第6题
At 13 years old, Keith Peiris is the world's youngest CEO(Chief Executive Officer). But he says that there is nothing different about him compared to other children his age.
Keith launched(开办)a website for his own company at the age of 10. While other children were receiving awards for their achievements, Peiris was giving scholarships from Cyberteks Design, his own company, to pupils at his school.
Though he's just a teenager, he is already experiencing the pains of adult life.
Peiris is about 1.5 metres tall with big brown eyes and curly (卷曲的)jet-black hair. "His big eyes show his intelligence. They show his wisdom," said Christine St Pierre, a journalist from the Canadian Broadcasting Corporation.
When he was asked for an exclusive (独家的)interview, Peiris looked at his watch and said, "20 minutes, 30 minutes at most, OK？"
He has the air of a real businessman who treasures every minute of his time.
Cyberteks Design mainly serves North America. But since Peiris visited China, he said he would try to find a way to cater for(迎合) China's Shanghai market as well.
"China is growing and in the next 10 to 20 years it will be among the top countries for business. Now China's become a member of the WTO, Shanghai will have more business opportunities ," said the young businessman.
"At the moment it is hard to compete with local companies in Shanghai because of the cost, especially of hardware."
"At first, my age will be the largest issue, but in the end that won't be important," he added, "Once I get more and more clients(客户),we will build a reputation(信誉) and people will take me more seriously."
Peiris answers questions quickly and is very articulate (表达能力强的)for his age. He said he had come to know Shanghai pretty well through TV programmes shown on CNN before his trip.
He added, "When I was about five, my father gave me my own computer and started teaching me a few things about how to use it. I have not seen any parents do that for their children."
Keith Peiris is now ______.
A．a student
B．CEO of a company
C．doing business in Shanghai
D．both A and B
