答案以及解析
一、填空题
1.答案：impressions
解析：句意为:第一印象往往会持续很长一段时间,因此要尽量保持精力充沛、穿着得体。分析句子结构可知,设空处在句中作主语,应填impress的名词形式,再由谓语动词 last 可知,主语为复数。
2.答案：whom
解析：“ most of+关系词”引导非限制性定语从句,先行词为young people,指人,关系词作阶词of的宾语,故用whom。
3.答案：who
解析：句意为:她创建了一个慈善机构来纪念因阿尔茨海默病去世的祖母。设空处引导非限制性定语从句,先行词为her grandmother,指人,关系代词在定语从句中作主语,故应用关系代词who引导该从句。
4.答案：interaction
解析：句意为:玩游戏和唱歌提供了课堂互动的机会。设空处之前是名词classroom,此处为名词修饰名词,作介词for 的宾语,意为“交流;沟通”,故填interaction。
5.答案：Having been tested
解析：句意为:经过几次试验之后,这一新产品将上市。句中已经有谓语will be put,设空处与其之间没有连词连接,故用非谓语形式。test与句子主语 the new product 之间是逻辑上的被动关系,并且先于be put into the market这一动作发生,故填现在分词完成式的被动式。
6.答案：with/by
解析：句意为:我们和她在一起感觉很自在,她渊博的知识给我们留下了深刻的印象。be impressed with/by ...是固定搭配,意为“对……印象深刻”。故填 with/by。
7.答案：praising
解析：句意为:总之,他们的工作成果如此令人印象深刻,所以他们都值得表扬和学习。设空处与learning from 并列作 deserve 的宾语,应用动名词形式;deserve doing 意为“某事值得被做”,用主动形式表示被动意义。故填 praising。
8.答案：where
解析：句意为:他们开始探索丛林,在那里他们将认识到神秘自然世界的价值。设空处引导非限制性定语从句,先行词为the jungle,关系词在从句中作地点状语,应用关系副词where 引导该从句。故填 where。
9.答案：As
解析：句意为:据报道,在过去的几个月里,这个城市的空气质量有了很大的改善。设空处引导非限制性定语从句,从句缺少主语,关系词指代整个主句的内容,表示“正如”,因此,应用As引导该从句。
10.答案：in
解析：句意为:“我从没想过我能见到这样的地方。”他最后低声说道。in a whisper 为固定短语,意为“低声说;耳语”。
二、七选五
答案：DFBGE
解析：①下文To help all of us understand them, we have listed some facts everyone should know. (为了帮助我们所有人明白它们，我们必须列出一些人人都应该知道的事实)与D. Why does 5G matter so much in people's daily life (为什么5G在人们的生活中如此重要呢？)承接自然，下文的them就指代上文提到的两个问题，故选D项。
②下文With 5G there is a possibility that we can do everything.(有了5G我们就有可能做任何事情了)与F. 5G means faster data speeds and ultra-low latency (超低延迟).(5G意味着更快的数据和超低延迟)承接自然， 因为数据更快、延迟超低，所以让人们做任何事情变得有可能。故选F项。
③根据下文的Self-driving cars, which will depend on ultra-fast data transmission speeds to communicate with other cars as well as their surroundings, promise a safer transportation system if and when technology is fully realized.(自动驾驶汽车将依靠超高速的数据传输速度与其他车辆及周围环境进行通信。如果技术完全实现，自动驾驶车辆将带来一个更安全的交通)可知，本段主要讲述5G可以帮助自动驾驶车辆成为现实，B. 5G will help make self-driving cars a reality.(5G会帮助自动驾驶车辆成为一个现实)可以作为本段小标题，self-driving cars是关键词，故选B项。
④上文Video meeting, e-learning and other Internet-enabled work applications will be possible to the point where people can use them as easily in their home or on the road as in the office or classroom. (视频会议、网上学习和其它基于互联网的工作应用将成为可能，人们可以在家里或路上像在办公室或教室里一样轻松地使用它们)与G. It will be also easier for doctors to treat patients remotely by 5G.(通过5G医生远程治疗病人也将变得更容易)承接自然，上下文构成明显的并列关系，都讲5G让工作和学习变得容易，easily和easier是关键词。故选G项。
