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 (首脑). 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 (三个臭皮匠顶个诸葛亮).

2. Eye

The eyes are extremely precious to us. That is why we say" Mind your eye (当心)! 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. (悦耳动听). We are usually all ears (专心聆听) for bit news.

When they think somebody is overhearing, English people use either of the two proverbs: Walls have ears (隔墙有耳) and Pitchers have ears (壶罐有耳). 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 (面对面)" and its Chinese counterpart（对应） 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 (牵着某人的鼻子走) and turn up one's nose at somebody or something (对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 (不要开口)" 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 (脱口而出). Then the incident may become a piece of news that is on everybody's lips (众口相传).

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 (你鼻子底下不是有张嘴吗)?" 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?" liuxuepaper.com
