互聯(lián)網(wǎng)時代，Avatar成為網(wǎng)絡(luò)虛擬角色——網(wǎng)絡(luò)用戶在以圖像為主的虛擬世界中的虛擬形象——的代名詞。這類虛擬角色通常為卡通形象，他/她可以出現(xiàn)在論壇上，可以出現(xiàn)在聊天室中，也可以出現(xiàn)在游戲里。用戶可以根據(jù)自己的喜好，更換虛擬角色的造型，如發(fā)型、服飾、表情、場景等。在與其他虛擬角色交往的過程中，還可以使用各種虛擬商品，如鮮花、禮品等。而這些發(fā)型、服飾和禮品，都是需要付費(fèi)購買的。
最早推廣Avatar并將其商業(yè)化的是韓國的知名聊天網(wǎng)站SayClub，隨后這一模式很快為韓國市場所接受。隨后，以Hangame、NetMarble和Pmang為代表的韓國主流網(wǎng)站為互聯(lián)網(wǎng)開創(chuàng)了一種新的商業(yè)模式，我們姑且稱之為“Avatar模式”。
習(xí)慣表達(dá)中常用的虛擬語氣。
① 提出請或邀請。eg： Would you like to have a talk with us this evening?
今天晚上來跟我們聊天好嗎？
Could I use your bike now?
我可以用一下你的單車嗎？
② 陳述自己的觀點(diǎn)或看法。eg： I should glad to meet you.
見到你我會很高興。
I would try my best to help you.
我會盡力幫助你。
③提出勸告或建議。
eg： You'd better ask your father first.
你最好先問一問你的父親。 You should make a full investigation of it first.
你應(yīng)該先全面調(diào)查一番。
④ 提出問題。eg： Do you think he could get here on time
你認(rèn)為他能按時來嗎？
Do you expect he would tell us the truth?
你期望他會告訴我們真相嗎？
⑤表示對過去情況的責(zé)備時，常用虛擬語氣。其虛擬語氣的結(jié)構(gòu)為：情態(tài)動詞 have done。 eg： You should have got here earlier. 你早該到這里了。
You should have returned it to him. 你早該把它還給他了。贊同0|
虛擬語氣(Subjunctive Mood)這一語法項目是各類英語考試中心測試的重點(diǎn)之一。虛擬語氣是一種特殊的動詞形式，用來表示說話人所說的話并不是事實(shí)，而是一種假設(shè)、愿望、懷疑或推測。
⒈ 用if條件從句表示的虛擬條件，是虛擬條件最普通的方式。
① 虛擬現(xiàn)在時表示與現(xiàn)在事實(shí)相反的假設(shè)，其if 從句的謂語形式用動詞的過去式(be 一般用were)，主句用would/ should/ could/ might 動詞原形，例如：If I were in your position I would marry her.
② 虛擬過去時是表示與過去事實(shí)相反的假設(shè)，if 從句的謂語形式用過去完成時即had＋過去分詞，主句用would / should / could / might have 過去分詞，例如：If it had not rained hard yesterday we could have played tennis.
③ 大多數(shù)的虛擬條件句屬于上面三種情況的一種，但并不排除存在條件和后果中，一個和現(xiàn)在情況相反，另一個和過去情況相反，例如：If you had followed what the doctor said, you would not have been painful 。
④ 但是，如果后果用了虛擬語氣，而條件卻用陳述語氣，這種用法是錯的。
⒉ 除了表示虛假條件外，if從句還可以表示對將來的推測，由于是將來還沒有發(fā)生的，所以談不上是真實(shí)的還是虛假的，只能說這個事情發(fā)生的可能性有多大。一般情況下，可以用陳述語氣的if從句來表示對一個未來事實(shí)的推測，這個事實(shí)是完全可能發(fā)生的。If從句的謂語形式用一般過去式或用were to / should 動詞原形，主句用would / should /could/ might 動詞原形，例如：Jean doesn't want to work right away because she thinks that if she were to get a job she probably wouldn't be able to see her friends very often.（年題）
⒊ 有時可以把含有助動詞、情態(tài)動詞、be或have的虛擬條件句中的連詞if 省去，而將had , should, were 等詞提到主語之前，即用倒裝結(jié)構(gòu),這時候，如果出現(xiàn)not等否定詞，否定詞需放在主語后面。這種結(jié)構(gòu)在口語中很少使用，但頻頻出現(xiàn)在各類考試中出現(xiàn)，例如：If it had not rained hard yesterday we could have played tennis.→Had it not rained hard yesterday, we could have played tennis.
⒋ 大多數(shù)的虛擬條件通過上面所講的兩種方法表達(dá)，但在個別句子中也可以通過介詞without和介詞短語but for表達(dá)，副詞otherwise等表達(dá)出來。例如：We didn't know his telephone number; otherwise we would have telephoned him.（年題）值得注意的是，包含but for的句子，謂語動詞必定要用虛擬形式，但包含without等短語的句子，謂語動詞未必一定要用虛擬語氣。
⒌ 有時虛擬條件不是明確地表達(dá)出來，而在蘊(yùn)含在用but引導(dǎo)的從句里，于是便出現(xiàn)了有謂語動詞是虛擬語氣的主句加上謂語動詞是陳述語氣的but從句構(gòu)成的并列復(fù)合句，例如I would have hung you but the telephone was out of ，如果主句沒有用虛擬語氣，或者從句用了虛擬語氣，都是錯的。
Ⅱ用在賓語從句中的虛擬語氣
⒈ 在表示愿望的動詞wish后的賓語從句中，需用虛擬語氣。（wish后的that 常省略），根據(jù)主句時態(tài)，從句謂語時態(tài)相應(yīng)退后一位，例如：How she wished his family could go with him.
⒉ 在具有愿望、請、建議、命令等主觀意愿的動詞(desire, demand, advice, insist, require, suggest, propose, order, rmend, decide …) 后的賓語從句中需用虛擬語氣。謂語動詞用(should) 動詞原形。值得注意的是，如果賓語從句的動詞是否定的，否定詞not的位置應(yīng)在動詞之前，而不是動詞之后。例如：The head nurse insisted that the patient not be ，如suggest表達(dá)“暗示”，insist表示“堅持某種說法”時，后面的從句不用虛擬語氣，例如：Her pale face suggests that she is insisted that he did not kill the boy.
除此之外，上述動詞也要用虛擬式
① 在It is上述動詞的過去分詞，其后所跟的主語從句中，如It is suggested that pupils wear school uniforms.
② 在上述動詞相應(yīng)的名詞形式作主語連系動詞，其后的表語從句中，例如His suggestion was that classed be rescheduled.
③ 在對上述動詞相應(yīng)的名詞進(jìn)行解釋的同位語從句中，如：The workers raised the demand that their pay be increased to cope with the inflation.
⒊ would （had）rather , would oner也用來表達(dá)主觀愿望，它們之后的賓語從句中需用虛擬語氣。謂語動詞用過去式表示現(xiàn)在或?qū)?，用過去完成式表示與過去事實(shí)相反，例如：I would rather he went right now.
Ⅲ其他形式的虛擬語氣
⒈ it is necessary等形容詞后，that主語從句中虛擬形式使用，這類形容詞包括necessary, important, essential, imperative, urgent, preferable, vital, advisable等，例如It is necessary that you listen to the teacher is essential that you be able to pronounce every single word correctly.
⒉ 在It's (high/about) time 之后的定語從句中需用虛擬語氣。謂語動詞用過去式，例如It is high time that you went to school
⒊ 虛擬語氣在as if / as though 引導(dǎo)的方式狀語從句中的應(yīng)用（謂語動詞形式與wish后的賓語從句基本相同）表示與現(xiàn)在事實(shí)相反或?qū)ΜF(xiàn)在情況有懷疑，謂語動詞用過去式。例如：He felt as if he alone were responsible for what had happened. 表示過去想象中的動作或情況，謂語動詞用過去完成式。
⒋ 在lest 引導(dǎo)的狀語從句中，謂語動詞多用虛擬語氣，(should ) 動詞原形。例如： The mad man was put in the ftpadded cell lest he injure himself.
⒌ 在if only 引起的感嘆句中需用虛擬語氣。謂語動詞用過去式或過去完成式。例如： Look at the terrible situation I am in! if only I had followed your advice.
i: 最基本的虛擬語氣句型:
1. 虛擬現(xiàn)在時表示與現(xiàn)在事實(shí)相反的假設(shè)，其if 從句的謂語形式用動詞的過
去式(be 一般用were)，主句用would/ should/ could/ might 動詞原形。
if places were a like, there would be little need for geographers.
如果各個地方都一樣，就不需要地理學(xué)家了。
2. 虛擬過去時是表示與過去事實(shí)相反的假設(shè)，if 從句的謂語形式用過去完成時
即had＋過去分詞，主句用would / should / could / might have 過去分詞。
if he had known your address yesterday, he would have telephoned you.
3. 虛擬將來時是表示對將來實(shí)現(xiàn)的可能性很小的或不確定的假設(shè)。if從句的謂
語形式用一般過去式或用were to / should 動詞原形，主句用would / should
/could/ might 動詞原形。
if he were to leave today, he would get there by friday
4. 省略if 采用倒裝語序的條件句。
有時可以把含有助動詞、情態(tài)動詞、be或have的虛擬條件句中的連詞if 省去，而將had , should, were 等 詞
提到主語之前，即用倒裝結(jié)構(gòu)。
had he worked harder, he would have got through the exams.
were he to leave today, he would get there by friday.
were i in your place, i wouldn’t do that
5. 有時虛擬條件句并沒來if 從句表示出來，而是用介詞短語(otherwise, or, without, but for)、上下文或其它方 式來表示。
we didn't know his telephone number; otherwise we would have telephoned him.
without you help, i wouldn’t have achieved much.
but for your help, i would not have succeeded.
R：虛擬現(xiàn)實(shí)irtual Reality的英語縮寫。
虛擬現(xiàn)實(shí)技術(shù)是一種可以創(chuàng)建和體驗(yàn)虛擬世界的計算機(jī)仿真系統(tǒng)它利用計算機(jī)生成一種模擬環(huán)境是一種多源信息融合的交互式的三維動態(tài)視景和實(shí)體行為的系統(tǒng)仿真使用戶沉浸到該環(huán)境中。
AR：是增強(qiáng)現(xiàn)實(shí)Augmented Reality的英文縮寫。
增強(qiáng)現(xiàn)實(shí)是一種實(shí)時地計算攝影機(jī)影像的位置及角度并加上相應(yīng)圖像的技術(shù)，這種技術(shù)的目標(biāo)是在屏幕上把虛擬世界套在現(xiàn)實(shí)世界并進(jìn)行互動。這種技術(shù)最早于年提出。隨著隨身電子產(chǎn)品運(yùn)算能力的提升，增強(qiáng)現(xiàn)實(shí)的用途越來越廣。
MR：是混合現(xiàn)實(shí)Mixed Reality的英文縮寫。
混合現(xiàn)實(shí)技術(shù)是虛擬現(xiàn)實(shí)技術(shù)的進(jìn)一步發(fā)展，該技術(shù)通過在虛擬環(huán)境中引入現(xiàn)實(shí)場景信息，在虛擬世界、現(xiàn)實(shí)世界和用戶之間搭起一個交互反饋的信息回路，以增強(qiáng)用戶體驗(yàn)的真實(shí)感。
vr ( virtual reality )，虛擬現(xiàn)實(shí)
沉浸式地進(jìn)入虛擬世界消費(fèi)內(nèi)容，給用戶身臨其境的感覺。
這些內(nèi)容可以是電影、比賽、風(fēng)景、新聞等等，一些內(nèi)容還能進(jìn)行交互，例如vr游戲可以追蹤你的移動、步態(tài)、眼球、下蹲等等。
ar（augmented reality），增強(qiáng)現(xiàn)實(shí)
如果說vr給到消費(fèi)者的是一個%的虛擬世界，那么ar就是以現(xiàn)實(shí)世界的實(shí)體為主體，借助于數(shù)字技術(shù)幫助消費(fèi)者更好地探索現(xiàn)實(shí)世界和與之交付。
vr和ar的區(qū)別：
簡單來說，虛擬現(xiàn)實(shí)（vr），看到的場景和人物全是假的，是把你的意識代入一個虛擬的世界。增強(qiáng)現(xiàn)實(shí)（ar），看到的場景和人物一部分是真一部分是假，是把虛擬的信息帶入到現(xiàn)實(shí)世界中。
mr（mix reality），混合現(xiàn)實(shí)
將真實(shí)世界和虛擬世界混合在一起，來產(chǎn)生新的可視化環(huán)境，環(huán)境中同時包含了物理實(shí)體與虛擬信息，并且必須是實(shí)時的。mr的兩大代表設(shè)備就是hololens與magic leap。
ar和mr該如何區(qū)分？
在上述定義下，ar往往被看做是mr的其中一種形式，因此在當(dāng)今業(yè)界，很多時候?yàn)榱嗣枋龇奖慊蛘咂渌?，就把a(bǔ)r也當(dāng)做了mr的代名詞，用ar代替了mr。
再者，從某些概念來講，ar和mr并沒有明顯的分界線，未來也很可能不再區(qū)分ar與mr，mr更多也只是hololens和magic leap出的噱頭。但是現(xiàn)今所謂的ar設(shè)備與mr設(shè)備，從所應(yīng)用的技術(shù)和顯示效果上來說，還是稍稍有所不同的。
cr（cinematic reality），影像現(xiàn)實(shí)
這是google投資的magic
leap提出的概念，主要為了強(qiáng)調(diào)與vr和ar技術(shù)的不同，同樣，其自認(rèn)為與mr也不同，實(shí)際上理念是類似的，均是模糊物理世界與虛擬世界的便捷，所完成的任務(wù)、所應(yīng)用的場景、所提供的內(nèi)容，與mr產(chǎn)品是相似的。
其核心在于，『通過光波傳導(dǎo)棱鏡設(shè)計，magic
leap從多角度將畫面直接投射于用戶視網(wǎng)膜，從而達(dá)到“欺騙”大腦的目的?！痪褪钦f，有別于通過屏幕投射顯示技術(shù)，通過這樣的技術(shù)，實(shí)現(xiàn)更加真實(shí)的影響，直接與視網(wǎng)膜交互，解決了hololens視野太窄或者眩暈等問題。說到底，只是mr技術(shù)的不同實(shí)現(xiàn)方式而已。資料：ofweek可穿戴設(shè)備網(wǎng)
