Technology has no doubt made drastic changes in our modern life, and the impacts are taking place anywhere-cell phones, the Internet, modern transportations. Some hold the view that these changes are doomed to undermine the communication between people, but I believe that taking advantage of technology we have achieved a remarkable improvement of human interaction.
 
First, in the old days, lack of effective transportation, people had great difficulties in sending messages and traveling, while advanced technology  has removed away the obstructions and limits that block efficient communications. For example, in the wartime hundreds of years ago, messengers had to ride horses across countries to give word of victory, in sharp contrast, today, we can access to the latest global news through newspaper, smart phones and computers. Besides, compared with Marco Polo's years travel from Italy to China, it only takes seven hours flight from Beijing to Rome. Modern transportations have shorten the distance to make a smaller world where people can easily connect to each other. Moreover, video conference permits businessmen to settle a deal in their own offices, which renders long distance flight unnecessary.
 
Additionally, utilizing the modern technique human being has developed a variety of ways that make communication extremely convenient, which is unconceivable to the ancient residents. For example, we can post and share our updates on the Facebook, the intricate social network that fabricates seamless connection between friends, family, and even celebrities. Instead of making schedules ahead and sitting in the office, students only have to send e-mails indicating their confusions to the professors. Those mechanism sending instant messages contributes to save a great deal of time for people. Moreover, ordinary people’s voices, unprecedentedly,  can be heard by residents all across the world simply by uploading a video on the Youtube. Thanks to the technology, conversations are getting increasingly efficient, instant and convenient.
 
However, excessive reliance on the Internet and technological devices would likely preclude actual human contacts. For example, modern residents, especially the young ones, have grown an emotional attachment to the virtual world on the Internet. As a result, they refuse to get back to the reality talking with actual people. Also, some high technology video games that can simulate real sport scene keep kids in the door playing alone instead of hanging out with their friends.
 
It is true that the Internet addiction would build a shield against human contact, yet, throughout the long history, communications have never been so efficient and convenient. Although some problems concerning the side effects remain unsolved, we cannot deny all the contributions that modern sciences have made to superior human connections, because without them, social life would be like taking place on isolated islands.
