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．
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years．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 world．Recently Xbox released 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 accessible and less expensive will have similar benefits for physically disabled users.

【小题1】Which of the following is the main idea of the passage?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．【小题2】The underlined word“gimmick” probably means .A．a trickB．a wayC．a lieD．a dream【小题3】According to the passage，we can learn that .A．the eye-controlling technology was first developed for the blindB．the present developing 0f the technology will bring no goodC．there is no such a phone as we can use only with our eyes at presentD．the eye-controlling technology is only intended for the disabled people【小题4】This passage is probably taken from .A．an experiment report B．a science fictionC．a school textbookD．a science websiteC

(答案→)C 解析：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。【小题1】根据第一段In the near 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。故选C。【小题2】联系下文a practical way to use one’s hands to control a mobile device．描述，可知此处指的是大部分这些装置都是一个骗人的把戏。故选A。【小题3】根据短文第一段描述，可知目前我们还没有这样一部用眼镜控制的电话。故选C。【小题4】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。根据短文最后一段For more articles on modern science，please CLICK here．描述，可知这是一篇网上的文章，故有可能来自一家科学网站。选D。

这个问题我还想问问老师呢
