【分析】这道题考查现在进行时的用法，解题思路为：首先根据句中的时间标志词（如now、look、listen、at this moment等）判断句子需用现在进行时；其次明确现在进行时的结构为“am/is/are + 动词的现在分词（doing形式）”；再根据主语的单复数确定be动词的形式（单数主语用is，复数主语用are）；疑问句需将be动词提前，回答时对应使用be动词，动词部分保持现在分词形式。
【解析】
1. 句中时间标志词为now，用现在进行时；主语your dog是单数，be动词用Is，sleep的现在分词是sleeping；答句主语it为单数，be动词用is，故填Is; sleeping; is。
2. 句中时间标志词为now，主语Tom and Anna是复数，be动词用are，wait的现在分词是waiting，故填are waiting。
3. 句中时间标志词为now，主语you对应be动词are，do的现在分词是doing；答句主语we是复数，be动词用are，play的现在分词是playing，故填are; doing; are playing。
4. 主语she是单数，疑问句be动词提前用Is，fly的现在分词是flying；答句主语she为单数，be动词用is，do的现在分词是doing，故填Is; flying; is doing。
5. 句中时间标志词为at this moment，主语His parents是复数，be动词用are，watch的现在分词是watching，故填are watching。
6. 句中时间标志词为Look，主语Three boys是复数，be动词用are，practise的现在分词是practising；后面主语Mr Chen是单数，be动词用is，kick的现在分词是kicking，故填are practising; is kicking。
7. 句中时间标志词为Listen，主语Someone是单数，be动词用is，sing的现在分词是singing，故填is singing。
8. 句中时间标志词为Look，主语Jim是单数，be动词用is，talk的现在分词是talking，故填is talking。
9. 句中时间标志词为now，主语Sherry是单数，be动词用is，lie的现在分词是lying，故填is lying。
10. 句中时间标志词为now，主语She是单数，be动词用is，cook的现在分词是cooking，故填is cooking。
【答案】1. Is; sleeping; is 2. are waiting 3. are; doing; are playing 4. Is; flying; is doing 5. are watching 6. are practising; is kicking 7. is singing 8. is talking 9. is lying 10. is cooking
