    It’s often said that the rise of social media has revolutionized (彻底改变) communication. With smartphones and social networking apps, we can write to our family and friends whenever we like. But while social media has brought us convenience, it also has its problems, such as misunderstandings in communication.

Quite often, people misunderstand what’s written on social media. According to a story published on The Conversation on March 8, sarcasm (讽刺), in particular, can be very difficult to notice in a written message.

Sarcasm is a kind of irony (反语): It’s when we say something, but really mean the opposite. For example, a message from a friend the day before a math exam that says “I’m so looking forward to tomorrow!” is obviously sarcasm.

Sarcasm before the rise of social media and mobile phones was mostly used in speech and face to face. That made sarcasm easier, because you could accompany your words with a facial gesture and a tone (语气) of voice that would help others get your message. You had a good chance of being understood and receiving a laugh or an understanding glance.

And yet when we text or write something online, a lot of that information goes missing. “There are no facial hints, no tones or maybe even a delayed response if a person can’t text you back immediately,” wrote The Conversation. “And if you don’t know the person all that well, there goes your last possible hint: history.”

To help avoid misunderstandings, people who use platforms such as Twitter often include the hashtag ﹟sarcasm – although this is like having to explain a joke when people don’t laugh at it, which destroys the point of sarcasm in the first place.

And it isn’t only sarcasm that can get lost in electronic communications. It’s also hard to notice things such as indifference (冷漠).

“One of the problems with digital communication, when it relies purely on text, is that this sucks (抽离) the empathy (情感共鸣) out of the communication. So it can lead to miscommunication,” linguist Vyv Evans, author of The Emoji Code, told USA Today. “This is where emojis come into their own. They put the body language back, so people can better read emotional intent (目的).”

However, even though there are hundreds of different emojis(表情符号) to choose from, there’s still no replacement for good old-fashioned face-to-face communication.
