1. There are white clouds high in the (天空).
2. Can you (闻) something burning?
3. The kids are washing their hands in the (浴室).
4. The city (中心区) is always filled with people, especially during some festivals.
答案：1. sky；2. smell；3. bathroom；4. centre
解析：
1. 根据中文释义“天空”，结合固定表达in the sky，此处填sky；2. 中文释义“闻”对应的英文单词是smell，情态动词can后接动词原形，故填smell；3. “浴室”的英文是bathroom，in the bathroom是常用地点短语，所以填bathroom；4. “中心区”对应的英文是centre，city centre为固定搭配，因此填centre。
二、根据要求改写句子
1. My new school looks like a big garden. (对画线部分提问)
your new school ?
2. Leo lives on the second floor to keep dry. (对画线部分提问)
Leo on the second floor?
3. My house is made of bamboo. (对画线部分提问)

1. My new school looks like a big garden. (对画线部分提问)
your new school ?
2. Leo lives on the second floor to keep dry. (对画线部分提问)
Leo on the second floor?
3. My house is made of bamboo. (对画线部分提问)
your house ?
4. Where would you like to live? (改为同义句)
Where ?
答案：1. What does; look like
2. Why does; live
3. What is; made of
4. do you want to live
2. Why does; live
3. What is; made of
4. do you want to live
解析：
1. 画线部分是事物，用what提问，原句为一般现在时，主语your new school是第三人称单数，助动词用does，谓语动词look用原形，结构为“What + does + 主语 + look like?”。
2. 画线部分是表目的的原因状语，用why提问，原句为一般现在时，主语Leo是第三人称单数，助动词用does，谓语动词live用原形，结构为“Why + does + 主语 + live + 其他?”。
3. 画线部分是制作材料，用what提问，原句是“be made of”结构，变疑问句时将be动词is提前，结构为“What + is + 主语 + made of?”。
4. “would like to do sth.”的同义表达为“want to do sth.”，主语是you，一般现在时，助动词用do，故改写为对应结构的句子。
