　　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.

　1 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.

　　Scientists found big changes in the IQ scores between 2008 and 2004. Some　2and some fell 3 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 　4 ,” said Professor Cathy Price, who led the research. He said it could mean the difference between an average and a 　5 person. The team has not found a clear cause for these changes. However, they say it is 　6 that education plays a role in changing IQ. “Here we have shown that children’s 　7 is likely to be still developing, ” says Price. “We have to be careful not to write off 　8 performers at an early stage. In fact, their IQ may improve in a few more years. ”

The English language is different from any  36  language. Yet English words do not  37  the same. It is always  38 . People need new words  39  new inventions and new ideas. Different words come into use or older words are used  40 a new way.

English can 41 by borrowing words from other languages. The word “tomato” was borrowed from Mexico, the word “coffee” came from Turkey, and “tea” from  42  and so on. Now new space and science words  43  from other countries, too. New words are also made by adding two words  44 . The words “strawberry”, “postman” and “blackboard” are made up of two parts.

Sometimes, new words are  45  forms of old words. The word “photo” was made from “photograph” by cutting off the  46  of the long word. The word “plane” was made by cutting off the  47  part of “airplane”. 48 “smog” was made by using only the first two letters of “smoke” and cutting off the front part of “fog”. And products can become new words. Our “sandwich” was named after  49  named Sandwich, and “jelly(果冻)” was a name made up by the company that  50 made this product.
