During the National Day holiday, the sky above Shenzhen was lit up by impressive drone(无人机) light shows. This"cyber fireworks" lit up the night, painting a lively picture of Shenzhen as a"City of Miracles, City of Innovation. City of Future". A total of 10197 DAMODA drones took to the sky at the same time, setting two Guinness World Records. So how does the drone light show work?
Before a drone light show begins, drones are usually put on the ground one by one and it would take a lot of time to prepare a show with more than ten thousand drones. To shorten the time, the DAMODA drone company thought of a solution. The company put groups of drones into big boxes with specific QR codes on it. By putting the boxes into correct places, thousands of drones can be ready in a short time and they can go back to their"homes" by scanning the OR codes.
In drone shows, each drone is programmed by a computer to follow its own flight direction, carefully avoiding the other drones. They communicate with neighbouring drones and use sensors(传感器) to keep a certain distance. The position and LED colours change throughout the performance to show different objects in the night sky.
Drone light shows are thought to be more environmentally friendly— and certainly cause less noise and light pollution— than fireworks shows, so lots of big events are turning to them instead of fireworks. Drones can also be reused again and again so they will probably be more popular in the future.
Many libraries charge a late fee(费用). If you return a book after a certain date, you pay a fine. But this might be changing. For public libraries, anyway. Some say these fees stop some people from using the library. And the point of libraries is to make books available. So we asked our readers what they think about late fees. Keep them? Or stop them? Here's what two kids bad to say.
☑ Do you use the library?
☑ Have you had to pay for returning a book late?
Fiona Sheehy, 9, NY | Libraries should charge late fees. Do you enjoy the library? You can discover new books there. But you might not get a chance if kids don't return them. Paying a fee will teach kids to be responsible. This will help when they get older and have a job. Some borrowers return books late. The money can be used to make the library a better place. So late fees are a must. |
Aiden Robinson, 10, CA | Libraries should not charge late fees. Some people just need time to finish the book. Late fees at some libraries have reached $50 for a couple of books. Many kids can't afford that, And a late fee doesn't make people more responsible. What works is sending reminders. Or libraries can provide more overnight service for book return. I learned from the news that this helped in Brooklyn, New York. |

How much pocket money do you get from your parents each week? British researchers did a survey of 1,204 children between 8 and 15 years old. According to the reports, they are getting less and less pocket money.
In 2010 | They found the average amount of pocket money for British kids was about 5.89 pounds (62 yuan) a week. |
In 2009 | It was 6.24 pounds (66 yuan). |
In 2007 | It was 6.58 pounds (69 yuan). |
In 2003 | Parents gave children an average of 5.79 pounds (61 yuan) a week. |
However, children are not too worried about it, according to the survey. Almost half of them believe they get the right amount. Only 42 percent say they would like to have more pocket money. Most kids like to compare their pocket money with their friends. In the survey, 37 percent believe their friends get more money than they do.
Although they are receiving less pocket money than before, most British kids still keep the good habit of saving, according to the survey.
10% | They save all their pocket money. |
25% | They save at least half. |
35% | They will save money to buy something they really want. |
"It is good to develop the habit of saving at a young age," said Flavia Palacios Uman, one of the researchers. "You will benefit later in life because your savings will add up over time."
