【分析】
解题时需先理解每个句子的句意，再结合首字母提示和本课时所学单词，分析空缺处的词性、词义，进而匹配正确单词。例如第1题，根据“科技展”和“many”确定需填可数名词复数，结合首字母i对应“发明”的复数形式；第2题根据“by”和主语robot确定用反身代词；第3题结合“3D”和制作模型的功能确定为打印机；第4题根据“制作现代轻便物品”和句首首字母确定为塑料；第5题根据被动语态结构和首字母确定为过去分词形式的“生产”。
【解析】
1. 句意：汤姆在科技展上看到很多很棒的发明。many后接可数名词复数，首字母为i，故填inventions。
2. 句意：机器人能独自完成困难的任务。by oneself表示“独自”，主语是the robot，对应反身代词itself，故填itself。
3. 句意：3D打印机能在十分钟内制作飞机模型。结合“3D”和制作模型的功能，首字母为p，故填printer。
4. 句意：塑料帮助制作很多现代又轻便的东西。此处作主语需用名词，句首首字母大写，首字母为P，故填Plastic。
5. 句意：这些智能眼镜被生产来帮助人们工作时拍照和查消息。此处为被动语态（are+过去分词），首字母为p，故填produced。
【答案】
1. inventions
2. itself
3. printer
4. Plastic
5. produced
【知识点】

【点评】
本题考查根据句意和首字母补全单词，聚焦本课时核心单词的掌握，需结合语境分析词性与词义，是基础型词汇题，难度适中。
