1. Head
The head is thought to be the most important part of the human body. So a leader is often compared to a head (首腦). Thus we have Head of State or the head of a delegation.
The head is where the brain is located. It is naturally associated with ideas and intelligence. Very often, we need other people's ideas and opinions when we want to do something well. The is because two heads are better than one (三個臭皮匠頂個諸葛亮).
2. Eye
The eyes are extremely precious to us. That is why we say" Mind your eye (當心)! when we reminding someone to be careful.
Not only human beings and animals have eyes, many things also have" eyes"- the eyes of a ship, the eye of a needle, the eye of a typhoon, and so on.
3. Ear
The ear is the organ of hearing. A piece of light music is easy on the ear. (悅耳動聽). We are usually all ears (專心聆聽) for bit news.
When they think somebody is overhearing, English people use either of the two proverbs: Walls have ears (隔墻有耳) and Pitchers have ears (壺罐有耳). They also think that little pitchers have big ears(小孩子耳朵尖). Nice boys and girls respect other people. They will not secretly listen to others' private conversations.
4. Nose
The English phrase "face to face (面對面)" and its Chinese counterpart(對應) are exactly the same. But English people, to express the same idea, can say nose to nose instead. There is no such substitute in Chinese.
The word nose appears in many idioms. Here are two which are quite similar to their Chinese equivalents: lead somebody by the nose (牽著某人的鼻子走) and turn up one's nose at somebody or something (對某人或某物嗤之一鼻).
English people can say as plain as the nose in one's face (一清二楚) to mean "very obvious". May be to them, the nose is the most conspicuous part of the face.
5. Lip
We have two lips: the upper lip and the lower lip. If one's two lips are closed, one cannot speak. So it goes without saying that "don't open your lips (不要開口)" means " don't speak".
His lips are sealed. Are his lips really stuck together by wax or glue? No, his lips are sealed when asked about something that he must keep secret. Sometimes a top secret is betrayed because it has escaped someone's lips (脫口而出). Then the incident may become a piece of news that is on everybody's lips (眾口相傳).
6. Tongue
We all know we cannot speak without the tongue. So the tongue is closely related to speech. To hold one's tongue (保持沉默) means "to keep silent". A person who has too much tongue (太多嘴) is disliked by all, for he is too talkative. Mother tongue is not the tongue of a mother: it is a person's native language.
"Don't you have a moth below your nose (你鼻子底下不是有張嘴嗎)?" The Chinese say so to blame a person who did not say what he should have said. But this not the right way to express the idea in English. English people would say, "You have a tongue in your head, haven't you?"
7. Face
Face has to do with the idea of respect and dignity both in Chinese and English. You lose your face (丟面子) if you fail again and again, but a decisive victory will save your face (挽回面子) after all your failures.
When you feel unhappy, you pull a long face (拉長臉). The idea is conveyed in Chinese in the same way. But "about face (向后轉)" does not refer to the face. It is a military order to turn round and face in the opposite direction. It is the exact equivalent of " about turn".
8. Shoulder
The shoulders can bear heavy things. Your father has a great responsibility for the family on his shoulder. When faced with difficulty, the family should stand shoulder to shoulder (肩并肩) to overcome it. You should not turn a cold shoulder (不理睬) to your family members. Nor should you give your friends the cold shoulder (冷落朋友). Both expressions mean treating others coldly.
9. Back
A good host is hospitable to his guests. But, if guest is tiresome, the host is glad to see his back (他離開).
If your friend has done something really well, you may give him a pat on the back (輕輕拍背部) to show your appreciation.
If you turn your back on somebody (不理睬他人), you mean you do not like making friends with that person.
10. Heart
The heart is an extremely important organ inside the chest. It usually stands for something important or the centre of something, for example, the heart of the matter (問題的核心) or the heart of mystery.
Many other expressions make use of the word heart. A lover can be called a sweet heart (情人). The Purple Heart (紫心徽章) is a medal given as an honor to American soldiers wounded in battle.
If your friend is in trouble, you may encourage him by saying "Don't lose heart (不要灰心)."
