解析
【分析】
做完形填空需先通读全文把握主旨，再结合上下文语境、词义辨析、固定搭配等逐一分析每个空：先理解文章讲的是安徽少年丁晨发明爬楼梯助力器获奖的故事，再根据每句的逻辑关系、词汇含义选择合适选项，比如第1题对应前文的“invented a tool”，第2题是因果关系，第3题呼应爬楼梯的主题，以此类推。
【解析】
1. 考查名词辨析：study（学习）、plan（计划）、job（工作）、invention（发明）。前文提到丁晨发明了工具，因此他获奖是因为这项发明，选D。
2. 考查连词辨析：but（但是）、though（虽然）、so（所以）、because（因为）。家住老楼和每天爬楼梯是因果关系，前因后果用so，选C。
3. 考查名词辨析：stairs（楼梯）、walls（墙）、hills（山）、chairs（椅子）。结合上下文，爷爷爬楼梯困难，选A。
4. 考查形容词比较级：better（更好）、harder（更难）、luckier（更幸运）、heavier（更重）。生病后爬楼梯的难度增加，选B。
5. 考查副词辨析：slowly（慢地）、quickly（快地）、easily（容易地）、badly（糟糕地）。丁晨发明的目的是让爷爷奶奶更容易上楼，选C。
6. 考查动词辨析：found（发现）、thought（想）、lost（丢失）、solved（解决）。三年后丁晨解决了爬楼梯的问题，选D。
7. 考查动词辨析：jump（跳）、run（跑）、pull（拉）、walk（走）。助力器的功能是拉人向上，选C。
8. 考查固定搭配：make sth real（使某物成为现实），老师帮助丁晨让他的想法成真，选A。
9. 考查动词短语：got on（上车）、worked together（一起工作）、came out（出版）、worked out（算出）。丁晨和老师一起花了半年设计助力器，选B。
10. 考查动词辨析：buy（买）、need（需要）、search（搜索）、produce（生产）。未来想找公司生产这项发明，选D。
