Big telecommunications companies such as Huawei, Samsung and Qualcomm have announced their latest fifth generation (5G) products. They have also announced that 5G technology would be widely used by 2020, causing some experts to say the “5G epoch” is coming. Yet, when reporting about 5G, many reporters only described it as a “much faster” technology than 4G. As a result, what people know about 5G is that they could “download a movie within one second”.

Actually, 5G technology has many more advantages than 4G besides the speed. It can be used for at least two purposes－for connecting everything and removing delays(消除網(wǎng)絡(luò)延時(shí)).

Connecting everything is one of the strongest functions of 5G. It makes the Internet Things possible. Take driverless smart cars as an example. 5G technology can connect all parts of a transportation system including traffic lights, CCTV cameras and cars to build up perfect coordination(協(xié)調(diào)). In this way, these cars can avoid obstacles(障礙) and move on driving routes, which will help improve self-driving technology.

And removing delays might be useful especially in online games. Even long after 4G technology was introduced, players still worried about losing games because of low speed. This problem can be solved with 5G technology, because it will make sure of continuous high speed.

And for those people who think that 5G costs will be very high, they need not worry. Compared with 4G macro base station, a 5G macro base station can provide service to more users. Factories can produce more macro base stations to allow more people to use. The more users, the lower cost. Therefore, 5G technology won’t cost as much as they thought.

1.The underlined word “epoch” in Para 2 means ________.

A.技術(shù) B.時(shí)代 C.設(shè)備 D.訊號

2.5G technology can help improve self-driving technology because ________.

A.it makes the self-driving car run much faster

B.it helps to connect the cars with the Internet

C.it helps the cars avoid obstacles and move on driving routes

D.it helps the cars control the traffic lights and CCTV cameras

3.Factories can produce more macro base stations so that ________.

A.people can pay less for 5G B.5G can be compared with 4G

C.the “5G epoch” can come sooner D.few people can enjoy the 5G technology

4.According to the passage, we can know that ________.

A.people know a lot about 5G

B.5G is much faster but more expensive than 4G

C.connecting everything is the strongest function of 5G

D.online game players can enjoy continuous high speed of 5G

5.What’s the main idea of the passage?

A.The “5G Epoch” is coming. B.The latest 5G products have been invented.

C.5G technology costs less with higher speed. D.5G technology is more than about high speed.

閱讀下文并回答問題。

People are playing video games everywhere they go these days, whether they’re riding a bus, waiting for the subway or sitting in a restaurant Some of them enjoy these games so much that they can't put them down.

But is playing video games a healthy habit? The World Health Organization (WHO)doesn't think so.In June, it accepted" gaming disorder”(游戲上癮) as a mental(精神的) health problem in its International Classification of diseases(國際疾病分類), CNN reported.

According to the International Classification of Diseases, “Gaming disorder”means continuous or longtime video-gaming behaviors.whether online or offline Of course,not everyone who plays video games has this disorder.It does have its main characteristics(特征).

Jack Melville, one of the “gaming disorder”video game players, told China Daily that when he began playing video games, he promised himself to control the playing time less than one hour.But as he played video games more and more and got more pleasure from playing games, he couldn't control the time anymore and he even played video games through the night.

Another middle school student, Camila Liran, had much trouble in her life because of “gaming disorder”.She used to have quite a few friends and like to join different school clubs However, playing video games caused serious problems to her normal life.She even argued and fought with her parents a lot because of playing too much video games.

In fact, some countries are working to solve this problem.South Korean has made a law to stop children under 16 from playing online games between midnight and 6 am, USA.Today reported.Chinese tech company Tencent is also setting limits on the time that teenagers can play its games.Children between 12 and 18 years old can only play two hours per day.

1.Did WHO accept “gaming disorder”as a mental health problem?

_____________________________________________________________________________

2.What is “gaming disorder”according to the International Classification of Diseases?

____________________________________________________________________________

3.According to the passage, what are the main characteristics of “gaming disorder”?(less than 25 words)
