30、、普通的标准，E项中的“a common WiFi standard”与设空后的“new WiFi standard”对应，再结合常识和语境可知答案选E项。3A根据前一句可知，根据WiFi联盟的说法，WiFi是一个商标术语，用来描述基于IEEE无线通信标准802.11的设备或技术，下文表明WiFi联盟聘请了营销公司Interbrand为它起了一个短一点的名字：WiFi；由此可知，上文的那个名字又长又拗口。故A项符合语境。mouthful意为“又长又拗口的词(或短语)”。4D根据下文中的“The rumor that”和“Some members didnt understand”可推知，人们对
31、于WiFi是什么这个问题还有一些争议，故选D。5G根据设空后一句可知，作者建议不要混淆两者；设空前两句又表述该联盟的标签带来了混淆。由此可知，G项“而且，虽然该联盟去除了这个标签，但它带来的困惑到现在仍然存在”符合语境。.语法填空(2019石家庄市重点高中高三毕业班摸底考试)I can well remember that I was once asked to deliver a speech titled “A Real Test in My Life” before the whole class at the age of 9!

36、ay考查动词的时态。根据上文中的was可知，文中描述的事情发生在过去，故此处用一般过去时，故填lay。5was forbidden考查动词的时态和语态。forbid和句子的形式主语it之间是动宾关系，且事情发生在过去，故用一般过去时的被动语态。6trembling考查非谓语动词。“with宾语(名词或代词)宾补”为独立主格结构。此处my legs和tremble构成逻辑上的主谓关系，故用现在分词形式。7myself考查代词。根据语境可知，此处表示“我找到了状态”，应为“found myself back”，故应填反身代词myself。8what考查宾语从句的连接词。分析句子结构可知，空格处引导
37、宾语从句，在从句中作主语，表示“的东西”，故用what引导该宾语从句。9confidence考查词性转换。由空格前的形容词性物主代词my可知，此处用名词形式，即confidence。10greatest考查形容词的最高级。根据语境和空格前的定冠词the以及空格后的名词difficulty可知，此处应用形容词的最高级形式，故填greatest。.书面表达社会发展到了2080年，照顾老年人成了一个突出的社会问题。你公司顺应社会需求适时推出了家用机器人。该机器人的主要功能有：1可以在固定的时间做饭，做饭时间可以根据个人需要进行调整；2可以陪老人聊天、下棋、做运动等；3及时处理突发事件，例如在老人突然
