It is often difficult for a man to be quite sure what tax he ought to pay to the govemment be-

cause it depends on so many different things: whether the man is married; how many children he

has; whether he supports any relations; how much he earns; how much interest he receives; how

much he has spent on his house during the year, and so on and so forth. All this makes it difficult to decide exactly how much the tax is.

There was a certain artist who was always very careful to pay the proper amount.

One year, after posting his check as usual, he began to wonder if he had paid enough, and af ter a lot of work, with a pencil and paper, he decided that he had not. He believed that he owed the government something.

He was just writing another check to send to the tax-collector when the postman dropped a let ter into the box at the front door. Opening it, the artist was surprised to find inside it a check for five pounds from the tax-collector. The official explained that too much had been paid, and that therefore the difference was now returned to the taxpayer.

65. It is mentioned in the passage that one has to pay tax according to________

[ A] how much education one has received

[ B ] whether one is single or married

[ C] how old one' s children are

[ D] where one lives

听力原文： That's how Shown O'Neill looks back on the heart attack he experienced shortly after his 31st birthday.

"I thought I was in perfect health," Shown says. "I was never sick. I woke up feeling good every morning."

Then on that fateful day in April 2002, he received a giant eye opener. He was working in his yard in Hixson and started having pain in his chest and arms. "I wag pretty sure what it was, but I couldn't believe it could be happening to roe." The good news is that because Shawn recognized the symptoms and went immediately to Memorial Noah Park Hospital, he received the treatment he needed and the damage to his heart muscle was minimal.

"Advances in medicine make it possible for us to stop many heart attacks and keep people alive if they get to the hospital in time," says Dr: Kinsman Wright, medical director of Cardiac Services at Memorial. "We have technology to pinpoint blockage in the cardiac, arteries and several options to open the vessels. And lifestyle. changes and medications are helping people reduce their risk factors."

But Dr. Wright doesn't see any decrease in heart disease. "With people living longer, we're seeing different types of heart disease. We need to keep studying and fighting it on all fronts."
