To promote     1     (variety) applications of Dunhuang art patterns in daily life design and achieve the development of cultural heritage represented by Dunhuang art patterns, the Chang Shana Design Award in 2021     2     (announce) on January 21.

Chang Shana, an outstanding designer and educator in China, was just 13 when her love affair with Dunhuang     3     (begin). Born in France, she returned from Paris with her father and involve themselves in the cause   (事业) of cultural heritage. She was much     4     (young) than the other members in the conservation and research team at the Mogao Caves,     5     leader was her father Chang Shuhong (1904 –1994),     6     noted painter and director of the Dunhuang Academy. Chang has spent her entire life     7     (carry) on her father’s devotion to Dunhuang. She applied the classic patterns     8     her own modern designs in a creative way after conducting research into the variety of patterns     9     (find) on the murals (壁画).

In the hope that more designers can understand and use the Dunhuang art patterns     10     (proper), the competition is also meant to spread Dunhuang culture practice the “Silk Road Spirit” and promote cultural exchanges along with the Belt and Road Initiative.

5 . Native to forests of Central and South America, glass frogs in the Centrolenidae family get their name from their skin and muscles that help them be perfectly fit to live in their jungle environment. Turn the frogs over, where the effect is the most impressive, and you’ll make out their hearts, livers, and other organs through their hyaline stomachs.

And in a study published in the journal Science, researchers have discovered an amazing mechanism (机制) the animals use to become so clear.

When glass frogs go to sleep, they take in 89 percent of their brightly colored red blood cells into sacs (液囊) in their livers, which reflect incoming light and make the frogs appear nearly unseen. With their red blood cells out of view, the frogs become twice to three times more clear -a trick scientists believe helps the animals avoid being killed and eaten by their natural enemies.

“The trick is really hard to do, because their tissues are full of things that take in and spread light. And transparency (透明) is normal for many creatures in water, but hard on land,” says study co-author Jesse Delia. “Red blood cells also take in a lot of light, and we found that the frogs can actually hide themselves by packing them into the liver.”

Not only are the findings interesting, but the researchers attach great importance to them. That’s because many red blood cells in one place usually form a clot (血块), which can block and lead to a potentially life-threatening condition. But the frogs can seemingly clot and expand their red blood cells at will — without any negative effects. This may mean the animals already have what medical researchers have been seeking for decades: a biological mechanism which prevents too much bleeding while also preventing too much clotting.

1. What does the underlined word “hyaline” mean in paragraph 1?

A．See-through.

B．Powerful.

C．Narrow.

D．Good-looking.

2. What is the new discovery about glass frogs?

A．The frogs fit in their environment better.

B．Sacs filled with red blood cells make the frogs clear.

C．Red blood cells in the frogs’ liver reflect light.

D．The frogs are able to take in a lot of bright colors.

3. What does Jesse Delia think of glass frogs’ trick?

A．Interesting.

B．Unusual.

C．Normal.

D．Annoying.

4. Why do the researchers consider the findings important?

A．They help cure serious diseases.

B．They are a blessing for wild animals.

C．They can lead to advances in medicine.

D．They will prevent all clotting and bleeding.

6 . People may typically think of memory as the recollection of the past. Memory enables people to learn from past experiences and apply that knowledge in present cases. It is an important part of our identity. So is culture, the way of life specific to a group of people.

Cultural memory is the constructed understanding of the past that is passed from one generation to the next through text, oral traditions, monuments and other symbols. Cultural memory is often amassed in objects, such as museums or historical monuments. To understand culture, humans access a mass of cultural symbols, such as books. Artifacts (历史文物) of the past provide insights into where we came from. Libraries and the Internet keep a seemingly boundless amount of data on what it means to be part of a culture. Cultural memory is the longest-lasting form of memory.

Like all forms of memory, cultural memory has important functions. For example, it makes the experiences a nation owns clear. It provides us with an understanding of the past and the values of the group to which we belong. Besides, it creates a form of shared identity and a means for communicating this identity to new members. The most powerful forms of cultural memory may involve memories of past disastrous experiences undergone by groups of victims. For example, in Russia, their role in World War II —in which tens of millions of Russians were killed — is still an important part of modern Russian identity. Because all groups have cultural memory, it can bring about a spirit of resistance or survival among threatened groups.

The main function of cultural memory is not to recall the past, whether it is good or bad. Rather, it is to use knowledge of past experiences to avoid making the same mistakes again and again. Aleida Assmann, a professor who has worked on memory theory since the 1960s, calls this “remembering forward”. Cultural memory enables people to adapt to their culture; it enables cultures to adapt to new circumstances by keeping traces (痕迹) of what worked in the past.

1. What is the function of the first paragraph?

A．Reporting a discovery of cultural memory.

B．Leading to the concept of cultural memory.

C．Introducing the importance of memory in identity.

D．Making a connection between memory and culture.

2. Which can replace the underlined word “amassed” in paragraph 2?

A．Stored.

B．Ignored.

C．Damaged.

D．Created.

3. Russia is mentioned in paragraph 3 to indicate ______.

A．the features of cultural memory	B．the formation of cultural memory
C．the role of big events in Russian identity	D．the impact of cultural memory on identity

4. What is cultural memory mainly expected to do?

A．Pass previous wisdom down.	B．Keep traces of history.
C．Get people to know about the past.	D．Remind people of their identity.

A group of researchers and scientists from home and abroad are working together    1    (record) and collect digital images of the cultural relics from the Mogao Caves, in an effort to promote the    2    (appreciate) of China's ancient cultural heritage. Nearly 500,000 high-quality digital photographs    3    (produce) since the international project started in 1994. The Mogao Caves, as    4    key stop along the Silk Road throughout China’s ancient history, have long been a meeting point for different cultures. The caves are    5     international as they were at the time    6    people travelled the Silk Road.

The group hopes to promote even    7    (wide) interest around the world in China’s ancient history, culture and traditions. They also hope to further educate people about the importance of    8    (protect) historic and cultural relics for future generations to understand and appreciate. As one researcher working    9    the project explains, “Appreciating one’s own cultural heritage    10    (be) very important for understanding oneself. Appreciating the cultural heritage of other countries is very important for international communication and understanding.”
