第一节(共10小题；每小题2.5分，满分25分)
A
When third and fourth graders in Cheryl Barber's class at Helena Flats Montessori School write stories about plants, they're not using pencils and paper, but rather iPads to take photos and type text.Nine?year?old Jenna Oilar held an iPad up to a bamboo plant.At the touch of the screen she took a photo.With her index finger and thumb she then changed it to fit a page in her group's book.Under the photo she typed in text.
Students can use many free apps(应用程序), uploaded by their teacher, to help learning.The apps offer a wide educational games suitable for learning.
To teach fluently, Barber plans to have students record themselves' reading.There are also advantages in using tablets with students who have disabilities or are learning a second language.Students can enlarge text, change fonts(字体), translate text to a different language or use audio to read text.
Using mobile technology isn't new to Barber's classroom.Before the iPads, her students used laptops and the iPod touch.The apps don't work to students who are learning to count money, tell time, solve maths problems and spell as they will get immediate feedback if they are doing a problem incorrectly.
Rather than traditional flashcards, Alex Puhl, 8, enjoys playing the game “Math Ninja” where he fights a robotic army by solving maths problems that pop up on the screen.
Students can only use games loaded by their teachers.The iPads also show a user's history—when a student starts or stops a program.Student scores are e?mailed directly to Barber.
Is third grade too early to introduce so much technology? Barber doesn't think so.
“By 2015, third grade is expected to type a story all in one setting，” Barber said.
What hasn't changed is that teachers still teach required curriculum(课程)．There still are pencils at desks, notebook paper, and yes, teachers' lectures and worksheets to fill out by hand.
1．What can we conclude from the passage?
A．The iPad is a real game changer in class.
B．The iPad has side effects on students.
C．The iPad brings convenience to teachers.
D．The iPad is the cause of students' failure.

B．She was playing a computer game attentively.

D．She was typing a letter to her parents.
3．The benefits of iPads for students are that ________．
A．they are free and programmed with funny games
B．they are also suitable for children with disabilities
C．they are timely uploaded by the school teachers
D．they are only intended for learning languages
B
Computer technology is still developing rapidly.The computer of the future will increase in value and performance while decrease in cost.It will become smaller, but faster and more powerful.
It is possible to make some guesses about what the future of the computer will look like, based upon the types of technologies that are being developed now.A lot of progress has already been made in some of these new technologies, but some are still in their earliest stages and may not be ready for use for years.Two of the most interesting areas of computing that are currently being developed are quantum computing(量子计算) and nanotechnology(纳米技术)．
Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today.Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many statistics at the same time.
Nanotechnology could also change the face of computing, by creating computers that could be very powerful, though they are tiny in size.These computers could be incorporated(并入) into everyday objects, including electrical appliances(电器), clothes and even the human body.We will be able to use computers in new and unimaginable ways.They will become a part of our lives rather than simply being a box that is used only for specific purposes such as work.
Quantum computing and nanotechnology will be able to play new roles, which will make us live greener lives, as well as enjoy better health and happier lives.
4．According to the text, quantum computing ________．
A．has been put in use so far
B．can make computers run by themselves
C．can reduce the cost of computers
D．will work by using transistors
5．The text is mainly about ________．
A．what nanotechnology is
B．what quantum computing is
C．what the computer of the future is like
D．what future computers can bring us
6．Which of the following best shows the structure of the text?
(①＝Paragraph 1, ②＝Paragraph 2，…⑤＝Paragraph 5)
A. B.
C. D.

C

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
The Internet has opened up a whole new online world for us to meet, chat and go where we have never been before.But just as in face?to?face communication, there are some rules of behaviour that should be followed when you are online. __11__ Imagine how you'd feel if you were in the other person's shoes.
For anything you're about to send, ask yourself, “Would I say this to the person's face？” If the answer is no, rewrite and reread. __12__
If someone in the chat room is rude to you, your instinct(本能) is to fire back in the same manner.But try not to do so. __13__ If it is caused by a disagreement with another member, try to fix the situation by politely discussing it.Remember to respect the beliefs and opinions of others in the chat room.
__14__ Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate.When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it.If it's a small mistake, you may not need to say anything.Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you the permission to correct everyone else. __15__ At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended(冒犯)．
It is not polite to ask others' personal questions such as their age, sex and marital status(婚姻状况)．Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions.
A．Everyone was new to the network once.
B．If you do decide to tell someone about a mistake, point it out politely.
C．It's natural that there are some people who speak rudely or make mistakes online.
D．The basic rule is simple: treat others in the same way you would want to be treated.
E．You should either ignore the person, or use your chat software to block his messages.
F．When you send short messages to a person online, you must say something beautiful to hear.
G．Repeat the process till you feel sure that you'd feel comfortable saying the words to the person's face.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
Circumstances__brought__us__together. One afternoon, I drove to film the last part of Paul__Young__who wrote the surprise best?seller The__Shack. We pulled up in front of a modest house on a quiet street about 20 minutes from my home. A familiar feeling went through me. I knew this house.
Six years ago I had driven to a house that looked very much like this one, on a far different mission. After years of struggle, my family had been freed from want, so I wanted to find some way to pass our blessings along.
Christmas was coming. The local paper was full of stories of people struggling to support their families. “We could donate to a charity，” my wife, Julie,__suggested. But I wanted to do something more directly. I wanted to find one husband, one father, to help. I'd slip one__hundred__dollars under his door. Julie was all for it.
A few days later, a friend told me about a family of eight that was just about to break. The husband was working three jobs trying to keep his house warm and his kids fed. That sounded perfect. I knew what it felt like to disappoint your family on Christmas. I asked my__friend for the address. He gave it to me, and then said, “His name is…”
“No, don't tell me，” I said. “I don't want to know his__name any more than I want him to know mine.”
The next morning I drove to the man's house, checked to see that no one was looking and slipped a__white__envelope__containing__five__twenty?dollar__bills__under__his__door. I walked back to my car and drove away unseen. Merry Christmas! I thought. I hadn't thought of the man and his family since then and till now.
We walked up the pathway to the house. Paul was standing there on the porch, waiting for us. A part of me wanted to tell him the__truth. But I stopped. I set up my camera on the porch. We filmed for 15 minutes: then Paul and I chatted. My curiosity finally got the best of me. I had to know. This was my last__chance.

I deeply appreciate your kindness in helping me like that.” Hearing what he said, I felt very surprised. Did I say circumstances brought us together? I couldn't wait to get home and tell Julie and my__friend about that. (142 words)
