解析

【分析】
本题要求根据汉语注释写出单词的正确形式,需结合句子语境、语法规则(如名词单复数、动词时态、固定搭配等)确定单词的正确形式。具体思路:先理解每个句子的含义,再根据括号内的汉语提示,结合语法要求(如one of后接名词复数、情态动词后接动词原形、第三人称单数主语的动词形式等)选择合适的单词并调整形式。
【解析】
1. 括号内“打印机”对应名词printer,此处作介词with的宾语,用单数形式,故填printer。
2. “one of + 形容词最高级 + 可数名词复数”是固定结构,“发明”对应名词invention,复数形式为inventions,故填inventions。
3. “人工智能”的固定英文表达是Artificial Intelligence,“人工”对应形容词Artificial,首字母需大写,故填Artificial。
4. “艺术展览会”对应固定短语art fair,“展览会”填fair,故填fair。
5. 主语it是第三人称单数,时态为一般现在时,“价格为(花费)”对应动词cost,第三人称单数形式为costs,故填costs。
6. 主语a baby elephant是第三人称单数,时态为一般现在时,“重量是……”对应动词weigh,第三人称单数形式为weighs,故填weighs。
7. 情态动词can后接动词原形,“解决”对应动词fix或solve,故填fix/solve。
8. “in terrible condition”是固定短语,意为“状况糟糕”,“状况”对应名词condition,故填condition。
