解析

【分析】
这道题全部围绕过去进行时的句型转换考点展开,解题时首先要牢记过去进行时的核心结构为was/were + 动词现在分词,再根据不同改写要求对应规则思考:
1. 对地点画线提问就用where,对动作画线提问用what...doing,对事物画线提问用what,注意特殊疑问句要把be动词放到主语前;
2. 改一般疑问句直接把句中的was/were提前到句首大写,现在分词保留不变;
3. 改否定句直接在was/were后加not即可;
4. 两个同时发生的延续性过去动作用while连接,前后都用过去进行时结构;
5. 改写为过去进行时直接套用was/were doing的结构,匹配对应主语的be动词形式即可。
【解析】
1. 画线部分in the library是地点状语,对地点提问用特殊疑问词Where,原句主语转换为you后对应的过去式be动词是were,谓语现在分词reading保留,因此填Where were; reading。
2. 过去进行时改一般疑问句,直接将句中be动词was提到句首首字母大写,后续现在分词taking保留,因此填Was; taking。
3. 画线部分sleeping是过去进行时的动作内容,对动作提问用特殊疑问词What,搭配doing表示“做什么”,主语they对应的过去式be动词是were,因此填What were; doing。
4. 画线部分the rainstorm's influence是事物内容,对事物提问用特殊疑问词What,原句be动词is提前到主语前,因此填What is。
5. 画线部分under the desk是地点状语,对地点提问用Where,主语he对应的过去式be动词是was,因此填Where was。
6. 过去进行时改一般疑问句,将be动词was提前到句首大写,后续现在分词waiting保留,因此填Was; waiting。
7. 两个同时发生的延续性过去动作使用while连接,后半句主语my father是第三人称单数,对应过去进行时结构为was watching,因此填while; was watching。
8. 过去进行时改否定句,直接在be动词were后加not,后续现在分词playing保留,因此填were not playing。
9. 过去进行时结构为was/were + 现在分词,主语Ben是第三人称单数,be动词用was,take的现在分词为taking,因此填was taking。
10. while引导延续性动作的时间状语从句,从句主语we对应的过去式be动词是were,talk的现在分词为talking,句首首字母大写,因此填While; were talking。
【答案】
1. Where were; reading 2. Was; taking 3. What were; doing 4. What is 5. Where was 6. Was; waiting 7. while; was watching 8. were not playing 9. was taking 10. While; were talking
【知识点】
过去进行时,特殊疑问句转换,一般疑问句转换
【点评】
本题全面覆盖了过去进行时的各类常见句型变换考点,从特殊疑问词的选用、不同句式的改写规则到时态改写、连词合并句子都有涉及,只要熟练掌握过去进行时的基础结构,注意不同主语对应的be动词搭配,就能顺利完成所有改写,是巩固过去进行时知识点的典型基础题型。
