A company says it has completed the first 3D-printed home recently. The home was shown to reporters and visitors at a music festival.
The building company has developed large 3D- printers that build homes with mortar, a hard and strong
material. It uses robotics, computer programs and advanced materials to make houses.
Jason Ballard is the company's chief engineer. "So I'm standing in front of the first 3D-printed home in America. This house was actually printed in high winds, blowing dust and rain." It is important for the printing programmes to operate in bad weather conditions, such as weather disasters. The goal is to print homes in developing countries. So the printer has to be light enough to move from one property to the next.
Ballard imagines that someday, many 3D-printers will operate around the world to make homes. "It's actually a lot more simple to build a printer than it is to build a house," he said. "We ran this printer at about a quarter speed to print this house, and completed it in about 48 hours of print time."
The company developed this technology not to make money but to help provide a quick, cheap housing solution for the millions of people who need it most. There are about a billion people that don't have one of life's most basic human needs, and that's safe shelter.
Ballard says his company already works on housing needs with poor families in different areas. But he says that to really make a difference, the program will need to be greatly improved. He added that since the 3D-printing process is so much faster than traditional homebuilding, a whole community could be built in just a few months. He believes over time, people can get the new home below $4,000 with the help of 3D-printers.

A new robot, Pepper, has been designed. It is considered as the world's first with the ability to read human emotions. Pepper looks slightly like Michelin Man. It is four-feet tall with a computer in its chest and human-like hands. Although it is not tall, Pepper is able to talk about everything from the weather to the latest events about the country.
Using its functions, Pepper can react(反应) to people nearby -- making jokes, dancing and even singing in different languages. Pepper can understand expressions, human voice and actions, then react through computer programmes. The designer hopes to create a robot that can understand people well, then it can take action. He also hopes robots can play roles in many ways, not just work in the industry. They provide fun at the home or store. Pepper is designed to be a family robot. It is powered by love inside a family. He not only makes people laugh, but also comforts those people who are sad or lonely and encourage them when natural disasters come.
Pepper will be on sale in Japan for around US$2,000 in February 2015. For now, several Peppers are shown at some stores in Tokyo for visitors. The designers want the robots to get so much knowledge that they can succeed in communicating with humans better before sale.
Several thousand Peppers are going to learn at some stores. Everything they learned and got is going to be stored into the i-cloud service. So that they can share wisdom with each other
We are sure Pepper can bring amazing changes into our lives.

Choose the right sentences to complete the article.
Say you're sitting around with some friends playing video games and someone mentions a game that happens to be one of your favorites. “Oh, that game's easy. So don’t spend the time on it,” one of your friends says. The others agree. 1.
You have just experienced what is commonly referred to as peer (同伴)pressure, also called peer influence（影响）. You will take on a certain kind of behavior, dress, or attitude(态度) in order to be accepted as part of a group of your “peers “. As a teenager, it is possible for you to have experienced the influence of peer pressure in a number of different areas.
2. For teenagers, as school and other activities take you away from home, you may spend more time with your friends than with your family. As you become more independent, your peers naturally play a greater role in your life.
According to Dr. Casey from Cornell University, teenagers are very quick and correct in making decisions on their own and in situations where they have time to think .3. In a recent study, teenage volunteers played a video driving game, either alone or with friends watching. The researchers discovered that the number of risks（冒险） teenagers took more than doubled when their friends were watching, compared with when they played alone. This shows that teenagers may find it more difficult to control risky behavior when their friends are around, or in situations where they are very angry.
4. A teenager might join in a volunteer project because his or her friends are doing it, or get good grades because his or her friends think getting good grades is important. In fact, friends often encourage each other to study or try out for sports.
5. So when it comes to decision making, the choice is up to you.
A. We are all influenced by our peers at any age somehow.
B. Though you are always influenced by those around us, it is you that are always the final decision-maker.
C. Although you enjoy the game very much, not wanting to agree with them, you go along with them in the end.
D. Just as people can influence us to make foolish choices, they can also influence us to make good ones.
E. However, when they make decisions in the heat of the moment or in social situations, their decisions are often influenced by factors like peers.
