Period 4　课时学案 单元语法讲练(Grammar and usage) FRANK：Of course④．The basic definition⑤ of VR lies in⑥ the name itself，which means “reality that is not real”[2]．When you wear a VR headset⑦ equipped with⑧ sensors⑨ and a screen[3]，you are surrounded by⑩ 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[4]—and acts accordingly． Period 4　课时学案 单元语法讲练(Grammar and usage) [2]which引导的非限制性定语从句。 [3]when引导的时间状语从句。equipped with sensors and a screen是过去分词短语作后置定语，equip与headset 之间是被动关系。 [4]这是一个主从复合句。句中包含一个though引导的让步状语从句，其中know后面有一个宾语从句 the sensory information surrounding you is not real，其中surrounding you是动词-ing形式短语作定语，修饰the sensory information。主句中believes后接一个宾语从句 it is。 Period 4　课时学案 单元语法讲练(Grammar and usage) SUSAN：Thanks，Frank．Can you give some examples of the practical⑪ applications VR has?

Period 4　课时学案 单元语法讲练(Grammar and usage) FRANK：Surgeons are already using robotic technology with VR to perform complex surgery．What if㉔ I told you that doctors could create a virtual “twin㉕” in order to practise delicate surgery before attempting it on the patient[6]? This technology can be applied to㉖ train new surgeons；it also enables experts to test new techniques safely before trying them on㉗ human subjects．Treatments of anxiety and drug addiction are other valuable and cost-effective applications of VR． Period 4　课时学案 单元语法讲练(Grammar and usage) [6]that doctors could create a virtual “twin”是宾语从句。in order to practise delicate surgery作目的状语；before attempting it on the patient作时间状语。 Period 4　课时学案 单元语法讲练(Grammar and usage) SUSAN：That is amazing! It sounds like VR will be a life-changing technology as well as㉘ a life-saving one．How will it affect the different aspects of our everyday lives，such as entertainment，shopping and travelling? Period 4　课时学案 单元语法讲练(Grammar and usage) 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 or㉙ virtual opponents[7]．It won't be long before virtual museums and interactive three-D exhibitions become common．[8]When shopping online，you can look forward to㉚ being able to have your own virtual reality clone㉛ try on clothes and to see products with 360-degree Period 4　课时学案 单元语法讲练(Grammar and usage) views．Also，people who want to go on holiday㉜ will have the opportunity to㉝ take a virtual tour㉞ of several destinations before deciding where to go[9]．In both of these cases㉟，this technology will help people make more informed choices㊱． Period 4　课时学案 单元语法讲练(Grammar and usage) [7]so that引导目的状语从句。句中含有两个并列的谓语动词enter和play。 [8]句型“It won't be long before... ”用不了多久就…… [9]who want to go on holiday是定语从句，修饰先行词people。before deciding where to go是时间状语；where to go是“特殊疑问词＋不定式”结构，作deciding的宾语。 Period 4　课时学案 单元语法讲练(Grammar and usage) SUSAN：I can't wait！㊲ However，as with㊳ any technology，there must be some barriers㊴ to the development of VR，I guess? FRANK：It really boils down to㊵ three things—time，cost and technical limitations．We will need time to develop and fine-tune㊶ the hardware and software．The initial㊷ cost will discourage most people in the beginning㊸ but that should be fixed over time㊹．The last issue is our own technical limitations．Just trying to figure out㊺ how to do what we want in terms of㊻ technology will prove challenging in some areas． [10] Period 4　课时学案 单元语法讲练(Grammar and usage) [10]Just trying to figure out... technology是动词-ing形式短语作主语。how to do what we want in terms of technology是宾语从句作figure out的宾语。此外what we want in terms of technology也是宾语从句，作do的宾语。 Period 4　课时学案 单元语法讲练(Grammar and usage) SUSAN：Considering there are so many challenges to deal with㊼，are you still optimistic㊽ about the future of VR? FRANK：Sure．When talking about VR，we should keep in mind㊾ its quick rate of evolution．The possibilities seem endless．For example，5G technology，with its potential to serve up㊿ more stable mobile connectivity at faster speed51，will make it possible for people to enjoy a more immersive VR experience wherever they are[11]．Indeed we are only limited by our imagination．What excites Period 4　课时学案 单元语法讲练(Grammar and usage) me the most is that young people today are digital citizens who are comfortable with technology． [12] They're well equipped to become part of a technological generation that will develop and use VR to do things we might think impossible today[13]． SUSAN：Thank you，Frank．It all sounds wonderful． Period 4　课时学案 单元语法讲练(Grammar and usage) [11]句中it作形式宾语，其真正的宾语是to enjoy a more immersive VR experience... 。wherever they are是让步状语从句。 [12]What excites me the most 是主语从句，在句子中作主语。that young people today are digital citizens who are comfortable with technology是表语从句，其中包含一个定语从句who are comfortable with technology，作digital citizens的定语。 [13]that will develop and use VR to do things we might think impossible today是定语从句，修饰先行词a technological generation。其中还包含一个定语从句we might think impossible today，修饰先行词things。 Period 4　课时学案 单元语法讲练(Grammar and usage) 虚拟现实 苏珊：弗兰克，你已经在虚拟现实技术开发的最前沿工作了很多年。你能告诉我们虚拟现实是什么，它是如何工作的吗？ 弗兰克：当然。虚拟现实的基本定义在于其名字本身，意思是“不真实的现实”。当你戴上装有传感器和显示屏的VR耳机时，你会被三维图像、声音和其他感官信息所包围，这创造了一种超级现实的效果，叫作“存在”。虽然你知道周围的感觉信息不是真实的，但你大脑的一部分相信它是这样的——而且会采取相应的行动。 Period 4　课时学案 单元语法讲练(Grammar and usage) 苏珊：谢谢你，弗兰克。你能给出一些实际应用VR的例子吗？ 弗兰克：我很乐意。(虚拟现实)有大量教育方面的应用。学术虚拟现实使学生能够在三维环境中与他人互动。在虚拟现实系统中可以创建的主题有无穷无尽的可能性。想象一下在一个完全沉浸式的环境中研究太阳系或人体。通过用一种富有意义的方式来呈现内容，这种新的学习方式能够吸引学生的兴趣，提高学习效率。可以扩展应用程序，使可视化数据更容易，如工程项目和各种其他设计开发。这很令人兴奋！ Period 4　课时学案 单元语法讲练(Grammar and usage) 苏珊：听起来它有很多建设性的应用程序。它对像医学这样的高科技行业的用途如何？ 弗兰克：外科医生已经用机器人虚拟现实技术来做复杂的手术。如果我告诉你，医生可以创造一个虚拟的“双胞胎”，以便在病人身上做手术之前进行精密的手术，你会怎么做？这项技术可以用于训练新的外科医生；它还使专家能够在人类受试者上做实验之前安全地测试新技术。治疗焦虑和毒瘾是虚拟现实的其他有价值和成本效益的应用。 Period 4　课时学案 单元语法讲练(Grammar and usage) 苏珊：太神奇了！这听起来像是虚拟现实将是一种改变生命的技术，也将是一个拯救生命的技术。它将如何影响我们日常生活的不同方面，比如娱乐、购物和旅行？ 弗兰克：娱乐业是虚拟现实中最热情的拥护者之一。当前的游戏系统配备了耳机，让玩家可以进入虚拟环境，并与真实的或虚拟的对手一起玩。不久之后，虚拟博物馆和互动三维展览会很常见。网上购物时，你可以期待能够拥有与自己一样的虚拟现实克隆体用来试衣服，并能360度地看到产品。此外，想去度假的人将有机会在决定去哪里之前进行几个目的地的虚拟旅行。在这两种情况下，这项技术将帮助人们做出更明智的选择。 Period 4　课时学案 单元语法讲练(Grammar and usage) 苏珊：我等不及了！然而，就像任何技术一样，我想，VR的发展一定会有一些障碍对吗？ 弗兰克：实际上就归结为三件事——时间、成本和技术局限。我们需要时间来开发和微调硬件和软件。最初的成本会阻碍大多数人开始，但这应该会随着时间的推移而得到解决。最后一个问题是我们自己的技术限制。只是想弄清楚如何在技术方面做我们想做的事情，在某些领域会很有挑战性。 Period 4　课时学案 单元语法讲练(Grammar and usage) 苏珊：考虑到有很多挑战要面对，你对VR的未来仍然乐观吗？ 弗兰克：当然。当谈论VR时，我们应该记住它快速的进化速度。可能性似乎无穷无尽。例如，5G技术有潜力以更快的速度提供更稳定的移动连接，使人们无论在哪里都能享受更身临其境的虚拟现实体验。事实上，我们只是受到了我们的想象力的限制。最让我兴奋的是，今天的年轻人是数字公民，他们对技术很满意。他们已经准备好成为科技一代的一部分，他们将开发并使用VR来做我们今天可能认为不可能的事情。 苏珊：谢谢你，弗兰克。这一切听起来都很棒。 Period 4　课时学案 单元语法讲练(Grammar and usage) $
