Body language can be very useful when people do not share○27 a common spoken language. For example, in foreign countries, it is very easy to purchase something simply by smiling and pointing at what you want○28. On the other hand○29， you can also easily show what you don't like by shaking your head. You can negotiate○30 the price by using your fingers and even ask questions by using your hands to outline○31 the shapes of things you want - although this can cause confusion○32 and a few laughs too！,○22be/become aware of 知道，了解，意识到

[第4～5段译文]

学会了解你的肢体语言可能是一个很有用的方法。例如，在面试的时候，你可能会觉得紧张，但是你不想表现出不安的样子。你想表现得平静，并且尽可能优雅。只要双臂不交叉，你看上去就会更自信。语言不通时，肢体语言就非常有用。例如，在外国，要想买东西的话，只要面带微笑并且指着你想买的东西就可以。另一方面，你也可以通过摇头便可容易地表示出你不喜欢。你可以用手指讨价还价，甚至可以用手比划出你想要的东西的形状来问问题--尽管这会让人迷惑不解，还会引人发笑！

However, body language can sometimes be ambiguous○33. Although every culture around the world uses the same gestures and expressions○34， they use them in different ways○35. For example, an American tourist at a German hotel might give an "OK" sign by making a circle with his fingers. Unlike in America where this sign means everything is fine○36， in Germany, this gesture can cause offence○37. Another example is that in most cultures to nod one's head means "Yes" and to shake one's head means"No" while in some cultures the opposite is true！○38

Regardless of○39 these differences, experts agree that across the globe there is one form of body language that receives universal approval○40 - the smile. Smiling has a high success○41 rate so never be afraid to use it - even when you're nervous - and especially in foreign countries！
