4．Professor Wiseman expects thousands of people to take part in an experiment in controlling dreams．
Participants will download a specially designed iphone app that turns their phone into a dream factory．Placed on the bed，the phone can monitor when a sleeper is not moving，which suggests the onsetof dreaming．It then plays a carefully crafted（精心制作的）"soundscape"designed to produce pleasant scenes such as walking in the woods，or lying on a beach．The idea is that this will influence dreaming，causing dreamers to form fantasyland inspired by the sounds they are hearing．At the end of the dream the app sounds a gentle alarm to wake the dreamer，who submits a brief description of the dream to a"dream catcher"database（数据库）．
Prof Wiseman，from the University of Hertfordshire，who is best known for his research on sleeps，said，"Getting a good night's sleep and having pleasant dreams promotes people's productivity，and is necessary for their mental and physical well being． Despite this we know very little about how to influence dreams．This experiment aims to change that．"
As many as 10，000 people are expected to take part in the study，declared at the Edinburgh International Science Festival．Prof Wiseman teamed up with app developers YUZA，which created the"Dream：ON"software．Participants will be encouraged to share their dreams via Facebook and Twitter．
A national survey conducted for the experiment found that 21% of people had trouble sleeping and 15%suffered from unpleasant dreams．Prof Wiseman said people feeling low dreamed far more than others，and often had negative dreams．"Perhaps improving their dreams might help them，"he added．
The"Dream：ON"app can be downloaded for free from iTunes or via the project site，http://dreamonapp．com．

分析 本文是一则广告，威斯曼教授希望成千上万的人参加一个控制梦想的实验．参与者下载一个应用程序，这个应用程序或许可以为参与者制造一个愉快的梦，而教授也可以通过实验了解梦是怎样被影响的．
解答 64．B． 细节理解题．根据文章"It then plays a carefully crafted"soundscape"designed to produce pleasant scenes"可知，梦软件可以制造出愉快的梦境．故选B．
65．D．细节理解题．根据文章"Despite this we know very little about how to influence dreams．This experiment aims to change that"可知，这个实验是为了改变很少人知道梦是怎么受影响这一现象的，即了解更多关于梦是怎样被影响．故选D．
66．C．细节理解题．根据文章"Participants will be encouraged to share their dreams via Facebook and Twitter．"可知，参与者应该在脸谱网和 Twitter上分享自己的梦．故选C．
67．C．词义猜测题．原文后句"It then plays a carefully crafted"soundscape"designed to produce pleasant scenes"写道，然后就制造出一个愉快的梦境，可见，这时，参与者只有睡着以后才会做梦．根据原句"Placed on the bed，the phone can monitor when a sleeper is not moving，which suggests the onset of dreaming"前半句写当睡觉的人不再移动时开始手机监控，可推测，这是梦的开始．"onset"是开始的意思．故选C．
点评 本文为广告布告类阅读文章．阅读这类文章时，也应该在整体把握文章结构的前提下，主要注意细节信息．细节题题干都是相应原文的变形（如同义改写、词性转换等），因此要找到答案一定要找到题干在原文中的出处，再把原文和选项相比较．做题时，根据所提问题用寻读、跳读的方法可达到事半功倍的效果．
