【分析】
本题考查一般将来时的相关句式运用，需根据不同题型要求转换结构：
1. 第21题：对划线部分（动作）提问，用疑问词what，结合一般将来时结构，将助动词will提前，划线动作用do代替；
2. 第22题：一般将来时句子变一般疑问句，直接将助动词will提前，肯定回答遵循“Yes+主语+will”结构；
3. 第23题：there be句型的一般将来时（there will be）变一般疑问句，提前will，否定回答遵循“No+there+won't”结构；
4. 第24、25题：用将来时间状语改写句子，需将一般现在时改为一般将来时，结构用“will+动词原形”或“be going to+动词原形”。
