【分析】
本题为词汇运用题，需结合句子语境、词性要求及固定搭配，从给定词汇中选择并转换为正确形式填空。解题思路如下：
1. 第1空：句中游客去公园的目的是欣赏美景，需用动词不定式表目的，故选admire并转换为to admire；
2. 第2空：修饰动词grown需用副词，给定词rapid为形容词，转换为副词rapidly；
3. 第3空：固定搭配“it + adj + for sb + to do sth”，表示“对某人来说做某事是……的”，故选get along with并转换为不定式to get along with；
4. 第4空：句意为工作人员持续宣传直到游客养成好习惯，需表“直到”的连词，选till；
5. 第5空：句意为有礼貌的游客会带走垃圾，all后接名词复数，给定词tour转换为名词tourist的复数tourists。
