Computer programmer David Jones earns ¥35,000 a year designing new computer games, yet he cannot find a bank ready to let him have a credit card (信用卡). Instead, he has been told to wait another two years, until he is 18. The 16-year-old works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David’s firm releases (推出) two new games for the fast throwing computer market each month.

But David’s biggest headache is what to do with his money. Even though he earns a lot, he cannot drive a car, take out a mortgage (抵押贷款), or get credit cards. David got his job with the Liverpool-based company four months ago, a year after leaving school with six O-levels and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs,” he said. David spends some of his money on records and clothes, and gives his mother 50 pounds a week. But most of his spare time is spent working.

“Unfortunately, computing was not part of our studies at school,” he said. “But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.” David added: “I would like to earn a million and I suppose early retirement (退休) is a possibility. You never know when the market might disappear.”

60. In what way is David different from people of his age?

A. He often goes out with friends.B. He lives with his mother.

C. He has a handsome income. D. He graduated with six O-levels.
