GRE argument 123题目：
The following appeared in a health newsletter.
"Eating a heavy meal may increase the risk of heart attack. A recent survey of 2,000 people(1) who had had a heart attack revealed that 158 of them(2) said they had eaten a heavy meal within 24 hours before their heart attack, and 25 of them said they had eaten a heavy meal within 2 hours before their heart attack(3). Eating and digesting food releases hormones into the bloodstream and temporarily increases heart rate and blood pressure slightly(4). Both of these things put stress on the heart. Therefore, people who are at risk of having a heart attack can lower that risk by not overeating(5)."
提纲：
(1)The result of the survey lacks reliability because 2,000 people could constitute only a very limited sample.
(2)158 out of 2,000 people are so insignificant a proportion that could hardly be statistically representative.
(3)The author unfairly assumes that it is the heavy meals that resulted in the heart attack of people cited in the survey.
(4)The author does not inform us to what extent will overeating increase heart rate and blood pressure, and if the increase will sufficiently cause heart attack.
(5)Since heart attack may result from many factors, the author’s assumption that avoiding overeating would sufficiently lower the risk of heart attack is unwarranted.
注：题目中括号里的数字表明这句话体现的是提纲中第几号缺陷。
无论是gre issue还是gre argument，考生都应该养成写提纲的习惯。这种提纲式的gre写作练习可以帮助考生锻炼写作的逻辑性，而gre写作高分最重要的得分依据就是作文的逻辑性要强。希望大家都能写出好作文。
