作文的第一段，要进行简单描绘图画内容，这是必须的，也是题目中强制要求的（a brief description of the picture）。描述的时候，只要把父子两的对话移植到第一段，然后把父亲手指垃圾桶的动作描绘一下就可以了，非常简单。

作文的第二段，进行主旨提炼并且论述。这幅图画很容易看出主题，那就是做大事之前，要先做小事（一屋不扫，何以扫天下）,而且题目中其实早就已经透露了主题了 （express your views on the importance of doing small things before undertaking something big.）因此，第二段通篇论述小事做起的重要性就可以了。属于我在课堂上讲过的作文三大分类之“积极主题，论述意义”

作文第三段，总结，启发。这一段再次强调小事做起的意义，我们不能低估他的威力。文章最后可以以名人名言作为结尾。

请看范文：

The picture shows us a dialogue between a father and a son. The son told his father, “Dad, I’m a bit worried about disposing of nuclear waste”. While his father told him, “If you can empty the dustbin here you can do anything”. It reveals the importance of doing small things well before undertaking something big. There is also an old Chinese saying to go with this that a person can’t sweep the world before he can sweep his own room.

I agree on the point that it is of great importance for a person to do small things well before undertaking something big. First of all, doing small things well entail the qualities that needed in doing great things such as patience and ability of controlling time. For example, when we sweep our room, we need to manage our time and energy reasonably. Accordingly, if we sweep a bigger room, for example, a classroom with our classmates, we should learn how to cooperate and allot assignments as well. And a big advantage is that we can draw useful lessons from the failure of performing well because they didn’t cost a lot.

In another word, though these things seem trivial, they reinforce our manipulative ability and thus our understanding to the world. Therefore, we should not ignore the small things.
