雅思小作文题目分析：
本题考察饮用水的制作流程，图片信息量很小，内容简单，看懂不是问题，但有同学可能觉得内容简单到无从下手，怎样写够150字成为了不小的挑战。面对这种情况，有效的应对策略是仔细描述图片所有内容，不放过任何一个细节，必要时适当进行细节的补充。
本题有一个突破点是题目描述，不仅说到饮用水的制作过程，还提到滤水器的构成，所以完全可以分成两个主体段落分别描述构成和过程，这样以来字数就不成问题啦。

雅思小作文主体段范文：
The flow chart given provides information about the construction of awater filter and theprocess of producing clean drinking water by the filter.

Two major devices are involved in the waterfilter, a bucket with a wooden cover and a closed tank with a tap. There arethree layers in the bucket among which the charcoal is between the sand andgravel. At the bottom of the bucket is a long pipe linking through the threelayers to the closed tank.

There are two basic steps in the production ofdrinking water. The process starts from pouringimpure water into the bucket,which then is filtered through the sand, charcoal and gravel. Afterwards, the water flows through the pipe and finally into the storage tank where clean drinkingwater is stored. People could drink the water by simply turning on the tap atthe lower part of the tank.

Overall, it is clear that clean drinking watercould be produced through a two-step process with a simple water filter.
