B: It is looking at something 20 feet(英尺) away for 20 seconds(秒) after every 20 minutes of work on the screen(屏幕).
A: Thank you, Rick. 5 I’ll follow the rule.
B: 6

1. 2. 3. 4. 5. 6.

1.E 解析:根据下一句"You don't look well."可知,这里应该是先打招呼询问对方近况,进而发现对方状态不佳,所以选E项比较合适。
2.B 解析:由答句"Yes, I have some important work to finish by 6:00 this afternoon."可知,空处是在询问是否因为工作长时间使用电脑等相关情况,B项符合语境。
3.C 解析:上文提到眼睛疲劳以及有重要工作要完成,这里应该是给出缓解眼睛疲劳的建议,C项符合逻辑。
4.F 解析:根据前一句"The 20-20-20 rule?"可知,这里是想知道这个规则具体是什么内容,所以选F。
5.D 解析:詹姆斯听了里克对规则的解释后,应该作出回应,D项表示了解到这个规则后他觉得挺好的,并且会按照规则去做,符合语境。
6.A 解析:因为前面詹姆斯说了"Thank you, Rick.",空处应该回应表示不客气之类的话,A项是常用的回应感谢的用语,所以选A。
