　　Data Map: On the third day of the first month in year of the loong, adults and children played "the games we played together in those years" at the Spring Festival Temple Fair in year of the loong, Xintiandi, Wuhan, playing marbles, kicking shuttlecock and rolling hoops. China News Agency issued ZhangChang photo

　　BEIJING, Beijing, 12 Jan (Shangguan Yun) "Drop, drop, drop the handkerchief, and gently put it behind the child. Don’t tell him, hurry up and catch him, hurry up and catch him … …” I believe that this children’s song has a place in many people’s memories. Twenty years back, in that era when the material conditions were not as rich as now, it was not one popular video game after another that occupied many people’s childhood memories, but a series of simple but memorable entertainment activities such as "finding friends", rubber-jumping and throwing sandbags.

　　For example, "turning the rope" is usually the cooperation of two people: a piece of thin rope is tied into a rope loop, put on two wrists or "put on the palm", and then woven into a pattern with fingers; The other deftly picked up the string with his fingers, connected the loop and turned it into another pattern. In this way, according to a certain routine, turn all the way down until it is turned back to its original state.

　　There are quite a lot of rope-twisting routines. Two people can play and one person can play. It is said that there are more than 2,000 patterns that can be summarized so far. However, there are only four or five styles that can be turned out by two partners: bridge, noodles … … Wang Xu, the author of the popular book At that time, recorded this kind of game in detail. He said that he could vaguely remember that the fishing net and noodles followed, from the crossed fishing net in one hand to two parallel noodles in the other’s hand, which was very vivid. "And ‘ Take a bath ’ In fact, it is an empty circle — — It turned into a bath basin, and it was soaked in soup, so I had to start all over again. "

　　"It’s not just rope climbing. When we were young, there were all kinds of fun games such as hopscotch, throwing sandbags and origami." After 90, Huang Xiaofei still remembers that girls like to play bungee jumping together in primary school. Basically, four or six people play together and are divided into two groups. One group puts on the rubber band and the other group jumps. According to the rules of the game, the jumping party loses and then replaces each other. "If you hook the rubber band, you lose. This game especially tests dexterity, sometimes ‘ Addiction ’ Come up, two people can also play, and the other end is tied to the tree. "

　　Besides bungee jumping, Li Jing, a post-90s girl, liked and often played the game of "playing glass ball" when she was a child. "Strictly speaking, boys played glass ball more than girls, so I was quite different at that time".

　　How to play "playing glass ball" Li Jing said, we should first dig a hole of moderate size on the ground, which should not be too wide or too narrow. Most of them are stuck with the diameter of the glass ball, which makes it a little difficult. "There are not too many people, and there are several different types of play. The simple thing is to draw a line away from the dug hole and bounce the glass ball in outside the line to win, which is a bit like golf; Later, it was developed to be able to bounce someone else’s glass ball into a small hole, which also counted as winning the other party. "

　　"At that time, in order to play, I collected a lot of glass balls and took money to buy them in a small store. I remember that there were one dime and one dime. Unfortunately, the technology was not pure enough, and it was not long before I was won by other little boys." Speaking of the past, Li Jing couldn’t stop smiling. "There are many types of glass balls, some of which will be embedded with patterns, which are particularly beautiful. Then I won’t be willing to take them out for the competition, and I will quietly collect them."

　　In fact, in addition to jumping rubber bands, turning ropes and playing glass balls, there are many fond memories of games in childhood, such as jumping houses, throwing sandbags, and a group of people competing to make hand-folded roses and paper crane … … Huang Xiaofei especially misses those games when she was a child. In her eyes, they are not just games, but also memories intertwined by many people of different ages. "We miss not only those games that look simple now, but a feeling and miss the quiet time in the past."

　　Wang Xu has a similar feeling. He said that the original choice to record these games was to express a feeling of nostalgia for childhood. "The most emotional games are not necessarily the most fun games, but games like soap bubbles, rope turning and handkerchief throwing that reflect childhood innocence and warm friendship between children."

　　"Most of the children don’t play these games now. If you only look at it from the perspective of playing, it may be far less interesting than what they are playing now. " Wang Xu does not deny that some of the previous games have become "outdated", but he feels that the individuality and creativity, closeness to nature and the face-to-face interaction between children in these games have all been lost. "This is a pity for the children." (Some interviewees in this article are pseudonyms) (End)

　　Everyone can travel without cash now, but many people dare not take their bank cards, for fear that they will not be able to get money from the ATM in case they need cash. In fact, with the continuous innovation of bank deposit and withdrawal methods, it is nothing new to deposit and withdraw cash without a card. Beijing Youth Daily reporter recently visited a number of banks and experienced a variety of convenient services that can be enjoyed without a bank card.

　　Brush face to withdraw money: there is a limit.

　　The latest way to withdraw cash without a card is to push the face to withdraw money. Stand in front of the ATM, let the camera take a picture, and then enter a few simple messages, and the money can be spit out from the ATM. A plot that sounds like science fiction has now become a reality. At present, some ATMs of China Merchants Bank, Agricultural Bank of China, China Construction Bank and other banks have the function of withdrawing money by brushing their faces.

　　In October 2015, China Merchants Bank took the lead in announcing the launch of "ATM face-brushing withdrawal" business in China. Now there are hundreds of ATMs of China Merchants Bank providing this service in Beijing.

　　How to use this function? On the homepage of ATM screen of China Merchants Bank, there is a function bar of "brush face to withdraw money". After clicking it, the customer enters the face recognition image screen, and the customer must face the ATM camera to expose the whole face, and can’t block it and shake it frequently. After the system automatically captures the customer’s head, the page will prompt the cardholder to enter the mobile phone number reserved in China Merchants Bank, and the system will automatically compare it. After matching, the ATM will display the card number information under the customer’s name, the customer will select the card number for withdrawal, and then enter the withdrawal amount and password, and the cash will be spit out from the machine. If the system does not match, it will prompt that the personal information cannot be matched and the transaction is cancelled. The whole process is very convenient without inserting a card to get it.

　　ABC’s face-brushing withdrawal process is basically similar to that of China Merchants Bank, except that in the process of identity verification, ABC can choose to enter ID number or mobile phone number. According to the experience of netizens, the withdrawal can be completed in less than one minute, which is similar to the withdrawal with a card.

　　However, in terms of functional authority, ABC’s face-brushing withdrawal function does not need to be specially opened, while China Merchants Bank needs cardholders to specially open this function on mobile banking. Considering that face recognition technology is an innovative attempt in the field of withdrawal, in order to reduce security risks, there is a limit on the current "face-brushing withdrawal". China Merchants Bank’s cumulative withdrawal limit for a single card on the same day is 3,000 yuan; Agricultural Bank of China does not exceed 3,000 yuan per day for a single transaction, 10,000 yuan per day in total, and no more than 5 times per day.

　　Scan the code to withdraw money: use the bank APP

　　When people pay the bill, they are used to taking out their mobile phones to scan the code. In fact, they can also withdraw money by scanning the code at ATM.

　　In May last year, ICBC launched a new service of mobile banking to withdraw cash by scanning code. Customers don’t need to use the physical medium of bank cards, just open the "scan" function in ICBC’s mobile banking client, scan the QR code displayed on the ATM screen, enter the withdrawal amount and use ICBC e-payment to verify it successfully, and then click the "Withdraw" button on the ATM to complete the whole withdrawal process. If the customer has enabled the one-click payment function of mobile banking, it is more convenient to complete the payment safely by inputting the preset static payment password in the mobile banking client without inputting the mobile phone number, account, verification code and other information in the process of code scanning cash withdrawal.

　　On September 15th this year, the ATM of Bank of China added the function of mobile phone scanning QR code to withdraw cash. A few days ago, the reporter came to a 24-hour self-service bank in a branch of Bank of China for a field experience. To withdraw money by scanning code, you need to download the mobile banking APP of Bank of China on your mobile phone and bind it with a bank card, without opening other permissions. Then, click "scan code to withdraw money" on the ATM screen of Bank of China, scan the QR code on the ATM with the "scan" function of mobile banking, then enter the withdrawal amount, confirm the withdrawal account and enter the withdrawal password, and you can successfully withdraw the required cash. The whole process takes only a few minutes.

　　According to reports, Bank of China’s ATM scanning code withdrawal adopts double insurance of mobile banking APP verification and ATM encryption verification. When withdrawing money, you need to log in to mobile banking through your fingerprint, and enter the withdrawal password at ATM, which effectively ensures the security of customer accounts and funds. At present, the ATM scanning code withdrawal of China Bank is completely free, and the daily withdrawal limit is 5,000 yuan.

　　Pay withdrawal by mobile phone: to verify fingerprints

　　After Apple Pay entered the China market, it captured the hearts of many fruit fans by paying the bill with one stroke. In fact, cardholders can also withdraw money without a card through Apple Pay at ATM. Samsung Pay and Huawei Pay can do the same.

　　As long as the cardholder’s mobile phone and ATM both support related functions, the cardholder can successfully withdraw cash from the ATM by swiping the mobile phone and checking the fingerprint "Pay". At present, some ATMs of CCB, China Merchants Bank and China Everbright Bank have supported cash withdrawal through "Pay".

　　Take Everbright Bank as an example, it only takes five easy steps for cardholders to withdraw money through Apple Pay at Everbright ATM. First, choose the contactless IC card withdrawal service at ATM, enter the withdrawal amount, then put the mobile phone near the sensing area, verify the fingerprint through Touch ID, enter the withdrawal password, and verify the fingerprint through Touch ID again, and the withdrawal can be successful.

　　Withdrawal by appointment: the limit of each bank is different.

　　Before face-brushing withdrawal, code-scanning withdrawal and mobile phone Pay withdrawal, more banks carry out card-free withdrawal business through appointments in mobile phone banking, online banking, telephone banking and other channels. It is understood that there are differences in specific details among banks in handling cash withdrawals without cards, but the handling steps basically include two links: online reservation withdrawal and offline cash withdrawals without cards.

　　When making an appointment, banks generally require customers to choose the account and withdrawal amount for making an appointment, but other agreed information varies slightly from bank to bank. For example, CCB will ask for an appointment for the withdrawal period and area, and the cardholder will withdraw money from the ATM with the special withdrawal ID and withdrawal password received by SMS. ICBC needs to set a 6-digit reservation code, and the reservation is valid only on the same day, and it is stipulated that a debit card registered with mobile banking can be withdrawn without a card. The maximum amount of a card-free withdrawal by ABC is 3,000 yuan, and the reservation is valid for 24 hours. You can directly use the "card-free reservation withdrawal" function at ATM, and you can withdraw money by entering your mobile phone number and withdrawal password, without other reservation codes or verification codes.

　　In terms of cash withdrawal amount, most banks can make a cumulative appointment of 20,000 yuan per day for cash withdrawal without a card, but there are differences in the single cash withdrawal limit and the number of cash withdrawals per day. In terms of a single amount, some banks do not exceed 2500 yuan at most, and some banks can reach 3000 yuan. CCB also stipulates that the cumulative number of days for mobile banking to apply for special withdrawals should not exceed 5,000 yuan.

　　No card deposit: you need to remember the card number.

　　You can withdraw money without a card and deposit without a card. Yesterday, Beijing Youth Daily reporter saw the function bars of "no card deposit", "no passbook deposit" and "no card passbook deposit" on the deposit and withdrawal machines of most banks such as ICBC, CCB and ABC.

　　After clicking Enter, you need to completely enter the card number or passbook number twice. After checking the account and the owner’s name, the deposit slot at the bottom of the electronic screen will open, and the customer will put the banknotes with face value of 100 yuan into the deposit slot, and the machine will start counting. After the counting is completed, the unqualified banknotes will be required to be retrieved, and the number and total amount of qualified banknotes will be displayed on the screen. After the customer confirms, the information such as account, account name and deposit amount will be displayed again. After final confirmation, the transaction is completed, and you can choose to print the receipt.

　　It is worth noting that only 100 yuan banknotes can be deposited, with a maximum of 100 banknotes at a time. The deposit account can be your own or someone else’s.

　　Safety tips

　　The security of withdrawing money without card is strong, so we need to be vigilant.

　　Bankers remind that although it is simple and convenient to withdraw money without a card, cardholders should always pay attention to protecting their own funds. In operation, it should be noted that after users make an appointment to withdraw money on platforms such as mobile banking, they will receive information such as "special withdrawal number, set special withdrawal password and withdrawal amount" issued by the bank. For such short messages, users need to take good care of them and avoid leaking them (for example, forwarding bank notification short messages to others) to ensure the safety of funds.

　　In addition, users need to be especially alert to criminals using "cash withdrawal without card" to commit fraud, especially not to send the verification code received by the mobile phone to others in any form. Previously, there have been cases in which criminals used the bank’s card-free appointment withdrawal business to commit fraud.

In March, 1928, American explorer Joseph Charles Francis Rock, with the help of King Muli, set foot on a road through the mysterious mountain and went deep into the local place called Gongga Risong Gongbu, which is now the Aden area of Daocheng.

Locke was impressed by the magnificent scenery here, and then published relevant articles and photos taken along the way in National Geographic magazine, which caused a great sensation in the west and showed this "pure land on the blue planet" to the world for the first time. At the beginning, the expedition team crossed the route from Muli to Gongga Ridge, which was later called "Locke Line".

The "Locke Line" has made countless adventure enthusiasts flock to it. Nearly a century later, Richard, an international student from France, led by the local explorer Lao Yin, re-took this world-class hiking route on the plateau and started an adventure through time and space to find the true meaning of Shangri-La.

Inspiration for China is an international communication video column created by Sichuan Daily Newspaper Group. The column is located in the "Z generation" group at home and abroad, and it explores, discovers, excavates and disseminates China business cards such as ancient Shu culture, tourism geography, Sichuan cuisine, animation online games, traditional Chinese medicine, modern art and sci-fi legends.

In the English review from the entrance examination to the undergraduate level, the examination syllabus not only shows the content of the examination, but also explains the types of the examination. Candidates can choose their own suitable preparation materials according to the examination syllabus, and gradually learn with the materials to improve their learning ability step by step.

In the investigation of English subjects, the original title rarely appears, but the deformation of the original title often appears. Therefore, after preparing for the exam for a period of time and mastering the basic examination knowledge, candidates should still do the questions carefully, check and fill in the gaps from the questions, find their own knowledge weaknesses, and then consolidate them again.

Adult college entrance examination is a major that decides whether candidates are admitted or not according to the principle of "selecting the best candidates from high scores to low scores".

Undergraduate: According to the principle of filing, the Provincial Education Examinations Institute files from high scores to low scores according to candidates’ wishes. Colleges and universities determine whether candidates are admitted or not and the majors they record, and return the electronic files of those who are not admitted.

Specialty: According to the principle of "giving priority to scores and following volunteers" in parallel volunteer, the Provincial Education Examinations Institute puts the candidates’ files on the provincial control line according to the enrollment plan of colleges and universities. Colleges and universities determine whether to admit candidates and their majors within the enrollment plan limit, and return the electronic files of those who have not been admitted.

This year’s admission score line needs to wait until the exam is finished, but the annual admission score line does not fluctuate greatly. Students can refer to last year’s admission score line first. You need to take four exams for starting high school, three exams for starting high school, and three exams for starting high school, each with a perfect score of 150, with a total score of 450.

The above is related to the adult college entrance examination. Candidates can use it as a reference, which is subject to the official announcement!

"equipment optimization"

How can sports be such a professional thing without equipment? Recommended by elite runners and carefully selected by the government, the quality is guaranteed;

　　Can you imagine a world without the sun? Astronomers’ research shows that if there is no sun, the average surface temperature of the earth will drop to below-17.78 degrees Celsius in a week, and it will drop to-73.33 degrees Celsius in a year. Most plants will die in a few weeks, and then most life will disappear because of the disappearance of the sun, and everything will be dead.

　　Now we know how important the sun is to us! However, something unfortunate happened. Recently, foreign scientists’ research on the metal abundance of the sun shows that we may overestimate the life of the sun by one billion years, and the sun may die one billion years earlier than we expected.

　　Elemental abundance controls the sun’s life gate

　　It is understood that scientists have previously deduced that the life of the sun is about 10 billion years based on the standard solar model that ignores the rotation effect, which is a theoretical value simulated by the stellar evolution program, not a real value. And this value only refers to the central hydrogen combustion life in the theory of star evolution.

　　"This is not to say that the sun really can only exist for 10 billion years. The accurate statement should be called the main sequence life of the solar model. In theory, the sun will become a red giant in about 10 billion years, but it still exists and will emit more sunlight. " Associate Professor Yang Wuming from the Astronomy Department of Beijing Normal University told the Science and Technology Daily reporter.

　　He said that there are many preconditions to get the theoretical value of 10 billion years, and it is necessary to assume the initial element abundance of the sun and the physical process inside the sun. The life of the solar model is different with different initial element abundances. Because it is impossible to really get the initial element abundance of the sun and determine its internal physical processes, the life of the sun and even other stars cannot be accurately estimated.

　　Twenty years ago, astronomers’ direct and indirect measurements of the sun showed that the metal abundance of the sun was around 1.8%; However, the latest solar spectrum measurement shows that the metal abundance of the sun is only 1.3%, which is far lower than the previous measurement results, and correspondingly, the life of the sun will be reduced by 1 billion years.

　　The so-called solar metal abundance is the general term for the abundance of solar elements except hydrogen and helium. This metal is different from what we usually call metals. Because the contents of hydrogen and helium in the sun account for the vast majority, astronomers call all the heavier elements in the sun "metals". Although the content of these metals is small, it affects the fate of the sun.

　　Because the electrons of metal elements easily absorb photons, which hinders radiation, the higher the metal abundance of the sun or star, the higher the opacity. The opacity of the sun or star is closely related to its life, temperature, brightness and other properties. Sani Vaniotch, a physicist who studies solar metal abundance at Stockholm University in Sweden, said that a very small amount of metal is enough to completely change the behavior of a star, and metal abundance can basically tell you how the star will die.

　　Influence of atmospheric model on solar lifetime estimation

　　The solar spectral measurement used in the latest research usually means that astronomers get the spectral lines of all measurable elements such as hydrogen, carbon, nitrogen, oxygen and iron through solar spectral analysis, and then compare them with the spectral lines given by the solar atmospheric model. When the two are consistent, the abundance of elements such as hydrogen, carbon, nitrogen, oxygen and iron used in the atmospheric model is considered as the element abundance of the solar photosphere. "However, this method cannot obtain the relative abundance of inert gases such as helium, neon and argon. The abundance of helium on the surface of the sun can only be inferred by helioseismology. " Yang Wuming said.

　　After the latest measurement results come out, many people are wondering: Why is there such a big difference between the solar metal abundance measured before and after?

　　In this regard, Yang Wuming explained that the old solar metal abundance was derived from the one-dimensional atmospheric model of local thermal balance combined with the observed spectral lines; The new solar metal abundance is derived from the three-dimensional atmospheric model of non-local thermal balance combined with the observed spectral lines. The old one-dimensional atmospheric model is considered to ignore many physical factors. Some scientists think that the new atmospheric model is closer to the real situation, and it is the improvement of the atmospheric model and the update of the transition probability data of atoms and molecules that cause the difference in the abundance of old and new metal elements.

　　In the evolution of stars, if other conditions remain unchanged, the decrease of metal abundance will lead to the energy generated by the central nuclear reaction radiating outward more easily. However, the energy tends to radiate outward, which will cause the star to contract more easily and increase the density and temperature of the center of the star. More importantly, the increase of density and temperature will accelerate the hydrogen combustion rate, which will lead to the shortening of the total time of central hydrogen combustion, that is, the main sequence life of the solar model will be shortened. However, if other conditions change, such as the increase of hydrogen abundance or the influence of the sun’s rotation on its evolution, then the aforementioned life reduction does not exist.

　　So, how to verify which method is more correct in the future?

　　In Yang Wuming’s view, the answer to this question lies in which metal abundance measurement is more accurate and whether the helioseismology inversion result is reliable. Only by giving the correct abundance of solar elements can we determine how long the life of the sun is. If we can give a new solar model of gold abundance consistent with the helioseismology inversion results, all related problems will be solved.

　　Life geometry is related to the theory of stellar evolution.

　　Chen Pengfei, a professor at the School of Astronomy and Space Science, Nanjing University, said that he was inclined to think that the initial life span of the sun was correct, and the life span of the sun would not be reduced by one billion years. "For several reasons, I prefer to think that the original model is correct: first, the measurement results of metal abundance in the solar wind by satellites support 1.8%; Secondly, the density of photosphere on the surface of the sun is high enough, so it is reasonable to adopt the approximation of local heat balance model in the past; Thirdly, the new model takes into account the inhomogeneity of the solar atmosphere, which is indeed an improvement, but it also ignores other factors, such as the influence of magnetic field; Fourth, to take a step back, even if the results of the new model are correct, because the distribution of metal abundance may be uneven, the metal abundance on the surface of the sun may be different from that inside. " Chen Pengfei said.

　　At the same time, Yang Wuming also agrees that the initial solar life is correct. He said that the life of the sun has not been overestimated by 1 billion years, and that the life of the sun is overestimated because only the reduction of metal abundance is considered. When the influence of hydrogen abundance increase and rotation on the evolution of the sun is considered, the life of the sun will not be reduced.

　　However, the astrophysicist Martin asp Lund of the Australian National University insists that the 1.3% solar metal abundance is correct. He said that all aspects of astronomy will be affected, and an accurate understanding of the evolution of stars has laid the foundation for almost everything.

　　So, if astronomers do overestimate the life of the sun by one billion years, what theories need to be revised?

　　In Yang Wuming’s view, if the life of the sun is really overestimated by 1 billion years, it shows that the theory of stellar evolution established by astronomers before is not complete, so they need to re-examine the theory and model of stellar evolution established before. For example, the standard theory of star evolution ignores the influence of star rotation, but in fact all stars are rotating. We have reached the time when we need to seriously consider the influence of rotation on the evolution of stars. Astronomical research on star clusters and galaxies depends on the theory of stellar evolution to a certain extent. If the theory of stellar evolution is wrong, the previous understanding of star clusters and galaxies needs to be adjusted.
