2 . Your Internet experience makes you sad when the net speed is too slow. It takes so long to open a web page and the show that you’re watching stops every few minutes. That can be very annoying. But 5G can solve these problems. 5G technology is used widely now. What influence will 5G really have on our lives?

The “G” in “5G” means the generations of mobile network technologies. 1G let us talk to each other. 2G let us send messages. 3G gave us mobile data and the Internet, and 4G made all of these things faster. With 5G you can download an HD movie in seconds, send and receive data almost without stopping.

5G is able to improve many advanced technologies, such as driverless cars. With a 5G network, almost no stopping in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid dangers. At the same time VR games will become more popular with 5G because it can make games feel even more real.

Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not “travel” far. 5G will only cover about 300 meters. In order to use a 5G network we will have to buy new and expensive products only for 5G.

4 . In the future, people may travel to Mars by water﹣powered spaceship! Today’s spaceships are fine for getting things into space, but they are not so good at travelling long distances. These spaceships burn chemical fuels（化学燃料）and they are very expensive. Scientists say that a water-powered spaceship could make the trip to Mars much cheaper. The idea is just in the planning stages now, but scientists think such a spaceship could be developed soon.

The key to the water﹣powered spaceship is the engine（发动机）. Regular engines push spaceships by burning fuel. The water engine will use steam, created by solar panels that heat water to a high temperature. Of course, the spaceship will have to carry a lot of water for the long trip to Mars.

One US company has already developed a spaceship like this. These spaceships are made of a strong material. Two of them have already been sent up into space, using rockets and then later filled with air. “Balloon” spaceships could be very large and carry enough water for a long trip. With the “Balloon” spaceships, enough water could be carried to power the engines and grow food during the trip. And the people on the spaceship might even get to take a hot bath!

Scientists say the biggest advantage of such a spaceship would be its cost. The “Balloon” spaceship uses water to push it through space and costs about one thirtieth of a normal spaceship. Such savings naturally encourage continued research into balloon spaceships and water engines. If these scientists are correct, we may soon be on our way to Mars in a spaceship powered by water.

1. Which of the following statements is true? ________

A．Chinese scientists have developed the water﹣powered spaceships.	B．Scientists are thinking about developing water﹣powered spaceships
C．It takes people a lot less money to send today’s spaceships into space.	D．Fuels﹣burned spaceships are much cheaper than water﹣powered ones.

2. The water﹣powered spaceships have to carry lots of water ________.

A．to burn much water to make fuel	B．just to use plenty of water in space
C．to provide enough steam for the engine	D．to push spaceships to travel long distances

3. Astronauts use the rest of the water in the “Balloon” spaceships to do the following EXCEPT ________.

A．blowing up a balloon

B．growing something to eat

C．taking a hot bath

D．starting the engine

4. The underlined “it” in the last paragraph refers to（指代）________.

A．the planet Mars

B．water as “fuel”

C．the “Balloon” spaceship

D．a normal spaceship

5. What’s the main purpose of this passage? ________

A．To introduce the fuel used by different space ships.	B．To describe the advantages of the water﹣powered spaceship.
C．To let people know America has invented water﹣powered spaceships.	D．To tell us that humans may travel to Mars by water﹣powered spaceship

5 . 用方框中所给单词的适当形式填空，使短文完整、通顺。每词限用一次。

Have you ever seen a car without a driver? It sounds crazy, but these computer-driven driverless cars will soon be filling roads near you. Companies like Google and Tesla have been designing and     1     these cars, and the technology is there.

So how do they work? The cars have sensors (传感器) all around which can find other cars and     2     on the road. Sensors on the wheels also help when     3    , so the car knows how far it is from the stone or other parked cars. Road signs are read by cameras, and GPS is used so the car knows where you want to go. All you have to do is type in the address!     4    , a central computer system takes in all the information it receives from the sensors and cameras and work out when to speed up, turn and stop.

Sound     5     your idea of heaven? Sitting back, looking out of the windows and even watching a film or reading a book while “driving” would be     6     with this new technology. You wouldn’t have to worry about remembering directions where you’re going. In addition, computers are generally better     7     than humans. They would also drive     8     than people — they don’t listen to music or talk with friends, they would follow the speed limit and they have quicker reaction times if something bad happens.

However, there are many downsides of driverless cars. Computers would have difficulty     9     ethical(道德的) decisions; if a child ran into the road, would the computer choose to hit the child or turn suddenly and kill the car’s passengers? There would also be many legal decisions to be made — should children, or drunk people, be allowed in a driverless car by     10    ? Or would there need to be a responsible(有责任的) adult with a driver’s licence in the car at all times?

6 . The Internet joins millions of computers all over the world, and today it is used by people all over the world. It was invented in the 1960s in the USA. The American government needed a network of computers for its army. Then in the 1970s scientists and business people also wanted to use the Internet to send and receive messages. For some years, they weren’t allowed to use the US network, and when they were allowed to, the messages were in very simple text without photos.

The World Wide Web was invented by a British scientist named Tim Berners-Lee in 1989. He wanted to send documents to other scientists, so he developed the World Wide Web. This allowed him to send and receive scientific documents with text, drawings and photos(also called multimedia documents). In the 1990s, more and more people began to use the Internet and the World Wide Web.

So what’s the difference between the Internet and the World Wide Web?The Internet is the hardware. It allows us to communicate with other people. The World Wide Web is the software. It allows us to create, see and read multimedia documents.

The Web is made up of millions of documents called Web pages. These pages are held in computers all over the world. Many people have a favorite website with a number of Web pages on the same subject.

The email is a way of using your computer to send and receive messages. It’s cheaper and quicker to use emails than send normal mails. New users call the normal mail “snail mail” because it’s too slow. It took 50 years for 100 million people to listen to the radio. It took 15 years for 100 million people to watch television. By the year 2000, it had taken only about three years for 100 million people to use the Internet. What will happen next on the Internet?

1. The Internet was first invented for _________.

A．scientific work

B．the American army

C．business people

D．the American government

2. The World Wide Web was invented to ________.

A．communicate with others	B．create,see and read documents

8 . “Life is speeding up. Everyone is getting unwell.”

This may sound like something someone would say today. But in fact, an unknown person who lived in Rome in AD(公元) 53 wrote it.

We all love new inventions. They are exciting, amazing and can even change our lives. But have all these developments really improved the quality of our lives?

Picture this. You’re rushing to finish your homework on the computer. Your mobile phone rings, a QQ message from your friend appears on the screen, the noise from the television is getting louder and louder. Suddenly the computer goes blank and you lose all your work. Now you have to stay up all night to get it done. How happy do you feel?

Inventions have speeded up our lives so much that they often leave up feeling stressed and tired. Why do you think people who live far away from noisy cities, who have no telephones, no cars, not even any electricity often seem to be happier? Perhaps because they live simpler lives.

One family in the UK went “back in time” to see what life was like without all the inventions we have today. The grandparents, with their daughter, and grandsons Benjamin, 10 and Thomas, 7, spent nine weeks in a 1940s house. They had no washing machine, microwave(微波炉), computer or mobile phones.

The grandmother, Lyn, said, “The more things you have, the more difficult life becomes.” The boys said they fought less. Probably, they said, because there was less to fight over, such as their computer. Benjamin also noticed that his grandmother had changed from being a “trendy(赶时髦的), beer-drinking granny”, to one who cooked things.

10 . A Letter from Mars

Dear Earthmen,

I have enjoyed my stay on your interesting planet.

I think I understand the life on the earth now and I would like to give my impressions(印象).

First of all, you live in boxes. Every morning you leave your big boxes and get into smaller boxes on wheels(轮子). All these small boxes run around and around, and finally stop to rest. You leave these boxes on wheels and go to very large tall boxes.

After resting all day, you get back in your little boxes and return to your big boxes. There you sit and look at every small glowing(闪闪发光的) boxes with moving pictures on the front.

There is only one thing I don’t understand. I went to a football game one day. A group of angry boys fought a little round ball. Everyone shouted but they kept fighting. They were angry, because they had been kept in boxes all day. I think.

Thank you earthmen for this chance to get to know you.

Yours,

The man from Mars
