If the eyes are the windows of the soul, then the body is the mirror of our feelings.If we are feeling great, we may give our body signals(信号).lf we look at someone else's body, we can often tell how they are
feeling by their body signals. So reading body language signals is a great tool in daily communication.
In case(假使) you don't think that learning how to read and use body language
is important, here are some numbers for you. 7% of the information we receive is
from what people actually say, and 38% of the information we receive is from the tone(语气) and the speed of their voice; while 55% of the information we receive is from their body language.
These non-verbal(非口头的)  signals will help you a lot,  but you still need to focus on what people are saying. If you focus too much on their body language
signals,  you and the person may feel uncomfortable.
It is useful to be able to read people's body language, but it is useful to learn how to send the right signals and avoid the wrong signals, too. Body language may be given several interpretations. Many signals have different meanings, depending on the person and the situation. Be sure of it when you are trying to read  a
body language signal.
