    Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into an object. This is now possible with the help of 3D printers. Such machines were once used just by universities and big companies, but now, stores with 3D printing services are appearing around the United States.
    Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The Jaycoxs offer 3D printing classes and services for anyone who is interested.
    “I think 3D printing is going to be huge. It’s going to have a huge influence on society as a whole.” says KiChong Tran, one of the students in a recent class. He plans to open a 3D printing business in Cambodia (柬埔寨).
    3D printing services are coming into American people’s life. The UPS Store is a nationwide retailer (零售商) that provides copying and other services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke Jones owns one of the stores in San Diego.
    “The demand has been amazing. There has been a lot of interest from people. It’s been much more than I would have imagined.”
    The UPS Store plans to add 3D printers in three more stores.
    For $11, someone used a 3D printer to produce two small plastic parts as part of a knuckle (指节) for a hand. He works for the company which is testing finger prosthetics (假肢). He says the same–day or next-day printing services will speed up testing of parts and get them to patients faster.
    Staples, an American store, is selling 3D printers on its website for as low as about $1,300. As with any technology - experts expect the printing speed to increase and the price to go down.
    Bryan Jaycox requires $15 an hour to print an object. He also sets the price depending on the size of the object and up to $50 an hour for design and labor services.
    Mr Jaycox thinks that within five years, 3D printing technology could become more user friendly. But KiChong Tran says even today’s technology can make a difference in a developing country like Cambodia.
    “With 3D printing you can give them tools, so they are responsible more for their own development and they learn skills beyond just like learning English and becoming a tour guide or something like that. You can actually create things that give value to the world.”
    He says it’s not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality.
    小题1:What can 3D printers do according to the passage?
    A．Come up with an idea.
    B．Draw on a piece of paper.
    C．Help users to spend less money.
    D．Turn an idea into a physical object.

    A．Make users’ life better.
    B．Make friends with users.
    C．Make 3D printers easier to use.
    D．Use 3D printers to make money.
    小题3:What can we infer from the passage?
    A．3D printing is becoming popular in the world.
    B．There is no 3D printing business in Cambodia.
    C．The UPS Store is the biggest 3D printing company.

    There is a famous saying from the French politician J.A. Brillat-Savarin that goes: “Tell me what kind of food you eat, and I will tell you what kind of man you are.” It can be easy to not really think about what you eat. For example, whenever you go into a supermarket to buy a drink, it is all too easy to pick up an ice cream or a piece of chocolate as well. You might not even really want them, but sometimes their bright, nice packaging(包装) can be too hard to refuse.
    So, in our special food magazine we will show you why you should really pay more attention to what you eat! Food not only influences our health but also our beliefs, customs and personalities. 
    The first article will look at the way fast food is leading to obesity (肥胖). The famous cook, Jamie Oliver, has made it his purpose to introduce ideas about healthy eating. In a speech, Jamie Oliver told the world that during the 18 minutes that he gave his speech, four Americans would die because of the food that they ate! Obesity is also a growing problem in China. As China Daily reported in February, the number of obese people under the age of 18 in China has reached 120 million.
    Jamie has worked for 10 years to try and fight this problem. Learning about food is important not just because of health problems but also because many people still don’t have enough food today. And we know as the improvement of science sometimes we have to face genetically modified (转基因) food. Don’t worry – we’ll make you know more about all these topics in our special article! 
    We’ll also tell you something interesting about food. For example, do you know what the largest food on the menu is all over the world? It’s the roasted camel and it has been served for several hundred years, often stuffed (填满) with chicken, lamb, egg, fish and rice! 
    Hopefully by the time you finish reading this edition(版本), you’ll pay more attention to the food that you eat. As Oliver says, food is something that can help us enjoy our life. It is important that we love it!
    小题1:Where is J.A. Brillat-Savarin from?
    A. America.     B. England.      C. France.       D. Australia.
    小题2:Food can influence us in many ways except our ___________.
    A．healthB．beliefsC．customsD．dreams
    小题3:Someone is too fat , maybe because he eats too much ______.

    		Question: First trip to the USA
    For my new job, I will travel to the United States next month and meet my American boss. This will be my first trip there. I’m worried about correct business behavior and manners. My boss invited me to his home for dinner. Do you have any advice?

    		Re: First trip to the USA
    It’s a good idea to bring a small gift or something from your country. Don’t be surprised if your boss opens the gift right away. In the USA, people often open a gift when they receive it. In Korea, that is not polite, but it’s common in the USA.

    Americans use their hands to eat some kinds of food, such as pizza and fried chicken. Watch your American hosts, and do what they do.

    In Korea and Japan, it’s the custom to remove your shoes before entering a house. In the United States, you usually don’t take your shoes off. Once I was travelling in Japan and entered a house with my shoes on by mistake. Oops!

    		Re: First trip to the USA
    Many Americans are very informal（非正式的）at home. One time I went to an American business partner’s home for dinner, I was surprised that everyone stood and talked in the kitchen while the husband and wife were cooking dinner. Besides, unlike in Korea, everyone took part in the dinner table conversation, even the man’s wife and children.

    		Re: First trip to the USA
    I agree with Lee. You probably won’t speak about business during dinner, so my advice is to know some   topics of conversation. For example, you can talk about travel, food, music, or sports. But you’d better not question about age.

    Many people go to school for an education. They learn languages, history, politics, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living.
    School education is very important and useful. Yet, no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.
    It is always more important to know how to study by oneself than to memorize some facts or a formula（公式）. It is actually quite easy to learn a certain fact in history or a formula in math. But it is very difficult to use a formula in working out a math problem.
    Great scientists before us didn’t get everything from school. Their teachers only showed them the way. Edison didn’t even finish primary school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they knew how to study. They read books that were not taught at school. They would ask many questions as they read. They did thousands of experiments. They worked hard all their lives, wasting not a single moment. Above all, they knew how to use their brain.
    小题1: People go to school to _________.
    A．learn several subjectsB．make a living
    C．get an educationD．learn from teachers
    小题2: According to the passage, the most important thing a teacher should do is _________.
    A．to teacher his students everything he knows
    B．to teach the students how to think
    C．to know everything they want to know
    D．to teach the students how to work out a math problem
    小题3:To work out a math problem, you need to know _________.
    A．only a certain formulaB．a certain fact
    C．some factsD．the way to solve it
    小题4:Why were many scientists so successful?
    A．They received good education.B．They were very clever.
    C．They knew how to learn.D．They learned lots of facts and formulas.
    小题5: How did great scientists study?
    A．They read a lot of books and asked many questions while reading.
    B．They did thousands of experiments.
    C．They always worked hard and never wasted time.
