DNA is the whole “map” of the human body. It is something that all human have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.

People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They’re written in the DNA with a special language.

In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell(细胞) to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.

Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way, just to make people more attractive(吸引人的), or stop sick people getting jobs.

Body language is the quiet, secret and most powerful language of all! It is said that our body movements communicate about 50 percent of what we really mean while words only express 7 percent. So, while your mouth is closed, your body is just saying..

Arms. How you hold your arms shows how open and receptive(能容纳的) you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of anything. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you're unhappy!

Head. When you want to appear confident, keep your head level（水平）. However, to be friendly in listening or speaking, you must move your head a little.

Legs. Your legs will move around a lot more than usual when you are nervous or telling lies.

Posture (姿势). A good posture makes you feel better about yourself. If you are feeling unhappy, you usually don't sit straight, with your shoulders inwards. This makes breathing more difficult and makes you feel nervous or uncomfortable.

________________________ Face. When you lie, you might put on a false face. But that expression would not last long.　 And your true emotions such as happiness, sadness, fear and so on will come through.

1. When someone is keeping his arms behind his back, he tries to tell you that ________________________________________________.

During the 2016 Rio Olympics, people were surprised to see the round, purple marks on the body of the famous American swimmer Michael Phelps. What happened to him? In fact, he just visited a doctor of traditional Chinese medicine （TCM）and had “cupping”（拔火罐）.

Massage（按摩）and acupuncture（针灸）are two other important kinds of TCM. Chinese massage can make you relaxed and fresh. In acupuncture doctors put long needles（针）into the patients’ heads, faces, arms...It takes away pain, though the loo is funny.

TCM is an important part of Chinese culture. The earliest medical classic in China, Huangdi’t Classic on Medicine, came out more than 2,000 years ago.

Instead, he may give you just a food plan and right ways to eat.

But TCM thinks it’s wrong Here are the correct ways ：Sit down to cat, While eating, turn off the TV and get away from the work desk ;Eat seasonal foods,Do not miss any of the three meals. Also, get your body moving often, just as the saying goes,“Running water1s never stale.”

The expression “Go for it!” is a way of encouraging someone to try something. It means you should not worry about failure or be too careful. You should take a chance and be brave.

“Go for it!” gets its name from football. But it is not the football played in most countries such as England, France or Japan, but the kind of football played in the United States and Canada.
