    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 lightning-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.

二、语法填空

答案：touched; extremely; where; interest; than; to find; means; is constructed; much; its
解析：本文为说明文。主题语境为人与自然。主题语境内容为宇宙奥秘探索。文章主要讲述了中国发射的嫦娥四号无人探测器在月球背面成功着陆的重大事件。本文旨在激发学生的国家认同感和民族自豪感。

①考查时态。根据时间状语last week可知设空处需用一般过去时,故填touched。

②考查副词。设空处作状语,修饰形容词challenging,需用副词形式;根据提示词可知答案为extremely。

③考查定语从句。设空处引导定语从句,先行词为spot,将先行词代入定语从句后为:It could send signals to the spacecraft and to Earth in the spot.设空处作地点状语,故填where。

④考查名词。设空处作介词of的宾语,根据提示词可知设空处需填名词形式;此外“be of+抽象名词”也是固定结构,故填名词interest。

⑤考查介词。根据设空处前的more可知设空处填介词than。

⑥考查非谓语动词。设空处作目的状语,主语Chinese researchers与find为逻辑上的主动关系,故填不定式的主动形式to find。

⑦考查时态和主谓一致。根据语境及设空处后宾语从句中的谓语动词have可知设空处需用一般现在时;主语it为第三人称单数,故填means。

⑧考查语态和主谓一致。主语the moon与construct为被动关系,故设空处需用被动语态,主语为the moon,谓语动词应用第三人称单数形式,故填is constructed。

⑨考查限定词。设空处后的名词ice作“冰”讲时为不可数名词,根据上下文可知设空处填much。
