Article: Faces that activate the same regions of the brain again and again are more likely to be remtembered. Practice makes perfect when it comes to remembering things, but exactly how that works has long been a mystery. A study published in Science recently indicates that reactivating neural patterns over and over again my store items into the memory. People find it easier to recall things if material is presented repeatedly at well-spaced intervals rather than all at once. For example, you're more likely to remember a face that your've seen on some occasions over a few days than one that you've seen once in one long period. One reason that a face linked to many different contexts -such as school, work and home- is easier to recognize than one that is associated with just one setting, such as a party, could be that there are some ways to access the memory. This idea, called the encoding variability hypothesis ,was proposed by psychologists about 40 years ago. Each different context or setting activates a clear set of brain regions; the hypothesis suggests that it is these differing neural responses that improve the memory. But neuroimaging research led by Russell Poldrack, a scientist at the University of Texas. Austin, now suggests that the opposite is true--items are better remembered when they activate the same neural patterns with each exposure. Poldrack's team measured brain activity in 24 people using functional magnetic resonance imaging. The subjects saw 120 unfamiliar faces, and each one repeated four times at varying intervals during the scan. One hour later, they were shown the faces again, mixed with 120 new ones, and asked to rate the familiarity of each. The researchers then looked at the brain responses that had been recorded when the subjects wee first shown the faces, focusing on 20 brain regions associated with visual perception and memory. Face that were later recognized evoked similar activation patterns at each repetition in nine of the regions, particularly those associated with object and face perception; faces that were later forgotten did not produce such pattern to the same extent in people's mind

Article: Miami Beach is a top destination for vacationers from around the world --not to mention a location for sea turtles laying eggs. For years, female sea turtles have returned to the beaches where they were born to build nests for their next generation. As Miami Beach continues to develop; wildlife officials and volunteers are making sure the beach remains a welcoming place for these endangered animals. The sea turtle patrol starts his day at sunrise. "The reason we need to get out at first light is to make sure we see the tracks before anybody else gets out here, Bill Ahern says, "Something that weighs 350 pounds is going to leave evidence." Bill Ahern directs the sea turtle program in Miami-Dade county. His team monitors and marks nests left by sea turtles who lay eggs in the sand and then return to the sea. The patrols also work with beach residents to keep track of new nests and possible threats to existing ones. Nearly 65,000 turtles nested on Florida's Atlantic coast last year. A tiny part comes to Miami Beach where they face many risks. Tough laws have been passed to punishpoachers . And bright lights from nearby buildings can confuse newly born turtles, attracting them onto roads instead of into the ocean. "I recall in the mid-1960s, me and my beach buddies(policemen) would pick up hatchlings from the road and put them back in the water," he recalls .To avoid that problem, city officials have imposed limits on coastal lighting. Although most sea turtles hatch on their own, coming out at night, some have a harder time. In the future, the Sea Turtles Program hopes to do away with the hatchery. Educating beach-goers is a step in that direction. Each week, people are invited to see a release of newly born turtles recovered from nests. The experience helps sunbathers understand the role of the beach in the turtle's life cycle. "Only a part of the newly hatched turtles will escape predators and man-made dangers in their first year." Their instincts are so sharp ," Ahern says, "I'll face a turtle to the west, and then watch him, he turns right around ,facing the ocean. "
Question: What do Ahern and his sea turtle patrol do in the early morning?
Options: (A) find tracks left by sea turtles (B) pick up the trash on the beach (C) collect eggs laid by sea turtles (D) exercise to lose weight
Asnwer: A
answer:
Yes

question:
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: C
answer:
No
