such as Arctic explorers,often get a cold or two at first and then have several months free from colds.However,when the supply ship arrives the colds start again.
(explain this phenomenon,not translate the sentence)

居住在这个封闭的,与世隔绝的地区的人们,试图去解释这个现象:

比如北极圈的探险这,最开始会遭遇一两个月的寒冷天气,接下来的几个月又恢复温暖,然后,当运送供给的船只到达时,寒冷的天气又开始了

因为每一个人的每一次感冒都是由不同的感冒病毒引起的，而寒冷的地区部适合感冒病毒的生存，在没有外界引入的条件下，人们不会重复地患感冒，而伴随补给船的到来，新的感冒病毒也随之而来

珊瑚同志 你错了 这里的cold是指感冒
um.. how to say this, it's like if you are alone, all by yourself from the very begining, you don't feel lonely, but when later you meet someone and fall in love with him, but one day he suddenly left you, you feel disasterous and terribly lonely.
when you don't get to know the feeling of warmth, you don't feel cold, because you have no idea what cold is, what it means, and how it feels.
