【分析】
主动语态变被动语态的核心是:将主动句的宾语变为被动句的主语,主动句的主语可保留(加by引出)或省略,谓语动词变为“be + 过去分词”,且be动词的时态需与原主动句时态一致。需结合每个句子的时态和成分,对应转换结构。
【解析】
1. 原句为一般将来时,主动谓语是will use,宾语AI tools作被动主语,被动结构为will be used,保留状语in more fields,故转换为:AI tools will be used in more fields;
2. 原句为一般现在时,主动谓语是use,宾语language learning apps作被动主语,被动结构为are used,by引出原主语more and more people,故转换为:Language learning apps are used by more and more people;
3. 原句为一般将来时,主动谓语是will build,宾语a new library作被动主语,被动结构为will be built,保留地点状语in our school,故转换为:A new library will be built in our school;
4. 原句为一般现在时,主动谓语是name,宾语Lao She作被动主语,被动结构为is named,保留引号内的称谓,故转换为:Lao She is named "the People's Artist"。
【答案】
1. AI tools will be used in more fields
2. Language learning apps are used by more and more people
3. A new library will be built in our school
4. Lao She is named "the People's Artist"
