【解析】

试题分析：这篇短文讲述的是睡眠对于我们的身体健康来说是很重要的，如果我们有了充足的睡眠，白天的时候我们才能有充足的精力学习、工作；相反如果睡眠不充足，我们就会感到疲惫。睡觉时我们的身体需要很多新鲜空气，这样我们醒来的时候才不会感到疲惫。

1.细节理解题。根据短文中Our body grows most when we are asleep.可知，当我们睡觉的时候，我们的身体长得最快。这句话中asleep是睡着的，跟选项中sleeping是同一个意思。故选C。

2. who are tired usually need sleep可知，感到疲惫的孩子需要睡眠，由此我们可以推断出，如果我们睡眠不足，就会感到疲惫。故选A。hungry 饿的；happy 开心的；grow长大，这三个不符合文意。

3.细节理解题。根据短文中If we do not get enough fresh air, we will feel tired when we wake up.可知，如果我们不能得到充足的新鲜空气，当我们睡醒的时候我们就会感到疲惫。由此可知选B。
