中国华为联合英国沃达丰拨出世界上第一个5G电话

Chinese mobile giant Huawei and British telecom provider Vodafone claimed to have made the first 5G data phone call in the world this week, the latest development in the race to faster mobile data connections.
The call, made on Tuesday between a computer in Barcelona and a mobile phone in Madrid, used a dual “4G to 5G connection” which can reach speeds up to eight times faster than the current 4G standard. Vodafone added that following Tuesday’s first voice call, it successfully completed a video call using 5G data connection on Huawei’s Radio Access Network (RAN) equipment.
Vodafone officials told Spanish newspaper that previous tests did not meet up-to-date standards, but rather used experimental settings that wouldn’t be compatible(兼容的) with most current 4G technologies.
Yang Chaobin told Newsweek that his firm would be starting commercial testing with Vodafone in the near future.
As the world’s second largest smartphone maker, Huawei has already announced plans to invest 5 billion yuan (786 million US dollars) in developing 5G this year. The company’s first 5G computer chips and mobile phones are set for release in 2019.
5G stands for “fifth generation” and refers to the newest standard for mobile wireless networks. Telecoms companies expect 5G to be used widely in 2020, bringing faster Internet speeds capable of supporting “the Internet of things” including web-connected household appliances, lights and driverless cars, as well as virtual reality and augmented reality technologies.

1.What kind of call is the first 5G call made by Huawei and Vodafone?

A Text call.

B Voice call.

C Video call.

D All of the above.

解析：选B。细节理解题。根据第二段第二句Vodafone added that following Tuesday’s first voice call, it successfully completed a video call using 5G data connection on Huawei’s Radio Access Network (RAN) equipment.可知这个世界上第一个5G电话是一个语音电话，故选B。

2.Who could Yang Chaobin be?

A A staff of Huawei.

B A staff of Vodafone.

C A reporter from Newsweek.

D The writer of this passage.

解析：选A。推理判断题。根据全文可知本文主要讲述了华为与英国电信运营商沃达丰联合测试5G技术相关情况，华为是设备技术提供商，结合后文提到的“他的公司”将联合沃达丰和测试设备可知这里的他的公司是指华为，因此杨超斌是华为员工，故选A。

3.Which of the following words can replace the underlined word “invest”?

A Pay.

B Cost.

C Take.

D Spend.

解析：选D。词义猜测题。invest在这里是投资的意思，其主语是人、宾语是钱，只有spend有此用法，故选D。

4.What can we learn from the passage?

A All things will be connected with the Internet in 5G time.

B Huawei will devote a lot to make the standard of 5G.

C Huawei planned to release its first smartphone in 2019.

D 5G equipment is much faster than the current 4G technology.

解析：选D。推理判断题。根据第二段第一句The call, made on Tuesday between a computer in Barcelona and a mobile phone in Madrid, used a dual “4G to 5G connection”which can reach speeds up to eight times faster than the current 4G standard.和第三段Vodafone officials told Spanish newspaper that previous tests did not meet up-to-date standards, but rather used experimental settings that wouldn’t be compatible with most current 4G technologies.可知测试时的5G设备的运行速度是目前绝大多数4G技术的8倍，而测试用的是实验设备而非正式设备，正式设备会更快可知5G技术应该比4G技术快很多，故选D。

5.Which column of a website can you see this passage?

A Education and culture.

B Science and technology.

C Pop and entertainment.
