"According to a recent study, people with many social ties report catching colds less often than do people with few social ties. Consequently, researchers conclude that having an active social life probably helps strengthen the immune system. The researchers note that catching a cold—one of a family of highly contagious viruses—gives the cold-sufferer temporary immunity to that virus in the future, but not to the many other related viruses. Merely being exposed to a new cold virus, however, is not enough for a person to catch a cold, since a strong immune system can successfully fight off some new viruses. Thus, in order to prevent catching a cold, people should strengthen their immune systems by becoming more active socially."

我觉得这条题目的内在逻辑是
社交活动会增强免疫系统,强大的免疫系统能让人不得感冒

我想可以反驳的地方是

1.  社交活动是否能增强免疫系统,study并不能证明这一点,很可能是免疫系统本来就强的人身体好,参加的社交活动多,而不是社交多了免疫系统就好了,因果关系颠倒;
2.一次感冒能增强临时的免疫系统,参加社交活动的人都会得感冒,从而免疫系统暂时加强么?
3.
就算社交活动能增强免疫系统,是否能增强成强壮的免疫系统?通过社交活动得了一次感冒后,只是能起暂时免疫的作用,而且还不是对所有的病毒。
  
4
参加社交活动,反而增加接触病毒的机会,更可能得感冒。

觉得第2条有点想的不顺,因为我觉得题目中没有说参加社交活动就能得一次感冒,使人得到临时免疫,我可以这样说么?
