Question

【題目】 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).

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 5GB.5G can be compared with 4G

C.the “5G epoch” can come soonerD.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.

Answer 1

【答案】

【1】B

【2】C

【3】A

【4】D

【5】D

【解析】

本文主要講了人們對5G的了解甚少，只知道它的速度快。事實(shí)上除了速度外，5G還有更多的優(yōu)勢。它至少可以用于兩個目的——連接所有的東西和消除延遲。

【1】詞句猜測題。根據(jù)上文They have also announced that 5G technology would be widely used by 2020, causing some experts to say the “5G epoch” is coming. 他們還宣布，到2020年，5G技術(shù)將得到廣泛應(yīng)用，導(dǎo)致一些專家認(rèn)為…即將到來。由2020年廣泛使用5G，可知5G的時代來了，故選B。

【2】細(xì)節(jié)理解題。根據(jù)上文In this way, these cars can avoid obstacles(障礙) and move on driving routes, which will help improve self-driving technology. 通過這種方式，這些汽車可以避免障礙，并在駕駛路線上行駛，這將有助于提高自動駕駛技術(shù)。故選C。

【3】細(xì)節(jié)理解題。根據(jù)上文Factories can produce more macro base stations to allow more people to use. The more users, the lower cost. 工廠可以生產(chǎn)更多的宏基站，讓更多的人使用，用戶越多，成本越低。故選A。

【4】推理判斷題。A. people know a lot about 5G.根據(jù)上文“when reporting … only described it as a “much faster” technology than 4G, …5G is that they could “download a movie within one second”.可知人們對5G的了解甚少，只知道它的速度快。所以此項(xiàng)說法錯誤，排除A；B. 5G is much faster but more expensive than 4G.根據(jù)上文 5G technology won’t cost as much as they thought. 5G技術(shù)的成本不會像他們想象的那么高。所以此項(xiàng)說法錯誤，排除B；C. connecting everything is the strongest function of 5G. 根據(jù)上文Connecting everything is one of the strongest functions of 5G. 連接一切是5G最強(qiáng)的功能之一。所以此項(xiàng)說法錯誤，排除C；D. online game players can enjoy continuous high speed of 5G. 根據(jù)上文This problem can be solved with 5G technology, because it will make sure of continuous high speed. 這個問題可以用5G技術(shù)解決，因?yàn)樗鼘⒋_保連續(xù)高速�？芍�此說法正確，故選D。

【5】主旨大意題。根據(jù)上文Actually, 5G technology has many more advantages than 4G besides the speed. 事實(shí)上，5G技術(shù)除了速度外，還有更多的優(yōu)勢。通讀全文，可知主要講了5G除了速度快之外，還有很多優(yōu)勢，故選D。

在做細(xì)節(jié)理解題時一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確的選擇；在做推理判斷題時不要以個人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷。
