Parties and social gatherings no longer excite us the same way they once did. This is not due to a lack of desire to socialize, but the smartphone.
At parties, more people are on their smartphones than on their drinks. According to a recent International Data Corporation study, well over half of all Americans have a smartphone and reach for it the moment they wake up, keeping it in hand all day. In addition, too much of society is using smartphones while driving and as a result getting into car crashes. 34 percent of teens admit to text while driving, and they confirm that text messaging is their number one driving interruption. People's attachment to their smartphones is unbelievably becoming more important than the lives of themselves and others.
Just as drivers dismiss the importance of focusing while on the road, many people also fail to recognize the significance of human interaction. When with their friends, some people pointlessly check or send text messages in the presence of a friend, which sends a message to that friend: the person I am texting is more important than you. In addition, relying on our smartphone to make friends does not give us the same advantage as being able to make new friendships in the real world. Face-to-face conversations will give us much stronger communication skills in the long run.
As many people risk their lives and the lives of people around them just to send a text or mindlessly check their massages, smartphones are in many ways more dangerous to people. The quality of this technology is de-advancing societal achievements and weakening the value of communication. Not only is the smartphone affecting our desire to interact (交流) face-to-face but it is also lowering society's ability to communicate.The purpose of this text is to ______.
