A small piece of fish each day may keep the heart doctor away. That’s the finding of an extensive study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day than those who never ate fish.

The Dutch research is one of three human studies that give strong scientific backing to the long-held belief that eating fish can provide health benefits, particularly to the heart.

Heart disease is the number-one killer in the United States, with more than 550, 000 deaths occurring from heart attacks each year. But researchers previously have noticed that the incidence of heart disease is lower in cultures that consume more fish than Americans do. There are heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.

During the last two decades, 78% of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol levels.

One of the most popular American singers of the twentieth century was Elvis Presley. He made the rock ”n” roll music popular all over the world, He sold millions of records and made many successful films, and he helped change the direction of popular music in the 1960s.

Elvis Presley was born in a poor family in 1935, His parents were simple country people who often took him to church, where he learned to sing, and he never forgot the kind of songs that he used to sing in church as a child.

When he was young, Elvis moved from Toledo to Memphis in Tennessee, where he attended high school, but he was not a good student, His only real interest was singing. He began to sing in the style that is called “country and western”.

In 1955 he recorded some songs for his mother’s birthday. The people at the recording studio liked his singing and his music. It was country and western music, but it also sounded a little like the music which black people used to sing in the American South. It was called “blues”.

Shortly after that, Elvis met Tom Parker, who became his manager and arranged (安排) concerts for him across the United States and new recordings as well. Soon Elvis became famous around the country. Later Elvis went to Hollywood and began to appear in films such as Love Me Tender and King Creole.

But Elvis found it difficult to live with success. Like many other famous people, He began to take drugs and his health started to suffer. When he died at an early age of 42 in 1977,his many millions of fans were shocked, “The King Is Dead!” the newspaper said, But today his memory and his music live on and will always be remembered as the King of Rock “n” roll.

Ping-pong, or table tennis, might seem like an ordinary game to play with friends or family. But it holds a special place in China-US relations, as it has helped both countries get along for the last 50 years. This has been called “ping-pong diplomacy （乒乓外交）”.

Judy Hoarfrost was just 15 years old when she was sent from the US to China as part of a nine-member table tennis team. The year was 1971, and for the past 20 years, relations between China and the US had been unfriendly.

But as the team toured around China, things started warming up. Hoarfrost even got to meet then-Premier Zhou Enlai. “The most unforgettable moment was Zhou shaking hands with me and looking into my eyes,” Hoarfrost told China Daily. “You have opened a new page in China-US relationships.” Zhou told the team.

In the years that followed the historic visit, ties between the two countries started to blossom.Diplomatic relations between the US and China were fully established （建立） in 1979.

Players from both countries believed strongly in the idea of “friendship first, competition second”. To this day, many of them remain friends. Hoarfrost thinks we should remember ping-pong diplomacy in order “to understand the importance of people to people exchanges in establishing bonds , human bonds between peoples.”

Seeing tension （紧张局面） between two of the world’s biggest powers in recent years, Hoarfrost said China and the US should work together. “We have so much in common, and we need to build on what we have in common,” she added.
