Article: Car companies are developing vehicles that will plug into electric sockets,just like many laptops,digital cameras,cell phones and Mp4 do.Called"plug-in vehicles",these cars will get most of their power from electricity. Their drivers won't have to stop at gas stations as often as usual. The technology is more than just cool. In our car-filled world,plug-in vehicles could reduce the amount of gas we use,which keeps rising in cost now and then. Besides,driving around in these vehicles may even help the environment.Gas-burning cars produce a lot of greenhouse gas,which causes globe warming. The first company-produced plug-in vehicles could hit the roads by 2010. But engineers still have a lot of work to do to make the technology practical and inexpensive. Batteries are the biggest challenge. In the plug-in-vehicle world,Li-ion batteries are getting the most attention.These batteries can store a large amount of energy in a small package,and they last a longer time between charges.Li-ion batteries can fit laptops,cell phones,heart instruments and other similar pocket ones. But because cars are so big and heavy, it would still require a suitcase-sized Li-ion batteries to power about 12km of driving.What's more,the batteries are much expensive. "A car filled with batteries could go a long distance,"says Ted Bohn, an electrical engineer in Chicago."But it couldn't pull any people.and it would cost $100,000." So researchers need to work out how to make batteries smaller and cheaper,among other questions. "The answers don't exist yet,"Bohn says,"As a kid,I thought someone someplace knows the answer to everything.All of these questions haven't been decided.That's what engineering is about-making a guess,running tests and getting fine results." Question: Which is true according to the passage? Options: A: The"plug-in vehicles"will use electricity completely as driving power. B: The new technology will help protect our environment. C: The technology of using electricity as driving is quite practical now. D: The biggest challenge of the new technology is that it will cost us more energy.

Now, US scientists have discovered not only does retail therapy exist,but that it could be caused by an individual's fear of sudden death. Researchers found materialistic people thought terrorism and war more stressful than others. Psychologists believe the rise of materialism around the world and its treatment effect on extreme stress might be a response to fear of death caused by acts of terrorism, disease and natural disasters. The scientists from Michigan State University said people with possession obsessions often have lower self-esteem than others so are more likely to shop as the result of severe psychological suffering. Ayalla Ruvio,a business professor studying people's shopping habits while rockets fell in Israel, said, "When the going gets tough, the materialistic people go shopping. This stress spending is likely to produce even greater stress and lower well-being. Essentially, materialism appears to make bad events even worse. Dr Ruvio led a two-part study of Israeli citizens living in a town that came under extreme rocket attacks for about six months in 2007. She compared 139 residents of the southern town with 170 from another town that was not under attack to see how their symptoms of post-traumatic stress and shopping habits varied. Dr Ruvio found that, when faced with a deadly threat, those who are highly materialistic suffered much higher levels of stress,while their tendency to shop was increased. Dr Ruvio said, "The relationship between materialism and stress may be more harmful than commonly thought." The second stage of their research surveyed 855 Americans about their materialistic nature and fear of death. They found shopping was used to relieve feelings of stress and anxiety about death but this was in response to fear of a variety of life-threatening events like car accidents, criminal attacks and natural disasters. Question: Which of the following opinion is NOT right according to the text? Options: A: Terrorism is believed to easily cause the rise of materialism. B: The materialistic find terrorism and war more stressful than others. C: The scientists think possession obsessions help people get self-respect. D: The scientists think people with possession obsessions suffer a lot mentally.

Read the article and select the best answer. Article: My House My mother moved a lot when she was growing up on account of Grandpa being in the army. She hated having to adjust to new schools and make new friends. That's why I thought she was joking when she put forward the idea of moving. But she was completely serious. "For just the two of us," my mother said, "an apartment in the city will suit our needs much better." Personally, I think she's lost her mind. I guess I can understand why she would want to move, but what about me and what this house means to me? I suppose if you looked at my house, you might think it was just another country house. But to me it is anything but standard. I moved into this house with my parents ten years ago. I can still remember that first day like it was yesterday. The first thing I noticed was the big front yard. To me it seemed like an ocean of grass--I couldn't wait to dive in. The backyard was full of gnarled (, ) and scary trees that talk on windy nights. But I grew to like them and the shadows they cast in my room. My father and I even built a small tree house, where I often go to remember all the wonderful times we had before Father's death. This house is special--maybe only to me--but special nevertheless. It's the little seemingly insignificant things that make this house so special to me: the ice-cold tile floors that make me tremble on midnight snack runs; the smell of my father's pipe that still exists; the towering bookcases of my mother; the view outside my bedroom window. This house holds too many memories, memories which would be lost if we gave it up. Question: How did the author let us feel that the house was special to her? Options: A: By arguing whether the house was standard. B: By explaining why the house suited their needs. C: By describing the s D: By comparing the differences between country and city life.
