Normally, when an expository writer chooses a subject to write about, he is choosing a subject to define. "Appetite", in an average dictionary, is defined as "natural desire for satisfying some want or need, esp. for food" which provides a very general explanation of the Word. But Lee in this passage would rather define it as "one of the major pleasures in life", "the keenness of living", "any condition of unsatisfied desire, any burning in theblood ... ", etc. As can be readily seen in "Appetite", to construct a definition over and above the dictionary one is .evidently not his major concern. By interpreting what "appetite" means to him, Lee actually is seeking to explain to his reader a relatively more abstract idea, a subject, a look at how to keep away from boredom in life. This explanation proves effective in that Lee has successfully utilized an approach revolving around definition which allows a complicated concept or even an abstraction to be looked at concretely instead of abstractly, thus helping to make it easier to comprehend.
Appetite is more often than not associated with the want for food, a feeling everyone has experienced and finds it easy to bring back to mind as to what it is like. In defining "appetite", however, Lee obviously intends to focus on desire in a broader sense. To make what he has ,in mind more comprehensible, the author frequently switches from one concept to the other so that the reader is given a chance to walk back and forth between the concrete and the abstract. Comparison is, therefore, one of a number of ways to approach definition. 《新编英语教程》第五、六册自初版以来将近九年。我们认为这两册教材的一个不足之处是:它们虽是同教程预备级和**至四册的继续,但内容远远不如后者完备。后者每册由学生用书、练习册和教师用书共三本组成一套,而第五、六册仅各有学生用书和练习参考答案共两本。有鉴于此,我们对第五、六册作了较大幅度的补充、修订,以期与预备级和**至四册取得一致,其修订版也各由学生用书、练习册和教师用书等三本组成一套。修订**如下:
一、学生用书。
1.少数课文作了删换。
2.课文I、Ⅱ的注释和课文I的篇章结构部分作了较大的补充。课文工的文体分析部分作了一定的调整。
3.新增段落写作部分(第五册)和文章写作部分(第六册)。
4.新增听说练习部分。针对不同题材的听力材料提问并要求讨论。

2.课文Ⅱ新增各种形式的练习。
