Question

When you pull the headset over your eyes and the game begins， you are transported to a tiny room with white walls．Your task is to break out of the room， but you cannot use your hands， joystick or game pad．You must use your thoughts．

You turn toward a ball on the floor， and your brain sends a command to pick it up．With another thought，you send the ball crashing into a mirror， breaking the glass and revealing a few numbers scribbled on a wall．You mentally type those numbers into a large keypad by the door．And you are out．

Designed by Neurable，a small startup founded by Ramses Alcaide，an electrical engineer and neuroscientist （神经科学家），the game offers a way of selecting items in a virtual world with your thoughts．

Having a headset with virtual reality goggles （眼镜） and sensors （传感器） that can read your brain waves，it will be a few years before this device comes into the market． And it is limited in what it can do．But it works．I recently played the game，titled Awakening，when Alcaide and two Neurable employees passed through San Francisco， so did a few hundred others this month at the Siggraph computer graphics conference in Los Angeles．

Driven by recent investments from the US government， many startups and bigger companies are working on ways to mentally control machines， looking for smoother ways to use virtual reality technology．

"Neurotechnology has become cool，" said Ed Boyden， a professor at the MIT Media Lab who advises one of those startups．

At Neurable， Alcaide and his team are pushing the limits of EEG （脑电图） headsets． Although sensors can read electrical brain activity from outside the skull， it is very difficult to separate the signal from the noise． Using computer algorithms （算法） based on Alcaide's research， Neurable works to read activity with a speed and accuracy that's not usually possible．

The algorithms learn from your behavior．Before playing the game，you train them to recognize when you are focusing your attention on an object．A pulse of light bounces around the virtual room，and each time it hits a small colored ball in front of you，you think about the ball．At that moment，when you focus on the light and it stimulates your brain，the system reads the specific signals of your brain activity．

B. The limits of EEG headsets

C. Sensors that read brain signals

D. Recent investments on virtual reality technology

Answer

1. B

2. D

3. A

【解析】

本文是一篇说明文。讲述的是很多公司都在研发精神控制机器技术，最终你可以用你的头脑控制一个游戏。

1.细节理解题。根据第二段最后一句You mentally type those numbers into a large keypad by the door．And you are out.可知，在键盘上输入你想的数字，就能出去。故选B。

2.细节理解题。根据第五段Driven by recent investments from the US government， many startups and bigger companies are working on ways to mentally control machines， looking for smoother ways to use virtual reality technology.可知，很多新创公司和大公司都在研发精神控制机器技术。故选D。

3.主旨大意题。根据最后一段…you think about the ball．At that moment，when you focus on the light and it stimulates your brain，the system reads the specific signals of your brain activity"以及全文内容可知，本文讲述的是精神控制机器技术的发展以及未来你可以用你的头脑控制一个游戏。故选A。
