When Christopher Columbus landed on the then unnamed Costa Rica in 1502, he saw many Indians wearing gold earrings. So he thought the land must be rich in gold. He named the place Costa Rica, which means “rich coast” in Spanish.
Though little gold was found, Costa Rica today is indeed rich with coffee and bananas. Coffee is the most important product in Costa Rica and most of it is exported to other countries like America and West Germany. Bananas are the country’s second most important export. Costa Ricans also grow many other crops such as fruits, corn and beans for their own use. Costa Ricans love colors and their houses are painted in bright colors.
Education is very important to the Costa Ricans. Almost every village has a school and education is a must for children between seven and fourteen years of age. Boys and girls go to separate schools. Classes begin in March and end in November. The other three months of the year are harvest time and the children have to help their parents to pick coffee beans.What’s the main idea of the first paragraph?

Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into a physical object．This is now possible with the help of 3D printers．Such machines were once used just by universities and big companies．But now, stores with 3D printing services are appearing around the United States．
Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago．The store is filled with tools like a laser cutter, an industrial sewing machine and 3D printers．Bryan Jaycox requires $ 15 an hour to print an object．He also charges a fee depending on the size of the object and up to $ 50 an hour for design and labor services．
The Jaycoxs also offer 3D printing classes for anyone who is interested．One of the students in a recent class was Ki Chong Tran．He plans to open a 3D printing business in Cambodia．"The demand has been amazing．It's been much more than I would have imagined," said Ki Chong Tran．
"I think 3D printing is going to be huge． It's going to make a huge impact on society as a whole," he added．
Mr Jaycox predicts that within five years, 3D printing technology could become
more consumer friendly．
But Ki Chong Tran says even current technology can make a difference in a developing country like Cambodia．"With 3D printing you can give them tools, and you put it in their hands so they are responsible more for their own development．
They learn skills beyond just learning English and becoming a tour guide or something like that or working at a bank．You can actually create things that give value to the world," said Ki Chong Tran．
He says it's not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality．We learn from Paragraph l that 3D printing_________．
| A．is now available to ordinary people |

Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It’s awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.
It may sound risky, so many teens stay within their own social circles to find rides, and don’t branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.
“I think the digital connection of young people is really key, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they’ve been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.
The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn’t the car any more because there’s technology out there connecting you to a car.”
According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver’s license compared to six in ten today. So it’s not that surprising that on my 16th birthday I wasn’t rushing to get a license but an iPhone.
“Driving, for young people, does mean they have to disconnect from their technology, and that’s a negative. So if they could sit in the passage side and still be connected, that’s going to be a plus.” Schor continued. www..com
To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.The American teens like the author, prefer to possess an iPhone as a birthday gift because _______.
| A．it is most fashionable and cool |
| B．they are bored with driving cars |
| C．they are fond of being connected |
| D．it is much cheaper than a car |
We can learn from the text that _______.
| A．Twitter is a website for teens to make friends and achieve goals |
| B．ridesharing can be seen as a sign that people still count on each other |
| C．driving cars for teens means a plus and connecting with technology |
| D．having a car and cost-sharing symbolize more freedom for the author’s mother |
Professor Juliet would agree that _______.
| A．young people will sit waiting to be contacted by reading a passage |
| B．sharing economy is bound to be responsible for the recession |
| C．young people tend to share a car with strangers by means of Twitter |
| D．being connected via technology comes first for young people |
The best title for the passage is probably _______.
| A．Twitter, an Awesome Website |
| B．Cars or iPhone |
| C．Teens Use Twitter to Thumb Rides |
| D．Cool Teens on the Go |

While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful．Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence．
For their study, biologist Corson Miller and his team exposés eleven selected dogs to digital images of women that were either angry or happy．Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry．
Interestingly, the dogs were not provided with the entire face．Some dogs were show Ti only upper halves while the others observed lower halves．That's because the scientists believe humans show their eruptions on their equities face．
After some training ill．e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions．
They also found those being trained to read angry expressions took a longer time to learn．They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly．However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear．In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed．
The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly．Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner．How did the scientists conduct the experiment?
| A．By leaving dogs to women who are either happy or angry． |
| B．By mixing the selected dogs together． |
| C．By rewarding only half of the dogs touching the screen． |
| D．By showing digital pictures of women's happy or angry faces． |
Which of the following statements is TRUE?
| A．The dogs were not all provided with the entire face, |
| B．According to their size, the dogs were given either upper or lower halves． |
| C．The dogs could read even small changes that accountancy facial expressions after some training． |
| D．The dogs couldn't read strangers facial emotions． |
The underlined word "trepidation" in Paragraph 5 probably means .
| A．horror | B．curiosity |
| C．excitement | D．doubt |
How might the results change if the dogs with female owners are shown pictures of male faces?
| A．They could only tell commotions on partial faces rather than on entire face's． |
| B．They found it hard to tell the moods on the faces of a different gender． |
| C．They found it easy to tell the emotions on the entire -face． |
| D．They would be scared away at the sight of the pictures． |
Most artists have a favorite material they like to work with．For 28-year-old Kristen Alice, it happens to be garbage．The eco-friendly designer uses her incredible talent to transform garbage like empty drink bottles and candy wrappers into charming dresses that sell for thousands of dollars．
Kristen says the idea came to her after she saw how much vaster she and her three college roommates generated on a daily basis．The Fine Arts student began to dream about transforming the deserted bags and packages into beautiful garments．
Her first dress’ made from plastic bags and rolled magazines was strange, fun and even charming．However, she only made it to test her creativity．
The young designer did not consider starting a commercial venture（企业）until she spent a week working at Couture Fashion Week in New York City．There she observed the excitement generated by new and vintage（复古的）looks and decided to see if her unusual idea would result in as much enthusiasm．She began by creating a line of 12 garbage-inspired dresses．They were a huge success．
Today her company that has offices in Palm Beach, Florida and New York City, produces a wide variety of dresses ranging from cocktail dresses to ball gowns （礼服）．Kristen, of course, doesn't search garbage cans for her material anymore．Instead, she seeks it from companies that have produced more than they need and are planning to throw away the extras．
However, if you think the garbage-inspired dresses come cheap, think again．The price for ready-made creations retails（零售）from $500 to $1,500．Though that may appear expensive, the designer says she has no shortage of customers．In fact she now even has garbage-inspired clothing for men that includes jackets, ties, trousers and even board shorts! While most of the clothes are strong enough to resist multiple wears, whether they can be cleaned is a little unclear:What made Kristen think of using trash as her favorite material?
| A．Her poor living conditions at college． |
| B．The education from her parents not to waste anything useful． |
| C．Her roommates' advice of using garbage to replace ordinary material． |
| D．Her consciousness of environmental protection and trained eyes． |
