本题考查七年级核心语法点，逐空解析如下：
1. 考查固定搭配spend time (in) doing sth.，意为“花费时间做某事”，因此动词play变为动名词形式playing。
2. 考查不定式作目的状语，此处表示“去操场的目的是和同学们一起锻炼”，用to take表动作的目的。
3. 考查find的复合结构find sth. +形容词，此处it指代踢足球这件事，修饰事物要用形容词interesting，意为“有趣的”。
4. 考查介词用法，“for + 时间段”表示动作持续的时长，此处指放学后踢球的时长，填for。
5. 考查一般过去时，全文描述过去的经历，谓语动词要用过去式，score的过去式为scored。
6. 考查副词用法，此处需要修饰动词improve，要用副词形式，形容词quick对应的副词是quickly。
7. 考查if引导的条件状语从句的“主将从现”规则，从句用一般现在时，主句要用一般将来时，填will get。
8. 考查动名词作主语，此处要在宾语从句中充当主语，需要把动词win变为动名词winning。
9. 考查固定搭配enjoy oneself，意为“玩得开心”，we对应的反身代词是ourselves。
10. 考查形容词性物主代词，此处修饰名词lessons，要用I对应的形容词性物主代词my。
