答案
【解析】：我们结合句意、基础语法和固定短语搭配逐一确定答案：
1. 空前有不定冠词a修饰，需要填入表身份的可数名词单数，student符合语境，意为“我是一名中学生”。
2. 固定搭配do exercise意为“做运动”，符合前文提到的热爱运动的语境。
3. 固定搭配on the playground意为“在操场上”，是进行篮球等户外运动的常见地点。
4. 主语Our PE teacher是第三人称单数，句子为一般现在时，谓语动词要变为第三人称单数形式，teach的第三人称单数是teaches，此处表示体育老师教我们做不同的运动。

6. 此处需要副词修饰动词短语play computer games，频度副词always符合语境，描述不爱运动的学生的日常习惯。

9. 空后是名词friends，用形容词new修饰，new friends意为“新朋友”，符合运动的益处的语境。
