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 day before the surgery I was off school, and my mom planned the best day of my life, everything I loved at seven and everything that would put a smile on my face.

The panda is one of the animals most in danger. Three are about 1,000 pandas living in nature reserves today. Zoos and research centers look after about 160 pandas. Scientists are studying how they live and more baby pandas are born in the zoos.
Pandas live in the forests and mountains of Southern China. They mainly live on bamboo, and each pandas needs to eat a lot of bamboo every day. The area of bamboo is becoming smaller for many different reasons, so pandas have less and less land to live on. Pandas don’t have many babies, and baby panda often dies. The situation is becoming very serious.
Our government is working hard to save pandas. There are more than 30 nature reserves to protect pandas but these are not enough. The government has made a new plan to help pandas. The nature reserves will be bigger and the bamboo will grow better. Then the pandas will have enough food and enough places to live in. Pandas born in the zoos may go back to live in the nature reserves.
Most people love pandas. The panda is one of the best-known animals in the world. It is the symbol for the World Wide Fund for Nature. The WWF works to protect all animals in danger, so the panda has become the symbol of all animals in danger. There is still a long way to save the panda. Think of other animals in danger.
