1．If you could be anybody in the world，who would it be？Your neighbour or a super star？A few people have experienced what it might be like to step into the skin of another person，thanks to an unusual virtual reality device．Rikke Wahl，an actress，model and artist，was one of the participants in a body swapping experiment at the Be Another lab，a project developed by a group of artists based in Barcelona．She swapped with her partner，an actor，using a machine called The Machine to Be Another and temporarily became a man．"As I looked down，I saw my whole body as a man，dressed in my partner's pants，"she said．"That's the picture I remember best．"
The set-up is relatively simple．Both users wear a virtual reality headset with a camera on the top．The video from each camera is sent to the other person，so what you see is the exact view of your partner．If she moves her arm，you see it．If you move your arm，she sees it．
To get used to seeing another person's body without actually having control of it，participants start by raising their arms and legs very slowly，so that the other can follow along．Eventually，this kind of slow synchronised（同步的）movement becomes comfortable，and participants really start to feel as though they are living in another person's body．
Using such technology promises to alter people's behaviour afterwards-potentially for the better．Studies have shown that virtual reality can be effective in fighting racism-the bias（偏见）that humans have against those who don't look or sound like them．Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test，which measures the strength of people's associations between，for instance，black people and adjectives such as good，bad，athletic or awkward．Then they asked them to control the body of a dark skinned digital character using virtual reality glasses，before taking the test again．This time，the participants'bias scores were lower．The idea is that once you've"put yourself in another's shoes"you're less likely to think ill of them，because your brain has internalised the feeling of being that person．
The creators of The Machine to Be Another hope to achieve a similar result．"At the end of body swapping，people feel like holding each other in their arms，"says Arthur Pointeau，a programmer with the project．"It's a really nice way to have this kind of experience．I would really，really recommend it to everyone．"

分析 文章介绍了一种Be another lab的体验，可以让人们互换角色，这样可以一定程度上消除人们的偏见，也可以促进人与人的相互理解．
解答 49．B．猜词题：根据第一段的最后的描写：She swapped with her partner，an actor，using a machine called The Machine to Be Another and temporarily became a man．"As I looked down，I saw my whole body as a man，dressed in my partner's pants，"she said．"That's the picture I remember best．"可知女演员和男演员互换角色，所以swapping的意思是"交换"，所以选B．
50．A．推理题：根据文章第三段的最后一句话：Eventually，this kind of slow synchronised（同步的）movement becomes comfortable，and participants really start to feel as though they are living in another person's body．可知从Be another lab的体验可以推断出我们的感觉和身体的经验有关，所以选A
51．D．细节题：根据文章第四段的句子：Studies have shown that virtual reality can be effective in fighting racism-the bias（偏见）that humans have against those who don't look or sound like them．可知在the Implicit Association test中，在参与者使用虚拟现实的眼镜控制一个深色皮肤的人物之前，他们对不像他们的人物更有偏见，选D
52．C．推理题：根据文章最后一段的句子："At the end of body swapping，people feel like holding each other in their arms，"says Arthur Pointeau，a programmer with the project可知虚拟现实帮助促进人们之间的理解，所以选C
点评 本篇文章多是细节、推理题，答题的已给选项也一般不会和短文相关词语完全相同，需要考生自己理解句子，延伸推理出题目答案．
