我们逐空分析解题依据：
1. 第1空：主语the weather是不可数名词，句子为一般现在时，be动词用is。
2. 第2空：Right now是现在进行时的标志，结构为"be+现在分词"，主语my family and I是复数，be动词用are，have的现在分词为having，故填are having。
3. 第3空：固定搭配very much意为"非常"，用来修饰动词enjoys，符合语境，故填much。
4. 第4空：固定短语take photos of... 表示"拍摄……的照片"，符合此处拍湖水和沙滩照片的语境，故填of。
5. 第5空：此处和形容词green并列作表语，需要把动词live变为形容词lively，意为"生机勃勃的"，用来描述植物的状态。
6. 第6空：stone是可数名词，此处表示捡多块漂亮的石头，要用复数形式stones。
7. 第7空：固定搭配tell sb. about sth. 意为"向某人讲述/介绍关于……的内容"，符合句意，故填about。
8. 第8空：此处修饰名词scenery，需要把名词beauty变为形容词beautiful，意为"美丽的"。
9. 第9空：此处修饰名词story，表示"这个湖的故事"，要用名词所有格形式lake's。
10. 第10空：此处是不定式作后置定语修饰名词place，构成结构a great place to do sth. 表示"做某事的好地方"，故填to spend。
