English reading comprehension translation for postgraduate entrance examination in 2008;

In the early 1960s, wilt chamberlain was one of only three people in the National Basketball Association who were over 7 feet tall. But if he had played last season, he would have been one in 42. Over the years, great changes have taken place in the physical condition of athletes in major professional sports, and their managers are more willing to adjust their sportswear to adapt to their bigger and taller bodies.

Although this movement trend may blind an unrecognized reality: Americans have basically stopped growing. Although people today are 2 inches taller than before 140, especially those who were born in the United States for many generations, it is obvious that in the early 1960s, they have reached the height limit. They can't grow any taller. "Under this genetic and environmental condition, the whole person has grown to the extent that we can," said William Cameron Chumlea, an anthropologist at Wright State University. Take NBA players as an example, their height growth is mainly due to the recruitment of players from all over the world.

The growth of height generally stops after the age of 20, and development needs energy and nutrition, among which protein is used for tissue growth. At the beginning of the 20th century, malnutrition and childhood diseases hindered all-round development. However, with the promotion of healthy diet, children and adolescents increase by about 1.5 inches every 20 years on average, which is the trend of growth and height. According to the CDC data, the average height of people (5 feet 9 inches for men and 5 feet 4 inches for women) has not changed much since 1960.

Generally speaking, there are many advantages to avoid being too high. Older babies have more problems passing through the birth canal during childbirth. Moreover, even though humans have been walking upright for millions of years, our feet and backs continue to face great pressure, which comes from the upright posture of our feet and huge limbs. "Some limitations are caused by the genetic structure of individual organs," said William Leonard, an anthropologist at Northwestern University.

Gene maximization can be changed, but don't expect it to happen immediately. Claire C. Gordon, a senior anthropologist at the Natick Military Research Center in Massachusetts, said. Make sure that 90% of the recruits don't need to change their uniforms and workstations. She said that unlike those basketball suits, the length of military uniforms has not changed for a long time. If you need to design a new device to predict human height in the near future, Gordon said, basically, "you can use the current data and feel very confident."

In the early 1960s, wilt chamberlain was one of only three players in the National Basketball Association (NBA) who were over 7 feet tall. However, if he had participated in last season's competition, he would have been one of 42 people. Over the years, great changes have taken place in the organizations engaged in major professional sports, and managers are very willing to adjust team uniforms to adapt to more and more larger and longer frameworks.

However, the trend in sports may hide an unrecognized fact: Americans have generally stopped growing. Although today's height is usually about two inches higher than that of 140 years ago, today's people, especially those who were born in families that have lived in the United States for many generations, obviously reached their limit in the early 1960 s. They can't grow any taller. William Cameron Chamley, an anthropologist at Wright State University, said: "In today's general population, we have gone far enough at this genetic and environmental level." . Take NBA players as an example. It seems that their height increase is due to the increasingly common practice of recruiting players from all over the world.

Growth rarely lasts beyond the age of 20. It needs heat and nutrition-especially protein-to nourish the expanding tissues. At the beginning of the 20th century, malnutrition and childhood infection became obstacles. However, with the improvement of diet and health, the height of children and adolescents increases by about 1.5 inches every 20 years, which is called the long-term trend of height. However, according to the data of the Centers for Disease Control and Prevention, the average height-5 feet 9 inches for men and 5 feet 4 inches for women-has not really changed since 1960.

From a genetic point of view, it is good to avoid being tall. During childbirth, it is more difficult for older babies to pass through the birth canal. In addition, even though human beings have been upright for millions of years, our feet and backs are still struggling with bipedal posture, and we can't easily bear the repeated pressure exerted by our big limbs. William Leonard, an anthropologist at Northwestern University, said: "The genetic structure of an individual organism sets some real limits.

The gene maximum can be changed, but don't expect it to happen soon. Claire C. Gordon, a senior anthropologist at the Natick Military Research Center in Massachusetts, said. To ensure that 90% of uniforms and workstations are suitable for new employees without modification. She said that unlike basketball, the length of military uniforms has not changed for some time. If you need to predict the height of human beings in the near future to design a device, Gordon said, in general, "you can use today's data and feel quite confident."
