Have you ever asked your relatives or friends if there is Wi-Fi in their houses? Have you ever searched for Wi-Fi when you are at restaurants or hotels? The answers will probably be "Yes". Most of us want Wi-Fi everywhere as if we can't live without it. But we can only use free Wi-Fi in some public places. We still have to spend some money accessing(连接)the Internet at most time. Here comes a piece of good news.

    A rich, powerful organization(组织) in the USA called the Media Development Investment Fund (MDIF) has decided to change the age of online computing (计算) completely by giving free Wi-Fi to every person on Earth. They will send up hundreds of satellites into low Earth orbit(轨道).

    This is because they have made a survey(调查) and found that only 60% of the world's population have been able to get information on the Internet. And this is also because many countries are unable to offer people the necessary infrastructure(基础设施)to access the web.

    We can hope to use free Wi-Fi everywhere in the near future.

    How do we know what's right or wrong in English? Languages such as French and Spanish each has an official(官方的) organization that tells you what's correct. But there is nothing like that in English. So what can we do?

    There is, of course, Standard English. This is the kind of English you read in newspapers or in formal letters. It is also the English you learn at school or in textbooks.

    However, Standard English is not official English. And unbelievably, linguists（语言学家） think Standard English is on the same level as all other types of English such as Cockney English, Yorkshire English, South African English, Australian English, Singaporean English… And according to linguists, there is no such thing as Standard Spoken English.

    English is changing all the time. Every year, new words appear and others disappear. Words change too. For example, for many years, the Latin word “agendum” was the accepted singular form and “agenda” was the plural form. However, these days, very few people use the Latin-sounding“agendum”, with “agenda” being the accepted singular form, and “agendas” the plural.

Newspapers each has their own style when they write certain things. For example，The Guardian puts dates like “21 July 2011”(with the day first, followed by the month and no commas). However, the news agency Reuters writes them like this “July 21, 2011”(with the month first, and a comma(逗号) between the day and the year). Other newspapers have different ways of doing it too. So, as you can see, there's no one “correct” way —there's a variety of ways and each one is acceptable.

    Next time someone tells you that something is wrong, tell them that it isn't wrong, It is just English.

    The People's Bank of China will come out the fifth edition(版本)of the renminbi (RMB) from August 30, 2019. These banknotes(纸币)will have brighter colors and new security features(防伪特征).

    We've been using banknotes for around 1,000 years. Back in the Northern Song Dynasty, Chinese people made the worlds earliest paper money to replace(代替) metal coins. These banknotes were called jiaozi.

    Paper money is cheaper to make and easier to carry. These advantages made it more popular than other forms of money. But now, in the digital (数码的)age, paper money seems to be disappearing for the same reason.

    China seems to be heading towards becoming a cashless(不用现金的) society. From supermarkets to street stores, people pay by using the We Chat Wallet and Alipay apps on their mobile phones. Sweden is even closer to a future without paper money. Many Swedish banks no longer even have cash on hand.

    But there are worries about creating cashless societies. Some say it is unfair to the poor and people without much education. It's not easy for them to open bank accounts( 账户)or deal with mobile phones. And if all of your money is" digital, it may not be safe enough.

    Is paper money going away? Although paper money is used less than electronic payment (电子支付) in some countries, it won' t disappear at once in most parts of the world.

    Where did you go this summer vacation? Perhaps you have visited some top universities. If so, you are not alone.

    This summer vacation, thousands of people from across the country traveled to famous universities like Tsinghua University, Peking University and Fudan University. For example, about 6,000 visitors visited Tsinghua University every day on vacation. Most of them were junior high school students and senior high school students with their parents.  With more and more people coming to these universities, it usually took many hours to enter them.

    "Tsinghua University opens to the visitors at 8:30 am." a guard (保安) told China Daily. "However, many people start to wait in line at3 to 4 am. If people come at 6 o'clock, it may be too late and they can only enter in the afternoon.

    "University tourism" is popular because of the long histories and special cultures of these famous universities. Also, many parents hope their children can learn something more from the trip and study harder after that.

    "I brought my son here as soon as I finished my job," Mrs. Zhang, a mother of a 14-year-old boy, told China Daily. "And I hope my son will go into a top university in the future."
