Question: Read the article and select the best answer. Article: I don't often lose things and I'm always careful with money, so I was quite surprised when I reached for my wallet and it wasn't there. At first, I thought it was possible that I could have left it at home. Then I remembered taking it out to pay the taxi, so I knew I had it with me just before I walked into the restaurant. I wondered if it was possible that it could have dropped out of my pocket while I was eating dinner. I turned and walked back to the table where I had been sitting. Unluckily, there were several people sitting at the table at that time, so I had the waiter go over to the table to see if my wallet was on the floor. While the waiter was looking for it, the head of the restaurant came up to me and asked me if anything was wrong. I told him what had happened. He asked me to report the missing wallet to the police. I told him I didn't want to do so; I was in a hurry because I had to reach my waiting room before two o'clock, where some people were waiting to see me. I also told him that my biggest worry at the moment was how I was going to pay for the meal. He told me not to worry about that. He asked me to write down my name and address, and he said he would send me a bill . Question: When the writer couldn't find his wallet, his first thought was that _ Options: A: it had been given to the taxi-driver B: he had dropped it in the taxi C: he had lost his wallet again D: it might be left at home

Question: Read the article and select the best answer. 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, what can't Valerie do now? Options: A: She gives directions around the Pittsburgh campus. B: She provides visitors information about the weather. C: She answers the telephone. D: She tells a story of a robot living in a human world.

Question: Read the article and select the best answer. Article: People with less education suffer fewer stressful days,according to a report in the current issue of the Journal of Health and Social Behavior. However,the study also found that when lesseducated people did suffer stress it was more severe and had a larger impact on their health. From this researchers have concluded that the daytoday factors that cause stress are not random .Where you are in society determines the kinds of problems that you have each day,and how well you will deal with them. The research team interviewed a national sample of 1,031 adults daily for eight days about their stress level and health.People without a high school diploma reported stress on 30 percent of the study days,people with a high school degree reported stress 38 percent of the time,and people with college degrees reported stress 44 percent of the time. "Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health."lead researcher Dr.Joseph Grzywacz,of Wake Forest University Medical Center,said in a prepared statement."The downward turns in heBaptistalth were connected with daily stressors and the effect of daily stressors on their health is much more devastating for the less advantaged." Grzywacz suggested followup research to determine why lesseducated people report fewer days of stress when it is known that their stress is more acute(severe)and chronic (lasting). "If something happens every day,maybe it's not seen as a stressor"Grzywacz says."Maybe it is just life." Question: Stress level is closely related to . Options: A: family size B: social status C: body weight D: work experience
