US scientists have performed an important reversal(逆转) of the ageing process in animal studies. They used a chemical to rejuvenate(使年轻) muscle in mice and said it was the equivalent(等同于) of transforming a 60-year-old's muscle to that of a 20-year-old — but muscle strength did not improve. Their study, in the journal Cell, identified an entirely new mechanism(原理) of ageing and then reversed it. Other researchers said it was an "exciting finding".

Ageing is considered a one-way street, but now researchers at Harvard Medical School have shown that some aspects can be reversed. Their research focused on a chemical called NAD. Its levels naturally drop in all cells of the body with age. The team showed this damaged the function of the cell's in-built power-stations, leading to lower energy production and ageing.

Experiments showed that increasing NAD levels, by giving mice a chemical which they naturally change into NAD, could reverse the sands of time. One week of youth-medication in two-year-old mice meant their muscles became similar to those of a six-month-old .

Dr Ana Gomes, from the department of genetics at Harvard Medical School, said: "We believe this is quite an important finding." She argues muscle strength may return with a longer course of treatment. However, this could never be a cure-all for ageing. Other aspects such as shortening of telomeres or damage to DNA would not be reversed.

Dr Gomes told the BBC: "Ageing is multi-factorial, it's not just one component(成分) we can fix, so it's hard to target the whole thing. I believe there is a lot of cross-talk in cells and energy is very important in a cell and likely to be a very big component of ageing that might cause some of the other things that happen with ageing."

68. From paragraph 1 we learn that ________.
A. bones can be transformed
B. muscle strength can be transformed
C. color can be transformed
D. muscle can be transformed

69. From paragraph 2 and paragraph 3 we learn that       
A. researchers think ageing is a one-way street.
B. NAD levels’ dropping could make mice become younger.
C. increasing NAD levels could make mice become younger.
D. researchers think any aspect can be reversed.

70. Dr Gomes will agree that              
A. we can target everything about ageing.
B. muscle strength may return over a longer course of treatment.
C. ageing could be cured.
D. energy is of little importance in a cell.

   While many Chinese overseas artists are switching to other more profitable fields, Huang Shanye, a painter of the Zhuang ethnic group, stands out as an exception. His art has gradually earned him fame over the course of his more than 20 years in the United States. He was even able to leave behind his steady job as an art teacher and fully devote himself to what he describes as a pursuit(追求) of beauty.

The common theme of Huang's many works lies in the combination of traditional Chinese elements and Western painting techniques. "I apply Chinese calligraphy(书法), paper cutting, facial makeup of Peking Opera -- all the things that I can find in traditional Chinese culture -- to Western oil painting," Huang said at an exhibition held recently in his home county of Montgomery, Maryland in the US, where friends and neighbors had come to view some of his work. 

One of Huang's works in the show, which had been featured on the exhibition's flier(广告传单), served as a good example. Titled In Harmony, the painting shows two green dragons facing one another on a golden plate -- a characteristic of Chinese tradition. Huang decorated the surface with the words "peace" and "dragon", both in Chinese and in English. Michele Cohen, director of the Betty Mae Kramer Gallery, pointing to Huang's In Harmony, says: "I think this work really shows how an artist can combine one tradition with another, and it really comes out in a mixed form."

In 1998, American composer Silas Huff met Huang at an exhibition and was moved by Huang's sketch Tapestry of Dreams, which was later realized into a large-scale work consisting of a dozen 1-by-1-meter panels of paintings describing the traditions and longings of Huang's people.

Inspired by the work, Huff composed a 25-minute symphony(交响乐), Spring Song Festival, made up of Chinese folk melodies. Ten years later when Huff and Huang reconnected, Huff was able to bring two ballet schools on board and create a ballet based on the symphony. The work was performed at LaGuardia Performing Art Center in New York in the spring of 2009, with Huang's Tapestry of Dreams as a background.

64. What is the theme of Huang’s many works?

A. The combination of traditional Chinese elements and Western painting techniques.

B. The difference between traditional Chinese elements and Western painting techniques.

C. The advantages of traditional Chinese elements and Western painting techniques.

D. The disadvantages of traditional Chinese elements and Western painting techniques.

65. We can infer _________.

A. Huff composed a 25-minute symphony, Spring Song Festival after he arrived in China.

B. Huff composed a 25-minute symphony, Spring Song Festival because he graduated in China.

C. Huff composed a 25-minute symphony, Spring Song Festival, because of Huang’s work.

D. Huff composed a 25-minute symphony, Spring Song Festival because of money.

66. Which is the best title of the passage?

A. A Pursuit of Beauty

B. The Life of an Artist

C. True Friends

D. The Differences of Art

67. Michele Cohen, director of the Betty Mae Kramer Gallery, _________.

A. thinks highly of Huang's In Harmony.

B. pays no attention to Huang's In Harmony.

C. wants to buy Huang's In Harmony.

D. criticizes Huang's In Harmony.
