Read the article and select the best answer. Article: The average college student in America spent an estimated seven hundred dollars on textbooks last year. The National Association of College Stores reported more than five billion dollars in sales of textbooks and course materials. Association spokesman Charles Schmidt says electronic textbooks now represent just two to three percent of sales. But he says that is expected to reach ten to fifteen percent by 2012. Online versions are now available for many of the most popular college textbooks. E-textbooks can cost half the price of a new print textbook. But students usually lose access after the end of the term. And the books cannot be placed on more than one device so they are not easy to share. So what do students think of e-textbooks? Administrators at Northwest Missouri State University wanted to find out. Earlier this year they tested them with five hundred students in twenty classes. The university is unusual. It not only provides laptop computers to all seven thousand of its full-time students. It does not require students to buy their textbooks either. They rent them to save money. The school aims to save even more by moving to e-textbooks. The students in the survey reported that downloading the books from the Internet was easy. They liked the idea of carrying lighter backpacks. And fifty-six percent said they were better able to find information. But most found that using e-textbooks did not change their study habits. And sixty percent felt they read more when they were reading on paper. In all, almost half the students said they still liked physical textbooks better. But the survey found that cost could be a big influence. Fifty-five percent said they would choose e-textbooks if using them meant their textbook rental fee would not increase. Roger Von Holzen heads the Center for Information Technology in Education at Northwest Missouri State. He tells us that administrators are disappointed with the e-textbooks now available because the majority are not interactive. He thinks growth will come when... Question: The passage mainly tells us about _ . Options: A: the development of e-textbooks B: different attitudes towards e-textbooks C: the sales of textbooks and course materials D: the differences between e-textbooks and physical text-books

Read the article and select the best answer. Article: A cactus stood all alone in the desert, wondering why it was stuck in the middle of nowhere."I do nothing but stand here all day," it sighed."What use am I? I'm the ugliest plant in the desert.My spines are thick and prickly , my leaves are rubbery and tough, I can't offer shade or juicy fruit to any passing traveler.I don't see that I'm any use at all." All it did was stand in the sun day after day, growing taller and fatter.Its spines grew longer and its leaves tougher...It truly was strange-looking. "I wish I could do something useful," it sighed.By day, hawks circled high overhead."What can I do with my life?" the cactus called.Whether they heard or not, the hawks sailed away.At night, the moon floated into the sky and cast its pale glow on the desert floor."What good can 1 do with my life?" the cactus Called: The moon only stared coldly as it goes on its way.A lizard crawled by, leaving a little trail in the sand with its tail."What worthy thing can I do?" the cactus called."You?" the lizard laughed, pausing a moment."Worthy deed? Why, you can't do anything! The hawks circle ways overhead, tracing delicate patterns for us all to admire.The moon hangs high like a lantern at night, so we can see our way home.Even I, the lowly lizard can decorate the sands with these beautiful brush-drawings as I pull my tail along.But you do nothing but get uglier every day." And so it went on year after year.At last the cactus grew old, and it knew its time was short."Oh, God" it cried out, "I've wondered so long, and I've tried so hard.Forgive me if I've failed to find something worthy to do." But just then the cactus felt a strange stirring and unfolding.At its very tip, like a sudden crown, a glorious flower suddenly opened in bloom. Never had the desert known such a blossom.Its fragrance perfumed the air far and wide and brought happiness to all passing by. The butterflies paused to admire its beauty, and even the moon smiled when it rose to find such a treasure.The cactus heard a voice."You have waited long,"... Question: What attitude should lonely ordinary people have in our life? Options: A: Aiming high and do admirable things like hawks. B: Learning from the cactus to be worried and ashamed of itself. C: Acting as the lizard to be proud of itself and look down upon others. D: Having a heart that seeks to do good and never gives up.

Ques:Read the article and select the best answer. Article: In a great many cities, hundreds of people ride bicycles to work every day. In New York City, some bike riders have even formed a group called Bike for a Better City. They declare that if more people rode bicycles to work, there would be fewer automobiles in the downtown part of the city and so less dirty air from car engines. For several years this group has been trying to get the city government to help bicycle riders. For example. They want the city to draw special lanes for bicycles only on some of the main streets, because when bicycle riders must use the same lanes as cars, there are accidents. Bike for a Better City feels that if there were special lanes, more people would use bikes. But no bicycle lanes have been drawn. Not everyone thinks it is a good idea-they say it will slow the traffic. Some store owners on the main streets don't like the idea-they say that if there is less traffic, they will have less business. The city government has not yet decided what to do. It wants to keep everyone happy. On weekends, Central Park-the largest place of open ground in New York-is closed to cars, and the roads may be used by bicycles only. But Bike for a Better City says that this is not enough and keeps fighting to get bicycle lanes downtown. Question: In New York, a group of bike riders _ . Options: A: are keeping practicing for health B: have no cars of their own C: are complaining there are not enough buses D: are trying to settle the problem of air pollution
