Net Library is a library that lends out digital books. It treats a digital book like a paperback copy. It charges libraries per book per copy and gives publishers a cut of the total income.

From the consumer’s point of view, this means that if more than five people want the latest Danielle Steel romance novel, other people who request that book will get a message saying the title is unable to get.

Many publishers seem to have embraced its model. More than 350 publishers gave the company rights to hand out their digital works, and McGraw-Hill Corporation and Houghton Mifflin Corporation have put money into the company. The California public libraries and about 1,800 others across the US are trying out the Net Library service.

Some librarians criticize the Net Library model. Stanford University librarian Michael Keller argues that the company is creating an unnatural fear of digital works, which is contrary to the ideas of the Internet.

Keller and some other librarians argue for the e-book vision set forth by Brary. Brary is starting a service that lets us users read books for free.

But it will charge about 25 cents a page when a person tries to point out material or copy and taste it into a different file or tries to download a copy onto a computer.

Christopher Warnock, chief executive of Brary, believes most consumers won’t want to buy entire books, only the parts that interest them.

“There is not really a lot of good owning an electronic file and having to store it and manage it. It doesn’t make sense,” he said.

1.How do publishers get money from the Net Library?

A.They get money from selling their books to the Net Library

B.They get money from the readers.

C.They get money by cutting the cost of the books.

D.They share the money with Net Library.

2.The underlined word “embraced” in the third paragraph means

A. tried out something hard

B. held something tightly

C. disliked something badly

D. taken something willingly

3.What does the last paragraph mean?

A. Net Library is not a good way for the consumers.

B. There is no need for consumers to have a whole book.

C. Brary is not a good library for the consumers.

D. It’s reasonable to charge the consumers money for copying some pages.

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest.

Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes(纬度). To achieve giant size, a tree needs three things: the right place to establish its seeding, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees.

In some parts of the world, populations of big trees are dwindling because their seedings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear.

Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. “During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic(新陈代谢的)rate increases,” explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth.

The Clarks’ theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions.

Besides, big trees face threats from elsewhere.

1. All the following factors are a must for making big trees EXCEPT_________.

A. genetic contribution

B. no deadly damage

C. ideal environment for growth

D. right place to establish its seeding

2.The word “dwindling”(paragraph3) is closest in meaning to “_______”.

A. exploding B. decreasing

C. changing D. growing

3. What is the best title of the passage?

A. Results of big trees’ disappearing.

B. Advantage of big trees.

C. Big trees in trouble

D. Importance of big trees to humans.

4.What will the author most probably discuss after the last paragraph?

A. Comparison between common trees and big ones.

B. The effect of human activities on big trees.

C. Benefits of big trees to the whole atmosphere.

D. More threats to the existence of big trees.

根据内容, 从对话后的选项中选出能填入空白处的最佳选项,选项中有两项多余选项。

It doesn't come as a surprise to you to realize that it makes no difference what you read or study if you can't remember it.You just waste your valuable time.1.One dependable aid that does help you remember what you study is to have a specific purpose or reason for reading.

Why does a clerk in a store go away when your reply to her offer to help is, "No, thank you.I'm just looking."? Both you and she know that if you aren't sure what you want, you are not likely to find it.But suppose you say instead, "Yes, thank you.I want a pair of sun glasses." She says, "Right this way, please."

2.If you choose a book, "just looking" for nothing in particular, you are likely to get just that—nothing.But if you do know what you want, you are almost sure to get it.Your reasons will vary; they will include reading or studying "to find out more about", "to understand the reasons for" and "to find out how".

3.Before you start to study, you say to yourself something like this, "I want to know why Stephen Vincent Benet happened to write about America".Because you know why you are reading or studying, you relate the information to your purpose and remember it better.

4.At least two important processes go on at the same time.As you read, you take in ideas rapidly and accurately.But at the same time you express your own ideas to yourself as you react to what you read.You have a kind of mental conversation with the author.

This additional process of thinking about what you read includes evaluating it, relating it to what you already know, and using it for your own purposes. 5.One part of critical reading, as you have discovered, is distinguishing between facts and opinions.Facts can be checked by evidence, Opinions are one's own personal reactions.Another part of critical reading is judging sources.Still another part is drawing accurate inferences.

A.This is the way it works.

B.Maybe you have already discovered some clever ways to keep yourself from forgetting.

C.It is important for students to have a positive attitude to their study.

D.You remember better when you know what you' re reading.

E.In other words, a good reader is a critical reader.

F.It’s quite the same with your studying.

G.Reading is not one single activity.

A Special Appointment

Years ago I moved to Woodland Hills to take a job in a small hospital’s emergency department. No one wanted to work on Christmas Eve, so the shift (轮班) went to me. I kissed my family goodbye and went off to spend the night in the hospital. It was a thankless job.

At 9 pm, the ambulance brought in a man in his 60s who was having a heart attack. His face was pale, and he was frightened. The whole night I did my best to save his life. Before I left in the morning to spend Christmas with my family, I stopped by to see how he was doing. It was still tough, but he had survived the night and was sleeping.

The following year I got Christmas Eve duty again. At 9 pm sharp, the ward clerk told me there was a couple who wanted to speak with me. When I approached them, the man introduced himself as Mr. Lee and said, “You probably don’t remember me, but last Christmas Eve you saved my life. Thank you for the year you gave me.” He and his wife hugged me, handed me a small gift, and left.

The following year a new doctor had joined the group, but I wanted to see if Mr. and Mrs. Lee would return. This time, I volunteered for the shift. I kept an eye on the door. Once again, at exactly 9 pm, the Lees appeared, carrying a warmly wrapped bundle. It was their new grandchild. Mr. Lee, his family and I spent 13 Christmas Eves together. In the later years the staff all knew about the story and would work to give me time with him in the break room, where we spent a half-hour each Christmas Eve.

The last year I saw him, he brought me a gift. I carefully opened the package and found a crystal (水晶) bell inside. It was engraved (镌刻) with a single word: Friendship. Now, my family, friends and I ring that bell every Christmas Eve at exactly 9 pm and offer our best wishes to the man who we won’t forget.

1.Working on Christmas Eve was considered “a thankless job” because ______.

A. most patients were seriously ill

B. patients refused to express thanks

C. doctors had nothing to do on that day

D. doctors couldn’t get praise for the hard job

2.When the author left the hospital the next morning, Mr. Lee ______.

A. was still in a state of danger

B. was really angry with her

C. got ready to leave the hospital

D. recovered from his heart attack

3.According to the passage, the author formed a habit of ______.

A. celebrating Christmas Eve with her family

B. giving Christmas gifts to the hospital staff

C. spending Christmas Eve with Mr. Lee in hospital

D. ringing the bell for patients in the emergency department

4.Why does the author ring the bell on Christmas Eve?

A. To honor her working experience.

B. To tell kids the traditional custom.

C. To remember an old friend of hers.

D. To show the beginning of the holiday.

BEIJING — Rising smartphone star Xiaomi is moving upmarket and taking aim at Apple's iPhone. The Chinese maker known for low-priced phones on Thursday unveiled (发布) a new model that Chairman Jun Lei said is comparable to Apple's iPhone 6 but thinner, lighter and much cheaper. The phone starts at 2, 299 yuan ($375), less than half the 5,288 yuan ($ 865) price of an iPhone 6 in China.

Xiaomi, founded in 2010, passed South Korea's Samsung Electronics Co. in the second quarter of last year as the best-selling smartphone brand in China by number of phones sold. The company is expanding into India and other developing markets but has yet to announce plans to enter the United States or Europe.

Xiaomi "is a respected brand that already has an Apple-like following" in China, said analyst Brian Blair, who tracks mobile device makers at Rosenblatt Securities. Apple is still a relatively small player in China, selling about 45 million iPhones there last year, Blair estimates, but will continue to grow.

"Apple is very much a premium (高端的) brand," said Blair. "The company that's more at risk is Samsung, which has been losing share in that market."

Privately held (私人控股的) Xiaomi said last year's sales tripled to 61. 1 million phones and revenue (收益) more than doubled to 74. 3 billion yuan ($12.2 billion). The company, based in Beijing, recently completed a round of fundraising from investors that it said valued Xiaomi at $ 45 billion, making it one of the world's most valuable technology brands.

Xiaomi ran into legal trouble in India in December after a court blocked sales while it hears a complaint by Sweden's LM Ericcson that the Chinese company violated its patents(专利).

In a blog post earlier this month, Lei called the case a "rite of passage" (成年礼) for a young company.

1.Which of the following statements is true?

A. Xiaomi sold more cellphones than Samsung in 2010 in China.

B. Compared to Xiaomi, Apple's iPhone 6 is thinner and lighter.

C. Low-price is Xiaomi's advantage over Apple's iPhones.

D. The company is expanding into the United States or Europe.

2.What can be inferred from the passage according to Brian Blair?

A. More than 45 million iPhones will be sold this year.

B. Xiaomi can beat Apple in the market of China.

C. He thinks Xiaomi is superior to Apple.

D. Samsung will be closed for losing share in the market.

3.How is the 5th paragraph developed?

A. By giving examples.

B. By analyzing cause and effect.

C. By providing data.

D. By making comparisons.

4.What's the attitude of Jun Lei towards the case of Xiaomi in India?

A. Negative. B. Satisfied.

C. Positive. D. Doubtful.
