Zhan Haojing gave puppet shows at school. 合并：Because Zhan Haojing gave puppet shows at school, more young people got to know this art. (或者：More young people got to know this art because Zhan Haojing gave puppet shows at school.) 逻辑辨析：在使用时要注意逻辑关系。如果是“如果……就会……”，用 if；如果是解释原因，用 because。例如：If you are tired, take a rest. (如果你累了，就休息一下。) / I'm late because the bus was late. (我迟到了，因为公交车晚点了。) ◇Part 03 拓展深化 提｜升｜练｜习 一、单项选择 1. As the most ______ group, young people always create new things around us.

Zhan Haojing gave puppet shows at school. 合并：Because Zhan Haojing gave puppet shows at school, more young people got to know this art. (或者：More young people got to know this art because Zhan Haojing gave puppet shows at school.) 逻辑辨析：在使用时要注意逻辑关系。如果是“如果……就会……”，用 if；如果是解释原因，用 because。例如：If you are tired, take a rest. (如果你累了，就休息一下。) / I'm late because the bus was late. (我迟到了，因为公交车晚点了。) ◇Part 03 拓展深化 提｜升｜练｜习 一、单项选择 1. As the most ______ group, young people always create new things around us.
