School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, cannot teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So much more is to be learned outside school by the students themselves.

It is always more important to study by oneself than to memorize some facts or a formula (公式). It is actually quite easy to learn a certain fact in history or a formula in maths. But it is very difficult to use a formula in working out a maths problem. Great scientists, such as Einstein, Newton and Galileo didn’t get everything from school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.

Above all, they knew how to use their brains.

【推荐3】I really place many people into two categories when it comes to shopping. The first is people who simply love doing window shopping and do it quite regularly maybe because they are really good at spotting bargains. The other category, which I suppose is obvious that people who simply dislike shopping for anything. They find it very boring, laborious and frustrating and do not particularly like going to their local shopping malls for anything whatsoever. They will probably do anything to try and get away with shopping for gifts and I had the same problem until I discovered something.

The simple discovery was to shop online for everything. This is especially fantastic when you are shopping online for gifts because there are so many websites out there dedicated to supplying all kinds of gifts for every occasion you can think of. The greatest thing is that you can do this from the comfort of your own home without having to leave and sit at a computer with a nice mug of coffee to help.

Researching is always important because you need to make sure whoever you are going to purchase this before is going to like it. You need to make sure of your researched pricing to ensure that you are getting good value for money. Generally, online you will always find things cheaper than buying something in a store in your local shopping mall. The fact that the website does not have many overheads with staffing gives them the opportunity to sell products at a reduced price.

It’s also important that you make sure the website you purchase things from has a good reputation. Check their customer service and also read any feedback that they may have from customers who have already made a purchase.

【推荐1】Japan is starting to experiment with self-driving buses in rural (乡村的) communities, such as the town of Nishikata, where the elderly are living a hard life because of fewer bus and taxi services as the population ages and becomes smaller.

The advance of the self-driving technology is making cities such as Paris and Singapore experiment with such services, which could prove important in Japan, where populations are not only graying, but becoming smaller, in rural areas.

Japan could start the self-driving services for communities that are far from cities by 2020, if the experiments begun this month prove successful.

The government plans to turn highway rest stops into centers from which to drive the elderly to medical and banking services.

“Smaller towns in Japan are graying even faster than cities, and there are just not enough workers to drive buses and taxis,” said Hiroshi Nakajima of mobile gaming software maker DeNA Co.

In the initial (最初的) experiments, the elderly of Nishikata were sent from a service area to some organizations providing healthcare services.

“I worry about not being able to go out when I’m no longer able to drive,” said one test rider, Shizu Yuzawa, adding that she would be open to using such services.

The test also checked the vehicle’s safety in road conditions, and if those crossing its path would react to the warning it gives.

The ride, at a speed of about 10 kilometers per hour, felt comfortable and safe, said test taker Mieko Shimazaki, 71, but her 72-year-old husband, Susumu, said, “Self-driving cars could be useful in the future, but I’d like to see them go faster, at least at 40 kilometers per hour.”

【推荐2】If you’ve visited a museum, you’ve seen it. Maybe you’ve even done it taken a picture of yourself with a piece of art. Perhaps it’s because you love the painting or sculpture, or maybe it was just a famous piece of art and you wanted to share with the world that you’d seen it in person. But the majority of museums ban（禁止） photography at the museum.

The reasons for banning photography differ. Some museums have pieces lent to them that aren’t allowed to be photographed according to the owner’s wishes, like most of the exhibits at The Tate in London. Others are concerned about what camera flashes will do to the art; bright lights can damage certain paints. Some want to preserve a certain atmosphere. Sir John Soane’s Museum,a small museum in London, states that it bans photography to “maintain the unique, magical atmosphere insides”.

For other museums the “no photography” rule is based on observed behavior that seems to fly against the idea of what the museum is for: “Personally, what I’ve noticed is that people spend more time taking pictures than looking at pieces of art,” said Benoit Parayre, the director of communications at the Center Pompidou in Paris. “They take a picture, and don’t even stop in front of the paintings. ”

For most museums. it’s purely practical. “People taking selfies（自拍）are more concerned with getting their shot than paying attention to where their bodies are. some nearly backing into objects,” complained Heidi Rosenau. the Frick’s communication director. What’s worse, in a busy museum, people taking photos with the art causes traffic-flow issues. Sure, some people only take a quick shot, but we all have a friend or two who spends minutes getting the “perfect” photo--now just imagine them in a museum blocking people from seeing famous works of art that they’ve spent time and money to come and see.

A selfie can be fun and harmless, but it can also be rude and get in the way of other people’s experiences.

【推荐3】Some people have glibly（轻率地）called it the "Chinese burger." But roujiamo, a food that has its origins in northern China's Shaanxi Province, is different from what you'd order at Burger King, with a far longer 2,000-year-old history. Roujiamo is a thing of beauty — a soft but chewy bun filled with small pieces of braised（炖）pork.

Most amazingly, some customers might show their respect for the pork in this little bun, which was just bathed in the soup that is older than them. Among a sea of tough competition, Lijiarongxi, a restaurant recognized as the best roujiamo place in town, should owe its success to the soup used to slow-cook its meat, which has been braised on the stove since the founder, Mr. Li, first braised it 27years ago. In fact, most restaurants of good fame have an exclusive heritage recipe（家传秘方）for their soups that often date back to decades ago. The soup in Fanji Roujiamo, one of Xi'an's best-known roujiamo restaurants, is believed to be more than 80 years old!

You might eat the bun quickly in seconds, but like all good things, it should be given time to enjoy. Chefs braise the pork in its decade-old soup for hours and let it sit overnight, making the meat more tender. Such tenderly cooked meat is what lends this dish the nickname "lao han xi" in Xianyang. That's because the best roujiamo meat is so soft that it should melt in your mouth without having to chew it — imagining the elderly customers in question, without a perfect set of teeth.

It's also worth noting that like most types of regional Chinese food, roujiamo varies depending on the city and community. Buns come baked or pan-fried, and for the meat, Muslim communities in Shaanxi often use beef, while people in Ningxia usually choose lamb.

【推荐1】I’m an English teacher working in Russia, and for some reason I really don’t like that classroom topic—Talk About Your Family. Perhaps it’s because everyone studied English from the same book at school. So all the students say, “My family consists of five members: me, my mother, my father, my brother and my dog...”and so on, as if all families are exactly the same.

Let’s get rid of the phrase“my family consists of ...”and look at some more interesting ways to talk about families. English is rich in idioms (习语) to talk about family life. Let’s ignore the black sheep of the family—that’s someone who doesn’t fit in, or causes a family scandal (丑闻). If you’re loyal (忠诚) to your family, you can say blood is thicker than water or keep it in the family. If you share a talent with another family member, you can say it runs in the family. You might have your father’s eyes or your mother’s nose. If you’re like one of your parents, you can say like father, like son or you can be a chip off the old block.

Then there are idioms that have left the family (flown the nest) and gone on to have a life of their own. For example, a Londoner is telling someone how to get a new passport. “Get four pictures taken, pick up a form in the post office, hand it in with your old passport and... Bob’s your uncle.”It means“the problem is solved”. But I’d love to know who the original Bob was, and why he was such a useful uncle to have.

【推荐2】When I met her， I had a lot of anger inside of me. I've lived my whole life in Spanish Harlem， but in my neighborhood， there are shoot﹣ups（枪击）all the time. I know kids who have been shot or beaten up I have friends who ended up in prison. I could have ended up that way， too. but Ms. Clark wouldn't let that happen.

Ms. Clark worked long hours， making sure I did my work. My grades rose. In fact， the scores of our whole class rose. One day， she took our class to see The Phantom of the Opera， and it was the first time some kids had ever been out of Harlem. Before the show， she treated us to dinner at a restaurant and taught us not to talk with our mouths full. We did not want to let her down.

Ms. Clark was selected as Disney's 2015 Teacher of the Year. She said she would draw three names out of a hat； those students would go with her to Los Angeles to get the award. But when the time came to draw names， Ms Clark said， "You're all going. "

On graduation day， there were a lot of tears. We didn't want her class to end. In 2016. she moved to Atlanta， but she always kept in touch. She started giving lectures about education， and wrote a bestselling book based on her classroom rules， The Essential 55. In 2018， Ms Clark took some of us on a trip to South Africa to deliver school supplies and visit orphanages （孤儿院）. It was the most amazing experience of my life.

【推荐3】Every animal species carries unique viruses that have specifically adapted to infecting it. Over time, some of these have jumped to humans — these are known as “zoonotic” viruses.

As the population grows, we move into wild areas, which brings us into more frequent contact with animals we don’t normally have contact with. Thus viruses can jump from animals to humans and they can spread between humans, through close contact with body fluids (体液) like blood or urine.

Because every virus has evolved to target a particular species, it’s rare for a virus to beable to jump to another species. When this does happen, it’s by chance, and it usually requires a large amount of contact with the virus.

Initially, the virus is usually not well-suited to its new host and doesn’t spread easily. Over time, however, it can evolve in the new host to produce variants that are better adapted.

When viruses jump to a new host, a process called zoonosis, they often cause more severe disease. This is because viruses and their initial hosts have evolved together, and the species has time to build up resistance. The new host species, on the other hand, might not have evolved the ability to tackle (应对) the virus. For example, when we come into contact with bats and their viruses, we may develop rabies or Ebola virus disease, while the bats themselves are less affected.

It’s likely that bats are the original source of three recently emerged coronaviruses: SARS-CoV (2003), MERS-CoV (2012) and SARS-CoV-2. All of these jump from bats to humans via an intermediate animal; in the case of SARS-CoV-2, this may have been pangolins (穿山甲), but more research is needed.
