20．People tend to become more personal and hide less of themselves when using e-mail．Researchers from Open University in Britain have found in a recent study that there are good reasons for this．
The team of researchers asked 83pairs of students，all strangers to each other，to solve a problem．They had to discuss this question：If only five people in the world could be saved from a world disaster，who should they be？The pairs of students had to talk over the problem either face to face or by computers．Dr．Johnson said，"They told their partners four times as much about themselves when they talked over the Internet as when they talked face to face．When the computers were fitted with （安装） cameras so that students could see each other，this limited the personal side of the conversation．"
Generally the information was not extremely personal．It was mainly about things such as where they went to school，or where they used to live．But some students discussed their love stories，and personal childhood experiences．
Dr．Johnson believes that e-mailing encourages people to focus on（专注于）themselves．And when they do this，they become more open，especially if there are no cameras．"If you cannot see the other person，it becomes easier to talk about yourself．This is because you are not thinking what the other person is thinking of you．So e-mailing has become the modern way of talking，"said Dr．Johnson．However，this style of talking is not entirely new．"In the 19th century people started to use the'telegraph'to communicate．Now the same kind of thing has happened and people ended up speaking more freely．"
Dr．Johnson thinks that e-mailers need to know about these effects of e-mailing，especially when they start work in a company．"If you don't know about it，you could find yourself saying more about yourself than you wanted to．"

分析 本文介绍了电子邮件为人们的日常交流提供了一个广阔而又隐秘的平台，由于人们彼此之间见不到对方，因而更容易敞开心扉，坦诚地交流．
解答 33．A；主旨大意题．本文是一篇研究报道，第一段是文章的中心段，根据本段第一句话"People tend to become more personal and hide less of themselves when using e-mail"（在使用电子邮件时，人们倾向于变得更个人化，更少地隐藏自己）再结合下文可判断文章的中心话题是人们在使用电子邮件时是如何开诚布公地交流的．故选A．
34．B；推理判断题．结合第二段最后两句"They told their partners four times as much about themselves when they talked over the Internet as when they talked face to face．When the computers were fitted with （安装） cameras so that students could see each other，this limited the personal side of the conversation．"（当他们在互联网上交谈的时候，他们对他们的伴侣说了四倍的时间，就像他们面对面交谈一样．当电脑安装了摄像头，让学生们可以看到对方时，这就限制了谈话的个人方面．）以及第四段前半部分中的内容可推断一些人敞开心扉的原因是他们彼此之间看不到对方．故选B．
35．D；推理判断题．最后一段提到在公司工作时要考虑到使用电子邮件的影响，假如不知道此事，就可能说出不该说的话，由此可推断D项正确．故选D．
