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(三維) view of body organs(器官).
What is a CAT scan? CAT stands for Computerized Axial Tomography(層面X線照相術). 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

As I began to feel completely sick of the cold North American winter, spring break finally arrived! What made me even more excited was that we were going to Florida to enjoy the warm weather!
Just imagine wearing T-shirts or a swimsuit under the hot Florida sun!
Before the vacation started, we had a little episode(插曲) at the airport. The alarm sounded when my host mom and me were walking through the security check. We were taken away to have further checks, but when they finally told us that we could go, we felt relieved and amused. It was just because of the decorations(裝飾品) on my pants and the tinfoil(錫紙) around my host mom’s chewing gum! —Just as a reminder, no overly fashionable pants or tinfoil on a plane!
Of course, I had a lot of first experiences during this special vacation. Since eight of us were living in a house, we had to share bedrooms, I, fortuna
tely or unfortunately, h
ad to share a room with my 4-year-old host sister. She is tiny compared to me, but she took up about two thirds of the bed. Moreover, because I was not used to sleeping in the same room with others, I was afraid of waking her up and hardly slept at all.

It is not wise to rush out and buy new clothes.which will be worn for the first time at the interview．You’ll feel more at ease in a familiar dress．

Don’t take a seat until asked．Then sit comfortably．
Make eye contact when you are greeted and again if you shake hands．And during questioning,eye contact is a form of non-verbal greeting．

SEE a cell phone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting "print" on your computer.
You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays (噴) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (樹脂)and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair --- the smoother and finer the object will be.
This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now they cost only about £ 1,000, according to the BBC.
Taken out of the factory and introduced to more diverse and common uses, 3-D printing can create just about anything you can think of ---flutes (笛子), bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3-D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3-D printing becomes more commonplace, it may bring about certain problems --- such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun?
1.According to the article, in the future, the 3-D printing technology will ___.
A．enable people to make better purchases online
B．be applied as widely in our daily lives as computers
C．change the way we make many products
D．shorten the time it takes for people to get what they buy online
2.What was the big event happening in the 3-D printing industry last year?
A．The 3-D printing technology was taken out ofthe factory.
B．The 3-D printer became more affordable forconsumers.
C．The 3-D printer was used for medical treatmentfor the first time.
D．3-D printing technology began to be used invarious fields.
3.How is the last paragraph developed?
A．By analyzing a cause and an effect. B．By making comparisons.
C．By giving examples. D．By presenting research findings.
4.What is the best title of the passage?
A．Printing out everything B．Technology in the future
C．Online shopping disappearing D．Great demand for 3-D printers
