【答案】BCBD

【解析】本文圍繞“什么是5G：何時開始使用：能做什么；安全風險是什么”等四方面介紹5G技術。

1.主旨大意題。根據第一段“Therehasbeenalotofnewsrecentlyabout5G,butwhatisthistechnologyandhow

mightitchangeourlives”5G這項技術是什么？它將如何改變我們的生活；可知，這篇文章的寫作目的是介紹

新的5G技術；故選B。

2.推理判斷題。根據第五段“...Suchdifficultiescouldinfluencepublicsafetyaswellasworldeconomic”數據可

能被竊取和濫用、系統的任何故障都將產生更嚴重的后果，這些困難可能影響公共安全和世界經濟；可知，

本段講述5G技術面臨的安全問題；故選C。

3.推理判斷題。根據第三段“4Gphoneswillworkon5Gnetworks,butnotat5Gspeeds”可知，4G手機將在5G

網絡上運行，選項B表述錯誤；故選B。

4.推理判斷題。根據第四段"5Gisalsoexpectedtoconnectself-drivingcarsandsupportnewtechnologies”5G還

將連接自動駕駛汽車并支持新技術；可知，5G技術可以改善人們的自駕體驗；故選Da
