Last week, Education Secretary Arne Duncan declared a war on paper textbooks. “Over the next few years,” he said in a speech at the National Press Club, “textbooks should be abandoned.” In their place would come a variety of digital-learning technologies, like e-readers and multi-media websites.

Such technologies certainly have their place. But Secretary Duncan is threatening to light a fire to a tried-and-true technology—good old paper—that has been the foundation for one of the great educational systems on the planet. And while e-readers and multi-media may seem appealing, the idea of replacing an effective learning platform with a widely hyped (炒作) but still unproven one is extremely dangerous.

An expert on reading, Maryanne Wolf, has recently begun studying the effects of digital reading on learning, and so far the results are mixed. She worries that Internet reading, in particular, could be such a source of distractions(分散注意力) for the student that they may cancel out most other potential benefits of a web-linked, e-learning environment, and while it’s true that the high-tech industry has sponsored substantial amounts of research on the potential benefits of Web-based learning, not enough time has passed for longitudinal（縱向的） studies to demonstrate the full effects.

In addition, digital-reading advocates claim that lightweight e-books benefit students’ backs and save schools money. But the rolling backpack seems to have solved the weight problem, and the astounding costs to outfit every student with an e-reader, provide technical support and pay for regular software updates promise to make the e-textbook a very pricey choice.

As both a teacher who uses paper textbooks and a student of urban history, I can’t help but wonder what parallels exist between my own field and this sudden, wholesale abandonment of the technology of paper.

1.Which of the following statements is true according to the passage?

A. A tried and true technology is paper, long used in educational system.

B. Digital learning technologies will replace the paper textbooks sooner or later.

C. E-readers and multimedia websites are learning methods that are proved effective.

D. Multi-media websites and a good old paper are kinds of digital-learning technologies.

2.What are drawbacks of textbooks according to the passage?

A. Its price. B. Its weight. C. Its content. D. Its appearance.

3.What worries Maryanne Wolf is that ________.

A. paper learning can provide more potential benefits

B. the results of digital reading effects are understandable

C. students may not focus on learning by digital reading

D. digital reading can’t provide potential benefits for users

4.What is the author’s attitude towards digital-learning?

A. disapproving. B. supportive. C. positive. D. objective.

科目：高中英語 來源：2017屆重慶市高三下學期第一次月考英語試卷（解析版） 題型：閱讀理解

It was not until I was 9 years old that I found out my father was ill. It was 1994, but I can remember my mother's words as if it were yesterday: "Kernel, I don't want you to take food from your father, because he has AIDS. Be very careful when you are around him." AIDS wasn't something we talked about in my country when I was growing up. From then on, I knew that this would be a family secret. My parents were not together anymore, and my dad lived alone. For a while, he could take care of himself. But when I was 12, his condition worsened. My father's other children lived far away, so it fell to me to took after him.

We couldn't afford all the necessary medicine for him, and because Dad was unable to work, I had no money for school supplies and often couldn't even buy food for dinner. I would sit in class feeling completely lost, the teacher's words muffled as I tried to figure out how I was going to manage. I did not share my burden with anyone. I had seen people reacted to AIDS. Kids laughed at classmates who had parents with the disease. And even adults could be cruel. When my father was moved to the hospital, the nurses would leave his food on the bedside even though he was too weak to feed himself.

I had known that he was going to die, but after so many years of keeping his condition a secret, I was completely unprepared when he reached his final days. Sad and hopeless, I called a woman at the nonprofit National AIDS Support. That day, she kept me on the phone for hours. I was so lucky to find someone who cared. She saved my life.

I was 15 when my father died. He took his secret away with him, having never spoken about AIDS to anyone, even me. He didn't want to call attention to AIDS. I do.

1.What does Kernel tell us about her father?

A. He had stayed in the hospital since he fell ill.

B. He worked hard to pay for his medication.

C. He told no one about his disease.

D. He was carefully attended by the nurses on his deathbed

2.What can we learn from the underlined sentence?

A. Kernel found what the teacher said hard to understand.

B. Kernel had special difficulty in hearing.

C. Kernel was too tired to hear her teacher's words.

D. Kernel was too troubled to focus on the lesson.

3.Why did Kernel keep her father's disease a secret?

A. She wanted to obey her mother.

B. She was afraid of being looked down upon.

C. She found no one willing to listen to her.

D. She thought it was shameful to have AIDS.

4.What’s the author’s purpose in writing the text?

A. To tell people about the sufferings of her father

B. To prove how little people knew about AIDS.

C. To draw people’s attention to AIDS.

D. To recall a hard time of her childhood.
