How can you find out what is going on inside a person’s body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.
What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.
Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
A CAT scanner, however, uses a group of X rays to give a cross-sectional（横截面）view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “stop the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays.
CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.

Today, we talk to an up-and-coming (有前途的) erhu player, Lee Hang, from Hong Kong. He’ll play with the Hong Kong Orchestra (管弦乐队) next Sunday in a special concert by young Chinese musicians.
Interviewer: Thank you for talking to us, Lee. You must be very excited.
Lee: Yes, I am. This is the first time that I’ve played with such a famous orchestra and in front of so many people. They’re expecting about 4,000 people.
Interviewer: Does that scare you?
Lee: To be honest, yes. I haven’t slept much in the last few days. But my teacher told me I wouldn’t take it seriously enough if I wasn’t scared. That helped a lot.
Interviewer: Tell me about why you started playing the erhu.
Lee: My parents took me to piano and violin lessons. I quite liked them but they had to force me to go sometimes. One night, I saw a documentary about Yo Yo Ma, the famous Chinese American cello(大提琴) player. He talked about his love of Chinese instruments and we should follow our interests. I always enjoyed listening to Chinese instruments like the erhu and guzheng. That inspired me to learn the erhu. My parents were glad that I was playing something I actually liked.
Interviewer: What do your friends think of you playing a Chinese instrument?
Lee: Well, a lot of my classmates think playing things like the erhu isn’t cool. I don’t care. It makes me happy. I got a letter from Yo Yo, saying how much he admired me and that he’d like to meet me next time when he’s in Hong Kong. They thought that was pretty cool!
Interviewer: And what does the future hold for you?
Lee: I’d like to study music in a university in China then hopefully play in orchestras. My ambition is to bring the beautiful sound of the erhu to all the corners of the world.
Interviewer: Well, if anyone can, it’s you. Thanks for talking to me, Lee. Good luck.
Lee: Thanks.

Parents need to be good role models to help their children make sensible financial decisions, according to Adam Hancock and hs team, from East Caronlina University in the US. Their work highlights that parents who argue about finances contribute to increasing credit card debt among their children during their students years. Their work is published online in Springer's Journal of Family and Economic Issues.
Credit card debt among college students has been a growing concern for researchers and policymakers over the last decade. In addition, there is growing concern among educators that more students are dropping out of school, not because of academic failure, but because of financial reasons, and credit card especially. Hancock and colleagues' study is the first to examine how parental interactions, and financial knowledge and attitudes may have a cumulative effect（累积效应）on the number of credit cards students own and their level of credit card debt.
The researchers analyzed data for 420 undergraduate students from seven different American universities, who took part in the College Student Financial Literacy Survey. According to the online survey, nearly two-thirds of students had a credit card, and nearly a third had more than one. Those students who reported that their parents argued about finances were more likely to have more than two cards than the students whose parents who did not argue about finances.
In terms of debt, those students who had two or more credit cards were nearly three times more likely to report having credit card debt over ＄500.
The researchers conclude, "It is clear that the influence of parents cannot be neglected. Researchers, educators and policymakers should work in finding effective ways to increase the positive financial behaviors fo college students. We need to help students learn financial skills and establish healthy financial attitudes at earlier ages to prevent poor financial habits from taking root."
31. In Adam Hancock's research, student's credit card debt is related to their _________.
A.knowledge B.concerns C.school D.parents
32. When college students have credit card debt, they may ________.
A.quit school B.fail in their exams
C.study financial knowledge D.have more credit cards
33. What can we infer from Paragraph 3?
A. More than 400 students i a university took the survey.
B. The survey was conducted with the paper questionnaire.
C. Nearly all the students in this survey have credit cards.
D. Students have fewer cards if their parents argue more.
34. If you have two or more credit cards, you are more likely to ________.
A.get wealthy B.have argument C.buy more things D.become in debt
35. As a student, what can yo learn from the passage?
A. We need to turn to our parents when we have credit card debt.
B. We should build correct financial attitudes when we are young.
C. We shouldn't have credit cards so that we can avoid argument.
D. We can have more credit cards to make life more comfortable.
