Imagine having an idea,drawing it on paper,bringing it to a store and seeing it turned into a physical 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 store is filled with tools like a laser cutter,an industrial sewing machine and 3D printers.The Jaycoxs offer 3D printing classes and services for anyone who is interested.
“I think 3D printing is goin g to be huge.It's going to have a huge effect 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.
3D printing services are becoming available for American consumers.The UPS Store is a nationwide retailer (零售商) that provides shipping,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.It's been much more than I would have imagined.”
The UPS Store plans to add 3D printers in three more stores.
At The UPS Store,the cost of the object depends on the amount of materials used.The store charges up to $ 95 an hour to design the object with computer software that creates a digital file to guide the printer.
Mr.Jaycox predicts that within five years,3D printing technology could become more popular.But KiChong Tran says even current technology can make a difference in a developing country like Cambodia.
“With 3D printing,you can give them tools;you put it in their hands so they are responsible more for their own development and they learn skills beyond just learning English and becoming a tour guide or something like that or working at a bank;you can actually create things that give value to the world.”
He says it's not just in Cambodia but anywhere where there is a 3D printer,it can turn a good idea into reality.
[语篇解读]这篇短文主要介绍了什么是3D打印技术,以及3D打印业务的发展情况。
16.The purpose of the passage is to ________.

Social Networking and Its Effects
Social networking has become an unquestionable part of our everyday lives.Those who have a life on the Internet do not always realize that they are losing their connections with the real world.Nowadays,a reputation online is more important.Some are even finding a way to make a living online.Social media seems to have quite the impact,especially on teenagers.
Years ago,before social networking existed,friends would go out and have a good time,and popularity in high school would be something of importance to a lot of people.Today,popularity means having a lot of followers on Twitter or Tumblr.Tumblr has its own way of creating “celebrities”.Users are considered “Tumblr famous”if they have a high number of followers.Websites make us think that greatness is achieved just because thousands of strangers are familiar with our face.Popularity is not about having a lot of friends any more;it is just about being known for absolutely nothing.
Social networking has its positives,considering it allows us to connect with friends and family in a matter of seconds.Although this is extremely useful,it is also destroying our ability to make real life conversations.People are attacked over the Internet,but do not say a word to each other in person.Social media is preventing us from standing up for ourselves the way we should be.Facebook limits our conversations that we have with people,which is why it is always better to strike up a conversation in person instead of through a computer screen.Social networking destroys the true meaning of human interaction.
Teens have found new ways to make a living out of advertisements that they post on their social networking pages.Social networks allow them to make money without even getting up off the couch.Being out in the real world and working creates ways to communicate and is a crucial part of life,but that will be destroyed if young teens think it is okay to just make money through social media.Social networking makes things easier,but that does not always mean that it makes things better.
Social networking affects young lives and causes teens to grow up differently from how their older relatives have.They rely on their blogs and pages to communicate with people,keep up with the latest trends and enjoy their separate little world.Social media has ruined how life should be: fun,adventurous and exciting.Instead,it has turned most teenagers into anti-social couch potatoes.There needs to be a break from social networking so young people can once again live a real life in the real world.。
