Question

    A new device (设备) called Orion is helping those who are blind to see. It does this in a new way by helping them experience the world around them.

Jason Esterhuizen lost his eyesight after a car accident. He never thought he would be able to see light or movement again. But now with the movement of a switch (开关), his world suddenly grew brighter.

He says, “I still can’t put it into words. I mean from being able to see absolutely nothing, it’s completely black, to all of a sudden seeing little flickers (闪烁) of light move around.” It is not full or normal sight, but Esterhuizen can move about in the world around him.

The new technology uses several parts. One is a small device placed in the brain. The other parts are a video camera on sunglasses and a processing device that can be carried in a person’s clothes. When the user points the camera, a signal goes to the processor (处理器) and then back to the glasses. The glasses then are in wireless communication with the device in the brain. The information causes a pattern to develop in the part of the brain. The pattern helps users sense or see movement and shapes of light. And it all happens in seconds.

Esterhuizen is one of just two people in the U.S. testing this technology. He says that “I can tell someone moving across the room, walking past me or walking away from me, or it’s a light against the wall. It is just amazing to have some form of functional vision again.” He adds that now he can do everyday activities around his home that he once could not. It is easier to walk outside.

The researchers believe that one day this technology could help people who have lost their vision because of illnesses like diabetes. It may also help those with poor vision or who were born blind.

A.An illness. B.A car accident.

C.A brain damage. D.A genetic problem.

A.He fully regains his sight.

B.He always do daily activities freely.

C.He feels delighted to see the world again.

D.He is the only one to test this technology.

【解析】

这是一篇说明文。文章主要介绍了一种名为“猎户座”的新设备正在帮助那些盲人重见光明。它以一种新的方式帮助他们体验周围的世界。

1.细节理解题。根据文章第二段第1句内容：Jason Esterhuizen lost his eyesight after a car accident.（Jason Esterhuizen在一次车祸后失去了视力。）可知，Esterhuizen是在车祸中失明的。故选B项。

2.细节理解题。根据文章第四段内容：The new technology uses several parts. One is a small device placed in the brain. The other parts are a video camera on sunglasses and a processing device that can be carried in a person’s clothes. When the user points the camera, a signal goes to the processor and then back to the glasses. The glasses then are in wireless communication with the device in the brain.（这项新技术使用了几个部分。一个是放置在大脑中的小装置。其他部分是太阳镜上的摄像机和可以放在衣服里的处理设备。当用户点相机时,信号的处理器，然后回到了眼镜。然后，眼镜就可以与大脑中的设备进行无线通信。）可知，太阳镜可以与大脑中的小装置进行无线通信。故选D项。

3.细节理解题。根据文章第五段第2句内容：He says that “I can tell someone moving across the room, walking past me or walking away from me, or it’s a light against the wall. It is just amazing to have some form of functional vision again.”（他说:“我能分辨出是有人从我身边走过，还是从我身边走开，或者是墙上的一盏灯。再次拥有某种形式的功能性视力真是太神奇了。”）可知，能够拥有功能性视力使他很高兴。选项C：He feels delighted to see the world again.（他很高兴再次看到这个世界。）论述正确。故选C项。

4.主旨大意题。根据文章结构为总分结构，可知，第一段提出了文章的主旨要点：A new device called Orion is helping those who are blind to see. It does this in a new way by helping them experience the world around them.（一种名为“猎户座”的新设备正在帮助那些盲人重见光明。它以一种新的方式帮助他们体验周围的世界。）可知，本文主要介绍了一种新型的帮助盲人重新看到世界的设备。选项C：A new equipment helps the blind see.（一种新设备帮助盲人看东西。）概括了主旨。故选C项。
