题目列表(包括答案和解析)
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.

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
It's not about how much money you make, and it's not about who your daddy is. We're talking about being attractive in general, whether it's on a job interview or just gaining the respect of your colleagues . . .
Ask lots of questions
If you come across as a know-it-all (even if you really do know it all!), it really pushes people away. Rather, asking lots and lots of questions makes people feel like you care, you can be trusted.
Great body language
Your body language says a lot about you - it says whether you have confidence, or simply if you really care. Talking physically, it is one of the most important physical characteristics you need!
Stay busy
Always have something to do. Have you ever seen someone just sitting around, doing nothing? How unattractive. Always be busy with something, even if for some reason you have to make something up.
Show your pearly whites (or just smile)
Smile more, no matter how ugly your teeth are. I'm not kidding about this one. It's not all about the teeth. If you are smiling genuinely, you can draw everyone for 100 meters around to you.
Wear what fits
Wear clothing that fits you. For women, wearing tight pants or shirts is not attractive. Things that just fit you and your shape are the best but not tight. Wear things that fit you nicely, please . . . And for goodness sake, both sexes, stay away from logos and printed shirts! Most people you may ask do not find this attractive. Stop being some company's billboard(广告牌).
Be interested in other man
Be interested in the other person. Don't talk about. If you are truly interested in the person, it will come across. And if you want to talk about yourself, you'll find that putting the other person first actually opens him up to return the favor and ask you questions. See how fun this is?
1.It is your ________ that makes you attractive.
A. your family background
B. fashionable tight clothes
C. your appearance and your wealth
D. proper body language and behavior
2.According to the author, if you ________, you can be trusted.
A. always smile and show your pearly teeth
B. keep asking lots of questions
C. are interested in other people’s personal affairs
D. always wear clothes that fit you
3.The purpose of staying busy is to ________.
A. gain praises from your boss and colleagues
B. look attractive among people
C. show that you are interested in your job
D. get promoted in your company
4.If you are going to a job interview, which of the following is a proper behavior?
A. Wearing a shirt with printed logos
B. Keeping talking about your own experiences and talents
C. Staying still, not making any body language
D. Smiling truly toward the people you will meet
