"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."



The argument conclude that people shoudl strengthen their immune systems by becoming more active socially in order to prevent catching a cold.To support the conclusion the author cites certain study and some analysis. This argument is problematic in several respects,rendering the argument unconvincing as is stands.

To begin with, the author provides no evidence that the study's result is statistically reliable. In order to establish a strong correlation between the frequency of social life
and the possibility of catching a cold, the study's sample must be sufficient in size and representative of the overall population of cold. Lacking evidence of a sufficient
representative sample, the author cannot justifiably rely on the study to draw any conclusion whatsoever.

Even assuming that the study is statistically reliable, the argument unfairly assumes that active social life helps strengthen the immune system. It is entirly possible that active
social life is not beneficial to improving the immune system at all, even increasing the risk of being infected by viruses as result of too much contacting with people in the period of influenza.Lacking better evidence that more social activities advance the immune system the argument remains unconvincing.

Finally, even if more social activities strengthen the immune system, the author provide no firm evident that strengthening the immune system can aviod getting cold. The author overlook such a possibility that some new viruses which be fighted off by a strong immune system may not involve cold ones. Thus, the argument cannot convince me that people can prevent catching a cold via strengthening their immune systems.

In sum, the argument is logically flawed and therefore unconvinceing as it stands. To strengthen it the author must provide clear evidence that more social life in fact helps to strengthen the immune systems and a strong immune system actually prevent to catch a cold. Moreover, we would need more information about the sampling method used in the study.

This argument is problematic in several respects,rendering the argument unconvincing as is stands.

To begin with, the author provides no evidence that the study's result is statistically reliable. In order to establish a strong correlation between the frequency of social life and the possibility of catching (susceptibilities to) a cold, the study's sample must be sufficient in size and representative of the overall population of cold. Lacking evidence of a sufficient representative sample, the author cannot justifiably rely on the study to draw any conclusion whatsoever.

Even assuming that the study is statistically reliable, the argument unfairly assumes that active social life helps strengthen the immune system. It is entirly possible that active
social life is not beneficial to improving the immune system at all, even increasing the risk of being infected by viruses(这一段说的是社交生活和免疫系统之间的关系，而你这里说的是社交生活和感染感冒之间的关系) as result of too much contacting with people in the period of influenza.Lacking better evidence that more social activities advance the immune system the argument remains unconvincing.

Finally, even if more social activities strengthen the immune system, the author provide no firm evident that strengthening the immune system can aviod getting cold.

语言流畅，但感觉论据不是很充分，这大概也是这道题被列为难题的原因吧！
