We see with our eyes and taste with our tongues（舌头）．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 Bach-V-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（大脑）,as

we know，is a complex organ（复杂的器官）．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's picture．The picture would travel through the plastic line as an electric current（电流），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（位置）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（克服）．

Hello Sandy,
We have just returned form our holiday. We went with our friends，Edward Smith and his wife Tina, to the Yorkshire Moors. It is a beautiful natural park. There are lots of places to walk on the tops of the hills，miles of grassland with no people，just sheep and birds.
Edward had just come out of hospital and he could not walk as far as before. However, this meant that we walked in the mornings, and then stopped at a restaurant for lunch each day before returning to the place we lived in. Edward and I slept in front of the fire all afternoon, while the ladies went for another walk. Very pleasant!
I took lots of photos from the place we lived in, across the valley (山谷）below us, of the morning sunrise, and the mist(迷雾）in the valley. Also, in England, the old steam-powered trains are very popular. I took many photos of the train.
Yesterday we had the first snow of this winter. It is very early. We usually have snow in January. It rained all day, then snowed in the evening .Today we have bright sunshine! Both Jenny and I are well. I don’t know if I told you, in the last e-mail , that Jenny is now working in a hotel. Although she has to work hard, people there are nice, and she is enjoying the work.
Please write to us to tell us your news.
Yours,                                                                  Victor
