In 2012, a special kind of glove came out. It was invented to help blind people to learn Braille, which is a special system for the blind to read by touching. Shaking motors (震动马达) are put on each finger of the glove. They can make different sounds to tell a user which letter he is touching. Recently, two British college students have invented another special glove for the blind. It can make the user feel small and quick movements. An ultrasonic sensor (超声波传感器) with a battery is put on the back of the glove. When the user wearing the glove is close to an object (物体), ultrasonic waves (超声波) from the glove are sent out. As soon as they hit the object in front, the waves will return to the glove. Then the waves cause the glove to shake. And the ultrasonic sensor makes different kinds of sounds. The sounds make the user know how far he is from the object.
In the college invention competition, the two students got first prize and won 1,540 pounds. One of the designers said, “Now the ultrasonic sensor on the glove is quite large. We, re going to use the money to develop a smaller and lighter ultrasonic sensor.”

Good morning, everyone! Today, I’m going to talk about inventions.
Inventions are created every day because people would like to make life easier. There are famous inventions like TV and the bicycle. TV provides us with different kinds of information so that we can know more about the world. We watch entertainment programs to relax ourselves. Besides, some learning programs help us with our study.
The bicycle is very useful, too. We go to school or work by bike. It makes no pollution, which is good for our environment. What’s more, bicycle riding is quite good for our health. It’s cheap, too.
Though there have been many great inventions. I wish to invent a kind of pen to help us write more quickly and neatly. When we have problems in doing homework, it will tell us how to solve them.
That’s all. Thank you very much.
