In the past, if you wanted to learn something new, you might have to go to school or some other places to attend a class. But online learning changed that. Last year, the online learning market was worth $1,665 billion. In the latest survey of Global Shapers, among 25,000 young people across the world, 77.84% of them reported having taken online courses.
However, the growth of online education has not been without challenges. Since its early start in the 1960s, online education has been always criticized (批评) for being short of quality control, especially for being short of high-quality teachers. It’s also been said that online learning keeps students away from some of the advantages of being in a classroom, such as the teacher-student communication face to face. Besides, being in a classroom doesn’t always demand the Internet connection and the electricity supply.
Regardless of these concerns, online education has made great improvements in recent years. For starters, more and more schools of higher learning have introduced or improved their online education platforms. And a number of providers have also turned to user ratings (评价). “Star teacher”, for example, has become a popular rating method in some countries. It commonly uses star symbols to show users’ opinions about teachers and their lessons, which helps good teachers stand out from others.
The development of education technology has also made online education become easier to get and more controllable. What a student needs are a computer, an Internet connection and some basic IT skills. Besides, some people say that online education has greatly helped make education easier to get, thus achieving the goal of “education for all”.

【推荐2】During the novel coronavirus outbreak, hospitals all over China have used smart technology to care for patients and make work easier for doctors. The outbreak will help smart healthcare develop faster in China, according to Xinhua.
Robots lend a hand
Robots are being used to fight the virus. For example, medical workers at the Third People's Hospital of Shenzhen are using robots to do routine (常规的) medical tasks.
Developed by Chinese AI company UB Tech, these robots can offer medical advice, deliver (递送)medicine and disinfect (消毒)the patients’ room and other areas. They can also check temperatures.
Liu Yue, head of the hospital's fever outpatient services(发热门诊), said the robots have made work much easier. "It greatly reduces our burden (负担), and it can also prevent us from missing infected patients," Liu said.
Remote (远程的) healthcare services
It can be dangerous for medical workers and patients to come into contact with each other. But with remote medical services, doctors at different hospitals can share photos and videos to come up with the best treatment. China's three biggest telecom companies(电信公司) are providing hospitals across the country with 5G support. This allows them to transfer(传送) large amounts of data (数据) quickly.
For example, on Feb 27, doctors in the cities of Beijing, Shanghai and Guangzhou used 5G technology to treat a seriously ill 67﹣year﹣old patient in Wuhan. By diagnosing (诊断) patients remotely, doctors can protect both themselves and their patients.
AI makes work more efficient
Ask Bob is an AI﹣powered consultation(咨询) platform. Developed by Ping An Smart Healthcare, it can provide users with information about the virus, help people do medical self﹣checks, check their mental health and choose the right face masks.
Ping An Smart Healthcare has also developed AI software that can read CT images and provide correct analyses to doctors. This can speed up the diagnostic process and allow doctors to give faster treatment.

【推荐2】This year, about one hundred teenagers from all over China will spend one year in American homes. They will attend schools and meet teenagers in the U.S., and have a new understanding of America. At the same time, about one hundred American teenagers will come to China to learn Chinese and get a new understanding of China.
A 15-year-old exchange student, Fred, spent last year in China with Li Hua’s family. In turn, Li Hua spent a year in Fred’s home in America.
Fred knew little Chinese when he arrived, but after two months’ study, the language began to come to him. School was completely different from what he had expected — much harder. Students stood up respectfully(尊敬地) when the teacher entered the classroom. They took fourteen subjects instead of six in the United States. There were almost no outside activities.
Family life, too, was different. The father’s word was law, and all activities were around the whole family rather than individuals(个人).
“Back home, you pick up some friends in a car and go out and have a good time. But in China, you walk home and you have to finish your homework first.”
At the same time, in America, Li Hua, a friendly Chinese boy, was also forming his idea. “I suppose I should criticize(批评) American schools,” he says. “It is much too easy by our level. But I have to say that I like it very much. In China we do nothing but study. Here we take part in many outside activities.”

【推荐3】It’s 7 a.m. It’s time to go to school. What? You don’t want to go? Well maybe you don’t have to. Many kids don’t go to school. They stay at home. Someone teaches them at home. Usually, their parents teach them, but sometimes a special teacher teaches them. This is home schooling.
There are many reasons for home schooling. Some children are very sick and cannot go to school. Some students live very far in the country. There aren’t any schools near their homes. Sometimes, parents just don’t like the schools near their homes. Home-schooling sounds easy, but it’s really not. Home-school students have to do the same work as regular(正规的)students. They study the same subjects and have homework. Also, home-school students don’t meet other students in school. Sometimes, finding friends can be hard for them. Not going to school can be harder than you thought.

Sweet idea Honey is produced by bees. But today’s beekeeping business(养蜂产业)is not good for these hard-working insects. Bee farmers may kill them after getting honey because it’s cheaper than feeding the bees through the winter. To save bees, US company MeliBio has found a way to make the world’s first bee-free honey. They used synthetic biology(合成生物学)to create honey directly from plants. This kind of honey tastes just like the real one, and it is healthy, too. |

【推荐3】There is a close relationship between humans and dogs for thousands of years. We love dogs for many reasons, including their loyalty (忠诚的), their sense of fun and how soft they are. Now researchers have found another reason why humans might like dogs: their wagging (摇摆的) tails.
A research team looked at more than 100 studies on tail-wagging. They noted that dogs wag their tails to communicate, but different types of tail-wagging might be sending different messages.
The research team came up with two possible explanations. The first has something with the rhythm (节奏) of tail-wagging. Rhythm is repeated sounds or movements—it’s an important part of music. Humans love music, too. So they chose to make friends with dogs that wagged their tails more. Then this tail-wagging would have been passed down to the dogs’ children.
The second explanation is that humans chose dogs for other reasons, such as tameness (温顺), and dogs with these qualities (特性) happened to wag their tails more. This would make tail-wagging a side effect of domestication (驯养).
More research is needed because no one really understands how or why wagging happens. One of the team, Andrea Ravignani, told the science. org website that there is a lot of work to be done. “We still don’t know exactly which parts of the dog brain control which features (特征) of the tail-wagging,” she said.
