Earlier in the year, a UK government study found that in the UK we spend about half our waking hours using the media, often plugged into several things at once. And a recent study by Nielson found that on average, US teenagers send and receive over 3,000 texts per month—that's about six texts per waking hour. So, with technology continuing to develop at an alarming rate, how much time will you set aside for sleep in the future?

　　文章大意：两个小时不看电视，不上网不玩手机的话，你会有啥反应？看一下叫Unplugged的全球实验吧！

　　67．What's the purpose of the first paragraph?

　　A. To ask for information.

　　B. To entertain the readers.

　　C. To lead to the topic.

　　D. To present an idea.

　　答案：C　推理判断题。第一段用一个问题引出话题。

　　68．About Dr. Roman Gerodimos' experiment, we know that________.

　　A. volunteers felt uncomfortable in it

　　B. volunteers didn't want to eat anything

　　C. the experiment was still going on

　　D. volunteers were allowed to take their laptops

　　答案：A　细节理解题。由第三段第四句话“They're reporting withdrawal symptoms(症状), overeating, feeling nervous, isolated and disconnected”可知，实验的志愿者们都有不适的感觉。
