The introduction of the iPad, with its touch screen technology, has allowed even very young children to take advantage of a computer. So what if all children in a school were given an iPad to use in class and take home with them?
Anne Laure Bazin works in a school where every child, teacher and teaching assistant is given a free iPad to use in and out of lessons. For her, the main advantage of everyone having an iPad had been the improvement in communication. Documents can be emailed straight over to workmates during a meeting. Children submit their homework by email, or through the school’s learning environment. Teachers now take the register（点名）using their iPad, which means that there is a record of which children are in school, and which classroom they are in.
The use of iPad has encouraged greater sharing of resources among teacher. All communication with parents is now done by email. Working as a group in class is much easier as children can share documents. The whole class can look at one child’s work by attaching（连接）the iPad to the whiteboard. If a child has forgotten the textbook, the teacher can take a photograph of the relevant（相关的）page and send it to the student in class.
While the use of the iPad in schools has revolutionized（变革）the way children are taught , it hasn’t completely replaced more traditional methods of teaching . Worksheets are still used in class as some children prefer the contact with paper. The children all have a textbook and exercise books. In Anne Laure’s school, parents feared that the iPads would replace exercise books and children would lose handwriting skills. Anne Laure says, “ The teacher are not ready to let go of the traditional style of teaching. We have welcomed the iPads in so much as they help communication and widen the resources available but we are not ready to let go of paper yet. The children themselves still value their exercise books and depend on them for review. ”
1 The underlined word “submit” in the second paragraph means________.
A. discuss B. share C. hand in D. send out
2 . What is an advantage of using iPads in the classroom?
A. It saved students bringing the textbooks.
B. It reduces parents’ worry about teaching.
C. It improves the relationship between teachers.
D. It makes it convenient to share information.
3 . What is parents’ attitude towards the use of iPads in the classroom?
A. Worried B. uncaring C. Annoyed D. Doubtful
4 . What is the main idea of the last paragraph?
A. Teachers prefer traditional methods of teaching.
B. The iPads won’t take the place of printed materials.
C. More and more schools are using iPads.
D. Exercise books are more valuable now.
B
The idea behind Facebook is to make us feel connected all the time. But in my research, I’ve found that the truth is quiet different.
Technology, it turns out, has made being alone seem like a problem that needs soling. When young people are alone, even for a minute or two, they feel the need to connect, to. get on Facebook or some other social networks and chat. But in connecting. they often end up feeling more isolated. Why? Because by being in constant(不断的) connection, they lose the ability to feel satisfied with their own company(独处).
Facebook can help us keep in touch with our friends, but we too often use it instead of spending face to face time with them. And since we feel the need to keep up with them online, we don't have moments of loneliness where we can collect our thoughts and learn how to be comfortable being alone.
-SherryTurkle. Profescer
Facebook connects more of us to more of our friends and family in more places than we have ever been connected before. Yes. Facebook is a huge time sink -maybe the biggest ever, Many people post useless stuff. And seeing too much of your friends lives can make you jealous (嫉妒的)，but it won't make you lonely.
Jane, a former student of mine, who is back in New York after living abroad for ten years told me that Facbook helps her a lot. The first time she moved back to New York from abroad, she felt disconnected from her family and friends. now because of lots of photos and information updates(更新), she knows what is happening with her friends all the time.
In fact, if you are lonely in real life, you will be lonely online as well.
---Sree Steniveasan, Chief Digital office
5. The underlined word "isolated” in Paragraph 2 means
A. free B. selfish C. careless D. lonely
6. According to Sherry Turkle, we should_________
A. feel satisfied with our life
B. avoid using social networks
C. keep in touch with our friends
D. enjoy moments of loneliness

What is eBay? The simple answer is that it is a global trading platform where nearly anyone can trade practically anything. People can sell and buy all kinds of products and goods, including cars, movies and DVDs. sporting goods, travel tickets, musical instrument clothes and shoes- the list goes on and on.
The idea came from Peter Omidyar, who was born in Paris and move to Washington when he was still a child. At high school, he became very interested in computer monogramming and after gradating from Tuft University in 1988, he worked for the next few years as a computer engineer. In his free time he started eBay as a kind of hobby, at first offering the service free by word of mouth.By1996 there was so much traffic on the website that he had to upgrade(升级)and he began charging a fee to members Joined by a friend, Peter Skoll, and in 1998 by his capable CEO, Meg Whitman,he has never looked back. Even in the crashes of the late 1990s, eBay has gone from strength to strength. It is now one of the ten most visited online shopping websites on the internet.

Electronic book publishing has many of the same risks and opportunities as electronic music publishing. By delivering text direct to the reader's computer screen, the e-book could cut down costs, and allow creators to deal directly with their audience, by passing（绕开）traditional publishers and traders. But it also raises the possibility of mass piracy（盗版）. Phil Rance, founder and managing director of Online Originals, a London-based e-book publisher, sums it up, "No one wants Napster（在线音乐服务）to happen to books."
Indeed, the most popular MP3may have put the frighteners on an industry that generally operates some way behind the"bleeding edge". The Meta Group, a leading US-based market researcher, says publishers are far too concerned about protecting their rights, "We believe all the recent legal control over Napster is like putting a finger in a river that is already overflowing. Publishers need to deal with reality and come up with new ways to develop wide electronic distribution, asking the question：How can we use the certainty of wide distribution to our advantage."
At the moment, most publishers would like to limit the use of e-books to the person who bought them, or to the computer used to download them. If that can be done, e-books become just an extra income stream in a publishing industry that would continue to operate the way it does today, according to Terry Robinson, business manager for Adobe's e-paper group. "If you've cracked the digital rights aspect, you've cracked the market. "He says.
Robert Nichols, Books Director at BOL agrees, "Rights management is absolutely important. Publishers just say that‘until copyright is secure, we are not going to talk'. "
5. According to the text, what is the similarity of e-books to electronic music
A. They both avoid industry management.
B. They both result in piracy.
C. They both bring in much money to creators.
D. They both lead to price reduction.
6. From the text, we can infer that?
A. wide use of e-books may increase the income
B. the publishing markets should be brought back to normal
C. publishers haven't agreed on rights management up to now
D. most publishers prefer e-books for the extra income
7. What do publishers care most about e-books?
A. Price. B. Copyright.
C. Quality. D. Design.
8. Which of the following can be the best title for this text?
A. The E-book-a New and Big Challenge
B. The E-book-an Extra Income Stream
C. An Economic Rise from E-books
D. Changes Brought by E-books
二、根据所给汉语及提示, 完成下列句子。
1. I'm trying to_____________________(解决问题), but I can't find the right solution
2. Alice overslept this morning.________________________(结果)she was late for work.
3. _________________(在某种程度上). I'm glad you made that mistake, for it’ll serve as a warning to you. (way)
4. I can't control what happens to me, but I can choose how I________________(处理)it.
