The Internet has changed the world we live in dramatically, so that in some ways it is unrecognizable from the place we lived in twenty years ago. Communications have been revolutionized. Not only have cell phones found their way into most people’s pockets or purses, but they are also used for next messaging and as cameras. Long distance phone calls have been replaced by e-mail and video conferencing. Communications, person to person or company to company, have turned into a fast-paced exchange with instant response. In fact, it has become more convenient and efficient.

The other kind of communication the Internet provides is information. School children and medical researchers alike will tell you that they could not work without the Internet and its ability to connect them to any number of websites and databases of information. Many people do their banking on-line. Others plan a trip and book a flight for themselves. People do their own stock  trading through the Net. Sports fans follow scores and statistics on websites. Political junkies(政治狂) gather campaign statements and debate topics, even between elections. And almost everyone who owns a computer and has Internet access has bought at least one item on-line. No wonder some young people can not imagine what life was like before the Internet.

This time, it is to be worn on wrists. Having already changed the way we communicate with its smartphones, Apple Inc released its next big thing on March 9 in San Francisco, US.

The Apple Watch, according to CNN, is “a simple rectangular (矩形的) shape with a range of stylish and useful wristbands.” “The style is classic... in those respects (方面) it’s up there with the top quality Swiss watches,” commented the news outlet.

The watch will be available in nine places, including the US, the UK and China, from April 24. The starting price is $349 (2,186 yuan).

With six different designs and 30 or so wristbands, the gadget “sets the standard for smartwatches, in style,” agreed The Brisbane Times,“but more importantly, in functionality (功能性).” “With the built-in speaker and microphone, you can receive calls on your watch. I have been wanting to do this since I was 5 years old,” said Apple’s chief executive Tim Cook.

In fact, anything you can do on the iPhone is there on the watch – e-mails, text messages, airline boarding services, and directions from Apple Maps. Using a home security app, you can keep an eye on your home from afar, or even open a locked door.

There are some features that have made Cook sure the watch is “our most personal device yet; a new chapter in the way we relate to technology”. According to NPR, the watch taps you on the wrist to draw your attention to a message or a calendar reminder, and it can send a tap on the wrist to another Apple Watch wearer.

However, the watch can also do things that are just plain fun. You can send a real-time display of your heartbeat to another Apple Watch to “let someone know you are thinking about them.”

Patrick Moorhead, a leading technology analyst in the US, described the tech company as “a master in the art of persuasion”. “The secret weapon is the ability to message each other by tapping on the watch,” he told The Associated Press. “I think people, particularly kids, are going to go nuts (疯狂) over that.”

So far, though, the most impressive part of this new device is “the monitoring of the wearer’s health and fitness,” said AFP. It will even tap you on the wrist if you have been sitting down for longer than is good for your health.

1.Which of the following features of the Apple Watch are mentioned in the article?

a. its price

b. its functions

c. its shortcomings

d. its shape and weight

e. when and where people can buy it

A. abd

B. abe

C. bce

D. bde

2.Which of the following words best describes Tim Cook’s attitude toward the Apple Watch?

A. Proud.

B. Modest.

C. Serious.

D. Cautious.

3.How does the Apple Watch let wearers know there is a new message?

A. The watch beeps.

B. The watch sends out music.

C. The watch changes its screen color.

D. The watch taps the wearer on the wrist.

4.With an Apple Watch, you can ______.

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.

Philo Farnsworth is not a name most people know. But his work changed the way we learn, the way we live, and even the way we think. Philo Farnsworth is responsible for one of the 20th century: television.

Philo Farnsworth was born in America in 1906. He was interested in science and technology at an early age. When he was twelve years old, he built an electric motor for his family’s washing machine. When he was fourteen, he was already giving a lot of thought to electrons（电子）. As he was driving the family’s horse-drawn plowing machine, he noticed the evenly spaced rows of the potato fields. This sight gave him the idea that electrons could scan（扫描） an image one row at a time—an idea that was the key to electronic television.

By the time he was twenty-one years old, Farnsworth had started his own company and had managed to build the world’s first electronic television. It was a very simple device（设备）. But after years of hard work, Farnsworth was able to introduce the kind of television we now use.

Farnsworth was a great inventor, but lived an unhappy life. He had a legal battle with the company, Radio Corporation of America (RCA) over who the real inventor of the TV was. He won the case, but the government stopped companies from making TVs during the war, so Farnsworth didn’t make much money from the invention.

When Farnsworth was young, he imagined television as a convenient way for distant audiences to enjoy lectures by famous professors, or entertainment by the best symphonies（交响乐） and ballets. When he was older, television became much more popular, but he was very disappointed in the silly programs on TV. He even told his own son, “There’s nothing on it worthwhile, and we’re not going to watch it in this household.”

1.What can we learn about Philo Farnsworth?

A. He had a strong physical advantage.

B. He had strong powers of observation.

C. He had a strong interest in journalism.

D. He had a strong sense of responsibility.

2.The underlined sentence showed Farnsworth was legally recognized as ________.

A. the real founder of RCA

B. the real inventor of the TV

C. the greatest inventor of his time

D. the organizer of the battle with RCA

3.The last paragraph mainly tells us that Farnsworth ________.

A. didn’t like to watch TV programs

B. couldn’t afford to buy a TV set

C. couldn’t listen to famous lectures

D. didn’t like what television became

4.What is the best title for the text?

A. How did Philo Farnsworth invent television?

B. What caused Philo Farnsworth to invent television?

C. Philo Farnsworth: the unhappy father of television

D. Philo Farnsworth: a well-known scientist and inventor

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
