One American university used a robot as a teacher to help students with their problems. And none of the students knew that was a robot in the beginning!

Jill Watson, an IBM-designed robot, has been helping graduate students at Georgia Institute of Technology (美國(guó)佐治亞理工大學(xué)) solve problems with their design projects. When answering their questions, Jill seems to be an excellent teacher. She can give wonderful answers quickly. She sounds natural and usually says good words. After 5 months, the students were told that their "teacher" was a robot, and many were shocked.

Now many students like to ask questions on their school's website. It usually takes teachers too much time to answer them. So the university had such an idea of making Jill Watson. It's a faster way to help the students with their problems.

Jill can quickly find possible answers to the questions in her own computer and make sure they are all right. After that, she tells the students in an electronic voice that sounds like a famous actress. She was trained by Georgia Tech researchers before being thrown into the mix with nine other teachers.

Robert Fredy was general manager of a large hotel in Ashbury Park, New Jersey. One cold day two years ago when he stopped his car at a traffic light, Stephen Pearman, an out-of-work taxi and truck driver, walked up to Fredy’s car hoping to earn some change by washing his windshield（擋風(fēng)玻璃）. Like many motorists who try to keep the beggars off, Fredy turned on the wipers to show he wasn’t interested. Pearman put his head close to the window. “Come on, mister. Give me chance. I need job”, he said. Something in Stephen Pearman’s voice moved Robert Fredy. In the seconds before traffic started moving again, Fredy handed Pearman a business card and told him to call if he was serious.

“My friends told me he was just pulling my leg,” said Pearman. “But I said, ‘No, he’s a businessman. I need to give it shot. ’”

Two days later, 29-year-old Pearman appeared in the manager’s office of the big hotel. Fredy gave him a job and lent him pocket money while training him.

Today, Pearman works full- time setting up the hotel’s dining halls for business meetings. In the past two years, he has found a flat, married and repaid Fredy’s loans（貸款）

“Mr Fredy gave me a second chance,” says Pearman. “And I took advantage of it. I could have just come here a while and left. But there is no future washing wind- shields. ”

Fredy always keeps away from the street people. “But. Pearman seemed so honest and open, asking for a chance rather than just money, Fredy says. “I don’t hand my business card to just anybody. But I’m glad I did in this case. ”
