Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of 19.42 Mbps. But by comparison 5G promises gigabit (千兆) speeds.

“5G is one of those signs, along with artificial intelligence, of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基础设施) construction. There’s lots of data behind that task, which is why we need high speed.

Augmented reality glasses and virtual headset haven’t yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.

Ericsson stated at February’s Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.

But don’t get too excited. There’s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn’t concentrated only in big cities.

1.What does the author want to stress in Paragraph 1?

A.The lighting-fast speed of 5G.

B.The expectation of 5G world.

C.The difference between 4G and 5G.

D.The internet-connected devices in our life.

2.What does the underlined word “emblem” in Paragraph 2 mean?

A.Exhibition. B.Success.

C.Symbol. D.Explanation.

3.We can infer from the text that ________.

A.5G world won’t come without AR glasses

B.5G helps to create the artificial intelligence vehicle

C.Apple company is developing AR glasses worldwide

D.Tech companies will face the fact that smartphones may be replaced

4.What will the author probably tell us next?

A.How to fully expand 5G coverage.

B.Smart glasses will become faster and lighter.

C.Why 5G isn’t concentrated in big cities.

D.The importance of infrastructure construction.

An American spacecraft is moving closer to a dwarf planet(矮行星)called Ceres(谷神星). The American space agency's Dawn spacecraft is set to reach the planet-like object in March.

Space agency scientists will then place Dawn in an orbit(轨道) around the dwarf planet. Agency scientists want to know more about ice on Ceres. The spacecraft will gather clues about whether Ceres may have once had conditions to support life as we know it.

Dawn left Earth more than seven years ago on a trip to explore Ceres and another dwarf planet, called Vesta(灶神星). Both dwarf planets are in the main belt of asteroids(小行星), a group of large objects, between the planets Mars and Jupiter.

Marc Rayman is the chief engineer and director of the Dawn mission.

Scientists call Vesta and Ceres "protoplanets(行星) ". Mr. Rayman says they were in the process of becoming full-size planets when, in his words, "their growth was terminated(终止)."

Scientists believe Ceres is made of rock, and covered with ice.

The Dawn mission is based in Los Angeles, California. Scientists there send second-by-second commands to the spacecraft. They direct its every move, including telling it what pictures to take. Dawn will make a map of the dwarf planet. It will also try to discover how Ceres' surface has changed.

Carol Raymond is the deputy principal investigator(副首席研究员) of the project. He says Dawn made an unexpected discovery while orbiting Vesta.

"Instead of being bone dry, which we expected, there were patches on the surface of Vesta that showed significant amounts of water bound in the rocks and possibly even free water that could have flowed on the surface in the past."

She says that if Earth's water came from wet worlds like Vesta and Ceres, then life could have developed there, too.

If Dawn finds that the environment of Ceres could have supported life, scientists may seek to explore the dwarf planet with other scientific instruments.

Dawn will gather information about Ceres until the middle of 2016. It will then continue to orbit the small planet.

1.Which of the following about spacecraft Dawn is true?

A. It was sent into space in 2008.

B.　 It is orbiting around the dwarf planet Ceres.

C.　 Its destination is just the dwarf planet Ceres.

D.　 It will gather information about Ceres until early 2016.

2.What’s the meaning of the underlined word “patches”?

A. spots　　　 B. roles　　　 C. sorts　　　 D.　 kinds

3.What do we know about Vesta?

A.　 It is in the main belt of asteroids between the planets Mars and Venus.

B.　 It is another dwarf planet which Dawn will explore.

C.　 It is becoming a full-size planet.

D.　 It is made of rock, and covered with ice.

4.The passage mainly tells us ______.

A.　 Spacecraft , Dawn, is researching Ceres.

B.　 What Spacecraft , Dawn,　 is.

C. NASA Spacecraft, Dawn, is moving closer to a 'Dwarf Planet'.

D. How Dwarf Planet research program is carried out.
