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.

    Mary likes English very much. She works hard. She reads English every morning. She likes speaking English. She often listens to the radio. She watches TV only on Saturday evening. Does she like dancing? No, she doesn't. But she likes drawing and singing. Her parents like her very much. And all the teachers and her friends like her, too.

    I always knew that I depended way too much on my phone, but I didn't know how much. So I decided to do this challenge(挑战) to find out.

     Every morning since I got a smartphone, I've used The Weather Channel App to find out what to wear. On the first morning I had to dress without guidance, but thankfully I was able to guess that the day would be cold and foggy by looking out of my window.

    I couldn't tell what time it was. I haven't worn a watch for more than a year, because my phone showed the time. So I was late for picking up friends who had been on the bus for two hours from Santa Monica to Palos Verdes. I was also late for my part-time job. And even worse, I couldn't call people to tell them that I was running late.

    Getting to places was harder, too. I got lost because I couldn't use the GPS(导航系统) on my phone. My driving, though, got a lot safer because I no longer had my phone in one hand checking directions while driving with the other.

    But the number one trouble was not having my contact list (联络簿). I forgot to write down my friends' and family members' phone numbers before I started the challenge. It was sad to realize that I couldn't remember my brother's and my mom's cellphone numbers. Oh, how I wished to turn on the phone for just a second to look up phone numbers!

    Even with all the problems, however, I found peace not worrying about missing a text message or an email.

    This challenge was a great learning experience. It surprised me how I'd taken no notice of even the simplest things like remembering phone numbers. We all should take some time to think about how we can depend less on our cellphon

Hi, I'm Gina. In February, 2018 my mother had a yard sale. During the sale, she had a conversation with a young girl called Nancy, for they had a common interest in some books she had for sale. They enjoyed their conversation so much that they exchanged their phone numbers. Later they became friends and got together a few times. When my mom moved into her new house, she had a family dinner and invited Nancy and introduced her to my brother. Five months later Nancy married (结婚) my brother.

In 2018, there was another special "yard sale" that I'll never forget. One day, after work from school, I found one of my neighbors had a lot of things out in their front yard with cars and people everywhere. I ran to the yard at once and wanted to find some good cheap things too before everything good was gone. But then I found out it wasn't a yard sale. In fact, policemen were taking the stolen (被偷的) things out of the house. My neighbor was a thief! Luckily, I didn't ask how much the TV was.
