Last year, a special kind of glove came out. It was invented to help bind 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  (发出). 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.

Canada Day

      Since 1982, July 1st has been officially known as Canada Day. Canadians of all ages take part in this festival across the country.
　　Canada Day is the year's biggest national party. In many towns and cities, the government organizes a lot of events, often outdoors. These include parades（游行）, concerts, festivals, firework displays and ceremonies for new Canadian citizens（公民）. The celebrations often have a patriotic mood. Canada's national flag, a symbol for Canada Day, can be seen everywhere and a lot of people paint their faces red and white, which are Canada's national colors. The celebrations in Ottawa, Canada's capital city, are especially grand and exciting.
　　In the province of Quebec, many home rentals（租赁）start on July 1st and last for exactly one year, and many people in Quebec spend Canada Day moving from one house to another. So in Quebec, Canada Day is also known as Moving Day.
　　Many organizations, businesses and stores are closed this day. Only some bookstores, ho spitals and gas stations may be open. Post offices are closed, too. As Canada Day falls in the Canadian summer holiday period, all schools are closed as well. In some areas, special services are provided for large events. The concerts, parades and festivals may cause some traffic jams.
