[Q]: Article: She might not be paid, but Carnegie Mellon University's newest staff member does all that a typical receptionist can do: give directions, answer the phone -- and even gossip about her life. University officials revealed what it considers to be the world's first robot receptionist with a personality of her own. The blond  receptionist, named "Valerie," puts on a headset and interacts with people by talking about her boss, her psychiatrist  and her dream. Valerie, the roboceptionist, sits in a custom-made booth at the entrance of a computer science hall. With her ability to distinguish motion, she greets visitors as they come near. Type in a question on a keyboard and she gives directions around the Pittsburgh campus and provides visitors information about the weather. More than that, she tells stories about her life. From her              booth, passers-by often can hear her talking              on the phone. She recognizes when someone is in front of her and remembers their characteristics. She can change between tasks from talking on the phone to answering a question. Valerie, however, does have her limit. She is a drum-shaped mechanical device with a digitally lively face that appears on a computer display. Visitors have to type on a keyboard to communicate with her. And she understands only simple questions. Eventually her creators would like to install face recognition so people don't have to insert an identity card for her to remember them. And people won't have to type their questions on a keyboard if they can solve the problem of voice recognition in a crowded hall. Valerie will tell the story of a robot living in a human world. 
 Question: According to the passage we know that  _  . 
 Options: (A) Valerie looks like a real beautiful woman (B) Valerie can do whatever a human receptionist can't (C) Visitors can have a conversation with Valerie (D) Valerie doesn't understand of the visitors' questions sometimes
[A]: D


[Q]: Article: In the market of luxury   brands, Chinese consumers are only second to the Japanese in the world. Across the globe it's clear that the young generation are increasingly relying on expensive brands for their self-image. Personally I am a fashion-lover, at least in spirit. I love to look at clothes and shoes. But I don't understand why people spend large amounts of money on designer labels. Certainly, young people, whether in China or elsewhere, should be building their self-confidence in other ways. When a young woman shows off a handbag worth two months' salary, that's a scary thing. What are the psychological factors forcing young people to take on debt for designer items? The desire to say, "Hey, look at me. I'm wealthy. I have social status." Scientists have found the acquisition of luxury brands doesn't lead to happiness. Study after study has shown that, although we are born to desire material possessions, when we get them, we don't suddenly become "happy people". In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, have shown that individuals who invest   in travel and other experiences get more pleasure than those who invest in material things. That's because experiences are more easily combined into a person's identity. If I travel to Yunnan, that adventure affects how I think. My memories entertain my friends and colleagues. It follows, then, that investing in experiences improves my chances for successful social relationships. Moreover, as Van Boven has observed, young people who pursue happiness through "things" are liked less by others than young people who seek happiness through experiences.  This research is pretty solid, but I suspect it won't persuade young people not to desire a style. It's natural to want to express yourself through your appearance. So my advice is, create a look that isn't tied to a designer label.  You don't have to  _ to send a message about who you are. Take a trip. Go out into the world. Then come back and confidently create your own signature look. 
 Question: This passage is written here in order to   _  . 
 Options: (A) encourage young people to travel (B) persuade young people to seek experience happiness (C) report the result of a series of researches (D) advise young people to save money
[A]: B


[Q]: Article: I went through a training program and became a literacy volunteer last surnmen The training I received, though excellent, did not tell me how it was to work with a real student, however. When I began to discover what other people's lives were like because they could not read, I realized the true importance of reading. My first student Marie was a 44-year-old single mother of three. In the first lesson, I found out she walked two miles to the nearest supermarket twice a week because she didn't know which bus to take. When I told her I would get her a bus schedule, she told me it would not help because she could not  read it. She said she also had difficulty once she got to the supermarket,because she couldn't always remember what she needed. Since she did not know words, she could not write out a shopping list. Also, she could only recognize items by sight, so if the product had a different label, she would not recognize it as the product she wanted. As we worked together, learning how to read built Marie's self-confidence,which encouraged her to continue her studies. She began to make rapid progress and was even able to take the bus to the supermarketelt. After this successful trip, she reported how self-confident she felt. At the end of the program, she began helping her youngest son,Tony, a shy first grader with his reading. She sat with him before he went to sleep and together they would read bedtime stories. When his eyes became wide with excitement as she read, pride was written all over her face. As she described this experience, I was proud of myself as well. I found that helping Marie to build her self-confidence was more rewarding than anything I had ever done before. As a literacy volunteer, I learned a great deal about teaching and helping others. In fact, I may have learned more from the experience than Marie did.
