C 【导语】本文是一篇记叙文，讲述了墨西哥少年Daniel利用回收材料制作机器人Larry参加科学博览会，并获得赞扬的故事，体现了他的创造力。 【解析】1. 句意：来自墨西哥的Daniel Grapain最近用回收材料制作了一个机器人。 本句为现在完成时，recently常与现在完成时搭配，表示动作发生在近期，其余选项代入语义不通。 2. 句意：他回收材料，用它们做了一个名叫Larry的机器人。 上文“made a robot”及下文“the robot”，说明他制作的就是机器人，robot“机器人”符合语境。 3. 句意：怀着信心，这名学生通过拼接不同线路成功建成了Larry。 下文机器人能动且获奖，说明制作成功，且“Feeling confident”暗示结果良好，successfully符合语境，其余选项无对应语境支撑。 4. 句意：一根电缆连接不同身体部件，还包括一个让Larry能够移动的小平台。 allow sb. to do sth.为固定搭配，意为“允许某人做某事”，此处表示平台实现了机器人的移动功能，符合语境。 5. 句意：Grapain没有买任何新东西来建造拉里，甚至就连让机器人焕发生机的电源都不是新买的。 come to life是固定短语，意为“焕发生机”，符合语境。 6. 句意：“一切都是回收利用的，甚至连他戴的帽子也不例外，”这名学生在接受Maestro Marciano老师采访时分享道。这位老师在社交媒体上分享了Grapain的经历。 句中“Everything...the cap he wears”，此处递进强调“全回收”的特点，就连小零件帽子都是回收的，even符合逻辑。 7. 句意：“一切都是回收利用的，甚至连他戴的帽子也不例外，”这名学生在接受Maestro Marciano老师采访时分享道。这位老师在社交媒体上分享了Grapain的经历。 句中“shared Grapain’s...on social media”，老师分享Grapain制作机器人的相关经历，experiences“经历”符合逻辑，其余选项语义不符。 8. 句意：视频里，Grapain用遥控器让Larry移动它的胳膊和头。 句中“a remote control (遥控器) to make Larry...its arms and head”，遥控器控制机器人活动，让胳膊和头移动，move符合机器人展示的语境。 9. 句意：“你好，我是Larry，”机器人介绍自己。 机器人开口说名字，属于自我介绍，introduce oneself是固定搭配。 10. 句意：在Larry精彩的展示后，Grapain因为有创造力收获了祝贺。 Grapain用回收材料制作出功能完整的机器人，参加科展，突出他的创造力，creative符合语境。 $
