【分析】
本文是一篇说明文。文章主要阐释了现在可以购买5G手机的理由。
81．
考查时态和语态。句意：自从去年10月中国实现5G商业化以来，朋友们一直问我这个问题。设空处为主句谓语动词，throw与this question为动宾关系，用被动语态，根据ever since可知，主句用现在完成时。故填has been thrown。
82．
考查代词。句意：首先，中国现在有广泛的5G覆盖，这使得消费者使用5G智能手机很方便。句中用it形式宾语，真正的宾语为不定式to use 5G smartphones，make it adj. for sb. to do sth.“使得做某事对于某人来说......”。故填it。
83．
考查名词的数。句意：目前，中国所有地级市都有5G信号，超过300个城市的消费者在地铁、公园散步、商场购物时都能接入5G信号。consumer为可数名词，上文没有冠词，应用复数形式。故填consumers。
84．
考查时态。句意：目前，中国所有地级市都有5G信号，超过300个城市的消费者在地铁、公园散步、商场购物时都能接入5G信号。根据句中的谓语动词are和并列动词shopping可知，用应用现在分词和are构成现在进行时。故填taking。
85．
考查介词。句意：此外，电信运营商已经宣布了明年5G信号覆盖重镇的计划，这将吸引更多的人使用5G智能手机。cover A with B“用B事物覆盖A事物”，为固定搭配。故填with。
86．
考查副词。句意：与此同时，5G数据包的价格也大幅下降，从今年年初的每月120多元（18.3美元）降至现在的约90元，让更多的人能够负担得起享受5G服务的技术。修饰动词drop，用副词形式。故填significantly。
87．
考查形容词。句意：与此同时，5G数据包的价格也大幅下降，从今年年初的每月120多元（18.3美元）降至现在的约90元，让更多的人能够负担得起享受5G服务的技术。分析可知，此处应用形容词作tech的补足语，结合句意，“可负担的、负担得起的”表达为affordable。故填affordable。
88．
考查连词。句意：现在有更多的5G智能手机可供选择，其中一些可能还是太贵了，而最便宜的现在只要999元。根据语境以及上下文可知，此处表示转折，应用连词but或者while。故填but/while。
89．
考查定语从句。句意：中国三大电信运营商也在开发一种新型的5G短信服务，旨在用一种更丰富、提供电话簿查询并能传输呼叫后多媒体的系统取代现有的短信服务。先行词为system，指物，在定语从句中作主语，所以用关系代词which或者that引导。故填that/which。
90．
考查虚拟语气。句意：所以，是的，是时候买一部5G智能手机了。It is (high) time that 后的从句谓语动词用过去式或用should加动词原形的虚拟语气。故填bought/ should buy。
