V. 课本讨论题

1. Can you think of other ways that information can be exchanged?

_____________________________________________________________________

参考答案：Yes. Besides the language forms above, we still have some other ways to exchange ideas or information. For example, in ancient times, Chinese people relayed fire signals at night and smoke signals in the day from one Great Wall watchtower to another so that war messages could be rapidly sent over great distances. And nowadays, people use the language of flowers to communicate meaning (e.g., rose =love; tulip = formal announcement of love; forget-me-not = keeping me in your memory).

2. Do you think English is important? Why or why not?

____________________________________________________________________

参考答案：Yes. Although Chinese is the most spoken language, English is the most widely used around the world. It's useful to learn English if you want to travel, do business or study abroad.
