What can you do if you "lose" the data(数据)from your disks(硬盘)? To find an expert, who can recover the lost information for you, is probably the easiest solution. Jack Olson is one of these experts. Jack and a few of his friends set up a company called "Jack's Disk Doctor Service". They work from home and give all the money they earn to charity(慈善团体). The fees are always the same, no matter how precious the data on the disk is. Some people, however, are so grateful that they send extra money to Jack or to the charities his company supports. One oil company offered him $2,000 for his help and an architect even sent him a blank check.

It would be difficult to put a value on the things rescued by the Disk Doctor. There have been disks which contain medical research, television scripts, manuscripts of whole books, a lawyer's papers for a court case, and even Margaret Thatcher's travel plan for a visit to eastern Europe. For this last case, Jack had to go in person to Thatcher's office "for security reasons"!

Disks are usually sent to the Disk Doctor by post, but sometimes people are in such a hurry that they cannot wait for the mail to come. For example, some radio scripts had to be rushed by taxi to Jack's house because they were needed for broadcasting the next day. When the material has been recovered, the disk is returned to the sender with a diagnosis(诊断)and a prescription for avoiding the problem in the future. One grateful client(顾客), and author, put a "thank you" to Jack in the front of his book, "Jack saved me from a heart attack," he wrote. "But," says Jack, "most people don't take any notice of the doctor's advice!"

Why did the architect send Jack a blank check?

A. The architect did not have any money.

B. The architect did it for security reasons.

C. The architect always followed the doctor's advice.

D. The architect thought Jack's service was priceless.

What does the underlined word "rescued" mean?

A. Recovered.       B. Prescribed.      C. Examined.       D. Lost.

Which of the following statements is NOT true?

A. Jack's Disk Doctor Service has only one standard fee.

B. Jack and his company have made a fortune from their service.

C. Margaret Thatcher is a very important person.

D. Jack's clients are from all walks of life.
