No matter where we are on earth, air surrounds us. We live in air.All living things need air. Living things cannot live without air. We can go without food or water for a few days, but we cannot live for more than a few minutes without air. When we are working or running, we need more air. So we breathe faster than usual. When we are asleep, we need less air.

选项 A、a few months
B、a few weeks
C、a few days

解析 根据第二段第三句We can go without food or water for a few days…可知我们可以几天不吃饭、不喝水。所以应选C。
