一、课文原文及逐段翻译
第 1 段（定义与意义）原文：Imagine having the opportunity to sing together with hundreds of other people while you are at home alone. You can do this in a virtual choir. Virtual choir members record themselves while they perform alone on video. These videos are uploaded onto t he Internet, and then they are put together into one video that you can see online—a virtual choir. Anyone can take part in a virtual choir from anywhere—all you need is a video camera and an Internet connection. You do not even need a studio. A virtual choir helps connect ordinary people together. Many people do not have close friends or contacts who have the same interest in music. Many others do not have the chance to join a local choir. A virtual choir enables them to add their voices to those of other individuals and become part of the global community. It has proved to be a positive influence on the lives of many people. As one virtual choir member said, "Music helps me to ... forget my problems. With music, I become someone else."
译文：想象一下你独自在家就有机会与数百人一起歌唱。你可以在虚拟合唱团中做到这一点。虚拟合唱团成员在单独录制视频的同时进行录制他们自己。这些视频被上传到网上，然后被整合成一个你可以在线观看的视频——一个虚拟合唱团。任何人从任何地方都可以参加虚拟合唱团——你所需要的只是一台摄像机和互联网连接。你甚至不需要录音棚。虚拟合唱团有助于将普通人联系在一起。许多人没有对音乐有相同兴趣的亲密朋友或联系人。许多其他人没有机会参加当地的合唱团。虚拟合唱团使他们能够将自己的声音加入到其他人的声音中，并成为全球社区的一部分。事实证明，这对许多人的生活产生了积极影响。正如一位虚拟合唱团成员所说："音乐可以帮助我……忘记我的烦恼。在音乐的帮助下，我变成了另一个人。"
注：脚注：原文此处因排版换行，单词 "the" 被断开为 "t" 与 "he"，故文本显示为 "onto t he Internet"，实际应为 onto the Internet。
第 2 段（创意起源：埃里克·惠塔克）原文：The virtual choir was the idea of award-winning composer and conductor Eric Whitacre. Born in the USA on 2 January 1970, Whitacre began studying music at the University of Nevada in 1988. He fell in love with Mozart's classical music when he sang for the university choir. Moved by this music, he said, "It was like seeing color for the first time." He graduated from university in 1995, and then received a master's degree in musical composition from the Juilliard School in New York in 1997. Over the next 10 years, Whitacre's original compositions began to become quite popular among choirs and singers. This led to the creation of the virtual choir.
译文：虚拟合唱团是屡获殊荣的作曲家兼指挥家埃里克·惠塔克的创意。惠塔克于1970年1月2日出生在美国，1988年开始在内华达大学学习音乐。当他为大学合唱团唱歌时，他爱上了莫扎特的古典音乐。他被这段音乐打动了，他说："那种(兴奋的)感觉就如同第一次看见色彩一样。"他于1995年大学毕业，随后于1997年获得纽约茱莉亚音乐学院音乐创作硕士学位。在接下来的十多年里，惠塔克的原创作品在合唱团和歌手中开始流行。这促使了虚拟合唱团的创建。
第 3 段（发展历程：从首个到全球现象）原文：In 2009, Whitacre received a video of a girl who was singing one of his works. Inspired, he asked his fans to make videos, which he then joined together into one performance. His first virtual choir, "Lux Aurumque", had 185 singers from 12 different countries. It has received millions of views on the Internet. Since then, the virtual choir has become a worldwide phenomenon. Whitacre's next effort was the Virtual Youth Choir for UNICEF, which was first seen on stage on 23 July 2014 in the UK. Altogether, 2,292 young people from 80 countries joined in to sing Whitacre's song "What If".
译文：2009年，惠塔克收到了一个女孩在演唱他的作品的视频。受到启发，他让歌迷们制作视频，然后将视频合并到一个表演中。他的第一支虚拟合唱团《金色光芒》有来自12个不同国家的185位歌手。它在上收到数以万计的浏览量。从那时起，虚拟合唱团已成为一种全球现象。惠塔克的第二个壮举是打造联合国儿童基金会"虚拟青年合唱团"，该合唱团于2014年7月23日在英国首次亮相。总共有来自80个国家的2292名青年参与演唱惠塔克的歌曲《假如》。
第 4 段（总结升华）原文：The virtual choir is a wonderful way for people around the world to sing with one voice and thus make the world a better place.
译文：虚拟合唱团是让全国各地的人用同一个声音唱歌，从而使整个世界变得更美好的绝妙方式。

五、长难句拆解
【原句 1】Virtual choir members record themselves while they perform alone on video.
【主干】members record themselves.
【分层】while they perform alone on video 为时间状语从句，while 表"当……时"，on video 作状语。
【译文】虚拟合唱团成员在单独录制视频时进行自我录制。
【考点】while 引导时间状语从句；record 此处为及物动词"录制"。
【原句 2】These videos are uploaded onto the Internet, and then they are put together into one video that you can see online—a virtual choir.
【主干】videos are uploaded, and they are put together into one video.
【分层】and 连接两个并列被动句；that you can see online 为定语从句修饰 one video；破折号后 a virtual choir 为 one video 的同位语。
【译文】这些视频被上传到网上，然后被整合进一个你可以在线观看的视频——一个虚拟合唱团。
【考点】被动语态并列；定语从句；同位语解释。
【原句 3】A virtual choir enables them to add their voices to those of other individuals and become part of the global community.
【主干】A virtual choir enables them to add ... and (to) become ...
【分层】enable sb to do 结构；and 连接两个并列不定式 to add 与 (to) become；those 指代 those voices。
【译文】虚拟合唱团使他们能够把声音加入其他人的声音中，并成为全球社群的一部分。

【译文】惠塔克于1970年1月2日出生在美国，1988年开始在内华达大学学习音乐。
【考点】过去分词作状语（Born ...）；begin doing。
【原句 5】Moved by this music, he said, "It was like seeing color for the first time."
【主干】he said ...
【分层】Moved by this music 为过去分词短语作原因状语，相当于 Because he was moved by ...；引号内为直接引语，like seeing color 中 like 为介词，后接动名词。
【译文】他被这段音乐打动，说："那种感觉就如同第一次看见色彩一样。"
【考点】过去分词作原因状语；like + 动名词。
六、语法点清单
1. 过去分词作状语（表时间 / 原因）
Born in the USA ...（出生于……之后）、Moved by this music（被音乐打动，表原因）、Inspired, he asked ...（受到启发，表原因）。过去分词与主语构成被动 / 完成关系，常可还原为 after / because 引导的从句。
2. 定语从句
contacts who have the same interest（who 指人）；one video that you can see online（that 指物）；a girl who was singing ...；Virtual Youth Choir ... which was first seen ...（which 非限制性定从）。注意区分限制性 / 非限制性。
3. enable sb to do 结构
A virtual choir enables them to add ... and become ...。enable 后接宾语 + 不定式，类似 make / let 但 enable 必须用 to do。
4. 同位语
one video — a virtual choir；Whitacre's next effort was the Virtual Youth Choir for UNICEF。同位语对前文名词作解释或补充。
5. 现在分词作定语
award-winning composer 中 winning 为现在分词作前置定语，表"获奖的"。
6. 并列结构
全文大量使用 and / or 连接并列谓语、并列宾语与并列句，如 uploaded ... and then ... put together，是说明类语篇的骨架。
七、逻辑链
总起（第1段）：是什么 + 怎么参与——定义虚拟合唱团、上传视频合成、人人可参与、意义（连接普通人、积极影响）
↓
起源（第2段）：谁想出的——惠塔克生平：出生、学音乐、爱上古典乐、毕业、作品流行 → 催生虚拟合唱团
↓
发展（第3段）：如何壮大——2009 受女孩视频启发 → 首个《Lux Aurumque》185人 → 全球现象 → 2014 联合国青年合唱团 2292人
↓
总结（第4段）：升华主题——用同一个声音歌唱，让世界更美好
注：脉络：概念介绍 → 人物溯源 → 事实印证 → 价值升华，是典型的"说明 + 叙事"结构，适合做人物 / 科技类说明文范本。
