Question

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（挑戰(zhàn)）this idea. According to an article last October on the Journal Nature, scientists are beginning to think that our IQ is not a constant（不變的）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（掃描）. They found that the IQ changes matched changes in the structure（結(jié)構(gòu)）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. ”
