1 . On Friday afternoon when I picked Gabriel up from school, he came running towards me smiling widely. Straight away I noticed a gap on the bottom row of his teeth. I felt my heart stop for a moment. At first I thought perhaps he had had some accident, such as falling down the stairs. Gabriel wasn't old enough to lose teeth, was he?!
Before I managed to ask him, he shouted "Mummy! Mummy! I've lost a tooth!” To my amazement, Gabriel appeared to be happy! ”Wow! When did that happen?" I asked. He thought for a few seconds and told me that he wasn't sure. He remembered eating a cake at lunchtime, and later when he checked in the mirror, his tooth was gone! No pain, no stressing and no worries!
I admit I did feel a little emotional. We focused the early years on his teeth growing, but now Gabriel would lose all those baby teeth and get adult ones! I told Gabriel to write to the tooth fairy （仙子）,who would certainly visit, locate the tooth and leave a coin. Surely enough, a shiny coin was under his pillow （枕头）on Saturday. When Gabriel broke the news to Daddy, we laughed about the amount of cash kids make out of their teeth—a child usually has twenty teeth. A nice profit!
I'm proud of Gabriel. He wasn't frightened or confused, although the missing tooth may be in his stomach, which he thought was quite funny! Later I got some knowledge about which teeth are likely to go at specific ages. Of course, the ages aren't quite exact, but at least I know where we're heading.

2 . In the past five years, about 2.8 billion of school textbooks were sold per year, with total spending of 20 billion yuan ($3 billion), news magazine Outlook Weekly reported, citing data released recently by the National Press and Publication Administration.
If these textbooks are reused for one year, the costs saved can be used to help build around 40,000 Hope Schools in impoverished regions.
The figures show that in 2018, the number of retailed textbooks for primary and secondary schools was 2.93 billion copies, totaling 25.99 billion yuan. If all of them are reused, a total of over 20 billion yuan will be saved per year.
Zhao Dehua, in charge of a company recycling resources, said many college graduates sell the textbooks they have accumulated over the years at an average price of 1 yuan per kilogram. As these textbooks are mostly used to produce recycled paper, the cost is even higher than that of raw paper as the processing procedure of recycled paper is complicated.
At present, free textbooks related to music, art and P.E for the nine-year compulsory education have been reused, but account for less than a fraction of the total number of textbooks. Because of the supply chain obstruction, which increases the costs to match supply with demand, the lack of sound platform and service supporting system for the second-hand textbook trade, most of the textbooks used for compulsory education and higher education end up as waste.
“Every year, second-hand booksellers collect textbooks at a price of about 4,000 yuan a ton, which is more than twice the price of ordinary waste paper, but the number of people who come to collect second-hand books is still few,” Zhao Dehua said.
Besides, the incomplete policies and regulations might bring second-hand book sales platforms and sellers to legal risks.
“Establishing the system of textbook recycling can not only save resources, but also help to cultivate students’ consciousness and sense of responsibility,” said Zhu Pin, deputy head of a school of nine-year compulsory education in Jiangxi province. The school has set up a system for reusing the textbooks and the books are disinfected every week.

3 . Bamboo is one of the nature's most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains (平原)．
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables (绳索) that hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong.
In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money，and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills (钻) can help to make the poor thirsty fields to be watered.

4 . Many students study with little thought about what comes after a period of study. But what you do after study could have an effect on how well you learn and remember new information. Today on Education Tips, we will explore two no-cost ways that can help you improve your learning: wakeful rest and sleep.
When many students finish study, they often go straight to other activities such as looking at their phones or computers, playing video games or watching TV. But researches suggest that resting after you study may help you remember what you have studied. By reducing your activity after a study period, your brain gets a chance to rest. Resting is difficult when you have too much stimulation from electronic devices, games, lights and so on. While this might sound unusual to you, many studies have explored the benefits of what is called “wakeful rest”.
A 2019 study found that both young and older adults were able to better remember or recollect information from passages after doing wakeful rest. The findings appeared in Neuroscience Letters. This study involved 45 younger people and 40 elderly adults. “Wakeful rest led to higher overall recollection in both age groups,” the researchers noted. If you want to give it a try, here are a few simple things to do. Rest quietly for five to ten minutes. Do not look at your phone, read stories or play games.
In addition to wakeful rest, sleep is also important for learning. The Division of Sleep Medicine at Harvard Medical School notes that sleep helps people to learn in two ways. A report on the school's website explains that “a person who doesn't have enough sleep cannot focus attention and therefore cannot learn well.” It also says, “Sleep itself has a role in improving memory, which is important for learning new information.”

5 . After 7 long years since the cute cat named Chebon went missing, there was little hope that it could be found. Robert probably already came to peace with the thought that he would never see his little friend again until he received a life-changing call. Clearly, a kind stranger reached out to tell him that his beloved cat was safe and sound and couldn’t wait to see him again!
The cat went missing years ago, right before Robert was planning on moving from California to Ohio. The sad owner decided to give up his plans and stayed in California for the whole year looking for his missing friend, but in vain.“I remember at one point I was praying and I said, ‘God, I’ll do anything, just bring my Chebon back…’”, Robert said in a video posted on the Ventura County Animal Services. The cat seemed to have disappeared forever and Robert had no other choice than to move on.
Then 7 years later, a woman noticed a cat that looked ill, so she decided to catch the animal and take him to the vet (兽医). Luckily, the cat she found had a microchip (微型芯片), and in an instant, they knew who the owner of the 19-year-old cat was. That’s when Robert received a call saying that his cat was alive.
“I was afraid there was some kind of mistake,” Robert said in the reunion video. The man decided to ride on a plane and fly all the way from Los Angeles to see his old friend. After finally seeing the cat, Robert immediately recognized his cat and burst into tears. After all these years, the two friends were back together. The touching moment was recorded by the animal shelter and was quickly spread on the Internet, leaving so many people in tears.

6 . The world has many beautiful sounds. we can hear the songs of birds and laugh of people. We can listen to cool music and news reports. And all this is due to(归功于) our ears! They bring us a world of sounds.
But some people can’t hear any sound at all. Some are born deaf. Others can hear well in their childhood, but too many loud sounds hurt their ears later on.
In China, 6 children out of 1000 have hearing problems when they are born. They can not hear ordinary sounds clearly. Children who have hearing problems usually also have learning problems at school.
A lot of things can cause hearing problems. For example, too much earwax is not good for our hearing and noise louder than 85 decibels(分贝) can hurt our ears and make us lose our hearing for a short time or even forever.
Hearing is a problem for all of us. So we should do our best to give our ears special care. Don't forget the following:
Try to stay away from places with too much noise. If you have to go, wear earplugs(耳塞). A pair of earplugs can cut the noise by 30 decibels. When swimming, remember to put earplugs into your ears to stop water from getting in. Never put anything sharp into your ears. If you think you have too much earwax, ask your parents to help you clean it out.
Keep these things in mind! Then you won’t ask “WHAT?” when you are older.

7 . The biggest and the smallest of the world’s animals are most at risk of dying out, according to a new analysis, with vertebrates (脊椎动物) in the so-called “Goldilocks zone”—not too big and not too small—winning out. Action is needed to protect animals at both ends of the scale, they say. The research adds to evidence that animals are dying out on such a scale that a sixth extinction is considered under way.
One clue is body size. Research on birds and mammals has shown that those with larger bodies are more likely to go extinct. Yet, when the researchers made a database of thousands of birds, mammals, fish, amphibians (两栖动物) and reptiles (爬行动物) at risk of extinction, they found disproportionate (不成比例的) losses at the large and small ends of the scale.
“Surprisingly, we found that not only the largest of all vertebrate animal species are most threatened, but the very tiniest ones are also highly threatened with extinction,” Prof. Ripple told BBC News.
Large animals, such as elephants, rhinos (犀牛) and lions have long been the target of protection efforts. However, fish, birds, reptiles and amphibians that are the giants of their kind, such as the whale shark, Somali ostrich (鸵鸟) and the Chinese giant salamander (蝾螈), tend to be overlooked. Meanwhile, small species at risk--such as frogs and shrews (鼩鼱)--receive very little attention.
“I think, for the smallest species, first of all we need to bring higher awareness to them, because the larger ones get a lot of attention, but the smaller ones get very little,” said Prof. Ripple.
In the study, vertebrates with the smallest and the largest bodies were found to be most at risk of disappearing, whether they were on land or living in oceans, streams or rivers.
Heavyweights are threatened mainly by hunting, while featherweights are losing out to pollution and cutting down forests. “Ultimately, reducing global consumption of wild meat is a key step to reduce negative impacts of hunting, fishing, and trapping on the world’s vertebrates,” they write in Proceedings of the National Academy of Sciences.

8 . A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed (消耗) at least an ounce (盎司) of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But long before researchers have noticed that the incidence (发生率) of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption (消费) averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.
At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol (胆固醇) levels.

9 . Brownie and Spotty were neighbor dogs who met every day to play together. Like pairs of dogs you can find in any neighborhood, these two loved each other and played together so often that they had worn a path through the grass of the field between their houses.
One evening, Brownie’s family noticed that Brownie hadn’t returned home. They went looking for him with no success. Brownie didn’t show up the next day, and although they made their efforts to find him, by the next week he was still missing.
Curiously, Spotty showed up at Brownie’s house alone, barking and jumping. Busy with their own lives, they paid no attention to the nervous little neighbor dog.
Finally, one morning Spotty refused to take “no” for an answer. Ted, Brownie’s owner, was continuously disturbed by the angry, determined little dog. Spotty followed Ted around, barking all the time, then darting toward a nearby empty lot (an area of land) and back, as if to say, “Follow me! It’s urgent (紧急的)!”
Eventually, Ted followed Spotty across the empty lot as Spotty stopped to race back and barked encouragingly. The little dog led the man to a deserted spot. There Ted found his beloved Brownie alive, one of his legs stuck in a steel trap. Frightened, Ted now wished he had followed Spotty earlier.
Then Ted noticed something. Spotty had done something else besides leading Brownie’s human owner to his trapped friend. In a circle around the injured dog, Ted found some food remains of every meal. Brownie had been fed that week! Spotty had been visiting Brownie regularly, in the hope of keeping his friend alive. Spotty had actually stayed with Brownie to protect him from hunger and other dangers, and keep his spirits up.
Brownie’s leg was carefully treated and he soon got well again. For many years thereafter the two families watched the faithful friends running after each other down that well-worn path between their houses.

| A．it was Spotty’s timely help that saved Brownie |
| B．it’s not right to hunt animals in any neighborhood |
| C．Ted has to take better care of his beloved dog later on |
| D．humans and animals depend on each other for comfort |
10 . British chemist David Evans has become an overnight celebrity on Chinese social media. His chemistry experiments have attracted over 2 million followers in just a few months. Evans is a chemistry professor at the Beijing University of Chemical Technology. The 60-year-old always wears a white lab coat, a pair of safety goggles(护目镜），and smiles often.Some web users say he looks just like the "grandpa of KFC".
Evans has posted videos of various experiments. His most popular experiments have attracted millions of hits on video-sharing apps. Excited children's cheers and shouts can be heard in his videos. “I hope my experiments can arouse people's interest in science,” he says.
Evans has been interested in China since childhood.In the early 1970s, before the reform and opening-up,he viewed it as a “country full of mysteries". He first visited the Chinese mainland in 1987 to attend a chemistry conference in Nanjing,Jiangsu Province. He quit his job in the United Kingdom and moved to Beijing in 1996. Many of his friends thought he was crazy. But Evans says they just saw China's challenges but not its potential.
Since 2011, Evans has turned to the Internet to popularize science. He learned short-video apps are also popular in small cities and rural areas. And he realized this enables him to reach more students, who lack opportunities to perform fun experiments. But even a one-minute video requires a considerable amount of work. Still, he thinks it's worth it to fulfill his responsibility to popularize science.
His experiments always fill schools' lecture halls with laughter. Some viewers call him "a Harry Potter-like magician”, but he disagrees. “A magician never tells the secrets behind his tricks, but a scientist always gives an explanation.” He sees himself as a teacher. He performs experiments to spread knowledge, inspire thinking, remove misunderstandings and show that science can create change. Evans says he looks forward to more "chemical reactions" with China.
