Electronic books have changed the way many people read for pleasure. Now online textbooks are changing the way some students learn and some teachers teach.

More than one hundred seventy-five thousand students attend the public schools in Fairfax County, Virginia, outside Washington. Last year, the school system used digital books in fifteen schools. This school year, middle schools and high schools changed from printed to electronic textbooks in their social studies classes.

Luke Rosa is a history teacher at Falls Church High School. His students work on laptop computers at school. He explains the idea to them this way. “I mean, it’s just like a regular textbook, except it’s got it all online.”

Peter Noonan, an assistant superintendent (助理监督) of schools, said, “The world’s changing. And the online textbooks can change right along with the events that are happening.” Digital books also cost less than printed textbooks, he said.

A student named Melanie Reuter said, “I don’t have to carry a textbook around, so that’s nice.”

But another student said, “I don’t like it because the Internet sometimes doesn’t work.”

Students also need access to the Internet when they are not at school. About ten percent of students in Fairfax Country do not have a computer or online access at home. Public libraries in the country have free Internet. There are also after-school computer labs as well as computer clubhouse supported by the country. Middle school student Slieman Hakim is happy about that. He said, “My family only has one computer; my sister and I both do our homework on it. So I come here to do my homework. It’s good.”

Other school systems in the area are also considering online textbooks.

Technology is forever changing the way we get our news. Many people now get a lot of their news on electronic devices, instead of traditional media, such as newspapers, television or radio. Now, there is a new way we get the news: computer-created news readers.

Recently, China's Xinhua launched (推出) the world's first AI news presenters with the Chinese search engine Sogou. The news readers created by machine learning technology are based on two real-life newsmen. One is able to present newscasts in English; the other, in Mandarin Chinese.

One Xinhua's report said machine learning was used to examine video images and sounds of the two newsmen, which look and sound like real people.

Some machine learning experts said the system showed off China's latest progress in voice recognition, text-to-speech technology and data analysis. But several experts suggested that the term AI does not correctly describe abilities of the robotic news readers.

On social media, many Chinese noted that the AI presenters did not seem real. People blamed them for not being more lifelike. Others wondered about the effects robots might have on employment and workers. Some people argued that only low-level jobs requiring heavy labor will be easily replaced by robots. Others praised the technology as a way for companies to make money from low-cost labor machines.

Some businesses have experimented with similar technology for possible use in news operations. Britain's BBC recently released a video that used machine learning to make it look like one of its news readers speaking different languages. The London-based company that developed the system says its goal is to "remove the language barrier" for many different kinds of video across the Internet.

1.What does the author intend to do in Paragraph 1?

A.Introduce the topic of the text.

B.Summarize the different opinions.

C.Add some data about the AI presenters.

D.Compare different ways of getting news

2.What is the machine learning technology used to do?

A.To keep AI presenters from making any mistakes.

B.To make AI presenters speak more fluently.

C.To ensure images and sounds are like real persons.

D.To bring newscasts up to date every hour.

3.What are some people worried about when AI presenters were launched?

A.Robots will eventually replace human all over.

B.Robots may threaten some people's employment.

C.Robots may endanger most people's health.

D.Robots will rule over the world in the end.

4.From the last paragraph we know that______.

A.BBC has removed the language barrier in newscasts

B.BBC's news readers can speak different languages

C.BBC shows interest in Xinhua's AI news presenters

D.BBC has done similar experiments as Xinhua does

Great changes have been taken place in the way people communicate with each other. In the past people write letters to share informations and later they talked with each other in the telephone. Now more and more people use our own mobile phones to communicating. And instead writing on the paper, they e-mail to each other on the computer. As a result, people find that quicker and easier to communicate, and at the same time some people feel that they become poorer in writing. They worry about whether people can be as closely as before

There have been many great inventions that changed the way we live. The first great invention was one that is still very important today—the wheel. This made it easier to carry heavy things and to travel long distances. For hundreds of years after that there were few inventions that had as much effect as the wheel. Then in the early 1800’s the world started to change. There was little unknown land left in the world. People did not have to explore much anymore. They began to work instead to make life better. In the second half of the 19th century many great inventions were made. Among them were the camera, the electric light and the radio. These all became a big part of our life today.

The first part of the 20th century saw more great inventions. The helicopter in 1909. Movies with sound in 1926. The computer in 1928. And jet planes in 1930. This was also a time when a new material was first made. Nylon came out in 1935. It changed the kind of clothes people wear. The middle part of the 20th century brought new ways to help people get over disease. They worked very well. They made people healthier and let them live longer lives. By the 1960’s most people could expect to live to be at least 60. By this time most people had a very good life.

Of course new inventions continued to be made. But man now had a desire to explore again. The world was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space. In 1969 man took his biggest step away from the earth. Americans first walked on the moon. This is certainly just a beginning, though.

New inventions will someday allow us to do things we have never yet dreamed of.

1.Why did the world start to change in the early 1800’s?

A.Because there were few inventions that had as much effect as the wheel for hundreds of years.

B.Because people began to work to make life better instead of exploring unknown world.

C.Because there was little unknown land left in the world.

D.Because people did not have to explore much anymore.

2.In Paragraph 2, the word “They” in the sentence “They worked very well” refers to ________.

A.helicopters, computers, jet planes, nylon B.new materials

C.new ways to help people get over disease D.people

3.Why did man have a desire to explore again?

A.Going into space is a dream for man to realize.

B.Man wanted to move to other stars.

C.Other countries wanted to follow Russia.

D.Other countries wanted to catch up with America.

Social networking sites like Facebook and Twitter have changed the way that people interact and connect on a daily basis. They are changing the face of relationships of every kind. One of the major concerns that have caught the attention of many, is the influence that social media may be having on social anxiety disorders.

If removed from their phone for a few hours or a few days, the average person would likely feel anxious about not being “connected”. Most people have probably experienced an occasion in which they posted a creative photo, and waited to see “how many” or “retweets” they received. If this number is lower than expected, the（自我）ego is going to take a hit. There is also constant checking of the number of “followers” and “friends” that you have, and these numbers can have a direct influence on feelings of acceptance and popularity.

Anxiety can arise from feeling at a loss when faced with too much going on at one time Multitasking can very quickly lead to increased levels of anxiety. Most people can likely relate to feeling the constant need to check their phone while driving, during meals or at work. This desire is actually leading to increased levels of anxiety. The choice to be constantly connected leads to the feeling of having to always make yourself available.

Social anxiety is much different from the anxiety one feels from being offline. It’s a more serious type of anxiety resulting from the fear of being judged by others while in a social interaction. Cases can range from mild--- and are often the cause of a lot of drinking with others to severe, in which case a person may avoid parties and get-togethers altogether.

The degree to which social media and technology are changing our lives and introducing new forms of anxiety is anything but deniable（可否认的）. The real question is to what extent are they introducing new disorders or increasing existing ones like social anxiety. It’s certainly a topic worth studying more to determine who is being helped, who is being harmed and how social anxiety can be dealt with.

1.What is the major focus of the text？

A.Human desire for social interaction.

B.The influence of social media on anxiety.

C.Anxiety resulting from interpersonal relationships.

D.The popularity of social media in people’s daily life.

2.How does the author explain social anxiety in Paragraph 2?

A.By giving examples. B.By offering statistics.

C.By providing processes. D.By making comparisons.

3.According to the author, which of the following can lead to increased levels of anxiety?

A.Not being available for get-togethers. B.Chatting on the phone with a friend.

C.Using the phone while driving. D.Eating meals alone.

4.What does the underlined word “they” in the last paragraph refer to?

A.Life changes. B.Anxiety degrees.

C.New forms of anxiety. D.Social media and technology.

Electronic book publishing has many of the same risks and opportunities as electronic music publishing. By delivering text directly to the reader's computer screen, the e-book could cut down costs, and allow creators to deal directly with their audience, bypassing 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 to happen to books.”

Indeed, the most popular MP3 may 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 change 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 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're not going to talk’．”

1.According to the text, what is the similarity of e-books to electronic music？

A.They both result in piracy.

B.They both lead to price reduction.

C.They both bring in much money to creators.

D.They both avoid industry management.

2.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.

3.What are most publishers concerned about according to the text?

A.copyrights management B.price control

C.market share D.original works

4.Which of the following can be the best title for the text?

A.A Magic Book

B.The Fight Against Mass Piracy

C.Risks and Challenges Go Hand in Hand

D.The E-book----a New and Big Challenge
