IQ(intelligence quotient智商)is a score that shows a person’s level of intelligence.

    People used to believe that some people are born with a high IQ and some aren’t.

      32  , a study by scientist at University College London has challenged(挑战)this idea. According to an article last October on the Journal Nature, scientists are beginning to think that our IQ is not a constant(不变的)score.

    The scientists tested 33 healthy young people in 2004 between the ages of 12 and 16. Then they did tests again four years later, when the same people were between 16 and 20.

    Scientists found big changes in the IQ scores between 2008 and 2004. Some  33  and some fell  34  as many as 21 points.

    To test whether these scores were meaningful, the scientists compared them with results from brain scans(扫描). They found that the IQ changes matched changes in the structure(结构)of the subjects’ brains. “A change in 20 points is a huge  35  ,” said Professor Cathy Price, who led the research. He said it could mean the difference between an average and a  36  person. The team has not found a clear cause for these changes. However, they say it is  37  that education plays a role in changing IQ.

    “Here we have shown that children’s  38  is likely to be still developing, ” says Price. “We have to be careful not to write off  39  performers at an early stage. In fact, their IQ may improve in a few more years. ”

The Mayan(玛雅的)Indians lived in Mexico for thousands of years before the Spanish arrived in the 1500s. The Mayan achievements were many. They had farms, beautiful palaces, and cities with many buildings. The Mayan people knew a lot about nature and the world around them. This knowledge helped them to live a better life than most people of that time, because they could use it to make their lives more comfortable and rewarding(值得的). Knowledge about tools and farming, for example, made their work easier and more productive.

    The Maya believed in many gods, including rain gods, sun gods, and corn gods. The people built large temples to honor the Mayan gods. Skillful workers built cities around these temples. It was difficult for them to build these cities, because they had no horses to carry the heavy stone they used to build with. Workers had to carry all of the building materials themselves. Today, many of these ancient Mayan cities and temples are still standing.

    Although the cities that the Maya built were beautiful, and the people worked hard to build them, very few of the people lived in them. Usually, only the priests(牧师)lived in the cities.

    The other people lived in small villages in the forests. Their houses were much simpler than the elaborate buildings in the cities. They lived in small huts(小屋)with no windows. The walls were made of poles covered with dried mud, and the roof was made of grass or leaves. Most Maya lived a simple life close to nature.

    The Mayan priests studied the Sun, the Moon, stars, and planets. They made a calendar from what they learned. The year was divided into 18 months of 20 days each with five days left over. The Mayan calendar was far more exact than the European calendars of the time.

    Around the year 800, the Maya left their villages and beautiful cities, never to return. No one knows why this happened. They may have died from some disease. They may have left because the soil could no longer grow crops. Archaeologists(考古学家)are still trying to find the lost secrets of the Maya.
