A language expert says using a full stop to end sentences in text messages can look rude. A full stop is used in British English; in American English, this punctuation mark is called a period. Linguist Gretchen McCulloch says more and more people think ending messages with a full stop is rude. She said this view is most common in younger people who use instant messaging apps like Twitter and Facebook Messenger. Ms McCulloch said people prefer to send a completely new message instead of ending a sentence with a full stop. She said: "If you're a young person and you're sending a message to someone, the default way to break up your thoughts is to send each thought as a new message."

一位语言专家表示，在短信中使用句号来结束句子看起来很粗鲁。英式英语中使用句号;在美式英语中，这个标点符号叫做句号。语言学家Gretchen McCulloch说，越来越多的人认为以句号结尾是粗鲁的。她说，这种观点在使用Twitter和Facebook Messenger等即时通讯应用程序的年轻人中最为常见。麦卡洛克女士说，人们更喜欢发送一个全新的信息，而不是用句号来结束一个句子。她说:“如果你是一个年轻人，你在给别人发送信息，打破你的想法的默认方式是把每个想法都作为一个新的信息发送。”

The full stop dates back around 2,300 years. It is an essential part of writing today. School teachers can put lots of comments in red ink on a student's writing if that student forgets to add the full stop at the end of his or her sentence. However, technology is changing the way we write. Most people now use abbreviations or acronyms in text messages. They might use the acronym 'LOL' instead of writing 'laugh out loud,' or the abbreviation 'fyi' rather than typing 'for your information'. Ms McCulloch says not using the full stop helps the writer save time. She also says that a full stop can make the writer look a little aggressive. Many people prefer to end a sentence with an emoji or emoticon instead of a full stop :-)

句号可以追溯到2300年前。它是当今写作的重要组成部分。如果学生忘记在句末加上句号，学校老师可以在学生的作文中用红墨水写很多注释。然而，科技正在改变我们的写作方式。现在大多数人在短信中使用缩写或首字母缩写。他们可能会用LOL来代替laugh out loud，或者用fyi来代替键入for your information。McCulloch女士说不使用句号可以帮助作者节省时间。她还说，句号会让写信人看起来有点咄咄逼人。很多人喜欢用表情符号或emoticon来结束一个句子，而不是句号:-)
