　　A

　　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.

　　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　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. ”

　  1 A. And B. However C. Besides D. Though

　  2 A. rise B. rose C. raise D. raised

　  3 A. of B. with C. by D. from

　　4 A. difference B. matter C. thing D. meaning

　　5 A. successful B. gifted C. able D. rich

　　6 A. natural B. true C. certain D. possible

　  7 A. score B. intelligence C. skill D. interest

　　　 My favourite great book is The Adventure of Tom Sawyer by Mark Twain.Tom lives with his aunt Polly in a quiet street of St. Petersburg, Missouri.He's a lively and clever young boy, and he finds himself in many exciting adventures (冒险).He runs away with his two friends, Huck Finn and Joe, to an island in the middle of the Mississippi River for several days.With Huck he goes looking for treasure, with Becky he gets lost in a cave.And finally, they find a box of gold.

　　　 My favourite scene in the book is when everyone thinks Tom is dead.He decides to go to his own funeral.He hides and watches for a time, and then suddenly he appears.Everyone is surprised to see him but they're also pleased to see him alive.

　　　 Tom is the hero of the story, but there are other important characters.Huck is an outsider (外来者) and every?one is afraid of him.Becky is pretty with fair hair, Joe is Tom's best friend, and Injun Joe is the bad man of the story.

　　　 The theme of the story is about children growing up.It describes how strangers are seen in small towns of America.Finally, it talks about freedom, social rules and how people are punished (惩罚) for bad behaviour.

　　　 Why do I think The Adventure of Tom Sawyer is a great book? Mark Twain wrote the story in 1876, but it's still read and loved by people all over the world today.And although it's only a story, Twain wrote it in the everyday English of the southern states of America in the 19th century, so it sounds very real.Today it's thought to be one of the greatest books in American literature.Go on—read it!

　　I had my first job at the age of thirteen, when a friend of my mother’s who owned a book shop hired（雇佣） me for six hours a week to help her in the shop. I was very 　1　 　to earn my own pocket money and my parents 　2　 　interfered（干涉）with how I spent it, even when I was spending it foolishly. They believed that by earning money, spending it, and learning from the 　3　 , I would become more mature（成熟的） and responsible about how to handle work, relationships with others, and money.

　　Like many American parents, my parents also let me and my brothers do things over which they 　4 　　a great deal. When I was sixteen, for example, after I finished high school and before I entered university, I wanted to spend the summer months traveling around Europe. My mother was against the idea of my traveling alone at such a young age, but my father felt that it would be a great 　5　 　for me. In the end, my father won the argument（争论） on the 　6　 　that I limited（限定）my traveling to France, my mother’s home, where I had many uncles, aunts and cousins spread out through the country who could 　7　 　shelter（住处）and help if I needed them.

　　Three years later, my younger brother decided to 　8　 　a year off after his first year in university and travel through the United States and the Caribbean.

　　These kinds of experiences are probably rare（稀少的）for children in many countries but in the US they are fairly common. Most parents start 　11　 　their children at a young age to do small things by themselves. By the time they have finished high school, many American kids have already had part-time jobs, traveled around the US or other countries on their own, have selected the university they plan to attend and maybe even 　12　 　on their future career, and so on.
