根据文意及首字母提示填空
Body language is used especially to e        feelings. For instance if we do not like someone, it is often d      to say that directly to the person. However we can make it clear either intentionally or unintentionally（有意或无意地） t         body language. The opposite is also true. We may say that we ARE angry through words yet our body language may be saying loud and clear that we are n      . This can be very confusing for the receiver. This is usually described as giving out double messages - one message in words and an o      message in body language. It is also difficult to lie or cover up our f      through body language. People may give their true feelings away by not being aware of their body language. Research has i         that most people pay more attention to, and believe more readily, their impression of how a person acts through body language t        what is said through words. As a consequence we tend to doubt, or put a question mark behind, the spoken words if they do not correspond with the language of the body .
