人类有“千里眼”的梦想,望远镜就被发明出来了。人类有“顺风耳”的梦想,雷达就被发明出来了。人类想做飞鸟,飞机有了。人类想当嫦娥,载人飞船就有了。科技帮助人类实现了各种“离奇梦想”。这不,帮助我们实现“梦想”的又一项新科技亮相了。它叫“虚拟现实”(Virtual Reality),简称“VR”。它利用电脑或其他智能设备模拟产生立体的虚拟世界。 Human beings have the dream of “Clairvoyance” and the telescope was invented. Human beings have “dreams” dream, the radar was invented. Humans want to do birds, planes have. Human beings want Chang’e, manned spacecraft there. Science and technology have helped people achieve a variety of “bizarre dreams.” This is not yet another new technology that has helped us to realize “Dream”. It’s called “Virtual Reality,” or “VR” for short. It uses computers or other smart devices to simulate a three-dimensional virtual world.
