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

Article: Coral reefs are not just beautiful to look at,but also very useful.They shelter nearly 25% of ocean life and provide food for billions of people.However, like many other species,this amazing ecosystem is in danger of dying out! There are two main reasons for the destruction--the rising carbon dioxide levels caused by global warming as well as human influences like bottom operation.While not much can be done about the former,the loss caused by the latter can be reduced. Bottom operation involves dropping nets to the ocean bed and then dragging them up when filled with fish.This action damaged the ocean floor,causing the coral branches to separate from the reefs.While that is very discouraging,the good news is that if these branches are found quickly,they can be saved.At present,that work is being performed by volunteer divers. But the method has only limited success because they cannot stay long underwater, nor reach depths of over 200 meters where some of the deep-sea coral grows. However,this is not the case for Coralbots--the robots that can constantly seek out broken branches.A team of 'coral bots',each individually working to simple rules will piece together damaged bits of coral, allowing them to regrow. They are programmed to be able to distinguish between other things and the coral.The robots work together in groups,similar to bees.If one coralbot is damaged, then the others will still be able to complete the task. Dr Lea-Anne Henry said:"The project of using coralbots offers us the possibility to restore the function of reefs.It is in the final stage of testing.Once ready, the researchers hope to build hundreds of _ and use them effectively in the waters off Scotland and then hopefully in the oceans across the world."
Question: Which of the following is a cause of the danger that coral reefs are facing?
Options: (A) The appearance of new creatures. (B) The seriously polluted sea water. (C) The activities of volunteer divers. (D) Human activities like bottom operation.
Asnwer: D

Article: I was in my third year of teaching writing at Ralph High School in New York, when one of my students,15-year-old Mikey,gave me a note from his mother.It explained his absence from class the day before: "Dear Mr. McCort,Mikey's grandmother,who is eighty years of age,fell down the stairs from too much coffee and I kept Mikey at home to take care of her and his baby sister so I couldn't go to my job. Please excuse Mikey and he'll do his best in the future.P.S.His grandmother is OK." I had seen Mikey writing the note at his desk.I said nothing.Most parental-excuse note, I received were penned by my students.The writers of those notes didn't realize that honest excuse notes were usually dull: "Peter was late because the alarm clock didn't go off." The students always said it was hard putting 200 words together on any subject, but when they produced excuse notes, they were excellent.So I decided to give the first class to study the art of the excuse note. "Today I'd like you to write 'An Excuse Note from Adam to God' or 'An Excuse Note from Eve to God'."Heads went down.Pens raced across paper.They had to be asked to go to lunch by their friends. The next day everyone had excuse notes.Heated discussions followed.But suddenly I saw the headmaster at the door.He entered the classroom and walked up and down,looking at papers,and then said."I'd like you to see me in my office."My heart sank. When I stepped into his office,he came to shake my hand and said,"I just want to tell you that lesson, that ask, was great.Those kids were writing on the college level.Thank you."

Options: (A) somewhere enjoying himself (B) taking care of his baby sister (C) looking after his grandmother (D) studying the art of the excuse note
