In the near future, we may be using our eyes to operate our smart－phones and tablets，even when it comes to playing popular games like Fruit Ninja(水果忍者)．
The Gaze Group has been developing eye－controlled computer technology for nearly 20years. But those devices have been firstly designed to help those with disabilities, and are very expensive.
“After a while, we figured out that probably the best way is to go for a mass－market way，”says Gaze's Sune Alstrup Johansen. “Where everybody would have this available. ”
Johansen and some of his colleagues have formed a new company, the Eye Tribe, which is hoping to develop the technology on a mass commercial level.
The technology works with the help of the computing device toward the user's face. After making sure of the user's eye movements, the technology is then able to easily find where a person's eyes are moving, and then allow the eyes to control a cursor(光标)．
“Our software can then determine the location of the eyes and know where you're looking on the screen to make sure what you're looking at, ”reads an explanation on the Eye Tribe site.
There has been a gradual change toward hands－free technology in recent years, particularly in the gaming (电玩游戏)world. Recently Xbox released (发布) the Kinect device, which lets users control their Xbox and play certain games using only their
hands, legs and voices. But still, most of these devices have been more of a gimmick than a practical way to use one's hands to control a mobile device. Johansen said a replaceable filter(滤光器) would be a cheap, convenient way for most consumers.
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye－controlled technology more available and less expensive will have similar benefits for physically disabled users.

文章大意：这篇短文主要介绍了未来社会的一种科技发明，用眼睛操作手机或者电脑。一直致力于研究帮助残障人士用眼睛控制电脑技术的公司Gaze Group打算将该技术应用于适合普通用户使用的领域，这样不但能惠及更多人，同时还能明显降低此类技术的使用费用。
1. Which of the following is the main idea of the passage?_C__ A. An introduction of a new device. B．An introduction of smart－phones.
C．An introduction of eye－controlling technology. D．An introduction of a new technology for the disabled.
解析：主旨大意题。根据第一段首句“In thenear future，we may be using our eyes to operate our smart－phones and tablets，”及下文描述，可知本文主要介绍了一种用眼睛操作手机或者电脑的技术。
2．The underlined word “gimmick” probably means_A__. A. a trick C. a lie
B．a way D．a dream
解析：词义猜测题。联系下文“more...than a practical way to use one's hands to control a mobile device.”可知此处指的是大部分这些装置都是一种噱头(即骗人的把戏)。
3．According to the passage，we can learn that_C__.
A．the eye－controlled technology was first developed for the blind B．the present development of the technology will bring no good C．there is no such phone as we can use only with our eyes at present D．the eye－controlled technology is only intended for the disabled people 解析：细节理解题。A选项与第二段中的句子 “Butthose devices have been firstly designed to help those with disabilities，”不符，“这些设备最早是为残疾人设计的”；而根据倒数第三、四段可知用眼睛操作的电脑不可能是为盲人设计的。根据短文第一段“In the near future，we may be using our eyes to operate our smart－phones and tablets，”可知目前我们还没有这样一部用眼睛控制的电话。
