能会认为父亲在祝贺他的儿子某事做得好，也许是通过考试或者是赢得比赛。你知道发生的事情是因为你明白父亲的肢体语言所表达的信息。在全世界，拍背部和微笑通常都意味着"做得好"。

肢体语言每天都被全世界不同国家的人使用。这是一种没有词语，由手势、面部表情和肢体动作组成的语言，它极大地丰富了--有时甚至取代了--口头语言。肢体语言就像其他任何语言一样，被用来交流各种态度和喜怒等感情，但是与口头语言不同的是，它不总是明确清楚的。某人高兴地跳跃是容易看到的，而挑起眉毛表示怀疑却更容易被人忽略。

People often use body language on purpose⑫. Someone who does not know the answer to a question⑬ will move their shoulders upwards⑭ away from their upper⑮ body and then let them fall, meaning"I don't know". However, body language can be unconscious⑯ as well. A person who is feeling uncomfortable or nervous will often hold their body in a very rigid⑰ manner and have a tight⑱ look about their mouths. They might also cross their arms and move in an abrupt way resembling⑲ a robot more than a human. They might not even realise how they are acting but their body language will tell anyone who cares to look closely enough how they are feeling. Body language can therefore make people's feelings more transparent⑳ as although we can lie with words, it is not as easy to do so with our bodies○21.

[第3段译文]

人们经常有意识地使用肢体语言。不知道问题答案的人会将肩膀向上抬起，然后再放下，表示"我不知道"。然而，肢体语言也可以是无意识的。一个感到不舒服或紧张的人经常会使身体处于非常僵硬的状态，嘴巴绷紧。他们也可能交叉手臂，走起路来像机器人一样笨拙，而不是像人。他们也许甚至意识不到自己的行为方式，但是他们的肢体语言将会把他们的感觉告诉任何喜欢仔细观察的人。因此肢体语言可以让人们的感觉更加外露，尽管我们可以用语言来掩饰我们的感受，但是用身体并不那么容易。

Learning to be aware of your body language○22 can be a very useful tool. For example, in a job interview, you will probably be feeling nervous but you won't want to appear to be in a state of○23 unrest○24. You will want to appear calm with as much dignity○25 as possible.
