Tens of thousands of drone (无人机)owners will have to register their devices for the first time under regulations designed to safeguard privacy.
Rules introduced yesterday require all drones that are fitted with cameras to be logged with the Civil Aviation Authority (CAA). Anyone who fails to do so faces being taken to court and fined up to £1,000. Drones heavier than 250g already have to be registered with the CAA, which costs £9 and must be renewed annually, but the new measures extend this requirement to all devices, including the lightweight models that are used by hobbyist pilots.
The move comes after sharp rise in the number of drones bought by enthusiasts or those operating them for commercial reasons, such as to inspect infrastructure or for photography and filming.
However, the rise has prompted concerns over privacy, with fears that drones are being used to spy on private residences and other buildings. It has also led to an increase in the number of near-misses between drones and other aircraft, including commercial passenger jets. The latest figures show 531 near-misses involving drones were logged in the past decade, including 125 recorded in 2019.
By law drones are supposed to be operated within an operator's line of sight. They have to remain below an altitude of 400ft to avoid interfering with aircraft and flown at least 164ft away from people and buildings. The government has already toughened up regulations in recent years. This includes requiring all operators to pass an online test before being allowed to fly devices. Other changes to the regulations include allowing drones that weigh up to 25kg to be operated, compared with a previous limit of 20kg.
Devices will also fall into three new categories of risk --high, medium and low -- depending on how they will be flown. Low-risk drones, including those typically used by hobbyists, will have operational limitations but will not need authorisation (授权)for flights. Authorisation is needed for larger medium-risk and high-risk drone flights, which are typically carried out in more complex environments, including those beyond the operator's line of sight, which is banned under normal circumstances.
Christian Struwe, the director of public policy, said of the new regulation: "It simplifies different processes and allows customers to travel from country to country without having to worry about different rules in different foreign locations.”

On May 31, a key meeting of the Communist Party of China unveiled a policy that would allow all couples to have up to three children.
The move is expected to maximize the population's role in driving economic and social growth, since this is a critical time for China to transform the world's most populous country into a powerhouse(强国)with a quality workforce, according to the National Health Commission.
The three-child policy is also expected to prevent the decline in the nation's birthrate and address the challenge of a rapidly aging population, China Daily reported.
China's annual number of newborns has fallen for four years in a row. The country's total birthrate—the average number of children born to each woman—stood at 1.3 in 2020. The number is below the rate of 2.1 that would maintain a stable population, according to the National Bureau of Statistics.
The declining birthrate has also brought a sharp increase in the proportion of the population aged 60 or above, rising from 10.3 percent to 18.7 percent in the past decade. An increasingly elderly population will increase the cost of labor and the pressure on the social security net. It also means there will be a lack of young labor force. Therefore, it's not good for economic growth, according to Chen Youhua, a professor at Nanjing University.
In fact, the new birth policy is a step to further relax the family planning policy. The one-child policy was introduced in the 1970s and aimed to control the fast-growing population. Then in 2013, China allowed couples to have a second child if either parent was an only child, and in 2016, all couples were allowed to have two children.
However, not all people have shown their support for this latest policy. Many couples complained about the rising costs of raising a child. A netizen named Qinfeng commented, "High cost of education and both the physical and mental exhaustion stopped me from having more than one child." Also, many women are reluctant(不情愿的)to give birth because that could mean sacrificing their career prospects, according to Mu Guangzong, a professor at Peking University.
In that case, Mu noted that it is better to implement supporting measures with the three-child policy, such as more preferential(优惠的)policies for couples that would ease their parental burden.

When asked to comment on Zhang’s case at a press conference, Yao Hongwen, spokesman for the National Health and Family Planning Commission(NHFPC), said “Every citizen is equal before the law and nobody is allowed to have privileges(特权) to give birth to more children than allowed.”
Yao’s comment came after media stories claimed that Zhang had remarried and fathered a total of seven children: one with his former wife, three with his present wife, Chen Ting, and another three from two lovers.
“The NHFPC’s attitude towards citizens’ birth violations(违法) is consistent and clear. Every Chinese citizen should obey and safeguard the seriousness of laws and regulations.” NHFPC spokesman Yao Hongwen said.
China’s family planning policy, introduced in the late 1970s to slow down the country’s growing population, limits most urban couples to one child and most rural couples to two. The policy was recently relaxed, allowing couples to have two children if one of them is an only child.
Those who break the policy face severe fines. The amount of the fine is generally several times the yearly annual income of the two spouses(配偶). Some media calculations put the fine that Zhang may face at as much as 160 million yuan(over $26 million).
Zhang’s birth case has caused criticism online about famous people who have more children than the policy allows.
In an open letter on December 1, Zhang admitted that the couple has two sons and daughter and they are willing to accept investigation and punishment according to China’s laws and regulations. He apologized to the public.
However, the letter denied that Zhang had lovers and was father to as many as seven children from various mothers.
Zhang, one of the “fifth generation” of Chinese filmmakers, made his first directorial work in 1987 with “Red Sorghum” and has won a number of award worldwide. He was chief director of the opening and closing ceremonies of the Beijing Olympic Games.

【推荐3】French children are saying “Hello” to the new academic year and “Bye” to their cell phones during school hours. That’s because a new law has come into effect which bans phone use by students up to the age of 15. The rule, which follows a campaign promise by French President Emmanuel Macron, also bans tablets and smart watches.
The ban ıs also in place at break times with exceptions in cases of emergency and for disabled children, the French Education Ministry said in a statement. In emergencies, students can ask their teachers for permission to use their phones. Meanwhile, high schools can voluntarily carry out the measure.
Education Minister Jean-Michel Blanquer said the new rules aim to help children focus on lessons, better socialize and reduce social media use. The ban is also designed to fight online bullying and prevent thefts and violence in school. Blanquer has claimed the rule would improve discipline among France’s 12 million school students, nearly 90% of whom have mobile phones. “Being open to technologies of the future doesn’t mean we have to accept all their uses,” Blanquer said in June as the bill was going through in Parliament.
As for carrying out the ban, it’s up to individual school administrations to decide how to put through the ban. School principals can decide to store students’ phones in lockers or allow them to keep them, switched off, in their backpacks. The law allows teachers to take away the phones until the end of the day in case of someone disobeying the bans.
Jacqueline Kay-Cessou, whose 14-year-old son, David, is entering eighth grade at the Camille See International School, told the reporter she was happy to hear of the ban. “It’s fantastic news. It’s something I’ve wanted for years,” Kay-Cessou said. “I think phones are socially harmful. Kids can’t think and sit still anymore and it’s highly addictive.”

【推荐1】Brothers Ayaan and Mickey Naqvi, who live in Shelton, Connecticut, were decorating their family Christmas tree last year when one of their favorite ornaments(装饰品)was destroyed. While the ornament was beyond repair, from its broken pieces sprang a bright idea: What if there was a better way to hang ornaments so they’d be truly secure? From that, the Ornament Anchor(装饰锚)was born.
Using a special system, Ayaan created the model and presented it for a school project. The reception(反响)was overwhelmingly favorable-so favorable in fact, the boys quickly turned their invention into a potential money-making product.
This wasn’t the boys’ first commercial invention: A previous invention landed the pair and their family on a TV programme Shark Tank. While they didn’t cut a deal, it was a true learning experience.
From $1,000 in sales in six hours at a local Christmas trade show, the Ornament Anchor went on to be displayed on Good Morning America. In one year, the brothers’ invention has brought in more than $250,000.
After their success, Ayaan and Mickey are determined to pay their good fortune forward by contributing 10% of their profits to local animal shelters. “Ever since I was super young, I’ve had a fascination with all of life’s creatures,” Ayaan explained. “My goal is to help as many animals in need as I can.”
The boys admit that starting a new business in 2020 had its challenges. While they are enjoying their success, adjusting to distance learning due to the coronavirus lockdown isn’t easy.
Through the difficult times, they say they’ve just tried to take things one step at a time and keep a positive attitude because that-along with the love and support of their family-are what keeps them anchored(稳定).

【推荐2】The words “protect animals” appear everywhere in books and on screens since some animals are in danger of dying out. But sometimes the reality can be a little different from what people read or watch.
About 300 black bears were killed in Florida, the US, in October, 2015. It’s been the first bear hunt since 1994.
Animal protection groups were against this decision. But local officials explained that the black bear population had grown to 3,500 and become a menace to local people. In the past two years, bears have hurt at least four people in Florida.
This brings an old question back into the spotlight — which is more important, protecting animals or protecting people’s interests(利益)?
This question is asked in other countries too. In Switzerland, a wolf was sentenced to death by the Swiss government months ago. This is because the wolf killed 38 sheep and local people lost a lot of money. Days ago in China, three old men were arrested for killing a serow (鬣羚), a protected species. But they insisted they didn’t know about this and killed the animal because it ruined their crops.
However, these stories don’t always mean that animal protection stops due to human interests, especially involving economic development. A man named Zhou Weisen set up a wild animal base in Guilin, Guangxi. He saved over 170 tigers and 300 bears. But his base also offered jobs to local people.
“There may never be a standard answer to the question of whether we should give more attention to the environment or human development,” said Robert May, a British biologist at Oxford University. “But we shouldn’t push either one to the side, as the future is hanging in the balance.”

【推荐3】A huge block of ice has collapsed from the Marmelada mountain in Daly, leaving at least 5 dead and 10 wounded. All the mountain rescue stations in the area have been activated and the injured have been hospitalized in several hospitals, the national Rai TV reported, citing the Alpine Rescue.
“This summer risks being the perfect storm for glaciers(冰川),” said Ginvanni Baccolo. He is an environmental scientist and glacier expert at Milan-Bicocca University. Baccolo noted a lack of winter snow and a hot start to the summer affecting glaciers. “Nobody could have expected a glacier like the Marmolada to react like this,” he told Reuters. Temperatures on the normally freezing Marmolada reached 10 degrees Celsius on Saturday, Veneto area governor Luca Zaia said.
In fact, Italy has experienced early and severe summer heat. Glaciers in Europe’s Alpine Mountains, including the Dolomite Mountains, are becoming more unstable and dangerous because of rising temperatures linked to climate change.
“High altitude glaciers such as the Marmolada are often steep(陡峭的) and relying on cold temperatures below zero degrees Celsius to keep them stable.”said Poul Christoffersen. He is a professor at the University of Cambridge who studies glaciers. Christoffersen said that climate change melts more water, which releases heat that warms up the ice if the water re -freezes. He added that a worse effect would be the lifting of the glacier forn the rock below, causing a sudden unstable collapse.
Baccolo made suggestions to the climbers heading into the mountains to escape the summer heat. “The invitation I want to make to those who go to the high mountains this summer is to use much more carefulness,” he said. “The problem is that it may no longer be enough to read the signs from the glacier that have been read so far,” he added.

【推荐1】At the age of 86, agriculture teacher Gerald Bonds has seen plenty of crises during his career. He sees no reason to leave the profession over the coronavirus crisis. Bonds is in his 58th year of teaching at Farmington High School in Farmington, New Mexico. Like most teachers in his state, he has been instructing his students from home, which he truly dislikes.
“I hate it. I want to see the students face to face and talk to them,” Bonds told reporters with The Associated Press. Some teachers have retired early or taken leave because of the difficulties of distance learning and the health risks of in-person teaching. But many longtime instructors like Bonds are choosing to stay.
The states of New Mexico and Maine have the oldest teachers in the country, with one in four older than 55. That information comes from a 2018 study of teachers and school leaders by the National Center for Education Statistics. Almost six percent of New Mexico’s educators are 65 or older, notes the New Mexico Public Education Department.
With few exceptions, New Mexico’s schools have been providing only distance learning. So far, this has saved many teachers from dealing with the health risks of being in classrooms with students. Ryan Stewart is the New Mexico Education Secretary. He told the AP that his state is making health and safety number one. Teachers whose health is at a high risk can ask for low-contact or no-contact teaching work, he said. For some parts of the state, this will cause a shortage of teachers and make it harder to return to in-person learning, he noted.

【推荐2】One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?
Listen - Listen when they are talking. Don’t say anything unless they ask you a question. Sometimes it’s not necessary for you to have anything to say; they just need someone to talk to about their feelings.
Help them - If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don’t do everything they want you to do. Try to take an extra (额外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.
Be there for them - Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can’t stay with me at my worst, you are sure not to deserve (值得) to be with me at my best.” Always remember this! If you don’t want to stay with your friends when they’re in hard times, then you don’t deserve to be with them when they’re having a good time!
______ Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you’ll remember these things when you’re all old!

【推荐1】I made my decision to start my own company and leave my stable position after attending a regional sales meeting. The vice-president of our company delivered a speech that changed my life. He asked us. "If genie(精灵)would grant you three wishes what would they be?" After giving us a moment to write down the three wishes, he then asked us. "Why do you need genie?" I would never forget the power I felt at that moment.
I realized that everything I had accomplished had prepared me for this moment. I was ready and did not need a genie's help to become a professional speaker.
When I tearfully told my boss my plans, this incredible leader whom I respect so much replied, "Go ahead with reckless abandon and it will pay off."
Having made that decision, I was immediately tested. One week after I quit mine, my husband was laid off(解雇)from his job. We had recently bought a new home me and needed both incomes to make the monthly mortgage payment and now we were done to no income. It was tempting to turn back to my former company, knowing they wanted me to stay, but I was certain that if I went back, I would never leave. I decided I still wanted to move forward rather than end up with a mouth full of "if onlys" later on. A motivational speaker was born.
When I held fast to my dream, even during the tough times, the miracles really began to happen. In a short time period my husband found a better job. We didn't miss a mortgage payment. And I was able to book several speaking engagements with new clients. I discovered the incredible power of dreams. I loved my old job, my peers and the company I left, but it was time to get on with my dream. To celebrate my success, I had a local artist paint my new office as a garden.

【推荐2】After almost a year of saving from shopping and vacationing, you find the numbers reflected by your bank account meet your heat’s desire. Now the most important question comes what to do with the earnings? Should you fulfill dreams of the present, or keep saving it for a rainy day?
Our elders always try to teach us the value of money and its uncertainty. One may be on a winning situation now, but it will not always be so. One will have days when there will be no sunshine but only rain, and their luck will hide behind those thick grey clouds. Save for those rainy days, they say. Do not spend too much, live within a budget, stay away from credit no matter how small and save for the future. Since the very first time we earn our own money from a summer job or earn our first salary, the lessons start.
In fact, the pocket money that we receive when we are children starts the process of learning how to best manage one’s manage one’s money. Future, future, future, that’s all they talk about, but what about the present? What about our current desires, wants and needs? Wasn’t our present once our future?
One day when I have enough money, I will buy myself a car. One day my luck will shine. One day I will have enough money to travel the world. Then, once we do earn enough money from saving, tomorrow’s plans start shadowing our present ones.
However, is it wise to keep living for that future? Will we still enjoy or even be able to backpack in our 50s? What will be the use of those professional cameras when pains take over our joints and our mind grows dull? Will our liver be able too handle the meat and alcohol in our advanced age? What if our life ends suddenly? How will we ever enjoy our present if we are constantly living for the future?
I say enjoy the most comfort but also keep enough for your necessities, and stay happy with your present but with a plan for the foreseeable future. Beyond that, life is not in our control and we shouldn’t worry about the unseen. Life is for the living, so live it wisely.

【推荐3】Let’ do some sleep math. You lost two hours of sleep every night last week because of a big project due on Friday. On Saturday and Sunday, you slept in, getting four extra hours. On Monday morning, you were feeling so bright-eyed, and you only had one cup of coffee, instead of your usual two. But dons’ be cheated by your energy: You’re still carrying around a heavy load of sleepiness, or what experts call “sleep debt” - in this case something like six hours, almost a full night’s sleep.
Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get. It’s a deficit(缺乏)that grows every time we skim some extra minutes off our nightly sleep. “People accumulate(积累)sleep debt gradually without being noticed,” says William C. Decent, founder of the Stanford University Sleep Research Center. Studies show that such short-term lack of sleep leads to a foggy brain, worsened vision, and trouble remembering. Long-term effects include obesity(肥胖)and heart disease.A survey by the National Sleep Foundation reports that we’re losing one hour of sleep each night---more than two full weeks of sleep every year.
The good news is that, like all debts, with some work, sleep debt can be repaid. Adding an extra hour or two of sleep a night is the way to catch up on sleep debt. For the long-term lack of sleep, take it easy for a few months to get back into a natural sleep pattern. Go to bed when you are tired, and allow your body to wake you in the morning (no alarm clock allowed). You may find yourself catatonic(有紧张感的)in the beginning of the recovery cycle: expect to have ten hours shut-eye per night. As the days pass, however, the amount of sleeping time will gradually decrease.
So earn back that lost sleep---and follow the orders of your inner sleep needs, and you’ll feel better. “When you put away sleep debt, you become a superman,” says Stanford’s Dement, talking about the improved mental and physical abilities that come with being well rested.
