【分析】
这道题是英语句型转换专项习题，解题时首先要先判断原句的句式结构、时态、谓语类型，再对应不同转换要求的规则推导答案：
1. 改写一般疑问句时，先确认原句是否有be动词、情态动词、助动词，有就直接把这类词提到句首并大写，没有的话要借助对应时态的助动词完成变换；
2. 改写否定句时，优先找句中be/情态/助动词，直接在后面加not，实义动词作谓语的句子要借助助动词的否定形式，后续接动词原形；
3. 祈使句改否定直接在句首加Don't即可；
4. 同义句转换要抓住原句核心语义，找到对应语义的替换结构，比如if not和unless互换、so that和in order to互换等；
5. 合并句子要注意引导词的用法，调整主从句语序保证语义通顺。
【解析】
我们逐题推导答案：
1. 原句是主系表结构It is...，改一般疑问句直接将be动词is提前至句首大写，后续保留主语it，因此填Is it。
2. 原句是一般现在时，主语many people为复数，谓语是实义动词like，变否定需借助助动词don't，后接动词原形like，因此填don't like。
3. 原句是一般将来时（will+动词原形），改一般疑问句将will提前至句首大写；题目给出肯定回答后半句they will，因此开头填Yes。
4. 原句是肯定形式的祈使句，变否定句直接在句首加Don't，首字母大写即可。
5. 问句是表委婉请求的Could you...，肯定回答可用Yes/Sure，后续用对应情态动词can作答。
6. 原句含情态动词should，改一般疑问句直接将should提前至句首大写；肯定回答保持情态动词一致，填should。
7. 原句语义为“如果你不完成作业，你就不能出去玩”，对应同义表达“你不能出去玩，除非你完成作业”，if not的同义替换连词是unless，因此填unless。
8. as soon as意为“一……就……”，引导时间状语从句，将原句前半句作为从句，后半句作为主句，调整语序后得到正确句子。
9. 原句so that引导目的状语从句，对应三个空的目的状语结构in order to，后接动词原形，符合空格要求，因此填in order to。
10. 原句If it doesn't rain（如果不下雨）同义替换为Unless it rains（除非下雨），第一空填Unless，主语it是第三人称单数，谓语动词用rains。
【答案】
1. Is it
2. don't like
3. Will; Yes
4. Don't
5. Yes/Sure; can
6. Should; should
7. unless
8. As soon as he saw his mother, he ran to her.
9. in order to
10. Unless; rains
