Ⅰ. 【语篇解读】本文是一篇说明文。文章介绍了半导体在当今社会不可或缺的地位和半导体的发展趋势以及半导体的现状——芯片荒。

1. more connected　考查形容词比较级。even的意思是“更加”，修饰形容词的比较级。
2. gathering　考查动词-ing形式。本空与上文的our work，school构成并列关系，均是作介词for的宾语，故用动词-ing形式。
3. practically　考查副词。本空修饰形容词unimaginable作状语，故用副词形式。
4. are powered　考查谓语动词。句意：在多数情况下，这些重要的设备由半导体——导电的小芯片驱动。主语devices与power构成被动关系，故用被动语态。
5. our　考查代词。本空修饰名词devices作定语，故用形容词性物主代词。
6. As　考查连词。句意：随着时间的推移，半导体也被装配到汽车和房子里。本空易误填介词With。as time goes on = with time going on。
7. a　考查冠词。句意：伴随着新技术的增长和创新，生产半导体的公司继续以稳定的速度发展。本句中的rate是泛指，故用不定冠词。
8. which　考查定语从句。空格处引导非限制性定语从句且在从句中作主语，代指主句所述内容，故用which。
9. combination　考查词性转化。本空是句子的主语，且被指示代词修饰，故用名词形式。
10. prices　考查名词复数。根据下文的for many electronic products可知，此处描述多种产品的价格，故用复数形式。

Ⅱ. 【语篇解读】本文是一篇说明文。文章介绍了科技在很多方面改变了我们的生活，我们甚至无法想象没有科技的生活。过去看起来不可能的事情现在几分钟就可以完成。

1. E　关联逻辑法解题。根据空格前一句“It has transformed our lives in many ways.”及空格后一句“The things that seemed impossible in the past can now be done in just minutes.”可知，此处承接上下文，讲的是科技和生活之间的关系。E项“We cannot even think of our lives without technology.（我们甚至无法想象没有科技的生活）”承上启下。
2. A　关联逻辑法解题。根据空格前一句“Nowadays farmers use mobile apps to calculate the grass in their field.”可知，现在农民把科技运用到农业中，此处承接上文，讲的是将科技运用到农业中可以带来的好处。A项“That saves their time and money too.（这也节省了他们的时间和金钱）”正是具体的好处。
3. F　设题位置法解题。根据本段小标题“Technology and Our Lifestyle”可知，本段主要介绍科技与我们的生活方式之间的联系。F项“Technology is thought to have changed our lifestyle totally.”提及了科技与生活方式之间的关系，符合本段话题。
4. G　词汇锁定法解题。根据本段小标题“Technology and Communication”可知，本段主要介绍科技和通信之间的关系。再结合空格前一句“Nowadays we have social media, mobile phones, laptops, and the Internet with many videos that have made our communication far easier than before.”讲述现在的通信可知，空格处应该讲述过去的通信。G项“In the past, we could only imagine a video call which was not possible at that time.”讲述了过去的通信，其中的In the past与上文的Nowadays形成对照，故选G。
5. C　关联逻辑法解题。根据空格前一句“In the past, it was not easy to get information or knowledge as quickly as we do today with the help of the Internet.”可知，在过去科技不发达的情况下，想要快速获得知识很不容易。由空格后一句“Now there are online schools，online education systems where you can get educated.”可知，在科技的帮助下，现在从网络上获取知识已经很容易了。由此可知，空格处应该讲述科技给教育带来的好处。C项“Technology has expanded access to education.”讲到了科技给教育带来的好处，符合语境。

Ⅲ. 【语篇解读】本文是一篇记叙文。文章讲述了独自居住在Mackay的年迈父亲得到两位陌生“年轻人”两次友好帮助的事情。第一次是“年轻人”帮助父亲搬运货物，第二次是父亲在银行排队时，“年轻人”让父亲到旁边坐下休息，自己帮他占位置。

1. A　根据前面信息可知，父亲92岁了，虽然他性格活跃，但行动迟缓（slow）。
2. B　有一天，恶劣天气过后，我们给他打电话报平安（check in）。watch out小心；留神；注意；check in（打电话）报平安，告知行踪；set off 出发，动身；show up出现；露面。
3. D　他告诉（tell）我们他是如何买到货物。contact联系，联络；交往。
4. C　他告诉我们他是如何买到货物并把它们放到（take）车上的。pack（把……）打包；（把……）装箱。
5. B　我会帮（help）你把你的货物放进车里。allow 允许；request 要求；advise 建议。
6. D　然后他小心翼翼地把货物从手推车上卸下来，并确保它们是安全的（safe）。与前面的“小心翼翼地（carefully）”相呼应，故用safe。
7. A　父亲表示感谢时，他却说“没什么，不客气（no problem）”。no problem（回答别人的道谢或道歉）没什么，不客气，没关系；no way不可能；决不；不行；no secret不算什么秘密；no doubt毫无疑问。
8. B　我们等待时，我会帮你占住（hold）位置的。hold使保持（在某位置）。
9. C　我是在发抖还是看起来很虚弱（weak）？
10. A　我知道我父亲会觉得站立这么久很难（hard）。
11. D　父亲满怀感激地（thankfully）走过去坐下。bravely勇敢地；curiously 好奇地；properly正确地。
12. A　轮到父亲的时候，他点点头（nod），微笑着表示感谢。
13. C　我对这两位“年轻人”所表现出的善意感到惊喜（surprised）。frightened惊吓的；受惊的；害怕的；annoyed 恼怒的；生气的；attracted 被吸引的。
14. B　对那两位不能确定年龄（age）的“年轻人”……
15. B　我们感谢他们以微小（small）而有意义的方式帮助了父亲。
