Context:
In a two-page essay entitled "What is E-commerce" (no question mark), the first paragraph concludes thus:
With the wide use of computer, the maturity and wide adoption of Internet, the permeation of credit cards, the establishment of secure transaction agreement and the support and promotion by governments, the development of E-Commerce is becoming prosperous, with people starting to use electronic means as the media of doing business.
Later (along with a complete rendering of the essay in Chinese), there are assorted sets of exercises, the last one being a collection of questions, the first question of that collection being "Why does E-Commerce become prosperous?"
The purported aim of the class is the teaching of commercial English, and in particular the English of E-Commerce. With the textbook being a collection of essays and assorted translation exercises, and some discussion, I'm focusing on the sound system of English and some exploration of terminology. Thus the "What is E-Commerce" class will be on the sound of itemised reasoning (falling intonation on the stress point of the last word of each item, and on the stress point of the last word of the conclusion) as compared to the sound of lists (rising intonation on the stress point of the last word of each listed point and a falling intonation on the stress point of the last word of the last listed item).
I might also have to have a go at this word "prosperous", although I wouldn't know what to teach other than "read more books to get a sense of usage!!!"
