Have you ever tried 3-D printing? A team of seven students from No. 34 Middle School in Zhengzhou, Henan, have won awards for their creative 3-D printing works.
Two of the team's works took home the top prize at the International Youth Innovation Design Competition. It was held in France this summer. One of their works had the theme "China's New Era (时代) ". The other work was an ancient Chinese palace. They sent the work as a gift to local officials in Lille, France.
The team members learned how to print in their school's 3-D printing club. They took classes twice a week to learn 3-D printing. To make 3-D printed items, they first draw a blueprint (蓝图) . Then, they use a computer to design models of the pieces they need. After that, they use a 3-D printer to print the pieces and assemble (组装) them, as Liu Songyuan, 14, said.
But knowing how to use the tools is just one part of mastering 3-D printing. One also has to have imagination. To show the theme "China's New Era", they printed out items standing for high-speed trains, bike sharing, cashless payment and online shopping. They placed these items around a dragon, which represented China. They made this work within just three hours, winning a national 3-D printing competition in China and later the international competition.
When they got to the international competition, they wanted to present something that stood for traditional Chinese culture. They were inspired (启迪) by a trip to the palace Museum. "When we saw the buildings there, we thought 'That's it!" said Zhang Jiuxing, 14. They took photos of the buildings and did a lot of research to make their 3-D-printed works more realistic (逼真的) . "We will continue to learn about this technology and make more creative things, "Zhang added.
1.How many students are there in the team?
A.8. B.2. C.6. D.7.
2.Which country held the International Youth Innovation Design Competition?
A.Russia. B.The UK. C.China. D.France
3.How often did the team members take classes to learn 3-D printing?
A.Twice a week B.Once a week. C.Once a month. D.Three times a week.
4.According to Liu Songyuan, what's the right order to make 3-D-printed items?
① They use a computer to design models of the pieces they need.
② They use a 3-D printer to print the pieces and assemble them.
③ They draw a blueprint.
A.①②③ B.②③① C.③①② D.③②①
5.From the passage we can learn that____________________.
A.if you know how to use the tools, you can master 3-D printing
B.it's still a long way for the students to make creative and realistic 3-D works
C.it's easy for the students to make a 3-D-printed work

Have you ever wanted to try on clothes without going to the trouble of getting undressed? If you have, here’s the device for you: the virtual(虚拟的) fitting room.
The technology, designed by Russian company AR Door, was first tried out in May. When a customer walks into a “fitting” room, they’ll stand in front of a big screen that looks like a mirror. A camera in the mirror, using Microsoft Kinect, monitors a customer’s movement and projects a 3-D image of the clothes onto you while you stand before a screen.
The room also uses augmented reality technology. “Augmented reality allows the customers to select an item of clothing without having to try it on physically,” the company told the Daily Mail. A customer can spin around to see all angles(角度) of the clothes, and can control the program by pushing virtual buttons.
AR Door is not the only company to be developing technology to help people with the way they look. Japanese company Shiseido recently presented its Magic Mirror, a virtual make-up mirror that allows people to get a full makeover in seconds.
However, the technology is not perfect. The clothes still seem to hang on the surface of the body, rather than look like the customer is actually wearing them. And people shopping for clothes are probably still better off actually trying them on.
In the end, you won’t know how something really looks and feels.
1.The virtual fitting room is technology that_____________.
A. allows people to watch a movie while trying on clothes
B. can help people buy clothes on the Internet
C. allows people to walk freely in the fitting room
D. can help people select clothes without having to try them on
2.Which of the following is NOT true?
A. The virtual fitting room was invented in Russia.
B. The virtual fitting room and the virtual make-up mirror both use the augmented reality technology to help people with the way they look.
C. The customer can control the program by pushing virtual buttons.
D. The customer looks like he/she is actually wearing the clothes while using this technology.
3.In the virtual fitting room, what is on the screen?
A. A computer B. A camera
C. A fitting room D. A shop assistant
4.From the last paragraph, we can learn that____________.
A. few people shop for clothes in clothing stores
B. the magic mirror is now widely used
C. people still need to try on clothes before buying them
D. the virtual fitting room is perfect

Creator of e-mail makes use of ‘@’ sign
Does your class use e-mail? Have you ever tried to write a story for our newspaper and send it in by e-mail? E-mail is used for everything, and it makes life easier． But do you know where e-mail came from?
The man who invented it was Ray Tomlinson, a US engineer． He died early last month at the age of 74．
Back in 1971, Tomlinson was working on something that could send messages from one computer to another． Tomlinson tried to find a way to separate users’ name from the names of their computers． He needed some kind of symbol (符号)． However, it couldn’t be a popular one, and it couldn’t be one that computers might know in a different context (语境)． It also needed to be on keyboard at the same time． The “@” sign was there, and pretty much no one used it． It was perfect．
“The ‘@’ sign made the most sense,” he told Wired in 2012． “It said where the user was…at．” For example, by writing “Alex at 21st Century Teens” you can send a message to somebody named Alex who works at 21st Century Teens． This was the early form of email．
The interesting thing is that Tomlinson didn’t remember what the very first test message he sent was． “Probably the first message was QWERTYUIOP or something like that,” Yahoo reported, guessing the first row of letters on the keyboard．
Tomlinson, the father of e-mail, changed the way the world communicates and more importantly saved the symbol “@”．
Today, the “@” symbol is finding new life outside of our inboxes (收件箱)． Most famously, social media like Weibo and Wechat use it at the beginning of user names． So even if we don’t use e-mail some day, Tomlinson’s contribution (贡献) will certainly live on．
1.Who invented the e-mail?
_____________________________________________________________________
2.When did he invent the e-mail?
_____________________________________________________________________
3.Why did he choose the symbol “@”?

4.What does “@” sign tell us?
