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.What can 3D printers do according to the passage?

Dear new moms,
You should teach your children manners (礼仪) as soon as your children can understand what you’re saying. When your children do something right, let them know. When your children do something wrong, tell them how they should do it and why.
Here are some basic manners for children:
1. Wait for their turn and don’t interrupt other people when they are speaking. Tell them to wait until someone finishes speaking, and then ask questions.
2. Always greet the people who come over to your house. You can teach your children to shake hands with grown-ups (成年人) who come over, but it’s not necessary to shake hands with other children. Your children should always say “hello” or “hi” when someone comes to your home so that the guest (客人) feels welcome.
3. Say “please” and “Thank you” often. And say “You’re welcome” to answer others’ “Thank you”.
4. After playing a game, no matter what the result is, be pleased. If your children win, tell them not to show off (炫耀), but to be kind. If they lose, tell them not to get mad and tell the other children that they did a good job or speak well of them.
Yours

Hi Lingling,
Thanks for your last message. It was great to hear from you, and I can’t wait to meet you.
I hope you will know me from my photo when I arrive at the airport. I am quite tall , with short fair hair, and I wear glasses. I’ll wear jeans and a T-shirt for the journey, but I’ll also carry my warm coat. I’ve got your photo--- you look very pretty. I’m sure we’ll find each other!
Thanks for telling me about your hobbies. You sound just like me! I spend a lot of time playing classical music with my friends at school, but I also like dance music---I love dancing! I enjoy sports as well, especially tennis. My brother is in the school tennis team--- I’m very proud of him! He is good at everything, but I’m not. Sometimes I get bad marks at school, and I feel sad. I should work harder.
You asked me, “How do you feel about coming to China” Well, I often feel a bit sad at first when I leave my mum and dad for a few days, and I’m quite shy when I am with strangers. I feel nervous when I speak Chinese, but I’ll be fine in a few days. I’m always sorry when I don’t know how to do things in the right way, so please help me when I am with you in China! Oh, I’m afraid of flying too. But I can’t tell you how excited I am about going to China!
See you next week!
