阅读下面短文并回答问题,然后将答案写在横线上(请注意问题后的词数要求).

     Have you ever been in the situation where you really didn't believe what someone was saying? Did

you have a sense that something wasn't true or a feeling that all was not right? Perhaps they were saying

"Yes" yet their heads were shaking "No".

     The difference between the words people speak and our understanding of ________ comes from

nonverbal communication, otherwise known as "body language". Body language includes body movements and gestures (legs, arms, hands, head and body), posture, muscle tension, eye contact, skin coloring,

even people's breathing rate and sweat. Additionally, the tone of voice, the rate of speech and the pitch

of the voice all add to the words that are being used.

     By developing your awareness of the signs and signals of body language, you can more easily

understand other people, and more effectively communicate with them. There are sometimes subtle(微妙的)-and sometimes not so subtle-movements, gestures, facial expressions and even shifts in our whole

bodies that indicate something is going on. We have ways of talking, walking, sitting and standing and

they all say something about us, and whatever is happening on the inside can be reflected on the outside.

     By becoming more aware of this body language and understanding what it might mean, you can learn

to read people more easily. This puts you in a better position to communicate effectively with them.

What's more, by increasing your understanding of others, you can also become more aware of the

messages that you convey to them.

     There are times when we send mixed messages-we say one thing yet our body language reveals

something different. This nonverbal language will affect how we act and react to others, and how they

react to us. Therefore, in order to communicate more effectively, we should learn the signs and signals

of body language correctly.
