【答案解析】[参考范文]
Unfolded before us is a story simply written yet profoundly meaningful. A lecturer used a 20 dollar bill and taught us a lesson of life philosophy. After the bill was thrown on the ground and made dirty by footprint, it was still wanted by people and was still worth 20 dollars. This story obviously intends to convey to us this message: self worth is a quality everyone of us needs in our life.
To my best knowledge, we can easily identify the significance of self-worth from the following perspectives. To begin with, self worth is the basis on which we achieve success. You have to love yourself and acknowledge your self worth before you can be accepted and respected by others. Furthermore, self worth is the basis on which we can develop confidence to overcome hardships or failures. Without this quality, we would doubt about or even look down on ourselves and we would never be able to stand up again when facing frustrations or failures.
From what has been discussed above, we may safely draw the conclusion that with a strong self worth, we will have confidence in ourselves and even when confronted with setbacks, we will pull through. Without it, we are more likely to lose, be it in our work or social life. It is highly recommended that we make great efforts to cultivate and maintain self worth. [解析] 1．主题与类型：故事用20美元的钞票来比喻人的自我价值。这个题目容易直接定题为“自信的意义”，但从故事来看，更侧重人的自尊和自我价值。自信是对自己能力方面的肯定。而自我价值感更根本一些，是对自我认识最重要的肯定，是不依赖自身以外的人、事、物来证明的自身价值。文章是典型的意义分析型，论证的就是自我价值感(self worth)的意义。
2．结构与构思：题目考查方式为读后感，类型为意义分析型，因此文章可以分三个自然段。
第一段：首句为简述故事的功能句(Unfolded before us...meaningful)；接下来两三句话概括故事；最后写出引导主题的功能句(This story obviously...message:)，冒号后面跟上主题句，方式与素质意义分析型的类似(参考前面的范文)，可以表达为“自我价值(自尊)是每个人都应该具备的素质。”
第二段：段首句用上意义分析功能句“...we can easily identify the significance...following perspectives”。接下来展开分析意义，可以从自己、别人对自己的评价等角度来拓展分析。如果自己写的字数偏少，可以举例子。
第三段：首句使用意义分析型结论段主题句“...we may safely draw the conclusion that...”，重申自我价值的重要性。最后用素质意义分析型建议功能句“It is highly recommended...in our life”结尾，即表达培养和保持这种素质。
