DNA is the whole “map” of the human body. It is something that all humans 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 genes 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 don’t 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 (有吸引力的), or stop sick people getting jobs.When did Mr. Mendel discover why we look the same as other people in our family?

Why play games? Because they are fun, and we can learn even more while playing. Following the rules, planning your next move, acting as a team member — these are all “game” ideas that you will come across all through your life. They can help you in different ways.
Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are very interesting. But perhaps more importantly, they translate part of life into exciting games that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating (合作).
Many children’s games have a practical side. Children around the world play games that prepare them for work they will do as grown-ups. For example, some Saudi Arabian children play a game called bones, which improves the hand-eye coordination (协调) needed in fishing.
The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competitions. People who watch the event (比赛项目) know that a gold medal is a win for the whole country, not just the athlete who got it. For countries experiencing natural disasters (灾害) or wars, an Olympic win can mean so much.
Sports games are also an event that unites (团结) people. Football is the most popular sport in the world. People all over the world play it — some for fun and some for a living. Nicolette Iribarne, a Californian football player, has discovered a way to spread hope through football. He created a foundation (基金会) to provide poor children with not only soccer balls but also a bright future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other parts of your life. What are children expected to learn when they play games?
| A．To act as a team leader. | B．To follow the basic rules. |

In 50 years of traveling, Colin McCorpuodale has visited every country in the world except three. And everywhere he goes, he sends himself a postcard. He always chooses a postcard with beautiful scenery (风景). Usually he writes just a short message to himself. However, he wrote an interesting story on his latest one, from the Malians Island.
Mr. McCorpuodale lives in London. On one of the walls in his room, you can see a large map of the world. There are hundreds of little red pins (大头针) stuck in it. “These pins mean a lot to me.” says Mr. McCorpuodale, “I follow the rule. I’m allowed to stick one in only if I’ve been in a place for more than 24 hours.”
Naturally, Mr. McCorpuodale has his favorite places. New Zealand, he describes as “a wonderful country”. About China, he says, “This is the country in the world which is completely different. There is no European influence.”
