To what degree can a computer achieve intelligence? The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet.

If you ran into Smarter Child online, you would be surprised at this kid’s huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season.

He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get strange answers. A question about Smarter Child’s age returns. “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives，you get, “In a clean room in a high-tech building in California.”

Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www.intellicast.com.

Some scientists believe that by joining the many systems of the Internet, an artificial being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears can be born. However, if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I. (Artificial Intelligence), he must overcome two problems.

The first is that computers find it difficult to read web pages because the files are labeled in different ways. That’s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself.

Another problem is that while Smarter Child can process information more exactly and faster than any human, he lacks common sense—a basic grounding of knowledge that is obvious to any young child.

From the text we can infer that www.intellicast.com is a website          .

A. which is specially designed to help Smarter Child

B. where we people can find Smarter Child

C. where weather forecasts are made

D. which is about artificial intelligence

It is probably most difficult for Smarter Child to         .

A. tell us how to spell a difficult word     

B. tell us how the American government is run

C. provide us with a famous poem by Shakespeare

D. learn the ability to tell right behaviors from wrong ones

Which of the following is TRUE according to the text?

A. Smart Child has his own memory bank big enough for all kinds of information.

B. A.I. (Artificial Intelligence) is probably the name of a film about a boy-computer.

C. Smart Child can recognize different files and find information needed on his own.

D. We have similar product now which has the knowledge of Einstein, Nixon and Spears.

Which of the following is the best title for the passage?

A. A New Web Child            B. Smarter Child

C. The Future of Internet             D. Intelligence Development
