On the other hand，I recently saw a scenario that demonstrated to me how deeply disconnected we as Americans have become. I had just wrapped up a presentation on mediation at a family therapy (治疗) center. As I was leaving，I noticed a mother and her teenage son who had just completed their session with their family therapist. After making their next appointment, they both took out their cellphones, made calls, and began loud conversations with whoever was on the other end. I walked out behind them to the parking lot to my car. They both jumped into their cars, and, as I saw them drive off，they were still talking on their cellphones. But，alas，not to each other.

　　1. What does the passage lead you to believe?

　　A. Americans are more socially connected today.

　　B. Americans are more socially isolated today.

　　C. Technology plays a bigger role in American society.

　　D. Americans don't make good use of technology.

　　答案：B　主旨大意题。文章作者引述了一项研究表明美国人变得越来越孤立，人与人之间的交流愈来愈少。

　　2. Which of the following has nothing to do with the isolation among Americans?

　　A. Age.

　　B. Education.

　　C. Skin color. D. Sex.

　　答案：D　细节理解题。由文章第二段最后两句可知，受教育程度、肤色以及年龄的差异对一个美国人是否变得孤立都有影响，而没有提到性别。
