本题需结合语境和语法规则，将方框内单词转换为正确形式填空。解题时先分析每个句子的成分、所需词性，再匹配对应单词并变形：1题需名词，2题是被动语态需过去分词，3题用反身代词，4题需名词，5题用固定短语。
【解析】
1. “such a great”后接名词，invent的名词形式是invention，意为“发明”，符合“智能家庭机器人是伟大发明”的语境，故填invention。
2. 句子为被动语态，结构是“be+过去分词”，and连接并列的过去分词，test的过去分词是tested，故填tested。
3. “by oneself”是固定搭配，意为“独自”，it的反身代词是itself，符合“机器人独自做家务”的语境，故填itself。
4. 根据“take clear photos”可知需要相机，camera意为“相机”，符合句意，故填camera。
5. “hundreds of”是固定短语，意为“成百上千的”，句首单词首字母大写，故填Hundreds of。
