Body language plays a big role in communication as it gives us messages about the other person that we can understand nonverbally, just basing the understanding on our feeling. There are four types of body language to be aware of.
Eye contact is one of the most direct and powerful facial expressions. Eyes are always talking. The use of eye contact varies significantly from culture to culture. In some regions, direct eye contact is often considered a sign of trustworthiness. So, if you're in America, you should know soft, attentive eye contact would convey honesty. However, a hard, unblinking stare will send a very different message, similar to the meaning of direct eye contact in some regions.
Gestures can be used to emphasize certain meanings. Pressing fingers together to form steeple（尖塔）shows interest and determination. Touching the nose or rubbing eyes indicates discomfort. A hand on the back of the neck may indicate you are not interested in a conversation.
Body posture can be positive or negative A firm handshake will give the impression of honesty. Folding arms across your chest is protective. People with arms folded, legs crossed and bodies turning away reject messages. A head held straight up signals a neutral（中立的）attitude. A head sidewards indicates interest. A head down is negative.
The position of speakers and listeners face-to-face, side-by-side or back-to-back, can send powerful messages. In a group, when the leader faces the group and turns toward the one who is speaking, this conveys strong attention When two people are communicating, competitors more possibly sit facing each other while partners sit side-by-side.
