Virtual①reality

SUSAN：Frank，you've been working at the forefront of developments in virtual reality for many years.Can you tell us what virtual reality is and how it works【1】？

【1】what引导宾语从句；作动词tell的宾语。

FRANK：Of course.The basic definition of VR lies in② the name itself，which means“reality that is not real”【2】．When you wear a VR headset equipped with③ sensors④ and a screen，you are surrounded by three-D images，sounds and other sensory information，which creates a super-realistic effect called “presence”. Though you know the sensory information surrounding you is not real，part of your brain believes it is－and acts accordingly⑤.

【2】which引导非限制性定语从句，修饰先行词 the name ；that引导定语从句，修饰先行词reality。

SUSAN：Thanks，Frank.Can you give some examples of the practical⑥ applications VR has?

FRANK：I'd love to.There are a host of⑦ educational applications. Academic⑧ VR enables students to interact⑨ with others in a three-D environment.There are endless possibilities for the subject matter that can be created in a VR system.Imagine studying the solar system⑪ or the human body in a fully immersive⑫ environment.By delivering⑬ the content in a meaningful way，this new approach to learning manages to engage⑭ students' interest and enhance⑮ learning efficiency⑯.The applications can be expanded to make it easier to visualize⑰ data such as engineering projects and a variety of other design developments.It's pretty exciting!

SUSAN：This sounds like it has a lot of constructive⑱ applications.What about its uses for

highly developed technical industries such as medicine?

FRANK：Surgeons are already using robotic technology with VR to perform complex surgery.What if I told you that doctors could create a virtual“twin”in order to practise delicate⑲ surgery before attempting it on the patient？This technology can be applied to train new surgeons；it also enables experts to test new

techniques safely before trying them on human subjects.Treatments of anxiety and drug addiction⑳ are other valuable and cost-effective applications of VR.

SUSAN：That is amazing！It sounds like VR will be a life-changing technology as well as a life-saving one.How will it affect the different aspects of our everyday lives，such as entertainment，shopping and travelling?

FRANK：The entertainment industry is one of the most enthusiastic advocates of VR.Current game systems come with headsets so that players can enter virtual environments and play against either real or virtual opponents㉑.It won't be long before virtual museums and interactive㉒ three-D exhibitions become common.【3】When shopping online，you can look forward to being able to have your own virtual reality clone㉓ try on clothes and to see products with 360-degree views.Also，

people who want to go on holiday will have the opportunity to take a virtual tour of several destinations before deciding where to go.In both of these cases，this technology will help people make more informed㉔ choices.

【3】before引导时间状语从句。

SUSAN：I can't wait！However，as with㉕ any technology，there must 【4】 be some barriers㉖ to the development of VR，I guess?

【4】must表肯定推测，意为“一定……”。

FRANK：It really boils down to㉗ three things—time，cost and technical limitations. We will need time to develop and fine-tune㉘ the hardware and software.The initial㉙ cost will discourage㉚ most people in the beginning but that should be fixed over time.The last issue is our own technical limitations.Just trying to figure out㉛ how to do what we want in terms of technology will prove challenging in some areas 【5】．

【5】what引导宾语从句，作动词do的宾语。

SUSAN：Considering㉜ there are so many challenges to deal with，are you still optimistic㉝
