【分析】
本题为选词填空结合非谓语动词（不定式to do、动名词doing）的用法题，解题思路：1. 先明确方框内单词词义：earn（赚）、post（发布）、improve（改进）、invent（发明）、fix（解决；修理）；2. 回忆常见动词的非谓语固定搭配：love doing sth（表爱好）、decide to do sth（表决定）、keep doing sth（表持续做）、want to do sth（表想要）；3. 结合语境匹配单词与非谓语形式，完成填空。
【解析】
1. 第1空：love的固定搭配为love doing sth（表长期爱好），结合语境“喜欢一个接一个解决问题”，方框中fix意为“解决”，故填fixing。
2. 第2空：decide的固定搭配为decide to do sth（表决定），结合语境“决定发明新的手臂”，方框中invent意为“发明”，故填to invent。
3. 第3空：keep的固定搭配为keep doing sth（表持续做），结合语境“一直改进工作”，方框中improve意为“改进”，故填improving。
4. 第4空：want的固定搭配为want to do sth（表想要），结合语境“不想从中赚钱”，方框中earn意为“赚（钱）”，故填to earn。
5. 第5空：decide的固定搭配为decide to do sth，结合语境“决定免费在网上发布设计”，方框中post意为“发布”，故填to post。
