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).
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

American magician David Blaine left the glass box in which he had lived for 44 days without food on October 19. 2003. Hundreds of people came to watch the end of his starvation experiment, which has become one of London’s main tourist attractions.
Looking thinner and darker, 30 year-old Blaine was taken out of his box over the River Thames（泰晤士河）and immediately went to hospital. He was then slowly reintroduced to food, a process (过程)doctors say could be life threatening. He had been drinking only water since September 5.
A native of Brooklyn, New York, Blaine first became known as a street magician in the early 1990s. He soon found himself doing magic tricks in bars for the likes of American actor Leonardo DiCaprio and his super model friends.
Over the last decade Blaine has become famous with a combination of breathtaking magic and clever tricks aimed at getting a lot of attention.
In 1999, he was buried in a coffin (棺材) for one week and, in 2000, he spent 62 hours in a giant block of ice. Last year he stood on top of a 25-meter pillar(柱子) in the center of New York for 35 hours before jumping into a pile of boxes.
“I think a lot of people are unable to accept that they’re able to do what they can do,” he said. “They don’t realize we can survive. The human being is an amazing creation.”

Everyone has got two personalities—the one that is shown to the world and the other that is secret and real．You don't show your secret personality when you're awake because you can control your behaviour，but when you're asleep， your sleeping position shows the real you．In a normal night，of course，people frequently change their position．The important position is the one that you go to sleep in．

Tests administered（实施）to most elementary and high-school students in the United States exert（发挥）an unfavorable influence on science and math teaching， according to a new ＄1 million study performed for the National Science Foundation．And because schools with high minority enrollments（入学）generally place a greater reliance（相信）on scores from these tests， the study finds，there tends to be “a gap in instructional emphases between high and low minority classrooms that differs from our national concern for the quality of education．”
George F．Madaus and his colleagues at Boston College analyzed not only the six most widely used national standardized tests， but also the tests designed to accompany（go with）the four most commonly used science and math texts in fourth-grade，eighth-grade，and high-school classrooms．Though curriculum（teaching program）experts argue that schools should place greater emphasis on problem solving and reasoning， the new study shows that the tests focus on lower-level skills—primarily mechanical memorization of routine formulas（公式）．
Researchers surveyed more than 2，200 math and science instructors，interviewing in depth some 300 teachers and administrators．Especially in schools with high minority enrollments，teachers reported feeling pressured to help students perform well on these tests．Some states judge schools and some schools determine teacher assignments（工作安排）based on students' test scores．
“With so much worry，”Madaus says，“teachers feel forced to focus their instruction on drilling what the tests will measure—at the expense of the more valuable，higher-level skills．”

A．the tests don't affect teaching in most elementary and high schools

Happiness and sadness are states of being that define the way we view the world. It is often said that some people by nature have a sunny character. Now scientists may have discovered why.
Some people may be born for happiness, while others are genetically negative, scientists have suggested in a study published late February in a British journal.
Earlier research had already established that the gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter (神经传递素) serotonin (含于血液中的复合胺) works within the brain. Serotonin, a hormone (荷尔蒙), passes chemical messages between nerve cells. It has been closely linked to mood. Several anti-depressant (抗抑郁) drugs regulate serotonin levels. Scientists had also identified three variants (变体) of the gene. Two so-called "short" variants were linked to a higher risk of depression and suicide attempts. Unlike the two "short" variants, the "long" variant of 5-HTTLPR showed a clear dislike of negative images, such as fierce animals, and a clear liking for positive ones, such as flowers.
Researchers from the University of Essex in Britain, led by Elaine Fox, showed participants a series of images. The images were divided into three kinds: negative ones aimed at inspiring fear or stress such as a spider or person about to commit suicide, pleasant ones and neutral (中性的) ones. The participants who had the long variant of the 5-HTTLPR gene "showed a clear dislike of negative material alongside a careful attention for positive material," the researchers found. They paid close attention to the pretty pictures, and ignored the frightening ones. On the other hand, the short variant groups had the opposite reaction.
In January, the Australian government organized "happiness workshops", teaching government staff how to be happy. The department that held the "happiness workshops" said unhappy staff weren't productive staff. Australian political opposition parties have argued that the "happiness workshops" are probably a waste of money and couldn't increase productivity as intended. However, whether the workshop will have a happy or disappointing result, we will have to wait and see.
