前段时间为gre考生汇总了gre issue写作提纲思路和分析，希望对考生在攻破gre issue写作上有所帮助。接下来的几天我们将为gre考生整理gre argument部分的提纲内容。希望通过我们的整理和汇总，让gre考生真正能掌握gre写作的精髓。 题目题材：保健 gre argument 59题目： The following appeared in an article in the health section of a newspaper. According to the available medical records, the six worst worldwide flu epidemics during the past 300 years occurred in 1729, 1830, 1918, 1957, 1968, and 1977. These were all years with heavy sunspot activitythat is, years when the Earth received significantly more solar energy than in normal years. People at particular risk for the flu should therefore avoid prolonged exposure to the Sun. 提纲： The writer provides no direct evidence to prove that it is the solar energy that resulted in the flu epidemics. The writer fails to inform us about the severity of the disease in years when sunspot activities were less heavy. Granted that heavy sunspot activity did result in the flu epidemics, exposure to the Sun in normal years may not have the same effect. Exposure to the sun may have some positive effects for human health, thus we could not hastily conclude that people should avoid it. |
