One possible version:

In the picture, four people are trying to fill a vat with water. Two men are carrying water while two others are pouring water into the vat. However, with so many loopholes at the bottom of the vat, they’ll never store any water, because no one tries to mend the holes.

It reminds me of the problems in our study. While studying, we always try to read more books and do more exercises. However, we seldom pay attention to the mistakes we’ve made, nor do we try to correct them. Therefore, “holes” are left. Day by day, there appear more and more “holes”, or rather the shortages. No matter how many books we’ve read, we have never mastered any knowledge because they have leaked out through the hole.

So we should pay attention to the mistakes we’ve made and the holes we have in our study. Only in this way can we learn much knowledge and fill up our mind with it.

题目分析：这是一篇看图作文，由图画中所反映得问题来联系实际谈谈学习中存在的问题。写作时不仅要将画面所包含的有效信息直接运用英语思维转换成英语语言文字进行描述，而且要就此联系实际而展开叙述。展开时需要围绕画面所反映的实质问题谈谈自己的思考和看法。写作时注意准确运用时态（因为是客观描述图画，又是谈谈自己的思考和看法，所以用现在范畴的时态），上下文意思连贯，符合逻辑关系。

【亮点说明】范文对图画的描述仅仅用了三句话：一个简单句，两个复合句。这充分显示了作者概括提炼图画所反映内容的能力。接着作者用“It reminds me of the problems in our study.”这个过渡句，就很自然地联系到我们的学习中存在的问题。将图画中的“缸的漏洞”与“学习中的错误”很紧密地挂起钩来，顺理成章。然后就对“学习中的漏洞”问题普遍存在的处理问题提出了自己的观点“小洞不补，则会吃大苦”，为后面的议论埋下了伏笔。最后一段为本文增添了亮点。范文中所用词汇非常丰富，且雅俗共赏。
