How can you find out what is going on inside a person' s body without opening the patient up? Regular X-rays can show a lot. CAT scans can show even more. They can give three-dimensional(三维) view of body organs(器官).
What is a CAT scan? CAT stands for Computerized Axial Tomography(层面X线照相术). 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 examine diseases and injuries within the body. X-rays can find foreign objects inside the body or to take pictures of some organs inside if special things as dyes or special liquids are added to the organs to be X-rayed.
A CAT scanner, however, uses a beam(光束) of X-rays to give a cross-sectional view of a particular part of the body. A fine beam of X-rays is scanned across the body and circled around the patient from many different angles(角度). A computer analyzes(分析) the information from each angle and produces a clear cross-sectional picture on the screen. This picture is then photographed for later use. Several cross-sections, taken one after another, can give a clear "photo" of the entire body or of any body organs. The newest CAT scanners can even give a clear picture of active, moving organs just as a fast-action camera can "stop the action" giving clear pictures of what appear only mistily(模糊) to the eye. And because of the 360 - degree pictures, CAT scans show 3-dimensional views of organs in a manner that was once only seen during surgery or autopsy (examining a dead body).
69. According to the first two paragraphs, doctors can see the inside of a patient's body by ______.
A. giving the patient an operation
B. checking body organs
C. getting a 360-degree picture of a small area of a patient's body
D. examining the CAT
From the last paragraph, we can infer that ______.

A.the newest pictures become more misty
B.many pictures can be taken at the same time
C.the information about the scanned patient is not highly valued
D.some pictures of the scanned parts of the body are developed for further examinations in the future

The best title of this passage might be ______.

A.Modern X-ray B.Three-dimensional View
C.Fast - moving Camera D.CAT Scan

Jonathan James looks like just another kid about to graduate from high school. But this 19-year-old Swede is anything but ordinary, from the computer in his parents’ home he helps the US Federal Bureau of Investigation(FBI) find out the world’s most wanted cyber criminals(网络犯罪分子).
Jonathan first made headlines when he and another Swede, Fredrik Bjoerck, found out the maker of the “Melissa” virus(病毒) in March 1999. He came to the aid of the FBI again on May 7, finding out the suspected(嫌疑的) sender of the dangerous “I LOVE YOU” virus. The suspect was caught in Manila on May 8.
Jonathan’s special skills are in hot demand as officials around the world express alarm at the “virtual” crimewave. In between studying for final exams, hanging out with friends and refereeing his younger brother’s football matches, the quiet, gentle teenager also gives lessons on e-security(电子安全) to large companies. He reads a lot and exchanges information with other computer experts to know much about the latest tricks of the hacker (黑客) trade.
Many companies have already tried to employ him, but he is not interested at the moment. Instead, he plans to begin law school in the autumn at Sweden’s Uppsala University and start up his own e-security company.
Although he works with the FBI now, his family insists he’s just “a regular kid”. “Jonathan is a great kid, he has his friends and he does a lot more than just play with the computer,” his little sister Tessa said, adding that he helps the FBI because “he likes to help”, not because he’s looking for fame and recognition.
When the world was hit by the “Love Bug” virus, Jonathan was too busy preparing a speech on e-security to look into the problem. “Finally on May 7, I had some free time, so I began looking.” Within a few hours, he had found the suspect and e-mailed his method and results to the FBI. He said his work on the “Melissa” virus, which took three weeks to solve, was a big help in finding the suspect so quickly.
“This time I knew exactly where to start, I knew what to disregard and what to look at.”
The passage mainly wants to tell us that______.

Jeanne Calment, a French woman, became a record breaker on 17 October of 1995, when at the age of 120 years and 238 days, she became the longest-lived human being on record. A Japanese man died in 1986 at the age of 120 years and 237 days.
Jeanne Calment lives in a small old people’s home in the south of France; her husband, her only child and her grandson have all died. She is nearly blind and deaf and is always in a wheelchair, but her doctor describes her as being more like a 90-year-old in good health than someone of 120. She still has a lively sense of humor. When asked on her 120th birthday what she expected of the future, she replied: A very short one. She also remarked that she thought the good Lord had forgotten all about her.
So what is the key to a long life? According to some doctors, diet, exercise and no smoking are the three important factors. Jeanne Calment has followed two of the tips(窍门). She has always eaten a healthy diet, and she used to do exercises every day until she broke her leg at the age of 115. However, until recently she drank two glassed of strong red wine a day, and she does smoke (now only a little). Besides, Jeanne Calment might have got very good genes(基因) from her parents. Her father lived to the age of 94 and her mother to 86.
A local lawyer bought her house when she was 80 under an agreement that he would pay her some money every year until her death. It must have seemed a good move at the time, but so far the lawyer has paid her at least three times the value of the house. Every year on her birthday Jeanne Calment sends him a card saying:
Sorry, I’m still alive!

Which of the following could best replace the word “move” in the fourth paragraph?

A.deal B.trick C.march D.sport

Why does Jeanne Calment say “Sorry, I’m still alive” to the local lawyer every year on her birthday?

A.Because she had an agreement at 80 with the lawyer which was to her advantage.
B.Because she has asked the lawyer to pay her more rent than they first agreed.
C.Because the lawyer has paid her much more money than the value of the house.

If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.
