7-Wednesday 科学研究 205词

题材： 科学研究　 词数： 205　 建议阅读时间： 4分钟

阅读下面的短文，选择正确答案。

We see with our eyes and taste with our tongues．Ears are for hearing，skin is for feeling and noses are for smelling．Would anyone say that ears can smell，or that tongues can see？Actually，yes．Paul Bachy-Rita，a scientist at the University of Wisconsin，believes that the senses can be changeable．For example，a tongue can be used for seeing．The brain，as we know，is a complex organ．Even when part of it is hurt，it will try to carry out the same function by sending the function to another area of the brain．

A college student was asked to take part in an experiment．In the experiment，his eyes were covered with a small video camera．The camera was connected to a long plastic line which went into his mouth．A computer would change the video' picture into signal．The picture would travel through the plastic line as an electric current，reaching the electrodes （电极板） inside the student's mouth．The scientist would roll a ball towards his right side，left side，or centre，and the student would have to catch it．When the scientist rolled the ball，pain passed over the student's tongue．From the position of the pain on the tongue，the student reached out his hand and caught the ball．

If the brain can see a ball through a camera and a wet tongue，blindness and deafness can be overcome.

参考译文

我们用眼睛看，用舌头尝。耳朵是用来听的，皮肤是用来感觉的，鼻子是用来闻的。有人会说耳朵能闻、舌头能看吗？事实上，真有人这么说。威斯康星大学的科学家保罗·贝奇-利塔认为，感官是可以改变的。比如，舌头就可以用来看。正如我们所知，大脑是一个复杂的器官。即使它的部分区域受损，它也会尽力把这一功能转移到其他区域以继续执行。

一名大学生应邀参加了一项实验。在该实验中，他的眼睛被罩上了小型摄像机。这台摄像机通过一条长塑料导线通进嘴里。一台电脑将把摄像机拍到的图像转换为信号。这样，图像就可以像电流一样通过塑料导线传输到放在学生嘴里的电极板上。科学家把一只球分别向学生的右边、左边或中间滚去，而学生必须抓住它。当科学家把球滚出时，痛感传输到学生的舌头上。根据痛感的位置，学生伸手抓住了球。

如果大脑能通过摄像机和湿漉漉的舌头看到球，失明和失聪的问题就可以解决了。
