做这类英语阅读判断正误题，需先通读短文把握大意，再逐题定位短文中的对应语句，将题目表述与原文内容逐一对比，表述一致则判断为T，不一致则为F。
【解析】
1. 题目表述“Air is only around us when we play”与原文不符，原文第一段提到空气在行走、玩耍、坐卧、睡觉时都围绕着我们，并非仅在玩耍时存在，故判断为F。
2. 题目表述“People can live for many days without food or water”与原文不符，原文第二段明确说明人离开食物和水只能存活几天，并非很多天，故判断为F。
3. 题目表述“We need more air when we run”与原文一致，原文第二段提到跑步时需要更多空气，故判断为T。
4. 题目表述“We can see air everywhere”与原文不符，原文第二段指出我们生活在空气中但看不见它，故判断为F。
