1. There are many different ways of communications, such as letters, emails, or telephone calls. However face-to-face communication still is the most efficient way to communicate among people.

First of all, face-to-face communication is indispensable in situations such as a relationship. Lovers need body contact such as a hug and a kiss, which cannot be done in letters or emails. Although lovers can use letters or emails to communicate, being apart for a long time is definitely not beneficial to a relationship. Second, face-to-face communication is the most helpful way to express people`s behavior. People need eye contact and body language to express their feelings. Sometimes they are so happy or angry that they are out of words. At these times, there is nothing more efficient to express their cheer or sadness than a big hug or dancing. If a person visits a foreign country, his language is not fluent; gesulations might help him or her understand more quickly. He can order simply by pointing our fingers to the menu when he is in a restaurant.

Finally, by face-to-face communication people can get direct response from others. When they talk with their friends, they can immediately gain feedback from their verbal response, body language and facial expressions. Based on these responses, people know what the next step is to take, such as how to carry on the conversation. Sometimes, speaking words and body languages may not mean the same thing.

Although people can hear words through a telephone conversation from friends, people do not always know what friends really mean. This is also true in criminal inspections. Police inspectors would judge whether the suspect is telling the truth through his or her body languages; therefore, that helps quickly solving a criminal case. Thus, face-to-face communication is more perceptible and helps us understand a speaker`s true feeling better than other ways of communication.

In brief, communication is very important for us, especially face-to-face communication. Face-to-face communication is good for people to understand each other better. Also, it is more visible, more direct and more effective than any other ways.
