2. What are; doing
3. isn't listening
4. She; does her
5. is listening
6. is asking
7. is; doing; making
8. washing; helping him

1. 对谓语动作提问用疑问词What，主语Mother是第三人称单数，一般现在时特殊疑问句需借助助动词does，谓语动词还原为原形do。
2. 现在进行时对动作提问用What，主语you对应的be动词是are，句子结构为“What+be+主语+doing”。
3. 现在进行时变否定句，直接在be动词is后加not（缩写为isn't），现在分词保持不变。
4. 主语换为she（第三人称单数），一般现在时谓语动词do变does，物主代词their换为her。
5. now是现在进行时标志，现在进行时结构为“be+doing”，主语My sister是第三人称单数，be动词用is，listen的现在分词是listening。
6. 中文表达为现在进行时，结构为“be+doing”，主语My brother是第三人称单数，be动词用is，ask的现在分词是asking。
7. 第一句是现在进行时特殊疑问句，主语that girl是第三人称单数，be动词用is，谓语用doing；“整理床铺”的现在进行时表达为making the bed。
8. 现在进行时结构为“be+doing”，wash的现在分词是washing；“帮助他”用helping him，him是he的宾格形式。
