Question

    From video games and museums to medical training, VR（virtual reality, 虚拟现实）has been changing our lives for the better. However, this wonderful new technology has a so-far unsolvable problem: It may make people feel sick from the VR experience. The feeling of sickness, caused by VR, is called cybersickness.

"With modern VR systems, the possibility of cybersickness after only 15 minutes' experience is from 40 to 70 percent," Thomas Stoffiregen, a researcher at the University of Minnesota, US said. This sickness is probably caused by sensory conflict （感觉冲突），explained Stoffregen. When you are wearing a VR headset, your body's motion sensors cannot match the information received by your eyes. For example, when we wear a VR headset and ride a virtual roller-coaster, we think we are going up and down, but our bodies stay still. It leads to the loss of balance. Sickness is from our bodies' natural reaction to the experience. Adding to this problem, women are more likely to feel sick from the VR experience than men.

According to a study by Bas Rokers, a scientist at the University of Wiscons in-Madison, US, one reason could be the headsets. To work properly, VR headsets must match up with your PD （pupil distance, 瞳距）. Since they are designed larger PD, not everyone gets the best experience. Rokers found the larger PD distance is, the greater discomfort will cause. Based on his studies, about 90 percent of women have a shorter PD than the headset is made and that's the reason why women are more likely to have cybersickness.

Cybersickness prevents the widespread use of VR technology. Once it becomes comfortable and easy to use, however, it could play a great role in our lives.

1.Which is Right about cybersickness?

A.It's a common problem with VR technology. B.It is caused by one's poor sense of direction.

C.It's more possible for young people to feel sick. D.It only happens to women and children.

2.The example of riding a virtual roller-coaster is used to _________.

A.tell what it is like to have cybersickness B.explain how cybersickness is caused

C.tell people how to avoid cybersickness D.show how cybersickness influences people

3.Why are women more likely to have cybersickness?

A.They have a poor sense of direction. B.VR headsets are only made for men.

C.VR headsets are too large for their PDs. D.They are easy to lose balance.

4.What does the writer think of the VR technology?

A.The VR technology has already played a great role in our lives.

B.There is still something to do before VR technology plays a great role.

C.The VR technology is comfortable and easy to use for everyone.

D.It's impossible for VR technology to be popular in the future.

【解析】

这是一篇说明文，文章主要讲述虚拟现实技术在发挥重要作用之前有问题需要解决，那就是网络病，并介绍了网络病产生的原因。

1.

推理判断题。根据第一段“this wonderful new technology has a so-far unsolvable problem: It may make people feel sick from the VR experience. The feeling of sickness, caused by VR, is called cybersickness”这个新技术有难以解决的问题就是网络病，可知A选项表述正确。根据第二段“is probably caused by sensory conflict ”可知B选项表述错误。根据第三段“women are more likely to have cybersickness”可知C选项表述错误。根据第二段“ women are more likely to feel sick from the VR experience than men”可知D选项表述错误。故选A。

2.

细节理解题。根据第二段“When you are wearing a VR headset, your body's motion sensors cannot match the information received by your eyes. For example, when we wear a VR headset and ride a virtual roller-coaster, we think we are going up and down, but our bodies stay still. It leads to the loss of balance. Sickness is from our bodies' natural reaction to the experience. ”可知举例在解释网络病是怎样引起的。故选B。

3.

细节理解题。根据第三段“To work properly, VR headsets must match up with your PD （pupil distance, 瞳距）. Since they are designed larger PD, not everyone gets the best experience. Rokers found the larger PD distance is, the greater discomfort will cause. Based on his studies, about 90 percent of women have a shorter PD than the headset is made and that's the reason why women are more likely to have cybersickness.”可知女性更有可能有电脑病是因为VR眼镜对她们的 瞳距来说太大。故选C。

4.

观点态度题。根据最后一段“Cybersickness prevents the widespread use of VR technology. Once it becomes comfortable and easy to use, however, it could play a great role in our lives.”网络病阻碍了VR技术的扩散，一旦它变得舒服和容易使用，它将在我们生活中发挥重要作用。可知作者觉得在VR技术发挥重要作用之前仍然有问题急需解决。故选B。
