We are always using body language in our daily lives. When we have a conversation with someone, we may use more body language than words. However, the same body language may mean different things in different countries. That's why people sometimes cannot understand each other.
Pointing to one part of the body can have different meanings in different cultures. For example, in the US, people point to their heads when they think someone is clever. However, in Europe it means "He or she is stupid or something is wrong with his or her head". In our Chinese culture, nodding our heads up and down means "Yes" and shaking our heads from side to side means "No". However, in some parts of India, Greece and Türkiye, they mean just the opposite.
In England or the US, when you raise your hand and make a circle with the thumb（拇指）and the second finger, it means "Everything is all right". However, if we do this in France or Belgium, it means "You are worth zero". In Greece or Türkiye, we should not make this gesture. Or people will think we are very rude.
The meaning of gestures can also change over time. In the 1960s, the "V" sign meant "peace". However, during World War Ⅱ, it meant "victory". In Greece, it is an insulting（侮辱的）sign. It will be very rude of you to make this gesture in front of a woman.
Although the meaning of body language is different, there are some expressions having the same meaning throughout the world, such as smiling and crying.

这是一篇介绍不同文化中肢体语言含义异同的说明文，逐题解析如下：
20. 根据第一段关键句“However, the same body language may mean different things in different countries.”，可知A选项表述正确；B选项文中无相关表述，C选项第一段没有提及语言差异的内容，D选项和第一段最后一句“people sometimes cannot understand each other”的表述相悖。
21. 根据第三段第一句“In England or the US, when you raise your hand and make a circle with the thumb and the second finger, it means "Everything is all right"”，该手势含义和题干的“Everything goes well”表意一致，对应正确选项。
22. 用排除法判断：A选项和首段“我们日常生活中一直在使用肢体语言”的内容矛盾；B选项和第四段首句“The meaning of gestures can also change over time”的内容矛盾；D选项和第二段举例的“美国和欧洲用手指向头部的含义完全不同”的内容矛盾；根据第二段“在中国摇头表示‘No’，但在印度、希腊部分地区含义完全相反”，可推知希腊部分地区摇头的含义是“Yes”，C选项表述正确。
