Read the following article and answer the question. Article: Architects say they will soon be able to print a whole house by simply using a 3D printer. The technology is still ly new, but it's already being used in the medical world and in industry to bring down the cost of precision parts. Now designers in the Netherlands are planning to create a complete building. If it all goes to plan, you will see the first house to be made from 3D printing before long. It's been named the Landscape House. Following its success across different industries, Dutch architect Ruijssenaars believes printing technology has come far enough to create the first full size building. He said, "With 3D printing, you can actually directly print the shape that you want without first having to make the mould. It is not only an interesting technique, because you have actually density of printing that you can later see in the product, but it's also economically (better) because you save time and energy." To create his design with traditional construction methods, builders would have to pour concrete into specially constructed moulds and these would have to be removed once the concrete had set. The house will occupy about 1.115 square meters and if it stays within the projected budget, it is predicted to cost between 5 and 6 million US dollars. The house will occupy about will employ is the creation of Enrico Dini. He said, "My personal approach in 3D printing of building construction is: using 3D printing as our start basis of making free form cages and from then move on with the traditional construction technique." This is Dini's printer. It's big, measuring 5 meters by 3 meters. But his company D-Shape is planning to produce a new giant 3D printer, which can construct the Landscape House. Ground rock, or sand is put into the printer and then hardened by a binding agent .The 3D printer will print pillars that would go up straight. The project is expected to be completed sometime in 2014. Question: Compared with traditional printing method, 3D printing _ . Answer:
OPTIONS:
- does not need concrete and sand
- ly saves time and energy
- has been used in the fields of arts
- needs specially constructed moulds

Answer: ly saves time and energy

Read the following article and answer the question. Article: Students and Technology in the Classroom I love my blackberry -- it's my little connection to the larger world that can go anywhere with me. I also love my laptop computer,as it holds all of my writing and thoughts. Despite this love of technology, I know that there are times when I need to move away from these devices and truly communicate with others. On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom, I have a rule -- no laptop, iPads, phones ,etc .When students were told my rule in advance of the class, some of them were not happy. Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There's a bit of truth to that. Some students assume that I am anti-technology. There's no truth in that at all. I love technology and try to keep up with it so I can relate to my students. The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly _ complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course the material and the class discussion. I've been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course material beyond the classroom. I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I'm... Question: According to the author, the use of technology in the classroom may _ . Answer:
OPTIONS:
- keep students from doing independent thinking
- encourage students to have in-depth conversations
- help students to better understand complex themes
- affect students' concentration on course evaluation

Answer: keep students from doing independent thinking

Read the following article and answer the question. Article: Most people follow others blindly just under the effect of peer pressure or because they feel it safe to follow a large number of people. In some rare cases it might be right to follow the crowd, but in most cases this' can be a big mistake. Actually there are reasons why we shouldn't follow the crowd blindly. According to a study, people often follow the crowd when they aren't sure about the direction they should take. This means a large number of people could be following others without understanding what's right and what's wrong! This makes more people follow and as a result most people move in a certain direction even if it isn't right. A man who wants to be successful always hopes for others' guidance and he usually follows the same path of most people, but the question this man never asks himself is: are all of those people successful ?Of course not! If you want to follow a crowd, then follow a successful one. However, in real life you'll only find one successful person among hundreds of people , and that's why following the crowd makes no sense at all Most people act emotionally without thinking wisely. If you always follow others because they're greater than you in number, then sooner or later you'll discover that you're taking emo- tional decisions you might regret later. However. should we never follow the crowd? No. I'm not trying to say you should never follow the crowd, but instead I'm just asking you to think wisely before you take a decision. lf you find others are right, there is no problem in following them, but if you have doubts about the direction they're moving in, don't follow them blindly. Question: What opinion does the author hold? Answer:
OPTIONS:
- It is wrong to follow other people.
- It takes time to think wisely.
- You should use your brain before following others.
- You shouldn't be sorry for what you have done.
