I'm taking a test and have to guess the right answer to the question after the article. 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: The passage mainly talks about_of a new car Options: A: the developing B: the speed C: the appearance D: the batteries

I'm taking a test and have to guess the right answer to the question after the article. Article: In the Netherlands,cycling isn't seen as eccrfriendly exercise; it's part of everyday life, as it's people's top choice to school and work. There are more bicycles than residents in the Netherlands. In cities like Amsterdam and The Hague, up to 70 percent of all journeys are made by bike. So how did cycling become such a popular means of transportation in the European country? In the 1970s, the Dutch government began to improve its cycling infrastructure due to both a social movement demanding safer cycling condition for children and the oil crisis in the Middle East, when oil producing countries stopped their exports to Western Europe. To make cycling safer and more appealing, the Dutch have built the widest cycling net- work in the world. The country has over 40,000 kilometers of bicycle lanes and paths,which are clearly marked. They have smooth surfaces,separate signs and lights for those on two wheels. The lanes are wide enough to allow side-by-side cycling and passing. In many cities the bike lanes are completely segregated from motorized traffic. And in many traffic situations cyclists are given priority over drivers. Sometimes, where space is limited and both must share, you can see signs showing an image of a cyclist with a car behind accompanied by the words "Bike Street:Cars are guests". As young people aren't allowed to drive alone until they are 18,cycling offers Dutch teen- agers an alternative form of freedom. The government also makes cycling training lessons a compulsory part of the Dutch school curriculum . Bike parking facilities are ubiquitous in the country. Cyclists are accommodated in the way motorists are elsewhere. Take Groningen, a city in the northeastern part of the Netherlands,for example. The city's central train station has underground parking for 10,000 bikes. Question: What does the Dutch government do about teenagers cycling? Options: A: It makes cycling covered by school education. B: It encourages teenagers to cycle alone. C: It will watch over teenagers who ride bikes. D: It suggests teenagers cycling before driving.

I'm taking a test and have to guess the right answer to the question after the article. 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: What impressed the author when she first moved into the house? Options: A: The tree house. B: The big trees. C: The cold floors. D: The green grass.
