[EX Q]: Article: How do people traditionally manufacture things? They usually start with a sheet of metal, wood or other material and cut, drill and shave it to create a desired shape. Sometimes, they use a mold made of metal or sand, pour liquid plastic or metal into it and let it cool to create a solid part. Now, a completely different method is gaining popularity. On Oct. 9, 2013, London Science Museum kicked off its new exhibition, 3-D: Printing the Future, with over 600 3-D printed objects on display, including space probes , toy dolls and even human organs - basically any product you can think of, reported Live Science. You might find it hard to believe that an object can actually be "printed out" like a picture. But it is not that hard to understand how it works. Just as a traditional printer sprays ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape. Instead of ink, the materials the 3-D printer uses are mainly plastic, resin and certain metals. The thinner each layer is - from a millimeter to less than the width of a hair - the smoother and finer the object will be. And objects always come out in one piece, sparing you the trouble of putting different parts together afterward. For example, 10 years ago a desktop 3-D printer might have cost PS20,000 (200,000 yuan), while now it costs only about PS1,000, according to the BBC. In fact, 3-D printers have been around for some time, but until recently they hadn't been very popular since few people could afford them. Last year, though, saw a big decrease in the price of 3-D printers. However, as 3-D printing technology becomes more commonplace, it may trigger certain problems. One of them is piracy . "Once you can download a coffee maker, or print out a new set of kitchen utensils on your personal 3-D printer, who will visit a retail store again?" an expert on 3-D printing told Forbes News. Even more frightening, the world's first 3-D printed gun was successfully fired in the US in May of this year, which means that 3-D printing could potentially give more people access to weapons.
Question: According to the article, in the future, 3-D printing technology will probably _ .
Options: (A) change the way people make products (B) be applied as widely in our daily lives as computers (C) forbid many countries to make purchases of weapons (D) take the place of normal printers and save lots of energy
Asnwer: A
[EX A]: Yes

[EX Q]: Article: When Danny Wallace, 26, got bored, he put an ad on the worldwide web reading simply: "Join Me. Send a passport photo." A year and a half later his east London flat is the headquarters for a global internet-based "club" whose members carry out good deeds for strangers every Friday. It's not common for people in London to talk to strangers. If you see someone struggling with something, part of the brain goes "I want to help". But the trained part of the brain says: "They will think you are mad or going to mug them", so you walk away. Join Me now has about 3,000 members around the world who do an act of kindness every Friday. For example, I'm usually out on a Friday so I go for one of the standard acts -- the unexpected cup of coffee. You might be sitting in a cafe and see an old man in the corner drinking coffee or tea, and you walk up with another cup of whatever they are drinking , and say: " I've bought you a coffee" and walk away. It's a pleasure to see the look of surprise on their faces. There can be some suspicion, but I think that was mostly in the early days when I didn't know how to do it properly. I would walk up quite nervously like I was doing something wrong and I didn't know when to leave. In the end, I learned through _ . Sometimes it worked, other times it didn't. I discovered that you have to walk up with confidence and humour and not "get in their faces". You say: "This is for you", then you go. It's hit-and-run kindness. And there is no point in doing it half-heartedly. You've got to do it because you really mean it. Join Me is without geographical boundaries, but there are quite a few members in London, and such stories about things happen on the underground or on the buses. One lady got on the bus and put a PS10 note down and said: "That's for me and the next nine people". So at every stop, anyone who got on was told it was paid for. A lot of people were doing this sort of thing anyway. For them it's an excuse or reason to do something nice for a complete stranger, and it gives them the confidence to walk up and start chatting.
Question: When Londoners see someone in trouble, they _ .
Options: (A) often give a hand (B) pretend not to have seen it (C) stop and ask questions (D) telephone the police
Asnwer: A
[EX A]:
No
