In the last century, differnet natural disasters have robbed several cultural heritage(遗产) from us. On WeChat, some people say, “What a pity that we cannot see the damaged parts of the wonders anymore.” But people can see them in a new way---through a video game. In this game, the player can travel to one city after another and enter the buildings exactly like they are in reality, and see the wonders as they were before the fire.

Maybe digital technology(数字技术) could help protect cultural heritage better. This idea dates back to the 1990s and the necessary technology has continued to develop since then. By scanning(扫 描) the ancient buildings, building 3D models, as well as measuring everything, engineers can make a copy exactly as the real one.

As computers and smart phones are popular, the digital copy has great value. First, it allows tourists to feel the cultural heritage without touching them, which helps protect them. The virtual tour of Dunhuang Grottoes(敦煌石窟) is a good example of this as tourists can view the paintings without standing near them.

Second, it can make the cultural heritage more famous by spreading information about them through the internet. In 2000, a virtual tour of the Dunhuang Grottoes became very popular at the Hannover World Expo, which increased the number of foreign tourists visiting the site in the following years.

Last, it stores all the information of the cultural heritage. Even if the real ones are damaged one day, people can still know what they were like and can build a new one if wanted. Of course, however exact a model, it is not the real one.

Maybe we will have better technologies in the future, but the digital technology offers a practical way to protect cultural heritage at the moment.

Everyone has traits (特性) that make us who we are. We have physical traits, like red hair, long legs and funny-looking toes. We also have character traits including humor, warmth, creativity and so on.

Certain physical traits are fully inherited (遗传), such as blue eyes and knobby knees. About 25,000 to 35,000 genes (基因) are in a single cell in the human body. These genes carry the traits that are passed down genetically from parents to their children.

Many traits exist between inheritance and development — the interaction with environment. One example is body shape. It tends to be passed down from parents. But once diet becomes a factor, environment begins to play an important role in how the body develops. Body shape is a trait that is a mixture of inheritance from parents and influence of environment.

So lots of our most important traits have been learned, rather than inherited. For example, if you’re really great at video games, it’s not because your parents passed down the skills in genes. It’s because you have practiced a lot of video games and developed those skills yourself. If you have kids who turn out to be great at video games, it is because they put in the hours, learned the skills, and memorized the moves that are necessary to play the video games well.

Of course, some of us have brains that are more advantageous to video game playing. Say you were born with a large and powerful part of the brain that controls your hand-eye coordination. That is inherited. What you do with it, how you choose to develop that advantage, is up to you.

You can pierce your nose or get a tattoo (纹身) — it doesn’t matter how much you change your body during the lifetime. None of those things will turn into genetic material to be passed down to the next generation. However, if your children grow up in an environment with role models who are pierced and covered in tattoos, they are more likely to get piercings and tattoos!

1.　　　　　　　　　 is a physical trait that is fully inherited.

A.The eye color B.The special diet

C.The body shape D.The pierced nose

2.What does the underlined word “That ” refer to ?

A.Video game playing. B.Advantageous brains.

C.The shape of your brain. D.Your hand-eye coordination.

3.According to the passage, the writer believes that 　 　　 .

A.character traits can hardly change during the lifetime

B.the skills of video game playing are passed down to kids

C.a kid’s hand-eye coordination isn’t related to inheritance

D.environment plays an important role in traits development

4.Which of the following would be the best title for the passage?

A.Why are Traits Important? B.How does Inheritance Influence Traits?

C.Where do Traits Come from? D.What are Physical and Character Traits?
