解析
【分析】
这道题考查英语现在进行时的用法，解题时需先识别句子中的时间/语境标志（如now、It's+具体时刻、Listen!、Look!、right now等），确定句子需用现在进行时；再根据主语的单复数人称确定be动词（单数主语用is，复数主语用are，第一人称I用am），最后将括号内的动词转换为对应的现在分词形式（注意特殊变化规则：以不发音e结尾的动词去e加ing，重读闭音节动词双写尾字母加ing等）。
【解析】
1. 主语Who视为单数，时间标志now，现在进行时结构为is + sing的现在分词singing，故填is singing；
2. 主语The students是复数，时间标志It's eight o'clock，be动词用are，have的现在分词是having，故填are having；
3. 主语The baby单数，标志词Listen!，be动词is，cry的现在分词crying，故填is crying；
4. 主语The twins复数，标志词Look!，be动词are，wear的现在分词wearing，故填are wearing；
5. 主语Grandparents复数，语境暗示正在进行的动作，be动词are，sleep的现在分词sleeping，故填are sleeping；
6. 主语Tom and his sister复数，语境暗示正在等待，be动词are，wait的现在分词waiting，故填are waiting；
7. 主语He单数，答语表正在进行的动作，be动词is，play的现在分词playing，故填is playing；
8. 主语She单数，时间标志right now，be动词is，shop的现在分词shopping（双写p加ing），故填is shopping；
9. 第一空是现在进行时一般疑问句结构Is + 主语 + doing，故填cleaning；第二空主语She单数，be动词is，paint的现在分词painting，故填is painting；
10. 第一空是现在进行时特殊疑问句结构What + be + 主语 + doing，故填doing；第二空主语I，be动词am，eat的现在分词eating，故填am eating。
