讲课用的textbook: College Writing Skills with Readings, Ninth Edition (美国大学英语写作第九版) by John Langan (available on jd for less than RMB70)。
这是一本不需要老师就可以自学的教科书。才两杯星巴克咖啡的价格。（我一般不光顾中国的星巴克。）
没有教科书，你只是路过看热闹。（就像我路过中国的星巴克。）
You can get a free copy for the 7th edition:

but it is a very old version.
Part I: Essay Writing （如何写短文）
Chapter 3: The First and Second Steps in Essay Writing
This chapter will show you how to
· Start an essay with a point, or thesis
· Support that point, or thesis, with specific evidence
Step 2: Support the Thesis with Specific Evidence (用具体的论据支持论点)
The Importance of Specific Details
Specific details are valuable in two key ways. First, details excite the reader’s interest. Second, details serve to explain a writer’s points.
A box on p59 illustrates vague support vs. specific support.
The Importance of Adequate Details
It means providing enough specific supports, instead of using “repetition and generalities.”
