分析 【高分句型一】
It is important for us to save our earth对于我们来说拯救我们地球是重要的．
it is+adj+for sb+to do sth对某人来说做某事是怎么样的，it是形式主语，动词不定式做真正主语．
【高分句型二】
①In order to save power，we should turn off the lights ②when we leave a room为了节约能源，我们离开房间的时候应该关灯．
①in order to do sth 为了做某事．做目的状语．
②when引导的时间状语从句．

解答 Save Our Earth
