(From Shenzhen Special Zone Daily, Feb. 13) Some white robots were seen delivering(传送) food at a park in Nanshan District. These robots are used because the park director doesn’t want too many people to wait for lunch so as to avoid the people- to-people transmission(传播) of COVID-19. These robots were developed by Candela (Shenzhen) Technology Innovation Co. Ltd.

A group of small robots (called Candles) deliver food inside office buildings while another group (called Sunnys) transport the meals between buildings outdoors.

Candle robots can work with gate machines and elevators and will not get in people’s way. The robot makes a phone call or texts a message to orderers after arriving at their floor. Thirty Candles have been put into use. They can provide 500 to 1,000 meals each day with at least 60 meals at a time. The robots will be disinfected(消毒) six times a day.

Sunnys work outdoors and are able to avoid running into walkers, bikes and other things. After arriving at the place, a Sunny will give food boxes to a Candle for indoor delivery.

The company also developed a group of medical robots after the outbreak to support hospitals in Wuhan, Beijing and Shenzhen. “Unmanned delivery is very necessary now. We hope these robots, and the technology, can bring comfort to people,” said He Zhiwei, general manager of Candela.

The Internet is becoming important in our life. How much do you know about it? The following questions and their answers will help you to know more about the Internet.

The Internet is a large, world-wide collection (聚集) of computer networks. A network is a small group of computers put together. The Internet is many different kinds of networks from all over the world. These networks are called the Internet. If you have learned to use the Internet, you can have a lot of interest on the World Wide Web.

The World Wide Web has been the most popular development of the Internet. It is like a big electronic book with millions of pages. These pages are called homepages. You can find information about almost anything in the world on these pages. For example, you can use the Internet instead of a library to find information for your homework. You can also find information about your favourite sport or film star, talk to your friends or even do some shopping on the pages. Most pages have words, pictures and even sound or music.

Electronic mail (e-mail) is a way of sending messages to other people. It’s much quicker and cheaper than sending a letter. If you want to use e-mail, you must have an e-mail address. This address must have letters and dots and an @ (means “at”). For example: Lily @ Yahoo.com. Write a message, type a person’s e-mail address, and then send the message across the Internet. People don’t need to use stamps, envelopes or go to the post office because of the invention of the Internet. Quick, easy and interesting — that’s the Internet.
