但是,在过去几十年,医学上意识到实际上大多数普遍存在的感冒病毒对我们的细胞几乎没有什么危害。
You can catch a cold or the flu at any time of year, but it's more prevalent in winter, when we spend more time in close proximity with other people (A.K.A. germ-bearers!) and in warmer, drier air.我们在一年中的任何时节都会患感冒或者流感,只是在我们与其他人更加亲近(又称为细菌承载体)而且是温暖、干燥的冬季里,这种疾病更加流行。
If the sun's influence alone were prevalent, there would be no change at all during our seasons; once cold or warm, it would invariably continue to be so, according to the time of the year.如果大地只有太阳的普照,那么每年的各个季节中,天气就不会有什么差别,夏天一样的热,冬天一样的冷,天气就会这么一年一年的一成不变地循环。
