凝土是由四種原料按照不同的比例混合而成的,其中水泥占 15%,水占 10%,沙子占 25%,沙礫占(如小碎石)50%。這些原料在一個旋轉的混凝土攪拌 機中混合而成混凝土。

總的來說,水泥和混凝土的生產流程看上去是相當簡單的。
