Teachers and textbooks beware―your future could be under threat from a quickly developing and very smart technology．

University of California researchers led by Jacob White hill recently programmed teaching robots to react to facial expression．White hill's achievement marked a major step forward in the way people could one day learn by establishing facial expression recognition in robot teachers.

The teaching robots or，Intelligent Tutoring Systems（ITS）are computer systems that provide personalized instruction and feedback to students without human intervention．The facial expression recognition allows a computer to react according to expressions a user makes.

He said that the system was an important development in improving learning systems. “Classical I T S typically have a somewhat rigid architecture of ‘first I ask a question; then I wait for a response; then I talk some more；then 1 wait for another response.’ Facial expression recognition，l believe，will allow the feedback from student to teacher to happen while the robot teacher is talking．”White hill said．

Experts agree the latest developments in ITS open new possibilities for how people could learn．University of Memphis researcher, Dr Andrew Olney，who recently received a US $1.3 million grant to develop an ITS，said the key to future learning will be enabling interactive（交互的），one-on-one instruction．

“The technology can benefit these more advanced learning scenarios（方案），”he said．

Although robot teachers of varying abilities have existed for more than 30 years，ITS developments such as White hill's and Olney's are pushing beliefs that robots could soon be as effective as―if not more effective than human teachers．

“The ITS which have been developed are already better teachers than people who have no experience�！監(jiān)lney said．

科目：高中英語 來源：2011-2012學年河南省鎮(zhèn)平一高高三下學期第三次周考英語試題 題型：閱讀理解

Anthony was sad. He was, as he put it, “not very bright” and couldn’t win the attention of his very wealthy parents, who preferred his “clever” older brother. At age 8, Anthony was sent away to a boarding school in his native England, even though he screamed and pleaded with（懇求）his parents year after year not to send

him. “The thought was ,it would be good for me,” he recalled.

It was not. Anthony did badly in his studies, had few friends and was bullied for five years. “My teachers couldn’t have had a lower opinion of me,” he said. “I wasn’t even smart enough to rebel. The one thing I remember from the very earliest age was the desire to write. When I was 10 years old, I remember asking my parents to get me a typewriter for my birthday because I wanted to be a writer.”

Now, at 55, Anthony is one of the world’s most successful children’s book authors. His Alex Rider series has sold more than 5 million copies，and the eighth book featuring the young spy, Crocodile Tears, has come out.

The Alex Rider books tell the adventures of 14-year-old Alex Rider, an agent for the British intelligence agency M16.

Anthony says he doesn’t try to write for kids; it just comes out that way.“ I have a feeling that it has something to do with purity and simplicity. I give as little information as is necessary to describe the room, the character in the room, and get on with the action,” he said.

The style has also made Anthony a successful writer of television shows for adults in Britain because, he says, writing books for kids is a lot like writing television for grown-ups: In both cases, it’s all about entertaining people with a good story.

Now, Anthony couldn’t be happier with his life. He sums up his success:“…you can be anything you want to be if you just believe in yourself. I do believe it completely.”

1.Which of the following is true of Anthony?

A. He was the beloved child of his family.  

B. Although he is successful, he isn’t very happy.

C. He places more emphasis on the characters’ behavior in his stories.             

D. Studying in a boarding school proved a good choice for him.

2.At boarding school , Anthony’s teachers_____________.

A. often criticized him.                              B. showed great concern for him.

C. encouraged him to be a writer.                D. thought little of his ability.

3.What would be the best title for the passage?

A. Anthony’s popular books—Alex Rider series

B. Alex Rider, a popular character

C. Anthony, a successful children’s book author  

D. Special writing style

4.What advice does Anthony give to readers?

A. Confidence is the key to success.     B. Hardship teaches valuable lessons.

C. Internet is the best teacher.                     D. Failure is the mother of success.
