Key structures in Text A:

1. Many experts think Vietnam is going too far by requiring that all mobile phones be expensive

digital models, when it is desperate for any phones, period. (Para.3)

The word “period” can be used at the end of a statement to show that you believe you have said all there is to say on a subject and you are not going to discuss it any more. For example: There will be no more shouting, period! 别再喊叫了，到此为止！

We are all against the proposal, period. 我们都反对这个建议，我说完了。

2. Wireless demand and usage have also exploded across the entire width and breadth of Latin

America. (Para.8)

The phrase “the width and breadth of” means “the entire extent of something”. Another phrase that is just as common is “the length and breadth of”.

The heroes traveled the length and breadth of the land, righting wrongs and helping people in need.

英雄闯遍天下，铲除不平，求助危难。

I have told you the length and breadth of what happened. 我也告诉你发生的一切。

3. That’s partly because Latin American customers talk two to four times as long on the phone as

people in North America. (Para.8)

Note the structure “two to four times as long as” in the sentence. We can use this structure to indicate the size or extent of something by comparing it to something else. For example: Water is eight hundred times as dense as air. 水的密度是空气的800倍。
