A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.

    Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.

Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳動(dòng)物) have unexpectedly been discovered in the skin of mice.

“No one had ever looked,” explained Randall Johnson, a biologist researcher.

Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.

   “We have no reason to think that they are not in the skin of people too,” Johnson said.   These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷爾蒙) even after hours of such low oxygen.

   These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (貧血癥) without injecting drugs, which make up a multibillion-dollar market, Johnson said.

Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.

The scientists detailed their findings in the April 18 issue of the journal Cell.

B. People have to surf the Internet to read detailed findings.

C. It has been proved that these findings help treat lung diseases.

51. What is Johnson’s attitude to the application of the findings to the athletes’ training?

A. Negative                  B. Doubting                  C. Positive             D. Hesitating

52. The best title of the passage may be _______.

A. Great Findings Benefits Athletes A Lot

B. Frogs And Mice Are Distant Relatives

C. First Known Animal Breathes Through Skin

D. Humans Might Sense Oxygen Through Skin

It has long been known the ancient Egyptian rulers, or pharaohs, were buried with great ceremony and lavish treasures that were to be used in the other world.

Unfortunately, until 1922 no remains of any of the pharaohs or their treasures had ever been found. In that year, however, an archaeologist named Howard Carter and his sponsor, Lord Carnavon, were at last successful. They found the tomb of King Tutankhamen, who was buried 3,200 years ago. King Tut’s tomb was the first fully preserved burial site to be uncovered in Egypt’s Valley of the Kings. The two men found the tomb to contain wonderful treasures. Gold figures and magnificent furniture decorated with gold were found in the myriad of secret rooms and tunnels within the pyramid.

The only disappointment for Howard Carter came when he found that King Tut’s body was nothing but dust. Apparently a mistake had been made when the king’s remains were mummified (使成木乃伊). Carter did, however, find 143 pieces of jewelry within the mummy case, mostly made of gold and precious stones.

Actually, despite all the publicity about the remarkable finds in his tomb, Tutankhamen’s reign (統(tǒng)治時(shí)期) as pharaoh was short and relatively uneventful. He died when he was just 18 years old.

There is an interesting story that goes along with King Tut’s tomb. According to legend, a powerful curse was placed in it. This curse was to descend on anyone uncovering Tutankhamen’s burial place. Not very long after the discovery, Lord Carnavon, along with several of the workmen, died suddenly.

    When gaming becomes an obsession it can become dangerous. In Hong Kong, a seventeen-year-old boy died as a result of playing his favourite game in the café where he worked. After working for eight hours, he often stayed at the café and played Diablo II. On some nights he slept for only two hours. In May 2002, he was found unconscious at a computer after playing all night. When he died later in hospital, doctors said it was because he was exhausted.

    In Korea, the dangers can come from other gamers. In the virtual world of Lineage, gamers can create new characters for themselves. High school students can become very powerful fighters and leaders. They play against doctors, businessmen and even members of dangerous gangs. But sometimes things that happen in the game affect real life. Gamers have been beaten up in real life by people they have killed online!

56. How many people play Lineage when school and work are over every day in South Korea?

57. What do people do in the virtual world of Lineage?

58. The online games mentioned in the passage are ________.

59. What does the underlined word “exhausted” mean?

60. What does the passage mainly talk about?

They ________ the distance and the communication problem for people visiting their city.

A. drew attention to B. used up        C. washed away    D. dreamed of
